Introduction: Root resorption, generally expressed in a round apical shape, is one of the most common findings in the orthodontic clinic. Objective: To radiographically evaluate whether vital and endodontically treated teeth present similar severity of apical root resorption in response to orthodontic treatment. Methods: This study was conducted with twenty-eight patients who had one upper cent...

severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...

The purpose of this study was to clarify the prevalence and degree of root resorption induced by orthodontic treatment in association with treatment factors. The files of 243 patients (72 males and 171 females) aged 9-51 years were randomly selected from subjects treated with multi-bracket appliances. The severity of root resorption was classified into five categories on radiographs taken befor...

The response of the dentoalveolar apparatus to infection is characterized by inflammation which may result in tooth resorption. Depending upon the type of resorption and etiology, different treatment regimens have been proposed. The following two cases demonstrate internal and external inflammatory root resorption arrest by conventional nonsurgical endodontic therapy combined with calcium hydro...

OBJECTIVE To test the hypothesis that the administration of aspirin, acetaminophen, meloxicam, celecoxib, and prednisolone have no effect on root resorption and tooth movement. MATERIALS AND METHODS A mesial force of 50 g was applied to the left maxillary first molars of sixty 10-week-old male Wistar rats using nickel titanium closed coil springs attached to the cervical area of the incisors....

Aim: Previous studies have demonstrated that orthodontic forces may injure dental pulp tissue via the apical foramen. The purpose of this study was to investigate the expression of various cytokines in pulp tissues of root apex after orthodontic tooth movement and compare the amount of internal root resorption in vital and pulp less rat teeth. Methods: Upper right first molars of 7-week Wistar ...

Root resorption is an unwanted effect of orthodontic tooth movement. Analysis of dentine proteins in gingival crevicular fluid (GCF) is a potentially safer method of quantifying root resorption compared with conventional radiographic methods. This study aimed to identify and quantify the dentine-specific matrix protein, dentine sialoprotein (DSP), released into GCF during physiological root res...

STATEMENT OF THE PROBLEM Root resorption (RR) after orthodontic tooth movement (OTM) is known as a multifactorial complication of orthodontic treatments. Hormonal deficiencies and their effect on bone turnover are reported to have influences on the rate of tooth movement and root resorption. PURPOSE This study was designed to evaluate the effect of female and male steroid sex hormones on toot...

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...

OBJECTIVE Molar intrusion by mini-screw implantation can cause different degrees of root resorption. However, most methods (2-D and 3-D) used for evaluating root resorption have focused on the root length without considering 3-D resorption. The purpose of this study was to volumetrically evaluate root resorption using cone beam computed tomography(CBCT) after mini-screw implant intrusion. MAT...
