Abstract:
Molar distalization is a frequently used non-extraction option for orthodontic camulflage. Extraoral appliances such as headgear, and intraoral appliances such as pendulums, have been used and achieved effective results. The effect of extraoral appliances depend on patients’ co-operation, and intraoral appliances can have side effects like distal tipping, rotation and anchorage loss. Therefore, anchorage loss can be resist through skeletal anchorage devices in conjunction with intraoral movers. In addition, clear aligners have become common alternatives under aesthetic and comfort considerations, providing Class II correction with high predictability through continuous distalization. However, molars can only be distalized with adequate bony envelope to house the roots, exceeding which will result in dehiscence, root-resorption and even tooth mobility. The boundaries of molar distalization refers to the posterior alveolar region. To date, there is no universal consensus describing the posterior alveolar regions of the maxilla in the context of molar distalization. We then quantitatively analyzed the influence of vertical growth patterns on retromolar regions of mild skeletal Class II patients through measuring cone-beam computed tomography (CBCT) images of 60 patients with hypo-, hyper- and normo-divergent. After standardized orientating images in Mimics 16.0 software, the available distance between second molar root and inner/outer cortical bone as well as the bone volume of reconstructed slices were measured. The results showed significant differences in the maxilla among three vertical growth patterns. In conclusion, vertical growth patterns affect distalization potential, and the patient with hyperdivergent growth pattern is indicative of less potential for distalization.

Abstract:
Introduction
Patients on the care of the elderly ward often present with complex medical histories resulting in increased risk of oral conditions. To improve patient care oral health training was delivered to ward staff on the Geriatric ward at the Royal London Hospital.
Aims
- Identify areas requiring improvement in relation to meeting the oral health needs of elderly inpatients.
- Improve staff knowledge of oral health conditions and maintaining oral health.
Methods
A patient survey was distributed to inpatients assessing oral hygiene regimes and patient satisfaction with oral health care. A site survey was performed to assess availability of oral health equipment based on Mouth Care Matters guidelines.
Teaching was delivered to Care of the Elderly ward staff on the association between oral and general health, common oral conditions and their potential physical and mental impact. Detailed training on oral hygiene delivery was given.
Pre-and post-training surveys were distributed to attendees to ascertain baseline levels of knowledge and effectiveness of training.

- Knowledge of denture cleaning technique increased from 75% to 84%.
- Ability to identify common oral conditions increased from 38% to 50%.
Conclusion
Training feedback was positive; 100% of participants stated they will change their practice as a result. Further training on identifying common oral conditions has been arranged for ward staff.

Abstract:
Cold atmospheric plasma is an emerging technology, exciting to the biomedical field with applications extending from disinfection, wound healing, and tissue regeneration to blood coagulation and cancer treatment. The competence to produce cold plasma at atmospheric pressure conditions was the foundation for the rapid growth of plasma-related application potential in biomedicine. Plasma consists of a number of a highly energetic mix of charged particles, electric current, UV radiation, and reactive gas species such as reactive oxygen and nitrogen that play an essential role in its biological applications, including cancer therapy. Recently, the potential use of cold atmospheric pressure plasma (CAP) in cancer treatment has increased attention. Especially the selective killing property of tumor cells compared with normal cells has prompted investigators to identify the molecular mechanisms for CAP in cancer treatment. This review summarizes the current knowledge about how CAP triggers intracellular pathways that stimulate growth inhibition or cell death. We also discuss the factors that may contribute to CAP's potential selectivity towards cancerous cells compared to normal ones. In addition, the ability of CAP to activate an immune response is briefly reviewed.
