A 5-year report on a enamel-dentinal bonding agent and microfilled resin system

Area of Science:

• Dental Materials Science
• Restorative Dentistry

Background:

• Dental composite restorations are widely used for esthetic and functional tooth repair.
• Long-term clinical performance data for specific bonding systems and composite resins are essential for evidence-based practice.

Purpose of the Study:

• To assess the 5-year clinical performance of the Gluma enamel dentinal bonding system combined with Pekalux microfilled composite resin.
• To evaluate marginal integrity, color stability, and anatomic form of the restorations.

Main Methods:

• Sixty esthetic restorations were placed by three operators.
• Forty restorations were evaluated after 5 years using Alpha and Bravo scoring systems.
• Restorations were assessed for marginal integrity, color stability, and anatomic form.

Main Results:

• A significant number of restorations received Alpha scores for marginal integrity, color stability, and anatomic form.
• Bravo scores indicated areas for improvement in these parameters for some restorations.
• Six restorations required replacement over the 5-year period.

Conclusions:

• The Gluma bonding system and Pekalux composite resin demonstrated moderate clinical performance over 5 years.
• Periodic maintenance, including conservative polishing and oral hygiene sessions, is vital for optimizing restoration longevity.
• Regular patient follow-up is recommended to ensure the long-term success of dental restorations.
