Due to the speculation of third molar role on late incisor crowding, many orthodontists prescribe remov...

The mandibular second premolar is usually described as a single rooted tooth with a single root canal. However, two root canals may be found but the occurrence of two roots is extremely rare. The reported studies have shown 0.3% prevalence of two roots in mandibular second premolars. This report describes an unusual case of a thirteen year old female patient with bilateral two rooted mandibular...

OBJECTIVE The aim of this study was to determine whether or not lingual arches in subjects with anterior or posterior mandible rotation can produce different effects in the prevention of first permanent molar mesial migration. SUBJECTS AND METHODS Forty-two patients with a mean age of 9 ± 0.8 years were selected from the Department of Orthodontics, University of Catania, Italy. These subjects...

One of the rare anatomical variations that can be of significant importance for the dentist is the bifid mandibular canal. Many complications can occur from this condition such as failure of anesthesia when performing inferior alveolar nerve block, difficulties during the surgical extraction of the third mandibular molar, and during implants placement. Therefore, good knowledge of this conditio...

Mandibular molars demonstrate considerable variations with respect to number of roots and root canals. The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy. This paper discusses the endodontic management of the rare anatomical complexity middle mesial canals in mandibular first molar and also serves to remind the clinic...
