Efficacy of Proximal Caries Infiltration

Not Applicable

Completed

• Conditions: Dental Health; Caries

• Registration Number: NCT01726179
• Lead Sponsor: DMG Dental Material Gesellschaft mbH

Brief Summary

The goal of the project is to investigate the clinical efficacy of management of early caries lesions by resin infiltration and to further scrutinize the patient stress experiences.

Detailed Description

The aim of this study is to test the clinical efficacy of caries infiltration to arrest proximal caries lesions in primary molars. It was hypothesized that infiltrated lesions (test lesions) will progress significantly less than non infiltrated lesions (control lesions). Additionally, it was hypothesized that dental anxiety and stress related to caries infiltration will be significantly less than dental anxiety related to a conventional restorative procedure. The study will be a controlled clinical trial with a split mouth design and blind evaluation of the outcome (caries progression). Caries progression will be evaluated annually, 12, 24, and 36 months after treatment.

Primary Outcome Measures

Name	Time	Method
Caries progression rate	1 year	Radiographic evaluation of infiltrated and control caries lesions to evaluate caries progression. This is done by pairwise comparison of digital bitewing radiographs by one calibrated, blinded examiner.

Secondary Outcome Measures

Name	Time	Method
Caries progression rate	2 years, 3 years	Radiographic evaluation of infiltrated and control caries lesions to evaluate caries progression in long term. This is done by pairwise comparison of digital bitewing radiographs by one calibrated, blinded examiner.
Stress reaction during treatment	Immediate	To evaluate dental anxiety and stress reactions in relation to the caries infiltration procedure in comparison with a dental examination appointment and conventional resin restoration appointment.; A facial image scale with five faces ranging from very happy (1) to very unhappy (5) will be used.
Caries risk	Baseline, 6 months, 1 year, 2 years, 3 years	Caries risk is asses based on caries index (Nyvad criteria), proximal plaque index (0 = no visible plaque; 1 = visible plaque) and gingival bleeding index (0 = no bleeding after flossing; 1 = bleeding after flossing), dietary habits, and exposition to fluorides based on the Cariogram model.
