Background: In the current social scene of Japan, there has been a steady growth of female dentists. Nevertheless, studies that delve into the female Japanese perceptions have been scarce.
Objectives: The purpose of this study was to determine the quality of life (QoL) and evaluate the factors affecting job satisfaction of female dentists in Japan.
Materials and Methods: Via a researcher-made questionnaire, a cross-sectional survey was done on a total of 156 Japanese female dentists.
Results: As per the outcome, 80.8% agreed that they have attained satisfaction with their QoL, while 30.8% strongly agreed. The job satisfaction factors were then listed in descending order of statistical significance as ownership type, having children, pursue PhD, marital status, and annual income. Multivariable logistic regression analysis showed significance in the participants' responses pertaining to ownership type (OR = 2.833, p = 0.013) and the pursuance of a post-graduate course immediately after attaining undergraduate education (OR = 0.425, p = 0.046).
Conclusion: Findings suggest that majority of the female dentists in Japan perceive to have attained satisfaction in their QoL. Actual ownership type and immediate pursuance of a post-graduate course were found to be the significant factors related to job satisfaction. This implies that Japanese universities and dental colleges should focus on promoting immediate post-graduate opportunities for female dental graduates.

In recent years, the use of dental magnifying glass has been spreading for the accurate diagnosis and treatments. In this research, we decided to introduce a dental magnifying glass during a practical training course at a training school and to verify its usefulness.
The subjects were 52 2^nd year students enrolled in a prefectural school in 2015 and 51 2^nd year students enrolled in fiscal year 2016, totaling 103 people.
In both 2015 and 2016-from April to November, we introduced a magnifying glass for jaw model practice and mutual practice of the dental preventive treatment subjects. The subjects were asked to detect and remove the artificial dental calculus (protrusions) in phantom head, jaw and teeth models with and without the dental magnifying glass as a practical test. The use effect of dental magnifying glass was evaluated by the total numbers of detected and removed protrusions. After the test, a questionnaire was also conducted to the subjects to subjectively evaluate the use effect of dental magnifying glass.
Both detection and removal numbers with the dental magnifying glass were significantly higher than those without the dental magnifying glass. The result of questionnaire showed a positive attitude toward the use of dental magnifying glass.
By using a magnifying glass in a practical training in a training school, it improved the ability to detect protrusions corresponding to dental calculus, you can gain many benefits such as improving motivation for future hygienist work, it was suggested that its introduction is useful for practical training.

Bone pain is a most common and devastating complication associated with bone diseases such as osteoporosis, bone metastasis and rheumatoid arthritis. Thus, control of bone pain is a major goal in the management of these bone diseases. In bone destructive cancer, opioids are first-line therapy but palliative, unsatisfactory and inadequate. Inhibitors of osteoclasts including bisphosphonates and denosumab incompletely reduce bone pain, indicating that not only osteoclast-dependent but also osteoclast-independent mechanisms are operant. In this review, we introduce the recent study including ours, targeting the cancer cell and osteoclast created-acidic extracellular microenvironment for Cancer-associated Bone Pain (CABP).
