Immature permanent teeth with apical periodontitis and abscess treated by regenerative endodontic treatment using calcium hydroxide and MTA: a report of two cases

Regenerative endodontic techniques have been introduced to overcome the limits of the traditional apexification approach and allow continued root development after treatment of infected immature permanent teeth. The purpose of this report was to describe two cases with severe apical periodontitis and abscess that were successfully treated by regenerative endodontic treatment using calcium hydroxide. The report involves treatment of two patients who developed apical periodontitis and abscesses on their immature premolars affected by dens evaginatus. Regenerative endodontic treatment was performed using calcium hydroxide. The treatment procedures have been shown to result in increased thickening of root walls and encourage continued root development. Different outcomes were observed when calcium hydroxide was placed past and within the coronal half of the canal. Calcium hydroxide can be used as an effective medicament in regenerative endodontic technique, and successful regeneration can be expected even in severe cases of apical periodontitis or abscess

Dental Treatment of a Patient with Hallervorden-Spatz Disease under General Anesthesia -A Case Report-

Hallervorden-Spatz disease (HSD) is a rare autosomal recessive disorder associated with excessive iron deposition in the basal ganglia. In general, HSD is characterized by onset in first two decade of life and by the presence of extra-pyramidal dysfunction including dystonia, rigidity, choreoathetosis. Other associated features include gait and posture disturbance, intellectual decline, seizure, tremor, dysarthria. These signs and symptoms are progressive. MRI is often demonstrated hypodensity in the basal ganglia which is probably suggestive of accumulation of iron. There is no specific treatment for HSD and 45% of patients die before reaching the age of 20 years. The managements directed at specific symptoms are often helpful. Especially, some surgical procedures like pallidotomy and gastrostomy are performed under general anesthesia. There is special need for careful management because of numerous anesthetic challenges like difficulty in cooperation, life-threatening airway obstruction and possibility of aspiration. We report a successful anesthetic management in a patient with HSD for dental procedures

Upper and lower cuspids are very important teeth in point of function as well as esthetic. However, failure of eruption of the canine sometimes happens and is frequently encountered clinical problems. Upper cuspids are more frequently impacted as compared with lower cuspis and palatally impaction is more frequent event than labially impaction. Impaction of the mandibular canine is unusual event, especially crossing the midline (transmigration) is very rare. Because of, in most cases, there is no signs and symptoms, impacted teeth can be detected by periodic radiograph examination. The etiology of impaction is unclear and multifactorial. The treatment of impacted canine is influenced by presence of obstacles, location and direction of impaction, space for alignment and development of root. There are several treatment options; (1) Surgical removal and/or observation, (2) Window opening and orthodontic traction, (3) Autotransplantation. The first patient (impaction of upper right cuspid) is treated with window opening and orthodontic traction. The second patient (bilaterally impaction of lower cuspids) is treated with autotransplantation, because of transmigration

부분 치수절단술을 이용한 복잡 치관파절의 치료 : 증례보고

Traumatic crown fracture in mixed dentition or early permanent dentition is relatively common. Crown fracture is classified into simple or complicated crown fracture by the presence of pulp exposure. The condition of pulp must be considered in treatment of crown fractures with pulp exposure. Treatment of immature crown-fractured incisor with pulp exposure is more complex because of its incomplete root formation. Pulp capping, partial pulpotomy, cervical pulpotomy can be used for continuous root development in immature crown-fractured incisor with pulp exposure. The success rate of partial pulpotomy is very high and there are several advantages of partial pulpotomy because the cell-rich coronal pulp tissue is preserved. This paper reports 2 cases of crown-fractured permanent incisors with pulp exposure that had been treated by partial pulpotomy successfully
