Introduction: Dental age estimation using third molars is a reliable method for estimating the age of individuals. Recently, magnetic resonance imaging (MRI) of the head and neck has been found to be applicable for age estimation of third molar teeth. In the present study, we aimed to apply the Modified Demirjian method of age estimation to magnetic resonance (MR) image sections for dental age estimation by determining the mineralization patterns of the maxillary third molars.

Methods: MRI scans of the patients were performed using SIGNA™ 3.0Tesla MRI GE Healthcare (Chicago, USA) with a moving, multifunctional coil. Two expert radiologists with more than three years of experience independently analyzed the image sections using the open-source Digital Imaging and Communications in Medicine (DICOM) viewer software. The age and sex of the patients whose images were included in the study were recorded using a specially designed proforma. The stage of development of the maxillary third molars was determined using the modified Demirjian method. Inter observer agreement was calculated using the intra class correlation coefficient. Simple linear regression analysis was used to predict the actual age at the third molar development stage.

Results: There was excellent agreement between observers (ICC =0.99 (95% CI = 0.98-0.99)). There was also a significant association between the maxillary third molar tooth development stage and chronological age of the individual (P=0.001; B=1.54; 95% CI = 0.71-2.37).

Discussion: The findings from the present study establish that the Modified Demirjian method can also be reliably applied for dental age assessment in MR sections.

Background/objective: Understanding the patterns and reasons behind the extraction of children's primary teeth is crucial for improving oral health outcomes. This retrospective investigation aimed to discern the patterns and factors contributing to primary tooth extraction among pediatric patients aged 3 to 5 years treated at the Pediatric Surgery Department of the National Curative and Specialized Stomatology Hospital in Kabul, Afghanistan.

Materials and methods: Between January and May 2023, we conducted an extensive review of dental records, focusing on patients aged 3 to 5 years who had undergone primary tooth extraction. Data were collected on patients' age, gender, specif tooth extracted, and reasons for tooth extraction. Statistical analysis was performed using SPSS Statistics version 25.

Results: Among 150 subjects reviewed, 53.3% were male. Primary first molars were the most commonly extracted teeth (29.3%). Dental caries was the leading cause of extraction (50%), followed by periodontitis (31.3%) and root resorption (18.7%). Mandibular extractions (58.6%) were more frequent than maxillary extractions (41.4%). No significant differences were found based on age or tooth type. Weak correlations were observed between specific tooth extractions, age, and etiology.

Conclusion: This study reveals a higher frequency of extractions in older children, primarily due to dental caries, periodontitis, and root resorption, with a slight male predominance. While no significant differences were noted in extraction patterns based on age or tooth type, understanding these trends is essential for improving pediatric dental care.

This integrative literature review evaluates the effectiveness of power toothbrushes (PTBs) compared to manual toothbrushes (MTBs) across various populations, focusing on plaque removal, gingival health, calculus reduction, and stain removal. PTBs equipped with advanced technologies such as oscillating-rotating and high-frequency sonic mechanisms have been examined for their potential to enhance oral hygiene. Special attention is given to vulnerable groups, including the elderly and individuals with intellectual disabilities, to assess how PTBs meet their specific oral health needs. A comprehensive literature search was conducted in databases including PubMed, Cochrane Library, Embase, and Google Scholar using keywords such as "power toothbrush", "electric toothbrush", "manual toothbrush", "plaque removal", "gingivitis", "calculus", "dental stains", "oral hygiene", "elderly", and "intellectual disabilities". Studies published between 2000 and 2024 were selected based on their relevance to the PTB and MTB comparison, with an emphasis on outcomes related to oral hygiene efficacy. As this review is narrative rather than systematic, it focuses on synthesizing existing knowledge without applying strict inclusion or exclusion criteria. The results indicate that PTBs generally outperform MTBs in reducing plaque, gingivitis, and stains, though the benefits for special populations are less pronounced but still significant. However, practical issues such as user experience and mechanical reliability of PTBs warrant further investigation. In conclusion, this review enhances the understanding of PTB effectiveness, guides consumer choices, and informs future technological advancements in dental care practices.

