Review
OBJECTIVE
To evaluate clinical performance of the new CAD/CAM resin-matrix ceramics and compare it with ceramic partial coverage restorations.
MATERIALS AND METHODS
An electronic search of 3 databases (The National Library of Medicine (MEDLINE/PubMed), Scopus, and the Cochrane Central Register of Controlled Trials) was conducted. English clinical studies published between 2005 and September 2020 that evaluated the clinical performance of CAD/CAM resin-matrix ceramics inlays, onlays, or overlays were selected. The primary clinical question was applied according to PICOS strategy (Population, Intervention, Comparison, Outcome, Study design). The included studies were individually evaluated for risk of bias according to the modified Cochrane Collaboration tool criteria.
RESULTS
A total of 7 studies were included according to the established inclusion and exclusion criteria. From the included studies, 6 were randomized clinical trials while one study was longitudinal observational study without control group. According to the results of the included studies, the success rate of CAD/CAM resin-based composite ranged from 85.7 to 100% whereas the success rate reported for ceramic partial coverage restorations ranged from 93.3 to 100%. Fractures and debondings are found to be the most common cause of restorations failure.
CONCLUSION
CAD/CAM resin-based composite can be considered a reliable material for partial coverage restorations with clinical performance similar to glass ceramic restorations. However, this result needs to be confirmed in long-term evaluations.
CLINICAL RELEVANCE
CAD/CAM resin-based composites provide a potential alternative to ceramic indirect restorations. However, clinicians must be aware of the lake of knowledge regarding long-term outcome.

Review
PURPOSE
Ceramic materials, first introduced in restorative dentistry in the late 18th century, offer a wide range of possibilities and exhibit esthetic properties. The last systematic reviews on the subject of ceramic inlays were published in 2003. All articles published up to 2001 were surveyed regarding the longevity, esthetic qualities, and postoperative discomfort associated with the use of ceramic inlays compared to other restorative materials. The present review aimed to establish the current state of the art.
MATERIALS AND METHODS
Using methods identical to those of previous reviews, the literature from 2001 up to and including 2009 was assessed. The scientific and methodologic qualities of all articles describing the use of ceramic inlays were established. Articles comparing the results of ceramic inlays to other types of inlays were then used to answer the hypotheses that there were no differences in longevity, postoperative sensitivity, or color match.
RESULTS
Three articles comparing the results of ceramic to other materials were analyzed further. No new reliable evidence was found to update the answer to the hypothesis that there was no difference in longevity, at least in the first year postoperative. The evidence found regarding postoperative discomfort backs the previous conclusion that there was no difference. New evidence found on color matching suggests that there is no significant difference in color match over assessment periods of up to 57 months.
CONCLUSION
Current ceramic materials in inlay restorations seem to perform as well as other restorative options for selected properties during the first years after placement.

Review
The aim of this systematic review was to evaluate the volumetric changes associated with different bone grafting techniques in the completely edentulous atrophic maxilla before dental implant placement. A search was performed according to the PRISMA guidelines. A PICO question was formed, and the PubMed, Scopus, Embase, and Cochrane Library databases were searched, covering the period 2000-2018. Relevant data were extracted from the results regarding study population, surgical details, technical information on volumetric data acquirement, and volumetric outcome after bone augmentation procedures before implant placement. Six articles with a combined population of 84 patients were included. All patients had a completely edentulous maxilla, with a crestal horizontal width of <3-4mm or a crestal vertical height of <6-7mm. The iliac bone and ascending ramus were most frequently used as grafts. Five of the six studies reported volumes of sinus inlay graft (SIG) and four reported volumes of lateral bone augmentation (LBA). Radiographic analyses of the augmented areas differed among the studies. Volume loss after bone augmentation procedures ranged from 5% to 50% for SIG and from 5% to 47% for LBA. All surgical augmentation techniques for the edentulous maxilla are prone to resorption; no procedure seemed to be superior, but some interesting observations were made.

