external root resorption may be an uncontrolled phenomenon, and the most known interventions have no effect. even progressive external root resorption may not be controlled by long term ca(oh)2 therapy. currently, there are no treatment options for vital tooth that suffer from root resorption. this invasive resorption can lead to extraction of the tooth. the use of new technologies such as low ...

objective(s): to determine the effect of different doses of caffeine on orthodontic tooth movement (otm) in rats. materials and methods: forty male 250-300 g sprague-dawley rats were randomly divided into four groups of ten animals each and received 0 (control), 1 g/l, 2 g/l and 3 g/l caffeine in tap water for 3 days. orthodontic appliances were ligated between the maxillary first molars and in...

Management of internal root resorption is a challenge to the endodontists. If it is left untreated, it may lead to the destruction of the surrounding dental hard tissues. Despite, routine obturation techniques are often employed without considering the best technique to solve this problem. This study presented a case of internal root resorption and apical periodontitis affecting tooth 12 (FDI) ...

Introduction In addition to periodontal disease and chronic gingivostomatitis, tooth resorption (previously termed feline odontoclastic resorptive lesions, FORL) are among the most common and frustrating diagnostic findings in feline dentistry. Reported prevalence rates of tooth resorption range from about 30 to 70 %, depending on the composition of the population examined and on the diagnostic...

objective: osteopontin (opn) has been proposed to play a role in bone resorption. with regard to bone and cementum/dentin structural and histological similarities, it was hy-pothesized that expression of this gene might be increased in resorptive lacunae during orthodontic tooth movement. materials and methods: fixed nickel-titanium closed coil springs (dentaurum ® ) capa-ble of delivering appr...

this paper reports multidisciplinary treatment of a dental trauma case to achieve a favorable prognosis. a healthy 14-year-old girl reported avulsion of teeth 11 and 21 which had occurred three months earlier. the initial treatment consisting of replantation with a semi-rigid splint was performed in hospital. at presentation, the patient was still using the semi-rigid splint. the clinical exami...

introduction: tooth avulsion is a real dental emergency. if immediate replantation is not performed, the avulsed tooth may be lost due to inflammatory or replacement resorption. this animal study aimed to evaluate the bone response to the titanium coating of the root surface as an artificial barrier, and prevention of resorption of avulsed teeth. methods and materials: this experimental study w...