Background: Whether there is a relationship between blood group and the likelihood of acquiring oral diseases. Therefore, the present study investigated the potential association between ABO blood groups and various dental conditions, including dental caries, gingivitis, malocclusion, and impacted teeth, in Saudi adults aged 18 years and older.

Methods: A cross-sectional study was conducted on 300 participants who met the inclusion criteria. Data collection included assessment of dental caries status using the decayed missing filled teeth (DMFT) and decayed missing filled surfaces (DMFS) indices, evaluation of gingivitis using the Gingival Index, classification of malocclusion according to Angle's classification system, and recording the presence or absence of impacted teeth.

Results: The AB blood group had the significantly highest mean DMFS score (8.58±6.63), while the O blood group had the lowest mean DMFS score (6.37±4.43). Additionally, blood group O showed a slightly higher prevalence of gingivitis (51.92%) than the other blood groups. Blood group A demonstrated a higher prevalence of both Class II (34.2%) and Class III (19%) malocclusions, with statistically significant differences. Regarding impacted teeth, blood group AB (48.8%) had the highest occurrence.

Conclusion: There exists an association between oral disease and ABO blood group in Saudi adults. The results of this study indicate that individuals with specific blood types may be more prone to oral diseases, which can aid in the early diagnosis and prevention of these conditions.

Background: Mobile technology health application (mobile Apps) can assist people manage their health and wellness, encourage healthy lifestyles, and provide valuable information whenever necessary.

Objective: This study aimed to evaluate the feasibility and acceptability of a mobile App for oral health education among adults in Rwanda.

Methods: This was a descriptive cross-sectional study. A total of 111 adult participants evaluated the acceptability and feasibility of the BrushDJ mobile App after using it for three months. At the end of this period, an online survey was conducted using a structured questionnaire consisting of questions on demographics, habitual oral health, assessing acceptability, and assessing the feasibility of the mobile App. Descriptive statistics were performed to analyse demographic characteristics, the feasibility and acceptability of the mobile App. Bivariate analysis using the Chi-square test was performed to detect significant associations amongst the variables.

Results: The response rate was 81% (n=90) of 111 participants who took part in the study, with the majority of participants 44.44% (n=40) aged between 18 and 27 years old. Just over half of the participants were male 51.11% (n=46). The mobile App was found to be highly acceptable (87.78%; n=79) and considered highly feasible (84.44%; n=76) by most of the participants. The differences in acceptability and feasibility across education levels were statistically significant (p=0.000 for acceptability and p=0.038 for feasibility).

Conclusion: The study revealed that the mobile App for oral health education (BrushDJ) was highly acceptable and feasible among the participants. The mobile App had a user-friendly interface and comprehensive guidance on oral hygiene procedures facilitated by its diverse and well-integrated functions.

Introduction: Root canal retreatment is carried out in cases where previous endodontic therapies failed and involves the removal of root canal filling materials, followed by cleaning, shaping, and obturating of the canals.

Aims: : The objective of this study was to collect information regarding attitudes, methods, and materials employed during the non-surgical endodontic retreatment (NSER) by general dentists working in Sousse Governorate, Tunisia.

Materials and methods: A descriptive cross-sectional survey was conducted among 147 general dentists working in the Sousse Governorate, Tunisia, from May to November 2021. Data were collected by sending a structured questionnaire to the dental practitioners through email. All the data were analyzed by using the SPSS 10 computer software.

Results: A total of 96 dentists responded to this survey. The response rate was 63.5%, with a female predominance (53.2.3%). 81.2% of the respondents performed at least one non-surgical endodontic retreatment (NSER) weekly. Our study revealed that the mandibular first molar is the tooth that most often requires endodontic retreatment (83.5%). Half of the participants never used the rubber dam during this procedure. Moreover, the majority of respondents (61.9%) simultaneously used manual files and rotary nickel-titanium instruments for root canal desobturation. Most of the dentists (69.57%) systematically use solvents during root canal desobturation.

Conclusion: Our survey highlights that the majority of general dentists have adequate knowledge about endodontic retreatment. Nevertheless, dentists are yet to start the application of these newer strategies towards the management of endodontic failures.

Background: Treatment of Molar-incisor hypomineralisation (MIH) poses significant challenges for pediatric dentists due to its varied clinical manifestations and treatment needs. Understanding and evaluating different treatment options can improve patient outcomes. This study aimed to analyze available evidence on treatment options for restoring MIH-affected young permanent teeth.

