Objectives; The purpose of the present study is to investigate the difference in levels of satisfaction between dental laboratory owners and employed dental technicians in the area of dental laboratory management. Methods; The samples of seventy-one dental laboratory owners and sixty-six employed dental technicians were selected in a blinded and random manner. Data was collected through self-administered questionnaires and analyzed using average values, the t-test and multiple regression. Results; 1) There was no significant difference in the average values of general satisfaction levels related to dental laboratory management between dental lab owners and employees. 2) The average values of satisfaction levels in 11 specific items scored 'above average' among dental lab owners and 'average' among employees. 3) The average values of satisfaction levels in 10 specific items except for 'trust and respect' showed a significant difference between dental lab owners and employees. 4) Important factors which influenced the satisfaction level of dental lab owners were 'trust and respect' and 'improvement of employee's benefits'. In the employees group, 'trust and respect', 'improvement of employee's benefits' and 'technical information support' were important factors. Conclusion; The present study revealed that dental laboratory owners and employees have some gaps between the viewpoints in dental laboratory management. This suggests the necessity to improve management in a transparent and economical way. However this study has some limitation in that the sample size was not massive enough.

Objectives; The purpose of the present study is to investigate workplace satisfaction level of dental technicians and the differences between that of dental lab owner's and that of employed dental technicians, who are working in dental laboratories. Methods; Samples were comprised of 137 dental technicians working in dental laboratories. Data were collected through self-administered questionnaires and analyzed to frequency distribution, correlation, t-test and multiple regression analysis. Results; 1) Dental technicians generally are 'somewhat or a bit satisfied' with their workplace situations, regardless of position, sex, and individual career. 2) Mean values of 4 items out of 11 work situation factors of employed dental technicians were significantly lower than those of lab owner's. The 4 items are the openness of management, working environment, pay, and policy in promotion and raise. They would be sources of dissatisfaction and conflict. 3) Level of satisfaction was significantly correlated with 2 subordinate variables, i.e. working conditions and administration policy. There is a tendency that administration policy is a bit more important for lab owners, while working conditions are a bit more important for employed dental technicians. Conclusion; The employer-employee relationship of dental technicians seems to be sound, as no signs of troublesome problem is detected. But the discrepancy revealed in the above results is telling that there certainly exist some disagreement in the viewpoints of the two groups. It is necessary for the dental technicians to find ways to deal with the possible triggers of discord and discontent.

The organization to which we belong is the place where we make social relationships, satisfy our desires of self-realization, and accomplish our common object. The emotional and psychological state of individual as well as the whole organization is able to be explained in the concept of morale. The researcher selected a total 238 dental technicians living in seoul, and conducted a research in a period ranging from April 1, 2004, to April1 10, 2004. The researcher analyzed the findings with the aid of SPSS (Statistical package for social sciences). The researcher came to reach the following conclusions on the basis of frequency, percentage, T-test, F-test, and multiple regression. The results of this study were as follows: First, there is a significant difference in recognizing morale due to their age, academic background, their work places, position, part of objective, and working hours(p<.05). Secondly, The researcher there is a significant difference in recognizing due to their social welfare, payment, fair and objective personnel management, enough opportunities of self development, and autonomy(p<.05). Lastly, this study is very limited in generalization because it deals with a small part of morale management plans and objectifies very limited organization. But, it is very meaningful in trying to approach morale management plans with an object of dental technicians. It is necessary that dental technicians should make efforts to control themselves.

Purpose: The purpose of this study was to investigate dental technicians' awareness of infections and to enhance their interest and commitment towards infection prevention. Methods: A self-reported questionnaire survey was conducted among dental technicians. Total of 195 responses were used for analysis. A cross-tabulation analysis was used to compare dental technicians' awareness of infections according to their levels of education on infection prevention (α=0.05). Results: Dental technicians were educated on infection prevention (40.5%). Most participants received infection prevention education from school (29.8%). Dental laboratories had an infection control guideline (34.9%). Dental technicians were not aware of infection risks at their workplaces or believed that they were not at risk of infections at their workplaces (59.3%). Conclusion: Dental technicians must be consistently educated on infection prevention and control through systematic education at school and wider promotion through media. Research is needed to economically and efficiently improve equipment used by dental technicians and to protect them from infectious diseases. A budget for infection prevention must also be determined. Institutional measures such as providing support for dental technicians at the policy level and developing a basic infection prevention manual are necessary. Solving these issues not only protects dental technicians from infections but also allows them to provide high-quality medical services.

