Background and Objectives: Traumatic dentoalveolar injuries (TDI) in children often require urgent stabilization using splints. Titanium trauma splints (TTS) represent a practical option; however, pediatric evidence from hospital-based emergency settings remains limited. This study describes the clinical and contextual characteristics of children treated with TTS and explores factors associated with early complications and splint stability. Materials and Methods: A retrospective observational cohort study was conducted at a Pediatric Dentistry Service, including children with TDI managed with TTS and followed for a minimum of three months. Clinical records were reviewed to collect demographic, contextual, and clinical variables. Early complications and the need for re-splinting were recorded, and associations between selected variables and outcomes were analyzed. Results: Seventy-three patients (64.4% male; mean age 10.29 ± 2.99 years) and 127 traumatized teeth (98.4% permanent) were included. A predominance of school-based injuries was observed (52.1%). The most frequent injury types were subluxation (39.1%), avulsion (26.6%), and extrusion (16.4%). A longer interval between trauma and splint placement was associated with inflammatory root resorption (p = 0.011), although this finding should be interpreted with caution given the limited number of events. Mixed-dentition splints showed a higher likelihood of requiring re-splinting (OR = 12.23; 95% CI: 1.18–126.60); however, this estimate was imprecise and should be interpreted as an exploratory signal. Overall, 90.4% of patients completed treatment with a single splint. Conclusions: Within the limitations of this retrospective observational cohort, TTS showed satisfactory short-term clinical stability in pediatric traumatic dental injuries. Longer time between trauma and splint placement was associated with inflammatory root resorption, while mixed-dentition splints emerged as a potential signal of increased re-splinting. These findings are exploratory and hypothesis-generating and require confirmation in future studies.

Background/Objectives: Ankyloglossia diagnosis and management remain widely debated in dentistry, with variability reported in clinical decision-making and treatment approaches. Limited international evidence exists comparing how dental professionals diagnose and manage this condition in early childhood. This study aimed to compare the knowledge, diagnostic criteria, and clinical management of ankyloglossia among dental professionals in six countries and to assess whether shared diagnostic and management approaches exist for babies (≤6 months) and infants (>6 months). Methods: A multicountry cross-sectional study was conducted using a validated 27-item online questionnaire distributed between February 2023 and February 2025 to dental professionals in Spain, Italy, Portugal, Brazil, Ecuador, and Chile. Participants included paediatric dentists, oral surgeons, general dentists, and other dental specialists. Only fully completed questionnaires were analyzed. Primary outcomes included self-reported diagnostic practices, use of classification systems, and management strategies for ankyloglossia. Secondary outcomes included professional training, interdisciplinary collaboration, surgical techniques, and pain management practices. Results: A total of 1188 dental professionals participated. Overall, 80.7% reported routinely examining the lingual frenulum, while 42.4% used formal classification systems. Tongue mobility assessment was the most commonly reported diagnostic method, with significant variation across countries and professional groups (p < 0.001). Specific training in diagnosis was reported by 67.2% of participants, whereas 50.6% reported treatment training, with marked inter-country differences (p < 0.001). Surgical intervention was the most commonly reported management strategy (38.7%), particularly in babies ≤ 6 months, with frenotomy/frenulotomy being the predominant procedure. Considerable variability was observed in surgical techniques, pain management, and recommendations for adjunctive therapies. Conclusions: Substantial international variability exists in the diagnosis, classification, and management of ankyloglossia among dental professionals. These findings highlight gaps in training and the absence of standardized, evidence-based clinical guidelines, underscoring the need for consensus-driven protocols to support consistent and multidisciplinary clinical care.