Methods: This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. A systematic literature search was conducted using Scopus, PubMed, and Science Direct databases, covering publications from 2014 to 2024. The search focused on therapies for young permanent teeth with MIH in children, employing predefined keywords and the Population, Concept, and Context framework.

Results: A total of 20 studies were included from Turkiye, Brazil, Syria, Germany, Egypt, and India. Thirteen articles examined first molars, five focused on incisors, and two covered both. The population studied ranged from 6 to 18 years old, involving up to 281 children and between 30 to 326 teeth. The study provides insights into various management and treatment approaches for MIH-affected teeth, along with the effectiveness and long-term stability of different methods and materials.

Conclusion: Materials such as resin infiltration, SDF, HVGI, full metal crowns, SSC, lithium disilicate, zirconia crowns, and CAD/CAM ceramic restorations offer greater longevity and require less retreatment in managing MIH-affected teeth.

Aim: Root canal treatment (RCT) is a common procedure practiced daily by dentists worldwide. The current systematic review aimed to evaluate and compare clinical studies on the quality of root canal fillings (RCFs) carried out by dentists with different levels of experience conducted worldwide with those conducted specifically in Saudi Arabia (SA).

Materials and methods: A full literature search was conducted in Clarivate Analytics' Web of Science, Elsevier's Scopus, Embase, CINHAL, and PubMed, without a restriction to studies published before January 2015. Also, a manual search was carried out by checking papers that may have been missed during the electronic search. The following keywords were used: [(quality of root canal filling(s)) OR (quality of root canal obturation)) and dental practitioners as (general dental practitioners; final year students; endodontist; specialist) AND (root canal obturation) OR (endodontic treatment)]. Parameters of the quality of RCFs, such as length, density, and taper, were assessed and counted.

Results: A total of 13 worldwide and nine SA studies were included in this review, published between 2015 and 2023. Molars were the most treated teeth, at 42.3% and 40.2% for the worldwide and SA studies, respectively. Cases treated by final year students had the highest percentage, at 60.0% for both study groups. The percentages of acceptable quality, with regard to the length, density, and taper of RCFs, were 70.9%, 77.6%, and 84.3%, and 73.2%, 64.6%, and 67.8% for the worldwide and SA studies, respectively.

Conclusion: The overall acceptable quality of RCFs was marginally higher in worldwide studies than in SA studies. Both prevalences can be considered as good, which indicates that the quality of RCFs is moving in the right direction.

Hereditary gingival fibromatosis (HGF) is an uncommon genetic condition marked by gradual and progressive overgrowth of fibrous tissue in the gums, which is benign in nature. It is a genetic disorder inherited in an autosomal dominant pattern, known for its considerable genetic diversity. The marginal, attached, and interdental gingivae are affected by this condition. The affected area appears pink, does not bleed easily, and exhibits a firm, fibrotic texture. Additionally, it displays a hard, widespread nodular growth that is smooth to stippled and has little bleeding tendency. Nevertheless, in certain instances, the enlargement may feel so dense and firm that it resembles bone upon palpation. Accordingly, esthetics and functions related to a healthy gingiva is also affected. The choice of treatment modality often depends on factors such as the severity of gingival overgrowth, available resources, and patient-specific considerations. Laser techniques and electrosurgery have emerged as valuable options, providing benefits like reduced discomfort and enhanced precision. However, traditional surgical methods remain highly effective, particularly when advanced technologies are not available. This article reports on three cases of hereditary gingival fibromatosis (HGF) treated with conventional gingivectomy, flap procedures, and resective osseous surgery (osteoplasty and osteotomy). The aim is to support the efficacy of these interventions in addressing patient complaints and preparing the groundwork for managing additional issues, such as speech and mastication difficulties, delayed eruption of permanent teeth, and malocclusion. The surgical treatment led to significant improvements: masticatory function was markedly enhanced, aesthetic outcomes were notably better, and oral hygiene significantly improved. Additionally, the procedures created favorable conditions for future treatments, including orthodontics, implants, or prosthetics, by providing a more manageable and functional oral environment.
