Bruxism. Effects for the stomatognathic apparat (Original)

Abstract

An investigation was carried out with the objective of determining the possible association between bruxism and its clinical effects on the stomatognathic apparatus. To achieve the intended objective, a cross-sectional analytical observational study was carried out. From a population of 563 patients between 30 and 50 years old from office number 31 in the Pedro Pompa neighborhood, a sample of 294 patients was studied by intentional non-probabilistic sampling. The variables studied were: bruxism, oral effects and facial effects. The percentages and the statistical association between the variables were used as summary measures and the Odds Ratio was determined. The representative effects were: headache in the temporal region (80,08%), Temporomandibular Joint disorder (76,49%), pain in the cervicofacial muscles (74,50%), wear facets (99,20%), dental fractures (98,01%), exposed dentin (75,30%), bone exostoses (73,71) and cervical abfractions with (58,96%). Finally, the association of bruxism with facial and oral effects was demonstrated: facets of wear (OR=190,412), dental fractures (OR=215.250), dentinal hyperesthesia (OR=34,921) with no association showing the effects: mandibular dislocation, vertigo, exposure pulp, tooth fractures, tooth loss, periodontopathies and traumatic injuries. In this research, the association of bruxism with facial and oral effects for the stomatognathic apparatus was determined, such as headache in the temporal region, temporomandibular joint disorder, pain in the cervicofacial muscles, hypertrophy of the facial muscles, wear facets, target fractures, dentinal hyperesthesia, exposed dentin, bone exostoses and cervical abfractions.
