Tooth trauma continues to be a common problem that every dental surgeon must be prepared to assess and treat when necessary. One of the serious traumatic injuries is avulsion where one or more teeth come out of the alveolar socket. Tooth avulsion is an emergency for children and adolescents requires management approaches for the survival of avulsed teeth. The objective of this article is aimed ...

INTRODUCTION Since the beginning of miniscrews as orthodontic anchorage, many applications have been described in the literature. Among these, one is the uprighting of mesially inclined molars. In regard to the mechanical aspects, however, there is little information about the application of orthodontic forces using such devices. OBJECTIVE The objective of this study was to describe a miniscr...

Key Points  Functional orthodontic techniques have been used to correct dentofacial deformities such as parrot mouth in the young horse.  An understanding of the orthodontic principles of tooth movement and the effects of forces on bone growth will insure the best surgical outcome.  The combined approach with retention wires of the upper jaw combined with a fixed acrylic and aluminum incline...

PURPOSE The purpose of the present study was to compare artificial tooth-brushing models (TBM) and individual modeling regarding their efficacy in teaching the correct brushing movements to younger preschool children. METHODS A total of 141 30- to 50-month-old preschool children who had not been previously instructed on tooth-brushing were enrolled in the present trial. Four different model ...

The presence of a supernumerary tooth in the nose is an unusual phenomenon and a rare form of ectopic tooth eruption in the maxillofacial region. In this case, the patient was referred to the hospital with the complaint of severe headache. In the endoscopic examination, the supernumerary tooth crown was not covered with mucosa or granulation tissue. In the present study, the clinical and radiol...

INTRODUCTION Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. OBJECTIVE The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate...

The restoration of endodontic tooth is always a challenge for the clinician, not only due to excessive loss of tooth structure but also invasion of the biological width due to large decayed lesions. In this paper, the 7 most common clinical scenarios in molars with class II lesions ever deeper were examined. This includes both the type of restoration (direct or indirect) and the management of t...

INTRODUCTION The aim of this study is to evaluate the effects of low-level neodymium-doped yttrium aluminium garnet (Nd:YAG) laser irradiation on orthodontic tooth movement and histological examination. METHODS Eleven male Wistar rats (aged 10 weeks) were included. To produce experimental tooth movement in rats, 10 g force was applied to maxillary first molars with nickel titanium closed coil...

Tooth movement is a biological process of bone remodeling induced by mechanical force. Sclerostin secreted by osteocytes is mechanosensory and important in bone remodeling. However, little is known regarding the role of sclerostin in tooth movement. In this study, models of experimental tooth movement were established in rats and mice. Sclerostin expression was investigated with immunohistochem...

The purpose of this study was to assess the effects of the administration of zoledronic acid (ZA) during orthodontic movement in rats. A hundred and twenty male Wistar rats were applied force of 30 cN with spring closed nickel-titanium to move the upper right first molar to mesial. In the Control Movement group (CM), only tooth movement was performed; the Control Acid Zoledronic group (CAZ) rec...
