The Proximal Contact Tightness and Location in Class II Composite Restorations

Clinical Evaluation of the Proximal Contact Tightness and Location in Class II Composite Restoration Using Different Contact Forming Instruments

This study aims to investigate consecutive biological changes in proximal contact tightness using digital force gauge and evaluate proximal contact location using cone beam computed tomography between class II direct composite restorations and adjacent teeth after using sectional matrix system and with different contact forming instruments.

Inclusion Criteria:

• Presence of proximal caries in CBCT x-ray with score 3 to 4 according to the radiographic International Caries Detection and Assessment System (ICDAS).
• Presence of the antagonist and the adjacent tooth making contact.
• The teeth to be restored had to show no signs of pulpitis but positive sensitivity using endo ice testing.
• Size of the isthmus with no more than 2/3 of the intercuspal distance
• Good oral health and absence of periodontal disease
• Patients who are not suffering from severe systemic diseases or allergies

Exclusion Criteria:

• Medically compromised patients
• Clinical signs of bruxism, traumatic malocclusion
• Pregnant or breast feeding at the time of restoration placement
• Intolerance or allergy toward the applied restorative materials
