Abstract

Introduction: Black angle (Latin: Angularis Nigra), also known as open gingival embrasures, and colloquially known as "black triangle", is the space or gap seen at the cervical embrasure, below the contact point of some teeth. The gingival black triangle does not only play a role in aesthetic concerns but also may cause plaque accumulation, further worsening periodontal disease, and phonetic problems.

Aims: The purpose of this study was to determine the prevalence of posttreatment black triangles in adult orthodontic patients and to examine the association of sex, type of malocclusion, and treatment plan with open gingival embrasures.

Materials and Methods: About 3500 patient records from three dental colleges were reviewed. A sample of 173 subjects was obtained and was used to determine the prevalence of black triangles in adult patients after orthodontic treatment. The data obtained were analysed using the chi-square test. The statistical analysis in this study was done using SPSS software.

Results: The mean age of the population included in the study was 22.61 ± 4.47 years. The prevalence of black triangles was 1.73% before orthodontic treatment in the selected study sample. The same sample showed prevalence rate of 36.42% post orthodontic treatment

Conclusions: In an average Indian adult orthodontic population, 36.42% of patients had open gingival embrasures after treatment.
