DIAZ FERNANDEZ, José Manuel; PEREZ ARREDONDO, Ricardo; RODRIGUEZ PEREZ, María de los A.  e  RUIZ PEREZ, Maribel. Valoración de la presencia y estado de erupción del tercer molar inferior en las fracturas del ángulo mandibular. Rev Cubana Estomatol [online]. 1998, vol.35, n.3, pp. 102-106. ISSN 1561-297X.

A prospective study was performed in 176 patients presenting mandibular factures, treated in Maxillofacial Surgery Service of «Saturnino Lora» Teaching Provincial Hospital, Santiago de Cuba (1990-1995), to analyse possible interrelation between angle fractures and presence and state of eruption of inferior third molars. We check out that incidence of such fractures was significant when non-erupted inferior third molars were present, a remarkable predisposition against angle fracture when this one was bilateral, as well as that non-erupted inferior third molars weakened mandibular angle, both qualitatively as quantitatively; that is, a direct relationship between amount of bone space, occupied by non erupted inferior third molar and weakness of bone area was proved.
