Background/Objectives: The Child Oral Health Impact Profile—Short Form 19 (COHIP-SF 19) is widely used to measure the oral health-related quality of life (OHRQoL) of children and adolescents. The current study aimed to validate the Malay language version of the COHIP-SF19 (ML COHIP-SF 19) and to assess its psychometric properties among Malaysian children/adolescents. Methods: Children aged from 9 to 16 years attending the Faculty of Dentistry, Universiti Teknologi MARA (UiTM) participated in this study. The original English version of the COHIP-SF 19 was translated using forward- and back-translation. The psychometric properties of the final version were tested for reliability and validity using Cronbach’s alpha, a non-parametric Spearman’s correlation test, and confirmatory factor analysis (CFA). Results: A total of 252 children aged from 9 to 16 years (mean age = 11.33 ± 1.87 years) self-completed the ML-COHIP-SF 19. The total scores of the ML COHIP-SF 19 ranged from 20 to 75 (mean = 55.67 ± 10.45) with an internal consistency (α) of 0.81. Convergent validity showed a fair correlation between self-perceived oral health rating and total ML COHIP-SF 19 scores, as well as the socio-emotional well-being subscale scores (rs = 0.38–0.42, p < 0.01). Conclusions: The ML COHIP-SF 19 demonstrated reliable psychometric properties and acceptable four-factor model fits, indicating that it is a valid tool to measure the OHRQoL of Malaysian children aged from 9 to 16 years.

Objectives: To investigate whether hypodontia and other developmental dental anomalies were more common in children with MIH than their unaffected peers, and to determine if sex or geographical location had any effect on hypodontia prevalence. Methods: This analytical cross-sectional study was conducted in specialist paediatric dentistry clinics across 14 countries, categorised into six geographical regions. A total of 1279 children (aged 6- 17 years) underwent a clinical examination and were allocated to the MIH (n = 649) or comparison group (n = 630). A validated MIH index was used to record the presence/extent of any hypomineralisation and a standardised approach was used to establish the clinical and/or radiographic presence of ten developmental dental anomalies. Results: Four anomalies were significantly more prevalent in participants with MIH than those without this condition: hypodontia (p = 0.047), dens invaginatus (p = 0.004), dens evaginatus (p < 0.001) and microdont maxillary lateral incisors (p = 0.01). Additionally, the adjusted odds of hypodontia were 1.49 times higher in children with MIH compared to those without MIH. There was considerable disparity between geographic locations with the highest prevalence of hypodontia in participants from the Western Pacific region (11.21 %) and the lowest (2.92 %) in the Americas. No statistically significant association was found between sex (male vs. female) and hypodontia (p = 0.839). Conclusions: Accepting that the study group may not be representative of the wider population, the findings still have important clinical relevance. Furthermore, they lend support to the concept of shared genetic and epigenetic influence in the aetiology of MIH and other developmental dental disorders.

Objective The present study aimed to investigate the impact of utilizing an innovative and comprehensive patient-centered digital clinical decision aid designed to facilitate shared decision-making in missing tooth replacement between dental students and their patients. Methods A qualitative study using interview approach was conducted in Hong Kong SAR and Malaysia. Thirty dental undergraduate students, each with one patient from the Faculty of Dentistry at The University of Hong Kong (n = 15) and Universiti Teknologi MARA (n = 15), were introduced to a digitally designed decision aid in missing tooth replacement prior to their treatment appointments. Semi-structured interviews were conducted with each student and patient, adhering to the interview protocol. Each interview was audio-recorded, transcribed, and subsequently coded to investigate the perceptions and potential advantages of this decision aid. Results Thematic analysis identified three key themes from the dental students' perspective: communication, utilization, and satisfaction. From patients' perceptions, four central themes emerged: communication, treatment information, uncertainty, and utilization. Detailed examination of the data highlighted an enhancement in patients' confidence and trust in their dental care providers, as well as a marked increase in both student and patient satisfaction levels upon implementing this novel approach. The average satisfaction rates for students were 83 % for Hong Kong SAR and 82 % for Malaysia. Conclusion This patient-centered clinical decision aid helped to enhance communication between dental students and patients in both regions, ultimately leading to heightened patient satisfaction levels. Nonetheless, to address the present study's limitations, future studies should consider diversifying participant backgrounds, including patients without prior treatment discussions with students. Clinical significance Clinical decision aids are valuable tools in clinical teaching due to their enhancement of communication between clinicians and patients. They promote shared decision-making, leading to more personalized and evidence-driven treatment plans, ultimately improving patient care.

