Hello, I went to have a cleaning at my dentists and she said I "technically have gum disease (gingivitis)" on one or two of my teeth. They are the last teeth at the back of my mouth on the top and bottom, and they are a bit tender. She said to make sure I brush and floss twice a day, along with using a mouthwash, and I plan on doing so religiously. My dentist didn't say, and I have looked on the internet for an answer, but I can't seem to find a concrete one: how long does it usually take for the gums to stop being inflamed, and the general symptoms of gingivitis to go away? Thanks. 64.229.155.218 ( talk) 04:21, 17 August 2013 (UTC) |
What's the meaning of the numbers in the 1st line of a particular sequence, like in the following example ?

I recently (August 12, 2013) posted a question on engine braking and got satisfactory answers, thanks to all who responded. Well I soon realized it provoked a new question: why is it needed at all? The negative aspects are obvious: a lot of noise, no additional energy is returned to the battery (a parasitic effect as someone, perhaps SteveBaker, said), why not to use simple mechanical brakes we all have in our cars?

How can I use engine braking in my small Honda sedan?

I was up at a cottage (in Central Ontario) for the last week and, while there, I spent some time watching the dragonflies. At one point I saw some odd behaviour. Two fairly large dragonflies (I'm guessing common hawkers, but I'm no expert) were performing what I assumed was a mating flight, riding piggyback intermittently along the edge of a small lake (however, this indicates it's not nearly so straightforward as I thought). Afterwards, one of them began dipping itself into the water, but it was not dipping the tip of the abdomen, where any eggs would come out, but rather the thorax/legs area. It touched the water surface like so, then flew on a few inches and repeated, again and again for at least a few minutes. The abdomen was kept fairly stiff and definitely up out of the water. It was not hurt or having trouble flying (and there was a lot of vegetation it could have landed on if it was having trouble) and it performed at least a few dozen of these dip maneuvers before it flew off. It seemed to be aiming for open areas of water rather than tight against the water lilies. What was going on here? Dragonflies are (AFAIK) purely flight-based predators as adults, so it was not likely hunting anything. Given the fish population it was quite risky behaviour to engage in, so I'm assuming there's some reason behind it? Matt Deres ( talk) 21:19, 17 August 2013 (UTC)
