2. Demarcated opacity in primary teeth increases the prevalence of molar incisor hypomineralization
Abstract This cross-sectional study aimed to assess the prevalence of molar incisor hypomineralization (MIH) and its relationship with the number of primary teeth with developmental defects of enamel (DDE). A representative population-based sample of 731 schoolchildren was randomly selected from the public school system in Curitiba, Brazil. Schoolchildren ag

3. A 3-D evaluation of transverse dentoalveolar changes and maxillary first molar root length after rapid or slow maxillary expansion in children
RESUMO Objetivo: o objetivo do presente trabalho foi realizar um estudo clínico randomizado comparando os efeitos da expansão rápida da maxila (ERM) e da expansão lenta da maxila (ELM). O comprimento radicular do primeiro molar superior permanente e o deslocamento dentro do alvéolo foram estudados por meio de imagens de tomografia computadorizada de f

5. Survival of sealants in molars affected by molar-incisor hypomineralization: 18-month follow-up
Abstract The objective of this study was to evaluate the clinical survival of sealants applied in first permanent molars (FPMs) affected by molar-incisor hypomineralization (MIH), at 18 months of follow-up. Forty-one first permanent molars were selected from 21 children, 6–8 years of age. MIH was classified by one calibrated examiner (kappa = 0.80) accordi

6. Molar incisor hypomineralization (MIH): conservative treatment management to restore affected teeth
The purpose of this study was to evaluate the 12-month clinical performance of glass ionomer restorations in teeth with MIH. First permanent molars affected by MIH (48) were restored with glass ionomer cement (GIC) and evaluated at baseline, at 6 and at 12 months, by assessing tooth enamel breakdown, GIC breakdown and caries lesion associations. The data wer

7. Influence of deciduous molar hypomineralization on the development of molar-incisor hypomineralizarion
Defects similar to Molar-Incisor Hypomineralization (MIH) in second primary molars can be found in the literature, being recently named Deciduous Molar Hypomineralization (DMH). Researchers have stated that the presence of DMH in primary dentition represents a risk for MIH in permanent teeth. The explanation for this association is probably related to the et

8. Efetividade do uso de escova infantil com cerdas multinível associada à técnica de escovação anteroposterior na remoção de biofilme em primeiros molares permanentes em erupção / Effectiveness of using childrens toothbrush with multilevel filaments associated with anteroposterior toothbrushing in removing dental plaque from occlusal surfasse of erupting permanente molars
O presente trabalho objetivou: 1) comparar a efetividade da técnica de escovação anteroposterior com escovas de design modificado e cerdas multinível com a técnica de escovação transversal com escova infantil convencional de cerdas retas com, quanto à remoção de biofilme em superfícies oclusais de molares permanentes em erupção, em curto e longo

9. Anteroposterior dentoalveolar effects with cervical headgear and pendulum appliance: a systematic review
AIM: The aim of this systematic review was to compare the maxillary dental effects of cervical headgear and pendulum appliance during distalization of permanent maxillary first molars. METHODS: A literature survey from databases covering the period from 1956 to August 2008 was carried out. Randomized controlled trials (RCT) and controlled clinical trials (CC

10. A 12-month clinical evaluation of pit-and-fissure sealants placed with and without etch-and-rinse and self-etch adhesive systems in newly-erupted teeth
OBJECTIVES: The objective of this one-year clinical study was to investigate the effect of two adhesive systems (Adper Single Bond, a two-step etch-and-rinse and Clearfil SE Bond, a two-step self-etch system) on pit-and-fissure sealant retention in newly-erupted teeth. This study compared the success of the sealants in mesial and distopalatal grooves with an

11. Comprehensive intermaxillary tooth width proportion of Bangkok residents
Proper occlusion depends on the correct width ratio between upper and lower teeth, known as Bolton's ratio. In fact, this ratio can be calculated for each pair of teeth from the central incisor to the first permanent molar. This set of ratios, known as comprehensive cumulative percentage ratios (CPRs), can be used not only to determine which tooth or teeth h

12. Anesthetic technique for inferior alveolar nerve block: a new approach
BACKGROUND: Effective pain control in Dentistry may be achieved by local anesthetic techniques. The success of the anesthetic technique in mandibular structures depends on the proximity of the needle tip to the mandibular foramen at the moment of anesthetic injection into the pterygomandibular region. Two techniques are available to reach the inferior alveol
