Combined use of povidone iodine (PI) along with topical fluorides (TF) has been suggested as a promising strategy to reduce dental caries incidence and cariogenic bacterial load. However, the available literature presents mixed evidence regarding its effectiveness as compared to TF application alone. 'TF + PI' vs TF alone in the prevention of dental caries among 1-12-year-old children assessed through caries increment and mean and counts. Five databases (Cochrane Central Register of Controlled Trials, EBSCOhost, PubMed/Medline, Scopus, and Web of Science) were searched for relevant literature. Out of 72 studies that were screened, 7 eligible studies were included out of which 4 studies were subjected to meta-analysis. The generic inverse variance test was used to assess the primary outcome reported as mean ± SD/events occurred (caries incidence), whereas for mean post-intervention colony count, inverse variance function was used. https://www.selleckchem.com/products/tucidinostat-chidamide.html The Cochrane's Collaboration tool and Modified Downs and Black scn added benefit with TF in preventing the occurrence of new carious lesions among 1-12-year-old children.

This systematic review has been conducted in line with the preferred reporting items for systematic reviews (which is also called as PRISMA) guidelines. A search for the relevant articles of zirconia crowns in deciduous teeth has been made in electronic database of PubMed and a study design (meta-analysis), i.e., PICOS framework. The words used in the search are "zirconia crowns" and "primary molars," "zirconia crowns" and "primary incisors," "zirconia crowns" and "children," "zirconia crowns" and "primary teeth." The database search showed 44 studies of which 20 articles were excluded as they were irrelevant, duplicates, and data were not available. In the present systematic review, the remaining 24 articles were included. Zirconia crowns have been proved with better results than other crowns in terms of gingival and periodontal health, esthetics, and crown fractures. However, the quantity of tooth preparation and the wear of antagonist tooth are reported to be more in case of zirconia crowns. Future randomized control studies should be carried out in primary teeth due to less number of randomized studies on this topic. Zirconia crowns are now widely used in dentistry and there is an increase in the number of studies, so a systematic review evaluating and comparing results is warranted.

Among the various plants studied, cinnamon has emerged as a potential herbal antimicrobial agent. Besides the medicinal plants, recently probiotics have also been recognized to affect cinnamon bark oil and other harmful oral and gut microflora. This placebo-controlled study aims to compare the antimicrobial potential of cinnamon bark oil incorporated and probiotic blend [ (TSP-Lp1), and (TSP-Lrh1)] incorporated mucoadhesive patch against salivary in caries active 7-10-year-old children. It was a double-blinded placebo-controlled study with = 60. They were randomly allotted into three groups-Group I Cinnamon patch, group II probiotic patch, and group III control patch (placebo) with = 20 in each group. The study was carried out in three phases. In the first phase, the minimal inhibitory concentration (MIC) of cinnamon bark oil was determined against followed by the formulation of cinnamon and probiotic patches. After a washout period of 2 weeks and a collection of baseline saliva sa, Srilatha KT, Deshmukh S, Comparison of Antimicrobial Efficacy of Cinnamon Bark Oil Incorporated and Probiotic Blend Incorporated Mucoadhesive Patch against Salivary in Caries Active 7-10-year-old Children An Study.

The critical aspect is to reproduce fine surface details along with ease of use. Knowledge of impression materials and the techniques to which each is best suited is essential in achieving consistent results. The purpose of this study is to evaluate the accuracy of various putty-wash techniques in a laboratory model that simulated the clinical practice. A metal master model, containing three full crowns fixed partial denture (FPD) abutment preparations, was fabricated. A perforated custom tray was fabricated that can be placed in the same position on the master model for each impression. For each technique, 10 impressions of the master model were made and poured using a die stone. The measurements were made of the models using a measuroscope and the accuracy of the impressions was recorded. The statistical comparison between groups I, II, III, and IV casts measurements by using the Mann-Whitney test showed highly significant statistical difference between the various groups from each other ( < 0.001). The accuracy of the working casts obtained from group III impression (two-step using 1 mm coping) was the best, whereas it was least with group II impression (two-step using polyethylene spacer).
