Odontoclastic root resorption is a significant clinical issue in relation to orthodontic tooth movement, and resorption of the roots of primary teeth is an intriguing biological phenomenon. The functional coordination of the OPG/RANKL/RANK system seems to contribute not only to alveolar remodeling, but also to resorption during orthodontic tooth movement and physiological root resorption. Serum...

Crown resorption of unerupted teeth in children has been reported in the dental literature (1). Such resorption may be similar to tooth resorption in adult teeth that have been embedded for long periods of time (2), but should be differentiated from external tooth resorption following trauma, infection, or excessive mechanical forces (3) and from internal tooth resorption originating from the d...

INTRODUCTION The effect of zoledronic acid, a potent and novel bisphosphonate, on tooth movement and orthodontically induced root resorption in osteoporotic animals systemically treated with zoledronic acid as similarly used in postmenopausal patients has not been elucidated. Therefore, this study was undertaken. METHODS Fifteen 10-week-old female Wistar rats were divided into 3 groups: ovari...

This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second premolar tooth. The clinical and radiographical evaluation revealed an external apical resorption in the mesial root of the maxillary first mo...

tramadol is a synthetic analgesic of opioids which has more flexible mechanisms of action than typical opioids. since it has been reported in previous study that typical opioids like morphine can affect the bone homeostasis, it is worthwhile to examine the effects of tramadol on tooth movement. in this study we investigated effects of tramadol on orthodontic tooth movement in rats.30 male wista...

Root resorption is the destructive process of the cementum and/or dentine layers of a tooth root due to clastic cell activity which leads to a subsequent loss root structure of a tooth. This process may be physiological or pathological. Physiological root resorption of deciduous teeth naturally occurs when the permanent teeth begin to erupt. It may also occur to a small degree in the permanent ...

When a tooth is avulsed and replanted following traumatic dental injury, complications such as replacement and inflammatory resorption may occur. Ultimately, resorption may result in loss of the tooth. This case report describes a traumatic injury to a permanent tooth resulting in complete root resorption within a short period, which required surgery. In the present case, improper treatment mea...

external root resorption of permanent teeth is a multifactorial process. several etiologic and predisposing factors have been related to external root resorption. idiopathic external root resorption is defined as cases of external root resorption without a distinct etiologic factor. this article presents an extensive idiopathic external root resorption of maxillary first molar with irreversible...
