External inflammatory and replacement resorption are mainly caused when avulsed teeth are replanted following traumatic dental injury. Resorption may ultimately lead to loss of tooth. This situation is mainly common in young and adolescents but may affect elderly also. Loss of tooth might lead to psychological depression of a young patient. Prosthodontic rehabilitation should focus on immediate...

BACKGROUND Socket preservation after tooth extraction is one of the indications of bone grafting to enhance preorthodontic condition. The aim of this study is to determine the effects of socket preservation on the immediate tooth movement, alveolar ridge height preservation and orthodontic root resorption. MATERIALS AND METHODS In a split-mouth technique, twelve sites in three dogs were inves...

OBJECTIVE To investigate the effect of age on root resorption and distribution along different parts of the root during prolonged light force application. MATERIAL AND METHODS Orthodontic appliances were placed in two groups of 30 rats (one group 6 weeks old, the other 9-12 months old), with contralateral sides as controls. Groups of animals were killed at 1, 2, 4, 8, and 12 weeks. At the stu...

background: antidepressant drugs such as fl uoxetine are of the most commonly used drugs among the public. these drugs may impact the regulation of bone cell functioning, and thus affect orthodontic tooth movement. the aim of this study was to determine the effect of fl uoxetine on tooth movements during orthodontic treatment in rats. materials and methods: in this study, 30 male rats were rand...

Prostaglandins are a group of chemical messengers that carry out a number of functions in the human body. One of their important functions is to enhance bone resorption. This may have a profound meaning for orthodontics, as the process of tooth movement is based on selective bone resorption and deposition around the teeth. This article reviews the literature concerning the discovery of prostagl...

Invasive cervical resorption (ICR) is a type of external resorption that is not well understood or well known in the dental community. It is often misdiagnosed, leading to improper treatment or unnecessary loss of the tooth. Treatment may involve the periodontium as well as the tooth and pulp, and management can be complex. Early diagnosis and appropriate treatment are the keys to a successful ...

AIM OF THE STUDY Chemotherapeutic treatment in children and adolescents carries a risk of congenital tooth disorders and dentinoma. Study objective is to assess the correlation between tooth abnormalities, early complications of multidrug chemotherapy, and chemotherapeutics used in different antineoplastic therapies in children and adolescents. MATERIAL AND METHODS Enamel defects (development...

Idiopathic root resorption is a very rare phenomenon. Resorption in tooth is brought about by odontoclastic activity. Special mechanisms in the periodontal ligament exist to prevent mineralization of the periodontal ligament and these periodontal ligament cells produce factors that inhibit mineralized tissue resorption and are capable of regulating bone and cementum formation. When this mechani...
