Interaction between toothpaste abrasivity and toothbrush filament stiffness on the development of erosive/abrasive lesions in vitro.
OBJECTIVES To investigate the loss of enamel and dentin surface caused by the interaction between abrasives in toothpaste and toothbrush filament stiffness. METHODS The study followed a 2 (high-level or low-level abrasive; silica) × 3 (filament stiffness; soft, medium or hard) × 2 (cycling time; 3 or 5 days) factorial design. Polished bovine enamel and dentin specimens (n = 8 each per group) ...

The objective of this study was to estimate the level and frequency of non carious cervical lesion with in patient’s dentition reporting with this condition and to investigate factors that might played frequent role in its etiology. Targeting these factors and severity levels, an accurate treatment modalities can be designed. This descriptive cross sectional study was conducted at Outpatient De...
متن کاملNo carious cervical lesions: abfraction.
Abfraction or Theory of Abfraction is a theory explaining the non-carious cervical lesions (NCCL). It suggests that they are caused by flexural forces, usually from cyclic loading; the enamel, especially at the cementoenamel junction (CEJ), undergoes this pattern of destruction by separating the enamel rods. Clinical aspect importance of these ineart lesions are at most important to be detected...
