Despite various study designs and small sample sizes, available data suggest that an intervention that incorporates a theoretical-based model and is designed to target caregivers as early as possible is a promising strategy. Furthermore, there is a need to incorporate a cost-benefit analysis in future studies.

Deficiencies in fruit and vegetable intake have been associated with oral cancer (oral cavity and oropharyngeal). Salivary rinses contain measurable biomarkers including soluble CD44 (solCD44) and total protein, which are known markers of oral cancer risk. This study investigates the effect of nutritional factors on solCD44 and protein levels to evaluate oral cancer risk and survival. We evaluated solCD44 and protein levels from 150 patients with oral and oropharyngeal squamous cell carcinoma and 150 frequency-matched controls. We subsequently characterized the effect of food group consumption and these biomarkers on progression-free survival (PFS) and overall survival (OS). Patients reported eating fewer servings of salad (p = 0.015), while controls reported eating fewer servings of potatoes (p < 0.001). Oral cancer patients who consumed at least one serving per week of green salad were found to have significantly lower CD44 levels than those who ate salad less frequently (mean of log2[solCD44]1.73 versus 2.25, p = 0.014). Patients who consumed at least one serving per week of “salad or other vegetables” had significantly longer PFS (median 43.5 versus 9.1 months, p = 0.003, adjusted hazard ratio (HR) = 0.39 p = 0.014) and OS (median 83.6 versus 10 months, p = 0.008, adjusted HR = 0.04 p = 0.029). These findings suggest that dietary factors, namely greater green salad and vegetable intake, may be associated with lower CD44 levels and better prognosis in oral cancer patients.

AimTo systematically appraise the available evidence on vertical ridge augmentation (VRA) techniques and estimate a treatment‐based ranking on the incidence of complications as well as their clinical effectiveness.Materials and MethodsSearches were conducted in six databases to identify randomized clinical trials comparing VRA techniques up to November 2022. The incidence of complications (primary) and of early, major, surgical and intra‐operative complications, vertical bone gain (VBG), marginal bone loss, need for additional grafting, implant success/survival, and patient‐reported outcome measures (secondary) were chosen as outcomes. Direct and indirect effects and treatment ranking were estimated using Bayesian pair‐wise and network meta‐analysis (NMA) models.ResultsThirty‐two trials (761 participants and 943 defects) were included. Five NMA models involving nine treatment groups were created: onlay, inlay, dense‐polytetrafluoroethylene, expanded‐polytetrafluoroethylene, titanium, resorbable membranes, distraction osteogenesis, tissue expansion and short implants. Compared with short implants, statistically significant higher odds ratios of healing complications were confirmed for all groups except those with resorbable membranes (odds ratio 5.4, 95% credible interval 0.92–29.14). The latter group, however, ranked last in clinical VBG.ConclusionsVRA techniques achieving greater VBG are also associated with higher incidence of healing complications. Guided bone regeneration techniques using non‐resorbable membranes yield the most favourable results in relation to VBG and complications.
