The aim of this study was to evaluate the efficacy of bleached tooth with white toothpaste on the whitening effect, microhardness test. Forty-four human interior teeth were randomly assigned to two groups as follows: Group 1 was used general toothpaste as control, Group 2 exposed to white toothpaste at 3 times a day for 3 minutes. The total application time was 4 weeks. After each application, all tooth were washed with distilled water and immersed in artificial saliva. The color change and microhardness were measured using CIELab Color system and microhardness tester. The data were analyzed by student t-test, using SPSS 20.0 statistical computer program (SPSS Inc., USA). The overall color changes (${\Delta}E$) by white toothpaste have a capability of the whitening efficacy by factor of 2.3 times larger compared with general toothpaste. Moreover, the application of white toothpaste did not cause any microhardness reduction on enamel surface.

Appearance management through hair beauty forms the basis of the beauty industry, while permanent waves using heat are often used in hair salons, but hair damage due to thermal permanent wave treatment is an inevitable reality. Therefore, this study was conducted for the purpose of presenting an efficient method for thermal permanent wave that can further increase hair wave formation ability and minimize customer's hair damage. After collecting virgin hair from the occipital region, thermal rod pretreatment and thermal permanent wave treatment were performed, and hair roughness analysis and 3D-image were studied using an Atomic Force Microscope. As a result of the study, both the average roughness (Ra) and the ten point average roughness (Rz) were calculated as 223 nm and 853 nm for 4 sections, respectively, showing the highest values. Although the number of samples of the experimental data is limited, the wave forming power can be further increased through this study, and it is expected that it will be practically possible to propose an objective method for thermal permanent wave that can minimize hair damage as well as protect the cuticle of the customer's hair.Judge.

A 5-year-old, female Poodle and her daughter, 2-year-old, were referred to Konkuk University Veterinary Teaching Hospital (KVTH) due to discoloration of hair on dorsum, and generalized alopecia following clipping. Some papules and pustules are found on patch area. Complete blood counts and serum chemistry profiles were not remarkable. Trichogram revealed that melanin-granule was pigmented on hair bulb and shaft in affected area and no melanin pigmentation was noted in non-patch area. And skin biopsy showed mild epidermal hyperplasia and mild inflammation in dermis of the patch area. This case report indicates that melanotrichia can be occurred by postclipping inflammation. However, the mechanism of melanocyte proliferation and rates of melanogenesis in response to postclipping remains to be unclear in these cases.