BACKGROUND:Resin infiltration is used to mask enamel opacities and the recommended etching cycles are three. However, anecdotal evidence suggests that favorable esthetics outcomes can be obtained by increasing the etching cycles.AIM:To determine the incremental and total enamel loss when enamel surfaces are exposed to multiple etching cycles and to assess the relative attenuation coefficient after multiple etching cycles and resin infiltration treatment.METHODS:Ninety extracted sound human premolars teeth were divided into 9 groups (n = 10); with each consecutive group having one additional etching cycle up to 9 cycles. The teeth were scanned with optical coherence tomography and enamel loss and attenuation coefficient were measured with MATLAB software. Enamel loss (one-way ANOVA, p ≤ 0.05) and attenuation coefficient (two-way ANOVA, p ≤ 0.05) were statistically analyzed.RESULTS:There was a significant total enamel loss of more than 33% found at the 7th etching cycle and more. There was no statistically significant difference in the incremental mean depth of penetration of resin between various etching cycles (F(8, 134) = [2.016], one-way ANOVA, p = 0.185).CONCLUSION:This study recommends that etching should not be repeated more than seven cycles to prevent excessive enamel loss. Following eight etching cycles, resin infiltration penetration appears approximately equal to that of healthy enamel.

AimThe COVID-19 pandemic has accelerated teledentistry research with great interest reflected in the increasing number of publications. In many countries, teledentistry programs were established although not much is known about the extent of incorporating teledentistry into practice and healthcare systems. This study aimed to report on policies and strategies related to teledentistry practice as well as barriers and facilitators for this implementation in 19 countries.MethodsData were presented per country about information and communication technology (ICT) infrastructure, income level, policies for health information system (HIS), eHealth and telemedicine. Researchers were selected based on their previous publications in teledentistry and were invited to report on the situation in their respective countries including Bosnia and Herzegovina, Canada, Chile, China, Egypt, Finland, France, Hong Kong SAR, Iran, Italy, Libya, Mexico, New Zealand, Nigeria, Qatar, Saudi Arabia, South Africa, United Kingdom, Zimbabwe.ResultsTen (52.6%) countries were high income, 11 (57.9%) had eHealth policies, 7 (36.8%) had HIS policies and 5 (26.3%) had telehealth policies. Six (31.6%) countries had policies or strategies for teledentistry and no teledentistry programs were reported in two countries. Teledentistry programs were incorporated into the healthcare systems at national (n = 5), intermediate (provincial) (n = 4) and local (n = 8) levels. These programs were established in three countries, piloted in 5 countries and informal in 9 countries.ConclusionDespite the growth in teledentistry research during the COVID-19 pandemic, the use of teledentistry in daily clinical practice is still limited in most countries. Few countries have instituted teledentistry programs at national level. Laws, funding schemes and training are needed to support the incorporation of teledentistry into healthcare systems to institutionalize the practice of teledentistry. Mapping teledentistry practices in other countries and extending services to under-covered populations increases the benefit of teledentistry.

Aims and Objectives: The aim of this study was to systematically review the ability of resin infiltration to conceal demineralized enamel lesions to normal enamel translucency and to maintain color stability.Materials and Methods: A literature search of PubMed, MEDLINE, Web of Science, and Scopus databases and a manual search of articles from 2009 to 2021 for randomized controlled trials (RCTs) and clinical efficacy trials (nonrandomized) were performed. Methodological quality and risk of bias (RoB) of included papers was assessed using Cochrane Collaboration Risk of Bias Tool 2.0 for RCTs and ROBINS-I (Risk Of Bias In Non-randomized Studies of Interventions) tool for nonrandomized studies.Results: A total of 352 titles and abstracts were reviewed. Eight RCTs and three clinical efficiency studies were included in this review. The masking effects of the demineralized enamel lesion were reported immediately after resin infiltration, and the color stability of this material was up to 24 months, with no adverse effects noted. For RCTs, four studies were classified as "some concerns" and four were as "low RoB." For nonrandomized studies, all of the studies presented an overall moderate RoB.Conclusion: Resin infiltration achieves the best esthetic outcomes compared with microabrasion and remineralization therapy. Color stability was achieved with this material for up to 24 months and no adverse effects were noted. Factors contributing to the esthetic outcomes of the resin include the elimination of the hypermineralized surface layer, the homogeneity of the resin itself, and polishing after resin infiltration. Longitudinal follow-up and improved control of confounding variables should characterize future high-quality systematic reviews.

