The effect of tetracycline hydrochloride on the smear layer
formed by various root planing modalities: A scanning
electron microscopy study
Nadir Babay, DDS, MS, DESM
The purpose of the present study was to examine the smear layer formation following different root planing modalities and its removal using tetracycline hydrochloride. Thirty-two periodontitis involved human teeth were randomly divided into 8 groups of 4 each.
Groups 1 & 2 were root planed with hand instrument (Gracey 11/12) while in groups 3 & 4, aflat diamond bur was used. In groups 5 & 6, the roots were scaled with a piezoelectric unit (Piezon) while in groups 7 & 8, a magnetostrlctive unit (Amdent) was used. Sixteen teeth (two in each group) were conditioned with tetracycline hydrochloride for 3 minutes while the other sixteen teeth were not conditioned and served as controls. The surfaces were examined by a scanning electron microscope. The results showed that root planing resulted in a smear covering the root surfaces, irrespective of the treatment modality. Tetracycline hydrochloride efficiently removed the smear layer with collagen fibers exposed to varying degrees.
