MAXILLARY SECOND MOLAR

An unusual dilacerated root of a second maxillary molar.

An unusual case of a second maxillary molar with a dilacerated root visible clinically is described. Apicectomy followed by retrograde amalgam filling was performed whereby gingival coverage and gingival seal was achieved.

Maxillary canine‒second molar transposition: A rare case report

Tooth transposition, which is a rare condition, is ascribed to the disturbance of tooth eruption and the subsequent abnormal occlusal relationships. Transpositions mostly involve the upper jaw and more frequently occur between the maxillary canine and first premolar. Herein, we present a case of a maxillary canine‒second molar transposition in a thalassemic patient.

Treatment of a second maxillary molar with six canals.

Variations in the dental anatomy are found in all teeth. Knowledge of these variations, particularly concerning the location and treatment of all canals, is very important for the success of the endodontic therapy. The purpose of this study is to present a clinical case of a maxillary second molar with three palatal canals, two mesio-buccal and one disto-buccal canal. This report serves to remi...

Comparison of the crown dimensions between the maxillary second deciduous molar and the first permanent molar.

The morphologic relationship of the crown structures of the maxillary second deciduous molar (m2) and the first permanent molar (M1) was investigated with odontometric methods. Materials used were 124 male dental casts taken from Chinese living in Kaohsiung (Taiwan). The mesiodistal and buccolingual diameters, cusp sizes, and intercusp distances were measured. The mean crown diameters were larg...

Slow and continuous maxillary expansion, molar rotation, and molar distalization.
