A study carried out in Karachi, Pakistan, yielded the same results showing frequency of torus palatinus as 3.7% of patients out of which 35.3% were males and 64.7% were females.10
However, a study conducted among edentulous patients in Saudi Arabia found male predominance, showing the percentage of males with either tori, higher (19.0%), when compared to females (15.94%).13 Another study conducted in Jordan reported the frequency of torus palatinus and Torus mandibularis as 3.1%, and 2.3% respectively.
Frequency of torus palatinus was found higher as compared to torus mandibularis.
Torus Palatinus and Torus Mandibularis: a review of the literature.
Key: n= total number of subjects TP= Torus palatinus
Out of 34 subjects having torus palatinus, 12 (35.3 Percent) were small, 15 (44.2 Percent) were medium and 7 (20.6 Percent) were large sized.
Whereas a study done in Turkey in 200828 reported greater num- ber of flat shaped tori ( 62.7 Percent) as by other studies cited in the literature.28-31 The same reasons may stand true for variety of results in this aspect of torus palatinus. Nutrional factors like consumption of higher unsatur- ated fatty acids and vitamin D have also been explored to have a role in bone growth, thus, affecting the results for prevalence, shape and size of tori.32
Oral tori in general and torus palatinus in particu- lar, complicate prosthetic treatment.
