About

clinical evaluation of the effect of preheating BIS-GMA free resin composite at different temperatures on temperature change of the pulpal floor and restorations and compare it with BIS-GMA containing resin composite.

Hypothesis: Could the preheated composite affect the temperature of the pulpal floor

Enrollment: 20 patients

Sex: All

Ages: 25 to 45 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Immature teeth.
• Radiographic evidence of external or internal root resorption.
• Alcoholic and smoker patients.

• Patients who had non-carious lesions like attrition, erosion, abrasion or abfraction.
• Patients had participated in a clinical trial within 6 months before commencement of this trial.
