Periodontal conditions in patients 5 years following insertion of fixed prostheses

Abstract

The oral hygiene, gingival condition, pocket depth and loss of attachment were studied during a period of 5 years in a group of patients (114) who had been treated with fixed dental protheses. Eighty-four per cent of the subjects had received periodontal therapy prior to the prosthetic treatment. During the study the subjects participated in an oral hygiene programme. Crown margins were located sub-gingivally, at the gingiva, and supra-gingivally. Initially 65% of the crown margins were sub-gingival compared to 41% 5 years later. When the crown margins were located sub-gingivally there was an increase in Gingival Index scores 2 and 3, in pocket depth, and in loss of attachment compared to a supragingival placement. However, most of the alterations were small.

The influence of some iatrogenic factors on a cytomorphometric analysis of gingival cells and periodontal status among diabetic patients

“…The inappropriate prosthodontic treatment assists the appearance of arrogance pathological changes in periodontal tissues based on the roughness, surface status of the crown margins that participate in plaque accumulation and gingival tissue inflammation 24 .On the other hand, in the experimental study on patients were followed up 5 years after part of fixed prosthesis there were increases in pocket depth more than the control group 25 and clinical attachment loss was reported in other longitudinal studies that extended from 1 to 1 5 years where the meaning of attachment loss was from 0.1 5 to 1.3 mm during this study 25,26,27 these findings similar the results of the current study where there were increases in PLI, GI, and CAL in GIII compared GI. On the other hand the GI of GII and GIII more than GI but it was more in GIII than GII furthermore, there were significance differences in CAL in our study where it was more in GIII and GII than GI but it was more in GIII than GII.…”

Crowns and other extra-coronal restorations: Aesthetic control

“…Where the margins are not visible, there are good biological arguments for placing all margins supra-gingivally. 4 These sites would include all margins on molars, lingual and interproximal sites, and buccal aspects of anteriors and premolars where functional lip positions obscure the gingival margin. Not only will this facilitate finishing and maintenance but should also favour periodontal health.…”

Radiographic assessment of the quality of dental restorations and their relationship with periodontal radiographic changes

“…As a rule, all restorative procedures should only be performed after examining clinical and radiographic periodontal structures. Untreated periodontal disease can compromise the success of restorative therapy and inadequate restoration can lead to an iatrogenic effect on periodontal tissues [1][2][3].…”
