Our review on the treatment of post-extraction bleeding has been updated, but there is still no evidence on the topic from randomized controlled trials…
After tooth extraction, it is normal for the area to bleed and then clot, generally within a few minutes. It is abnormal if bleeding continues without clot formation, or lasts beyond 8 to 12 hours; this is known as post-extraction bleeding (PEB). Such bleeding incidents can cause distress for patients, who might need emergency dental consultations and interventions. The causes of PEB can be local, a systemic disease, or a medication. To control this bleeding, many local and systemic methods have been practised, based on the clinician’s expertise. To inform clinicians about the best treatment, evidence is needed from studies where people have been randomly allocated to one of at least two different groups, which receive different treatments, or no treatment (i.e. ‘randomised controlled trials’ or RCTs).

13-17 November is World Antibiotic Awareness Week. The World Health Organization (WHO) has said that antibiotic resistance is: “one of the biggest threats to global health, food security, and development today”. Antibiotics are used to prevent and treat bacterial infections, but if over-used they can cause bacteria to change and become resistant. This makes infections more difficult to treat, and results in longer hospital stays, higher medical costs and increased mortality (World Health Organization, 2017).
Antibiotics are still commonly used in dentistry, Cope et al (2014) estimate that 8-10% of antibiotics used in primary care are prescribed by dentists in some parts of the world. Their effectiveness has been explored by several Cochrane Oral Health reviews over the years, looking at some of the scenarios where they might be prescribed. Today we have a look back over the evidence… Continue reading
Oral leukoplakia is a white patch formed in the mouth lining that cannot be rubbed off. It often does not hurt and may go unnoticed for years. People with leukoplakia develop oral cancer more often than people without it. Preventing this is critical; rates of oral cancer survival longer than five years after diagnosis are low. Drugs, surgery and other therapies have been tried for treatment of oral leukoplakia. Medical and complementary treatments can be locally applied (i.e. directly onto the white patch) or systemic (affecting the whole body, e.g. taken as a pill). Continue reading
Last month we had a meeting of our international editorial team to discuss the new title applications we had received over the last 6 months. We had a lot of applications, and unfortunately were not able to register all of them. We decided that five titles should go forward to protocol stage, from teams in India, Malaysia, and a team based in Germany, the UK and Yemen.
Look out for the protocols coming soon on the Cochrane Library!
People receiving treatment for cancer are at risk of developing a sore mouth and ulcers as a side effect. This side effect is called oral mucositis and affects over 75% of high-risk patients (those receiving radiotherapy to the head and neck or high-dose chemotherapy). The pain caused by this condition can be severe and can stop the person’s ability to eat and drink, which may mean they need to take strong pain killers, stay in hospital and be fed through a tube into their stomach, or even into their veins. This in turn can lead to disruption to their cancer treatment, meaning they are not receiving the best possible treatment. The results may be a reduction in the patient’s chances of survival, and increased costs to the healthcare system. Cancer patients have weakened immune systems due to their treatment, meaning that their bodies are less able to fight infections. This can be a problem if bacteria enter the body through the ulcer, which is an open wound. This can lead to sepsis (a dangerous inflammatory reaction of the body to infection), which requires antibiotics and hospitalisation, and can cause death.
Oral cryotherapy is the cooling of the mouth using ice, ice-cold water, ice cream or ice lollies/popsicles. It is thought to help prevent oral mucositis in people receiving certain types of chemotherapy because the coldness makes the blood vessels in the mouth narrower, and this reduces the amount of blood containing chemotherapy drugs from reaching the mouth and causing oral mucositis. It is a low-cost, natural treatment without serious side effects. Continue reading
