Ask ChatGPT about the research

Etching by phosphoric acid is considered an important factor to achieve resin bonding to Primary enamel. Bond strength was significantly higher in the third group (etching for 35sec) than the other groups (etching for (15), (25), or (45)sec). There were no significant differences in bond strength between etch durations: (15), (25), or (45) sec.

The etching primary teeth dentin is more important factors for bonding composit with primary teeth dentin. objective: The aim of this research is to know the effect of time etching with the phosphoric acid 37% by duration (7 or 15 seconds) for the composite bonding strength with primary molar dentin towards shear strength.
The purpose of this study was to evaluate the effect of preetching with phosphoric acid on microleakage of self-etch adhesive material Adhes E in primary teeth. The study involve 50 primary teeth(molars ,canins )which extracted for orthodontic re asons had no caries ,fractures ,crack. The teeth were gathered in Hama university-pediatric dentistry department. Class v cavity prepared in all samples.
This study aimed to compare the effects of different enamel etching techniques for bracket bonding strength. The sample consisted of eighty human premolars were randomly divided into four equal groups. The enamel surfaces of the teeth were etched with 35% orthophosphoric acid in Group 1 , air abraded with 50 μm aluminum oxide prior to acid etching in Group 2, Trans bond Plus Self-etching Primer (TPSEP) in Group 3 , Er: YAG laser in Group 4. After enamel etching procedures, brackets were bonded with Trans bond XT , then shear bonding test was performed using a testing machine (Tinius Olsen).
Debonding of acrylic denture teeth from denture base is the most common failure in removable dentures . The purpose of this study was to evaluate shear bond strength between acrylic denture teeth and heat cure denture base resin with different surface treatment and modifications on the ridge lap area By Using Conventional Method and Blasting Method.
Laser use and applications in dentistry has increased dramatically in the last years. Laser etching of enamel may provide an alternative for conventional acid etching. The aim of this study was to evaluate, under Scanning Electron Microscope(SEM), enamel surface morphology after laser irradiation with or without the addition of photoabsorber (black ink); with or without acid etching. laser enamel etching produced surface roughness that might be used for the infiltration and subsequent mechanical retention of resin.
