This review of mouthwash use in patients having fixed banded orthodontic treatment included 15 small studies and suggests that they reduce plaque levels. However the clinical relevance of the findings are uncertain and larger well conducted studies are needed.

This review included 17 studies and 843 patients. A wide range of cytokines/chemokines were assessed but the available evidence is not sufficient to prove that there are distinct differences between patients with aggressive periodontitis and those with chronic periodontitis.

This review looked at surgical approaches for the management of internal derangement of the temporomandibular joint. Seven studies were identified of which 3 were randomised trials. Benefits for some outcomes were found with both open and arthroscopic surgery. However the available evidence is limited.

While this new review has included 28 studies, only 6 were RCTs. They found that submerged dental implants had fewer failures than immediate loaded non-submerged implants. The relative risk of failure for immediately loaded compared to submerged implants = 1.78 (95% CI; 1.12 to 2.83).

This review identified 5 trials reported in 11 publications and found that the chewing of xylitol gum by mothers significantly reduced transmission of mutans streptococci to their children. However the effects on caries were inconsistent.

Thirty six studies were identified for this review of maternal-child transmission rates for mutans streptococci. Rates varied from 52.5% – 84.5% with a meta-analysis finding a cumulative event rate of 0.650 (95% CI; 0.565 to 0.726).

While this review of zirconium restoration included 27 studies, only 5 were RCTs. Furthermore only 4 studies had more than 5 years follow up. Ten studies included fewer than 20 restorations, so while good survival data was presented, the results should be viewed with caution.

This cross-sectional study using secondary data and binary logistic models compared the hypothyroidism prevalence at general medical practice (GMP) level with fluoride levels in the drinking water. A positive association was identified although only a small number of confounders were adjusted for which suggest that further clarification is required.
