Original works by W. D. Miller 1 in the late 1800s and early 1900s, seem to be the earliest review in English of the erosion-abrasion issue as it relates to tooth brushing and dentifrices. Miller discussed wasting away of the tooth at the neck as "very often taking a form as though produced by a three-cornered file (p. 2).” 1 Possible causes of wasting away mentioned in the literature at that t...

The Witkop syndrome is a rare autosomal dominant disorder characterized by the absence of several teeth and abnormalities of the nails. This is the first report of a rare genetic tooth and nail syndrome diagnosed in a 2.5-year-old boy with early exfoliation of the primary canine, absence of the primary incisors, and nail dysplasia. A homozygous mutation was identified in 3'-UTR of MSX1 gene in ...

J Korean Assoc Oral Maxillofac Surg 2012;38:177-83) Herpes zoster is a viral infection caused by the reactivation of the varicella zoster virus, an infection most commonly affecting the thoracolumbar trunk. Herpes Zoster Infection (HZI) may affect the cranial nerves, most frequently the trigeminal. HZI of the trigeminal nerve distribution network manifests as multiple, painful vesicular eruptio...

I read with interest Rabbani et al’s paper entitled “Dental problems in hypophosphatemic rickets, a cross sectional study” in the fourth issue of Iran J Pediatr 2012[1]. Clinical oral manifestations of hypophosphatemic rickets often include premature tooth exfoliation, hypoplastic enamel and dental infections. Apical rarefaction, rickety bone trabeculation and absent or abnormal lamina dura are...

Reptiles and fish have robust regenerative powers for tooth renewal. However, extant mammals can either renew their teeth one time (diphyodont dentition) or not at all (monophyodont dentition). Humans replace their milk teeth with permanent teeth and then lose their ability for tooth renewal. Here, we study tooth renewal in a crocodilian model, the American alligator, which has well-organized t...

Deciduous teeth exfoliate as a result of apoptosis induced by cementoblasts, a process that reveals the mineralized portion of the root while attracting clasts. Root resorption in deciduous teeth is slow due to lack of mediators necessary to speed it up; however, it accelerates and spreads in one single direction whenever a permanent tooth pericoronal follicle, rich in epithelial growth factor ...

The preservation of deciduous teeth is essential until normal exfoliation. It plays an important role in preventive and interventional dentistry. Early loss a tooth or can have various consequences. Space maintainer the intra-alveolar kind advised when second molar lost before eruption first permanent molar. This report discusses modified Willet appliance cases where primary occur prior to mand...

In recent years a strategy of selective, symptom-based intervention of carious primary teeth has been developed amongst some British general dental practitioners. Practice-based studies appear to provide evidence that policies of restoration of symptomless carious primary teeth do not confer any significant benefits above those associated with non-restorative care. However, results from these s...

The goal of primary tooth pulp therapy is the preservation of the primary teeth until their normal time of exfoliation. Teeth with carious involvement approaching the pulp can be treated with a variety of approaches, including three pulpotomy techniques--diluted formocresol, ferric sulfate, and mineral trioxide aggregate--and an indirect pulp therapy technique. Accurate diagnosis of the vitalit...

AIM The aim of this report is to present a clinical case of impaction of a maxillary left central incisor in a mixed dentition caused by the presence of an odontoma as well as a review of the pertinent dental literature. BACKGROUND Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiolog...
