Hopeless retained deciduous teeth without permanent successors pose a restorative challenge for clinicians as well as certain clinical problems for patients. Compromised aesthetics, shifting of adjacent teeth, altered occlusion, and supereruption of teeth are examples of problems that can arise when a permanent tooth is congenitally missing. Mattheeuws, et al1 reported that the mandibular secon...

BACKGROUND The objective of this study was to examine the association between low blood lead levels of <5 μg/dL and the development of dental caries among children. METHODS The Children's Health and Environment Research (CHEER) group recruited a cohort of 7,059 school-aged children from six Korean cities. The final study populations in the permanent and deciduous teeth groups were 1,564 and 1...

Patients with cleidocranial dysplasia (CCD) commonly present with significant dental problems, such as retention of multiple deciduous teeth, impaction or delay in eruption of permanent teeth and, often, the presence of supernumerary teeth. Several approaches have been described for the management of such patients. We report 2 cases illustrating the shift in the management paradigm from edentul...

As shown in 62 pairs of dental opponents from 32 grossly normal human fetuses in the 75-378 mm crown-rump range, mandibular precedence is the rule for 11, 12, C and M1, a trend in agreement with mandibular precedence for deciduous teeth through dm1 and in the gingival emergence of the same permanent teeth during postnatal development.

The ectopic development of teeth has been reported in many locations including the nasal cavity, maxillary sinus and the chin. Ectopic teeth may be permanent, deciduous or supernumerary. A case is presented in which a supernumerary tooth erupted into the maxillary sinus of an 11 year old boy.

Human periodontal ligament from resorbing deciduous teeth demonstrated collagenolytic activity when incubated on collagen gels. This activity was directly proportional to the size of the explant and length of time of incubation. No activity was observed in ligaments obtained from completely formed premolar teeth.

Introduction: In restorative dentistry, selecting the proper material is an important factor for clinical success. The objective of this study was clinical evaluation of survival time of three tooth color materials in primary anterior teeth. Methods: In this interventional clinical trial study, 94 deciduous anterior teeth (36 teeth in boys, 58 teeth in girls) belonging to 3-5 year old children ...