Implant stability can be compromised by factors such as inadequate bone quality and infection, leading to potential implant failure. Ensuring implant stability and longevity is crucial for patient satisfaction and quality of life. In this multicenter, randomized, double-blind clinical trial, we assessed the impact of a bone bioactive liquid (BBL) on the Galaxy TS implant’s performance, stability, and osseointegration. We evaluated the impact stability, osseointegration, and pain levels using initial stability quotient (ISQ) measurements, CBCT scans, and pain assessment post-surgery. Surface analysis was performed using scanning electron microscopy (SEM) and atomic force microscopy (AFM). In vitro studies examined the BBL’s effects on dental pulp pluripotent stem cells’ (DPPSCs’) osteogenesis and inflammation modulation in human macrophages. All implants successfully osseointegrated, as demonstrated by the results of our clinical and histological studies. The BBL-treated implants showed significantly lower pain scores by day 7 (p < 0.00001) and improved stability by day 30 (ISQ > 62.00 ± 0.59, p < 8 × 10−7). By day 60, CBCT scans revealed an increased bone area ratio in BBL-treated implants. AFM images demonstrated the BBL’s softening and wettability effect on implant surfaces. Furthermore, the BBL promoted DPPSCs’ osteogenesis and modulated inflammatory markers in human primary macrophages. This study presents compelling clinical and biological evidence that BBL treatment improves Galaxy TS implant stability, reduces pain, and enhances bone formation, possibly through surface tension modulation and immunomodulatory effects. This advancement holds promise for enhancing patient outcomes and implant longevity.

Background: Oral surgery involves the diagnosis and surgical treatment of diseases affecting the soft and hard tissues of the oral cavity and encompasses a wide range of surgical interventions. The aim of this investigation was to study the characteristics and age-related diagnoses of these oral surgeries, as well as to describe the surgical procedures performed in a pediatric oral and maxillofacial surgery service. Methods: A descriptive, retrospective, observational, and relational study was conducted on children and adolescents aged from 0 to 22 years who were treated in a pediatric oral and maxillofacial surgery service at a children’s hospital. Results: We analyzed 1311 surgical interventions (51.4% were on boys and 48.6% on girls), consisting of 24.8% soft tissue surgeries, 65.9% bone and dental tissue surgeries, and 9.3% mixed tissue surgeries. The most common pathologies were tooth eruption disorders (65.9%), followed by ankyloglossia (20.5%). The most frequent treatment was wisdom teeth extraction (31.3%). A statistically significant association (p < 0.05) was found between surgical treatments and variables such as age, sex, tissue type, and biopsy. Conclusions: This study enhances our understanding of pediatric oral surgery, emphasizing that the most common pathology is altered tooth eruption, while the most frequent surgical intervention is the extraction of wisdom teeth at different stages of development.

This study aimed to describe Traumatic Dental Injuries (TDI) in a child population, with a discussion focused on the impact of non-clinical variables on TDI. A cross-sectional, descriptive, and relational study about TDI in deciduous dentition in a children's hospital was performed. A total of 166 patients were included, of which 51.8% were male and 48.2% were female. Subluxation was the most observed injury (37.5%), and high-severity lesions predominated (60.2%). Regarding non-clinical variables, 89.2% of the patients attended urgent care centers within 24 h, and 43.4% within the first 3 h. Pointed objects were the leading cause of TDI (47%). Most TDIs were concentrated between the ages of 2 and 4 (53.5%). Concerning the place of TDI occurrence, the school (41.6%) was associated with faster urgent dental care attendance, and the home (37.3%) was associated with TDI occurrence in children under 2 years of age. Previous TDI experience (24.1% of patients) did not generate differences in the time interval between the TDI and arrival at the hospital, compared with children without a TDI history. While the behavior of clinical variables agrees with the literature reviewed, several non-clinical variables show wide differences. There is a need to identify the non-clinical variables that can significantly interact with phenomena specific to the study population (social, demographic, and cultural). The study of these variables can be useful in applying health policies. In the group studied, the non-clinical data reveals the need to educate parents or guardians on the importance of timely care in TDI, the long-term consequences of traumatism affecting deciduous dentition, and the implication of the maturation of the child's motor skills in TDI.

