Prevalence of Oral Vascular Lesions in Patients Referred to the Oral Medicine Department of Shiraz Dental School During 2001-2017

Assessing the common oral lesions and their prevalence is important in different populations. This study assessed the prevalence of oral vascular lesions in patients referred to the Oral Medicine Department of Shiraz Dental School.  

In this cross-sectional study which was conducted in Shiraz Dental School, records of patients admitted from 2001 to 2017 were reviewed. A total of 176 patients had been diagnosed with oral vascular lesions. The mean age and gender of patients and the prevalence of vascular lesions were recorded and analyzed. Associations between the variables were explored using the Chi-square test and Kruskal-Wallis test. P<0.05 was considered statistically significant.

  A total of 176 patients had oral vascular lesions among 3,896 clinical patient records during the 16-year period (2001-2017). Of the 176 patients, 108 (61.4%) were females and 68 (38.6%) were males. The mean age at presentation was 36 ±4.5 years with an overall age range of 4-88 years. Amongst all the evaluated oral lesions, the most prevalent vascular lesion was pyogenic granuloma with 124 (3.18%) patients. Other vascular lesions were vascular malformations (n=27, 0.7%), hemangioma (n=19, 0.49%), and lymphangioma (n=6, 0.15%). There was no significant correlation between gender with vascular lesions (P=0.078) or location of lesions (P=0.143). No significant correlation was found between age with type of vascular lesion (P=0.174) or site of involvement (P=0.281).

  Among oral vascular lesions, pyogenic granuloma was found to be the most prevalent lesion in the oral cavity.
