For medical reasons, teeth 38 and 48 were removed from each patient, as well as a fragment of the alveolar part of the lower jaw in the projection of teeth 38 and 48 measuring 0.5 × 0.5 cm. The odontological parameters, the mineral density of the enamel and the lower jaw, the length and width of the enamel prisms, the spatial organisation of collagen fibrils and the dimensions of the bone plates of the lower jaw were determined.Results: A decrease in optical density was observed at the age of 41-50 and 51-60 years with dysplasia, which indicated a decrease in mineral density and the presence of total areas of hypomineralisation relative to the age of 31-40 years. In the age groups of 41-50 and 51-60 years, pronounced sclerosis and deformation of the delimiting elements were observed at the border of the connective tissue structures and the periosteum. At the age of 31-40 years, the level of stratification of the bone plates was local; after 40 years, it was generalised.Conclusions: Progressive osteoporosis of the lower jaw and incomplete amelogenesis are obstacles to the correct and harmonious eruption of the lower 'wisdom' teeth after 30 years.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142286051","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 association of leptin concentration (GCF) was measured before and after orthodontic force was applied to move the mesially impacted canine distally (tooth movement distance on dental cast).Statistical analysis: With the help of SPSS software version 21, the data were statistically examined using the \" t \" test, one-way ANOVA, and Bonferroni correction in Chicago.

Clinical parameters in both groups were recorded at baseline (t0) and six months (t1) postoperatively in terms of gingival recession height (RH), root coverage esthetic score (RCES), visual analogue scale (VAS), and healing index (HI).Results: The RH, RCES, VAS, and HI were significantly reduced at the end of six months compared to baseline ( P < 0.005) in both groups; however, there was no statistical difference between the groups, indicating the equivalent efficacy of AFG and conventional sutures in healing.Conclusion: All the treated sites were found to have appreciable root coverage with satisfactory post-operative healing.

Each group was further subdivided into two sub-groups depending on the test used: fracture resistance test and push-out bond strength test. The all specimens were mounted in acrylic resin blocks and tested using a universal testing machine. The fracture and failure mode were determined by a stereomicroscope inspection of all the specimens.

Osseointegration is critical for the success of dental implants. Implant surface modification can enhance osseointegration. Gold nanoparticles have emerged as a promising coating material for dental implants owing to their unique physicochemical properties. We aimed to review published literature to assess the effect of gold nanoparticle coating in increasing osseointegration of dental implants.Data collection: A database search yielded a total of 14 articles between January 2011 till December 2021, of which nine articles were excluded and five studies met the inclusion criteria. All studies reported improved osseointegration outcomes with gold nanoparticle coating compared to uncoated controls.Results: The most reported osseointegration outcomes were bone-implant contact, removal torque (RTQ) and histological analysis of bone formation around the implant. Mean RTQ values for coated implants ranged from 6.7 to 52.8 Ncm, compared to 3.7-40.8 Ncm for uncoated controls. The histological analysis showed greater bone formation and density around the coated implants compared to uncoated implants. Gold nanoparticle coating appears to have a positive effect on osseointegration. The results of included studies suggest that gold nanoparticle-coated implants promote greater bone-implant contact (BIC), RTQ and bone formation around the coated implant than the uncoated implant.Conclusion: With increasing usage of dental implants, the most prevailing concern among clinicians remains to be peri-implantitis. Peri-implantitis is observed despite the biocompatibility and osseointegration properties of titanium. Surface coatings with antimicrobial effectiveness can help in preventing the onset of peri-implantitis and bone loss, while increasing BIC.","PeriodicalId":13311,"journal":{"name":"Indian Journal of Dental Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142286050","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 patients were assigned to two groups ( n = 70). In group 1, Transbond XT resin cement, and in group 2, G-CEM had been used for bracket bonding. The frequency and severity of WSLs in each group were evaluated by assessing the available post-treatment photographs of patients and notes left by their orthodontist in their records in this regard. The number of teeth with WSLs in each patient was recorded, and the severity of lesions was categorised by Gorelick's analysis.Statistical analysis: Comparisons were made using independent t -test, Wilcoxon test and Mann-Whitney test (alpha = 0.05).Results: In both the maxilla and mandible, the prevalence of WSLs was significantly higher in the Transbond XT group than in the G-CEM group ( P = 0.01). The difference in frequency of WSLs between the maxilla and mandible was not significant within each group ( P > 0.05).
