Is there any difference based on sublingual varices frequency between hypertensive patients and healthy persons?

Sublingual varices (SV) are benign vascular lesions that have questionable associations with aging, smoking, and hypertension. This study purposed to evaluate whether SV frequency differs between hypertensive patients and healthy persons.

This cross-sectional study was conducted on 120 dental patients referred to Yazd Oral Medicine Department. At first sublingual surface of the tongue were examined before the routine oral survey, and blood pressure (BP) was measured in a sitting position. SV were classified into Grade 1 (no/mild), Grade 2 (medium to severe), and Grade 3 (multi-focal). Blood pressure was measured in all participants. Participants based on the obtained BP, divided into normal, prehypertension, stage 1, and 2 groups. Frequency of SV was compared in regarding age, gender, and stage of hypertension. All of the analyses were conducted at a p < 0.05 level of significance by the SPSS22 statistical package using chi-square test.

Out of 120 patients, 84 (70%) had SV. The frequency of SV in patients with hypertension (HT) (86.8%) was significantly higher than in others (48.1%); (p < 0.001). Data analysis showed there was a significant difference between the age groups. There was no significant difference based on SV between two genders. There was no significant difference in the frequency of sublingual varices between males and females. Aging could impact the frequency of SV.

This study revealed that patients with hypertension had more SV. A simple valuable method for dental clinicians to be active in preventive health care is evaluating sublingual surface of tongue.
