Immediate and Delayed Dentin Sealing Effect on Partial Crowns

NCT03443583 | Completed

• 1 other identifier: NL45130
• Study Type: interventional
• Target: 30
• Locations: 0 countries
• Sites: N/A

Brief Summary

Immediate Dentin Sealing as an adjunct to adhesive cementation of all ceramic restorations is proposed and executed in several studies, but there is very limited evidence to support its effectiveness. It is presumed that IDS both reduces postoperative sensitivity and increases the bond strength to dentin as compared to DDS.

Conditions

Adhesion; Tooth; Crown; Luting; Immediate Dentin Sealing

Outcome Measures

Primary Outcomes (1)

• Survival

  Survival of the restorations

  3 year

Secondary Outcomes (1)

• Quality of the restorations

  3 year

Interventions

Immediate Dentin Sealing or Delayed Dentin Sealing OTHER

The main difference between the IDS and DDS technique lies in the fact that in IDS, a thin layer of bonding resin is applied immediately after tooth preparation and prior to impression taking, whereas in DDS this layer is applied immediately before cementation of the restoration.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients should be over 18 years of age, in reasonable to good general health, as expressed by an ASA-score I or II (de Jong and Abraham-Inpijn, 1994).This ASA-score is already known before participation, due to regular check-ups;
• Patients should have an indication for at least two indirect ceramic restorations on vital teeth.

You may not qualify if:

• ASA-score III or higher;
