External inflammatory root resorption (EIR) represents a challenge in endodontic practice. EIR commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  Treatment of EIR is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. Dental tra...

OBJECTIVES The purpose of the present study was to investigate the reliability of both periapical radiographs and orthopantomograms for exact detection of tooth root protrusion in the maxillary sinus by correlating the results with cone beam computed tomography. MATERIAL AND METHODS A database of 1400 patients scanned with cone beam computed tomography (CBCT) was searched for matching periapi...

AIM This finite element study was conducted to calculate the distribution of stresses in the periodontal ligament when various orthodontic forces were applied, with emphasis on the effect on root apex. MATERIALS AND METHODS An in vitro finite element method was used to construct a three-dimensional finite element model of a maxillary central incisor, its periodontal ligament and alveolar bone...

avulsion is a serious injury which causes damage to dental and supportive tissues, ranging from 1-16 % among dental injuries and it mostly occurs in maxillary incisors. this report presents a case of replantation of a traumatically avulsed central incisor. the left central incisor of an 8 year-old boy with open apex was avulsed and was left in unclean and dry conditions. tooth was replaced afte...

Dens invaginatus is a developmental anomaly resulting from epithelial invagination of the tooth crown before calcification. Endodontic treatment of teeth affected by dens invaginatusmay be difficult and complex due to aberrant anatomy. Combined orthograde and surgical approaches for successful treatment of dens invaginatus are effective. This report describes the successful treatmentand results...

Corresponding Author : Dr. Rekha Sharma Department of Orthodontics PDM Dental College & Research Institute Bahadurgarh-124507, Haryana (India) Apical root resorption is a common idiopathic problem associated with orthodontic treatment that results in permanent loss of tooth structure from the root apex. It has recently received considerable attention because of medico-legal exposure. Root resor...

PURPOSE This study aimed to investigate the clinical anatomy of lower premolar roots in a Spanish population by using cone-beam computed tomography (CBCT), correlating findings with patient gender and tooth type. MATERIALS AND METHODS Using 70 CBCT images, we evaluated 126 healthy, untreated, well-developed lower premolars. The number and morphology of roots and root canals, and the foramina ...

We report a case of oral malodor associated with internal resorption. A 39-year-old male attended our hospital complaining of oral malodor. Utilizing organoleptic measurement, the halimeter test and gas chromatography, it was diagnosed as a strong halitosis caused by oral origin. The pocket probing depth of tooth 21 was 10 mm, and X-ray examination revealed a vertical bone loss around this toot...
