Abstract
The article describes in vitro evaluation of the micro-shear bond strength between composite resin and dentin specimens treated with self-etching, total-etching and universal dental adhesives for patients of different ages. The authors compared microstructure of resin-infiltrated zone for self-etching, total-etching and universal dental adhesive systems by means of scanning electron microscopy. These findings presented negatively effects of aging on the bond strength of dentinal surfaces and the advantages of adhesive protocol with universal adhesives for all ages.
Highlights
The proportion of older people continues to grow worldwide, especially in developing countries
Periodontal attachment loss occurs in association with aging, usually manifests as periodontitis or recession on the buccal surface of teeth, occurs in 89% of the population over 65 years old, but the peak incidence is observed at 3540 years [4, 5]
Composite resin material was manually applied in 3 mm plastic post on the surface of dentin and light-cured by a visible-light-curing unit for 30 seconds
Summary
The proportion of older people continues to grow worldwide, especially in developing countries. Oral mucosa changes with aging include reduced wound-healing capacity [6]. Environmental factors, such as smoking, vaping, occupational hazards dramatically increase the risk of mucosal pathology [2, 3]. Both medication use and chronic diseases are more common in older adults [4, 5]. Healthy oral aging is important to whole process of healthy aging from both biological and social perspectives [2, 4, 5, 6]
