Prevalence of Unilocular Radiolucencies among a Subset of Indian Population - A Retrospective Study

Author(s): Jayanth Kumar Vadivel*


Unilocular appearance usually indicates a benign, slow-growing condition that is not aggressive. Corticated / non-corticated borders, regular / irregular borders, root displacement, root resorption, mandibular canal displacement, and lingual cortex expansion are all radiographic findings that are equally important. Aggressive benign or malignant lesions are more likely to have uneven and non-corticated borders, lingual cortex growth, resorption of surrounding tooth roots, and erosion of the mandibular canal, resulting in paresthesia.

Materials and Method

It is a single centre retrospective study in a private dental institution, Chennai. The samples were taken from the patients who checked in from June 2019 to March 2021, Reported to the dental hospital with halitosis. The data was collected, verified, tabulated and analysed using SPSS by IBM version 2.0, the Chi square Test was performed to compare the data and check for its distribution.

Result and Discussion

From the study results we can observe that unilocular radiolucencies are more prevalent in males. It was seen that unilocular radiolucencies are more common in the mandible compared to the maxilla. The most common unilocular lesion was periapcal cyst followed by dentigerous cyst.


This study concludes that unilocular radiolucencies are not as common as multilocular radiolucencies and periapcal cyst being the most common type of unilocular radiolucency seen.