A bstract Aims and Objectives: Studies on resin infiltration and its penetration capability are becoming the focus of emerging dentistry. The depth of resin penetration could be a key determining factor in creating a diffusion barrier and in the success of infiltration. The aim of this review article was to evaluate the penetration depth of commercially available resin infiltration in early caries lesions and to identify factors that influence the penetration capability of resin infiltration. Materials and Methods: A literature search was performed in four databases (PubMed, Science Direct, Scopus, and Web of Science) and manual searching from 2009 to December 2022. Eligibility criteria included in vitro studies pertaining to factors affecting the penetration depth of resin infiltration into the enamel. The risk of bias assessment was done by using checklist for reporting in vitro studies (CRIS). Results: The initial search resulted in a total of 297 studies. Twenty-nine were assessed for eligibility, and 23 were selected in the qualitative synthesis. According to the CRIS guidelines, all of the studies were classified as moderate risk of bias. The penetration of resin infiltration is influenced by the enamel surface treatment with hydrochloric acid, formulations containing triethylene glycol dimethacrylate (TEGDMA), the addition of ethanol, penetration time, duration of penetration time, saliva contamination, caries activity, and type of tooth. The hypermineralized surface layer needs to be removed for better resin perfusion. Conclusion: The key to optimal resin infiltration depends on the enamel surface treatment with hydrochloric acid and application technique, infiltration duration, formulation of TEGDMA and ethanol in the resin composition, as well as the type and caries activity of involved teeth. Resin infiltration has superior penetrability compared to fissure sealant, casein phosphopeptide-amorphous calcium phosphate nanocomplexes, flowable composite, adhesive and fluoride varnish. Resin penetration depth may be a critical factor in forming a diffusion barrier and the effectiveness of infiltration in halting the progression of caries.

Resin infiltration (RI) is used to mask enamel opacities. There are three recommended etching cycles. However, anecdotal evidence suggests that favorable esthetics outcomes can be obtained by increasing the etching cycles. This study aimed to evaluate the effects of repeated etching cycles during RI application on esthetic changes and surface roughness of demineralized enamel at multiple treatment stages. Artificial demineralization was prepared on the buccal surface of ninety sound extracted premolars. The teeth were divided into nine groups (n = 10); with each consecutive group having one additional etching cycle up to nine etching cycles. Resin infiltrant was performed twice, first for 3 min (Resin 1) and again for 1 min (Resin 2). Surface roughness and esthetic changes were assessed using a profilometer (Ambios XP-200) and Minolta spectrophotometer, respectively, at baseline (sound enamel), etching, resin 1, resin 2, 7 days, and 28 days post resin applications. Data were analyzed with two-way ANOVA (p < 0.05). There was a significant interaction between the different stages and various groups of etching cycles on surface roughness, F(48, 126) = 3.48, p < 0.001. There was a significant interaction between the different stages and various groups of etching cycles on color changes, F(4, 126) = 1.177, p = 0.045. The surface roughness of demineralized enamel infiltrated with RI was less than that of sound enamel (baseline). There is a significant difference in color changes between resin 1 and resin 2 (p < 0.05). After five etching cycles, RI improved the esthetic of the color of teeth similar to the baseline. Surface roughness and color changes remained constant for 28 days. RI can be considered an effective and predictable treatment option for the restoration of early enamel lesions owing to its better surface characteristics and reliable masking effects. The color stability and surface roughness stay unaltered for up to 28 days.

Background: Molar incisor hypomineralisation (MIH) is a common disorder of tooth development, which has recently been found to be associated with a higher prevalence of hypodontia. The aim of this international multicentre study is to determine the association between MIH and other developmental anomalies in different populations. Methods: Investigators were trained and calibrated for the assessment of MIH and dental anomalies and ethical approvals obtained in each participating country. The study aimed to recruit 584 children with MIH and 584 children without MIH. Patients aged 7–16 years who attend specialist clinics will be invited to participate. Children will undergo a clinical examination to determine the presence and severity of MIH, using an established index. The presence of any other anomalies, affecting tooth number, morphology, or position, will be documented. Panoramic radiographs will be assessed for dental anomalies and the presence of third permanent molars. Statistical analysis, using a chi squared test and regression analysis, will be performed to determine any differences in dental anomaly prevalence between the MIH and non-MIH group and to determine any association between dental anomalies and patient characteristics. Conclusion: This large-scale study has the potential to improve understanding about MIH with benefits for patient management.

