Authors have selected a physiological bad breath patient( 62 years old, male ) among the bad breath outpatients who have visited the halitosis control clinic in Korea University Medical Center(KUMC). The patient visited the halitosis control clinic for his oral malodor control, 3 times from April to June in 2018, and in August the patient visited to KUMC malodor control clinic again for his assessment of his two months efforts. Getting the data about the patient's endeavor to get over his physiologic oral malodor and the estimation of the patient's satisfaction level at his oral malodor improvement by a questionnaire method, and the organoleptic level assessment by the dentist, then we could propose an estimation method of the physiologic oral malodor patient care prognosis.

Manbojeonseo, a kind of an encyclopedia published several times in Ming Ch'ing dynasty, includes useful information for scholars and common people on daily lives. In 1720, Manbojeonseo was first introduced to Joseon(朝鮮) dynasty by the diplomatic corps visiting Ch'ing dynasty, and widely circulated in the society as an useful information magazine or an individual collection of reference book. Since Manbojeonseo includes the systematically-organized contents of Geumdoron(琴道論, a theory of a heptachord), it could provide a useful reference when the Geumdoron was inserted as the contents of old scores. For an instance, Obultan(五不彈), Tangeumsuji(彈琴須知), and Taeeumgibeop(太音紀法) recorded in Hangeumsinbo(韓琴新譜, 1724) clearly acknowledge Manbojeonseo as their common source. In this paper, the order and the contents of Geumdorons from four different Manbojeonseo are compared. At first, the comparative analysis of Manbojeonseo (1610) edited by Seo Giryong(徐企龍) and Manbojeonseo(1612) edited by Yu Jamyeong(劉子明) are carried out focusing on the contents of the Geumdoron, where both Manbojeonseos contain considerable amount of Geumdoron sections. The tables of the contents in both Manbojeonseos are composed of upper and lower levels classified into 4 large divisions for each. While the contents of the upper level is presumably older and focused more on the theory of the cardinal virtues, the contents of the lower one is relatively new and centered more on the skills for the real play of a heptachord(琴), the lyrics and the musical scores composed of Gamjabo(減字譜). Therefore, it could be said that the upper level is metaphysical while the lower level is physical. One of the differences between those two Manbojeonseos lies in the order and the terminology found in the large divisions. In the case of Manbojeonseo(1612), some terms in the large division represent and theoretically group the detailed descriptions in the small divisions such as 5 demands or 7 taboos in the play of the heptachord. In addition, a few lower divisions were newly added or revised in order to enhance the completeness of Geumhangmun(琴學門, study of a heptachord), and the detailed classification was revised and polished to improve the reasonableness. In Manbojeonseo(1614) composed by the same editor as Manbojeonseo(1610), the contents of the Geumdoron become much briefer than those of Manbojeonseo(1610) and Manbojeonseo(1612). In the case of Manbojeonseo(1739), a new type of the Geumdoron is included called Oeumjeongjobo(五音正操譜) while carrying a similarly brief section of the Geumdoron. Finally, the Geumdorons in Manbojeonseo and several old scores are comparatively analyzed. While the Geumbo(琴譜) owned by Gugagwon(國樂院) and Hangeumsinbo contains relatively old Geumdoron, Yuyeji(遊藝志) and Bangsanhanssigeumbo(芳山韓氏琴譜) adopt practical and relatively new Geumdorons different from the former old scores and similar to Manbojeonseo(1739) considering the order and the contents. In particular, the contents of the Geumdoron in Geumheonakbo(琴軒樂譜) is notably unique containing much of the upper and the lower levels of Manbojeonseo(1612), therefore thought to have actively adopted the contents of new Geumdorons.

The authors have observed a case of adenold cystic carcinoma occured in molar portion of the left mandible in 59-year old woman. The results are as follows: 1. Roentgenographic findings revealed pathological fracture of the left mandibular body. 2. The patient complained of burning sensation of tongue and facial dull pain. 3. Microscopically, in the portion of glandular arrangoment of tumor cells, the mucinous materials were contained, and the mitotic figures of tumor cells did not appear in this case, and the stromal connective tissue revealed hyaline degeneration and myxomatous degeneration. 4. The tumor cells were infiltrated not only perinoural lymphatics, but also perineurum and intraneura tissue.

