Concrescence in Primary Dentition: A Case Report
Get PDFConcrescence is the connection of two or more teeth by root cementum alone after the tooth crown has been formed. The incidence of concrescent teeth is reported to be highest in the posterior maxilla. The presence of concrescent teeth may influence teeth extraction as well as periodontal, endodontic, orthodontic and even prosthodontic diagnosis and treatment planning. Unexpected complications arising from this condition may lead to legal complications. Therefore, consideration should be given to the possible occurrence, recognition, and implications of this anomaly in diagnosis and treatment planning. The purpose of this article is to report a case of teeth concrescence between upper primary incisors with grade II mobility as it was near exfoliation

Modern Tools in Forensic Dentistry
No full textForensic Odontology is a relatively new science that utilizes the dentist’s knowledge to serve the judicial system. It has established itself as an important and often indispensable science in medicolegal matters and in particular in identification of the dead. Worldwide, dentists qualified in forensic science are giving expert opinion in cases related to human identification, bitemark analysis, craniofacial trauma and malpractice. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognize malpractice, negligence, fraud or abuse, and identify unknown humans. This article presents a literature review referring to the understanding the various methods employed in forensic odontology.  
Effect of 10% carbamide peroxide bleaching gel on marginal Integrity of tooth colored restorative materials : An invitro microleakage study
No full textAims and objectives: To evaluate the effect of 10% carbamide peroxide bleaching gel on marginal integrity of tooth colored restorative materials. Materials and Methods: Forty five human premolar teeth extracted for orthodontic reason with good enamel integrity were selected for the study and divided into three groups of 15 teeth each. Class-V cavities were prepared on the buccal surfaces of the teeth. The cavities were restored with composite resin, resin modified glassionomer, and conventional glass ionomer in the respective groups. 10 teeth in each group were subjected to thermocycling. After thermocycling the teeth were exposed to the bleaching agent. The remaining teeth were kept aside as control. After bleaching, all the teeth, including the control groups were subjected to microleakage analysis. Results: Statistical significant differences(P<0.001) were seen between the control groups and the experimental groups. The marginal integrity of the resin modified glass ionomer was less affected while exposing to bleaching, when compared to composite resin and conventional glass ionomer. Conclusion: The results suggest that resin modified glass ionomer performed better at both enamel and dentin margins when compared to the other two experimental groups.  
Comparison of anticariogenic effect of Amalgomer CR, Fuji VII and Heliomolar Refill in the cavosurface margin- An in-vitro study
No full textSecondary caries is one of the primary causes for the dental restorations failure. The frequency and severity of this problem can be reduced by using fluoride containing restorative materials. With the preludence of biomimetic esthetic restorative material along with their reinforced physical properties and caries resistant activity, this investigation assessed their capacity to resist caries in the cavosurface margin invitro. Cavity with a dimension of 2mm´3mm´1.5mm was prepared in buccal / lingual surface of 40 extracted sound human premolars. The teeth were randomly divided into four groups of 10 each and were restored with experimental materials namely Amalgomer CR (Advanced Health Care Ltd.), Fuji VII (GC Corporation), Heliomolar Refill (Ivoclar Vivadent) and Fusion Alloy (Heraeus Kulzer Int.). After 12 weeks in caries activating solution (pH 4.3) for caries-like lesion formation, the teeth were sectioned occluso-gingivally through the middle of the restoration and examined under transmission light microscope. The statistical analysis [Kruskul-Wallis Test (H) and Mann-Whitney ‘U’ test (Z)] showed the anticariogenic efficacy of Amalgomer CR was very highly significant followed by Fuji VII, Heliomolar Refill and the least by Fusion Alloy
Comparison of Root Canal Cleaning Ability of ProTaper and Liberator Rotary NiTi Instrument Systems-A SEM Study
No full text Effective cleaning and shaping of the root canal system is essential for achieving the biological and mechanical objectives of root canal treatment. The objective of this study was to compare the root canal cleaning effectiveness of two different rotary Nickel-Titanium instruments using scanning electron microscopy. In Group 1-cleaning and shaping was done using ProTaper to size 30 (F3) and in Group 2- cleaning and shaping was done using Liberator to size 30 (6%). Two uninstrumented teeth in each group were taken as control group. Instrumentation was done according to manufacturer’s instructions. The intracanal irrigant used after each file was 2 ml of 3.0% sodium hypochlorite. All samples were decoronated, split buccolingually for evaluation under SEM to determine canal cleanliness. All teeth were analyzed with the SEM at 20.0 kV and 500 magnifications in the middle third of the canal. Result showed the amount of debris present after root canal instrumentation with Liberator and ProTaper were statistically insignificant
