The data collection process involved obtaining real-time digital recordings of occlusal contacts and pressures within the natural dentition.Results: One-way ANOVA was performed as it was found that there is a significant difference in the values on both sides. Tukey's post hoc test for multiple pairwise comparison was performed, and it was found that there is no significant difference between the first and second premolars. There is also no significant difference between the first and second molars on both sides.Conclusion: The first molar exhibited maximum bite force distribution.

Diabetic individuals are more susceptible due to impaired immunity, delayed healing, and reduced infection clearance. While systemic bacteremia is well-studied, localized bacteremia from the alveolar socket remains underexplored. This study compares post-extraction bacteremia in diabetic and non-diabetic patients to improve infection risk assessment and preventive care.Objectives: 1. Compare alveolar socket bacteremia in diabetic and non-diabetic patients. 2. Assess bacteremia prevalence and severity in both groups. 3. Evaluate the impact of diabetes on post-extraction bacteremia. 4. Identify predominant bacterial species and their clinical relevance. 5. Examine associations between bacteremia, glycemic control, healing response, and infection risk.Materials and methods: Sixty patients (30 diabetics, 30 non-diabetics) aged 30-70 from low-to-medium socioeconomic backgrounds were studied. Males predominated among diabetics, females among non-diabetics. Post-extraction socket blood was collected, cultured on blood agar, and incubated at 37°C for 24 hours. Bacterial identification was performed using microscopic examination and confirmatory assays.Results: Statistical analysis ( p ≤ 0.05) showed diabetics had higher Streptococcus (56.6%), Enterococcus (26.6%), Klebsiella (3.3%), and Candida (3.3%), while non-diabetics had Enterococcus (40%), Streptococcus (30%), Moraxella (16.6%), and Escherichia coli (3.3%). Staphylococcus and Pneumococcus were exclusive to diabetics.Conclusion: Localized bacteremia may indicate systemic health risks. Further research is needed to establish clinical correlations, refine treatment protocols, and improve early intervention strategies.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"154-160"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144784228","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 systematic review and meta-analysis evaluated the prevalence of C-shaped canal anatomy in mandibular second premolars and examined the influence of geographic variation on prevalence rates.Materials and methods: The study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, systematically searching five electronic databases: PubMed, Web of Science, ScienceDirect, Scopus, and Google Scholar. Eligible studies included cross-sectional, prospective, and observational studies on C-shaped canal prevalence in adult mandibular second premolars.Statistical analysis: A random-effects model in RStudio software was used to calculate the pooled prevalence and 95% confidence intervals (CI) of C-shaped canals.Results: The pooled prevalence based on participants was 1.31% (CI: 0.68-2.53; I² = 90%; P < 0.01). Based on the number of teeth, the prevalence was 0.96% (CI: 0.46-2.00; I² = 93%; P < 0.01), also with high heterogeneity. Geographic analysis showed the highest prevalence in South America 5.83% (CI: 0.57-40.04; I² = 95%; P < 0.01) and the lowest in Australia 0.42% (CI: 0.31-0.93).Conclusions: The study demonstrated variability in the prevalence of C-shaped canals, with a pooled estimate of 1.31% based on participant-level data and 0.96% based on tooth-level assessment. The substantial heterogeneity observed across studies highlights the morphological diversity of root canal systems. Geographic differences were observed, with the highest prevalence in South America and the lowest in Australia. These findings underscore the importance of region-specific diagnostic vigilance.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":"36 2","pages":"228-235"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145212328","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}

A vibration device was constructed using 3D printing technology and employed a vertical vibration system. Three vibration cycles were utilized, including frequencies of 30 Hz, 60 Hz, and 90 Hz. Each cycle had durations of 1, 5, and 10 min/h, with a total duration of 6 h. The control group underwent no vibrational loading. After 24 h, analysis was conducted using an inverted microscope and a spectrophotometer. Alkaline phosphatase (ALP) expression was assessed using an ALP Kit.Results: The study yielded highly significant results ( P < 0.001). cell activity was found to be highest with 30 Hz vibration loading compared to both 60 Hz and 90 Hz ( P < 0.001). Among the various durations tested, the 30 Hz vibration with a 5-min cycle per hour, totalling 6 h, exhibited the highest cell activity. Additionally, ALP expression was most pronounced with 30 Hz vibrational loading. The cells displayed a dark green appearance surrounded by a pale green extracellular matrix.Conclusion: The highest cell activity and ALP expression were reported with the 30 Hz vibrational loading lasting 5 min/h, over a total duration of 6 h. However, a decline in cell activity was observed with both increased duration and frequency.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":" ","pages":"197-201"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505566","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}

Whitening efficacy was evaluated by spectrophotometer, and the enamel surface alteration was examined by scanning electron microscope.

The paired t-test was used to assess the differences in colour variation between the middle third and the cervical third, independently for each of the groups.Results: The analysis of colour variation (ΔE) showed that there was no statistical difference among the groups with or without application of a desensitizer (P > 0.05). The change in enamel morphology was proportional to the concentration of the bleaching agent.

Densities of CD64 + M1 and CD163 + M2 macrophages were assessed in the epithelial and sub-epithelial areas.Results: A significant correlation between macrophage sub-populations in OLP was observed ( P < 0.001). Within OLP, higher densities of CD64 + M1 and CD163 + M2 macrophages were detected in sub-epithelial areas.

Groups 1, 2 and 3 comprised individuals with average, horizontal and vertical facial skeletal patterns, respectively. The Planmeca Romexis viewer software was used to assess variables in the multi-planar reformation view of CBCT in the sagittal plane.Statistical analysis: Descriptive statistics were calculated as mean and standard deviation. Comparison between the groups was performed using analysis of variance, followed by Tukey's post-hoc test. An independent sample t -test was carried out to compare between genders. The level of significance was 5% ( P < 0.05).Results: Significant differences were found in condylar angulation, AEh and AEI in individuals with different skeletal patterns.
