Actual (reported)thickness of cementum
After instrumentations the teeth extractions (n=48) were done and the teeth were stored in the solution of NaCl. Upon extracting the teeth were sectioned perpendicularly to the root axis with a microtome (Leica, RM2245, Wetzlar, Germany) between 10 and 15 µm thickness and stained with hematoxylin and eosin (Leica Autostainer XL, Wetzlar, Germany). Two horizontally root sections of each tooth were taken from coronal and apical part of instrumented area for a total 96 histologic specimens. Coronal sections were taken 1 mm apically from the gingival margin, whereas apical sections were taken 1 mm coronally from the endpoint of periodontal pocket. The teeth were examined by an optic microscope (Nikon Eclipse i5, Tokyo, Japan) connected to a camera (Nikon, DS-Filc, Tokyo, Japan) and finally to a dedicated computer. The thickness of the cementum was measured by a specific software (Nikon, NIS Elements 4.0, Tokyo, Japan).
within the first 60 days after extractions
Remaining calculus index (RCI) with SEM evaluation
within 30 days after extractions
Roughness Loss of Tooth Substance Index (RLTSI) with SEM evaluation
within 30 days after teeth extractions
Prior to extraction, the teeth (N = 12) were randomly included into ultrasonic instrumentation (Air Flow Master Piezon®, EMS SA, Nyon - Swiss) treatment group
Prior to extraction, the teeth (N = 12) were randomly included into hand curette (Gracey curettes, American Eagle, Missoula, MT, USA) treatment group hand instrumentation (Gracey curettes 5/6, 11/12, 13/14 American Eagle, Missoula, MT, USA)
comparison of different instruments on root cementum: Instrumentations with US devices ( Air Flow Master Piezon®, EMS SA, Nyon, Swiss) were performed with medium power settings and with the use of water cooling (as instructed by the manufacturer). One approximal root surface (distal and mesial) of each tooth was randomly subjected to debridement and the other approximal surface was used as control. All the instrumentations of teeth were performed by a single operator. The criteria for adequate treatment were smooth, hard root surfaces, with no remnants of calculus. The cleanliness and smoothness of the root surface were checked using a fine dental explorer. The instrumentations were done under local anesthesia.