BACKGROUND:Children with molar-incisor hypomineralisation (MIH) frequently seek aesthetic treatment for incisor opacities. Surprisingly, few studies have evaluated the clinical success of such interventions. AIM:To quantify the effectiveness of minimally invasive treatments in reducing enamel opacity visibility in children with MIH. DESIGN:This in vitro study used digital clinical images of 23 children aged 8-16 years with MIH who underwent microabrasion and/or resin infiltration for the management of incisor opacities. Standard images were taken pre-treatment and 6 months post-treatment. Image software (Image-Pro Plus® V7) was employed to convert 24-bit RGB images to 16-bit greyscale and 145× magnification. Measurement repeatability was assessed using intra-class correlation coefficients (ICCs). Post-treatment changes in visible opacity area (mm2 ) and brightness (greyscale value) were tested using the Wilcoxon signed-rank test for related samples. RESULTS:The mean total opacity surface area significantly reduced from 14.3 mm2 (SD = 7.5) to 9.4 mm2 (SD = 9.0) post-treatment. The proportion of tooth surface affected by the opacity also significantly reduced from 22.5% (SD = 10.5) to 14.7% (SD = 12.7). The mean maximum opacity brightness significantly reduced from 53 066 greyscale value (SD = 4740) to 49 040 (SD = 3796). ICC was good/excellent (0.75-1.0). CONCLUSION:Minimally invasive treatment is effective in reducing the size and brightness of discrete incisor opacities. Future research should compare objective findings with patient-reported outcomes.

To explore the range of impacts relating to incisor opacities as described by children, their general dental practitioners and paediatric dentists. Participants included 50 children, aged 7–16 years, referred to a UK hospital paediatric dentistry service for management of incisor opacities. All children were subsequently diagnosed with molar incisor hypomineralisation. Following ethical approval, data were recorded as follows: patient demographics, distance travelled, waiting times, nature of any impacts relating to incisor opacities documented in referral letters and/or in subsequent paediatric dentistry assessment records. Additionally, children completed the short form Child Oral Health Impact Profile questionnaire (COHIP-SF19) as a self-report measure of their oral health-related quality of life (OHRQoL). Nearly, half (48%, n = 24) of the referral letters mentioned that the child was experiencing one or more negative social and/or functional impacts. Mean COHIP score was significantly lower (indicating poorer OHRQoL) for children whose referring dentist had identified a negative impact (COHIP = 42.9) compared to those with no documented impact (COHIP = 50.5; p = 0.018, independent t test). At the hospital consultation, negative impacts were elicited by a paediatric dentist in 86% (n = 43) of cases. Again, mean COHIP score was significantly lower for children whose assessment records noted a negative impact (COHIP = 44.5) compared to those with no recorded impact (COHIP = 60.2; p = 0.001). Families travelled a mean distance of 57 km (range 3–218 km) to the hospital service, with an average waiting time of 75 days from referral. It is encouraging that dental professionals seem to be aware of the negative psychosocial impacts experienced by some children with enamel opacities, and that children feel able to describe them.