Following surgery, healing within the oral cavity occurs in a hostile environment, and proper oral care and hygiene are required to accelerate recovery. The aim of the current study is to investigate and compare the bioreactivity characteristics of mouthwashes based on either chlorhexidine (CHX) or a novel bone bioactive liquid (BBL) in terms of oral healing within seven days application post-surgery. A randomized, double blind clinical trial was conducted in 81 patients, wherein the mouthwashes were applied twice a day for a period of 7 days. The visual analog scale (VAS) protocol was applied to determine pain index scores. Early wound healing index (EHI) score was determined for evaluating oral cavity healing progress. No adverse effects were observed using the mouthwashes, but CHX application resulted in stained teeth. Applications of both CHX and BBL were sufficient to reduce pain over a period of 7 days. However, the BBL group demonstrated a statistically significant reduction in VAS scores starting on day 4. The EHI scores were significantly higher in the BBL group compared with the CHX group, independent of tooth location. No differences in either VAS or EHI scores due to gender were observed. Compared with the commercially available CHX mouthwash, application of the BBL mouthwash reduced pain and accelerated oral cavity healing to a greater extent, suggesting it effectively improves the oral cavity microenvironment at the wound site in mediating soft tissue regeneration.

Aim:Tooth decay is the main oral pathology and a worldwide public health problem. The paediatrician is the first medical professional to assess and treat children. Therefore, it is important that they are well informed. The aim is to determine the level of dental knowledge of paediatricians practising in the public and private health sectors in Catalonia (Spain).Material and methods:Cross-sectional, descriptive, and analytical study of the basic dental knowledge of paediatricians through an anonymous and voluntary survey of 17 questions on prevention, trauma and dental cavities. The results are segmented based on professional experience, type of centre and whether it has a paediatric dentistry area.Results:A total of 129 paediatricians from Catalonia participated. Almost all paediatricians (86.82%) normally perform an oral examination in a routine visit; 31.8% refer the child to the paediatric dentist when the first permanent molars have erupted, and 41.9% indicate that toothpaste should contain a minimum of 1,000 ppm of fluoride. It is proven that paediatricians practising in the private sector have greater dental knowledge than those in the public sector (p = 0.019). Experience is not related to knowledge (p = 0.0691). The paediatricians who have a paediatric dentistry area in their workplace show greater knowledge (p = 0.046).Conclusion:Only half of the surveyed paediatricians follow the recommendations of paediatric societies on prevention aspects. In dental traumatology, professionals mostly follow the recommendations supported by the literature with high scientific evidence.

AIM:To determine the prevalence of ankyloglossia in newborns with breastfeeding problems and to assess the effectiveness of frenotomy in the maintenance of exclusive breastfeeding at 1 month, 3 months and 6 months in newborns at an Andorran Hospital.STUDY DESIGN:A descriptive, cross-sectional, population-based, retrospective study of newborns over a 5-year period (2016-2020) was performed. Nine medical history variables (presence or absence of ankyloglossia and type of frenulum, surgical intervention or not, first degree hereditary component, gender, Rh and blood group, type of breastfeeding, causes of cessation and duration of breastfeeding) related to perinatal and feeding history were collected confidentially and anonymously. The Coryllos classification was used for the diagnosis of ankyloglossia. Descriptive analysis of the data, Chi-square test and prevalence ratios were calculated.RESULTS:A total of 2333 newborns were included in the study (50.02% males and 49.98% females). The prevalence of ankyloglossia was 7.84% (n = 183). Of the infants examined, 136 underwent lingual frenotomy. The number of infants who maintained exclusive breastfeeding, both surgically and non-surgically treated, was no statistically significant differences at 1 month (p = 0.65), 3 months (p = 0.61) and 6 months (p = 0.49).CONCLUSIONS:Lingual frenotomy was only performed on patients with ankyloglossia associated with ineffective suction that causes BF difficulties. The realization or not of frenotomy was not a determining factor for the maintenance of breastfeeding at 1 month, 3 months and 6 months. On the contrary, it was a determining factor for the prolongation of mixed feeding. Ankyloglossia related to breastfeeding difficulties should be treated by a multidisciplinary team.

