About this trial
The purpose of this retrospective radiographic study is to evaluate the effects of long-term H1 antihistamine use on mandibular trabecular bone structure in children aged 8-10 years. Mandibular trabecular bone will be assessed using fractal dimension analysis and the panoramic mandibular index on digital panoramic radiographs. Three groups will be compared: children receiving long-term H1 antihistamine therapy, allergic children without antihistamine use, and age- and sex-matched healthy controls. The findings will provide information on whether long-term antihistamine therapy is associated with alterations in mandibular bone microarchitecture.
