Aims: To observe prevailing injuries in the oral mucous membrane in patients with nervous bulimia and/or nervous anorexia and to determine if there is a relationship between the injuries in the oral mucous membrane and eating disorders.Materlals and Methods: 65 patients with eating disorders were examined. 46 patients had nervous bulimia and 19 had nervous anorexia. All patients were female and their ages ranged from 12 to 32 years. The control group was made up of 65 female people aged 14 to 31 years without diagnosed eating disorders.Results: In the group of patients with eating disorders 61 patients had injuries in the oral rnucous rnembrane (94 porcentage) with 112 injuries in all; whereas in the control group only 12 patients (1 8.5 porcentage) had a total of 15 injuries in the oral mucous membrane. The most frequent injuries in the control group were exfoliative cheilitis (28 cases, 43.07 porcentage), lip erythema (28 cases, 43.07 porcentage), yellow palate (23 cases, 35.38 porcentage), purpuras (17 cases, 26.15 porcentage), cheek biting (12 cases, 18.26 porcentage) and unspecific palate atrophy (5 cases, 7.69 porcentage). In the control group the injuries occurred with the following frequency; exfoliative cheilitis (7 cases, 1 0. 77 porcentage), lip erythema (0 case, 0 porcentage), yellow palate (1 case, 1. 54 porcentage), purpuras (3 cases,4.62 porcentage), cheek biting (4 cases, 6.15 porcentage), and unspecific plate atrophy (0 case, 0 porcentage). According to the statistical analysis (Fisher Test) there are important statistical differences for each of the injuries in the observed group and in the control group (p<0.05).Conclusions: Tthe injuries in the oral mucous membrane in patients with nervous bulimia and /ornervous anorexia show a relationship with eating disorders and are useful for an early diagnosed guidance.

Objetivos: Observar la prevalencia de lesiones de la mucosa oral en pacientes con bulimia y/o anorexia nerviosa, y determinar si existe asociación entre las lesiones de la mucosa oral y los trastornos alimentarios. Materiales y Métodos: se examinaron clínicamente 65 pacientes con trastornos alimentarios (46 con bulimia nerviosa y 19 con anorexia nerviosa) todos de sexo femenino, de entre 14 a 31 años de edad, sin trastornos alimentarios diagnosticados. Resultados: en el grupo de pacientes con trastornos alimentarios, 61 individuos presentaron lesiones en mucosa oral (94%), con un total de 112 lesiones; mientras que en el grupo control lo hicieron solo 12 pacientes (18.5%), presentando un total de 15 lesiones en la mucosa oral. Las lesiones más frecuentes en el grupo con trastornos alimentarios fueron queilitis descamativa (28 casos, 43.07%), eritema labial (28 casos, 43.07%), paladar amarillo (23 casos, 35.38%), púrpuras (17 casos, 26.15%), mucosa mordisqueada (12 casos, 18.46%) y atrofia inespecífica del paladar (5 casos, 7.69%). En el grupo de control estas lesiones se presentaron con una frecuencia de queilitis descamativa (7 casos, 10.77%), eritema labial (0 casos, 0%), paladar amarillo (1 caso, 1.54%), púrpuras (3 casos, 4.62%), mucosa mordisqueada (4 casos, 6.15%) y atrofia inespecífica del paladar (0 casos, 0%). El análisis estadístico (Test de Fisher) indicó que existen diferencias estadísticamente significativas para cada una de las lesiones entre los grupos de estudio y control (p<0.05). Conclusiones: las lesiones de la mucosa oral en pacientes con bulimia y/o anorexia nerviosa presentan una asociación con dichos trastornos alimentarios y sirven para una orientación diagnóstica temprana.
