Comparison Between Two Types Of Matrix Systems For Contact Tightness In Class-Ii Composite Restorations

Area of Science:

• Restorative Dentistry
• Dental Materials Science

Background:

• Achieving tight proximal contacts in Class II composite restorations is challenging.
• Circumferential and sectional matrix bands are commonly used for proximal restorations.

Purpose of the Study:

• To compare the contact tightness achieved with sectional (Palodent Plus) and circumferential (Tofflemire) matrix band systems.
• To evaluate the effectiveness of different matrix systems in composite restorations.

Main Methods:

• A quasi-experimental study involving 30 patients (60 cavities).
• Both Tofflemire and Palodent Plus systems were used in each patient for Class II composite restorations.
• Contact tightness was assessed using Fédération Dentaire Internationale criteria.

Main Results:

• The Palodent Plus system demonstrated superior contact tightness compared to the Tofflemire system.
• Statistically significant differences (p=.037) were found in contact tightness between the two systems.
• Palodent Plus achieved higher scores for tight contacts (55% score 1, 28.3% score 2) versus Tofflemire (46.7% score 4, 31.7% score 5).

Conclusions:

• Sectional matrix band systems are statistically superior to circumferential systems for achieving tight contacts in Class II composite restorations.
• The Palodent Plus system offers better outcomes for proximal contact tightness.
