The purpose of  this survey was to determine the prevalency of lesions in the oral membrane in a population of pregnant women who attend the Dentistry Service of Maternidad Concepción Palacios. Information was obtained of  251 patients during the period January - July 2.003.Diagnoses of lesions in the oral mucosal were made on the basis of the clinical history and characteristics, according to the WHO,1.978. The results show the presence of one or more lesions in 100% of the sample.Gingivitis was the most frequent oral lesion in pregnant women:251 cases (100%),followed by subprosthetic stomatitis and aphthous ulcers 16 cases (6.37%),and third,gingival swellings with 14 cases each (5.57%).The greatest prevalence of oral lesions was in the group of 20-29 years, with 99 cases (39.4%).The highest amount of oral lesions found according to the pregnancy time were located in the second quarter of the pregnancy period. 57,7 % (145 cases). 15.1%(38 cases) of patients had smoking habits; it was reported 1 case (0.40%) of use of drugs and no patients were found with alcohol habits. In conclusion,we can say,on the basis of our research ,that gingivitis is the most frequent oral alteration associated to pregnancy due to an increase in the levels of hormones in the blood plasma,in addition to the presence of local irritating agents.
