Icariin regulates osteoclast differentiation via the OPG/RANKL ratio, evoking a reparative effect on rapid palatal expansion induced root resorption
Internal root resorption
was regarded as a failure in all instances.
Authored by Karl Keiser, DDS, MS, an associate professor and interim director of Advanced Education in Endodontics at the University of Texas Health Science Center, this guide presents an overview of the various types of tooth root resorption
and discusses diagnosis, management and associated prognoses of teeth affected with this condition.
was observed in 81 cases (77%) and in more than 58 cases (55%) this was inflammatory root resorption
Follow-up: Post-operative restorative and orthodontic treatment was completed and four-year review demonstrated continued pulp and periodontal health with no evidence of periapical pathology or root resorption
However, root resorption
and superimposition of permanent successors over primary root apices may obscure root canal length determination through radiographs.
However, the lamina dura around the involved roots in SBCs remains intact and root resorption
is almost never found [Horner et al.
Kurol and Thilander  reported that root resorption
occurred in 21 of 36 mandibular second primary molar roots when there was underlying aplasia.
was detected in 17 of the 55 teeth and for the affected teeth the Andersson index had a mean value of 4.
For the patient it took a number of years for the granulation tissue to ingress into the canal of 11 and for root resorption
Signs or symptoms of inflammation extending beyond coronal pulp, such as swelling, excessive mobility not due to physiological root resorption
, furcal or periapical radiolucency, pathologic root resorption
and excessive bleeding from amputated radicular stumps are contraindications [Fuks, 2000].
It has been postulated that ankylosis can develop during the intermittent processes of root resorption
and bone deposition, which occur in the physiological resorption of the primary tooth root [Kurol and Magnusson, 1984].
