Electronic buccal drug delivery system to treat addiction and chronic diseases: A porcine study in the frame of “IntelliDrug” project

examination followed by the administration of a risk factor questionnaire. A cervical, buccal, occlusal/incisal, and lingual score was recorded for each tooth using a modified version of the Tooth Wear Index (Smith and Knight, 1984). Rank correlations, one-way and two-way ANOVA were used to test for associations between risk factors and percent of surfaces with wear. Results: 44 patients (31.9%) had at least one cervical lesion 1-2mm deep. 118 patients (85%) had dentin exposure on at least one incisal edge. Cervical lesions were most frequently observed on mandibular 1 premolars. Incisal/occlusal wear was most common on mandibular central incisors. Age was significantly correlated with over…
