Child development from conception through the first years of life is marked by many changes. Tooth eruption follows a chronology corresponding to the date when the tooth erupts into the oral cavity. These dates have been established in the literature and are subjected to small variations depending on hereditary, endocrine and environmental features. At times, however, the chronology of tooth er...

The development of alveolar bone adjacent to the tooth root during tooth eruption is not well understood. This study tested the hypothesis that predominantly woven bone forms adjacent to tooth roots during tooth eruption, but that this immature structure transitions to lamellar bone when the tooth comes into function. Additionally, bone resorption was predicted to play a key role in transitioni...

the term odontoma is used to identify a tumor that is characterized by the production of mature enamel, dentin, cementum and pulp tissue and may interfere with the eruption of the associated tooth. the present report describes an odontoma in a 13-year-old boy, which is associated with an impacted tooth through a canal

REASONS FOR PERFORMING STUDY There are few published data to support the ages of emergence of permanent dentition widely reported in horses. OBJECTIVES To clarify the chronology and sequence of permanent premolar (PM) tooth emergence in Thoroughbred racehorses. METHODS A prospective study was undertaken in which records were kept of deciduous PM 'cap' extractions performed during routine de...

Age determination is an important tool in wildlife studies. Estimating the age of animals in the field using tooth wear criteria may be subject to error as a result of variations between individuals, habitats and populations. Data on age estimation of leopards and tooth wear characteristics are lacking. Nineteen leopards in Namibia were assessed for tooth eruption and wear. Between 1991 and 199...

BACKGROUND Traumatic injuries to primary teeth represent one of the most common aetiologic factors of time-related eruption disturbances of permanent teeth. These include premature eruption, delayed eruption or impactions. CASE REPORT A case of a 7.5-year-old male with delayed eruption of the maxillary permanent left incisor is presented. The case history revealed a trauma around the age of 3...

Ameloblastic fibrodentinoma (AFD) is a rare benign mixed odontogenic tumor that occurs predominantly in children and young adults. AFD is usually associated with delayed eruption of the tooth and shows painless swelling. We present a case of AFD affecting an 8-year-old Japanese girl with a complaint of delayed eruption of her left mandibular second premolar tooth. Intraoral examination did not ...

AIM The aims of this study were firstly to determine the fate of unerupted permanent maxillary incisor teeth following supernumerary tooth removal and secondly to make recommendations regarding the management of such incisor teeth following supernumerary tooth extraction. STUDY DESIGN This is a retrospective study. METHODS Records of children attending the Departments of Paediatric Dentistr...

Previous studies suggest that primary tooth eruption (PTE) in preterm infants is related primarily to gestational age, but the impact of other neonatal factors has not been studied. In a prospective longitudinal study, the timing and sequence of PTE were documented by a pictorial PTE record completed by the parents and by frequent oral exams in 14 preterm infants whose first tooth erupted at < ...
