Clinical Comparison of Restorative Materials

This study was a double-blind (evaluator and patient) randomized controlled clinical study with three study groups with an equal allocation. Three different restorative materials were compared in deep cavities.

The treated patients were called back for controls after one week, six months, and twelve months. Restorations were evaluated clinically according to modified FDI criteria (marginal discoloration, color match, anatomical form, fracture and retention, marginal adaptation, contact point, post-operative sensitivity, secondary caries and periodontal response).

Clinical evaluation was performed by one qualified clinicians using a mirror and probe under reflector light. Bite-wing radiographs were taken from the patients who were called for controls at 6-moth and 12-month to evaluate the formation of secondary caries.

Differences between adhesives at each time period were evaluated using Fisher's Exact test. The effect of time on restorations was evaluated using Wilcoxon Signed rank test (p < 0.05).

Inclusion criteria

• Systemically healthy patients aged 18 and over
• Patients with good oral hygiene.
• Vital teeth are to be included in the study.
• The presence of an antagonist and a contact tooth for the tooth to be restored.
• Teeth with deep caries lesions or radiographically reaching ¾ of the dentin but with a hard dentin region between the caries and the pulp according to ESE (European Society of Endodontology) criteria.

Exclusion criteria

• Patients with a history of bruxism and periodontal disease
• Patients under 18 years of age
• Spontaneous pain in the tooth to be restored
• Intense carious lesion reaching the entire thickness of the dentin according to ESE (European Society of Endodontology) criteria
• Observation of mechanical perforation during caries cleaning
• Patients suspected of pregnancy or pregnant
