Aim: The purpose of this investigation is to evaluate the physicochemical properties of saliva, such as salivary flow rate, volume, pH and buffer capacity and the levels of salivary sodium, potassium, calcium and phosphate ions in caries-free and caries-active children. Materials and methods: The present study included 100 healthy children aged 7-12 years belonging to a rural population from Thiruvallur district (in Chennai, India), who were divided into Group I caries-free and Group I caries-active children, of 50 children each. Unstimulated saliva was collected by draining method and flow rate and volume were determined. The samples were then analysed for pH and buffering capacity using a manual pH meter. Sodium, potassium, and calcium concentration were analysed by Flame Photometer. Phosphates were analysed by Fiske and Subbarow's colorimetric method. Data were then statistically analysed using the Student's t-test (unpaired). Results: The results revealed that when all these parameters were compared among the caries-free and caries-active children, the flow rate, volume, pH and buffering capacity were slightly reduced in the caries-active group and this was statistically significant, whereas the calcium, potassium and sodium concentrations were increased in the caries-free group in a statistically significant manner. Conclusion: Within the limitation of this study, we can conclude that alterations in the physicochemical properties of saliva such as increased salivary flow rate, volume, calcium, sodium and potassium concentrations play a major role in the development of resistance to caries.

Background: Sodium hypochlorite solutions have been evaluated for their effects in bonding procedures as they are found to deplete or remove the organic portion of the dentin, particularly the collagen fibrils. The aim of this in vitro study was to assess and compare the efficacies of 1%, 2.5%, 5% and 10% NaOCl at 30, 60 and 120s on etched primary dentin. Methods: 84 primary anterior teeth were ground to expose a flat dentin area on the buccal surface. The specimens were divided into fourteen groups of six each based on the dentin surface treatment (35% phosphoric acid etching for 7 seconds-AE and/or NaOCl application), NaOCl solution concentrations (1%, 2.5%, 5% and 10%) and time of application (0, 30, 60 and 120s). Specimens were prepared for SEM and photomicrographs were taken of the surface and were scored against a five point scale, based on the smear layer and amount of collagen removed. The scores were submitted to Kruskal-Wallis and Mann Whitney tests. Results: This study showed the presence of smear layer in the control group. The group treated with Acid Etchant showed a demineralized pattern of dentin with exposure of dentin tubules and collagen fibrils network on the intertubular and peritubular dentin which was not significantly different from the groups treated with 1% and 2.5% NaOCl. Groups treated with 5% NaOCl were not statistically different from each other, the surface was corroded but collagen fibrils were not completely depleted. Groups treated with 10% NaOCl were not statistically different from each other and showed complete removal of collagen fibrils with wider tubular apertures and several secondary tubules on peritubular and intertubular dentin. Conclusion: Higher concentrations of NaOCl solutions (5% and 10%) produced significant changes in the etched primary dentin. The higher the concentration of the NaOCl solution, the lower can be the time for the application of the solution for the complete removal of collagen fibrils. Source

Odontogenic tumors (OTs) include entities of a hamartomatous nature, such as odontoma, benign neoplasms like an adenomatoid odontogenic tumor (AOT), some benign neoplasms are aggressive as in the case of ameloblastoma. The AOT is a rare odontogenic tumor constituting only 3% of all the OT and very often misdiagnosed as an odontogenic cyst. We report a case of an intra-osseous type of AOT occurred in a young 16-year-old female located in the anterior maxilla along with the clinical, radiological, histological features, and literature review related to the tumor affecting the patient. © 2015 Journal of Pharmacy And Bioallied Sciences | Published by Wolters Kluwer - Medknow.

Over the past two decades, there has been an explosion of interest in Autism Disorder (AD). Knowledge and awareness on the condition has grown exponentially at all levels among the general public, parents, health professionals, the research community and more recently, at parliamentary level. The world has begun to recognize the scope of this problem and act internationally and locally to improve the lives of the growing number of individuals and families affected by this devastating disorder. This article reviews the dental literature since 1969 and it summarizes characteristics of patients with AD, oral health status and dental management of patients with AD. Source

Background: The aim of the study was to examine the in vitro antibacterial activity of different oils in comparison to antiseptics against oral microorganisms. Methods: The antimicrobial effect of tea tree oil (TTO), eucalyptus oil (EO), lemon grass oil (LGO), and a eucalyptus-based oil mixture (MXT) were tested in comparison to Chlorhexidine digluconate (CHX), povidone-iodine (BTA), and octenidine dihydrochloride (OCT). Oral bacterial strains and Candida species using the agar diffusion test were used for the antimicrobial study. Results: All tested oils showed antimicrobial potency against the tested biological indicators. In comparison of all tested substances the largest effective zones were measured for LGO, followed from MXT and CHX. TTO and EO were less effective against the tested micro-organisms followed from BTA. Conclusions: The results of this study show that some essential oils have better antimicrobial properties than standard oral antiseptics. In a follow-up step, the ideal concentrations, the composition of essential oils, and the mode of application will be evaluated. The antibacterial efficacy of essential oils might be promising for use in clinical and oral hygiene applications. The cost reduction and availability particularly in rural areas with easy access to the originating plants might be advantageous factors to be considered. Source
