Clinical Performance, Streptococcus Mutans Count, and Salivary pH for Cention-N, Zirconomer, and Resin-modified Glass Ionomer in Class I Restoration of Primary Molars

A vital aspect of overall health is dental health. Recurrent effects of oral disease on eating, sleeping, working, and social duties are subtle and widespread, and they collectively form a hidden pandemic.

The most widely used substitute for amalgam is glass ionomer cement (GIC), which has recognized the capacity to produce fluoride and played a major role in their growing application in dentistry.

The components of resin-modified GICs (RMGIC) are the same as those of ordinary glass-ionomers: polyacid, water, and basic glass powder. A monomer component and related initiator system are also present. RMGICs were created when monomeric ingredients such as 2-hydroxyethyl methacrylate (HEMA), urethane dimethacrylate (UDMA), and bisphenol-A-glycidyl methacrylate (Bis-GMA) were added to the ionomer composition.

Inclusion criteria

• Children aged between 4-9 years.
• Children who have Class I lesions in both the maxillary and mandibular arches.
• Primary molar teeth had class I carious lesions in occlusal pits and fissures; the gap between intercuspal surfaces should not be exceeded during cavity preparation.
• Primary molars free of periapical pathosis.
• Primary molars free root resorption.

Exclusion criteria

• Primary molars with preapical pathosis or hypersensitivity.
• Primary molars with periodontal diseases or mobile molar tooth that indicated for extraction.
• Nonfunctioning teeth with no opposing dentition; heavy occlusion or signs of severe attrition; and endodontically treated teeth.
