FERNANDEZ-CORREA, Lillien et al. Key I of occlusion according to the Andrews criteria and temporomandibular disorders. Rev. inf. cient. [online]. 2021, vol.100, n.2 Epub 01-Mar-2021. ISSN 1028-9933.
Introduction:
The study of occlusion and its role in the etiology of temporomandibular disorders has been a controversial topic of interest in the stomatological field.
Objective:
To determine the relationship between occlusion, according to key I of the Andrews criteria, and temporomandibular disorders.
Method:
An observational, descriptive, cross-sectional study was carried out on students of dentistry at the Clínica Estomatológica Docente Provincial of the city of Sancti-Spíritus, in the period from September 2018 to September 2019. The population was of 42 students, the simple random sample consisted of 40 of them, those who responded to the inclusion criteria. The study variables were: presence of temporomandibular disorder, canines and molars ratio and coincidence of dental midlines. Methods of the theoretical, empirical, statistical and mathematical levels were used.
Results:
52.5% of the patients presented temporomandibular disorders, of which the molar relationship was bilateral in 80%. Regarding the relationship of canines, all those affected presented a relationship of mesio, disto or a combination of them. Most of the unaffected (89.5%) had midline coincidence.
Conclusions:
It is found that any alteration in dental occlusion according to the Andrews criteria will have consequences on the stomatognathic system and, therefore, on the appearance of temporomandibular disorders.
