Objectives: To compare the efficacy of intravenous ondansetron (4 mg, 2 mL) and granisetron (2 mg, 2 mL) for preventing postoperative nausea and vomiting (PONV) in patients during oral and maxillofacial surgical procedures under general anesthesia. Materials and Methods: A prospective, randomized, and double blind clinical study was carried out with 60 patients undergoing oral and maxillofacial surgical procedures under general anesthesia. Patients were divided into two groups of 30 individuals each. Approximately two minutes before induction of general anesthesia, each patient received either 4 mg (2 mL) ondansetron or 2 mg (2 mL) granisetron intravenously in a double blind manner. Balanced anesthetic technique was used for all patients. Patients were assessed for episodes of nausea, retching, vomiting, and the need for rescue antiemetic at intervals of 0-2, 3, 6, 12, and 24 hours after surgery. Incidence of complete response and adverse effects were assessed at 24 hours postoperatively. Data was tabulated and subjected to statistical analysis using the chi-square test, unpaired t-test, or the Mann-Whitney U-test as appropriate. A P-value less than 0.05 was considered statistically significant. Results: There was no statistically significant difference between the two groups for incidence of PONV or the need for rescue antiemetic. Both study drugs were well tolerated with minimum adverse effects; the most common adverse effect was headache. The overall incidence of complete response in the granisetron group (86.7%) was significantly higher than the ondansetron group (60.0%). Conclusion: Granisetron at an intravenous dose of 2 mg was found to be safe, well tolerated, and more effective by increasing the incidence of complete response compared to 4 mg intravenous ondansetron when used for antiemetic prophylaxis in maxillofacial surgery patients receiving general anesthesia. Benefits of granisetron include high receptor specificity and high potency, which make it a valuable alternative to ondansetron.

Objectives : The objective of this study was to analyze cognition and status of oral health education of dental hygienists who manage the patients visiting dental clinics and to utilize the findings as continuous study data required for development of systematic oral health education program for management of peridontal disease of adults. Methods : Survey was carried out for 261 dental hygienists working in dental clinics who are performing oral health education of patients with peridontal disease living. Results : 1. In the socio-dynamic diagnosis, it was analyzed that, the younger the age is and the lower the career is, the more the work is centered around assisting medical treatment job and, the older the age is and the higher the career is, the work is centered around oral health education job. 2. In the behavioral diagnosis, it was analyzed that, as to source of knowledge acquisition, guide of dentists and senior dental hygienists was the highest and, as to education media, visual education and demonstration education were mainly used. 3. In educational diagnosis, as to the degree of knowledge about oral health education and the degree of practice, it showed that the degree of knowledge was lower than the degree of practice in peridontal disease process and oral prophylaxis as well as scaling part. 4. In both the cases of independent practice and group practice, it showed that the most frequent obstacle was insufficient educational materials and tools and it was analyzed that acquisition of new knowledge and technology is required as a matter to be improved. Conclusions : It seems to be required for the dental hygienists to develop detailed knowledge and professional technology in order to induce actions and motive of patients during oral health education of peridontal patients and to develop and produce data for efficient education of peridontal patients.

This study was conducted to investigate the effects of noise from dental clinics on workers and to establish a reduction plan. The noise generated by the treatment instrument(Ultrasonic scaler, Hand piece, 3-way syringe, Suction, Compressor) was measured in order to determine the characteristics(level, frequency) of the noise during medical treatment(Oral prophylaxis, Conservation treatment, Prosthesis treatment, Implant Scaling, Tooth eliminating). We also assessed the noise levels in dental clinic using evaluation indicators such as NR-curves and NRN. The results of the analysis showed that the noise generated during the treatment was 85dB(A) ~ 70dB(A) and that the high frequency component was dominant, which would affect the workers working at the dental clinic. The NR-curve analysis showed NR-67 to NR-83 and the high frequency components of 4kHz to 8kHz were predominant and far exceeded noise levels in the workplace. To minimize the noise damage of workers and to provide high quality medical service, it is necessary to establish countermeasures such as wearing a soundproof and periodic hearing tests.

Tooth extraction after head and neck radiotherapy exposes patients to an increased risk for osteoradionecrosis of the jaw. This study reports the results of a radiographic analysis of bone neoformation after tooth extraction in a case series of patients who underwent radiation therapy. No patients developed osteoradionecrosis within a follow-up of 1 year. Complete mucosal repair was observed 30 days after surgery, while no sign of bone formation was observed 2 months after the dental extractions. Pixel intensity and fractal dimension image analyses only showed significant bone formation 12 months after the tooth extractions. These surgical procedures must follow a strict protocol that includes antibiotic prophylaxis and therapy and complete wound closure, since bone formation at the alveolar socket occurs at a slower pace in patients who have undergone head and neck radiotherapy.

