TÍTULO: Objective Assesment of Simulated Non-Carious Cervical Lesions by Tridimensional Digital Scanning
PALAVRAS-CHAVES: Non-carious cervical lesions, Toothbrush, Toothpaste, Dentifrice, Abrasivity, Dental technology.
PÁGINAS: 44
RESUMO: To explore the use of 3D intraoral scanner/image analysis for the detection and monitoring of simulated non-carious cervical lesions (NCCLs) in vitro. MATERIALS AND METHODS: A total of 288 NCCLs of different severities and simulated using a laboratorial model associating toothbrush stiffness (soft, medium and hard) and toothpaste abrasivity (low, medium, high and negative control) were analyzed. Dental impressions were taken from specimens before and after 35K and 65K brushing strokes, and then scanned with a CEREC Omnicam scanner. 3D models were analyzed for volumetric tooth loss. 3D optical profilometry was considered as gold-standard. Data were analyzed using ANOVA and Fisher’s PLSD tests (alpha=0.05), and agreement between methods by using intraclass correlation coefficient. RESULTS:Toothbrushes of hard and mid stiffness caused higher tooth loss than soft when associated with the highest abrasive, at 35K and 65K strokes (p<0.001). Variation in slurry abrasivity led to differences in tooth loss (with control
