NCT07052526

Brief Summary

This randomized controlled clinical trial aims to evaluate and compare the retention, caries prevention, microleakage, and fluoride release of three types of pit and fissure sealants-hydrophilic, nanofilled hydrophobic, and conventional hydrophobic-applied to partially erupted first permanent molars in children aged 5 to 7 years. The study uses a split-mouth design and includes both clinical and laboratory evaluations over an 18-month period. Outcomes will assess sealant effectiveness with and without the use of a bonding agent.

Outcome Measures

Primary Outcomes (2)

  • Retention

    retention is evaluated using CCC Index (Color, Coverage, and Caries) This scale is used to assess sealant retention and caries status during follow-up evaluations. Score Description Retention Caries Status Interpretation 0 Sealant completely retained no caries Full retention Best outcome 1. Partial sealant loss no caries Partial loss Acceptable 2. Sealant completely lost no caries Total loss Less ideal 3. Sealant partially or totally lost caries present Partial or total loss Worst outcome

    18 months

  • Caries

    Caries Incidence: 3, 6, 12, 18 months, t each recall (3, 6, 12 months), evaluate each sealed tooth using the CCC score: If the sealant is completely intact and no caries is visible → score = 0 If the sealant is partially gone but no decay → score = 1 If sealant is lost but still no decay → score = 2 If sealant is lost/partial and there is decay → score = 3

    18 months

Secondary Outcomes (2)

  • Microleakage

    3 months

  • Fluoride release

    2months

Study Arms (3)

Helioseal Fplus

EXPERIMENTAL

Participants in this arm will receive the Helioseal F Plus resin-based sealant, applied to occlusal surfaces of permanent molars. The sealant will be applied according to the manufacturer's

Other: Prevention

1 - Hydrophilic Sealant (Embrace WetBond)

EXPERIMENTAL

Participants will receive Embrace WetBond sealant, a moisture-tolerant resin sealant applied to slightly moist occlusal surfaces. The sealant is light-cured for 20 seconds

Other: Prevention of caries

Denu seal

EXPERIMENTAL

Participants in this arm will receive Denuseal, a fluoride-releasing sealant, applied to occlusal surfaces of permanent molars under dry conditions. The sealant will be light-cured for 20 seconds.

Other: Prevention therapy

Interventions

Conventional Hydrophobic Sealant (Helioseal F - Control) will be used as a positive control; applied to partially erupted molars with and without bonding in a split-mouth design.

Also known as: Helioseal-F plus
