Influence of kinetic cavity preparation devices on dental topography: an in vitro study.
AIM The objectives of this study were to assess the influence of four different kinetic cavity preparation devices on cavity preparation taking into account tip angulation, internal tip diameter, and distance to the dental substrate. The dental topography itself was also evaluated after the use of these devices. METHODS AND MATERIALS Quantitative parameters using pertinent statistical tests a...
متن کاملEffectiveness of Er:YAG laser in cavity preparation for retrograde filling--in vitro study.
The purpose of this study was to determine the sealing quality of Super EBA cement in laser prepared root-end cavities in comparison with root-end cavities classically prepared with steel burrs. Two groups of three millimeter root sections were prepared. The first group was prepared with the Er:YAG laser and the second group with a steel burr mounted on a surgical handpiece. The sections were f...
متن کاملIn vivo study of respiratory depression of pulp tissue resulting from cavity preparation and dental materials.
Pulpal respiration in second and third premolar dog teeth was measured by a radioisotope tracer determination. Dental amalgam, a zinc oxide and eugenol base, and a calcium hydroxide base were placed into a cavity preparation. Following a two-week period the teeth wer~ extracted intact. The pulp tissue was removed and suspended in a phosphate buffer saline solution (PBS) which 14C-succinic acid ...
متن کاملEvaluation of two different root-end cavity preparation techniques: A scanning electron microscope study
OBJECTIVE In this study, we aimed to evaluate and compare the dentinal walls of root-end cavities for the presence of cracks after cavity preparation using US retrotips and Er: YAG laser. MATERIALS AND METHODS Fifty single-rooted teeth were prepared by Protaper NiTi rotary system and obturated by lateral condensation. Three milimeters of root-end was resected. Twenty teeth were prepared with ...
