Comparative study on the results of non-surgical periodontal treatment according to the location of the affected site

ABSTRACT

PURPOSE: The present study was performed to compare the treatment outcomes of non-surgical periodontal treatment according to the distribution of attachment loss of a given patient. METHODS: Forty-five patients with moderate to severe periodontitis were divided in two subgroups; Group I patients with teeth manifesting attachment loss of > or =6 mm at one or more sites on the buccal/labial aspect while maintaining an attachment level or =6 mm at more than one site on the lingual/palatal aspect while maintaining an attachment level or =6 mm at buccal/labial surfaces responded better to the nonsurgical periodontal therapy than those demonstrating comparable attachment loss at lingual/palatal surfaces.
