The aim of this study was to determine the prevalence, and shape of TP and TM in relation to age and sex in Iranian population. Methods: The present study included 613 subjects (458 men and 389 women) with mean age of 43.31±16.87 years. The subjects were examined for the existence of tori by clinical inspection and palpation. Statistical analysis was performed using SPSS 22.0 software program. Findings: Among the 106 subjects with tori, 8 (7.55%) had either TP or TM. 41 (38.68%) subjects had TP, whereas 57 (53.77%) had TM. The maximum percentage of TP, TM, and either tori was observed in the age-group of 49–59 years, the oldest group (59 and older years age range), and the age-group 49-59 years. The percentage of females with tori was higher when compared to males, which is however not significant. According to shape, the occurrence of flat-shaped TP (41.46%) and bilateral solitary TM (42.11%) was more common. Conclusion: This study indicated that the prevalence of TP in Iranian population was 17.29%. No significant difference in the presence of tori with respect to sex and age was observed. According to the literature, flat TP and bilateral solitary TM were the most common type in our population. M3 ER -
