# Influence of inter-proximal dimensions on inter-dental papilla presence

## TL;DR

This study found that the presence of interdental papilla is strongly influenced by the vertical and horizontal distances between adjacent teeth.

## Contribution

The study provides new empirical evidence linking inter-proximal dimensions to the presence of interdental papilla.

## Key findings

- Inter-dental papilla were present in 88.9% of cases when vertical distances were 4 mm.
- Papilla presence reached 95.7% to 100% when horizontal distances were between 0.5 and 1 mm.
- Both vertical and horizontal distances significantly influence papilla presence, either separately or in combination.

## Abstract

The presence of interdental papilla in relation to vertical distance between alveolar crest and the contact point, as well as
horizontal distance between adjacent roots is of interest to dentists. Hence, 50 patients with a total of 501-papilla were examined.
Following extensive debridement, mucoperiosteal flap was reflected and measurements of horizontal and vertical distances between
adjacent roots were taken. Prior to reflection, each papilla was also given a JEMT index score. Linear trend analysis was done using
χ2 test to examine the incidence of papilla and in 88.9% of cases, inter-dental papilla were found when vertical
distances was 4 mm (P<0.01). Additionally, when horizontal distances were between 0.5 and 1 mm, papilla were present in 95.7% to 100%
of cases (P<0.01). Thus, the presence of inter-proximal papilla was significantly influenced by vertical and horizontal distances of
inter-proximal areas, both separately and in combination.
