One Year Clinical Evaluation of Two Different Types of Composite Resins in Posterior Teeth

Abstract

Aim: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. Methods and Materials: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. Results: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 rates for Z-250 were 100% and 97.1% Alpha at six and 12 months, respectively. Statistical analysis was completed with Fisher's exact and McNemar Chi-square tests at a significance level of 5% (P<0.05). Conclusion:All restorations were clinically satisfactory and no significant differences were found among them.

Survival of direct resin restorations in posterior teeth within a 19-year period (1996–2015): A meta-analysis of prospective studies

“…The selection of the study population in terms of good compliance [22][23][24][25][26][27][28] has already been described elsewhere [29][30][31]. Another way of patient selection in order to reduce the caries risk among the participants is to exclude patients who are not following a certain level of oral hygiene [26,[32][33][34][35][36][37][38][39][40][41][42][43]. There are only a few studies where the exclusion of patients encompassing high caries risk, periodontal disease or parafunctional habits was not applied, e.g.…”

“…This is in accordance with findings in other studies. 2,4,11,[22][23][24] According to Van Dijken, 3 most of the wear of composite restorations occurs during the first 6 to 12 months and diminishes during the following years.…”

Three-year Clinical Evaluation of Different Restorative Resins in Class I Restorations
