Objective: Antihypertensives, anticonvulsants, and immunosuppressants can cause gingival overgrowth (GO). Drug-induced gingival overgrowth (DIGO) is a notable oral health issue. This study aimed to assess physicians' awareness of DIGO, evaluate the impact of medical training, and provide a broader perspective on the topic.

Materials and Methods: This study was conducted with the participation of 249 specialists and general practitioners working throughout Türkiye who volunteered to participate in the study. Data were collected via a Google Forms questionnaire shared through WhatsApp. The survey included yes/no and multiple-choice questions assessing knowledge and attitudes toward DIGO.

Results: While 96% of participants considered drug side effects when prescribing, only 43.4% were aware of drugs causing GO. For drug groups associated with GO, 11.2% identified antihypertensives, 7.6% anticonvulsants, 3.2% immunosuppressants, and 94% selected all. Significant associations were found between DIGO knowledge and age, experience, and specialty (p<0.05).

Conclusion: Although general awareness of DIGO was present, knowledge about causative drugs and patient management was limited. Despite its prevalence, DIGO was rarely encountered in practice, suggesting underrecognition. It is assumed that there is a need for multi-center studies with larger participants to measure the level of knowledge.
