[Long-term results of front teeth restoration using light-curing composite materials]

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Light-curing composite restorations are widely used for anterior teeth.
• Long-term clinical and aesthetic performance data for various composite types are crucial for clinical decision-making.

Purpose of the Study:

• To evaluate the long-term clinical and aesthetic outcomes of different light-curing composite materials used in anterior tooth restorations.
• To identify factors influencing the longevity and success rates of these restorations.

Main Methods:

• Clinical examination of 500 anterior tooth restorations (microfills, hybrids, compomers, combined) placed 5-9 years prior.
• Evaluation of clinical and aesthetic parameters.
• Assessment of restoration replacement rates and 'excellent' ratings.

Main Results:

• Overall, 19.2% of restorations required replacement, with only 10% rated as 'excellent'.
• Direct veneers made from microfilled composite materials demonstrated the highest success rate, with 30% achieving 'excellent' status.
• Restorations on devital teeth and V-class restorations using compomer materials showed poorer outcomes, with 20% requiring replacement.

Conclusions:

• Microfilled composite direct veneers offer superior long-term aesthetic and clinical performance for anterior restorations.
• Compomer materials may be less suitable for challenging restorations such as those on devital or V-class teeth.
• Material selection and tooth type significantly impact the longevity of composite restorations.
