Outcome Measures

Primary Outcomes (1)

  • Incidence of secondary caries

    The primary outcome of this study will be the evaluation of secondary caries incidence at 3, 6, and 12 months following restoration. Assessment will be carried out using the United States Public Health Service (USPHS) criteria, with restorations scored on a scale ranging from Alpha (clinically excellent) to Delta (clinically unacceptable. Each restoration will be scored as Alpha (A) if there is no evidence of secondary caries and the tooth-restoration interface remains intact. A score of Bravo (B) will indicate a questionable or suspicious area, such as slight marginal staining without definite cavitation. Charlie (C) will be assigned when definite secondary caries are observed, including softness or cavitation at the restoration margin, necessitating replacement of the restoration. Delta (D) will be used for severe carious lesions extending beneath the restoration, requiring immediate intervention.

Secondary Outcomes (1)

  • clinical evaluation of restoration fracture

Study Arms (2)

Alkasite-based Restorations (Cention N)

EXPERIMENTAL

The children assigned to this intervention group will have alkasite-based restorations for the treatment of Class I carious lesion in primary molars.

Other: Alkasite-based composite restorations

ACTIVE COMPARATOR

The children assigned to the comparator group will undergo class I cavity restorations using nano-hybrid resin composite

Other: Nano-hybrid resin composite

Interventions

Alkasite-based restorations will be used in the treatment of class I carious lesion in primary molars.

Also known as: Cention N
Alkasite-based Restorations (Cention N)

Nanohybrid composite will be used in the restoration of Class I carious lesions in primary molars.

Nano-hybrid composite resin restoration (TPH Spectra ST Universal Composite).
