Root resorption (RR) is one of the most common sequelae of orthodontic treatment. A key role for a genetic influence in external apical root resorption (EARR) was described recently, by describing both linkage and linkage disequilibrium between interleukin-1B (IL-1B) and EARR in orthodontically treated individuals, accounting for approximately 15% of the variation in EARR. The murine model, whi...

PURPOSE The purpose of this study was to examine the patient- and treatment-related etiologic factors of external root resorption. MATERIALS AND METHODS This study consisted of 163 patients who had completed orthodontic treatments and taken the pre- and post-treatment panoramic and lateral cephalometric radiographs. The length of tooth was measured from the tooth apex to the incisal edge or c...

The indications for impacted third molar extraction include the prevention of dental reabsorption on the adjacent tooth. Resorption can be classifi ed as physiological (when deciduous teeth are exfoliated) or pathological (when caused by injury or irritation to the periodontal ligament). Many causes can trigger external root resorption (ERR), the most common cause of which is orthodontic forces...

Inflammatory external root resorption (IERR) is a pathological phenomenon of microbial origin. This study reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (RCT). Radiographic investigation revealed periapical radiolucencies in the uppe...

The hypothesis of this study is that children with unexpected early apical resorption of the primary teeth are also predisposed to resorption in the permanent dentition. Accordingly, the aim was to perform a longitudinal study focussing on the permanent teeth in children with unexpected early apical resorption in the primary dentition. Panoramic radiographs of 12 children (7 boys and 5 girls) a...

The aim of this case report was to present management of a case of multiple apical root resorptions due to orthodontic treatment in a 27-year-old adult female using implant supported crowns. External root resorption of the permanent teeth is a multi-factorial process. Well recognized causes of apical root resorption in permanent teeth include orthodontic therapy, trauma, periapical or periodont...

When a tooth sustains a luxation injury, attachment damage of varying degrees will occur. In addition, necrosis of the pulp might result, thereby making the pulp space susceptible to infection. These circumstances can lead to root resorption. Treatment for root resorption includes preventing it by avoiding causes of root surface injury, minimizing initial inflammation, and reversing resorption.
