Author’s response I totally agree with comments by Pitak-Arnnop et al which emphasizes the importance of clinical relevance (though not statistically significant) and 95% CI confidence interval in today's publication process this change of mindset had evolved over many years of education on research & biostatistics. I must clarify that the present article is highlighting the well-known bias of ...

The relationship between wear resistance and filler size or filler loading was clarified for the universal resin composite; however, their relationship in flowable resin composites has not been clarified. The purpose of this study was to investigate the effect of filler size and filler loading on wear of experimental flowable resin composites by using a cyclic loading device. Nine experimental ...

To evaluate the effect of two types flowable composites and storage time on nano-leakage repaired water aged resin composite. In total, 30 composite discs were prepared stored in distilled for 6 m. The divided into groups (n=5/group) according to experimental factors: Factor 1: Flowable composite, 3 (no-flowable, high-viscosity low-viscosity composites), 2; Storage after repair, 2 (24 h m). Rep...

objective: probable effect of fluoride containing materials like apf on sealants is very important. the purpose of this study is to assess the effect of frequent application of apf (1.23%) on the surface microhardness of two fissure sealants and one flowable composite.   methods: in this experimental study, 81 specimens of two fissure sealants and one flowable composite were prepared, using spe...

BACKGROUND This study aimed to conduct a clinical evaluation of four restorative materials for restoration of dental wedge-shaped defect (WSD) and their impacts on periodontal tissues. MATERIAL AND METHODS A total of 280 maxillary premolars with dental WSD were selected from 106 patients; the patient cases were divided into eight groups according to different combinations of restorative materia...

INTRODUCTION The aim of this study was to evaluate and compare the in vitro effect of the Erbium-Doped Yttrium Aluminum Garnet (Er:YAG) laser with different radiation distances and high-speed rotary treatment on the shear bond strength of flowable composite to enamel of human permanent posterior teeth. METHODS freshly extracted human molar teeth with no caries or other surface defects were us...

Physical properties such as surface hardness of dental materials are directly linked to their clinical behavior. The aim of this study was to investigate the influence of extended curing time on the polymerization depth offluoride-containing materials used as pit and fissure sealants. Conventional and extended exposure times (20 and 60 seconds) were used to photoactivate a gold-standard pit and...

PURPOSE The purpose of this study was to evaluate and compare the effects of different surface pretreatment techniques on the surface roughness and shear bond strength of a new self-adhering flowable composite resin for use with lithium disilicate-reinforced CAD/CAM ceramic material. MATERIALS AND METHODS A total of one hundred thirty lithium disilicate CAD/CAM ceramic plates with dimensions ...

Improving the adaptation of resin composites during placement is necessary to increase durability and reduce microleakage. Flowable resin liners have been introduced to improve adaptation in composite restorations. In addition, a device that lowers the viscosity of regular dental composites has been introduced (Calset, AdDent Inc, Danbury, CT, USA). This device lowers the viscosity of composite...

Introduction: This study evaluated microleakage of flowable and conventional composite in primary molar class II restorations using self-etch and total-etch bonding agents. Methods: Class II standard cavities were prepared on proximal surface of 48 primary molars. These cavities were restored using GrandioFlow and Grandio composites and Futurabond DC and Solobo...
