ObjectivesThe dental field is gradually reducing the use of amalgam and moving towards adhesive restoration. This change is in accordance with the advancement and improvement of composite resin materials and adhesion systems. Consequently, posterior cavity preparations teaching should be re‐examined to determine whether dental schools are adapting their curriculum to fit the current trends in dentistry and what rationale supports their decisions.MethodsAn online questionnaire was constructed to assess the time dedicated to teaching composite materials and amalgam, in addition to the principles of posterior preparations, for composite restorations in North American dental schools.ResultsA total 33 schools responded to the questionnaire. A large variation was found in teaching methods and techniques of posterior restorations. The reasoning for teaching amalgam restorations was diverse as were the principles of composite resin preparation taught.ConclusionNo agreed principles of cavity...
Clinical performance of resin composite restorations placed by dental students
Brazilian Journal of Oral Sciences, 2022
Aim: A retrospective, cross-sectional study was carried out to evaluate the performance of resin composite restorations placed by undergraduate dental students with 1 to 15 years of placement based on dental records. Methods: Four calibrated operators evaluated 498 restorations (anterior and posterior) of 120 patients according to Ryge’s validated criteria (USPHS). Results: The criteria that showed the smallest changes between the types of failures were color matching, marginal discoloration and surface texture. Regarding the longevity, the surface texture showed an increase in the frequency of failures from the second time interval (3.1 to 6 years). Higher prevalence of failure was found in class II and III restorations, with secondary caries being the main reason. No significant differences were found for anatomic form, marginal adaptation, and color matching. Class V restorations showed a higher fracture rate with total displacement of the restoration, with no increase in the fre...
One year clinical evaluation of two different types of composite resins in posterior teeth
The journal of contemporary dental practice, 2008
The aim of this study was to assess the clinical performance of two adhesive restorative systems (Single Bond/Filtek P-60 and Single Bond/Filtek Z-250) in posterior teeth using a modified United States Public Health Service (USPHS) system. A total of 70 restorations were placed in molars and premolars in 30 patients (14 females and 16 males; 18-40 years) by one operator. All restorations were directly evaluated by two examiners at baseline, six months, and 12 months using the following modified USPHS rating criteria: marginal integrity, marginal discoloration, surface texture, contour, postoperative sensitivity, and recurrent caries. At six and 12 months all restorations were available for evaluation of marginal discoloration, surface texture, contour, postoperative sensitivity, and recurrent caries that remained with 100% Alpha-ratings at recalls for both restorative systems. Marginal integrity for P-60 was scored as 94.3% and 91.4% Alpha at six and 12 months, respectively, and rat...

Composites are increasing in popularity as restorative materials. This growing role indicates the necessity of studies on their clinical outcome. Clinical studies published on the performance of posterior composite restorations were included except those of less than a 24-month assessment period. Results of non-vital, anterior or primary teeth and cervical-single-surface restorations were also excluded. Records about composite type, number of final recall restorations, failure/survival rate, and assessment period and failure reasons were analyzed for each decade. Overall survival/failure rates for studies in 1995-2005 were 89.41%/10.59% and for 2006-2016 were 86.87%/13.13% respectively. In 1995-2005 the reasons for failure were secondary caries (29.47%) and composite-fracture (28.84%) with low tooth-fracture (3.45%) compared to reasons of failure in 2006-2016, which were secondary caries (25.68%), composite-fracture (39.07%), and tooth-fracture (23.76%). An increase in incidence of ...
The teaching of posterior composites: A survey of dental schools in Oceania
Journal of Dentistry, 2019
To investigate current teaching and operative techniques of posterior composite restorations in dental schools in Oceania (Australia, New Zealand, Fiji and Papua New Guinea). Methods: A 24-item validated questionnaire including closed and open questions was mailed to the Heads of Department of Operative/Restorative Dentistry in 16 dental schools. Responses were compiled in Excel and analyzed. Results: The response rate of this study was of 94% (n = 15). All respondent schools taught the use of posterior composites for occlusal and occluso-proximal cavities in premolars and molars. The mean percentage of preclinical teaching devoted to composites was greater than for amalgam (39% vs 29%). This proportion was anticipated to be 3:1 for posterior composite/amalgam in five years' time. Most posterior restorations placed by students are composites (average 64%, ranging from 10 to 100%), with amalgam representing 19.5% of the restorations placed (ranging from 0%-50%). Slot-type cavities were the preparation techniques most commonly taught (80%) and most schools (67%) teach the mandatory use of rubber dam for moisture control. The most common contraindication to composite placement (67% of the schools) was a history of adverse reaction to composites. The phase down of teaching and use of amalgam in Oceania is expected to occur within 8-10 years. Conclusions: Despite minimally invasive approaches becoming increasingly common worldwide, the use of amalgam is still taught in Oceania. Future studies should assess whether the clinical teaching of posterior composites is in keeping with material development and trends in mainstream dental practice.
Contemporary teaching of direct posterior composite restorations in Saudi dental schools
The Saudi Journal for Dental Research, 2017
The teaching of posterior composites has undergone considerable assessment and refinement in well-developed countries in recent years. However, little information exists on this teaching in Arab countries. Aim of this study: The aim of this study was to investigate the teaching of direct posterior composite restorations to undergraduate dental students in Kingdom of Saudi Arabia (KSA). Method: An online survey was developed and distributed to 17 Saudi dental schools. The topic of the survey sought information related to current teaching of direct posterior composite restorations in undergraduate teaching programs. Results: Responses were received from 13 schools (response rate = approximately 76%). All respondent dental schools taught the same types of restorations, however there were some variations regarding contraindications of such restorations. In certain dental schools, outdated knowledge was taught related to cavity specifications such as beveling of occlusal margins, the use of clear plastic matrix band and light reflecting wedges. There was shortening of knowledge related to light curing technologies as well as different adhesive systems. Nano-filled dental composite was not taught in approximately half of the respondent schools. Also, the rush into teaching of bulk-fill placement technique was noted. Conclusions: Among Saudi dental schools, there may be some degree of variation in the teaching of posterior composite restorations. Although, some teaching shortcomings were noted, the overall extent and content taught to dental students in KSA may provide enough knowledge that may be essential for preclinical and clinical practice of the direct posterior composite restorations.

Despite the widespread acceptance of conventional treatment using composite resin in primary teeth, there is limited evidence that this approach is the best option in paediatric clinics. Atraumatic restorative treatment (ART) using high-viscosity glass ionomer cement has gradually become more popular because it performs well in clinical studies, is easy to handle and is patient friendly. Therefore, the aim of this randomised clinical trial study is to compare the restoration longevity of conventional treatment using composite resin with that of ART in posterior primary teeth. As secondary outcomes, cost-efficacy and patient self-reported discomfort will also be tested. Children aged 3-6 years presenting with at least one occlusal and/or occlusal-proximal cavity will be randomly assigned to one of two groups according to the dental treatment: ART (experimental group) or composite resin restoration (control group). The dental treatment will be performed at a dental care trailer locate...

An increase in incidence of composite fracture, tooth fracture and need for endodontic treatment as failure reasons was noted in the latter decade in addition to a decrease in secondary caries, postoperative sensitivity, unsatisfactory marginal adaptation and wear. The overall rates of failure showed little difference, but the causes showed a notable change. This is believed to be a reflection of increased use of composites for larger restorations and possibly changes of material characteristics.
