Background The use of CBCT exam in the study of IMC is not new. However, it's still not known in what specific aspects CBCT exam shows a better result than then conventional exams. The aim of this study was to compare and conclude in what way the opinion regarding upper canine impaction differed when observing a panoramic image compared to the observation of a set of CBCT reconstructions. Mat...

Permanent central incisor impaction is very rare, and causes of include adjacent supernumerary teeth, odontoma, trauma. Surgical repositioning a treatment option for teeth with ectopic eruption pathways. In this case report, an inverted developing maxillary was surgically repositioned at the initial stage root development. Three dimensional (3D) virtual images were acquired using computed tomog...

Background: Impacted tooth is common in dental practice. Dentists usually remove them if they are associated with any pathologic sign or symptom. The challenge is whether to extract the asymptomatic tooth or not. This study was conducted to determine the association between developmental odontogenic cysts and tumors and impacted and unerupted teeth, if left untreated.    Methods: In ...

OBJECTIVE The aim of this study was to identify the prevalence of pathological changes in the pericoronal tissue of asymptomatic impacted lower third molars and to assess the correlation between pathological changes and patient demographic, radiographic and morphological characteristics. STUDY DESIGN Follicles associated with fully impacted lower third molars were submitted for histological e...

Impaction of an anterior primary tooth is rare, and most often is associated with the presence of a supernumerary tooth or odontoma (Axel 1937; Amies 1947; Amies 1952; Hitchin and White 1955; Hitchin 1962; Hitchin and Dekonor 1963; Noonan 1971). Although cases of impacted mandibular and maxillary incisors have been reported (Troxler 1973; Yokoyama 1973), most cases involve the maxillary canine ...

Traumatic injury to a primary tooth and/or a bone fracture has the potential to damage the underlying permanent tooth germ which may disturb its development. The extent of the malformation depends on the developmental stage of the permanent tooth and the intensity of the trauma. The presence of infection may be a predictive factor for these abnormalities. Open surgical procedures can also poten...
