Filter by:In restorative dentistry, to enhance bond strength between dentin and simplified adhesive systems, new materials or applications are constantly being developed all the time. In order to create a better hybrid layer quality, modifications are made to the chemical contents and application methods of the adhesives. For inhibition or slow down of collagen or resin matrix degradation at the adhesive interface, procedures like using protease enzyme inhibitors or additional hydrophobic layer applications are tested by in vitro and in vivo studies. The main goal of this double-blind randomized clinical trial is to evaluate the 18-month clinical performances of two different one-step dentin adhesives that were applied alone or with an additional hydrophobic adhesive layer to non-carious cervical lesions. The hypotheses are that (1) Additional Hydrophobic Adhesive layer application can provide better clinical performance in class V restorations and, (2) the HEMA content will cause statistically different clinical performances.
The goal of this clinical study is to compare the clinical performance of a new 2-steps universal adhesive in patients with non-carious cervical lesions. The main question it aims to answer is: Is there any difference in clinical performance of a new 2-steps universal adhesives bonded with different etching strategies. Participants will have restorations using a new 2-steps universal adhesives in different etching strategies. - etch-and-rinse - selective enamel etching - self-etch
The aim of this randomized, prospective, parallel, double-blind clinical trial will be to evaluate the clinical performance of restorations performed in non-carious cervical lesions (NCCL) using a soft ph universal adhesive system, varying the adhesive strategy (self-etching vs. selective etching of the enamel) and the sclerosis characteristics of the dentinal substrate over 24 months.
The study aims at determining the prevalence of non carious cervical lesions in patients with gingival recession in Egyptian population and associated risk factors including gingival biotype, keratinized tissue width, gingival index, plaque index, occlusal wear grade, sensitivity. and a questionnaire will be filled by patients with another risk factors including age, gender, toothbrush frequency and type, bruxism, gastric reflux, soft drinks, alcohol and citrus fruits. Also OHIP-14 will be answered in a questionnaire form by patients.
The objective of this randomized, double-blind clinical trial is to evaluate the clinical performance of non-carious cervicals adhesive restorations using three self-etching adhesives containing HEMA and 10-MDP monomers.
This study will be conducted to evaluate the clinical performance of self-cured adhesive versus light cured universal adhesive in non-carious cervical lesions (NCCL) resin composite restorations after 18 month
Composite restoration of non-carious cervical lesions has always been a challenge for the clinician, considering that the most frequent cause of failure is retention loss. Adhesion of composite restoration may be obtained by following four different etching techniques: total-etch in three steps, total-etch in two steps, self-etch in two steps, and self-etch in one step. Nowadays the tendency is to simplify the adhesive classic protocols. With the introduction of universal adhesives such as Prime&Bond Active (Dentsply Sirona) it is possible to obtain a total-etch pattern (enamel and dentine) without the classic etching technique with orthophosphoric acid. On the other hand, there has been an increase in the awareness of the importance of remaining dental tissue preservation, avoiding preparation of a cavity. This is why it is now preferable to use bioactive glass in order to increase micromechanical retention on the dental surface, instead of the classical approach of preparing the surface with burs. To date, there are no studies evaluating the clinical performance of the universal adhesive Prime&Bond Active on direct resin composite restoration of non-carious cervical lesions neither in a selective-etch mode (enamel etching) or a self-etch mode (no etching) or using sandblasting with bioactive glass. Therefore, the main objective of the study is to evaluate the retention rate of composite restorations using Prime&Bond Active and a previous sandblasted surface with bioglass in a three-year follow-up, as well as the presence of marginal discoloration, marginal integrity and marginal caries.
