Comparison of Different Methods of Enamel Preparation Before Pit and Fissure Sealants

2015-11-02 16:23:22 | BioPortfolio


This study concerns the prevention of dental caries by sealing pits and fissures of permanent molars with a photopolymerizable resin. It must compare these three techniques Microdentisty (air abrasion, abrasion and sound using small cutters) usually used to prepare micro cavities in the enamel and / or the outer third of the dentin. These three commonly used techniques have never been compared by retaining as endpoint retention of sealant. These techniques are painless and do not require local anesthesia.

Bioactive Materials Subjected to Erosion/Abrasion and Their Influence on Dental Tissues.

The objective of this study was to evaluate the effect of erosion or erosion-abrasion on bioactive materials and adjacent enamel/dentin areas.

Electromyographic characteristics of chewing muscles of individuals with pathological abrasion of hard dental tissues.

Introduction: Pathological abrasion of hard dental tissues is accompanied by both morphological and functional disorders of the dentofacial system. Among the functional changes, changes in the bioelec...

The impact of polyethylene abrasion on the occurrence of periprosthetic proximal femoral fractures in patients with total hip arthroplasty.

In addition to abrasion-induced osteolysis and ensuing instabilities, the polyethylene (PE) abrasion of total hip arthroplasty (THA) inlays can also cause gait instability due to the decentralization ...

Medical and Biotech [MESH] Definitions

A technique using a pneumatic, high-pressure stream of aluminum oxide to remove DENTAL ENAMEL; DENTIN; and restorative materials from teeth. In contrast to using DENTAL HIGH-SPEED EQUIPMENT, this method usually requires no dental anesthesia (ANESTHESIA, DENTAL) and reduces risks of tooth chipping and microfracturing. It is used primarily for routine DENTAL CAVITY PREPARATION.

The property of dental enamel to permit passage of light, heat, gases, liquids, metabolites, mineral ions and other substances. It does not include the penetration of the dental enamel by microorganisms.

An acquired or hereditary condition due to deficiency in the formation of tooth enamel (AMELOGENESIS). It is usually characterized by defective, thin, or malformed DENTAL ENAMEL. Risk factors for enamel hypoplasia include gene mutations, nutritional deficiencies, diseases, and environmental factors.

Epithelial cells surrounding the dental papilla and differentiated into three layers: the inner enamel epithelium, consisting of ameloblasts which eventually form the enamel, and the enamel pulp and external enamel epithelium, both of which atrophy and disappear before and upon eruption of the tooth, respectively.

The susceptibility of the DENTAL ENAMEL to dissolution.
