BACKGROUND Primary failure of eruption (PFE) is a rare disease defined as incomplete tooth eruption despite the presence of a clear eruption pathway. Orthodontic extrusion is not feasible in this case because it results in ankylosis of teeth. To the best of our knowledge, besides the study of Ahmad et al. (Eur J Orthod 28:535-540, 2006), no study has systematically analysed the clinical feature...

Primary failure of eruption represents a cessation of tooth eruption before emergence not due to a physical barrier or abnormal position and has no systemic cause. This failure of tooth eruption is rare phenomenon and it has not been associated with alterations of dental follicle. This case report describes a permanent right first molar with primary failure of eruption at the inferior border of...

One of the most reasonable hypotheses regarding the functional significance of the browridge is that the supraorbital torus forms in response to masticatory stress during development. Oyen, Walker, and Rice (1979) have recently proposed a model that tests this hypothesis: if browridges are functionally related to masticatory stresses on the cranial vault, then changes in the biomechanics of the...

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 p...

This article reviews the infrequently utilized treatment method of forced eruption and how it can serve as an alternative to the sacrifice of the natural root system. Forced eruption can preserve the natural root system and related periodontal architecture, resulting in years of additional service for the patient. It also can maintain adjacent tooth structure while retaining the option for futu...

The relationship between tooth eruption and otitis media has been a subject of debate in the literature. Teething may produce conditions conducive to the initiation or exacerbation of otitis media as well as other local and systemic clinical manifestations. A report of a child with bacterially involved pericoronitis associated with primary tooth eruption is presented. The potential relationship...

odontoma.2,3 Compound odontomas consist of tooth-like structures that radiographically appear as opacities. Complex odontomas comprise a mixture of odontogenic tissues without dental organization.2,4 Clinically, three types of odontomas are recognized in the literature: central (intraosseous) odontoma, peripheral (extraosseous or soft tissue) odontoma, and erupted odontoma.2,5 Odontomas are oft...

The impaction of lower second molars, given that its incidence is 0.03 to 0.21%, is a rare complication in tooth eruption. It has been detected more often in unilateral form than bilateral and is more common in the mandible than in the maxillary. It has a slight predilection for males, and mesial inclination is more usual. A wide variety of therapeutic approaches have been published, basically ...

T ooth eruption with little or no root development is rare and is usually associated with neonatal teeth or defects in root formation due to irradiation therapy of the head and neck. Possible causes of root absence are hereditary anomalies such as dentinal dysplasia, morphological anomalies known as dystrophies, and idiopathic root resorption. A tooth in a very early stage of root development c...
