Objective: The objective of this study was to compare the smear layer formed on root canal walls during canal preparation of extracted human teeth by Twisted, Mtwo, and ProTaper rotary nickel titanium instruments. Materials and Methods: Sixty single rooted human premolar teeth with root curvature <250 were selected and randomly divided into three Groups (n= 20 teeth per Group). Three types of rotary nickel titanium instruments were used, Twisted (SybronEndo, Orange, CA, USA), Mtwo (VDW, Munich, Germany) and ProTaper (Dentsply Maillefer, Ballaigues, Switzerland) according to manufacturer’s instructions to instrument the root canals. Irrigation for all groups was performed after each instrument change with 3ml of 3% sodium hypochlorite followed by Glyde (File Prep, Dentsply, Maillefer, Ballaigues, Switzerland) as chelator paste and lubricant. Three different areas (coronal, middle and apical thirds) of the root canal were evaluated using scanning electron microscopy (SEM). The canal wall of each sample was assessed and compared using a predefined scale for the presence or absence of smear layer. Data were analysed statistically using ANOVA and Tukey HSD test Results: All three groups showed statistically significant more smear layer in the apical thirds of the canal as compared to the coronal and middle thirds (p<0.001). Mtwo rotary file system produced significantly less smear layer (p<0.001) compared to Twisted and ProTaper rotary instruments in the apical portion. Twisted Files resulted in less smear layer formation in the apical thirds of the canal compared to ProTaper rotary instruments but were statistically insignificant. Conclusion: Completely clean root canals were not found after instrumentation with any of the three instruments. Under the confines of this study Mtwo instruments produced significantly cleaner dentin wall surfaces throughout the canal length in comparison to Twisted and ProTaper rotary files. Twisted Files proved to be comparable to ProTaper rotary instruments with respect to canal cleanliness in the apical thirds of the root canal. © 2015, Journal of Clinical and Diagnostic Research.

Background & objectives: Prevention of the periodontal disease progression is the primary goal of periodontal therapy. When conventional therapy is found inadequate to attain periodontal health in Chronic Periodontitis, local antimicrobial agents have been used as an adjunct with scaling and root planing which have reproduced encouraging results. This case series evaluates the newly released sustained local drug Chlosite clinically & microbiologically in smokers. Method: The patients were grouped into experimental group A treated with scaling and root planning plus Chlosite (SRP + CHL), experimental group B treated with Chlosite alone (CHL) and control group C treated only with scaling and root planing (SRP) alone. A total number of 74 sites from 3 chronic smoker patients participated in this study. The clinical parameters, Plaque index (PI), Gingival index (GI), Bleeding index (BI) and Relative attachment level (RAL), were recorded and microbiological samples taken before scaling and root planning. Results: All the groups, showed statistically significant reduction in relation to Plaque index, Bleeding index & relative attachment level. Combination of scaling and root planning with chlosite resulted in added benefits as compared to the two treatment groups. All the groups showed reduction in the microbial count of fusobacterium nucleatum, Porphromonas gingivalis and tannerella forsythesis. Interpretation and conclusion: In this study all treatment groups were found to be efficacious in the treatment of periodontal disease as demonstrated by improvement in PI, GI, BI and RAL. Combination of SRP and Chlosite resulted in added benefits compared to the two treatment groups. Source

Adenomatoid odontogenic tumour (AOT) is a benign epithelial odontogenic tumour that accounts for 3 - 7% of all odontogenic tumours and only 0.1% of tumours and cysts of jaw. In 1907, Dreibladt first described this rare tumour as pseudoadenoma adamantinum.1 Clinically it present as a slow growing, painless mass found in maxilla.More frequently seen in females and has a peak incidence in the second decade of life. There are three variants of AOT: follicular, Extrafollicular and peripheral type.2 Irrespective of the type they show similar histological appearance with gland like structures, calcifying areas and amyloid like material. A case report of adenomatoid odontogenic tumour of the maxilla, in a 20 year old male patient. Source

Aim: The aim of the present study was to assess the maternal socioeconomic status and the caries experience among 2-6 years old preschool children of Lucknow city, India. Material and Methods: A sample of 512 preschool going children were selected through a multistage cluster random sampling. Their mothers provided information regarding their demographic data. Their socioeconomic statuses were elicited by using the modified B.G.L. Prasad's classification for the year 2010. Their mothers' education, occupations and incomes were also recorded. The dental caries experience was recorded by using the dentition status and the treatment needs (WHO Basic Oral Health Survey 1997). The association between the socioeconomic status and the caries experience was obtained by using the Chi - square test. One way ANOVA was used for the multiple group comparisons. Results: The prevalence of nursing caries was 33.01%. The association between the presence of nursing caries and a lower status of the mother's education and occupation and socioeconomic position proved to be statistically significant (p<0.001). Conclusion: Instilling positive attitudes in the parents, especially in the mothers, towards the prevention of nursing caries, would reduce its prevalence at this tender age of life. Source

The odontogenic myxoma of the jaw bone is a rarely occurring, benign, slow growing, nonencapsulated neoplasm which is of ectomesenchymal origin. This neoplasm occurs almost exclusively in the jaw bones. The odontogenic myxoma may show a wide spectrum of radiographic appearances, unilocular, multilocular radiolucency and a distinct or diffuse border, making the differential diagnosis difficult. Therefore, histopathological examination is mandatory. Odontogenic myxomas have a high rate of recurrence, which ranges from 10-33% with an average of 25% and majority of recurrences occur within the first two years. Here, we are presenting two case reports of maxillary and mandibular odontogenic myxoma along with their review of literature. Source
