Sometimes, they are made to assess the outcome of a specific therapy for definitive prosthesis. Hence, understanding the properties, manipulation methods, and uses of provisional restorative materials for fixed partial denture is essential for all dentists. The objective of the study was to assess the recent advancement in provisional restorative materials for dental prosthesis available now. Literature search on PubMed and Google Scholar was done from January 1965 to March 2022 using the keywords such as provisional and interim restorative materials. In addition, hand search was done through refereed dental journals for 2000 to 2022. Nanoparticle-reinforced provisional restorative materials for any fixed dental prosthesis had better mechanical properties compared to conventional provisional materials available in the market. Digitally fabricated provisional materials eliminate the impression and the laboratory fabrication procedures, so that it consumes less time for fabrication.","PeriodicalId":31361,"journal":{"name":"Journal of Oral Research and Review","volume":"15 1","pages":"65 - 71"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48171083","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}

Local and systemic factors are implicated in its occurrence. Objectives: The aim of this study was to estimate the prevalence of PSs in a sample of the North Indian population using dental panoramic radiographs, and to report its association with age, gender, tooth class, dental arch, and restorative status of the teeth (restored/unrestored). Materials and Methods: A total of 500 panoramic radiographs were randomly sampled from the archived dental records of patients treated in the dental hospital from 2015 to 2021. 450 panoramic radiographs containing 10,007 teeth met the inclusion criterion and were evaluated for the presence of PSs. The frequency of occurrence of PS between age, gender, tooth class, dental arch, and restorative status of the teeth was also calculated. Results: PSs were detected in 128 (28.44%) out of the 450 patients, and 369 (3.68%) of the 10,007 teeth examined. A χ2 test of independence did not reveal any statistically significant association of PS with gender, age, and dental arch. The presence of PS was greatest in molars, and the results were statistically significant compared to all the other tooth types. The frequencies of PS were higher in the first molars (18.21%) than in the second molars (9.01%) when consolidated data for both arches were analyzed (P < 0.05). Carious/restored teeth displayed a statistically significant higher prevalence of PS than unrestored and intact teeth (12.95% vs. 10.32% prevalence rate as a ratio of total teeth examined). Conclusions: The etiology of PSs is not completely validated. Further studies are needed to establish the factors involved in PS formation and evaluate its association with systemic diseases.","PeriodicalId":31361,"journal":{"name":"Journal of Oral Research and Review","volume":"15 1","pages":"28 - 33"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48027059","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}

Methodology: Two SB systems were evaluated: SB-1 group (Polyetheretherketone (PEEK)/Flag shaped, Biohorizon, USA), and SB-2 group (Titanium/cylindrical shape, Bioline, GmbH). On completely edentulous mandibular model with 4 dental implants (TMR 4.6, Biohorizon, USA) with scan bodies were positioned in the first molar and canine. The model was scanned using a calibrated laboratory scanner (D2000; 3Shape) to generate a master reference model (MRM). Ten consecutive digital impressions Standard Tessellation Language file were made of the model using an intraoral scanner (Trios, 3Shape A/S) for both the test groups. The test scans were superimposed over the MRM using a best-fit algorithm, and then, the distance deviation and angular deviation of the scan bodies were calculated. Scan time was also recorded. Mann–Whitney U-test was used to statistical analysis. P > 0.05 considered statistically significant. Results: Statistically significant differences were found between the SB material and shape on the linear measurement, angular deviation, and scan time (P < 0.05). The SB-1 group achieved higher accuracy overall and also exhibited noticeably lower scan time. Conclusion: The quality of digital intraoral impressions seems to be influenced by both the geometry and material of the SB. For clinical practice, the PEEK material seems clinically beneficial for decision-making.","PeriodicalId":31361,"journal":{"name":"Journal of Oral Research and Review","volume":"14 1","pages":"114 - 120"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45482488","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}

Its antimicrobial and anti-inflammatory properties, led to its increasing medical applications. Commercially available as wound dressings, surgical instruments and bone prostheses. Objectives: To compare physical parameters of nano-copper and silk suture. Methodology: Copper nanoparticles and deionized water were adopted for the preparation of the copper solution. The copper solution was obtained by dissolving 0.5 wt/v % of copper nanoparticles in a mixture of 5 v/v % of deionized water. The silk suture were dipped in the copper solution for 24 hr and then exposed to UV lamp in order to induce the synthesis of copper clusters on the surface of the suture. Inverted electron microscopy was performed in order to analyse the braided structure of the multifilament silk sutures and to verify the presence of copper on the surface. A quantitative spectrophotometry analysis was performed to quantify the percentage of copper deposited. Tensile strength was measured by Universal Testing Machine. Results: Nano-copper suture showed enhanced physical parameters as compared to silk suture. Conclusion: Copper nanoparticles due to their beneficial effects as antibacterial and wound healing accelerator in the periodontal surgeries could reduce inflammation and promote healing process.","PeriodicalId":31361,"journal":{"name":"Journal of Oral Research and Review","volume":"14 1","pages":"104 - 108"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42166225","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}
