Deelnemersgroep / Arm |
Interventie / Behandeling |
|---|---|
|
Ander: Group I
Total-etch mode with 35% phosphoric acid
|
35% phosphoric acid was applied to enamel and dentin for 10 s, washed and dried for 5 s.
The universal adhesive, Clearfil Universal Bond Quick (CBQ) was applied to enamel and dentin surfaces with a single-use applicator, then gently air-dried for 5 s without waiting, and light-cured for 10 s.
|
|
Ander: Group II
Selective-etch mode with 35% phosphoric acid
|
35% phosphoric acid was used only on enamel for 10 s, then washed and dried for 5 seconds.
Subsequently, the adhesive was applied in a similar manner to the TE-A group.
|
|
Ander: Group III
Total-etch mode with laser (Er,Cr:YSGG)
|
the enamel margin and dentin surfaces of lesions were irradiated with an Er,Cr:YSGG laser (2780 nm, Waterlase MD, BioLase Technology, Inc., San Clemente, CA).
Then the adhesive was applied in a similar manner to the TE-A group.
|
|
Ander: Group IV
Selective-etch mode with laser (Er,Cr:YSGG)
|
The laser system was applied in the same way as described in the TE-L group only on enamel surface.
Subsequently, the adhesive was applied in the same way as described in the TE-A group.
|
|
Ander: Group V
Self-etch mode
|
Universal adhesive system (CBQ) was applied to enamel and dentin surfaces without any previous etching.
Then gently air-dried for 5 s without waiting, and light-cured for 10 s.

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Retention,
Tijdsspanne: From baseline to 2 year the change of restorations was evaluated
|
The retention criterion determines how long a restorative material functions in the oral environment, it is the most important criterion that shows the success of the material. Alpha: The restoration is present. Charlie: The restoration is absent. |
From baseline to 2 year the change of restorations was evaluated
|
|
Marginal Discoloration
Tijdsspanne: From baseline to 2 year the change of restorations was evaluated
|
The marginal discoloration that occur at the edge staining restoration boundaries are generally thought to be due to microleakage. Alpha: No discoloration at margins. Bravo: Shallow discoloration, clinically acceptable. Charlie: Deep discoloration clinically unacceptable. |
From baseline to 2 year the change of restorations was evaluated
|
|
Marginal Adaptation
Tijdsspanne: From baseline to 2 year the change of restorations was evaluated
|
Marginal adaptation is achieved by fully ensuring the integrity of the tooth-restoration joint border. Alpha: Restoration is closely adapted to the tooth. Bravo: Visible evidence of a crevice along the margin, dentin not exposed, clinically acceptable. Charlie: Explorer penetrates into crevice, dentin is exposed; clinically unacceptable. |
From baseline to 2 year the change of restorations was evaluated
|
|
Color match
Tijdsspanne: From baseline to 2 year the change of restorations was evaluated
|
Color match is the evaluation of the restoration according to the darkening or lightening of the color, taking into account the tooth tissue surrounding restoration. Alpha:Matches tooth. Bravo: Acceptable mismatch. Charlie:Unacceptable mismatch. |
From baseline to 2 year the change of restorations was evaluated
|
|
Post-op Hypersensitivity
Tijdsspanne: From baseline to 2 year the change of restorations was evaluated
|
Determination of sensitivity after restorations are placed.
Alpha: Absent.
Charlie: Present; clinically unacceptable.
|
From baseline to 2 year the change of restorations was evaluated
|
|
Secondary Caries
Tijdsspanne: From baseline to 2 year the change of restorations was evaluated
|
Secondary caries is the progression of caries in the tooth tissue adjacent to the restorations. Caries formation means restoration failure. Alpha: Absent. Charlie: Present; clinically unacceptable. |
From baseline to 2 year the change of restorations was evaluated
