Abstract

Due to the aversive taste of medications, there is said to be a struggle in making the child consume it. The ease of administration of liquid suspensions makes it accepted by parents & children for oral administration. Because of the aversive taste of medications, cariogenic sugars such as sucrose is said to be added as a flavoring agent to mask the unpleasant taste. This sucrose in the medication is said to cause dental caries. The dental professionals have the opportunity to provide advice regarding the importance of diet & the role of sugars in caries formation. The dentist should be familiarized with alternatives to sugar & the type of food products that are available to substitute with sweetening agents.

Keywords

Cariogenic Bacteria, Sweetening Agents, Sucrose, Risk Factors.

Abstract

Aim: To determine the effect of Eugenol based temporary cements on bond strength of RMGIC and RelyX ARC.

Materials and Method: A total of fortymolars were sectioned 3mm below the occlusal surface and roughened surface was smoothened by 60-grit sand paper. Zinc oxide eugenol was given as a temporary restoration for 20 molars and the rest were not exposed to eugenol. Zinc oxide eugenol was removed using ultrasonic scaler and viewed under magnification for precise removal. 20 molars not exposed to eugenol were divided into group 1 (RMGIC) and group 3 (Resin). Other 20 teeth which were exposed to Eugenol were also divided similary into group 2 (Eugenol+RMGIC) and group 4 (Eugenol+Resin). Shear bond strength (SBS) testing was done using knife edge blade in the universal testing machine (INSTRON) at CIPET in Chennai.

Results: On comparing Shear Bond Strength using t-test, no statistical significance (p>0.05) was found between RMGIC groups whereas between Resin groups statistical significance was found.

Conclusion: When ZOE was used as temporary cement there was a decrease in shear bond strength for resin cement but no difference was observed in RMGIC groups.

Abstract

Flare-up can be defined as the occurrence of swelling, pain or the combination of these during the course of ischolar_main canal therapy, which results in unscheduled visits by patients. Inter appointment pain is caused mainly by microbial injury to the periradicular tissues and to some extent by iatrogenic factors which are chemical and mechanical in nature. The offending agents cause inflammation in the periradicular tissues which result in pain and swelling. While post endodontic flare-up is a relatively rare occurrence, the sudden increase in patient symptoms demands for a focused and active treatment plan. This review article discusses these many facets of the flare-up: definition, aetiology, clinical symptoms and management of the situation after its occurrence.

Abstract

The word Ceramic originated from the Greek term keramos meaning “potter or pottery”.

Dental ceramics have long been recognized for their similarity to dental enamel. They can be made to closely mimic the shades and textures of the natural tooth. Porcelain provides the practitioner with the clinical ability to restore a patient›s dentition to its original appearance and function. The biocompatibility and user-friendliness of dental ceramics are unmatched in any other restorative material. Demands for more esthetic and metal free restorations as well as soaring metal prices are causes for the increase in all ceramic prosthesis. (10) Over the past two decades, the use of bonded porcelain has expanded exponentially owing to the increasing demand for esthetic restorations and prosthesis. This article is an attempt to summarise the many facets of dental ceramics.

Abstract

Waste is a direct consequence of human activity and the quantity of generated waste is often an indicator of the economic strength and development of a community. Dentistry is a profession which is dedicated to promoting and enhancing oral health and well being. Dentists use a variety of materials and equipment to accomplish this goal. Unfortunately, some of these materials present potential challenges to the environment. This article is an effort to discuss the various materials the hazards caused by them and their appropriate disposal technique.

Keywords

Abstract

A successful ischolar_main canal treatment is based on diagnosis, treatment planning, knowledge of tooth anatomy, and concepts of debridement, sterilization, and obturation. Several techniques of obturation are available for ischolar_main canal treatment. The choice depends on the anatomy of the canal and unique objectives of treatment in each case. The two common obturation procedures are lateral compaction and warm vertical condensation.

Abstract

Root canal failures occur at a rate of 10-15 % (Wong 2004). When teeth cannot be treated appropriately by ischolar_main canal treatment or retreatment, endodontic surgery is usually the last option considered for saving the tooth. These procedures consist of periapical curettage, ischolar_main-end resection, ischolar_main-end preparation and ischolar_main-end filling material being placed at the resected apex so as to act as a seal between the periodontium and ischolar_main canal system. Harty et al. in 1970 reported that the apical seal was the single most important factor in achieving success in such surgery. So to achieve a perfect hermetic seal an ideal ischolar_main-end material is required. A ischolar_main-end material also requires other properties such as biocompatibility, easy handling, stability etc. This article is an overview on the newer ischolar_main-end or retrograde materials that have been used so far in practice.

Abstract

The dental operating microscope and the ultrasonics have found many important applications in dentistry. Ultrasonics is undoubtedly imperative for improving the quality of the treatment and for handling difficult cases in endodontics. It is useful in procedures such as gaining access to canal openings, cleaning and shaping, obturation of ischolar_main canals, retrieval of separated instruments, removal of intracanal medicaments and blockages and endodontic surgery.This review throws some insight on the applications of ultrasonics in endodontics today.

Abstract

Aim: The aim of this study is to compare and evaluate the cyclic fatigue resistance of 3 different Nickel Titanium rotary file systems: Hyflex CM, Neoendo Flex files and ProTaper Gold by static method in three different curvatures, namely, 45°, 60° and 90°.

Materials and Method: Thirty Hyflex CM (25/.06), Thirty Neoendo Flex (25/.06) and Thirty Protaper Gold (25/.08) instruments were included in this study. The static cyclic fatigue test was performed using a custom-made jig. The artificial canal is made of stainless steel jig with an inner diameter of 1.5mm, a 45°, 60°, 90° angles of curvature and radii of curvature of 5 mm. All the instruments were rotated according to manufacturer’s recommendations until failure occurred. The time taken to failure was recorded in seconds for each group using a digital chronometer. The data were analyzed statistically using one way ANOVA, Post hoc test of Bonferroni was performed to identify pair-wise significance via SPSS 21.0 software (SPSS Inc, Chicago, IL). The statistical significance was set at 5%.

Result: In 45° and 60° Hyflex CM and Neoendo Flex are better than Pro Taper Gold. At 90°, Neoendo Flex is better than Hyflex CM (P<.05).

Conclusion: Within the limitation of this study, it can be concluded that, Neoendo Flex files exhibited highest cyclic fatigue resistance at 90° angle of curvature. In 45° and 60° angle of curvature Neoendo Flex files and Hyflex CM rotary instrument were more resistant to cyclic fatigue. Protaper Gold showed the least cyclic fatigue resistance than the other files tested.
