[Delirium is defined as a disturbance of consciousness and cognition that develops over a short period of time and fluctuates over time. During the last decade, the number of publications dealing with different aspects of delirium have been grown. The key points in most articles are pharmacological prevention and treatment, but because the rise of health care expenditures, all activities, which cost-effectively support the care process, is getting more and more important. The aim of the study: The aim of this research is to review the non-pharmacological prevention and treatment possibilities of delirium in elderly patients undergoing hip surgery. Systematic review, using articles published between 1999 and 2019 in PubMed and Wiley Online Libraries. Non-pharmacologic treatments significantly reduced the incidence (p=0.003–0.045) and duration (p=0.009–0.03) of delirium. The interventions also contributed to decrease the number of episodes (p=0.03), and to make the symptoms lighter. Early mobilisation and adequate fluid and electrolyte intake are key factors in reducing the incidence of delirium. Measuring oxygen saturation and support, appropriate nutrition, effective pain treatment, minimizing drug-interactions, maintaining good sleep and managing sensory dysfunctions have an effect on incidence, duration and severity of delirium.]

[The use of fluorides is one of the most important areas of dental prevention. It has many beneficial effects on teeth, and it is worth using them starting from childhood. It has an important role in caries prevention and in ensuring the strength of the enamel. However, we must pay attention to take fluoride into our body in moderation. If we don’t act accordingly, we can damage the condition of the teeth and the structure of the bones, to which we should pay special attention during childhood. Fluorosis can be prevented by attention, but adequate information is essential for this, which can be provided by both dentists and dental hygienists.]

[In addition to the joyful nature of pregnancy, this condition uses a great drain to the organization of women, and the oral cavity and teeth are no exceptions. Neglected teething poses several dangers not only to the mother, but to the embryo as well. The mother may develop bleeding gums, inflammation, tooth decay among other problems, and in the foetus may have dental malformations, infection, premature birth or even miscarriage. Researches have shown that pregnant women who are more often attended to dental screening brought a newborn baby into the world with higher weight and the chances of the perinatal complications were on a lower level than those women who were rarely or not tested at all. For this reason, it is an important issue to acutely look after the dental check during pregnancy, not only in dental care but all levels of health care and by almost all professionals with whom the pregnant one meets during that nine months.]

[The incidence of oral cavity tumors is showing an increasing trend, with cause including harmful behaviors, improper nutrition, and inadequate lifestyle. There are many known pre-cancerous conditions, the early diagnosis and treatment of which can prevent malignant degeneration. This is only possible if people conciously pay attention to their oral hygiene and do not neglect regular dental chech-ups. It is important to draw the attention of lay people to this issue in all areas of healthcare.]

[Drug use is still on the rise today, with designer drugs being particularly dangerous. In addition to the general effects on the body, we must also mention the negative effects on the oral cavity. Many people do not realise that oral health can also be at risk, although oral lesions can develop as a result of poor oral hygiene, infections or neurological symptoms caused by the way in which the drug is used, or even by the way in which it is taken. In addition to dental caries, it is important to mention oral infections, tooth wear, or even Kaposi’s sarcoma due to possible HIV infection. Recognition of these oral lesions and of illegal drug use is not only a task for dental professionals, but also for the whole health care system.]