Choristoma is a growth of normal tissue that occurs at an abnormal region. In the oral cavity, osseous choristoma that has a normal bone feature mainly has been appeared. It is mainly occurred on the tongue. So, It can be found in dental practice or in discomfort in the mouth. Osseous choristoma in the oral cavity is extremely rare. But It can be treated excisional biopsy under local anesthesia. The prognosis is very good. This case is a report of osseous choristoma on the dorsal surface of the tongue. A 17-year-old female patient presented with a foreign body sensation of the tongue. A diameter of the mass is 0.7cm, and there is no pain. Panoramic radiographs showed a radiopaque image in the form of a double image. An excisional biopsy was performed and diagnosed as an osseous choristoma. 12 months after the resection, there were no signs of recurrence. Intraoral osseous choristoma is very rare, but it is clinically very simple and can be found in dental radiographs. We present this case because of Dentists who examine the oral cavity of the patient can easily diagnose the lesion and treat it by simple resection.

Neurofibroma is a benign, heterogenous peripheral nerve sheath tumor arising from the connective tissue of peripheral nerve sheaths, especially the endoneurium. Its intraoral occurrence is uncommon and its occurrence within mandible is extremely rare. A case of solitary intraosseous neurofibroma of the mandible involving masticator space in a 8-year-old male is reported. He was referred from a private local clinic with a chief complaint of limitation in opening of the mouth. Panoramic and cone-beam computed tomographic images showed unilocular radiolucent lesion with scalloped border at the right mandibular ramus, connected posteriorly to the enlarged mandibular foramen and anteriorly to the mandibular canal. T1-weighted magnetic resonance images showed soft tissue mass of isointensity compared with muscles. Contrast-enhanced T1-weighted images showed peripheral enhancement and T2-weighted images showed the heterogeneous hyperintense mass with extension between lateral and medial pterygoid muscles. The tumor was surgically removed under general anesthesia and diagnosed to be neurofibroma at the biopsy.

The authors had observed clinically and histopathologically on the 5 cases of globulomaxillary cysts. The results are as follows: 1. All cases occurred in men, and the average age was 33.6 year,; the oldest was 38 year and the youngest was 31 year old. 2. Four cases occurred in upper left jaw and the one was in right. 3. By the roentgenogram, well demarkated line between the cyst and intact bone were observed as pea shaped radiolucency between the canine and the lateral incisor. In most cases alveolar bone was involved from the central incisor to the premolar region. 4. Thick stratified squamous epithelium was covering the connective tissue wall. There were no keratinization except one case of parakeratosis which had massive inflammatory infiltration. Inflammatory infiltration was obsereved in most cases.

SFI-bar is prefabricated bar system and can be assembled at chairside without soldering or welding, thus reducing bone loss, costs and time. A 53-year-old male patient, who had severely absorbed mandible, hoped to wear a stable mandiblular denture. Four implants were placed in the extraction site of canine and 1st molar. Early loaded temporary denture with solitary type attachment was delivered 3 weeks after surgery. 3 month later, SFI-bar was connected and adjusted at chairside. Then, implant overdenture using SFI-bar was delivered. This case report showed that a satisfactory clinical result was achieved by 4-implant-supported overdenture using the SFI-Bar system in a mandibular edentulous patient.

Peri-apical implant lesion, also known as 'retrograde peri-implantitis' can occur with multifactorial etiological factors. The purpose of this case report is to demonstrate resolution of periapical implant lesion by removal of causative factors and saving implant by regenerative therapy. A 54-year old male patient with mild dull pain around implant on the right mandibular second premolar area due to persistent peri-apical infection of the adjacent first premolar was treated. Extraction of tooth with symptomatic apical periodontitis and regenerative therapy on the buccal fenestration area of the implant and extraction site were performed. After 6-month reentry, notable regenerated bone tissue around implant was found, and implant placement on the previous extraction site was performed. After 14-month follow-up from the regenerative therapy, neither biological nor mechanical complication could be found around the implant, evidenced by high implant stability, normal clinical probing depth, and absence of discomfort spontaneously and during masticatory function. In conclusion, surgical intervention including regenerative therapy using bone graft and barrier membrane on periapical implant lesion can be suggested as one of the treatment options considering the extent of periapical lesion.
