Material and methods
The records were obtained from the Child Research Council in Denver, Colorado, and included longitudinal data from annual lateral cephalometric radiographs. All subjects were white and had not received orthodontic treatment. Selection of the open bite sample was based on a negative deciduous incisor overbite when measured to the occlusal plane at the age of 5 years. Fourteen subjects with negative overbites were chosen. The open bite was slight to moderate with a mean overbite of −0.7 mm (range

Discussion
The deciduous dentition open bite sample in the present study was characterized by a slight-to-moderate negative overbite. Although no habits had been noted, because of the young ages of the subjects, digit sucking or other habits cannot be ruled out. Longitudinal studies on dental casts for overbite change during the deciduous dentition have been conducted by Moorrees12 and Eismann and Reichert.13 Both studies showed that the amount of overbite in the permanent dentition is not closely related
Conclusions
- 1.
Thirteen of 14 subjects with an anterior open bite at age 5 years were characterized by a positive overbite when followed longitudinally until age 12. However, the overbite at 12 years was lower when compared with the control group.
- 2.
Early cephalometric characteristics of the deciduous dentition open bite included lower measurements for the overbite depth indicator and the ANB angle. During the longitudinal follow-up, the deciduous dentition open bite sample was also characterized by shorter

Malocclusion among children in Vietnam: Prevalence and associations with different habits
2024, Journal of Oral Biology and Craniofacial ResearchThe prevalence of malocclusion is higher in schoolchildren with signs of hyperactivity
2021, American Journal of Orthodontics and Dentofacial OrthopedicsCitation Excerpt :The prevalence of malocclusion was lower among children in the highest age group (11-12 years). Occlusal changes and the growth and development of the jaws enable the self-correction of some types of malocclusion.27-30 A longitudinal study showed that the prevalence of malocclusion was significantly reduced (70%-58%) from the deciduous dentition to the mixed dentition phase.30
Perinatal health and malocclusions in preschool children: Findings from a cohort of adolescent mothers in Southern Brazil
2017, American Journal of Orthodontics and Dentofacial OrthopedicsCitation Excerpt :Additionally, a birth cohort study showed that the occurrence of open bite, crossbite, and canine malocclusion in the deciduous dentition is predictive for malocclusion in the permanent dentition.22 Whereas there is evidence that anterior open bite tends to disappear with the early discontinuation of sucking habits, the same is not true for posterior crossbite and overjet.37,38 Thus, dentists should provide anticipatory guidance for parents to support extended breastfeeding and to help children stop sucking habits,39 and regularly monitor children with malocclusion at a young age22 to assess self-correction or the maintenance of occlusal alterations.
Mathematical modeling for explanation and prediction of treatment outcome in growing patients with anterior open bite malocclusion treated with rapid molar intruder and posterior bite blocks
2017, Orthodontic WavesCitation Excerpt :In the current study, the multivariate model was able to identify the morphological components that significantly contributed to overbite increase after treatment with RMI and PBBs over 4 months. Previous studies reported that untreated AOB with hyperdivergent face is unlikely to be self-corrected and the facial growth is most likely to continue with same direction [12–14]. Facial axis angle is an important reference for growth direction [15].
