In vitro evaluation of surface roughness, adhesion of periodontal ligament fibroblasts, and Streptococcus gordonii following root instrumentation with Gracey curettes and subsequent polishing with diamond-coated curettes [PDF]

Clinical Oral Investigations, 2012
OBJECTIVES: The objective of the study was to evaluate the efficacy of an additional usage of a diamond-coated curette on surface roughness, adhesion of periodontal ligament (PDL) fibroblasts, and of Streptococcus gordonii in vitro. MATERIALS AND METHODS: Test specimens were prepared from extracted teeth and exposed to instrumentation with conventional

An Improved Sharpening Technique for Gracey Curettes Based on Blade Design.

Nihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 2002
スケーラーのシャープニングの目的は鋭利なカッティングエッジをつくるだけでなく, 機能的なブレード本来の形態を維持することである。本研究の目的は, グレーシー型キュレットスケーラーのブレードの形態を再評価し, その形態に基づいた新しいシャープニング方法を提案することである。Hu-Friedy社製およびNordent社製の#1, 5, 7, 11, 13それぞれ5本のグレーシー型キュレットスケーラーを実験に供した。第一シャンクを床に対して垂直に保持し, デジタル実体顕微鏡で40倍に拡大したブレードの上面像を撮影した。同様に第一シャンクを水平にしブレードの側面像を撮影した。両画像からカッティングエッジの曲率半径をコンピューターソフトを用い算出した。その結果 ...

A comparison of root surface instrumentation using manual, ultrasonic and rotary instruments: An in vitro study using scanning electron microscopy

Indian Journal of Dental Research, 2012
Background: The commonly accepted idea concerning root planing is that excessive removal of cementum is not necessary for removal of endotoxins. The ideal instrument should enable the removal of all extraneous substances from the root surfaces, without ...
