Health care has changed dramatically by the union of computers and telecommunications. Implications for physicians and hospitals have already gained an extensive media attention, although relatively lesser information gained in terms of the impact of information technology on dentistry. Teledentistry is the use of telecommunications and information technology for dental care, education, consultation and public awareness. The present article reviews the basis, origin, scope, rationale and requirements for teledentistry, along with the illustration with the help of current evidence that exists in the literature of how the digital transformation will likely affect the dentists and their patients.

Introduction: Ceramic brackets exhibit generally high bond strength and enamel surface damage after debonding. Aim of the study: To evaluate and compare shear bond strength and enamel surface changes while de-bonding different ceramic bracket systems Materials and methods: Three types of ceramic brackets (polycrystalline Clarity; 3M Unitek, Monrovia, Calif; monocrystalline Inspire Ice; Ormco, Orange, Calif and Radiance; American orthodontics, USA) were bonded to extracted maxillary premolars, with Transbond XT light cure adhesive paste (3M Unitek). The sample consisted of 90 extracted maxillary premolar teeth. 15 bonded teeth of each type, were tested on UTM and 15 bonded teeth, were removed by pliers according to the manufacturers recommendations. After debonding with pliers ARI scores and SEM analysis of tooth surface and bracket base were evaluated under different magnifications (30X and 500X). Results: The mean SBS value of Inspire Ice, Radiance and clarity Advanced were 22.81± 2.02 MPa, 17.93±1.63 MPa and 17.28 ±1.45 Mpa respectively. ARI score showed that most of the adhesive left on the tooth surface of monocrystalline brackets. SEM analysis showed that enamel surface changes in the form of open focal holes on tooth surface and globules were found on the corresponding bracket base. Conclusion: The highest SBS with minimum enamel surface damage observed on Inspire Ice.

Page no 99-105
Introduction: Human nutrition refers to the provision of essential nutrients necessary to support human life and health. Poor eating habits and lack of nutritional knowledge are crucial public health issues that have serious health implications, through proper dietary education for their patient's, dentists play a significant role in preventing nutritional-related diseases. Aim and Objective: The current study set to evaluate the knowledge, attitude, and practice (KAP) on diet counseling among dental practitioners. Materials and Methods: A cross-sectional study using a pre-tested structured questionnaire written in English, which includes 25 questions based on knowledge of the dental practitioners about diet and nutrition counseling, which were given to 200 participants and the participants asked to respond to each item. Data analysis was performed using SPSS software 21.0 and presented as descriptive statistics and Logistic Regression (p < 0.05%). Results: Of the subjects, 78% agreed that nutrition was a vital component of total health care. However, only 46.8% of the participants reported that they had received adequate training in diet counseling. Most of the subjects agreed that diet counseling needed to be emphasized in dental education, 28.9%, and only 40% of the participants expressed their confidence in rendering diet counseling to their patients. Conclusion: The present study concluded that most of the participating subjects had basic knowledge regarding diet and its importance in oral health. Lack of confidence, time, and apprehension about financial reimbursement were three main reasons cited as obstacles for the incorporation of diet counseling in routine clinical practice.

The prime concept behind root canal treatment is to achieve a proper coronal and apical seal. Apicoectomy (root-end resection) with retrograde filling is a widely followed procedure to encounter the condition when all the efforts of endodontic treatment have failed. Among various ideal requirements of a root-end filling material, proper sealing ability is one of the most required properties. So, the selection of appropriate root-end filling material is to be done to prevent microleakage in the apical area after root-end resection. This study aims to evaluate the apical microleakage of two root-end filling materials. "Biodentine," which is known for its excellent biocompatibility and "MTA Repair HP," which has superior handling properties are compared in this study. Root canal treatment till obturation is done for all the samples. Root-end resection is done by removal of the apical 3mm with an angulation of 90° to the long axis of the tooth. The root end cavity of a depth 3mm is made. The samples were randomly divided into two groups, group 1 - MTA Repair HP, group 2 - Biodentine. Materials were manipulated according to the manufacturer’s instructions, and the root end cavities were filled with the respective materials of the belonging groups. Two coats of nail varnish is applied, and the samples were immersed in methylene blue dye. Dye penetration study was done, and specimens wereexamined under a stereomicroscope. Results are tabulated and statistically analyzed. Within the limitations of the study, it is concluded that, in comparison to these two root-ends filling materials, Biodentine showed the highest sealing ability and less microleakage compared to MTA Repair HP, which showed moderate microleakage.