Background Molar Incisor Hypomineralisation (MIH), with a global prevalence of 12-14%, is one of the most common developmental defects of enamel (DEE) to affect children. The condition is associated with considerable functional and aesthetic problems with visible incisor opacities potentially having a negative impact on children’s social interaction and self-esteem. This prospective clinical study is the first to evaluate the impact of minimally invasive dental treatments, aimed at improving the appearance of enamel opacities associated with MIH, on children’s oral health-related quality of life and overall well-being. Aim This study aimed to explore the relationships between socio-demographics, clinical status and oral health-related quality of life (OHRQoL) in children with MIH who received aesthetic treatment for their incisor opacities. Materials and methods This clinical study involved children, aged 7-16 years, referred to a UK Dental Hospital for management of permanent anterior teeth enamel opacities of reported cosmetic concern. Following ethical approval, participants completed a number of validated questionnaires, primarily the C-OHIP-SF19, Harter’s Self-Perception Profile for Children (SPPC) and the Friends and Family Test, prior to any intervention (T0). Treatment regimens included: microabrasion, resin infiltration (Icon™, DMG), tooth whitening, composite resin restoration or a combination of treatments. The recruitment, treatment and subsequent visits were conducted from June 2017 to October 2018. Children were reviewed after one (T1) and six (T2) months, completing the questionnaires each time. Clinical photos were taken at each time point. Change in children’s OHRQoL and self-concept at T0, T1 and T2 were analysed using the Friedman’s Two Way Analysis of Variance by Rank and Wilcoxon Signed Rank tests. Links between predictors, the socio-emotional wellbeing domain of C-OHIP-SF19 and children’s OHRQoL were assessed using structural equation modelling and were underpinned by a theoretical model of HRQoL proposed by Wilson and Cleary. Results Of 111 children initially invited, 103 consented to participate and 86 were reviewed at 6-months (83% completion rate). They had a mean age of 11-years (range 7-15), 60% were female and the majority (92%) were White British/Northern European. Most children (56%) received a combination of microabrasion and Icon™. Children were very positive about the treatment they had received (100% likely to recommend their care to friends and family). The total and all C-OHIP-SF19 domain scores were significantly increased following treatment, indicating substantial improvement in OHRQoL (p<0.001). In addition, there was a significant change in the SPPC, Physical Appearance subscale scores, reflecting children’s perceptions that they looked better following treatment (p<0.001). Within the Wilson and Cleary model, a higher number of anterior teeth requiring aesthetic treatment was linked to lower socio-emotional wellbeing scores at T2 (s=-0.179, p<0.01). Greater need for orthodontic treatment at baseline was related to worse OHRQoL at T2 (s=-0.154,p<0.05). Higher self-concept at baseline was significantly associated with higher OHRQoL and socio-emotional wellbeing at baseline (s=0.460,p<0.01 and s=0.254,p<0.05). Self-concept at baseline indirectly predicted socio-emotional wellbeing at six-months follow-up, via socio-emotional wellbeing at baseline (s=0.197, p<0.01). Conclusions This is the first study to explore and demonstrate the simultaneous effects of clinical status, self-concept, socio-emotional wellbeing and children’s OHRQoL following simple aesthetic treatment for incisor opacities associated with MIH. Whilst minimal interventions for incisor opacities undoubtedly improve children’s OHRQoL, a number of complex psychosocial factors and clinical confounders may influence this overall outcome.

Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected children. Objectives Here, we provide an up-to-date review of the epidemiology, aetiology, diagnosis and clinical management of MIH. Materials and methods A review of the contemporary basic science and clinical literature, relating to MIH, was undertaken using information obtained (up to 10 April 2020) from the electronic databases PubMed, Scopus, Web of Science and the Cochrane Library. Results There is a growing body of evidence relating to the aetiology, presentation and clinical management of MIH. Current knowledge appears to be focused on potential genetic aspects, as well as the development and validation of indices for the diagnosis and management of MIH. There has also been increasing recognition of the global and individual burden of this common condition. Conclusions Dental health professionals should regularly appraise the basic science and clinical MIH literature to ensure that they provide the best possible short- and long-term care for their young patients.

Objectives: To identify clinical and psychosocial predictors of oral health-related quality of life (OHRQoL) in children with molar incisor hypomineralisation (MIH) following aesthetic treatment of incisor opacities. Methods: Participants were 7- to 16-year-old children referred to a UK Dental Hospital for management of incisor opacities. Prior to treatment (To), participants completed validated questionnaires to assess OHRQoL and overall health status (C-OHIP-SF19), and self-concept (Harter's Self-Perception Profile for Children [SPPC]). Interventions for MIH included microabrasion, resin infiltration, tooth whitening or composite resin restoration. Children were reviewed after six months (T-1) when they re-completed the C-OHIP-SF19 and SPPC questionnaires. The relationships of predictors with improvement of children's OHRQoL (T-1-T-o) and children's overall health status at T-1 were assessed using linear and ordinal logistic regression respectively, guided by the Wilson and Cleary's theoretical model. Results: Of 103 participants, 86 were reviewed at T1 (83.5 % completion rate). Their mean age was 11-years (range = 7-16) and 60 % were female. Total and domain OHRQoL scores significantly increased (improved OHRQoL) following MIH treatment. There was a significant positive change in SPPC physical appearance sub scale score between T-o and T-1. A higher number of anterior teeth requiring aesthetic treatment were associated with poor improvement of socio-emotional wellbeing at T-1 (Coef =-0.43). Higher self-concept at To was associated with greater improvement of socio-emotional wellbeing at T-1 (ss = 3.44). Greater orthodontic treatment need (i.e. higher IOTN-AC score) at T-0 was linked to worse overall oral health at T-1 (OR = 0.43). Conclusions: Psychosocial factors and dental clinical characteristics were associated with change in children's OHRQoL following minimal interventions for incisor opacities. Clinical significance: MIH is a common condition and clinicians should be aware of the negative impacts some children experience, particularly those with multiple anterior opacities, poor tooth alignment and low selfconcept. However, simple, minimally invasive treatments can provide good clinical and psychosocial outcomes and should be offered to children reporting negative effects.

