BACKGROUND The purpose of this study was to investigate and compare three different pit and fissure sealants with different composition to check their effectiveness for sealing ability and microleakage. MATERIALS & METHODS Total 120 therapeutically extracted premolars devoid of any caries, anomalies or morphogenic diversity were collected and distributed equally in three groups (40 in each). ...

Mineral Trioxide Aggregate is a material developed for endodontics that appears to be a significant improvement over other materials for procedures in bone. It is the first restorative material that allows for the overgrowth of cementum and the regeneration of periodontal ligament. The present case report illustrates the use of MTA in treating a case of perforation in the furcation area with lo...

Dental treatment procedures are increasingly governed by factors such as biocompatibility of restorative materials, patients demands for esthetics and a conservative approach to minimize loss of tooth structure.G.V Black was the first person to describe the ideal cavity form to restore carious lesions. G.V Black followed “EXTENTION FOR PREVENTION” as ideal principle for cavity preparation.Such ...

64 INTERNATIONAL DENTISTRY SA VOL. 12, NO. 2 Although colour as an entity should be regarded as being only one of the many building blocks necessary in the achievement of an aesthetic restorative result, a discordant colour scheme can probably be more devastating to the overall effect than many of the other factors present. It is for this reason that so much time, research and expense has gone ...

The use of gutta-percha as a standard obturation material over more than 100 years has made little changes in the obturation technique. With the advent of bonding and composite resins as a routine restorative material, the concept of bonded obturation has come into picture. The Resilon-Epiphany system has brought about a paradigm shift in the conventional obturation technique. This article expl...

background: familial adenomatous polyposis (fap) is a well-known entity for specialistrnand it has near 100% chance of malignant changes if does not managed surgically. in orderrnto reduce the disadvantages of laparatomy and diverting ileostomy we present ourrnresults of laparoscopic total proctocolectomy without diverting ileostomy.rnobjectives: the aim of this study was to present the results...

t Muchh attention has been directed toward developing dental restorative compositess that generate less shrinkage stress during setting. The aim of this studyy was to explore the viscoelastic behavior of a new class of low-shrinkage dentall restorative composites during sett ing. The setting behavior of an experimentall oxirane composite was investigated by analyzing stress-strain data byy mean...

Cytotoxic resin components of common dental bonding agents are known to cause oxidative damage and suppress odontogenic differentiation of dental pulp cells. [1-4] As antioxidants were found to protect cells from cytotoxicity of resin monomers in previous studies,[5-8] we investigated the effects of common antioxidants, such as !-carotene, resveratrol and Vitamin E on anti-differentiation activ...

The purpose of this study was to evaluate the discoloration of two nanohybrids, two microhybrids, and a posterior composite resin restorative material upon exposure to different drinks--namely tea, cola, coffee, red wine, and water. The colors of all specimens before and after storage in the solutions were measured by a colorimeter based on CIE Lab system, and the color differences thereby calc...

Introduction: In order to determine the real efficacy and durability of polymeric dental adhesives, thorough clinical testing is necessary. However, in practice, long-term clinical testing is expensive and commercial adhesive materials are constantly undergoing change so that the clinical testing necessary to evaluate their long-term properties and success rates (typically four years) becomes i...
