Primary Outcome Measures:
  • dental caries [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • dental plaque [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
    Dental plaque accumulation after short and long term analysis

Estimated Enrollment: 220
Study Start Date: July 2011
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: multilevel filaments toothbrush
Children will brush with anteroposterior toothbrushing and a modified toothbrush (multilevel filaments)
Behavioral: modified toothbrush with multilevel filaments
After the allocation of patients in this group they were instructed to brush their first molars erupt with the brushing technique anteroposterior.
Other Name: stages, oral b
Active Comparator: cross toothbrushing
Children will brush with cross toothbrushing.
Behavioral: cross toothbrushing
Children allocated to the group multi-bristled brush will be modified compared to the results of the group cross toothbrushing technique
Other Name: buccal-lingual technique

Detailed Description:
220 children between 5-7 years with at least one permanent molar erupting will be selected, with a maximum score of ICDAS 3. These children will be randomly allocated into two groups according to the technique adopted. The teeth will be evaluated by ICDAS, laser fluorescence (DIAGNOdent), QLF and subtraction radiography at baseline and after 15 days, 3, 6, 9,12,18,24 months.

Ages Eligible for Study:   5 Years to 7 Years

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • erupting primary permanent molar

Exclusion Criteria:

  • caries ( ICDAS 4,5 and 6),
  • enamel defects,
  • sealant,
