“…The specificities at D 1 (all visible lesions affecting enamel) and D 3 (lesions extended into dentin) were, respectively, 0. 41 In dental practice, secondary caries is defined as a lesion that occurs at the margin of an existing restoration, and it is the most common reason for filling replacement. [1][2][3] Histopathologically, caries lesions around restorations may show lines of demineralized tissue along the cavosurface margin (called outer lesions) and the cavity wall (called wall lesions).…”

To evaluate the in vitro performance of the International Caries Detection and Assessment System (ICDAS) visual examination, bitewing radiography (BW), and the DIAGNOdent 2190, a pen-type laser fluorescence device (LFpen), in detecting caries around amalgam restorations on approximal surfaces. Approximal surfaces (N=136) of permanent posterior teeth (N=110) with Class II amalgam restorations were assessed twice by two experienced examiners using ICDAS, BW, and LFpen. The occurrence of proximal overhangs was also evaluated. The teeth were histologically prepared and assessed for caries extension. Different cutoff limits for the LFpen were used. Intraexaminer and interexaminer reproducibility showed moderate to good agreement for all the methods (weighted κ/intraclass correlation coefficient=0.40 to 0.87). The specificities at D1 (all visible lesions affecting enamel) and D3 (lesions extended into dentin) were, respectively, 0.41 and 0.82 for ICDAS, 0.70 and 0.82 for BW, and 0.77-0.89 and 0.88-0.94 for LFpen. The sensitivities were 0.80 and 0.52 for ICDAS, 0.56 and 0.51 for BW, and 0.04-0.23 and 0.01-0.02 for LFpen at D1 and D3, respectively. At the D1/D3 thresholds, the accuracy and the area under the receiver operating characteristic curve (Az) values were similar and statistically higher for ICDAS (0.65/0.68 and 0.633/0.688) and BW (0.64/0.68 and 0.655/0.719), respectively; whereas, LFpen presented lower accuracy (0.37-0.44/0.49-0.52) and Az (0.390-0.454/0.345-0.395) values. The occurrence of overhangs (26.8%) was shown to be irrelevant in determining the presence of secondary caries. The ICDAS and BW methods presented the best performance in detecting caries lesions affecting enamel and dentin on approximal surfaces of amalgam restorations.

“…Although an obvious assumption, many are the obstacles that are encountered in the way towards a complete integration of the artificial crown in the dental/periodontal environment. In recent years, many evidences demonstrating that the presence of a fixed prosthetic restoration enhances the risk of the onset of periodontal lesions have been collected [2,6]. The awareness of the importance of an abnormal subgingival microbiota in the etiology of periodontal disease and that of adhesion to the hard tissues in dental plaque formation inspired studies aimed to identify materials that were less prone to bacterial colonization [7][8][9] and more suitable to reconstruct normal dental anatomy [1,5].…”

“…In dentistry, prosthetic restorations are generally intended for long-term durability without causing any damage to the tooth and surrounding tissues [1][2][3][4][5].

“…A dental prosthesis is successful only if the restoration remains in place over a long time and without causing any disease [1][2][3][4][5]. However, many evidences that show the existence of a close relationship between the presence of fixed prosthetic restorations and an enhanced risk of periodontal infections have been collected [2,6].…”

“…However, many evidences that show the existence of a close relationship between the presence of fixed prosthetic restorations and an enhanced risk of periodontal infections have been collected [2,6]. A lot of researches were consequently addressed at studying different dental materials with respect to their susceptibility to colonization by selected bacterial species [7][8][9], their surface characteristics, and many technical aspects related to the possibility to reconstruct normal dental anatomy [1,5].…”

Microbiological and host factors are involved in promoting the periodontal failure of metaloceramic crowns

This study was aimed at looking into the microbiological/inflammatory parameters predicting the periodontal success/failure of fixed prostheses. Microbiological and inflammatory patterns were studied at 102 sites having metaloceramic crowns in place from 3 to 6 years and divided in healthy sites (HS), gingivitis affected (MG), and periodontitis affected (PB). Total bacterial flora and selected indicator species in subgingival plaque were quantified by quantitative real-time PCR. The concentrations of IL-1β, IL-6, and TNF-α were determined in gingival crevicular fluid (GCF) by enzyme-linked immunosorbent assays. The experimental sites showed no significant difference with respect to the age and gender of the patients and to the position of the crown margins. Poor marginal adaptation was significantly higher in MG and PB. The total amounts of bacteria per probing depth showed no significant differences among the three groups and their controls, while both MG and PB sites showed altered patterns in the distribution of specific bacteria. Both MG and PB sites showed significantly higher levels of inflammatory cytokines in GCF. The control teeth of PB subjects showed significantly higher levels of IL-1β as compared to other control sites. Data confirm that the application of metaloceramic crowns is a factor of risk for the development of gingival/periodontal inflammation. This risk is possibly associated with microbiological and host factors that predispose to the onset of periodontal alterations at sites reconstructed with metaloceramic crowns. These factors, once their role is confirmed by longitudinal studies, could be used to set up rapid tests to early predict the onset of periodontal disease at reconstructed sites.

An adequate understanding of the relationship between periodontal tissues and restorative dentistry is paramount to ensure adequate form, function, esthetics, and comfort of the dentition. While most clinicians are aware of this important relationship, uncertainty remains regarding specific concepts such as the biologic width and indications and applications for surgical crown lengthening. This review discusses the concept of the biologic width and its relationship to periodontal health and restorative dentistry. The importance of restorative margin location, materials, and contours related to periodontal health is also addressed. The rationale and indications for surgical crown lengthening are elaborated. Particular surgical principles of crown lengthening are examined in detail.
