The study was designed to determine the relationship between lip prints and odontometric parameters of the maxilla among Igbomina people of Kwara state, Nigeria within age range 18-50years. 422 (211males and 211 females) participated in the research. The lip print was obtained by removing dirt with wipes and applying lip gloss on the lip evenly.Microscope slide was then placed on the lip with gentle pressure ensuring the mouth of the subject remained stationary for few seconds. The microscope slide was removed from the lip and carbon black was sprayedon the slide in little quantity to obtain the print. The odontometrics were measured using a digital vernier caliper and the mean value ofthe Intercanine width (ICW), interpremolar width (IPW) and mesiodistal dimension (MDD) of the left and right maxillary canine were established. Mean and SD were derived from the data obtained through statistical analysis and t-test was used to check for any sex association and statistical significance was put into consideration when (P≤0.05). Traditionally CHAID splits the lip prints into categories. The results of the study showed that type II was the most common lip print in both male and female among this population. Conversely, ICW of the maxilla has the highest sexual dimorphism than other odontometric parameters considered in this research. Also type II lip pattern of the ULQ and LLQ has a significant relationship with ICW of the maxilla. Conclusively, cheiloscopy and odontometrics, can be used jointly as a tool inpersonality identification in medico-legal contexts.
