This study purported to evaluate the performance of the appointment system for outpatients in primary care dental clinic. The data of patients' time flow for 1,245 patients in Y Dental Clinic were collected for one month in 2002 and then analyzed. Specifically, the time periods of treatment and patients' waiting as well as rates of appointment and it's failure are estimated. The accuracy of expected treatment time period was also evaluated. The results showed that 72% of patients visited the clinic with appointments, and only 56% kept their appointments. The patient's waiting time period turned out to be 11 minutes in Y clinic. The expected treatment time period is turned out to be very important because they influence significantly on patient's waiting time period. Practically, the expected treatment time period should be overestimated about 9 minutes in general, and the characteristics of dentist, each patient's diagnosis and age need to be especially considered. Hospitals and clinics also need to make the systematic and detailed critical pathways for a variety of patient cases by analyzing the patients' treatment pattern. With the improved appointment systems, healthcare institutions will approach the goal of effective and efficient management of the institution and also satisfy their customers.

PURPOSE. The purpose of this study is to determine the efficacy of the DENTIS submerged-type implant with an internal hex connection and to build corresponding abutment-selection criteria. MATERIAL AND METHODS. A total of 204 patients received submerged implant fixtures with an internal hex connection at the Dong-A University Hospital Dental clinic in Busan from January 2013 and May 2016. Three specific abutments, UCLA abutments, customized abutments, ready-made abutments, were randomly selected. Implant success was defined as the basis of the International Congress of Oral Implantologists(ICOI, 2007) criteria. The relationship between the implant success rate and the abutment factor was analyzed using the Kruskal-Wallis test(P<.05). RESULTS. A total of 508 implants were placed in 204 patients. After a mean observation period of 38.6 months, 493 out of 508 implants were in normal function, yielding an overall success rate of 97.05%. A total of 15 implants failed: 10 in the maxillary molar area, 4 in the mandibular molar area, and 1 in the mandibular incisal area. All of the implant failures occurred in a single-implant prosthesis, especially high in the maxillary molar area. The Kruskal-Wallis analysis showed that abutment selection has no significant correlation with implant failure(P>.05). CONCLUSION. DENTIS submerged implants with an internal hex connection showed predictable results with a success rate of 97.05%. It is no influence on the success rate in the selection of submerged implant abutment with an internal hex connection.

The purpose of the study is exploring the relationship among patient perceived quality of dental care, satisfaction, and royalty in dental clinics and hospitals. The observation of the study is outpatient visiting dental clinics and hospitals located in Seoul and Kyung-Gi Do area, and surveyed the outpatients. The contents of the survey are consisted with questions including quality of care perceived by the patients, costumer satisfaction, and royalty, and measurement for each question is using five point Likert scale. According to result of bi-variate analysis, there was the significant relationship among specialized care, value of the care, and kindness in quality of dental services, level of care in dentists significantly influenced on costumer satisfaction and costumer royalty, and there was the significant relationship between costumer satisfaction and royalty. According to result of regression analysis on the costumer satisfaction, the costumer satisfaction positively related with the convenience of facility, specialized care, value of care, patient age, number of visit, and spend time for treatment, and housewives and self-employees were likely to satisfy on care than regular employees. By result of full regression model and reduced model on costumer royalty, satisfaction could explain 86% on the costumer royalty such as re-visit and promoting other people, and increase of explain power is not significant when other independent variables joined model (full model). Considering efficiency of model, costumer royalty could be explained by satisfaction only rather than other independent variables used. Finally, This study shows that the social-demographic variables of patient influenced the patient satisfaction, and the patient satisfaction influenced patient royalty directly.

Background: This retrospective study investigated the incidence rate of accidental foreign body aspiration and ingestion according to patient sex, age, and dental department. This study aimed to verify whether the incidence rate is higher in geriatric than in younger patients and whether it is different among dental departments. Methods: Accidental foreign body aspiration and ingestion cases were collected from electronic health records and the safety report system of Yonsei University Dental Hospital from January 2011 to December 2017. The collected data included patients' age, sex, medical conditions, treatment procedures, and foreign objects that were accidentally aspirated or ingested. The incidence rate was calculated as the number of accidental foreign body aspirations and ingestions relative to the total number of patient visits. Differences depending on the patients' sex, age, and dental department were statistically identified. Results: There were 2 aspiration and 37 ingestion cases during the 7-year analysis period. The male to female incidence ratio was 2.8:1. The incidence rate increased with age and increased rapidly among those aged 80 years or older. Seven of the 37 patients with accidental foreign body ingestion had intellectual disability, Lou Gehrig's disease, dystonia, or oral and maxillofacial cancer. The incidence rate was highest in the Predoctoral Student Clinic and the Department of Prosthodontics. The most frequently swallowed objects were fixed dental prostheses and dental implant components. Conclusion: The incidence rate of accidental foreign body aspiration and ingestion differed according to patient sex, age, and dental department. Dental practitioners must identify high-risk patients and apply various methods to prevent accidental foreign body aspiration and ingestion in dental clinics. Inexperienced practitioners should be particularly careful.

A 2-year-old, castrated male, Scottish fold cat was referred to Veterinary Medical Teaching Hospital of Seoul National University (VMTH-SNU) for evaluation of acute bilateral blindness after general anesthesia. For dental prophylaxis in local animal hospital, general anesthesia had been induced with intravenous acepromazine and ketamine, and maintained with isoflurane after intubation. At VMTH-SNU on next day, complete blood count, electrolytes and serum chemistry values were within normal ranges. On neurologic examination, visual placing and postural reactions like as hopping, hemiwalking and wheelborrowing were reduced on right hindlimb. On ophthalmic examination, menace responses were absent on both eyes and pupillary light reflex (PLR) reduced on right eye, but other reflex and fundus were normal. Prednisolone (2 mg/kg sid for 3 days) was administrated orally and tapered. Visual placing was possible on 2nd day, and postural reactions were recovered on 4th day after dental prophylaxis. Based on the process and recovery, this case was considered as postoperative visual loss (POVL) after general anesthesia.
