“…Podshadley and Harrison13 in their research work on rat connective tissue response for rough and smooth restorative surfaces reported that unglazed porcelain surface in tissue contact can arouse an adverse tissue response. While Henry et al9 after comparative evaluation of the tissue changes beneath the fixed partial denture among different restorative materials concluded the most hygienic surface is glazed porcelain.…”

PURPOSEThe aim of this study was to evaluate the efficiency of manual polishing over autoglazed and overglazed porcelain and their effect on plaque accumulation.MATERIALS AND METHODSThirty-six porcelain discs were fabricated out of which 18 each was subjected for autoglazing and overglazing. Half surface of the discs was left intact; the remaining half was roughened with medium grit diamond bur. Roughened surfaces were repolished by porcelain polishing kits (Shofu, DFS, Eve). All the surfaces were evaluated by the perthometer and SEM. Six discs from each sample were placed in human volunteer's mouth for 72 hours to evaluate the plaque accumulation. Acquired data was subjected to ANOVA comparative evaluation.RESULTSRoughened surfaces had average roughness value of 2.88±0.1935 µm. The repolished surfaces by porcelain correction kits Shofu, DFS and Eve, average roughness value reduced to 0.6250±0.1036, 0.9192±0.0953, 0.9017±0.1305 respectively. Autoglazed and overglazed surfaces showed the mean roughness value (Ra) of 0.4217±0.0685, 0.3450±0.0729. SEM study showed the improved surfaces when subjected for polishing. Plaque accumulation percentage was the highest on roughened surface (93.83±6.2552%), followed by porcelain discs polished by commercial kits. Autoglazed surfaces found to be the best surfaces with the least plaque accumulation (0.5237±0.4209%).CONCLUSIONAll the polishing kits used in the study reduced the average roughness by approximately 77%. Corrected porcelain surfaces should ideally be reglazed, alternatively, polish the surfaces before final cementation.

“…Plaque control is crucial for the prevention of inflammatory periodontal disease . Smooth surfaces are preferred for optimal biocompatibility of restorative materials because rough surfaces have been demonstrated to promote plaque retention and mechanically irritate adjacent soft tissues . Mechanical rotary or oscillating instruments, hand instruments, and ultrasonic scalers have been shown to be effective for plaque removal .…”

“…It is therefore important to consider various ceramic finishing and polishing systems to recreate the lost smoothness of the abraded ceramic surface to obtain maximum biocompatibility. [65][66][67] It is a well-recognized fact that improved esthetic results are achieved by polishing, and the ultimate goal of finishing and polishing ceramics is to obtain a surface that can serve as a substitute of a glazed porcelain so that wear of the opposing dentition and restoration could be reduced. [68][69][70] However, it is important to differentiate between surface integrity and a quantitative measure of surface smoothness.…”

Advancements in all-ceramics for dental restorations and their effect on the wear of opposing dentition

Tooth wear is a process that is usually a result of tooth to tooth and/or tooth and restoration contact. The process of wear essentially becomes accelerated by the introduction of restorations inside the oral cavity, especially in case of opposing ceramic restorations. The newest materials have vastly contributed toward the interest in esthetic dental restorations and have been extensively studied in laboratories. However, despite the recent technological advancements, there has not been a valid in vivo method of evaluation involving clinical wear caused due to ceramics upon restored teeth and natural dentition. The aim of this paper is to review the latest advancements in all-ceramic materials, and their effect on the wear of opposing dentition. The descriptive review has been written after a thorough MEDLINE/PubMed search by the authors. It is imperative that clinicians are aware of recent advancements and that they should always consider the type of ceramic restorative materials used to maintain a stable occlusal relation. The ceramic restorations should be adequately finished and polished after the chair-side adjustment process of occlusal surfaces.
