In this study, we tried to examine the possibility of developing a dental product such as tooth decay prevention and oral hygiene by manufacturing a natural polymer film for oral use. Natural polymer films were prepared from shark byproduct extract (SBE) and gellan gum (GG). As an antibacterial substance, the antibacterial activity of green tea extract against tooth decay-causing bacteria was measured. An film was prepared by adding green tea extract to the composition of SBE and GG. The mechanical, solubility, moisture content and antibacterial function of the prepared film were investigated in detail. Also, the incorporation of GTE into the SBE/GG film improved the physical performance of the film. Increasing the content of GTE improved the antioxidant and antibacterial properties of the film. Formulation of antimicrobial SBE/GG film containing green tea extract was established and these results evidently showed potential for cavity prevention products application.

Xerostomia is defined as the subjective complaint of dry mouth with or without hyposalivation, which is insufficient salivary secretion from salivary gland. Xerostomia can lead to multiple oral symptoms such as dental caries, halitosis, burning mouth syndrome, and oral candidiasis, which can significantly impact the well-being of patients, especially in geriatric patients who may already have compromised health. Clinical findings of xerostomia include decreased salivary flow and alterations in salivary composition. These changes can lead to various oral health problems such as dental caries, periodontitis, swallowing and speaking difficulties, taste disturbances, halitosis, mucosal diseases, and burning mouth syndrome. Recognizing these clinical manifestations is essential for early diagnosis and appropriate management. Although several reasons and risk factors have been suggested for xerostomia such as aging, chemo-radiation therapy, systemic disease, and Sjögren's syndrome, the polypharmacy is recently highlighted especially in elderly patients. Understanding the etiology and risk factors associated with xerostomia is crucial for effective management. To manage xerostomia patients, a multidisciplinary guideline should be established beyond dental care. Through this literature review, we summarized consideration for diagnostic, therapeutic, nursing essentials for the clinical guideline. By addressing the underlying causes and implementing appropriate treatment strategies, healthcare professionals can improve the quality of life for individuals suffering from xerostomia.

Historically, Eagle syndrome is a term that has been used to describe radiating pain in the orofacial region, foreign body sensation, and/or dysphagia due to a unilateral or bilateral elongated styloid process impinging upon the tonsillar region. Because elongated styloid processes-with or without associated Eagle syndrome-can present with various symptoms and radiographic findings, it can be challenging for healthcare practitioners to formulate an accurate diagnosis. Abnormal styloid anatomy can lead to a multitude of symptoms, including chronic orofacial/neck pain, thus masquerading as more commonly diagnosed conditions. In this report, we describe a patient who presented to our department with styloid process elongation and fracture. A careful history, physical examination, and a cone-beam computed tomography (CBCT) investigation led to the diagnosis. The patient was then referred for appropriate care. This case report demonstrates the utilization of CBCT in differentiating a fracture site from a pseudo-joint that might mimic a fracture.

Objectives: This study confirms the current status of visiting oral health-care services for the elderly to draw policy implications for revitalization of the visiting oral health care services in the future. Methods: First, a survey was conducted on health centers about the current status of the elderly visiting oral health-care service and how to revitalize it. Next, the number of oral hygiene services provided to the elderly was checked in the long-term care insurance system. Results: Oral health education (100%) was the most common practice in visiting oral health-care service for the elderly, and the most difficult thing in providing services was the lack of dental hygienists (38.9%). The status of oral health-care services in the long-term care insurance system for elderly revealed that the total number of service claims has been confirmed to be zero since the introduction of the system. Conclusions: Despite the existence of a system that provides elderly visiting oral healthcare services, to revitalize it, the law must be amended to secure a dental hygienist as the main agent of the activity and to further take responsibility for autonomous authority and performance.

Placenta is a special organ that contains many nutrients such as growth factors, minerals, and bioactive peptides. Dipeptides of glycine and leucine are major components of porcine placenta extracts (PPE) that has been used as an alternative of human placenta extracts. In this study, we investigated whether major peptides of PPE, Glycyl-L-Leucine (Gly-Leu), L-Leucyl-Glycine (Leu-Gly), and L-Leucyl-L-Leucine (Leu-Leu), affect skin hydration and elasticity in vitro and in vivo. We found that Gly-Leu and Leu-Gly dipeptides induced the expression of transglutaminase 1 in normal human epidermal keratinocytes (NHEKs) whereas Leu-Leu dipeptides did not. Treatment with Gly-Leu or Leu-Gly significantly increased hyaluronan (HA) synthesis in NHEKs and the upregulation of hyaluronan synthase 2 (HAS2) mRNA level was confirmed. In addition, elastase activity was inhibited in NHEKs treated with Gly-Leu or Leu-Gly dipeptides. Oral administration of Gly-Leu or Leu-Gly dipeptides increased skin hydration and elasticity in UVB-irradiated hairless mice. The significant upregulation of HA in UVB-irradiated hairless mice was observed in response to oral administration of Gly-Leu or Leu-Gly. These results suggest that the major dipeptides of porcine placenta, Gly-Leu and Leu-Gly, are potentially active ingredients for skin moisturization formulations.
