In recent years many risk factors have been implicated in the etiology of destructive periodontitis. The quality of the previous dental works might play a decisive role in the development of periodontal attachment loss. The main objective of the present clinical study was to evaluate the aggravating role of the subgingival restorations with questionable quality and the interproximal untreated carious lesions in the progression of periodontal attachment loss in a randomly selected group of patients with destructive periodontitis. The panoramic radiographs of 170 randomly selected patients suffering with destructive periodontitis were analyzed and the quality of the approxima restorations, the presence or absence of interproximal untreated carious lesions and the interdental bone loss were recorded. The level of interproximal bone around the teeth with restorations or with approxima carious lesions were compared with the sound contralateral counterparts and with the overall average alveolar bone level. Some more than 50% of 2175 approxima restorations were faulty. 280 untreated carious lesions were present in 170 subjects. The interproximal bone loss was always greater around teeth with untreated carious lesions or with faulty restoration. The differences between the control teeth and the carious teeth were statistically significant (P0.01) excepting the maxillary front and mandibular premolar region. The differences between the teeth with faulty restorations and the controls were statistically significant (P0.01) in the mandible and in the maxillary molar region. Although there were significant differences between teeth with untreated carious lesions or with faulty restoration and the controls in many regions of the dental arch, the differences clinically were not always necessarily significant, showing only less than 0.5 mm differences in bone levels, In conclusion the faulty restorations and untreated carious lesions do not seem to be decisive aggravating risk factors leading to bone loss in patients with chronic destructive periodontitis. |