Review
PURPOSE
The survival and performance of clinical prostheses with a ceramic component are probabilistic in nature. Only under very rare circumstances will all of the prostheses in a group exhibit either 100% successes or 100% failures over a period of 5 years or more. Prosthesis failure may be defined as any condition that leads to replacement. These conditions include secondary caries, irreversible pulpitis, excessive wear of opposing tooth surfaces, excessive erosion and roughening of the ceramic surface, ditching of the cement margin, unacceptable esthetics, cracking, chipping and fracture. A systematic review of the dental literature was performed to determine the extent to which the mechanical and physical properties of dental alloys and ceramics can predict the 5-year clinical performance of metal-ceramic and all-ceramic fixed dental prostheses (FDP) and to determine the associated quality of reported outcomes associated with these clinical studies.
MATERIALS AND METHODS
The review was based on clinical research studies of 5 years or greater duration that were published in English dental journals between 1980 and 2006 using the following key words and MeSH terms. Our search strategy was as follows: Search 1: Partial fixed denture OR denture, partial, fixed OR denture, partial fixed OR dental porcelain OR metal ceramic alloys OR dental ceramic Search 2: Prosthesis failure OR dental restoration failure OR time factors OR survival analysis Search 3: Meta-analysis OR evaluation studies OR review OR clinical trial OR comparative study OR follow-up studies OR prospective studies OR clinical follow-up study OR clinical trial OR longitudinal studies Inclusion of searches 1, 2 and 3 and limits placed on the publication date starting on January 1, 1980, English language, and clinical studies involving humans resulted in a total of 684 articles. By restricting the clinical studies to 5 years or more in duration, the number was reduced to 193. By eliminating resin-bonded FDPs, cantilever designs, implant-supported prostheses, crowns, inlay- or onlay-supported prostheses, a total of 37 articles remained for detailed review. After excluding review articles and articles involving resin-bonded bridges, single-author clinical research articles, cantilever designs and implant-supported FDPs, 11 clinical research articles remained. For these articles, it was not possible to determine conclusively the probability of failure for three-unit FDPs compared with four-unit and larger prostheses or the location of the crowns and pontics.
RESULTS
This systematic review of studies on ceramic-based FDPs confirms the results of previous studies that, in most cases, less than 15% of these prostheses were removed or were in need of replacement at 10 years. However, there was considerable variability in the number of parameters that were reported as well as the range of details on failures that occurred. In some studies, a standardized evaluation system was used in which USPHS or Ryge criteria were applied. However, there was also great uncertainty in the definition of failure with respect to repairable fractures and whether the identified causative factors were directly or indirectly associated with the replacement of the prostheses.
CONCLUSIONS
This review indicates that there is no single in vitro test variable that can predict clinical performance in these prostheses. Based on these reviews, there is an urgent need to develop a comprehensive classification system for identifying clinical prosthesis failures, technical complications and biologic complications. Guidelines on the retrieval of fractured prostheses and/or impressions that capture the fracture surface details should also be developed. The predictive power of in vitro data can be increased by finite element stress analysis and computer programs such as the CARES/Life software (NASA Lewis Research Center, Cleveland, OH) that estimates the time-dependent nature of ceramic structure survival.

Review
AIM
Aim of the study was to evaluate the long-term reliability and effectiveness of inlays and onlays in ceramic and composite material, examining scientific studies published from 2004 to 2013. The results of this review were analyzed and compared with the important literature review proposed by Manhart in 2004.
METHODS
With this review it was possible to analyze a total sample of 5858 Class I and II restorations, made in the posterior region: 5295 ceramic and 563 composite restorations in 2377 patients. Works were evaluated using USPHS, modified USPHS and CDA criteria after a mean observation period of 5.4 years (5.9 years for ceramic restorations, 2.6 for composite restorations).
RESULTS
The arithmetic average of success was 94%, higher in ceramic restorations (94.9%) than composite materials (91.1%). The weighted average success rate was 95.3%, 92.8% for composite restorations and 96.3% for ceramic ones. The highest rates of success were found in ceramic restorations notwithstanding the longer observation period.
CONCLUSION
Indirect restorations have a low failure rate and they prove to be an excellent choice in the treatment of both class I and II lesions. During the last 6 years, the parameters related to these restorations have improved, with a 4% increase of success.

The Cochrane Database of Systematic... 2000Foot ulceration is thought to affect 15% of all people with diabetes at some time during their life. (Review)
Review
BACKGROUND
Foot ulceration is thought to affect 15% of all people with diabetes at some time during their life.
OBJECTIVES
To assess the effectiveness of pressure relieving interventions in the prevention and treatment of diabetic foot ulcers.
SEARCH STRATEGY
Searches of 19 databases, hand searching of journals, bibliographies and identification of unpublished work by written communication with recognised experts in the diabetic foot.
SELECTION CRITERIA
Randomised controlled trials evaluating pressure relieving interventions either in the prevention or the treatment of diabetic foot ulcers. There was no restriction on articles/trials based on language or publication status.
DATA COLLECTION AND ANALYSIS
Data extraction and assessment of study quality was undertaken by two reviewers independently. Each trial was analysed separately, no pooling of results was possible due to the difference in patients, comparisons and outcomes.
MAIN RESULTS
Prevention 4 RCTs of pressure relieving interventions were identified. Interventions for the prevention of diabetic foot ulcers indicated that in-shoe orthotics are of benefit. The relative merits of different in-shoe orthotics are unclear; cushioning and pressure redistribution appear of equal benefit. Other pressure relieving interventions such as running shoes have not been adequately evaluated and removable casts (Scotchcast or Hope) or foam inlays do not appear to have been evaluated at all in randomised controlled studies. Treatment 1 RCT of total contact casting indicated that it was effective in the treatment of diabetic ulcers although the evidence was limited.
REVIEWER'S CONCLUSIONS
Prevention There is limited evidence of the effectiveness of orthotic interventions over removal of callus. There is some evidence evaluating the relative effectiveness of two types orthotic devices. There is very limited evidence of the effectiveness of therapeutic shoes. Treatment There is very limited evidence of the effectiveness of total contact casts in the treatment of diabetic foot ulcers. Overall there is a need to measure the effectiveness of the range of pressure relieving interventions for the prevention and treatment of diabetic foot ulcers as there is a small amount of poor quality research in this area.

