Clinical Trial Summary

A post market clinical follow up study (PMCF) with Adhese Universal DC is planned to ensure the safety and efficacy of the product. It is a study with two arms. Inlays and onlays for molars and premolars will be luted with Adhese Universal DC or Adhese Universal.

Description:

This study aims to assess the long-term safety of Adhese Universal DC in terms of tooth vitality and failure rate of placed restorations. Tooth vitality is an indicator for the health status of the dental pulp. A vitality test is performed to acquire information about the vitality of teeth. A healthy dental pulp offers a positive response to the vitality test. Once the dental pulp is injured an irreversible inflammatory reaction starts with a possible necrosis of the dental pulp. Pulpa necrosis is followed by a negative response to the vitality test.

• Participant wishes a restoration within the scope of the study (signed informed consent after detailed explanation and study of the patient information)
• 2-operative discomfort of the tooth to be restored should not exceed 3 on the visual analogue scale (VAS) (0=no pain, 10=maximum conceivable pain) due to temperature stimulus or bite sensitivity

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	postoperative hypersensitivity	assessed by tests with thermal stimuli and occlusal forces (during biting) determined by VAS (Visual Analog Scale) following the FDI criteria on a scale from 1 "very good" to 5 "unacceptable"	Baseline to 60 months
Secondary	loss of vitality of restored teeth	assessed by a cold stimuli test (cotton pellet and refrigerating spray) following the FDI criteria on a scale from 1 "very good" to 5 "unacceptable"	Baseline to 60 months
Secondary	fracture rate of restored teeth	assessed following the FDI criteria on a scale from 1 "very good" to 5 "unacceptable"	Baseline to 60 months
Secondary	retention/fracture rate of restorations	assessed following the FDI criteria on a scale from 1 "very good" to 5 "unacceptable"	Baseline to 60 months
Secondary	marginal quality	assessed following the FDI criteria on a scale from 1 "very good" to 5 "unacceptable"	Baseline to 60 months
