Brief Summary:
Objectives: To assess the beneficial and harmful effects of two recall intervals on caries incidence (primary outcome) in preschool children with high caries risk. The level of anxiety, oral health related quality of life (OHRQoL), time and cost (secondary outcomes) according to each interval will also be assessed. Methods: The sample will consist of 224 children between 3-5 years of age, of both genders, with high caries risk according to the clinical criteria adapted from the Municipal Health Secretary of São Paulo. Children will be randomly allocated into two study groups: Group 1 (G1) - oral clinical examination + orientation for oral health and diet in return for 4 months; and Group 2 (G2) - oral clinical examination + orientation for oral health and diet in return for 8 months. An examiner calibrated and blinded to the study groups and the secondary outcomes will perform the clinical examinations, which consist of: gingival bleeding index, dental plaque index, detection of caries and its activity according to the ICDAS (International Caries Detection and Assessment System) and the clinical features of active and inactive caries lesions will be associated with the criteria discribed in ICDAS Commitee manual. An external dentist will conduct the assessment of the anxiety levels assessed by the Facial Image Scale, the OHRQoL measured by B-ECOHIS, the time and costs. All groups will be followed for an initial period of 16 months, totaling four follow-up visits for G1 and two follow-up visits to the G2. All analyzes will be performed by intention to treat (ITT) and considering the sensitivity analysis to assess the differences between the ITT analyzes and analyzes of complete cases.

Detailed Description:
An examiner calibrated and blinded to the study groups and the secondary outcomes will perform the clinical examinations, which consist of: the gingival bleeding index, dental plaque index, detection of caries and its activity according to the ICDAS (International Caries Detection and Assessment System) and the clinical features of active and inactive caries lesions will be associated with the criteria discribed in ICDAS Commitee manual. An external dentist will conduct the assessment of the anxiety levels assessed by the Facial Image Scale, the OHRQoL measured by B-ECOHIS (Brazilian Early Childhood Oral Health Impact Scale), the time and costs. All groups will be followed for a period of 36 months. All analyzes will be performed with the intention of treatment (ITT) and considering the sensitivity analyzes to assess the differences between the ITT analyzes and the complete cases analyzes.

Primary Outcome Measures :
  1. Dental caries incidence [ Time Frame: Baseline, 4 months and 8 months ]
    Dental caries will be assessed using the ICDAS criteria (Ismail AI, Sohn W, Tellez M, Amaya A, Sen A, Hasson H, et al. The International Caries Detection and Assessment System (ICDAS): an integrated system for measuring dental caries. Community Dent Oral Epidemiol 2007; 35: 170-8).


Secondary Outcome Measures :
  1. Level of anxiety [ Time Frame: Baseline, 4 months and 8 months ]
    Level of anxiety will be assessed using the Facial Image Scale (Buchanan H, Niven N. Validation of a facial image scale to assess child dental anxiety. Int J Paediatr Dent 2002;12:47-52)

  2. Oral health related quality of life [ Time Frame: Baseline, 4 months and 8 months ]
    Oral health related quality of life will be assessed using the Brazilian validation of the ECOHIS (Scarpelli AC, Oliveira BH, Tesch FC, Leão AT, Pordeus IA, Paiva SM. Psychometric properties of the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS). BMC Oral Health. 2011; 11:19).

  3. Time [ Time Frame: Baseline, 4 months and 8 months ]
    The time in minutes, used in the recall interval visits, will be recorded in four categories: time spent on clinical examination including prophylaxis, hygiene and diet orientations, and time spent when the patient miss the recall visit. The total time will correspond to the sum of these categories.

  4. Costs [ Time Frame: Baseline, 4 months and 8 months ]
    Costs in real (continuous variable) will be recorded in three categories: salary of the dentist and dental assistant paid in public dental services in São Paulo, cost of dental materials/products used in the appointment.
