This study was conducted to evaluate the prevalence and distribution of OMLs and assess gender-related differences among children aged 0-13 years.Materials and methods: The children were clinically examined by trained professionals for the presence of OMLs using the standard diagnostic criteria. Lesions were recorded based on clinical appearance and categorised accordingly.Results: Out of the 1024 children examined, 73 were found to have OMLs, resulting in an overall prevalence of 7.12%. A slight male predominance was observed among affected children, with 54.79% ( n = 40) being boys and 45.21% ( n = 33) girls.Conclusion: The study revealed a 7.12% prevalence of OMLs among children aged 0-13 years, with a higher occurrence in boys. These findings highlight the importance of routine oral screening in paediatric populations for early identification and intervention.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147837397","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 compares the effectiveness of alloplastic versus xenograft bone substitutes in these procedures with immediate implant placement.Aim: To evaluate the effectiveness of alloplastic versus xenograft bone substitutes concerning implant stability and bone formation during sinus lift procedures with simultaneous implant placement.Settings and design: This prospective randomized study at the ITS Centre for Dental Studies and Research, Ghaziabad, from April 2022 to December 2023, involved fourteen patients randomly divided into two groups: Group 1 (alloplastic bone substitute) and Group 2 (xenograft).Materials and methods: Patients aged 30-60 with ≤5 mm residual alveolar bone height underwent sinus lift using the lateral window technique and immediate implant placement. Postoperative assessments included cone-beam computed tomography (CBCT) for bone formation and PENGUIN device for implant stability at 4 months.Statistical analysis used: Statistical analysis was conducted using SPSS 16.0 software, with significance set at P < 0.05.Results: Both groups showed significant improvements in implant stability and bone formation over 4 months. The xenograft group exhibited higher mean implant stability (71.00) and superior bone formation (11.49) compared to the alloplastic group (70.57 and 10.17, respectively). No significant differences in soft tissue reactions were noted between groups.Conclusion: Both alloplastic and xenograft materials are effective for sinus lift procedures with immediate implant placement, but xenografts show slightly better outcomes in implant stability and bone formation, warranting further long-term, multicentre studies.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147716655","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":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-15","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}

Group 1 was the control group with Tooth Wear Index 0 (TWI: 0); Group 2 had TWI grade 1-2; and Group 3 had TWI grade 3. Initially, the maximum physiologic bite force in the first molar regions were determined using Flexiforce sensors, followed by the occlusal contact area. Next, the buccal and lingual microstrain values of mandibular first molars were recorded after a physiologic bite load. Additionally, all parameters were recorded for Group 3 after composite restoration and adjustments of non-functional occlusal contacts. Data were analysed using the Kruskal-Wallis test with Bonferroni correction (P < 0.05).Results: Mean bite force values were similar between groups (P = 1.000). Mean buccal and lingual microstrain values in Group 3 were significantly higher than those of controls (P = 0.003, 0.021). Mean lingual microstrain values of Group 3 were significantly higher than those of Group 2 (P = 0.009). Restoration of molars in Group 3 resulted in reduced mean microstrain values that were similar to those of the controls (P = 0.190).Conclusion: Coronal microstrain values of mandibular molars increased with severe tooth wear but reduced after placement of composite restorations and elimination of non-functional contacts. Severe occlusal wear increases coronal strain, and placement of a bonded restoration and occlusal correction can limit further wear and fracture.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147672765","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}

Review was performed in accordance to PRISMA-DTA checklist and registered under PROSPERO (CRD42025631782). Databases were searched from January 2000 to December 2024 for studies comparing the diagnostic ability of AI models compared to dental specialists. Risk of bias (ROB) assessment was done through QUADAS (Quality assessment of diagnostic accuracy studies)-2 tool and meta-analysis was performed in Meta-Disc 1.4 software and Review Manager 5.3 for pooled sensitivity, specificity, and summary receiver operating characteristics (SROCs). Five studies were included for analysis. Included studies revealed the presence of moderate to low ROB. Various AI models analysed and evaluated as an index test were artificial neural network, convolutional neural network, direct learning, and direct learning network. Meta-analysis revealed a pooled sensitivity of 0.83 (95% confidence interval (CI) 0.31-1.00) and a pooled specificity of 0.33 (95% CI 0.03-0.81); the summary receiver operating characteristics (SROC) through area under curve (AUC) was 0.54. The included AI models were trained and evaluated on radiographic data only; therefore, findings reflect diagnostic accuracy of image-based AI in detecting radiographic signs associated with endodontic disease rather than comprehensive clinical prognoses. While AI demonstrated moderate sensitivity for identifying these endodontic conditions, low specificity indicates a high false-positive rate when used as a standalone radiograph-based tool. These models may serve as adjunctive screening aids but require prospective validation that integrates clinical and treatment variables before they can be used to predict longitudinal treatment outcomes.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"465-470"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145756503","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}

The topography, roughness, and Vickers hardness number (VHN) of polished and unpolished surfaces were evaluated. The cement film was observed with confocal microscopy. The flexural strength and maximum force at fracture of cemented molar single-unit crowns were determined.Statistical analysis: The mean values of the groups were analyzed by using the Shapiro-Wilk test and 1-way analysis of variance (α = 0.05).Results: In both techniques, no statistically significant differences were found in the VHN (P > 0.05); the roughness values of the unpolished surface increased significantly (P = 0.002). The topographic information showed that CAD-CAM milled PMMA and 3D printed resin had a smooth surface after polishing, and a cement film was observed on all the walls of the abutment surface. The flexural strength (P = 0.001) and the mean maximum failure load (P = 0.002) were significantly higher for CAD-CAM milled PMMA. The failure of CAD-CAM milled PMMA crowns was classified as minimal fracture; for the 3D printed resin crowns, the fracture was through the midline.Conclusion: Both techniques provided clinically acceptable surfaces. CAD-CAM milled PMMA exhibited significantly higher failure at maximum load than 3D printed resin.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":"36 4","pages":"444-449"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147503788","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 aims to correlate Oral Health-Related Quality of Life (OHRQoL) with dentition and periodontal status among Myanmar refugees in resettlement camps in Hyderabad, Telangana.Materials and methods: The study included Myanmar refugees aged 18 years and above who were registered under United Nations High Commissioner for Refugees (UNHCR) Refugee mandate and have refugee status card. Also, only participants who can read and understand the Burmese language and gave written consent were included. Validated Myanmar translated version of OHIP-14 was used to assess OHRQoL. Dentition and periodontal status were examined by single calibrated examiner according to WHO criteria.Results: Caries prevalence in this group of 208 participants was found to be 64.9% with a mean DMFT of 3.59 ± 3.7. Multiple logistic regression analysis reveals that a history of dental visits had significantly higher odds of poor OHRQoL (OR = 4.45; P = 0.00). Variables like age (OR = 0.30; P = 0.00), absence of gingivitis (OR = 0.11; P = 0.03) and periodontal pocket (OR = 0.32; P = 0.00) showed significantly lower odds for poor OHRQoL in this population.Conclusions: This study concluded that compromised oral health conditions among Myanmar refugees significantly affected their OHRQoL.
