Radiographic Assessment of Glass Ionomer Restorations With and Without Prior Application of Nano Silver Fluoride in Occlusal Carious Molars Treated With Partial Caries Removal Technique

Cairo University (CU)

Status: Completed

Conditions: Partial Dentin Caries Removal

Treatments: Other: nano silver fluoride solution

Study type: Interventional

Funder types: Other

Identifiers

NCT03193606

CEBC-CU-2017-06-15

Details and patient eligibility

About

eligible teeth will be randomly divided into two groups to be treated with incomplete caries excavation (A), where (A1) represents teeth to be treated with application of Nano silver fluoride solution on remaining carious dentin prior to final permanent glass ionomer restoration application, (A2) represents comparator group to be restored without Nano silver fluoride application prior to restoration. Every participant will receive both the intervention and control treatment. Image of radiographic density of remaining carious dentin will be evaluated using PSP plate at baseline immediately after restoration and after 6 months after restorative procedures.

The null hypothesis tested is that application of Nano silver fluoride solution prior to glass ionomer restoration will not increase radiopacity of the underlying dentin treated by incomplete carious removal technique compared to that of direct glass ionomer restoration without prior application of Nano silver fluoride.

Enrollment: 22 patients

Sex: All

Ages: 16 to 35 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients presenting with at least 2 teeth with active carious lesions limited to the occlusal surface of molars at risk of pulp exposure during direct complete excavation (primary caries lesion involving more than half of the entire dentin thickness determined radiographically).
• Signs and symptoms indicative of pulp vitality, i.e. a positive response to thermal stimulation during a cold test
• Absence of apical pathosis, clinical diagnosis of pulp exposure, fistula, swelling of periodontal tissues.

Exclusion criteria

• Teeth with spontaneous pain or sensitivity to percussion.
• Teeth with periodontal lesions, internal or external root resorption, mobility of tooth, sinus opening, or abscessed tooth.
• Radiographic examination revealed, interrupted or broken lamina dura, widened periodontal ligament space, periapical radiolucency.
• patients with systemic medical conditions
• pregnant females