Objectives: The mandible and other parts of the maxillofacial region suffer significant morbid injuries following road traffic accidents. Our study gives epidemiological description of mandibular fractures in Ghana and also evaluates the relevance of closed reduction and indirect fixation for managing mandibular fractures in low-resource health facilities in low-income countries like Ghana. Patients and Methods: This is a retrospective study involving 268 patients who reported to the Department of Oral and Maxillofacial Surgery of the Sunyani Regional Hospital with mandibular fractures from January 2010 to December 2019. Patient medical records were assessed for information on age, sex, fracture etiology, anatomic location of fracture, time of day of road traffic accident, and other associated injuries. Results: A total of 268 patients were included in this study (males, 216 [80.6%]; females, 52 [19.4%]). Motor vehicular accident (MVA) was the leading cause of mandibular fractures (202 injuries, 75.4%). Other etiologies included assault (39, 14.6%), gunshot (13, 4.9%), falls (12, 4.5%), and industrial accidents (2, 0.7%). Of the 161 male cases caused by MVA, 121 (75.2%) occurred at night and in the evening while the remaining 40 (24.8%) occurred in the morning and afternoon. Among all managed 222 patients, 212 (79.1%) were treated with closed reduction and indirect fixation technique while 10 (3.7%) were treated with open reduction and direct fixation. Conclusion: Closed reduction with indirect fixation could successfully be used to manage mandibular fractures in low resourced health facilities, especially in low-income countries. The poor lightening system on roads in Ghana is a major contributory factor to motor vehicular accidents.

Background: Head or scalp injury is a life-threatening and typically accidental human injury. Most medical departments require immediate medical treatment and proper treatment with specialized medical personnel and facilities. However, in low-resource environments, such as the rural region of West Africa, the authors have treated emergency trauma patients and provided immediate treatment despite lack of resources. Case presentation: We reviewed three cases of scalp injury patients, with representative clinical information, and used these cases to outline feedback on scalp trauma treatment based on the specialty knowledge of general and emergency surgeon. Conclusions: Oral and maxillofacial surgeons are medical specialists that can immediately diagnose and treat these scalp injuries based on their medical knowledge and experience with the maxillofacial region.

Background: Maxillary sinusitis of odontogenic origin, also known as maxillary sinusitis of dental origin or odontogenic maxillary sinusitis (OMS), is a common disease in dental, otorhinolaryngologic, allergic, general, and maxillofacial contexts. Despite being a well-known disease entity, many cases are referred to otorhinolaryngologists by both doctors and dentists. Thus, early detection and initial diagnosis often fail to detect its odontogenic origin. Main body: We searched recent databases including MEDLINE (PubMed), Embase, and the Cochrane Library using keyword combinations of "odontogenic," "odontogenic infection," "dental origin," "tooth origin," "sinusitis," "maxillary sinus," "maxillary sinusitis," "odontogenic maxillary sinusitis," "Caldwell Luc Procedure (CLP)," "rhinosinusitis," "functional endoscopic sinus surgery (FESS)," "modified endoscopy-assisted maxillary sinus surgery (MESS)," and "paranasal sinus." Aside from the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) trial, there have been very few randomized controlled trials examining OMS. We summarized the resulting data based on our diverse clinical experiences. Conclusion: To promote the most efficient and accurate management of OMS, this article summarizes the clinical features of rhinosinusitis compared with OMS and the pathogenesis, microbiology, diagnosis, and results of prompt consolidated management of OMS that prevent anticipated complications. The true origin of odontogenic infections is also reviewed.

To investigate the perceptions and attitudes of dental hygienists toward radiation safety management in Korea. A total of 800 dental hygienists were randomly selected for an anonymous survey, and 203 of them participated. The questionnaire items included the following: sex, career period, type of installed radiographic equipment, recognition of the diagnostic reference level (DRL), participation in radiation safety education, and attitudes toward radiation protection for both patients and dental hygienists. The participants were divided into two groups according to their years of experience (< 10 years versus ≥ 10 years). The difference between the groups was investigated according to frequency distribution. Fisher's exact test or Pearson's chi-square (𝛘²) test was used as appropriate. A regression analysis was performed to investigate the impact of wearing a thyroid collar for personnel protection during patient radiation exposure. The types of installed radiographic equipment included panoramic radiography (96.1%), cephalometric radiography (76.9%), intraoral radiography (72.9%), and cone-beam computed tomography (69.5%). Significant differences were observed in the learning pathway for the DRL (Fisher's exact test, p < 0.05), satisfaction with radiation safety education (Pearson's 𝛘² test = 5.3975, Pr = 0.02), and use of personnel radiation monitoring systems (Pearson's 𝛘² test = 18.1233, Pr = 0.000) between the groups. Significant differences were also observed in personnel protection using a thyroid collar and patient protection during panoramic radiography (odds ratio = 14.2). Dental hygienists with more than 10 years of experience were more satisfied with radiation safety education and more interested in radiation monitoring. Considering career experience, customized, continuous, and effective radiation safety management education should be provided.
