Oral malodor in companion animals is noticed by owners at first and it makes owners unpleasant. Therefore oral malodor affects the relationship between pet and owner. Oral malodor is produced by some putrefactive bacteria which putrefy proteins to volatile sulfur compounds (VSC) such as methyl mercaptan, hydrogen sulfide and dimethyl sulfide in the food remnants. And oral malodor is mostly consisted with these VSC. On oral examinations in dogs with oral malodor, it is common that plaque and calculus index were increased than normal dogs'. But organoleptic method is subjective to evaluate halitosis, in this study we measured VSC using organoleptic method and portable sulfide monitor to clarify the relationship between halitosis and periodontal disease in dogs with halitosis. And we found that plaque index and calculus index were significantly related with VSC (P<0.05, P<0.05) in measurement using Halimeter. However there was not significant relationship between gingivitis index and VSC. In conclusion, there was the significant, positive relationship between periodontal disease and halitosis.

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 this study was to reveal analyze the relationship between status of participation in an oral health care program and oral health outcomes among patients in Korea, and to evaluate the results to provide evidence regarding the feasibility of widespread implementation of the program. Patients were designated as either cooperative or non-cooperative with the oral health care program and were assigned to each group accordingly. Modified dental hygiene process (M-DHP) of the oral healthcare program was modified to form the dental hygiene process. The study included 48 patients at a dental clinic in Busan, Korea. Questionnaires were used to collect information on oral health behavior (OHB), clinical examination was used to record bleeding on probing (BOP) and O'Leary index, and phase microscopy was used to identify microorganisms. Differences between groups were evaluated using repeated measures ANOVA. Our results showed that the group cooperative with the oral health care program showed greater improvement in OHB, BOP, and O'Leary index than the non-cooperative group. Second, patient satisfaction with the M-DHP was very high, particularly for content and the friendly nature of the staff. The cooperative group showed greater improvement in oral health than the non-cooperative group for all metrics. Our results suggest that this low-coste program, if implemented, would be actively accepted and utilized in dental clinics.

Purpose. The purpose of this study was to compare the type and frequency of prosthetic complications associated with attachment types for implant overdenture. Material and methods. In this retrospective study, 38 patients (mean age, 63.5 years) have been treated with implant overdentures from 2007 to 2014. Ten patients received a bar-clip attachment. Eleven patients had received a milled bar with Locator attachment. Seventeen patients had received a Locator attachment. The mean follow-up period was 36.9 months (range, 15-83 months). The type and frequency of prosthetic complications was recorded. The frequency was analyzed to determine the statistical difference among the 3 different attachments by using one-way ANOVA (${\alpha}=.05$) and Bonferroni post hoc method at a 5% level of significance. Results. The total number of prosthetic complications was higher in the bar-clip attachment (55 events) than in the milled bar with Locator attachment (39 events) and the Locator attachment (34 events). There were no statistically significant differences, and the most common prosthetic complication was the loss of retention. In the bar-clip attachment group, the average frequency of prosthetic complications was 3.0 events per prosthesis during the first year. In the milled bar with Locator attachment and Locator attachment groups, the average frequencies were 1.45 events and 2.35 events, respectively. Statistically significant differences were observed in the frequency of the complication. (p = .043) Conclusions. Compared to the bar-clip attachment, implant overdentures that use milled bars with the Locator attachment have a significantly lower incidence of prosthetic complications in the first year of follow-up after placement.

The purpose of this study was to examine the oral health status and oral health care of adults using dental clinics and the relationship between their oral health state and oral health care. The subjects in this study were 219 patients who visited dental clinics in Gyeonggi province between February and April 2008. A dental checkup and survey were implemented, and SPSS 12.0 program was utilized to analyze the collected data. The findings of the study were as follows: 1. The DT, MT and FT rates of the respondents who used oral hygiene supplies respectively stood at 30.7, 24.6 and 24.6 percent, which were all low. The gaps between them and the others were statistically significant. The DMFT index of the users of oral hygiene supplies was 12.3, which was high, but the difference between them and the others was not statistically significant. 2. The DT rate of those who got a dental checkup on a regular basis stood at 20.8 percent, which was low. The gap between them and the others was statistically significant. Both the MT and FT rates of the former numbered 28.8 percent, which was low, but the gap between them and the others was statistically insignificant. The DMFT index of the respondents who got a regular dental checkup was 12.8, which was high, and the gap between them and the others was statistically significant. 3. The DT and FT rates of respondents who had ever had their teeth scaled respectively stood at 24.6 and 27.1 percent, which were both low, and the differences between them and the others were statistically significant. The MT rate of the former was 27.1 percent, which was low, but the gap between them and the others was statistically insignificant. The DMFT index of those who had ever had their teeth scaled was 12.2, which was high, and the gap between them and the others was statistically significant. The above mentioned findings suggested that there was a very close relationship between oral health care and oral health status. Therefore people in general should be encouraged to pay more attention to their own oral health care, and they should be well informed about how to take care of the oral cavity to promote their oral health.

The purpose of this study was to analyze the relationship between objective oral health status determined by dentists, self-perceived subjective oral health status, and oral health related quality of life (OHRQoL) in the elderly. The related factors affecting OHRQoL in the elderly were also surveyed. Four hundred and thirty elderly individuals who visited the three public health centers and four dental clinics in Busan were selected by convenience sampling. Twelve dental hygienists investigated the subjective oral health status and OHRQoL using the 14-item Oral Health Impact Profile (OHIP-14) and twentyone dentists examined the objective oral health status, including healthy remaining teeth, treated remaining teeth, functional remaining teeth, missing teeth, and non-treated missing teeth. Data were analyzed using SPSS ver. 12.0. OHRQoL was higher when oral and periodontal status was perceived as healthy, when there was no toothache, no interference in mastication, and when study subjects had the ability of food softening. It was also higher when study subjects had ${\geq}20$ remaining teeth and <9 missing teeth, and were wearing denture. The related factors affecting OHRQoL of the elderly were the type of medical insurance, toothache, ability of food softening, perception of periodontal status, and the number of healthy remaining teeth. There was a significant relationship between the subjective-objective oral health status and OHRQoL in the elderly. A continuous oral health care system aimed at retaining ${\geq}20$ healthy remaining teeth is needed to improve oral health and OHRQoL for the elderly, especially for the elderly receiving medical aid.

Objectives: This study aimed to evaluate the relationship between oral health professionals' knowledge, attitude, and practice with regard to infectious waste management and to identify related factors influencing it. Methods: The study comprised of 219 oral health professionals from select dental clinics and public health centers recruited between August 25, 2016 and September 5, 2016, who agreed to participate in the study with full understanding of the study objectives. A self-reported questionnaire was administered, which consisted of 22 items on knowledge of infectious waste management, 9 items on attitude, and 16 items on practice. Data were analyzed using Pearson's correlation coefficient and stepwise multiple regression analyses. Results: The age, knowledge, and clinical attitude of oral health professionals significantly correlated with waste management practice. Specifically, infectious waste management practice improved with increasing age, a greater level of knowledge, and a more positive clinical attitude. Additionally, the standardized regression coefficient demonstrated that, of these three factors, clinical attitude more strongly correlated with effective waste management practice, followed by age and level of knowledge. Conclusions: These results indicated that oral health professionals had a low level of knowledge regarding infectious waste management, and a more positive clinical attitude resulted in better practices. Therefore, the development of detailed and active education guidelines and strategies are needed to enhance the attitude, knowledge, and practice of oral health professionals with regard to infectious waste management.
