[Assessment of tooth wear depending on Smith and Knight index]. / Evaluarea leziunilor dentare necariogene în functie de indicii Smith si Knight.

UNLABELLED: For the clinical diagnosis of tooth wear Smith and Knight have been suggested the index with the same name, the criteria for the quantification of the hard tissue loss being the size of the area affected and the depth of the defect. The aim of this study was to assess tooth wear depending on Smith and Knight index, on a group of 614 patients. MATERIAL AND METHOD: The criteria for the selection of the patients were the age more than 18 years old and the Smith and Knight index >0. RESULTS: The biggest proportion of tooth wear (47.3%) presented the value 2 of the Smith and Knight index. Most of the tooth wear with Smith and Knight index 3 (54.4%) are abrasions, 71.4% of the tooth wear with Smith and Knight index 1 are attritions, and 20.3% of the tooth wear with Smith and Knight index 3 are erosions. High alcohol consumption is associated with deep tooth wear, exposing dentine (value 2 and 3 of the Smith and Knight index). Currently, various indices are used, making the comparison of the results of prevalence studies difficult.

[Clinical study on the distribution of tooth wear of the adult population]. / Studiu clinic asupra distributiei leziunilor dentare necariogene la populatia adulta.

UNLABELLED: Tooth wear is becoming increasingly significant in the developed societies, because the etiological factors are frequently present in the daily life. The aim of this study was to assess the distribution of the tooth wear of the adult population in a private practice of dentistry. MATERIAL AND METHOD: The group of study had 614 patients, structured on the following subgroups of age: 18- 30 years, 31-40, 41-50, 51-65 and more than 65 years old. Each patient had a clinical exam and a questionnaire for the diet and the lifestyle, spotlighting the etiology of tooth wear. RESULTS: attrition was the most frequent (55.7%), followed by abrasion (32.7%), erosion affected 7.5% of the patients and abfractions are the least frequent (4.1%). Erosions (9.7%) and attritions (59.9%) are more frequent at the feminine gender, and abrasions (40.4%) at the masculine gender. More than half of the abfractions (56%) were found at the youth patients (18-30 years old). Erosions were found in the 31-40 years subgroup at almost 40% of the patients; in the 41-50 years subgroup, abrasion and erosion were found in equal proportions. Abrasion prevails at the 51-65 years subgroup (30.8%). 72% of the consumers of acidic fruits had dental erosions. CONCLUSION: Tooth wear is under the influence of the diet and the age factor.