Background Clinical observations suggest molar incisor hypomineralisation (MIH) may present with other dental conditions. Aims The study aimed to determine the prevalence and variety of dental anomalies in children presenting with MIH. Design A convenience sample of children referred to a UK dental hospital was recruited. Orthopantogram radiographs, taken as part of routine care, were assessed for dental anomalies. Two calibrated examiners reviewed the films separately and determined the presence and character of anomalies. Results Radiographs were obtained from 101 patients, with an age range of 6-15 years. Co-existing hypodontia was identified in 12%, with lower second premolars being the most commonly missing teeth. Concurrent ectopic first permanent molars were identified in 8%, and infraocclusion of one or more primary molars was identified in 9%. Abnormal morphology was found in 9%, including macrodont and microdont teeth. In total, 29% of patients had an associated dental anomaly. Examiners had perfect agreement using Cohen's kappa coefficient. Conclusion This high prevalence of dental anomalies, particularly hypodontia, in children with MIH is a novel and clinically important finding. Further research is warranted considering the potential implications for assessment and treatment planning.

OBJECTIVES: To compare the preferences of patients and clinicians perception towards two different methods of audiovisual distraction in behavior management approach. MATERIAL AND METHODS: A total of 21 children were included in this study. The children were assessed over two visits during which they were given different types of audiovisual distraction which were a cartoon show and an interactive game. Children\'s pre-operative anxiety level was assessed using the Facial Image Scale (FIS). The pulse rate of the patients was taken using pulse oximeter during 5 stages of dental treatment on a patient. A post-op modified MCDAS questionnaire was given to the patient to measure the patient-perceived pain level. A self-administered questionnaire was also given to the operator after the treatment to assess the operator\'s perception in using audiovisual distraction in managing paediatric patients. RESULTS: There were no statistically significant differences in heart rate between cartoon and interactive games, but it was noted that there was a significant increase in the heart rate during administration of local anaesthesia, followed by placement of clamp. Besides that, there were significantly different in MCDAS scoring between cartoon and games, which showed patients with cartoon, had lowered score compared to interactive games. (p<0.05) CONCLUSION: Result of this study showed that both types of audiovisual distraction, interactive games and cartoon are effective in reducing anxiety among paediatric dental patients. Although there was no significant difference in heart rate, the children seemed to prefer cartoons over games. The preferred method of audiovisual distraction among clinicians was also cartoon. Keywords: audiovisual distraction, paediatric patient, dental anxiety.

Molar incisor hypomineralisation (MIH) is a common enamel condition, presenting with incisor opacities, which may be of psychosocial concern to children. This clinical study sought to determine whether minimally invasive treatment, aiming to improve incisor aesthetics, would also improve children's oral health-related quality of life (OHRQoL). 111 MIH patients, aged 7⁻16 years, referred to a UK Dental Hospital, were invited to complete the Child Oral Health Impact Profile (C-OHIP-SF19) prior to any intervention (T₀) and again at one-month following the intervention (T₁) for MIH. Treatment regimens included one or more of the following: Microabrasion; resin infiltration; tooth whitening; resin composite restoration. Data were obtained for 93 children with a mean age of 11 years. Mean total C-OHIP-SF19 score at T₀ was 47.00 (SD = 9.29; range = 0⁻76) and this increased significantly at T₁ to 58.24 (SD = 9.42; range = 0⁻76; p < 0.001, paired t-test), indicating a marked improvement in self-reported OHRQoL. There were no statistically significant differences according to gender. This is the first study to show that simple, minimally invasive dental treatment, to reduce the visibility of enamel opacities, in MIH, can have a positive impact on children's wellbeing.
