AbstractAmong 234 children examined annually from age three to 20 years at the Burlington Growth Centre, there was statistically significant cooccurrence of early and late emergence sequences of the permanent first and second molars relative to the central incisors and second premolars in the same jaw and in both jaws.

Eruption of third molars: relationship to inclination of adjacent molars
American Journal of Orthodontics and Dentofacial Orthopedics, 2004The purpose of this study was to determine the relationship between the sagittal inclination of the first and second maxillary molars and the eruption of the third molars. The sample consisted of 2 groups. The subjects in the first group (n = 28) had complete normal dentitions including third molars; those in the second group (n = 32) had impacted ...

Molar and incisor changes with Wilson rapid molar distalization
American Journal of Orthodontics and Dentofacial Orthopedics, 1993The purpose of this study was to determine the magnitude and direction of maxillary and mandibular first molar and incisor changes that occur during Class II molar correction with Wilson "rapid molar distalization." Nineteen patients (13 females, 6 males) were selected from the clinic at Loma Linda University Department of Orthodontics.

Villous alpha-fetoprotein in molar and non-molar abortuses
Human Reproduction, 1987The alpha-fetoprotein (AFP) content of chorionic villi from elective and spontaneous abortuses, diploid androgenetic and paternally derived triploid conceptuses was measured by a radioimmunoassay technique and related to the presence of fetal parts and chromosome constitution.

Molar Masses and Molar Mass Distributions
1984In synthesizing polymers in vivo and in vitro, molecular homogenous (“monodisperse”) polymers (i.e., those in which every macromolecule has the same molar mass or “molecular weight”) occur only under quite specific conditions. The overwhelming majority of polymer syntheses proceed more or less randomly, and the resulting macromolecular substances have ...

Second molars can create great delays in orthodontic treatment if they are not managed intelligently. The purpose of this article was to describe common torque and position problems of the second molars and techniques for managing them. A simple technique for freeing mesially impacted second molars is presented.