Background: Bioactive chemical surface modifications improve the wettability and osseointegration properties of titanium implants in both animals and humans. The objective of this animal study was to investigate and compare the bioreactivity characteristics of titanium implants (BLT) pre-treated with a novel bone bioactive liquid (BBL) and the commercially available BLT-SLA active. Methods: Forty BLT-SLA titanium implants were placed in in four foxhound dogs. Animals were divided into two groups (n = 20): test (BLT-SLA pre-treated with BBL) and control (BLT-SLA active) implants. The implants were inserted in the post extraction sockets. After 8 and 12 weeks, the animals were sacrificed, and mandibles were extracted, containing the implants and the surrounding soft and hard tissues. Bone-to-implant contact (BIC), inter-thread bone area percentage (ITBA), soft tissue, and crestal bone loss were evaluated by histology and histomorphometry. Results: All animals were healthy with no implant loss or inflammation symptoms. All implants were clinically and histologically osseo-integrated. Relative to control groups, test implants demonstrated a significant 1.5- and 1.7-fold increase in BIC and ITBA values, respectively, at both assessment intervals. Crestal bone loss was also significantly reduced in the test group, as compared with controls, at week 8 in both the buccal crests (0.47 ± 0.32 vs 0.98 ± 0.51 mm, p < 0.05) and lingual crests (0.39* ± 0.3 vs. 0.89 ± 0.41 mm, p < 0.05). At week 12, a pronounced crestal bone loss improvement was observed in the test group (buccal, 0.41 ± 0.29 mm and lingual, 0.54 ± 0.23 mm). Tissue thickness showed comparable values at both the buccal and lingual regions and was significantly improved in the studied groups (0.82–0.92 mm vs. 33–48 mm in the control group). Conclusions: Relative to the commercially available BLT-SLA active implants, BLT-SLA pre-treated with BBL showed improved histological and histomorphometric characteristics indicating a reduced titanium surface roughness and improved wettability, promoting healing and soft and hard tissue regeneration at the implant site.

Liver diseases are major causes of morbidity and mortality. Dental pulp pluripotent-like stem cells (DPPSCs) are of a considerable promise in tissue engineering and regenerative medicine as a new source of tissue-specific cells; therefore, this study is aimed at demonstrating their ability to generate functional hepatocyte-like cells in vitro. Cells were differentiated on a collagen scaffold in serum-free media supplemented with growth factors and cytokines to recapitulate liver development. At day 5, the differentiated DPPSC cells expressed the endodermal markers FOXA1 and FOXA2. Then, the cells were derived into the hepatic lineage generating hepatocyte-like cells. In addition to the associated morphological changes, the cells expressed the hepatic genes HNF6 and AFP. The terminally differentiated hepatocyte-like cells expressed the liver functional proteins albumin and CYP3A4. In this study, we report an efficient serum-free protocol to differentiate DPPSCs into functional hepatocyte-like cells. Our approach promotes the use of DPPSCs as a new source of adult stem cells for prospective use in liver regenerative medicine.

AIM The enamel defects of Molar-Incisor Hypomineralisation (MIH) share clinical characteristics with hypomineralised second primary molars (HSPM) and hypomineralised primary canines (HPC). The main objective of this study is to determine the prevalence of these entities in a population of patients in a hospital dentistry service. The secondary objectives are to know the number and distribution of lesions, classify them according to their degree of severity and to know which dental surfaces are most affected. METHODS A cross-sectional and observational prevalence study was carried out over a 32-day period, guided by the diagnostic criteria of the European Academy of Paediatric Dentistry (EAPD) together with the descriptive study of the lesions. Healthy patients between 30-42 months and who had all erupted teeth were included. RESULTS Out of a total of 153 patients, 29 presented HSPM (18.95%) and 17 HPC (11.11%). Check-ups were made on 116 second primary molars (SPM) and 116 primary canines (PC), obtaining 81 HSPM (69.82%) and 31 HPC (26.72%). The lesions observed were mild in 60 molars (74.07%) and in 27 canines (87.09%). As for the 405 surfaces checked, 168 showed HSPM (41.48%) and 43 HPC (10.61%). CONCLUSIONS The prevalence of HSPM and HPC varies depending on the population studied. It was observed that SPM were affected more often than PC, with the occlusal and buccal surfaces being the most affected, and the majority of the lesions presenting a low degree of severity.

