Surface Roughness of a Dental Restorative Material and Biofilm Formation

2014-07-23 21:47:00 | BioPortfolio

Summary

In this study we intend to find out the pattern of biofilm accumulation in vivo on various surface finishings.

Our intention is to prepare Polymethylmetacrylate squers on orthodontical brackets,then prepare the surface of the sample and measure the surface roughness with a profilimeter and get the mean value in Ra units, then place the brackets on lower premolars and molars for 12 hours, remove them and examine the biofilm formed with confocal scanning microscope.

Description

Several studies in the past to assess the effects of surface roughness on the amount of plaque accumulation in vitro, whereas only few performed a modern in vitro assessment of the plaque accumulation. In this study we intend to find out the pattern of biofilm accumulation in vivo on various surface finishings.

Our intention is to prepare Polymethylmetacrylate squers on orthodontical brackets,then prepare the surface of the sample and measure the surface roughness with a profilimeter and get the mean value in Ra units, then place the brackets on lower premolars and molars for 12 hours, remove them and examine the biofilm formed with confocal scanning microscope.

Statistical evaluation of pilot study determined the need to perform this research on twelve(12) candidates. It is our intention to check two materials in each candidate: composite resin and polymethylmetacrylate.

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.

A relatively hard, translucent, restorative material used primarily in anterior teeth. (From Boucher's Clinical Dental Terminology, 4th ed, p50)

The degree of approximation or fit of filling material or dental prosthetic to the tooth surface. A close marginal adaptation and seal at the interface is important for successful dental restorations.

Preparation of TOOTH surfaces, and of materials bonded to teeth or DENTAL IMPLANTS, with agents and methods which roughen the surface to facilitate adhesion. Agents include phosphoric or other acids (ACID ETCHING, DENTAL) and methods include LASERS.

Preparation of TOOTH surfaces and DENTAL MATERIALS with etching agents, usually phosphoric acid, to roughen the surface to increase adhesion or osteointegration.
