NCT05583682

Brief Summary

The aim of this randomised controlled double-blinded, split mouth, single-center clinical trial was to evaluate the 18-month clinical performance of nano-filled resin-modified glass ionomer and sub-micron hybrid resin composite restorations in lower first permanent teeth of pediatric patients.

Outcome Measures

Primary Outcomes (8)

  • Color Match

    Color match of dental restorations were observed with a Vita Scale visually by two calibrated examiners. Restorations were scored Alfa, Bravo or Charlie according to Modified USPHS criteria. ( Alfa: Imperceptible in room light in one-second glance, Bravo: Perceptible mismatch with the Vita scale but clinically acceptable, Charlie: Esthetically unacceptable)

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Marginal Discoloration

    Marginal discoloration of dental restorations were observed by two calibrated examiners with visual inspection. Restorations were scored Alfa, Bravo or Charlie according to Modified USPHS criteria. (Alfa: No existing marginal discoloration, Bravo:Presence of discoloration at margins between restoration and tooth structure; discoloration does not penetrate towards the pulp, Charlie: The discoloration penetrated along the margins of the restoration in a pulpal direction.

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Anatomic Form

    Anatomic form of dental restorations were observed by two calibrated examiners by visual inspection and explorer. Restorations were scored Alfa, Bravo or Charlie according to Modified USPHS criteria. (Alfa: The restoration is not under-contoured, Bravo: The restoration is under-contoured, but there is no dentin or base exposed, Charlie: Sufficient restorative material is missing so that dentin or base is exposed.

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Marginal Integrity

    Marginal integrity of dental restorations were observed by two calibrated examiners with visual inspection and explorer. Restorations were scored Alfa, Bravo or Charlie according to Modified USPHS criteria. (Alfa: No visible evidence of a crevice along the margin into which an explorer will catch, Bravo: The explorer catches a crevice along the margin but there is no exposure of dentin or base, Charlie: Visible evidence of a crevice with exposure of dentin or base.)

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Recurrent Decay

    Recurrent decay of dental restorations were observed by two calibrated examiners with visual inspection. Restorations were scored Alfa or Charlie according to Modified USPHS criteria. (Alfa: No evidence of recurrent caries along the margin of the restoration, Charlie: Evidence of caries along the margin of the restoration.)

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Fracture

    Fracture of dental restorations were observed by two calibrated examiners by visual inspection with explorer. Restorations were scored Alfa, Bravo or Charlie according to Modified USPHS criteria. (Alfa: No fracture, Bravo: Small chip, but clinically acceptable, Charlie: Failure due to bulk restoration fracture.)

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Surface Texture

    Surface texture of dental restorations were observed by two calibrated examiners by visual inspection and explorer. Restorations were scored Alfa, Bravo or Charlie according to Modified USPHS criteria. (Alfa: Enamel like surface, Bravo: Surface rougher then enamel, clinically acceptable, Charlie: Surface unacceptable rough.)

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

  • Postoperative Sensitivity

    Postoperative sensitivity of patients were assessed by two calibrated examiners by cold thermal test. Restorations were scored Alfa or Charlie according to Modified USPHS criteria. (Alfa: No sensitivity, Charlie: Sensitivity present.)

    Changes of dental restorations regarding color match were observed at 1st week, 6th,12th and 18th month recalls.

Study Arms (2)

Nano-filled resin-modified glass ionomer restoration

EXPERIMENTAL

Other: Dental restoration

Sub-micron hybrid resin composite

EXPERIMENTAL

One of the carious mandibular first molar teeth will be restored according to randomisation with sub-micron hybrid resin composite restorative material (Spectrum TPH3, Dentsply Caulk, USA)

Other: Dental restoration

Interventions

Restoration of carious mandibular first molar teeth are restored either with nano-filled resin modified glass ionomer or sub-micron resin composite restorative material
