Brief summary

The present study aims to evaluate the impact of detecting active initial caries lesions in primary teeth regarding effectiveness, cost-effectiveness, applicability (acceptability and satisfaction) and quality of life. For this, 248 children 3-6 years with complete primary dentition will be examined and treated in a mobile dental unit, which will temporarily be parked in public schools of Sao Paulo. The caries detection will be conducted using the International Caries Detection and Assessment System (ICDAS) and, depending on allocation, an adjunct criterion for caries activity assessment. Children will be randomized in two groups according to the caries threshold to be detected: Group A (only advanced lesions will be detected and treated, independently of their activity status) and Group B (all caries lesions, including initial ones, will be detected and all active lesions will be treated). After this, the treatment plan for each child will be made according to strategies mentioned above. Data concerning the cost-effectiveness of the procedures, acceptability / satisfaction of children and quality of life will be collected after diagnosis, after the end of treatment and 12 and 24 months from the initial examination. For comparison between groups, multilevel regression analyses will be performed. The primary outcome will be sites which need of operative treatment during the follow-up periods and the secondary outcomes will be the cost-effectiveness of each strategy, the acceptability / satisfaction of the child and the impact on quality of life.

Interventions

OTHERAdvanced caries lesions detection (no activity assessment)

The diagnosis strategy will based on detection of only moderate and advanced caries lesions (ICDAS scores 3 to 6). Initial caries lesions will be considered as sound surfaces. Caries activity status will not be evaluated. Clinical decision-making will be proposed for all lesions detected, based on evidence-based protocols.

OTHERAll caries lesions detection (+activity assessment)

The diagnosis strategy will based on detection of initial, moderate and advanced caries lesions (ICDAS scores 1 to 6). Caries activity status will be also evaluated. Clinical decision-making will be proposed for all active lesions detected, based on evidence-based protocols. inactive caries lesions will not be treated.

Design outcomes

Primary

MeasureTime frameDescription
Incremental number of dental surfaces with operative treatment needsAfter 12 and 24 months from allocationThis outcome will be assessed by the new caries lesions and / or progression of lesions previously diagnosed / treated and number of treated surfaces which will need restoration replacement, endodontic treatment or extraction after the initial treatment.

Secondary

MeasureTime frameDescription
Cost-efficacyAfter 12 and 24 months from the allocationThe costs of the diagnostic strategy will be calculated and compared with threshold values for intervention cost-effectiveness by region, determined by World Health Organization.
Discomfortimmediately after the allocation and after 12 and 24 monthsParticipants' discomfort, measured by a validated scale (Wong-Baker scale).
Impact of oral health on quality of life12 and 24 months after the allocationImpact of oral health on quality of life of the children participants in the study, measured by a validated questionnaire (ECOHIS).

Other

MeasureTime frameDescription
CostsImmediately after allocationThe costs of each diagnostic strategy and treatment based on that will be calculated, regarding time of each clinical session, materials used, duration of treatment and possible repetitions.
