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 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...

The orthodontic treatment of patients with pre-existing root resorption (RR) is often difficult due to the increased risk progression and a compromised outcome can be expected. plan in such situations should comprise sparing strategy, which includes reducing duration fixed appliances, non-extraction treatment, force levels, avoiding intrusion at-risk teeth, amount apical movement affected teeth...

AIM To evaluate ex vivo the accuracy of two electronic apex locators during root canal length determination in primary incisor and molar teeth with different stages of physiological root resorption. METHODOLOGY One calibrated examiner determined the root canal length in 17 primary incisors and 16 primary molars (total of 57 root canals) with different stages of root resorption based on the ac...

Introduction: Internal root resorption is a progressive loss of dentin in teeth with inflamed and possibly partially necrotic pulp tissue. If diagnosed at early stages, the process is halted by endodontic treatment. While endodontic treatment is the preferred treatment modality for internal root resorption, current standard endodontic techniques pose a challenge for cleaning, disinfection and o...

Referred patient 14 years old (in orthodontic treatment) for a suspected resorption on 2.1 that was exposed to trauma [1]. After an apical x ray, cone beam performed have complete diagnosis [2,3]. Almost the 80% of root is resorbed, after achieving parents’ consent treatment, planned intentional replantation [4] and retrograde approach. In case like this treatment’s goal stop resorption, removi...

BACKGROUND Diagnosis of external root resorption (ERR) cavities may be challenging, especially when no clinical signs are seen. Therefore, the aim of this study was to compare the efficacy of conventional intraoral film radiography, charge-coupled device (CCD) detector, photostimulable phosphor plate (PSP) detector, and cone beam computed tomography (CBCT) for the detection of ERR. METHODS Th...

The purpose of the current study was to evaluate noise reduction effect on apical root resorption evaluation in digital radiography. In the present experimental study, 60 extracted lower premolars with sound roots were used. The teeth were fixed in a dry human mandible for radiographic evaluation. Digital radiographs were taken before and after artificial external root resorption on the mesial ...

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 ...

This study aims to critically evaluate orthodontically induced external apical root resorption (OIEARR) in incisors of patients undergoing non-surgical orthodontic treatment of class II division 1 malocclusion by a systematic review of the published data. An electronic search of two databases was performed; the bibliographies of relevant articles were also reviewed. Studies were included if the...
