Relationship between the types of upper labial braces and the presence of gingival recessions in adult patients of the rehabilitative dental center, lima in the period January – March 2021

Abstract

The relationship between the types of upper labial frenulum and the presence of gingival recessions in adult patients at the Rehabilitoral Dental Center in Lima during the period of January to March 2021 was determined. An observational, analytical, and cross-sectional study was designed, including 91 adult patients. The insertion of the labial frenulum was visualized in each patient by extending the upper lip and observing the position of the gingival margin in relation to the cementoenamel junction. Frequency analysis and contingency tables were performed to present the findings. It was found that 55 patients had a mucosal frenulum (60.4%), 33 had a gingival frenulum (36.3%), and 3 had a papillary frenulum (3.3%), with no cases of transpapillary frenulum. 49 patients had at least one gingival recession (53.8%), and 42 did not (46.2%). 14 men had gingival frenulums (42.4%) and 36 women had mucosal frenulums (65.5%). 30 mucosal frenulums presented teeth with at least one gingival recession, and 19 gingival frenulums had some recession. The study concluded that mucosal labial frenulums were the most frequent, followed by gingival frenulums, and papillary frenulums were the least frequent. No significant relationship was found between the types of mucosal frenulums and the sex and age of the patients evaluated.

Se determinó la relación entre los tipos de frenillos labiales superiores y la presencia de recesiones gingivales en los pacientes adultos del Centro Odontológico Rehabilitoral, de Lima en el periodo enero – marzo 2021. Se diseñó un estudio observacional, analítico y transversal que incluyó 91 pacientes adultos. En cada paciente se visualizó inserción del frenillo labial a través de la extensión del labio superior y la posición del margen gingival respecto al límite amelocementario. Se realizaron análisis de frecuencias y tablas de contingencia para presentar los hallazgos. Se encontró que 55 pacientes tuvieron frenillo mucoso (60,4%), 33 con frenillo gingival (36,3%), 3 con frenillo papilar (3,3%), ningún caso de frenillo transpapilar. 49 pacientes tuvieron al menos una recesión gingival (53,8%), 42 no lo tuvieron (46,2%). 14 varones presentaron frenillos gingivales (42,4%) 36 mujeres presentaron frenillos mucosos (65,5%). 30 frenillos mucosos presentaron dientes con al menos una recesión gingival y 19 frenillos gingival tuvieron alguna recesión. Se concluye que los frenillos labiales mucosos fueron los más frecuentes, seguido de los frenillos gingivales; y en menor frecuencia los frenillos papilares. No se encontró relación significativa entre tipos de frenillos mucosos y el sexo y edad de los pacientes evaluados.
