Guimarães, Geraldo Muzzi & Aguiar, Evandro Guimarães
Aim: To evaluate the prevalence of gingival recession (GR), its classification according to Miller’s
classification, and its relationship with gender, age, income and level of education, in the population
of the city of Divinópolis, MG, Brazil. Methods: Two questionnaires were distributed to the local
dentists. One of them was directed to the patients and had questions referring to gender, age and
socioeconomic conditions; the other was directed to dentists and had questions about the type of
GR found in each patient. Results: 245 patients were included in the study. GR prevalence was
higher in women. GR prevalence increased with age and seemed to stabilize after the age of 30.
There was no relationship between GR and patient’s socioeconomic status. A higher GR prevalence
was found in premolars with no statistically significant difference among them. There is a higher
prevalence of Miller’s Class I GR. Conclusions: As the prevalence of GR increases with age, a
frequency of 81.40% of GR was obtained. No correlation was found between socioeconomic level
and GR. In addition, there was no significant difference between genders on GR prevalence. A
higher Miller class I (p=0.000) prevalence was observed. There was no significant difference
between mandibular and maxillary molars. However, the mandibular premolars were the most
affected and there was a higher GR prevalence in maxillary teeth than in mandibular teeth.
