The following resources related to this article are available online at Background. The authors conducted a two-year clinical trial to evaluate the effectiveness of two resin-based composite materials for Class II restorations placed according to two filling techniques. Methods. Twenty-six patients received 105 Class II restorations, which the authors distributed randomly into three groups of 35 each. The resin-based composite restorations in group A were composed of average-density material (Ceram X mono [CXM], Dentsply DeTrey, Konstanz, Germany) placed according to the oblique incremental technique (OIT). Restorations in group B were composed of average-and highdensity materials (CXM and SureFil [SF], Dentsply DeTrey) placed according to the modified incremental technique (MIT). Restorations in group C were composed of the high-density material (SF) placed with the OIT. The authors evaluated the restorations according to modified U.S. Public Health Service criteria.

Clinical Outcomes of Bulk-Fill versus Layered Resin Composite Restorations
Objectives: This study was conducted to evaluate and compare the clinical performance of class II restored with Tetric EvoCeram bulk-fill, Filtek bulk-fill resin composite, and layered Filtek Z250 resin composite restorations. Materials and Methods: Thirty class II cavities were prepared. The cavities were randomly divided into three groups (n=10) according to the restorative material used (Tetric Evoceram Bulk fill, Filtek bulk-fill and Filtek Z250). The patients were recalled at 6 months and restorations were evaluated using Modified United State Public Health Criteria (USPHS). Results: No statistically significant difference between all the tested restorative materials. Conclusions: Bulk fill restorative materials (Tetric Evoceram bulk fill & Filtek bulk-fill) showed clinical outcomes like that of conventional resin based composite.
A 3-year retrospective study of clinical durability of bulk-filled resin composite restorations
Restorative Dentistry & Endodontics, 2022
Objectives: This study aimed to assess the clinical longevity of a bulk-fill resin composite in Class II restorations for 3-year. Materials and Methods: Patient record files acquired from the 40 patients who were treated due to needed 2 similar sizes Class II composite restorations were used for this retrospective study. In the experimental cavity, the flowable resin composite SDR was inserted in the dentinal part as a 4 mm intermediate layer. A 2 mm coverage layer with a nano-hybrid resin composite (CeramX) was placed on SDR. The control restoration was performed by an incremental technique of 2 mm using the nano-hybrid resin composite. The restorations were blindly assessed by 2 calibrated examiners using modified United States Public Health Service criteria at baseline and 1, 2, and 3 years. The data were analyzed using non-parametric tests (p = 0.05). Results: Eighty Class II restorations were evaluated. After 3-years, 4 restorations (5%) failed, 1 SDR + CeramX, and 3 CeramX restorations. The annual failure rate (AFR) of the restorations was 1.7%. The SDR + CeramX group revealed an AFR of 0.8%, and the CeramX group an AFR of 2.5% (p > 0.05). Regarding anatomical form and marginal adaptation, significant alterations were observed in the CeramX group after 3-years (p < 0.05). The changes in the color match were observed in each group over time (p < 0.05). Conclusions: The use of SDR demonstrated good clinical durability in deep Class II resin composite restorations.
The aim of the study was to assess the clinical performance of class II composite resins restorations performed using different restorative techniques. Materials and methods The study group included 37 patients aged between 18-42 years. A number of 60 class II direct restorations were performed by a single practitioner using adhesive preparation design with margin bevelling and hybrid composite resin Herculite XRV (Kerr) as restorative material. The teeth included in the study were divided in three groups (n=20) accordingly to restorative technique: I. centripetal build-up; II. oblique layering technique; III. horizontal layering technique. The class II composite resins restorations were assessed after 12 months using United States Public Health Services (USPHS) criteria. Results and discussions The centripetal build-up technique presented the score A for marginal adaptation in 60%, for marginal discoloration in 70% and for anatomical form in 80% of the restorations. The horizontal layering technique presents the score A for marginal adaptation in 40%, for marginal discoloration in 50% and for anatomical form in 50% of the restorations. The oblique layering technique presented the score A for marginal adaptation in 80%, for marginal discoloration in 90% and for anatomical form in 60% of the restorations. Conclusions Statistical differences between groups were found regarding marginal adaptation (oblique layering technique versus horizontal layering technique), marginal discoloration (oblique layering technique versus horizontal layering technique) and anatomical form (centripetal build-up technique versus horizontal layering technique).
56-month clinical performance of Class I and II resin composite restorations
Journal of applied oral science : revista FOB
This study evaluated the 56-month clinical performance of Class I and II resin composite restorations. Filtek P60 was compared with Filtek Z250, which are both indicated for posterior restorations but differ in terms of handling characteristics. The null hypothesis tested was that there is no difference in the clinical performance of the two resin composites in posterior teeth. Thirty-three patients were treated by the same operator, who prepared 48 Class I and 42 Class II cavities, which were restored with Single Bond/Filtek Z250 or Single Bond/Filtek P60 restorative systems. Restorations were evaluated by two independent examiners at baseline and after 56 months, using the modified USPHS criteria. Data were analyzed statistically using Chi-square and Fisher's Exact tests (a=0.05). After 56 months, 25 patients (31 Class I and 36 Class II) were analyzed. A 3% failure rate occurred due to secondary caries and excessive loss of anatomic form for P60. For both restorative systems, ...
Direct resin composite restorations versus indirect composite inlays: one-year results
The journal of contemporary dental practice, 2010
The aim of this study was to evaluate the clinical performance of direct resin composite restorations (Tetric Ceram-TC) and indirect composite inlays (Targis-TG) after 12 months. Seventy-six Class I and II restorations (44 direct and 32 indirect) were inserted in premolars and molars with carious lesions or deficient restorations in 30 healthy patients according to the manufacturer's instructions. Each restoration was evaluated at baseline and after 12 months according to the modified USPHS criteria for color match (CM), marginal discoloration (MD), secondary caries (SC), anatomic form (AF), surface texture (ST), marginal integrity (MI), and pulp sensitivity (PS). Data were analyzed by Fisher and McNemar Chi-square tests. No secondary caries and no pulpal sensitivity were observed after 12 months. However, significant changes in marginal discoloration (MD) criteria could be detected between baseline and one-year results for both materials (p<0.05). For marginal integrity (MI)...
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...

This randomized study evaluated a flowable resin composite bulk-fill technique in posterior restorations and compared it intraindividually with a conventional 2-mm resin composite layering technique over a 6-yr follow-up period. Thirty-eight pairs of Class II restorations and 15 pairs of Class I restorations were placed in 38 adults. In all cavities a single-step self-etch adhesive (Xeno V) was applied. In the first cavity of each pair, the flowable resin composite (SDR) was placed, in bulk increments of up to 4 mm. The occlusal part was completed with a layer of nanohybrid resin composite (Ceram X mono). In the second cavity of each pair, the hybrid resin composite was placed in 2-mm increments. The restorations were evaluated using slightly modified US Public Health Service (USPHS) criteria at baseline and then annually for a time period of 6 yr. After 6 yr, 72 Class II restorations and 26 Class I restorations could be evaluated. Six failed Class II molar restorations, three in each group, were observed, resulting in a success rate of 93.9% for all restorations and an annual failure rate (AFR) of 1.0% for both groups. The AFR for Class II and Class I restorations in both groups was 1.4% and 0%, respectively. The main reason for failure was resin composite fracture.
