Cervical external root resorption.
External resorptions associated with inflammation in marginal tissues present a difficult clinical situation. Many times, lesions are misdiagnosed and confused with caries and internal resorptions. As a result inappropriate treatment is often initiated. This paper provides three-dimensional representations of cervical external resorption, based on X-ray microfocus-tomographical scanning of a ca...
متن کاملCollagenolytic activity of periodontal ligament during human deciduous root resorption.
Human periodontal ligament from resorbing deciduous teeth demonstrated collagenolytic activity when incubated on collagen gels. This activity was directly proportional to the size of the explant and length of time of incubation. No activity was observed in ligaments obtained from completely formed premolar teeth.
متن کاملOrthodontic external root resorption--endodontic considerations.
External root resorption in posttreatment orthodontic patients, if severe, may jeopardize the retention of the tooth or teeth involved. Numerous studies (1-5) have been undertaken to determine the relationship between the frequency and severity of external root resorption and orthodontic movement. Some investigators found the incidence of root resorption to be low (6-9), while others found it t...
متن کاملExternal apical root resorption following orthodontic treatment.
This study investigated the association of appliance type and tooth extraction with the incidence of external apical root resorption (EARR) of posterior teeth following orthodontic treatment. Pre- and posttreatment orthopantomograms were compared for 97 patients and a 4-grade ordinal scale used to measure EARR. The incidence of EARR was positively associated with tooth position (P < .001), appl...
متن کاملA Scanning Electron Microscopic Study of the Patterns of External Root Resorption under Different Conditions
OBJECTIVE The aim of this study was to examine if there are qualitative differences in the appearance of external root resorption patterns of primary teeth undergoing physiologic resorption and permanent teeth undergoing pathological root resorption in different conditions. MATERIAL AND METHODS A total of 40 teeth undergoing external root resorption in different conditions were divided into 4...
