Guest guest Posted January 3, 2011 Report Share Posted January 3, 2011 Air passes from your nose through the pharynx, larynx and trachea to reach your lungs silently without producing any sounds because the passages are patent and the air flow is not so fast, however when the air flow increases or the air passages are narrowed; the air starts to cause vibrations of the walls leading to sound production. This explains why you can hear the sound of the air entry when you do physical exercises {because the air velocity increases. The throat and the back of the mouth are muscular structures {not bone or cartilage} and the muscle tone of these muscles keeps them patent. During the day time the muscle tone is good keeping them patent because you are awake so you don't snore. If you have a deformed uvula, which is the visibly dangling protrusion of skin in the back of the throat, there will need to be the help of a doctor in curbing the snoring. The same is true if your snoring comes directly from excessively enlarged adenoids, and or tonsils within the throat area that will continue to block air passages during the sleeping hours.When the airway in the back of the throat narrows from sleeping in a certain position or there are abnormalities in the throat muscles, snoring will result. An excessive amount of throat tissue or nasal tissue makes a person more prone to snoring. hope this helps...... regards pavan From: Vera Lucia <veradentaluk@...>Subject: NEW QS"oremuttualsupportgroup" < >Date: Tuesday, 4 January, 2011, 4:07 AM CAN ANYONE HELP ME WITH THIS QUESTION PLS?

Guest guest Posted January 4, 2011 Report Share Posted January 4, 2011 One disadvantage of using GI as a cement or luting agent is its sensitivity to moisture. In fact, Mojon et al51 suggest that when using GIs, the involved teeth should be protected from contamination from saliva for as long as 15 minutes after mixing. In contrast, the resin-modified GIs (RMGIs) are hydrophilic (water-absorbing). This presents both an advantage and a disadvantage. The advantage is that the material will expand after coming in contact with moisture, filling any marginal gaps. The disadvantage is that this same expansion can cause all-ceramic crowns to fracture. Lastly, it has been suggested that RMGIs are ideal luting agents for patients who have a high caries index. (Fluoride is released from RMGI.)52 Nevertheless, it might be difficult or impossible to remove a post cemented with this material.

Guest guest Posted February 13, 2011 Report Share Posted February 13, 2011 yes the answer is C ... i found the following information from google books Battle's Sign Battle's sign is a haematoma overlying the mastoid process, which indicates an underlying basilar skull fracture which extends into the mastoid portion of the temporal bone. It appears 48-72 hours after the trauma and some books say 24 -36 hours after trauma Battle's sign is the classic sign of trauma, more specifically of a basilar skull fracture with bleeding into the middle fossa.

Guest guest Posted May 22, 2011 Report Share Posted May 22, 2011 thanks Lee I did not know the biochem part of Xylitol. From: Dr Avery <avery_dr@...> Sent: Sat, May 21, 2011 4:48:18 AMSubject: Re: new qs 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.Lee From: Dr Avery <avery_dr@...>Subject: new qs Date: Thursday, 19 May, 2011, 7:01 Hi guys My question is Which one(s) of the following are beneficial effects of xylitol gum? 1.
