Development of a School-Based Online Periodontal Education Programme for Adolescents.

Introduction And Aims: This study aimed to investigate the effects of a developed school-based online health education programme with a periodontal examination results sheet for high school students on their subjective oral symptoms, knowledge and attitudes regarding oral health, and oral health behaviours.

Methods: The participants were first- and second-year students aged 15 to 17 years (n = 847) at a high school in Japan. The students underwent a periodontal examination and were divided into periodontal condition (PC) and nonperiodontal condition (non-PC) groups.

Current status and factors of periodontal disease among Japanese high school students: a cross-sectional study.

Introduction: This study aimed to investigate the prevalence of periodontal disease and the factors of the disease among high school students.

Method: The participants were all students aged 15-18 years (n = 1202) at a high school in Japan. The data on oral health perceptions and behaviours were collected by a questionnaire survey.

Dental pulp stem cells as a therapy for congenital entero-neuropathy.

Hirschsprung's disease is a congenital entero-neuropathy that causes chronic constipation and intestinal obstruction. New treatments for entero-neuropathy are needed because current surgical strategies have limitations5. Entero-neuropathy results from enteric nervous system dysfunction due to incomplete colonization of the distal intestine by neural crest-derived cells.

Inhibition of Alk signaling promotes the induction of human salivary-gland-derived organoids.

Hyposalivation and xerostomia are the cause of several morbidities, such as dental caries, painful mucositis, oral fungal infections, sialadenitis and dysphagia. For these reasons, preservation of normal saliva secretion is critical for the maintenance of functionally normal oral homeostasis and for keeping good health. Several strategies for restoring salivary gland function have been reported, from different points of view, based on the use of salivary-gland-derived epithelial stem/progenitor cells and tissue engineering approaches to induce organoids that mimic salivary glands.

The 2020 International Alliance for the Control of Scabies Consensus Criteria for the Diagnosis of Scabies.

Background: Scabies is a common parasitic skin condition that causes considerable morbidity globally. Clinical and epidemiological research for scabies has been limited by a lack of standardization of diagnostic methods.

Objectives: To develop consensus criteria for the diagnosis of common scabies that could be implemented in a variety of settings.
