Abstract
Introduction:
Torus mandibularis or mandibular tori is a benign exophytic bony osseous outgrowth seen in the lingual side of the
mandible. They are asymptomatic, slow-growing, self-limiting and painless exophytic growth but it is feasible for
any formation of ulcer on the tori as a consequence of any trauma.
Aim:
To assess the incidence of mandibular tori in patients visiting a dental college in Chennai
Materials and Methods:
This retrospective study was conducted in a university setting. A total of 535951 treatment records were assessed for
the study. Simple random sampling was done to minimise the sampling bias. Data were collected from n=88 patients
with Torus mandibularis during the year 2019-2020. All the data were calculated and tabulated in MS Excel. The analysis is done by using SPSS software version 23, Chicago, descriptive statistics and chi-square tests were
performed with the level of significance at 5% (P<0.05).
Results:
In our present study, a total of 88 cases of mandibular tori were included of which 72.73% were males and 27.27%
were females. The types of mandibular tori were also observed in these patients, 40.91% were presented as bilateral
solitary, 17.05% were bilateral multiple, 23.86% were bilateral combined, 11.36% were unilateral solitary and
6.82% of mandibular tori were unilateral multiple. On the correlation between the age of the patients and the types
of mandibular tori observed a Chi-square test was done and no significant association was found between the age of
the patients and mandibular tori, P-value = 0.610, P=>0.05, even though a higher percentage of 13.64% of the
bilateral solitary type mandibular tori observed among the age group of 41-50.
Conclusion:
In our study, the incidence of mandibular tori was relatively low in our observed population with a higher male
predominance (72.73%). Our study also found that mandibular tori incidence is higher in middle age groups
(27.27%) and low in older ages (10.23%).