본 증례에서는 재생불량성 빈혈 환자의 치료에 있어 감염 가능성과 출혈 가능성을 고려하였으며 의과적 관리와 병행한 치과 치료를 성공적으로 시행하였다. 재생불량성 빈혈 환자의 사망원인은 감염과 출혈이 주를 이루므로 치과의사는 치료하기 전 이와 관련된 혈핵학적 특성을 알아야 하며, 가능한 치과 치료의 범위와 개입 시기를 이에 기반을 두어 판단하여야 한다. 치과 치료 전 혈소판 수치와 절대 호중구수를 고려하여 수혈과 예방적 항생제의 필요 여부를 결정하여야 할 것이다. 또한, 이러한 환자에 있어 예방치료와 구강 위생 관리는 일반 환자에서 중요하다. 주기적 검진 및 구강 위생에 대한 교육이 보다 강조되어야 할 것이다.

Background: The management of the behavior of handicapped children when providing required dental care is often a problem, whether in the dental office or in a hospital setting. Because of the high incidence of poor cooperation, many of these patients are scheduled for dental care under general anesthesia with preoperative medical assessment. The purpose of this study was to carry out a clinico-statistical survey on dental treatment for handicapped children under general anesthesia. Methods: After approval from the institutional review board, the medical records of 64 handicapped children between 1997 and 2002 were reviewed to determine the patient profiles, anesthesia management, and complications. The charts of these patients, who underwent dental examination, scaling and prophylaxis, and restoration and extraction of teeth under general anesthesia, were reviewed. Results: The mean age was 12.8 years old, and males (53%) predominated females (47%). Twenty-four patients had mental retardation, twelve had autism, six had cerebral palsy, 4 had behavior disorder, others had heart disease, convulsive disorder, etc. Sixty-two had intravenous thiopental with neuromuscular blocker, 2 had intravenous ketamine induction. Nasotracheal intubation was uneventful in 55 patients, nine had orotracheal intubation because of difficult visualization of the larynx. Twenty-one patients experienced postoperative complications in the recovery room, including epistaxis, nasal obstruction, vomiting, airway obstruction, respiratory depression. Conclusions: General anesthesia is a very effective way of completing the dental treatments for disabled children. We emphasize the need to train anesthesiologists in the care of disabled patients.

Objectives: The goal of the study was to investigate the clinical effects of amoxicillin-clavulanic acid (500+125 mg) with metronidazole 400 mg administered three times daily (Group I) versus azithromycin 500 mg administered once daily and with metronidazole 400 mg three times daily (Group II) for the prevention of postoperative infection following mandibular third molar surgical removal. Materials and Methods: The study design was a single-center prospective study. Patients who reported to the Department of Oral and Maxillofacial Surgery between February 2015 and January 2017 for removal of mandibular third molar were screened, and 108 patients were chosen. One surgeon carried out all procedures. Patients were prescribed antibiotics until the two groups contained a similar number of cases. Results: Our data showed that Group II had fewer incidences of surgical site infection, but with no statistical significance. Conclusion: Although both treatments are used routinely after removal of the mandibular third molar, neither is significantly better than the other.

An 11-year-old, castrated Maltese dog presented with a 3-week history of periocular swelling, epiphora, and intermittent strabismus. On examination, a foreign body was observed in the anterior chamber, along with orbital cellulitis. Severe gingivitis and plaque accumulation were also diagnosed. The foreign body was surgically removed, and dental prophylaxis and dental extraction were performed. The foreign body entrance could not be found intraoperatively, and the foreign body, later identified as a feather, was removed through a clear corneal incision. The right maxillary molar, which had periodontal inflammation, was also extracted. One day postoperatively, severe hypopyon developed, although the periocular swelling was reduced. These signs persisted despite topical and systemic antibiotic and anti-inflammatory therapy; therefore, the right eye was enucleated 1 week later. Intraoperatively, a fistula was found connecting the orbital medial wall, right maxillary molar root, and sclera. The fistula entered the dorsomedial sclera approximately 7 mm behind the limbus. Enterobacteria were cultured from the area. Foreign bodies can enter the anterior chamber not only through the cornea, but also through the mouth. Therefore, when the entry point cannot be found in the cornea, a careful dental examination is required, and the foreign body must be removed through the sclera rather than the cornea.

This study was to identify oral health status, O'Leary index and OIDP for the preventive oral prophylaxis among adults who visited dental hospitals or clinics from 30th September in 2011 to 31th May in 2012. The results are as follows. In DMFT, female(8.79) was higher than male(7.65)(p<.05). Housewife(9.70) and agriculture fishery industry was higher than others(p<.01). In O'Leary index, male(47.41), over 50 years old and 200~300 million won were higher than others. but these results wasn't significantly different. The majority answer about discomfort feeling in OIDP was during meal(66.7), and period of discomfort was 1~2 time/month(29.6). The discomfort feeling in OIDP effected on meal(40.8)and teeth brushing(50.0). The difficulty in daily life were toothache(21.0), cold feeling(20.8), and crowding(19.3). In conclusion, the negative factor of oral health status didn't effect daily life. These findings are require of development of oral health management program which included the prevention of toothache and cold feeling.
