Eligibility
Age
7 Years to 10 Years
Inclusion criteria
Inclusion criteria: Healthy children, 7 to 10 years-old, with molar incisor hypomineralization diagnosed according to the European Academy of Pediatric Dentistry criteria. Patients must present at least one permanent first molar with creamy-whitish or yellow-brownish demarcated opacity without post-eruptive breakdown or dentin caries.
Exclusion criteria
Exclusion criteria: Children with other enamel developmental defects than molar incisor hypomineralization, with fixed orthodontic appliance or who are unable to cooperate during dental treatment will be excluded.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The effect of sealing on the prevention of post-eruptive breakdown at the tooth level, will be assessed by tactile-visual examination of the tooth surfaces according to the criteria proposed by the European Academy of Pediatric Dentistry following the scores described below: Score 1: creamy-whitish opacity = absence of post-eruptive breakdown; Score 2: yellow-brownish opacity = absence of post-eruptive breakdown; Score 3: lost of enamel integrity restricted to enamel = presence of post-eruptive breakdown; Score 4: lost of enamel integrity exposing dentin = presence of post-eruptive breakdown; Score 5: presence of an atypical restoration = presence of post-eruptive breakdown. The main outcome, absence/presence of post-eruptive breakdown, will be assessed every 6 months, along the total period of 36 months. The effect of the TEST intervention in preventing post-eruptive breakdown will be assessed comparing the proportion of teeth with no post-eruptive breakdown between TEST and CONTROL group using the Kaplan-Meier survival analysis. | — |
Secondary
| Measure | Time frame |
|---|---|
| The retention rate of fissure sealant, at the tooth level, assessed by tactile-visual, using dental mirror and explorer, examination of the tooth surfaces, every 6 months along the total period of 36 months. The retention rate of the sealants will be assessed according to Oulis and Berdouses (Eur Arch Paediatr Dent. 2009;10(4):211–7). At the tooth level, the sealant will be scored as: 1- totally retained; 2- partially retained; or 3- totally lost. The success rate of the TEST intervention will be assessed comparing the proportion of teeth with totally retained sealant between TEST and CONTROL group using the Kaplan-Meier survival analysis.;The dentin caries prevention rate, at the tooth level, assessed by tactile-visual, using dental mirror and explorer, examination of the tooth surfaces, every 6 months along the total period of 36 months. Dentin caries prevention rate: The presence or absence of dentin caries will be assessed according to Nyvad criteria (Caries Res. 1999;33(4):252-60). At the tooth level, dentin caries will be considered present when the caries score is 3 or 6 represented by the presence of cavitation, exposing dentin. The effect of the TEST intervention in preventing dentin caries will be assessed comparing the proportion of teeth with no dentin caries between TEST and CONTROL group using the Kaplan-Meier survival analysis. | — |
