Aim: To evaluate and compare the sorption and solubility of two different core buildup materials in different pH media for periods of one day, one week, and one month. Materials and method: Sixty samples were prepared and divided into Group A (30 resin -based samples) Group B (30 glass ionomer cement (GIC)-based samples). The sorption and solubility of the different materials were calculated by weighing the samples before and after desiccation and media immersion periods of one day, one week, and one month. Groups were compared using the Mann -Whitney U test, for different media, the intragroup significance of the mean difference was performed using the Friedmann test and Wilcoxon signed rank test at a significance level of p<0.05. Results: After immersion for different time periods, the resin -based core buildup material (Core X flow) showed less sorption and solubility as compared to the glass ionomer-based core buildup material (Secure Core Z) for all time periods, with a significant difference seen for a time period of one week and one month and being nonsignificant for a time period of one day. Conclusion: Core X flow had lower sorption and solubility values when compared to Secure Core Z, as the International Organization for Standardization (ISO) 4049 standards, except for a one -month time period in alkaline media.

Background Radiopacity is a critical property for root canal sealers as it allows for the assessment of the material's placement and quality within the root canal system on radiographic images. The study aimed to evaluate the radiopacity of calcium silicate-based and resin-based materials using direct digital radiography, employing an aluminium step wedge according to American National Standards Institute/International Organization for Standardization (ANSI/ISO) standard protocols for testing the radiopacity of root canal sealers. This study seeks to determine the effectiveness of these materials in meeting the required standards for clinical use. Methodology The materials tested were AH Plus, Apexit Plus, Biodentine and MTA Fillapex in circular disc form and radiographed alongside the aluminium step wedge using direct digital radiography to determine the radiopacity using grey-pixel values. All the materials, viz., AH Plus, Apexit Plus, Biodentine and MTA Fillapex were found satisfactorily radiopaque and met the minimum radiopacity standard, that is, minimum 3mm of aluminium recommended by ANSI/American Dental Association (ADA) Specification No. 57. Results AH Plus exhibited the highest radiopacity with values of 222.54 mm Al Eq (isodensity) and 220.88 mm Al Eq (densitometric), significantly surpassing Apexit Plus, Fillapex and Biodentine (p < 0.001). Apexit Plus and Fillapex showed no significant difference between them (p = 0.238), but both were significantly higher than Biodentine (p < 0.001). Biodentine had the lowest radiopacity among all the sealers tested. Conclusion All the tested materials met the ANSI/ADA minimum radiopacity standard, demonstrating their suitability for clinical use. The materials varied in their levels of radiopacity, demonstrating that they are adequately visible on radiographic images for effective assessment in root canal treatments.

Background Removing gutta-percha manually can be a challenging task, especially when addressing densely packed root-filling material, particularly in cases where resin-based sealers are employed for obturation. The use of nickel-titanium (NiTi) rotary instruments not only effectively shapes the root canal but also efficiently removes the endodontic filling from the curved canal during retreatment. Hence, incorporating rotary NiTi instruments in retreatment cases can alleviate fatigue for both patients and operators. Objectives This study aims to compare the efficacy of Neo-Endo retreatment files, R-Endo retreatment files, and K and H files in the removal of endodontic filling material. Additionally, the remnants of gutta-percha in root canals are evaluated using cone beam computed tomography (CBCT). Materials and methods A total of 60 extracted first maxillary molar teeth were selected for this study. Canal preparation was conducted using the step-back method up to an apical size of 40 K-file. The obturation process involved the use of gutta-percha points and AH Plus sealer in a lateral compaction technique. Post-operative CBCT scans were taken. The samples were randomly divided according to the retreatment files used: group I included Neo-Endo retreatment files, group II included R-Endo retreatment files, and group III included conventional K-files and Hedstroem files (H-Files). The retreatment procedure was considered complete when the last instrument easily reached the working-length range and was physically clean. A stopwatch was used to record the time taken by each file to remove the obturating material. T1 represented the total time (including irrigation and change of file) required to reach the apex, while T2 indicated the complete removal of materials from the canal with the last instrument. The overall time recorded (TT) was calculated as T1 + T2. The removal process was analyzed with CBCT scans. Results The Neo-Endo retreatment files removed the filling materials better and more quickly than the other files. Conclusions Despite the presence of residual filling material in all samples, the Neo-Endo retreatment files left the least amount of residual filling material and achieved the shortest completion time.

