Association between Signs of Trauma from Occlusion and Periodontitis

Abstract

The purpose of this study was to evaluate the association between signs of trauma from occlusion, severity of periodontitis and radiographic record of bone support. The maxillary first molars of 300 individuals were independently evaluated by two examiners for signs of trauma from occlusion, pattern or occlusal contacts and severity of periodontitis. Each site was also evaluated radiographically by an independent third examiner. The results indicated that: teeth with either bidigital mobility, functional mobility, a widened periodontal ligament space or the presence of radiographically visible calculus had a deeper probing depth, more loss of clinical attachment and less radiographic osseous support than teeth without these findings, teeth with occlusal contacts in centric relation, working, nonworking or protrusive positions did not exhibit any greater severity of periodontitis than teeth without these contacts, teeth with both functional mobility and radiographically widened periodontal ligament space had deeper probing depth, more clinical attachment loss and less radiographic osseous support than teeth without these findings and given equal clinical attachment levels, teeth with evidence of functional mobility and a widened periodontal ligament space had less radiographic osseous support than teeth without these findings.

Occlusal considerations in periodontics

“…6 The conformative approach is the safest way of ensuring that the occlusion of a restoration does not have potentially harmful consequences. 7…”

The Relationship of Trauma from Occlusion with Chronic Periodontitis Based on the Quality and Quantity of Alveolar Bone in the Radiographic Features

“…Philstrom also supports the results of this study where the purpose of this study was to evaluate the association between signs of trauma from occlusion, severity of periodontitis and radiographic record of bone support. The results show that there are teeth with widening of periodontal ligament space on the radiographic image [6].…”

“…The results showed that the non-working teeth showed no greater severity than those with periodontitis and clinically given the same attachment level, the teeth in the presence of functional mobility and widening of the periodontal ligament could be seen to have decreased bone support in radiographic features [6]. Furthermore, Lindhe who conducted the study to see the effects of trauma from occlusion and the periodontal status if the bacterial plaque factor was not included.…”

“…Each site was also evaluated radiographically by an independent third examiner. The results indicated that: (1) teeth with either bidigital mobility, functional mobility, a widened periodontal ligament space or the presence of radiographically visible calculus had deeper probing depth, more loss of clinical attachment and less radiographic osseous support than teeth without these findings, (2) teeth with occlusal contacts in centric relation, working, nonworking or protrusive positions did not exhibit any greater severity of Periodontitis than teeth without these contacts [6].…”

Role of trauma from occlusion in periodontal disease- A controversy

“…Human research studies reported from 1986-87 questioned the effects of occlusal forces on the progression of periodontitis (Hakkarainen 1986, Philstrom et al 1986, Houston et al 1987. [8][9][10] …”
