background & aim: regional odonto dysplasia (rod) is an unusual nonhereditary of teeth with significantly clinical and radiographic features. affected teeth usually remain unerupted or semi-erupted with a discolaration and irregular shape. radiographically these teeth have a large pulp chamber and thin layer of enamel and dentin with similar density. this article is introducing a female patient...

Supernumerary teeth are the teeth present in addition to the normal set of teeth. They may be single, multiple, unilateral or bilateral, erupted or unerupted and in one or both jaws. Multiple supernumerary teeth are rare in individuals with no other associated diseases or syndromes. Our case presents with four supernumerary premolars, asymptomatic, of which one was erupted and three were unerup...

BACKGROUND Mutans streptococci (MS) are closely related to the development of dental caries and are usually established in the oral cavity during early childhood. The aim of the study was to identify factors associated with the presence of MS in Swedish 1-year-olds. METHODS Parents completed a questionnaire on different caries-associated factors and an oral bacterial sample was collected from...

We discuss various models and scenaria proposed to explain the nature of the V838 Mon type eruptions. To this class of eruptive objects we include: M31 RV (erupted in 1988), V4332 Sgr (erupted in 1994) and V838 Mon (erupted in 2002). We concentrate on three models: (i) thermonuclear runaway on an accreting white dwarf (nova-like event); (ii) He-shell flash in a post asymptotic giant branch star...

Orthodontic alignment of un-erupted dilacerated teeth is challenging, as the bent roots resist forces applied to move them through the bone. Various treatment options are now available to treat this condition including providing prosthesis after extractions and apicectomies. However, to maintain alveolar bone in the area of the un-erupted tooth, especially if the involved tooth is in the anteri...

Introduction: Odontomas are the most common odontogenic tumors of the jaws which are benign, slow growing and nonaggressive. They are usually asymptomatic and are diagnosed on routine radiological examination. The eruptions of odontomas are uncommon and very few cases are reported in the literature. Objective: To report two rare cases of erupted compound odontomas. Case report: Two cases of eru...

Abstract Background the position and angulation of mandibular third molars have both been found to influence angle condylar fractures. Objective: To identify whether there is an association between depth molar impaction relative risk fracture condyle. Method Four-hundred eighty-two panoramic dental radiographs were assessed for period from January 2012 June 2020. The study variables included pr...
