SARDINA VALDES, Maribel  e  CASAS ACOSTA, Jorge. Dental occlusion anomalies associated to temporomandibular dysfunction. Rev. Med. Electrón. [online]. 2010, vol.32, n.3, pp. 0-0. ISSN 1684-1824.

The stomatognathic system is the functional whole of the organism in charge of chewing, phonation and swallowing. It is formed by bones, muscles, teeth and joints located in both sides of the crania base and prior to the external auditive meatus. Temporomandibular joint is one of the most complex joins of the human body; it is formed by the mandibular condyle, adjusted to the glenoid fossa of the temporal bone flake, and it is considered as a ginglimoartroidal join, because it makes hinged and slipping movements. Our aim was evaluating the relation between temporomandibular dysfunction and the risk facts related with dental occlusion. We studied 119 patients who assisted the orthodontic consultation with temporomandibular dysfunction. We made them clinic oral examination using the Krogh Paulsen´s test and analyzed dental occlusion. The results showed that 111 patients had temporomandibular dysfunction (93,3 %), the most relevant risk facts were unilateral chewing, oclusal interferences and teeth lost. We arrived to the conclusion that dental occlusion alterations are risk facts leading to temporomandibular dysfunction.
