[Treatment options for external inflammatory root resorption]

THE AIM OF THE STUDY

Was to compare the efficacy of various treatment options for external inflammatory root resorption according to literature data.

MATERIALS AND METHODS

Literature was searched in electronic databases «eLibrary» and «PubMed» for key words «external inflammatory resorption treatment», «external inflammatory resorption management». Inclusion criteria comprised publications in Russian or English, clinical and experimental studies, full description of treatment protocol and obtained results. Studies with no full text, describing root resorption of orthodontic origin, clinical cases and clinical case series were excluded from the study.

RESULTS

The problem of external inflammatory root resorption is poorly described in the Russian scientific literature. There are no registered protocols for its prevention and treatment or therapeutic agents with proved efficacy available in Russia. The only accessible approach for external inflammatory root resorption remains timely pulp extirpation after dental trauma which importance is underlined by all authors involved in the field of dental trauma studies. MTA and calcium hydroxide being popular as intracanal medications still have significant inconveniences as they potentially provoke root dentine fractures or replacement resorption.

CONCLUSION

There is a need for elaboration and implementation of new prevention and treatment options for external inflammatory root resorption after dental trauma.

Management of root canal stenosis and external inflammatory resorption by surgical root reconstruction using biodentine

Root canal stenosis and external inflammatory root resorption are potential consequence of trauma that can occur depending on the severity of the injury. Luxation injuries induce reduced blood supply to the pulp, which leads to calcification/narrowing of root canals leading to root canal stenosis. External inflammatory cervical resorption occurs when there has been the loss of cementum due to damage to the external surface of tooth root during trauma, plus root canal system becoming infected with bacteria. External inflammatory resorption can ultimately lead to loss of tooth if it is not managed in a timely manner. The treatment should aim toward the complete suppression of all tissues undergoing resorption and the reconstruction of the resorptive defect by the placement of a suitable bioactive material. This case report presents the management of root canal stenosis in the maxillary left central incisor in 35-year-old female and management of Class IV external invasive cervical and apical inflammatory resorption in maxillary right central incisor, both of which were diagnosed with the help of cone-beam computed tomography scan. The treatment of external inflammatory resorption included surgical excision of granulation tissue and root reconstruction with Biodentine. Twelve months follow-up showed successful outcomes for both the teeth treated for root canal stenosis and external invasive inflammatory resorption leading retention of the traumatized teeth with otherwise poor prognosis.
