Typically developing writers in fifth (n = 110, M = 10 years 8 months) or seventh (n = 97, M = 12 years 7 months) grade wrote informative, compare and contrast, and persuasive essays for which the content was held constant-two mountains with a history of volcanic eruption. Relevant background knowledge was provided by reading text and showing colorful illustrations to the students before writin...

Ectopic eruption is a developmental disturbance in which the tooth fails to follow its normal eruption pathway. Ectopic eruption of the second molar is relatively rare. This paper presents the case of thirteen-year-old male with an ectopic mandibular second permanent molar. The condition was corrected with surgical exposure and placement of elastic separators. This case report lays emphasis on ...

I . Numbers of erupted primary teeth were counted in young children in four rural villages in The Gambia. The ages of all children were precisely known, and their heights and weights were measured. 2. The majority of children were recorded as having an even number of teeth. The number of primary teeth present in children of given age varied widely. Up to 18 months of age, the Gambian children l...

Delayed eruption of a single primary tooth is an uncommon event. Excluding a previous traumatic insult, the presence of a pericoronal odontogenic cyst or neoplasm is the primary cause for this abnormality. This case report describes the clinical and radiographic features of an ameloblastic fibro-odontoma in a young child, who presented with delayed eruption of the primary mandibular canine and ...

Abnormalities of dental development and eruption occur quite commonly in the horse and result in a wide range of clinical conditions. A congenital/developmental problem present at the time of tooth eruption often leads to acquired dental problems as the teeth continue to erupt and wear. Consequently, several different dental abnormalities whose pathogenesis may be inter-related, are often prese...

The purpose of these case reports is to introduce an innovative orthodontic appliance to effect forced eruption. This device is useful when attempting to erupt teeth in the esthetic zone with minimal effect on adjacent teeth. It is especially indicated for adjacent teeth with esthetic restorations. The appliance is easy to fabricate, cost-effective and very useful in forced eruption efforts for...

fusion is an anomaly manifested in both deciduous and permanent dentitions. fu- sion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. triple tooth refers to the :union: of three separate tooth entities. it can occur by fusion, germination,...

Dentigerous cyst is a common pathologic entity associated with an impacted tooth. The standard treatment for this lesion is enucleation and extraction of the involved tooth. Marsupialization of dentigerous cyst has also been advocated, once in many cases it can maintain the impacted tooth in its cavity and promotes its eruption. This report describes a case of a 13-year-old girl with a large de...

INTRODUCTION Odontomas are benign odontogenic tumors composed of enamel, dentine, cement and pulp tissue. They are usually clinically asymptomatic, but often associated with tooth eruption disturbances. In exceptional cases the odontoma erupts into the mouth . The present study reports three cases of odontomas erupted into the oral cavity and reviews the literature. CLINICAL CASES The first c...
