Their prevalence varies by population, and early diagnosis is essential for comprehensive treatment planning. This study aimed to determine the prevalence and distribution of tooth number anomalies among paediatric patients aged 9-15 years in Aydın province, Türkiye.Materials and methods: This retrospective study evaluated panoramic radiographs of children who presented to the Department of Paediatric Dentistry at Aydın Adnan Menderes University between December 2013 and July 2022. A total of 8,647 radiographs meeting the inclusion criteria were analysed. Hypodontia, hyperdontia, and hypohyperdontia were recorded.Results: Tooth number anomalies were detected in 935 patients (10.8%). Hypodontia was the most prevalent anomaly (8.8%), followed by hyperdontia (1.9%) and hypohyperdontia (0.2%). Females showed a significantly higher prevalence of hypodontia ( P < 0.05), while no sex-related differences were found for hyperdontia or hypohyperdontia. A total of 1,475 missing teeth were identified, with mandibular second premolars being the most frequently absent. Among the 239 supernumerary teeth detected, the maxillary anterior region was the most commonly affected. Most patients with tooth number anomalies exhibited no additional dental anomalies; pegged laterals (3.3%) and taurodontism (0.3%) were observed only in hypodontia cases.Conclusion: Tooth number anomalies are relatively common among children in Aydın, with hypodontia representing the predominant condition. These findings underscore the importance of early detection and timely management to prevent functional and aesthetic complications. Further large-scale and genetic studies are needed to clarify etiological patterns and regional variations.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":"37 1","pages":"66-70"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148301495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, microbe-derived nanomaterials offer promising, broad-spectrum alternatives to synthetic drugs. This study aims to biosynthesize eco-friendly zinc oxide nanoparticles (ZnONPs) by a marine actinobacterium Streptomyces rochei and further characterize and ascertain its antibacterial and antibiofilm activities against the oral pathogen Streptococcus mutans .Materials and methods: ZnONPs were synthesised using S. rochei and characterised through spectroscopical analysis. Antibacterial activity was assessed using well-diffusion and multi-well plate assays. Biofilm inhibitory activity was determined using crystal violet assay and validated by microscopy.Results: ZnONPs showed Ultraviolet - Visible Spectroscopy (UV-Vis) peaks at 364 nm. Fourier Transform - Infrared Spectroscopy (FT-IR) results revealed the interaction of possible functional groups associated with the stability and surface chemistry of the nanoparticle. Field Emission - Scanning Electron Microscope (FE-SEM) results showed the morphology of ZnONPs was irregular and flaky, with an average grain size of 55.04 nm. ZnONPs exhibited profound antibacterial activity (Halo: 17.9 mm) with minimal bacteriostatic (50 μg/ml) and bactericidal (100 μg/ml) values. Biofilm inhibitory effect of ZnONPs inferred a substantial ( P < 0.05) reduction in a dose-dependent manner against S. mutans (24%-96%). Crystal violet and Confocal Laser Scanning Microscopic (CLSM) visuals manifested the distorted biofilm architecture of S. mutans .Conclusion: This novel approach underscores a sustainable method for synthesising ZnONPs and suggests that it could be effectively used as nano-antibiotics by coating the surface of dental implants.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"77-81"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147716704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine the prevalence and factors associated with tooth wear among 800 cement factory workers in Durg, Chhattisgarh, to inform the planning of preventive oral health services.Materials and methods: A cross-sectional study was conducted among workers with at least 1 year of experience. Data on demographics, work history, and department were collected. Tooth wear was assessed using the tooth wear index (TWI), with statistical analysis performed via Kruskal-Wallis H and Mann-Whitney U tests.Results: The mean age of participants was 32.71 ± 8.33 years. Cement mill workers had the highest prevalence of tooth wear with a mean TWI score for Score 1 (8.00 ± 3.57). Those with over 10 years of experience had significantly higher total TWI scores than those with less than 10 years for all categories of workers ( P < 0.001). Mean tooth wear scores were significantly lower among protective mask users than non-users, particularly with Score 1 and 2 ( P < 0.001).Conclusion: Prolonged occupational exposure is associated with more severe grades of tooth wear, indicating the accumulative risk for poor dental health in cement factories. These results underline the importance of appropriate improved occupational safety and health measures such as routine dental examinations and the provision of personal protective equipment such as masks in the workplace for the well-being of employees. The results would be able to provide evidence for the decision-making and prevention programs toward raising awareness of occupational oral health among workers.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":"37 1","pages":"29-33"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148301468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Group I included 16 early mixed dentition patients (age 7-9 years); Group II included 16 late mixed dentition patients (age 11-13 years). All patients received a palatal miniplate with a face mask. Pre- and post-treatment skeletal, dental, and soft tissue measurements were analysed. Statistical evaluation included paired t-tests, inter-group comparisons, Bonferroni correction, and effect size calculation.Results: Skeletal changes (SNA (angle between S, Nasion and A points), ANB (angle between A, Nasion and B points), angle of convexity, maxillary length) were significantly greater in early mixed dentition. Dental changes were more pronounced in late mixed dentition, especially upper incisor proclination (Upper 1/SN: 7.20° vs. 2.85°). Soft tissue improvements were greater in early mixed dentition, with an H-angle increase of 7.71° vs. 3.90°. Early intervention achieved greater skeletal-driven overjet correction, while late intervention relied more on dental compensation.Conclusion: Timing of palatal plate-assisted maxillary protraction significantly influences treatment outcomes. Early mixed dentition treatment provides maximal skeletal correction, minimal dental compensation, and favourable soft tissue response, supporting the advantage of early orthopaedic management in Class III malocclusion.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"40-45"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148163031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phase contrast microscope, an essential tool in the field of biology and medical research, provides improved discrimination of cellular details.Materials and methods: One-hundred twenty subjects as per selection criteria were selected by purposive sampling technique and categorised into four groups (I, II, III and IV) of 30 each: smoking tobacco users, smokeless tobacco users, both smoking and smokeless tobacco users and subjects without any deleterious habits. Fixed, unstained buccal smears were examined under a phase contrast microscope and were evaluated for cellular alterations. Normality test followed by various non-parametric tests was performed.Results: This study showed a significant increase in nuclear area, nuclear-to-cytoplasmic ratio and mean number of micronuclei per cell in combined tobacco users than tobacco chewers and smokers, but frequency of cells showing micronuclei was highest in smokers compared to tobacco chewers and combined tobacco users.Conclusions: Presence of micronuclei and cytomorphometric changes could be the earliest indicators of cellular alterations.
