Guest guest Posted May 21, 2011 Report Share Posted May 21, 2011 ANSWER: e. All of the above Xylitol is a 5-carbon ring sugar found in nature (bananas, among other things). It is a normal intermediate in human metabolism, but in Mutans streptococci it causes energy depletion and inhibits glycolysis and ATP synthesis. Studies in Finland involving total substitution of Xylitol for sucrose and xylitol chewing gum studies show up to 85% reduction in dental caries. Use of chewing gum stimulates salivary flow and increases mechanical removal of plaque. Recommendations for caries risk patients call for daily dose of 5-10 gms of xylitol. This is accomplished by 5 sticks of gum or 5-10 pellets. Chewing time is 5 minutes (until flavor is gone). Patients should chew after meals, for snacks and before bed.LeeFrom: Dr Avery <avery_dr@...>Subject: new qs Date: Thursday, 19 May, 2011, 7:01Hi guysMy question is Which one(s) of the following are beneficial effects of xylitol gum? 1.

Guest guest Posted June 8, 2011 Report Share Posted June 8, 2011 HiThis used to be a theory but again in a nerve block ,the LA is injected far away from the region of pus accumulation/infection so logically decreased pH should not have profound effect on the nerve block. Below is a part from American association of endodontics recent publication for reference :"Why Don’t Patients With Irreversible Pulpitis Achieve Pulpal Anesthesia?Endodontic patients who are in pain and have pulpal pathosis have additional anesthetic problems. There are a number of explanations for failure:1. The inferior alveolar nerve block does not always provide profound pulpal anesthesia 2. There is a theory that the lowered pH of inflamed tissue reduces the amount of the base form of anesthetic to penetrate the nerve membrane. Consequently, there is less of the ionized form within the nerve to achieve anesthesia. However, this explanation oflocal influences on the anesthetic solution does not explain the mandibular molar with pulpitis, which is not readily blocked by an inferior alveolar injection administered at some distance from the area of inflammation. Therefore, it is difficult to correlate localpH changes with failure of the inferior alveolar nerve block.3. Nerves arising from inflamed tissue have altered resting potentials and decreased excitability thresholds (45,46). Therefore, local anesthetic agents do not prevent impulse transmission due to these lowered excitability thresholds."Sounds logical to me as theories in dentistry keep changing over time ...as we recently discovered with Endocarditis prophylaxis !Looking forward to your thoughts....
