The present study investigated the influence of archwire size and ligation method on the force magnitude delivered by nickel-titanium alloy archwires to 4 incisor brackets (42, 41, 31, and 32) in a simulation of mandibular right lateral incisor linguoversion. The force delivered by 0.014 and 0.016 inch nickel-titanium alloy archwires was measured using a newly developed multi-sensor measuring s...

Abstract This case report describes successful long-term conservative management of a cervical root fracture and a complicated crown fracture of the maxillary central incisors in a 12-year-old patient. A mineral trioxide aggregate partial pulpotomy was performed on the maxillary right central incisor, while the maxillary left central incisor was splinted to the neighbouring lateral incisor usin...

nine is the most frequently impacted tooth in the dental arch. Although the incidence of canine impaction is about 1 in 100 in the general popula­ tion,1 the ratio tends to be much higher in an ortho­ dontic practice—perhaps as high as 23.5%, ac ­ cording to one researcher.2 Palatal impactions are more prevalent (85%) than labial impactions (15%).3­5 early detection of impactions is critical to...

BACKGROUND Considerable variations in the development stage among patients of the same chronological age have led to introduce the concept of the developmental age based on the maturation of different organs such as cervical vertebrae or teeth. OBJECTIVES The purpose of this study was to investigate the correlation between the stages of tooth calcification and the cervical vertebral maturatio...

A tooth displaced down into alveolar bone is an intrusive luxation. This injury usually is accompanied by comminution of alveolar fracture. The dislocation is frequently axial and radiographic examination reveals absence of periodontal space. The primary site for luxation injuries is the maxillary anterior region in the primary and permanent dentition with frequency higher in the primary dentit...
