Introduction: Grinspan syndrome is a triad of erosive form of oral lichen planus (OLP), diabetes mellitus (DM) and arterial hypertension. The objective of present study is to evaluate the oral health and oral symptoms in patients with Grinspan’s syndrome and also an emphasis on evaluating the level of awareness about oral health in patients of this disease complex. Methods: The study subjects with Grinspan’s syndrome are included in the study while the rest were excluded along with those who are on medications for other conditions. A self-administered structured questionnaire is used as the survey instrument. After collecting all the responses from patients, it is analyzed statistically using IBM SPSS® Software (21.v). Results: The most common oral symptom found in Grinspan’s syndrome is Glossodynia (92.1%). The high arched palate (35.6%) and temporomandibular joint disorders (35.6%) are least associated with this syndrome. Glossodynia was most prevalent (91.4% and 93% respectively) and their association with gender was highly significant (p value<.001) however the association of all other oral symptoms with gender was statistically non significant (P>.001). Among the different age groups, the presentation of oral symptoms was highly variable but the association between oral symptoms and age group was statistically highly significant (P<.001). Conclusions: Glossodynia is the most common oral symptom found in Grinspan’s syndrome whereas high arched palate and temporomandibular joint disorders (35.6%) are the least associated with this syndrome, in our study. The presentation of oral symptoms depends on and varies according to the age group of patients.
