This study was conducted to investigate the apraxia affects activitys of daily living. 38 patients with stroke were participated and conducted to both Birminham Cognitive Screen(BCoS) apraxia test and K-MBI for ADL. Using a cutoff score of BCoS apraxia test, all patient was determine whether with apraxia or not and were distinguished by various types of apraxia. They were compared to the level of ADL using ANOVA. Apraxia patients 18, patients without apraxia is 20. The difference of ADL between the two groups was not. However, the result of classifying patients with apraxia subtypes, it showed a significant difference in grooming, eating, toileting, step, bowel control, and bladder control(F=4.431~9.193, p<0.05). As apraxia is cause of a negative effect on ADL, expert in the area to manage stroke patients should have to share information about whether apraxia is or not and make policy and treatment program considering the potential problem in ADL.

The purpose of this study was to examine the effects of the burnout of dental hygienists on their job commitment. The subjects were 156 dental hygienists. Structured questionnaire surveys were conducted. Maslash Burnout Inventory scale and the tool developed by Kang was used. The burnout and job commitment was each divided into three factors; emotional depletion, accomplishment decrease and dehumanizing and organizational commitment, career commitment, and work commitment. The dental hygienists' burnout score was 3.77 points and commitment score was 3.53 points. Burnout was higher among those with clinical careers shorter than five years and smaller numbers of colleague. Those with higher burnout showed higher career involvement and those with longer careers and higher salaries showed higher organizational commitment. Dental hygienists' career that higher burnout was associated with lower degrees of job commitment. Therefore, efficient manpower management should be ways to maintain of their carrer and increase the salary.

Purpose: To compare different radiographic methods for assessing endodontically treated teeth. Materials and Methods: Root canal treatments were applied in 120 extracted mandibular teeth, which were divided into four groups: (1) ideal root canal treatment (60 teeth), (2) insufficient lateral condensation (20 teeth), (3) root canals filled short of the apex (20 teeth), (4) overfilled root canal treatment (20 teeth). The teeth were imaged using intraoral film, panoramic film, digital intraoral systems (CCD and PSP), CCD obtained with portable X-ray source, digital panoramic, and CBCT images obtained at 0.3 $mm^3$ and 0.2 $mm^3$ voxel size. Images were evaluated separately by three observers, twice. Kappa coefficients were calculated. The percentage of correct readings obtained from each modality was calculated and compared using a t-test (p<0.05). Results: The intra-observer kappa for each observer ranged between 0.327 and 0.849. The inter-observer kappa for each observer for both readings ranged between 0.312 and 0.749. For the ideal root canal treatment group, CBCT with 0.2 $mm^3$ voxel images revealed the best results. For insufficient lateral condensation, the best readings were found with periapical film followed by CCD and PSP. The assessment of teeth with root canals filled short of the apex showed the highest percentage of correct readings by CBCT and CCD. For the overfilled canal treatment group, PSP images and conventional periapical film radiographs had the best scores. Conclusion: CBCT was found to be successful in the assessment of teeth with ideal root canal treatment and teeth with canals filled short of the apex.

Purpose: The attachment level is strongly associated with tooth loss and provides useful information on patterns of destruction of the periodontium. The presence of horizontal attachment loss would not be detected in clinical measurement. Therefore, the purpose of the present study was to estimate the patterns of periodontal destruction based on the attachment area and horizontal attachment loss in extracted teeth due to severe periodontitis. Materials and Methods: 307 teeth satisfied the criteria for assessment. An indirect method, based on digital images obtained from a digital camera and an image analysis program, was used to calculate the area of root surface and attachment loss and the extent of horizontal attachment loss. The data were analysed using SPSS. Results: No statistically significant differences among root surfaces were observed in anterior teeth on the loss of attachment area. However, in posterior teeth statistically significant differences in palatal surfaces of maxillary and mandibular premolar and molar surfaces compared with buccal surfaces were observed. Horizontal attachment loss was observed in 21.5% of the teeth examined. Frequency of horizontal attachment loss was highest in the maxillary first premolar (34.8%), followed by the maxillary second premolar (27.3%) and maxillary canine (25%). The mean length of horizontal attachment loss was 1.5mm. Conclusion: More meticulous examination will be needed of the palatal surfaces of maxillary and mandibular premolar and molar teeth. The percentage of teeth with horizontal attachment loss greater than 2.1 mm was 5.2%. Considering the length of curette blades, about 5.2% of teeth were not properly debrided. Therefore, Additional supportive therapy such as local drug delivery has to be considered in treatment of the first maxillary, second premolar and canine due to the high prevalence of horizontal attachment loss.
