Prevalencia de la Pérdida de Inserción Clínica en Adolescentes de Colegios Públicos de Medellín-Colombia

Abstract

Background and AimsData on periodontal conditions in adolescents living in Medellin, Colombia are scarce. The aim of the present study was to estimate risk indicators and the prevalence of clinical attachment loss using multivariable logistic regression. MethodsA random sample of the Colombian adolescents was obtained, comprising 629 subjects. A probability, weighted sample was selected using a complex, multistage probability sampling design. The study was clustered in schools and classrooms. The study subjects were clinically examined under field conditions by a single calibrated examiner who measured gingival recession and recorded probing depths at six different sites per tooth, with subsequent calculation of clinical periodontal attachment level for each site. ResultsThe prevalence of clinical attachment loss ≥1mm in the sample was 40.6%; with a prevalence range between 26.5% and 55.3%, depending on age and gender. Clinical attachment loss ≥2mm was found in 29.9% of the students and attachment loss ≥3mm was seen in 16% of the students. The logistic regression model revealed that only gender significantly increased the probability of having clinical attachment loss. ConclusionsThis study shows the prevalence of clinical attachment loss in adolescents in Medellin and proves that gender is associated with a higher odd ratio of clinical attachment loss.
