"Differences of Annual Radiographic Periodontal Attachment levels among Periodontitis Disease Groups for Periodontal Treatment with and without using the TPP splint"

The aim of the present study was to assess the differences annual radiographic periodontal attachment levels (ARPAL) of treatment for periodontal treatment of teeth with and without using the TPP splint over 5 years or more. A total of 53 subjects, who had taken two sets of full-mouth periapical paralleling radiographs with separated periods of 5 years or more in the hospital were collected for the past 20 years. The radiographic periodontal attachment levels at mesial and distal aspects of teeth were assessed by measuring the distance between cementoenamel junction (CEJ) and the bone crest using an electronic digimatic caliper (EDC) under a 3.5X magnified dental x-ray radiographs. Results revealed that there was a remarkable gain of ARPAL and significant (p<0.001) (+0.100.19 mm/yr.) in the treatment of teeth with TPP splint as compared to the bone loss (-0.050.13 mm/yr.) those teeth without TPP splint, respectively. We concluded that here was a significant attachment level gain in the teeth with TPP splint as compared to the teeth without TPP splint.
