Abstract: Background
Incisive papilla has been used as a fixed anatomical landmark to guide in teeth
arrangement.
Objective
To assess the relationship of distance from central incisor to incisive papilla with
various types of arch forms, shapes of incisive papilla and types of canine-papilla-
canine relation.
Method
Two hundred maxillary stone casts were prepared. Eighteen casts were excluded
as they had voids and the final study was carried out in 182 participants. The arch
form was assessed according to Testut L. and shape of incisive papilla was recorded
according to Filho IE et al. A digital Vernier caliper was used to measure the distance
from posterior point of incisive papilla to the mesio-incisal edge from the labial side
of maxillary central incisor. The inter-canine line was drawn and its position with
incisive papilla was assessed. The analysis was done using SPSS version 20.0. One
way ANOVA was done.
Result
Result showed that parabolic type of arch was the most common i.e. 76.4%. Mean
distance of central incisor to incisive papilla was 11.093±1.894 mm. No significant
difference was observed in the distance of Central incisor to Incisive Papilla among
different arch forms (p=0.854) and various shapes of incisive papilla (p=0.091). The
mean distance of central incisor to incisive papilla was significantly greater when
canine-papilla-canine line passed from the middle than from posterior part of
incisive papilla.
Conclusion
These results suggest that incisive papilla is a reliable biometric guide which would
help to reduce the clinical time of both the dentist and the patients in placement of
the anterior teeth.
