Six-year Clinical Evaluation of Packable Composite Restorations

Abstract

A Kiremitci • T Alpaslan • S Gurgan Clinical RelevanceAs a posterior composite, Filtek P60 exhibited very good clinical performance in Class II cavities for six years. Methods: A total of 47 restorations were placed in the Class II cavity preparations (27 premolars and 20 molars) of 33 patients (22 female/11 male; mean age 34) by the same operator. The restorations were evaluated by two examiners at baseline and 1, 2, 3 and 6 years according to the method developed by Ryge, which also is known as the United States Public Health Service (USPHS) criteria. The following characteristics were observed: marginal adaptation, anatomical form, surface texture, marginal discoloration, surface staining, post-operative sensitivity and secondary caries. The Chi-square and Wilcoxon signed rank test with Bonferroni adjustment were used for statistical analysis (p=0.05).Results: All the restorations received Alpha scores at baseline assessment, except for one restoration, which showed post-operative sensitivity. At the three-year recall examination, two patients, with a total of three restorations, were not included. From baseline to three years, only two of the 44 restorations changed from Alpha to Conclusions: The clinical performance of the posterior composite restorations that were evaluated was acceptable after six years of service.

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

“…The superior behavior of P60 has been demonstrated in a study conducted by Kiremitci and others 19 In their clinical study, the clinical performance of P60 was acceptable after six years of service. Regarding marginal adaptation and discoloration, 95% and 91% of P60 restorations, respectively, received an Alpha rating.…”

The acid-base resistant zone in three dentin bonding systems

“…Good adhesion has been ascribed as the primary factor for enhancing the long-term sealing of the cavity margin, thereby protecting the restoration against secondary caries [1][2][3] . However, replacement of restorations due to secondary caries is still a prevalent problem in restorative dentistry.…”

Kekerasan mikro resin komposit packable dan bulkfill dengan kedalaman kavitas berbeda

“…Hal ini dapat mengakibatkan gigi sensitif pasca restorasi, karies sekunder, dan fraktur. 7 Bahan resin komposit dikembangkan terus terutama dalam hal  ller, matriks maupun inisiatornya. Akhir-akhir ini diperkenalkan tipe resin komposit baru yang dinamakan bulk ll.…”

“…Nilai kekerasan mikro untuk bahan resin komposit dapat menentukan derajad polimerisasinya, sehingga sangat berguna untuk mengetahui kekerasan mikro suatu bahan tersebut apabila bahan tersebut digunakan di klinik. 7 Hal ini disebabkan karena polimerisasi yang tidak adekuat dapat menghasilkan monomer sisa tinggi yang dapat mengiritasi jaringan pulpa, menstimulasi pertumbuhan bakteri, dan akhirnya berpengaruh terhadap kesuksesan restorasi di klinik. 5,13 Akhir-akhir ini penelitian mengenai resin komposit bulk ll banyak dilakukan, karena bahan ini termasuk bahan restorasi di bidang kedokteran gigi yang baru diperkenalkan beberapa tahun terakhir ini.…”
