RESUMO
Objetivos: El objetivo de éste estudio és observar la posible influencia de las fuerzas oclusales según el grado de atrición de las piezas dentarias sobre la altura de la cresta alveolar. Material y métodos: Se estudiaron dientes de cráneos secos de la época actual y secomparó el desgaste oclusal ó atrición (A) con la pérdida de altura de la cresta alveolar (CA) ó recesión ósea (RO) y ambos registros se relacionaron estadísticamente. Resultados: De todos los dientes estudiados 2 tuvieron grado de atrición (GA) 0, 170 grado 1, 96 grado 2 y 15 grado 3. Registrando la recesión ósea (RO) las medidas extremas promedio estuvieron entre 2,80mm y 5,30mm; la mayor RO promedio se encontró en la parte media de las caras libres (pieza 23) y la menor en distal (pieza 11). Conclusión: No hay correlación entre la recesión ósea y el desgaste oclusal ó atrición.
Aim: The aim of these work is to know the relaciònship between the bonerecessiòn and the attritiòn.Materials and methods: We taken 228 teeth belonging to 25 dry skullsof actual edge and we compare the bone recession (BR) with the occlusalwaer or attrition (A) and both to be related with a statistical analyses.Results: Of all the teeth studied, 2 had attrition degree 0, 170 degree 1,96 degree 2 y 15 degree 3. Regarding the BR the measures differ between2,80 to 5,30mm. The BR major average was in the middle of the free aspect(tooth 23) and the minor in distal (tooth 11).Conclusion: There are not correlation between bone recession andocclusal wear or attrition.

PURPOSE: The objective of this study was to determine the severity, distribution, and correlates of tooth wear in a sample of Mexican-American and European-American adults drawn from a community-based longitudinal aging study on oral health. MATERIALS AND METHODS: The maxillary teeth of 71 subjects enrolled in a longitudinal aging study were assessed using a previously introduced five-point (0 to 4) ordinal scoring system in which each tooth is given a score describing the severity of wear. The tooth wear scores were compared with data concerning demographic factors, functional/parafunctional habits, soft drink consumption, and bite force measurements to determine specific correlates of tooth wear. RESULTS: The mean wear score for all teeth was 1.50 on the five-point scale. There was a significant difference between the mean wear score of anterior teeth (1.85) and posterior teeth (1.17). Bivariate analyses detected a moderate degree of correlation between maxillary tooth wear and age and bite force. Maxillary tooth wear was significantly greater in males and in subjects with reported teeth clenching/grinding. Multivariate analyses revealed that age, gender, bite force, self-reported teeth clenching/grinding, and number of daily meals/snacks had significant correlations with maxillary tooth wear. CONCLUSION: The overall severity of maxillary tooth wear in this sample of Mexican-American and European-American adults was low, with anterior teeth having a greater degree of wear than posterior teeth. Age, gender, bite force, teeth clenching/grinding, and number of daily meals/snacks are potential factors that may have contributed to tooth wear in the study sample.