Purpose: The aim of this study is to evaluate the effectiveness of gel topical anaesthesia in second surgeries of dental implants to find the cover screw which has been submerged; to check if there are significant differences in the perception of pain between the different treated areas of the oral cavity, as well as to study the thickness and the type of oral mucosa in which the gel topical anaesthesia is effective. Material and Methods: 13 partially and completely edentulous patients with 30 implants in total were included in the study. Those submerged dental implants whose cover screw was not submerged in a depth higher than 2-4 mm were selected. In the event of the gel topical anaesthesia not being effective, reinforcement with conventional infiltrative anaesthesia was made. Pain was measured with Visual Analogue Scales (VAS), and the gum thickness with periodontal probe. Results: The 66.67% of the sample needed reinforcement through conventional anaesthetic infiltration. No statistically significant differences were found in the comparison of pain with different gum thickness, implant localization in the oral cavity, although a higher feeling of pain was actually observed in those patients who were firstly subjected to a second-stage surgery (p<0,05). Conclusions: The use of gel topical anaesthesia cannot be considered as the sole treatment to eliminate the feeling of pain, but as a coadjuvant to infiltrative anaesthesia. No significant differences have been found between the different treated areas of the oral cavity, nor in the thickness or type of oral mucosa.

The aim of this study was to investigate the effect of a probiotic in preventing infections after third molar surgery. Thirty-eight patients were consecutively enrolled to a double-blind randomised placebo-controlled trial. Patients were asked to take one tablet two times a day containing a mixture of Levilactobacillus brevis CECT7480 (KABP-052) and Lactoplantibacillus plantarum CECT7481 (KABP-051) or placebo for the first post-intervention week. The primary outcome was the postoperative infection rate. Secondary outcomes included swelling, eating difficulties and postoperative pain recorded by the patient using a visual analogue scale (VAS) during the first postoperative week. No statistically significant difference in the infection rate between the groups was found; with only three cases of infections reported (one in the probiotic group and two in the placebo group) on the first week. Compared to placebo, treatment with the probiotic showed a significantly higher reduction in pain and eating difficulties scores at 5, 6 and 7 days post-surgery. Swelling values were not significantly different between the groups at any time point. The findings of this pilot study justify a larger study to clarify the possible role of these bacterial strains on the post-operative pain management following third molar surgery.

OBJECTIVESTo evaluate the immediate and 9-month results of blended versus standard training in basic life support and the use of an automatic external defibrillator (BLS/AED).MATERIAL AND METHODSRandomized trial comparing the results of standard BLS/AED training to blended training. The control group received 4 hours of standard instruction from a trainer and the experimental blended-training group received 2 hours of virtual training and 2 hours of in-person instruction.RESULTSEighty-nine students participated, 45 in the control group and 44 in the experimental group. The controls achieved better mean (SD) knowledge scores immediately after training (8.6 [0.9] vs 8.0 [1.14] in the experimental group, P=.013). The blended training group scored better on certain skill markers (hands-off time in seconds and compressions followed by complete chest recoil). Participant knowledge had decreased at 9 months without significant between-group differences. Overall, retention fell from a score of 8.31 (1.1) to 6.04 (1.6) (P=.001) in 9 months and the loss was similar in the 2 groups. No differences in practical skills between the groups were observed at the end of the course or 9 months later.CONCLUSIONThe blended training method led to better results on some skill items.