Review
OBJECTIVE
This systematic review of clinical trials seeks to identify the clinical performance of intra-coronal CEREC restorations luted with an adhesive composite technique. The focus of the review is to establish the survival rate of these restorations and to identify the factors that may cause them to fail.
METHOD
A comprehensive literature search was undertaken, spanning from the year of introduction of the technology--1986 to 1997. This review identifies universal indicators of the clinical performance of intra-coronal CEREC restorations luted with an adhesive composite technique. Throughout the critical appraisal, each individual study was analysed identifying the aims, the methodology and materials used and the results obtained.
RESULTS
29 clinical reports were identified in the search. The systematic analysis reduced the focus of review to 15 studies. The data available establishes ceramic intra-coronal restorations machined by the CEREC system as a clinically successful restorative method with a mean survival rate of 97.4% over a period of 4.2 years. The review also highlights the reasons and the rates of failure for this type of restoration. The predominant reasons for failures are fracture of the ceramic, fracture of the supporting tooth, postoperative hypersensitivity and wear of the interface lute.
SIGNIFICANCE
Machinable ceramics, as used by the CEREC system provide a useful restoration with a high success rate. These restorations are color stable and wear at a clinically acceptable rate. Wear of the luting composite on occlusal surfaces leads to the phenomenon of submargination. Ceramic fracture, wear at the interface and post-operative hypersensitivity remain a problem which require further investigation.

Meta-Analysis
OBJECTIVES
To evaluate the survival rate of ceramic and indirect composite inlays, onlays, and overlays manufactured according to different methods (CAD/CAM, pressable, and stratified). MEDLINE, EMBASE, and Cochrane Library databases were searched for published articles. Risk of bias, data extraction, subgroup analysis, meta-analysis, and GRADE was performed.
MATERIALS AND METHODS
Prospective, retrospective, or RCT studies, without restriction of language, from 1983 to 2019, with follow-up ≥5 years, reporting survival rates were screened independently by two reviewers in accordance with eligibility criteria.
RESULTS
A total of 13 articles (12 for ceramic, one for indirect composite) met the inclusion criteria. No articles were included regarding crystalline ceramic. The estimated cumulative survival rate for CAD/CAM was 97% after 5 years and 89% after 10 years; for pressable was 95% after 5 years, and for stratified was 88% after 5 years and 93% after 10 years.
CONCLUSIONS
Regardless of the manufacturing method, vitreous ceramic inlays, onlays, and overlays showed high survival, providing evidence that these restorations are a safe treatment.
CLINICAL RELEVANCE
Vitreous ceramic inlays, onlays, and overlays showed high survival, regardless of the manufacturing method, providing evidence that these restorations are a safe treatment.

Meta-Analysis
OBJECTIVES
This systematic review aimed to collect and interpret the randomized clinical trials (RCTs) that investigated the outcome of the self-adhesive luting resins (SA) compared to total-etch (TE), selective etch with dentin adhesives (Sle), selective etch without dentin adhesives (SleSA) or self-etch adhesives (SE).
DATA SOURCES
A thorough search of Internet databases was conducted without language restrictions, and the search ran up to and including April 2022. The illegible records citations were checked for more relevant clinical studies.
STUDY SELECTION/RESULTS
The inclusion criteria were randomized controlled trials (RCTs) that compared self-adhesive luting resins with total-etch, selective-etch, or self-etch adhesives regarding postoperative sensitivity, incidences of debonding, and survival rates of indirect restorations. From 1732 records, 9 RCTs met the eligibility criteria. Three RCTs compared total-etch adhesive to self-adhesive luting resin for intracoronal restorations, one RCT compared selective etch to self-adhesive luting resin for inlays, and 5 RCTs compared self-adhesive to other protocols for partial ceramic crowns. Postoperative sensitivity showed a non-statistically significant difference between SA and other adhesive protocols, SA revealed a non-statistically significant difference in debonding and survival to TE, but a lower statistically significant difference to Sle, SleSA, and SE.
CONCLUSIONS
Postoperative sensitivity might not be affected by the adhesive protocol. In relatively short observation, TE revealed comparable survival to SA for intracoronal restorations. SE and Sle exhibited the best clinical outcomes, followed by SleSA. Selective etch, and self-etch adhesives are preferable to self-adhesive resins.
CLINICAL SIGNIFICANCE
The significance of enamel etching and the superiority of self-etching adhesives over self-adhesive luting resins for reliable and durable bonding and improved clinical outcomes. However, long-term RCTs, particularly for total-etch comparison to self-adhesive luting resins, might be recommended to derive further evidence.
