Effect Of a Self-etch Adhesive Containing Nanobioglass On Postoperative Sensitivity Of Posterior Composite Restorations. A Randomized Trial

Not Applicable

• Conditions: Oral Health

• Registration Number: PACTR201906464023194
• Lead Sponsor: Faculty Of Oral and Dental Medicine Cairo University.

Brief Summary

The nanobioglass containing self-etch adhesives scored a significantly lower postoperative sensitivity ratings than the nanobioglass free one (P< 0.05). The nanobioglass containing self-etch adhesive had a significantly lower postoperative sensitivity scores than the nanobioglass free one at the 1 day and the 1 week evaluation periods, while at the 1 months and 3 months evaluation periods, both materials did not possess any significant difference. Thus the problem of postoperative sensitivity after resin composite restorations could be solved by the addition of bioglass nanoparticles into dental adhesives.

Inclusion Criteria

Moderate to deep proximal primary carious lesions in posterior teeth.
Patients showing no signs of spontaneous dental or orofacial pain.
Selected teeth should not have any signs or symptoms of pulpal and periapical disease.
Selected teeth should have an occlusal contact with natural or crowned antagonist teeth so that it could be tested for post-operative pain during chewing of food.

Exclusion Criteria

Previously restored teeth showing secondary caries.
Defective restorations that need a replacement for esthetic reasons.
Occlusal disturbances or temporo-mandibular joint problems involving gingival recession or alveolar bone loss.
Patients taking analgesics that could alter their normal pain perception level.
Patients on orthodontic treatment.
Medical, psychiatric, or pharmaco-therapeutic histories that might compromise the study protocol including chronic use of anti-inflammatory, analgesic, psychotropic drugs.
Abutment teeth for a fixed or removable prosthesis.
Pregnancy or breastfeeding, acute and chronic systemic diseases, immune-compromised patients.
Medical problems preventing the participant from showing up to return the Visual Analog Scale (VAS) in its due time.