Background: Tobacco use poses severe health risks globally, affecting both young people and adults. It is highly addictive and a major contributor to various diseases, including cancer. This research at Teerthanker Mahaveer Dental College and Research Centre (TMDC and RC), Moradabad, focused on participants aged 35–44, highlighting the urgent need to address tobacco-related issues for public health and economic well-being. Aim: This study assesses the occurrence of smokers and smokeless tobacco and analyzes its correlation with the oral health-related quality of life (OHRQoL) among participants. Materials and Methods: A prevalence study was substantiated at TMDC and RC, Moradabad, involving 640 participants aged between 35 and 44 years. Informed assent was obtained from all participants. Sociodemographic information was collected, and their oral mucous lesions were assessed using the World Health Organization form. In addition, participants completed a validated Hindi version of the Oral Health Impact Profile-14 questionnaire to evaluate their OHRQoL. Results: The study revealed a higher prevalence of tobacco usage among males compared to females. Furthermore, the prevalence of smoking was established to be greater than that of smokeless tobacco. Consequently, a statistically apparent association was recognized between smokers and their OHRQoL, as well as between users of smokeless tobacco and their OHRQoL. However, no association was established between smokers, smokeless tobacco users, and OHRQoL when considering the significance value. Conclusion: The study indicates that individuals aged 35–44 years who use either smoked or smokeless tobacco experience similar impacts on their OHRQoL. Encouraging regular dental examinations, facilitating access to tobacco cessation programs, and extending support for individuals to sustain tobacco-free lifestyles are indispensable strategies for amplifying oral health outcomes besides the overall quality of life among individuals aged 35–44.

Objective: It is crucial to understand how individuals perceive the impact of oral disorders and the treatment associated with or received for those disorders on their quality of life. A relatively new but quickly spreading concept of oral health-related quality of life (OHRQoL) that notably affects three fields, clinical dental practice, dental research, and dental education makes it feasible to figure out the relationship between oral health and its impact on the quality of life of an individual. OHRQoL can be measured in various ways; the most well-liked method uses a multiple-item questionnaire. There haven't been any prior attempts to compare the effects of various invasive and non-invasive dental therapies on OHRQoL, even though few studies have been conducted to evaluate the OHRQoL among patients undergoing independent dental procedures. Such a comparison would aid in our understanding of not only how various dental conditions affect OHRQoL, but also whether or not a patient's OHRQoL has improved as a result of various therapies for these diseases.Method: A longitudinal study was conducted on patients receiving invasive and non-invasive dental treatment at Teerthanker Mahaveer Dental College and Research Centre, Moradabad. A two-part questionnaire, the first part of which consists of questions related to the demographic details of the patient and the second part consisting of a set of 14 questions of the oral health impact profile (OHIP)-14 for assessing the OHRQoL, was used in the study. Patients' baseline OHRQoL was assessed before the commencement of any treatment by the interview method and follow-up OHRQoL was assessed three days, seven days, one month, and six months post-treatment telephonically. The OHIP-14 contains 14 items on the frequency of adverse impacts caused by oral conditions and the patients were asked to rate each item on a 5-point Likert scale as 0=never; 1=hardly ever; 2=occasionally; 3=fairly often; 4=very often.Results: The results obtained after compiling and analyzing the data from a total sample of 400 indicate that the mean difference in the OHIP score at different time intervals between the groups who undertook invasive and non-invasive treatment was significant as the p-value was less than 0.05. In addition, it was observed that the mean difference at baseline was statistically significant in the invasive and non-invasive groups as the p-value is less than 0.05. At the domain level, the mean score at each domain was higher in the invasive group as compared to the non-invasive treatment group after three days and seven days of treatment. The mean difference between the group treated with invasive treatment on day three and the group treated with non-invasive treatment on day seven was statistically significant as the p-value is less than 0.05. The mean score was high in the invasive group as compared to the non-invasive group after one month and six months of treatment.Conclusion: The present study was conducted to assess dental treatment's impact on oral health-related quality of life in patients attending Teerthanker Mahaveer Dental College and Research Centre, Moradabad. Results from this study indicated that both types of treatments either invasive or non-invasive have significantly influenced the OHRQoL. Post-treatment OHRQoL improved at different intervals after receiving either treatment.
