introduction: nasal teeth eruption is a rare phenomenon. the variability of symptoms and generic history makes the diagnosis difficult. this difficulty is more challenging when the tooth is placed in the depth of septum.   case report: our case is an example of this problem. herein, we present a case of intraseptal tooth with nasal obstruction and septal deviation and recurrent sinusitis. we pr...

Premolars rank third in frequency after third molars and maxillary canines in impacted or unerupted teeth. Failure to detect and analyze the problem may lead to unnecessary space loss, crowding, or collapse of the dental arch. A diagnostic scheme is presented to facilitate diagnosing and treating unerupted premolars. Important observations include: Diagnosing congenitally missing permanent teet...

BACKGROUND To evaluate disturbances in primary tooth eruption and their management with nonpharmacological remedies. METHODS In this nonrandomized clinical trial, 270 children aged between 8 and 36 months were selected and divided into 5 groups with 54 children initially enrolled in each group. The children were seen during an 8-day period during tooth eruption. At each appointment data were ...

Failure of eruption of primary teeth can be considered rare, especially in maxillary anterior teeth. The problem can be either mechanical obstruction of eruption or a failure of the eruption mechanism. This case report presents failure of eruption of the maxillary right deciduous central incisor in a 4-year-old girl. The unerupted primary tooth was removed surgically. The histological finding r...

Intrusive luxation is a serious dental injury that causes damage to the pulp and supporting structures of a tooth because of its dislocation into the alveolar process. This paper presents the case of the re-eruption of a severely intruded immature permanent incisor with a crown-root fracture. A 9-year-old boy was referred to the clinic 1 day after a fall. Clinical and radiographic examinations ...

Cleidocranial dysplasia (CCD), a skeletal disorder characterized by delayed permanent tooth eruption and other dental abnormalities, is caused by heterozygous RUNX2 mutations. As an osteoblast-specific transcription factor, RUNX2 plays a role in bone remodeling, tooth formation and tooth eruption. To investigate the crosstalk between RUNX2 and 1α,25-dihydroxyvitamin D3 (1α,25-(OH)2D3) in human ...

The aim of this study was to document variation of deciduous tooth formation and eruption. The material comprises 121 individuals of known or estimated age (using tooth length) from Spitalfields in London, and radiographs of 61 healthy living children aged 2-5 years. Other skeletal material from two medieval Scottish archaeological sites (Whithorn, N=74; Newark Bay, N=59) was also examined. Sta...

background: to determine the mean eruption time of permanent teeth of pakistani children and to evaluate the effects of gender, type of schools, height, weight and body mass index on it. methods: this cross sectional study was conducted from september 2007 to april 2008.  4370 children of ‘just erupted' teeth were obtained from 102 randomly selected schools from 18 towns of karachi, using syste...

INTRODUCTION Failure of teeth to erupt from gingival tissues at usual developmental time is called delayed tooth eruption (DTE). Delayed tooth eruption lead to prolonged fixed orthodontic treatment and its eventual complications. The purpose of the present study was to evaluate the effect of laser-assisted (808 nm) surgical uncovering, on the tooth emergence and orthodontic treatment of DTE. ...

an impacted tooth can be performed with either fixed or removable appliances. Fixed appliances do not require special patient cooperation and can produce precise coronal and root movements.1,2 On the other hand, the wire attached to the impacted tooth may be more easily deflected than with removable appliances, causing undesirable movements of adjacent teeth.3 Such movements are minimized with ...
