Abstract
Patients undergoing periodontal prosthodontics may require preperiodontal temporization. The acrylic resin temporary restorations will be required to endure through the periodontal phase of treatment as well as the prosthodontic phase of treatment. Dental plaque has been acclaimed by many as a prime etiologic factor in periodontal disease.
An investigation of dental plaque accumulation on temporary acrylic resin bridges was performed to observe if dental plaque accumulated more readily on the acrylic resin than on natural tooth structure. The literature contains little about the temporization phase of treatment and dental plaque accumulation on acrylic resin temporary restoration.
Cold cure acrylic resin temporary bridges were constructed with accepted contour and relined in the mouth with cold cure acrylic resin to assure adequate fit to abutment teeth. The patients were instructed to continue with good oral hygiene procedures during the entire investigation.
Adjacent gingival areas of a natural tooth, a polished temporary, and an unpolished temporary were compared for dental plaque accumulation utilizing an in vivo replica technique. The Silflo positive, made from a hydrocolloid impression, was viewed under a scanning electron microscope to investigate surface texture and plaque accumulation immediately after cementation, after twenty four hours, after one week, and after two weeks.
The study revealed that properly prepared temporaries compare favorably with natural tooth structures for accumulation of dental plaque. Natural tooth surfaces and polished and unpolished acrylic resin surfaces accumulated microscopic dental plaque approximately to the same degree over the two week investigation. There appeared to be a faster initial dental plaque accumulation on the unpolished acrylic resin due to the increase of surface area per square area.
Scanning electron micrographs revealed high ridges and deep furrows present in the unpolished acrylic resin which protected the bacteria from oral hygiene procedures.
