Management of Traumatic Inflammatory External Root Resorption

Inflammatory external root resorption is one of the major complications after traumatic dental injury. It is characterized by the loss of mineralized dental tissue which may, ultimately, result in loss of the tooth. However, with appropriate treatment, prognosis for these teeth may be greatly improved, by preventing or arresting resorption. This is a case report of an 18-year-old male patient presented with root canal treated maxillary central incisors associated with pain; with history of trauma. Radiographic examination revealed periradicular lesion and associated pathologic resorption of the apical region of the root with respect to 11 and calcification of the root canal with inadequate obturation with respect to 21. After removal of the root canal filling, 11 was disinfected with intracanal double antibiotic paste. After 2 weeks, antibiotic dressing was removed, and apical third was sealed with mineral trioxide aggregate (MTA). Canal was obturated with custom-fit gutta-percha and accessory cones with AH plus sealer and restoration was done with composite resin. Retreatment was also done with respect to 21 and obturated with custom-fit gutta-percha. Both teeth were restored with E-max crown. No clinical symptoms were apparent, significant osseous healing of the periradicular region was observed with arrest of external root resorption with respect to 11 and no periapical changes were apparent with respect to 21 on subsequent follow-up.

External Root Resorption

Inflammatory external root resorption is one of the major complications after traumatic dental injury. In this case report, we describe treatment of a maxillary central incisor affected by severe, perforating external root resorption. An 18-year-old patient presented with a previously traumatized, root-filled maxillary central incisor associated with pain and sinus tract. Radiographic examination revealed periradicular lesion involving pathologic resorption of the apical region of the root and lateral root surface both mesially and distally. After removal of the root canal filling, the tooth was disinfected with intracanal triple antibiotic paste for 2 weeks. The antibiotic dressing was then removed, and the entire root canal was filled with mineral trioxide aggregate. The endodontic access cavity was restored with composite resin. After 18 months, significant osseous healing of the periradicular region and lateral periodontium had occurred with arrest of external root resorption, and no clinical symptoms were apparent.

Root Canal Retreatment

Background: Iatrogenic complications such as accidental perforation of the root or the floor of the pulp chamber may occur. Case Report: Patient was referred for root canal retreatment of the mandibular left second molar with periapical lesion evidenced through radiographic examination. During post removal, iatrogenic perforation occurred at the mesial face of the distal root. After clinical localization of the perforation and bleeding control, MTA was applied. In a second appointment, the root canal filling was removed and the chemical-surgical retreatment of the canals was performed, followed by the obturation with gutta-percha and sealer. Patient returned after three days reporting no pain. After 6 months, 3, 7 and 10 years of follow-up. Conclusion: Absence of pain, normal periodontal probing and lack of radiolucent area at the region of perforation and the periapices were detected, which evidenced the successful repair of the tooth.

Ultrasonic Irrigation

We report the case of a 39-year-old male with Persistent Apical Periodontitis (PAP) caused by infection in an uninstrumented area, wherein conventional chemical root canal treatment is not possible, which was sterilized via highfrequency conduction. He underwent root canal filling after multiple endodontic treatments for tooth #4. As symptoms recurred, he was referred to our department with the chief complaint of dull pain during mastication. Present symptoms were percussion pain of the tooth, buccal mucosa swelling at the apical portion, and grade 1 mobility. Radiography revealed inadequate root canal filling. A radiolucent image 5×6 mm in diameter and with an unclear boundary was observed around the apex. External root resorption was mainly observed in the apical foramen, with a crown root ratio of approximately 1:1. Using 6% sodium hypochlorite under dental microscopy, chemomechanical root canal preparation was performed. Passive ultrasonic irrigation and calcium hydroxide application were conducted three times; however, periapical tissue inflammation did not subside. Therefore, the patient was diagnosed with PAP, and the uninstrumented area was sterilized via high-frequency conduction. High-frequency currents were applied to the apex, root surface, and periapical lesion at 500 kHz and 90 V; periapical tissue inflammation resolved after 2 weeks. Subsequently, the root canal was filled. Follow-up radiography revealed a bone regeneration-like image at 2 months. Bone defects healed at 11 months. Although surgical endodontic therapy is conventionally performed in PAP patients, high-frequency conduction could be a minimally invasive nonsurgical endodontic treatment option for uninstrumented areas in PAP patients.

External Root Resorption

AIM: The aim of this study is to present severe root resorption following obturation of the primary molar with zinc oxide eugenol (ZOE) at different follow-up periods. CASE REPORT: We present the case of a 6-year-old boy with decayed lower primary molars. Pulpectomy for pulpally involved primary molars was performed. ZOE has been used as root canal filling material and follow-up was done at 3, 6, and 9 months. CONCLUSION: External root resorption was detected at 3 months and the resorptive process continued till 9 months. This finding emphasizes the need for alternative filling material with less irritating properties.

The Difference

Aim: The aim of this study was to assess whether an obturation, combining a custom guttapercha cone with the BIOROOTTM-RCS sealer, displays similar sealing quality to the orthograde apical plugs of MTA CAPS1 in immature teeth with irregular wide apices. Methodology: Thirty-four immature permanent premolars with apical diameter varying between (1-3 mm) were chosen for this study and were divided into two groups. They were imbedded in wet sponge, which simulated the periapex. In the first group; 5 mm orthograde plugs of MTAwere placed using an appropriate plugger. In the second group; a custom gutta-percha cone was fabricated and used for root canal filling with the BIOROOTTM-RCS sealer. The specimens were stored at 37 8C and 100% humidity during five weeks to allow the complete set of the filling materials. The apical leakage was evaluated using a dye penetration test with 50%-weight silver-nitrate. The teeth were then embedded in a transparent resin and sectioned transversally at 1 and 3 mm from the apex. The slices were examined under optical microscope and were given scores from (0) to (4). When scoring a slice was difficult, spectroscopy for energy dispersion using a scanning electron-microscope was used to confirm the score. The results were compared using the Fisher test with p < 0.05. Results: Silver-nitrate was found in both groups in all slices at 1 mm. At 3 mm, the difference of micro-leakage was not significant. Conclusions: The custom gutta-percha cone combined with BIOROOTtm-RCS sealer displays similar leakage resistance to the orthograde MTA plugs.
