The purpose of this study is to analyze trends in the prevalence of dental caries and demand for dental caries treatment among children under 14 years old using Health Insurance Review and Assessment data. The analysis was conducted using treatment records from a random sample of approximately 1 million pediatric patients from a population that included all children and adolescents for each year from 2011 to 2020. In this study, the number of children diagnosed with K02 dental caries and the number of children receiving dental caries treatment across all ages have increased. However, the number of children aged 10 to 14 who received pulp treatment or extraction has decreased. In the National Survey of Children's Oral Health, the decay-missing-filled teeth index for 5- and 12-year-olds has stagnated or increased slightly, but the percentage of the population with active dental caries has decreased. Accessibility and local environments for dental caries treatment have generally improved compared to the past, but preventive dental care has stagnated over the past decade. Therefore, it is necessary to evaluate the effectiveness of oral health programs implemented in Korea to promote and prevent dental caries among children.

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.
