Objective
External root resorption (ERR) is multifactorial,
leading to progressive destruction and eventual loss of tooth root dentin and
cement. It is primarily caused by trauma, pulpal infection, tooth bleaching,
and orthodontic treatment, but its exact cause and pathogenesis remain poorly
understood. The intricate irregularities of ERR can pose a challenge in
accurately filling the root canals. Mineral Trioxide Aggregate (MTA) is a
potential material to fill the this type damaged tissues. The following case
describe the treatment of ERR using orthograde MTA application method.
Case presentation
A 42-year-old female patient was visited to our clinic
for a routine dental control. In intraoral examination, the teeth 11 and 21 did
not respond to vitality test. Radiologic examination showed the presence of a
periapical lesion, including the apical root end of the teeth 11 and 21 and
also the tooth 21 has an ERR in the middle third of the root. After informing
the patient, it was decided to manage the treatment of ERR using orthograde
MTA. The root canals were shaped and irrigated properly. Calcium hydroxide was
placed as an intracanal medicament for 1-week. At the second visit, the RCT of
tooth 11 was completed conventionally. But, in tooth 21, the apical third of
the root canal was filled with gutta-percha and a sealer until the resorption
area. MTA was placed in the resorption area and coronal third of the canal
filled with a warm vertical filling technique. At 1-year follow-up, the result
was satisfactory and post-treatment periapical radiograph showed no periapical
lesion.
Conclusion
Orthograde filling with MTA followed was performed as
nonsurgical approach in ERR and showed no progression of defect. It has been
observed that MTA provides healing, thus immediately restoring the function of
the tooth. Proper
management allows clinicians to achieve successful treatment outcomes.
