Pattern of bone loss between smoker and non smoker patients

The aim of this study was to evaluate the pattern of bone loss found between smoker and non smoker patients who attended dental OPD. Pattern of bone loss was evaluated on the basis of horizontal, vertical and angular defect by taking OPG and peri-apical radiographs. 1500 patients were examined and treated from February 2008 to January 2009 by completing periodontal evaluation forms and measuring pocket depth. It was noted that patients who were smokers developed more bone loss in comparison to non smokers, but it was found out that both smoker and non smoker patients developed more horizontal pattern of bone loss in contrast to other bony defects
