CUNHA, Fábia Ferreira de Albuquerque da et al. Oral lesions diagnosed in a public oral pathology laboratory. RGO, Rev. gaúch. odontol. (Online) []. 2013, 61, 4, pp. 595-601. ISSN 1981-8637.

Objective The aim of this study was to perform a retrospective study of 1,894 maxillofacial injuries diagnosed in a public laboratory in Mato Grosso and verify the association by considering the following variables: gender, age, anatomical locationand origin of the patient (capital, interior). Methods A sample was selected in the period from2005 to 2008 in order to assess the prevalence of oral lesions in a Public Laboratory (MT Laboratório). Results Chronic gingivitis was the most prevalent lesion, with a frequency of 11.46%, followed by inflammatory fibrous hyperplasia (7.44%), mucocele (7.23%) and fibroma (5.54%). Females were affected in50.63% of cases and males49.37%. However, there is no difference in gender (p=0.435). The second decade of lifeshowed a higher prevalence of injuries. The region of the jaw proved to be the most affected (24.45%) and most patients came from the interior. There was a statistically significant association between some pathologies and sex(p<0.001) among the most prevalent anatomical locations and gender (p<0.001) and origin of the patient (p<0.001). Conclusion It can be concluded that chronic gingivitis was the most prevalent lesion. There was a statistically significant association between some pathologies and sex, amongst the most prevalent anatomical locations and sex and origin of the patient.
