Official title
Longitudinal Evaluation of Minimally Invasive Protocols for the Prevention and Control of Dental Caries in Brazilian Schoolchildren: A Multicenter Study Protocol
Overview
This multicenter longitudinal interventional study aims to evaluate minimally invasive protocols for the prevention and control of dental caries in Brazilian schoolchildren under routine public health conditions. In the first phase, 50,000 children aged 6 to 12 years from public schools in five Brazilian cities will undergo dental screening using ICDAS criteria and receive preventive and educational oral health measures. In the longitudinal treatment phase, 2,500 children diagnosed with active carious lesions will be managed according to ICDAS-based minimally invasive treatment protocols. Participants will be followed every three months for up to 24 months.
Detailed description
This is a pragmatic, multicenter, non-randomized, longitudinal interventional study coordinated by the Brazilian Association of Pediatric Dentistry (ABOPED) in five Brazilian cities: Santos, Ponta Grossa, Brasília, Fortaleza, and Belém. The study aims to evaluate the longitudinal clinical behaviour of carious lesions and the performance of minimally invasive oral health strategies under routine school-based public health conditions.
In the first phase, 50,000 children aged 6-12 years enrolled in public schools will undergo dental screening using the International Caries Detection and Assessment System (ICDAS). All participants will receive preventive and educational measures, including oral health counselling, supervised toothbrushing with fluoridated toothpaste (1100 ppm F), toothbrushes, toothpaste, and application of Duraphat® fluoride varnish to permanent molars and incisors.
Children identified with active carious lesions classified as ICDAS 1-6 and meeting the eligibility criteria will enter the longitudinal minimally invasive treatment phase. A total of 2,500 participants will be managed according to ICDAS-based treatment protocols:
Protocol 1: preventive fluoride varnish application; Protocol 2: fluoride varnish applications for active white spot lesions; Protocol 3: ART sealants with high-viscosity glass ionomer cement for ICDAS 3 lesions; Protocol 4: atraumatic restorative treatment with high-viscosity glass ionomer cement for ICDAS 4-6 lesions, with optional use of PapacarieDUO® during selective caries removal.
Participants will be followed every three months for up to 24 months.
Interventions
- Procedure Fluoride Varnish Application (Preventive Protocol)
Preventive application of Duraphat® fluoride varnish on permanent molars and incisors, with quarterly maintenance applications. - Procedure Fluoride Varnish for Active Enamel Lesions
Four weekly fluoride varnish applications for active white spot lesions, followed by quarterly maintenance applications. - Procedure Atraumatic Restorative Treatment (ART) Sealant
Placement of ART sealants with high-viscosity glass ionomer cement for ICDAS 3 lesions, followed by quarterly fluoride varnish applications. - Procedure Atraumatic Restorative Treatment (ART)
Atraumatic restorative treatment with high-viscosity glass ionomer cement for ICDAS 4-6 lesions, with optional use of PapacarieDUO® and quarterly fluoride varnish applications.
Primary outcome measures
- Control of Caries Activity [Time frame: Baseline, 3, 6, 9, 12, 15, 18, 21, and 24 months]
Secondary outcome measures (3)
- Survival and Integrity of ART Sealants and Restorations [Time frame: 3, 6, 9, 12, 15, 18, 21, and 24 months]
- Inactivation of Active White Spot Lesions [Time frame: 3, 6, 9, 12, 15, 18, 21, and 24 months]
- Adherence to Preventive Oral Health Measures [Time frame: 3, 6, 9, 12, 15, 18, 21, and 24 months]
