The Relationship Between Restoration and Furcation Involvement on Molar Teeth

Abstract

The purpose of this cross-sectional study was to examine the correlation between the presence of a crown (CR) or a proximal restoration (RE) and furcation involvement (FI) on molar teeth. Data were collected from 134 periodontal maintenance patients who had restored and non-restored molars present both with and without FI. A majority of the restorations that were present in these patients had been in place for at least 5 years prior to the study. First and second molars were examined clinically using the following criteria: CR, RE, FI, mobility (MO), and probing periodontal attachment level (AL). Data were analyzed with a statistical program utilizing Pearson chi-square and the pair-difference t test. The results indicated that molars with CR or RE had a significantly (P < 0.01) higher percentage of FI but no greater mobility when compared to molars without restorations. Mean probing periodontal attachment loss was greater for restored than non-restored molars but only with marginal significance (P = 0.051). There was a greater difference in mean AL between restored versus non-restored maxillary molars than for mandibular molars. This cross-sectional study provides evidence that molars with crowns or restorations involving the proximal tooth surfaces had a higher prevalence of FI and greater AL than molars without restorations.

A retrospective clinical, radiographic and microbiological study of periodontal conditions of teeth with and without crowns

“…Other studies 8 showed higher values of CAL in subgingivally located restorations, independently of the observed adaptation. Although showing higher values of CAL for crowned teeth, Wang et al 17 (1993) did not find statistically significant differences between crowned and sound teeth. The outstanding study of Schätzle et al 13 (2001), that evaluated 160 patients during 26 years, did not find statistically significant differences between the study groups, similarly to the results of the present study.…”

Necessidade de tratamento periodontal avaliada pelo CPITN e sua relação com a qualidade de acabamento cervical das restaurações

“…ARNEBERG et al 4 , perda de inserção 3,8,11,23 , reabsorção óssea e lesões de bifurcação 23 . Este processo patológico é decorrente do acúmulo de placa bacteriana em regiões onde o seu controle muitas vezes é impossível de ser realizado; bem como de alterações na microbiota periodontal 10 .…”

Biologic Perspectives in Restorative Treatment

“…Clinically it could manifest as gingival bleeding and periodontal pocket formation. Histological and clinical investigations of periodontal tissues response to restorations with margins altering gingival biological width confirmed these statements [6][7][8][9][10][11][12][13][14]. It is established that minimal width of 2 mm is needed for gingiva to attach to the bone.…”
