  • Reported causes of mandibular nerve injury in relation to neuropathic pain in dentistry include extraction, dental implant surgery, oral and maxillofacial surgery, periodontal treatment, and root-canal therapy. This study analyzed the characteristics of pharmacologic management of neuropathy after root-canal therapy. 32 patients who complain of abnormal sensation or pain after root-canal therapy and were referred to Department of Oral Medicine and the Temporomandibular Joint and Orofacial Pain Clinic at the Dental Hospital of Yonsei University, Seoul, Korea from 2004 to 2011 enrolled in this analysis and improvement of symptom was evaluated after pharmacologic management. Thirty-two patients who had hypoesthesia or dysesthesia at the initial visit were analyzed(9 men, 23 women; mean age: 44 years). The causes of neuropathy were local anesthesia(46.9%), chemical trauma from the sealant in root-canal(25%), endodontic surgery(15.6%), and unknown causes(12.5%). Medications such as steroids, anticonvulsants, antidepressants, and analgesics were took for improvement of symptoms and titrated for a variety of period from 1 week to 11 months. It was found that neuropathy of the inferior alveolar nerve and the lingual nerve was in 25 and 7 patients. The improvement of neurosensory disturbance and no improvement after pharmacotherapy was in 21(66%) and 11(34%) patients respectively. The hypoesthesia and dysesthesia was improved 67% and 65% respectively. These results suggest that symptomatic improvement by pharmacologic management can be possible in patients with neuropathy after root-canal therapy. But improvement of symptoms was influenced by the causes and degree of nerve injury, the periods of pharmacotherapy, and the choice of treatment methods. So, further investigation is needed by quantitative measurement of more variables in more individuals.

  • Mineral trioxide aggregate (MTA) is widely used in endodontic therapy as a pulp-capping material, root or furcal perforation repair material, and for apexification and obturation of the root canal system. The purpose of this study was to formally document cases of MTA application in South Korean children and adolescents. Through this research, the practice of using MTA will be introduced and familiarized to the clinical practitioners. This study involved endodontic treatment using MTA for fractured crowns in 11- and 12-year-old. The children were followed up for 12 months until the pulp vitality was confirmed; in young permanent teeth with immature roots, the pulp is integral to the process of apexogenesis. These observational results regarding the use of MTA as an apexification material in non-vital immature permanent incisors appear to provide promising results in the search for new materials to meet existing endodontic needs.

  • Numerous challenges in treating permanent dentition are encountered, especially in treating immature teeth with pulp necrosis. Historically, calcium hydroxide application during long periods of time was used to induce the formation of a calcific barrier across the open apex. In 2004, a new treatment modality for the management of the open apex was introduced. This treatment was named as 'revascularization' and gained acceptance among dentists. The protocol was different from the traditional apexification techniques in that the canal was irrigated and disinfected with a combination of three antibiotics (ciprofloxacin, metronidazole and minocycline). At the next appointment, bleeding was induced and the canal was sealed with MTA. Successful regenerative endodontic treatment of necrotic immature permanent teeth can provide continued root development, increased thickness in the dentinal walls and apical closure. These developments of a functional pulp-dentin complex have a promising impact on retaining the natural teeth, the goal of the dental health care.