Osteogenesis Imperfecta (OI) is a rare autosomal dominant connective tissue disorder in wich, the bone quality and density is affected. OI includes some metabolic disorders and have a wide range of clinical presentations. In Osteogenesis Imperfecta bone has a very low density and it is a disorder currently treated with bisphosphonates. Quality and quantity of bone is important for establishment of osseointegration in dental implants. There are few reported cases in the literature. This is a case report of a 61 year-old man with grade IV OI, rehabilitated with implant-supported fixed prostheses in the posterior right and left mandible, whithout bone grafts. At the 4-year follow-up, clinical and imaging study showed no evidence of pathology in the peri-implant tissues. The final outcome is a correct occlusion and masticatory function. This case shows that dental implants may be a treatment option in this patients, however there is still quite limited scientific evidence. Key words:Osteogenesis imperfecta, osteoporotic bone, dental implants, bone fragility, bisphosphonates, drilling technique.

La limitación de la movilidad lingual en neonatos puede ocasionar problemas en la lactancia, entre ellos: dolor-grietas-mastitis en la madre, mal progreso de peso del neonato y duración excesivamente larga de las tomas. El objetivo de este trabajo es evaluar la efectividad de los tratamientos realizados en los pacientes con anquiloglosia y trastornos de succión. Estudio descriptivo preliminar de la efectividad del circuito establecido entre los servicios de Cirugía Oral y Maxilofacial, Logopedia y Rehabilitación Orofacial y Lactancia Materna para el tratamiento de los pacientes que acuden con problemas de lactancia materna y se les diagnostica anquiloglosia. Se trató a 61 pacientes de edades entre 0 y 6 meses con anquiloglosia asociada a problemas clínicos relacionados con la lactancia: 20 niñas (32.8%) y 41 niños (67.2%). Se establecieron 3 grupos según el tratamiento realizado: grupo 1 (n = 6) únicamente las sesiones de lactancia materna (SLM), grupo 2 (n = 19) terapia miofuncional (TMF) y asesoramiento en SLM, y grupo 3 (n = 36) frenotomía y siguieron TMF y asesoramiento de SLM. La anquiloglosia tipo iii es el frenillo lingual más frecuente (57.4%). En el total de la muestra se observaron mejorías en los parámetros que valoran la efectividad y el confort de la lactancia materna. Mejorar la succión es posible; se recomienda estimular la succión con terapia miofuncional antes y después de la frenotomía, y también en aquellos casos en los que no será necesaria la cirugía. The limitation of lingual mobility in newborns can cause problems in lactation. Among these problems are, soreness, cracked nipples or mastitis in the mother, poor weight gain of the newborn, and an excessively prolonged period of time in each breastfeed. The aim of this study is evaluate the effectiveness of the treatment received by the newborns with breastfeeding problems and ankyloglossia. A preliminary study of the effectiveness of the circuit established between the Oral and Maxillofacial Surgery, Speech Therapy and Orofacial Rehabilitation and the Breastfeeding Department to treat patients that attended the hospital with breastfeeding problems and were diagnosed with ankyloglossia. A total of 61 patients with ages between 0 and 6 months had ankyloglossia were seen due to clinical problems related to breastfeeding. Of these, 20 (32.8%) were girls and 41 (67.2%) were boys. Three groups were established in accordance with the treatment carried out: group 1 (n = 6) solely from the Breastfeeding Sessions (BFS), group 2 (n = 19) Myofunctional Therapy (MFT) and BFS, and group 3 (n = 36) Frenotomy, followed by MFT and BFS. Ankyloglossia type 3 was the most frequent lingual frenulum (57.4%). From the total sample, improvements were observed in the parameters that assessed the effectiveness and comfort of breastfeeding. Improving breastfeeding is possible, and in some cases, surgery should not be necessary. If surgery is required, it is recommended to stimulate suction before and after the frenotomy with myofunctional therapy.
