Purpose: The inverted nipple presents many problems in both cosmetic and functional aspects. The histopathologic features of inverted nipple are that inverted nipple has less fibromuscular tissue than normal nipple, short lactiferous duct and dense fibrous tissue. Many papers have been reported for correction of the inverted nipple, however not many medical literatures has specifically described about traction method. Although traditional traction methods were using half of urine cup or lid of bottle, they were uncomfortable and incapable for wearing brassiere. Methods: We invented a simple and more natural method using a dome-shape plastic disposable lid of take-out cup. We applied new device for three patients after corrective surgery. Results: For long term follow up, all patients satisfied their postoperative status and they were comportable with the lids. Conclusion: This new method is very simple, comfortable, and effective method for traction. It also allows patients to wear the brassiere.

A commercial propolis was investigated in terms of its antioxidant, antimicrobial, and antiproliferative activities. The contents of total phenol and flavonoid of propolis were 8.3 and 6.6 mg, respectively. The reducing power of the propolis increased with concentration increasing. 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was shown at 82.70% in 1,000 ${\mu}g/mL$ of the propolis. 2,2'-Azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging effect of antioxidant activity on the propolis was 35.64 g/sample. The propolis showed high antimicrobial activity against Bacillus cereus at all concentration of propolis. All of the cancer cell lines have 53-73% as effective growth inhibition. These results showed that the commercial propolis has potential antioxidant, antimicrobial, and cancer cell proliferative inhibition activities thus, propolis can be applied to the functional food, pharmaceutical, and cosmetic industry.

Among the classification of maxillary fracture, the Le Fort classification is the best-known categorization. Le Fort (1901) completed experiments that determined the maxilla areas of structural weakness which he designated as the "lines of weakness". According to these results, there are three basic fracture line patterns (transverse, pyramidal and craniofacial disjunction). A transverse fracture is a Le Fort I fracture that is above the level of the apices of the maxillary teeth section, including the entire alveolar process of the maxilla, vault of the palate and inferior ends of the pterygoid processes in a single block from the upper craniofacial skeleton. Le Fort fractures result in both a cosmetic and a functional deficit if treated inappropriately. In this article, authors review the management of a Le Fort I fracture with a case-based discussion.

In-mold coating is a reactive fluid designed to improve the surface quality of injection molded thermoplastic substrate in functional and cosmetic properties. In this study, a mixing head for in-mold coating was designed, and mixing characteristics of two-component polyurethane flowing through runner were investigated based on flow simulations. In order to achieve uniform mixing of two components injected through straight mixing head, an impingement aftermixer was used in runner design. Semi-circular cross-section was better than circular one for runners for uniform mixing. With increasing runner length and flow rate, mixing became more uniform. In addition, the degree of mixing was more improved with decreasing viscosity of isocyanate.

Botulinum toxin type A (BTX-A), a potent neurotoxin that reversibly blocks presynaptic acetylcholine release, has been applied successfully to treat facial spastic conditions such as blepharospasm, strabismus and cervical dystonia. Since the first reported application in dentistry in 1994, BTX-A has been used with great success to used in the orofacial region to help treat masticatory and facial muscle spasm, severe bruxism, facial tics, and hypertrophy of the masticatory muscles. The clinician may be aware of the many courses becoming available and aimed at dentists to start using it in the cosmetic context. This article intends to provide a basic understanding of the many functional uses of the drug in the orofacial region that may be relevant to everyday practice, especially in orthodontic field.

Successful osseo-integration of dental implants that Dr. Bronemak reported in 1965 had been ground-breaking research in the restorative dentistry for the missing dentition. Clinical application of dental implants in the restorative dentistry has begun with the role of retention and support for the complete denture, beyond the functional recovery in partially missing area, and succeeds in the cosmetic recovery for anterior missing area. Recently, immediate implantation and loading after the extraction have been preferred by many excellent clinicians especially on maxillary anterior missing area, because they want to prevent from the absorption of residual alveolar bone. But it is hard to decide immediate loading for common clinicians also, because it is difficult for them to convict proper osseo-integration. In this article, immediate implantation and delayed loading case on maxillay anterior region have been introduced and predictable prosthetic procedure for the esthetic result has suggested.

In this study, crude extract of the seagrass Zostera japonica, and its solvent-partitioned fractions were evaluated for their antioxidant activity. The crude extract was successively fractionated into n-hexane, 85% aqueous methanol (85% aq.MeOH), n-butanol (n-BuOH), and water fractions by liquid-liquid partition. These include DPPH radical scavenging, hydroxyl radical scavenging in HT-1080 cells, peroxynitrite scavenging, and protective effect on DNA damage caused by hydroxyl radicals generated. In all assays, except for DPPH radical, 85% aq.MeOH and n-BuOH fraction showed the strong antioxidant activity. These results suggest that Z. japonica may be used as a potential source of natural antioxidants for the development of cosmetic product or functional food in the future.

The aim of this study is to utilize the algae extracts with functionalities such as antioxidant and antimicrobial properties for preparing lip balm. Functional properties of extracts from Dictyota coriacea and Ulva pertusa were evaluated in terms of DPPH radical scavenging activity and antimicrobial activity. Lip balms contained the algae extracts were tested its efficacy by measuring the moisture retention of lip skin after applying human subjects. According to the results of skin moisture retention measurement, lip balm was effective to increase the moisture retention of lip skin. It is considered that the utilization of colorants extracted from algae which are verified of antioxidant effect and antimicrobial activity is valuable and useful in developing the cosmetic products.

Advanced cancer of the oral cavity has been treated with wide excision in conjunction with mandibulectomy and neck dissection. This has resulted in significant mandibulofacial defects with functional and cosmetic significance. Therefore, proper mandibular reconstruction is very important for physiologic and esthetic restoration. The risk factors of free flap reconstruction have been reported including obesity, age, smoking, previous irradiation, and systemic vascular disease. We recently experienced a case of donor site necrosis after fibular osteocutaneous free flap in oral cavity cancer.

Segmental mandibulectomy causes severe functional disability and cosmetic problem. Many methods of reconstruction have been used but none of these procedures provides the ideal solution. There has been increased interest in the possibility of preserving a portion of the mandible and still carrying out a adequate tumor resection. We experienced four cases of marginal with sagittal mandibulectomy in patients with floor of mouth. buccal. and soft palate carcinoma, and sagittal mandibulectomy in 8 patients with tonsillar carcinoma and a case of marginal mandibulectomy in tonsillar cancer patient. In all cases mandible facing the tumor were successfully resected and repair of the mandible. postoperative facial contour were satisfactory. We think. that these sagittal procedures are oncologically sound in its removal of tumor. biomechanically secure and maximize postoperative rehabilitation while maintaining the normal contour of the face.
