Background and Aim:The present study was undertaken to evaluate the pH, buffering capacity, viscosity and flow rate of saliva in caries free, minimal caries and nursing caries children and to evaluate the relationship of these on the caries activity of children.Materials and Methods:A total of 75 school children of age group between 4 and 12 years were selected and divided into three equal groups: Group I, Group II and Group III, consisting of 25 subjects each. Group I included caries-free subjects, Group II included subjects with minimal caries and Group III included subjects with nursing caries. Saliva samples were collected from all subjects and were estimated for flow rate, pH, buffering capacity and viscosity.Results:There was a significant decrease in the mean salivary flow rate, salivary ph and salivary buffer capacity and a significant increase in the salivary viscosity among caries-free subjects, subjects with minimal caries and subjects with nursing caries.Conclusion:The physicochemical properties of saliva, such as salivary flow rate, pH, buffering capacity and viscosity, has a relation with caries activity in children and act as markers of caries activity.

AIM:The purpose of the study is to achieve the baseline information of the autistic child’s oral health status about the diet, dietary and hygiene habits. The association of these factors with dental caries were assessed.MATERIAL AND METHODS:The survey was composed of self-administered questionnaires to parents about their children’s’ demographic data followed by questions related to diet, dietary and hygiene habits. This is later followed by oral examination for estimating the decayed, missing and filled [dmft] scores as per WHO norms. The variables are analysed using t-tests and ANOVA. Pearson’s correlation coefficients were calculated for each of the independent variables to examine for autocorrelation.RESULTS:The mean age for the present study is 5.8 years with more predilections of caries in females. The autistic children prefer soft diet and pouch it in oral cavity resulting in increased caries though not significant. Other foods like nuts and pulses confectioneries and soft drinks resulted in increased caries, and our study shows significant relation. Consumption of sugars between meals and increased quantity of sugar per day also increased dental caries with highly significant results in our study. Hygiene habits also made a difference in the occurrence of caries though, in our study, it’s not significant.CONCLUSIONS:The study suggests that the oral health education programs should be conducted for the parents, caregivers and the teachers about the diet, dietary and the hygiene habits and the role they play in maintaining the oral hygiene.

The current study was aimed to fabricate customized root form dental implant using additive manufacturing technique for the replacement of missing teeth. The root form dental implant was designed using Geomagic™ and Magics™, the designed implant was directly manufactured by layering technique using ARCAM A2™ electron beam melting system by employing medical grade Ti-6Al-4V alloy powder. Furthermore, the fabricated implant was characterized in terms of certain clinically important parameters such as surface microstructure, surface topography, chemical purity and internal porosity. Results confirmed that, fabrication of customized dental implants using additive rapid manufacturing technology offers an attractive method to produce extremely pure form of customized titanium dental implants, the rough and porous surface texture obtained is expected to provide better initial implant stabilization and superior osseointegration.

Aims and Objectives:Self-rated oral health is the key element that has a greater effect on quality of life and found to be authentic and logical to consider this as an indicator for overall oral health status. The aim was to investigate and identify the impact of various social and clinical factors on the perceived self-rated oral health status (PSR-OHS).Materials and Methods:A self-administered questionnaire was distributed 600 patients seeking information for age, gender, nationality, educational level, and their last dental visit followed by 15 questions related to social factors (patient self-rated oral health, patient-dentist communication, literacy level of the patient, and dental neglect) followed by estimating the clinical oral health status (decayed, missing, and filled teeth [DMFT] scores as per WHO norms).Results:The results were estimated by a single five-point-response-scale question dichotomized into poor and good self-rated oral health. The average mean age for participation in the study is 32.5 years and found to be highly significant (P < 0.01) with inverse relation indicating that younger patients give better PSR-OHS. There were no significant differences in PSR-OHS among other demographic factors. Patients visiting the dentist recently found to be confident about their PSR-OHS and are statistically significant. Pearson correlating scores of social factors and the DMFT scores most concerned in the present study have a significant relation with self-rated oral health status.Conclusions:PSR-OHS is governed by various dental health and awareness factors. It can be used as an important tool by a clinician to assess the clinical examination results which helps to achieve more effective time and patient management.

Chemical disinfection and autoclave sterilization had no statistically-significant effect on the tested properties of elastomers, thus autoclave sterilization can be considered as an alternative and an effective mode of disinfection and sterilization to eliminate all forms of disease causing microorganisms from dental impressions.
