Abstract:
OBJECTIVE: The present study investigated the possible impacts of anti-epileptic drugs (AEDs) on trabecular and cortical bone in the mandible. STUDY DESIGN: Fractal dimension (FD) and the radiomorphometric parameters of mandibular cortical width (MCW), panoramic mandibular index (PMI), and mandibular cortical index (MCI) were assessed on 497 dental panoramic radiographs (DPRs) of patients in the case group and controls. AEDs were compared according to 3 generations, duration of use, and patient age and sex. RESULTS: FD of the angle and body of the mandible and MCW were significantly lower in the case group than in the control group (P < .001). FD values in the ramus and angle were lower in first-generation and third-generation AEDs than in second-generation drugs (P ≤ .011). FD in the mandibular body was lower in first-generation and second-generation AED users than in third-generation drugs (P = .017). Drug use for at least 1 year resulted in significantly lower values for all FDs and MCW values and more class 3 MCI assessments than short-duration use, but PMI was higher with more than 1 year of AED use (P ≤ .020). Age and sex had no significant effects. CONCLUSIONS: AEDs caused significant changes in bone compared with controls in some FD values, MCW, and MCI. The effect of drug generation is pronounced in trabecular bone. Anti-epileptic drug use for more than 1 year had a greater effect than short-term use.
