This review compared the survival of mandibular overdentures supported by 1- or 2- implants. Only two small RCTs were identified that suggest no difference between 1- or 2- implants. However only a small number of patients were included in these trials so the evidence is weak and more high quality trials are required.

This large Swedish questionnaire survey conducted on a random sample of patients achieved a high response rate (83%) . Those who had received dental implant supported restorative treatment reported very high levels of satisfaction (94%). However, 31% had experienced implant related complications although only 6% reported that these complications occurred frequently.

This review included 44 studies (25 prospective, 19 retrospective) and suggests that survival rates for tilted and axially dental implants are similar. However the findings should be treated with caution because of the limited quality of the available evidence.

This review of photodynamic therapy (PDT) for oral premalignant lesions only identified a small number of poor quality studies that provide insufficient evidence for the effectiveness of PDT for the management of oral premalignant lesions.

This new review investigated the effect of alcohol on 23 cancer types. They included 572 case-control and cohort studies and using meta-analysis and a dose–response meta-regression model found relative risks for heavy drinkers compared with nondrinkers and occasional drinkers were 5.13 for oral and pharyngeal cancer, 4.95 for oesophageal squamous cell carcinoma, 1.44 for colorectal, 2.65 for laryngeal and 1.61 for breast cancer.

This new update of a Cochrane review only identified 1 study that randomised 174 children but analysed only 63. While there was a reduction in caries in those children with the slow-release fluoride glass bead the study is at high risk of bias and provides insufficient evidence to determine the caries-inhibiting effect of slow-release fluoride glass beads.

Taste disorders can have a impact of health and quality of life. This new Cochrane review identified 9 trials (566 participants) and found some evidence that zinc supplements could improve taste perception in people with idiopathic taste disorders. However the evidence is not of high quality.

Dental erosion is considered to be an increasing problem. However, clear information about the number of people affected is lacking. This review of 22 observational studies suggests that the worldwide prevalence is 30.4% (95%CI 23.8–37.0). However there is considerable heterogeneity between the studies in part related to the number of indices currently being used to measure tooth wear. So the estimate needs to be viewed with caution.

This review compared root fracture rates of metal and fibre root canal posts and found not difference. While 14 studies were included only 7 were randomised trials and all were of low quality so higher quality studies are needed.

Obstructive sleep apnoea-hypopnoea (OSAH) affects 2-7% of adults. This trial compared 3 mandibular advancement devices with no treatment for mild disease and found benefits over the short term for a range of outcomes including Apnoea-Hypopnoea Index, the Epworth Sleepiness Scale and cost-effectiveness.
