Introduction: Though the negative influence of tobacco consumption on the periodontal status of an individual is established, the magnitude of this association based on the type of tobacco used is seldom investigated. Aim: The aim of this study is to check the differences in the periodontal status of individuals based on their current tobacco consumption status and type of tobacco consumption. Materials and Methods: This study was conducted among subjects attending a teaching dental institution in Andhra Pradesh. Subjects were divided into three groups based on their current tobacco consumption status. The following parameters were recorded after examination by two calibrated investigators: number of sites with bleeding on probing; number of teeth with periodontal pockets; number of teeth with clinical attachment loss of ≥5 mm; number of teeth lost. SPSS version 20 software was used to analyze the data. Results: While current users demonstrated poor periodontal status than the former and nonusers, there was a significant difference in periodontal health between former users and nonusers in all the study parameters except the mean number of teeth lost. Among current users, the mean percentage of sites with bleeding and attachment loss >5 mm were found to be least among smokers compared to tobacco chewers and those who consume both smoke and smokeless forms of tobacco. Conclusion: The study confirms the negative influence of tobacco consumption on periodontal health and also establishes the increased destruction of clinical attachment levels among tobacco chewers compared to smokers.

Introduction: Recently, Dental Council of India directed all the teaching dental institutions in the country to set up tobacco cessation centers (TCC). International experiences suggest that there are many barriers for the provision of tobacco cessation counseling at dental clinics. In this context, it is important to understand the dental students’ attitudes toward this initiative of tobacco cessation counseling at dental settings. Materials and Methods: This qualitative study to document the dental students’ perspectives toward the provision of tobacco cessation counseling using focus group interviews was conducted in two teaching dental institutions in the state of Andhra Pradesh, India. 133 house surgeons from two dental institutions participated in the study and were interviewed as 13 focus groups. MAXQDA (version 12, VERBI GmbH, Berlin, Germany) was used for data analysis. All the interviews were audio recorded and the transcripts were open coded by three independent investigators. Results: The response rate in this study was 78.45%. The following themes were extracted from the views and opinions shared by the students: the reluctance of patients to discuss tobacco-related problems; tobacco use among students discouraging them to actively participate in counseling; an opinion that dental clinics are not suitable for the provision of tobacco cessation counseling; belief among students that they are not qualified enough. Conclusion: The directives given by the Ministry of Health and Family Welfare in association with Dental council of India to set up TCC at every teaching dental institution are laudable and demonstrate the commitment at policy level toward bringing down tobacco consumption in the country. However, few reforms need to be made in the curriculum to better execute the delegated responsibilities, which include orientation programs for dental students on the scope of the dental profession and workshops on tobacco cessation counseling.

Background: In endodontics, the three processes of biomechanical preparation, disinfection, and obturation are each essential. The electron microprobe and scanning electron microscope (SEM) allowed for the detection and identification of the smear layer and debris. The purpose of the current investigation was to use a scanning electron microscope to evaluate the relative merits of two single-file systems, the reciprocating WaveOne and the continuous motion F360 files, in the cleaning and contouring of root canals in removed teeth.Materials and method: The 50 central maxillary permanent teeth Data was gathered from the Oral and Maxillofacial Surgery Division at Sri Ganganagar's Maharaja Ganga Singh Dental College and Research Centre for a number of reasons. Group A followed the manufacturer's guidelines for using the WaveOne instrument, whereas Group B utilised the F360. Reciprocating motion WaveOne system (group A) and continuous motion F360 system (group B) root canals were scored at three levels: coronal third, middle third, and apical third (group B). SPSS version 22 was used for the data analysis. The data were examined using the chi-square test and the one-way analysis of variance.Results: A greater quantity of smear layer was found in the apical third, whereas better results were achieved in the coronal and middle thirds. When compared to the F360 file system, the WaveOne file system is subpar when it comes to clearing the canal of debris. While both groups showed a large amount of debris in the apical third, outcomes were somewhat better in the coronal and middle thirds. Conclusion:The WaveOne and F360 file systems were both more effective in removing trash from the coronal and middle thirds of the disc than they were from the apical thirds. In comparison to the continuous motion F360 file system, WaveOne files demonstrated a statistically significant reduction in the amount of debris cleared from root canals in all three root zone thirds (coronal, middle, and apical). The reciprocating action of the WaveOne file system, in contrast to the continuous motion of the F360 file system, resulted in more extensive cleaning of the root canal smear layer in the coronal and middle thirds and less thorough cleaning in the apical thirds of the canal.

Aim: The goal of this study was to see how accelerated artificial ageing (AAA) affected the colour of composite resins used in dentistry. Materials and Methods: We piloted an invitro study with 2 nanofilled Premise and Filtek Z350 and microfilled Spectrum TPH. A total of 90 specimens equally distributed for the three composites were selected. The color measurements were obtained with a Spectrophotometer before and after invitro aging. Data were analyzed using chi square test with p <0.05. Results: There was observed a significant variation in the shades of all the composites.  There was a significant variation between the Nanocomposites and the microfilled composites. Conclusions: All composite resins depicted a color change and the size of the particles may have impacted the staining of the composites in vitro. Key words: Color, Composite Resins, Aging.
