Lei Fang, Yu Wang, Xuejun Chen
Hereditary gingival fibromatosis (HGF) is a benign, non-hemorrhagic and fibrous gingival overgrowth that may cover all or part of the teeth. It typically interferes with speech, lip closure and chewing, and can also be a psychological burden that affects the self-esteem of patients. Owing to high genetic heterogeneity, genetic testing to confirm diagnosis is not justified. It is therefore important to identify key signature genes and to understand the molecular mechanisms underlying HGF. The aim of the present study was to determine HGF-related genes and to analyze these genes through bioinformatics methods...

Radiotherapy is a life-saving treatment for head and neck cancers, but almost 100% of patients develop dry mouth (xerostomia) because of radiation-induced damage to their salivary glands. Patients with xerostomia suffer symptoms that severely affect their health as well as physical, social and emotional aspects of their life. The current management of xerostomia is the application of saliva substitutes or systemic delivery of saliva-stimulating cholinergic agents, including pilocarpine, cevimeline or bethanechol tablets...

The sugar replacement compound xylitol has gained increasing attention due to its use in many commercial food products, dental hygiene articles and pharmaceuticals. It can be classified by the origin of the raw material used for the production. The traditional "birch xylitol" is considered a premium product in contrast to xylitol produced from agriculture byproducts such as corn husks or sugar cane straw. Bulk stable isotope analysis (BSIA) as well as compound-specific stable isotope analysis (CSIA) by LC-IRMS for chewing gum extracts was used to determine δ13C isotope signatures for xylitol...

Most of the tools and diagnosis models of Masticatory Efficiency (ME) are not well documented or severely limited to simple image processing approaches. This study presents a novel expert system for ME assessment based on automatic recognition of mixture patterns of masticated two-coloured chewing gums using a combination of computational intelligence and image processing techniques. The hypotheses tested were that the proposed system could accurately relate specimens to the number of chewing cycles, and that it could identify differences between the mixture patterns of edentulous individuals prior and after complete denture treatment...

REVIEW
Kate A Wickham, Lawrence L Spriet
There has been recent interest in the ergogenic effects of caffeine delivered in low doses (~ 200 mg or ~ 3 mg/kg body mass) and administered in forms other than capsules, coffee and sports drinks, including chewing gum, bars, gels, mouth rinses, energy drinks and aerosols. Caffeinated chewing gum is absorbed quicker through the buccal mucosa compared with capsule delivery and absorption in the gut, although total caffeine absorption over time is not different. Rapid absorption may be important in many sporting situations...

Titanium dioxide (TiO2) belongs to the materials that have gained great importance in many applications. In its particulate form (micro- or nanoparticles), it has entered a huge number of consumer products and food-grade TiO2, better known as E171 within the European Union, represents an important food additive. Thus, there is an increasing need for analytical methods able to detect and quantify such particles. In this regard, inductively coupled-mass spectrometry (ICP-MS), in particular single particle ICP-MS (spICP-MS), has gained importance due to its simplicity and ease of use...

Despite the prevalence of caffeine as an ergogenic aid, few studies have examined the use of caffeinated gums, especially during half-time in team sports. The physiological (blood lactate, salivary hormone concentrations) and performance (repeated sprints, cognitive function) effects of consuming caffeine gum during a simulated half-time were examined. Professional academy rugby union players (n=14) completed this double-blind, randomized, counterbalanced study. Following pre-exercise measurements , players chewed a placebo (PL) gum for five min before a standardized warm-up and completing repeated sprint testing (RSSA1)...

PURPOSE: To analyze the influence of increasing the average consumption of sugar-free gum (SFG) in 25 industrialized countries on dental expenditures due to caries by the national health care systems. It was assumed that large cost savings were possible, because the regular consumption of SFG significantly reduces the relative risk of caries and therefore, improves dental health, which reduces expenditures on dental treatments. METHODS: A budget impact analysis (BIA) was performed to model the decrease in the relative risk of caries and the subsequent cost savings for dental care...
