My parents are both diabetic and our dentist told us about the limitation of dental treatment for them. I came to know from you that BIRDEM has dental outdoor facilities.
Please let me know about the limitation or special measures. We live in Mymensingh.
Yes it is safe to do all kinds of orodental procedures on well-controlled diabetic patients. We usually take extra care for aseptic (Germ free environment) conditions during dental procedures for diabetic patients and prescribe antibiotics. This is simply to prevent secondary infection. But there are some limitations that we take during the surgical procedure (Dental extraction, minor oral surgery etc) of diabetic patient. Sometimes we need to take special measures.
Yes we have modern dental outdoor facilities at BIRDEM (4th floor).
Dear Dr. Khan
Dear Mr. Mahtab,
Hello Dr. Khan
Dear Mr. Ali,
Dear Dr. Khan,
I would like to know if she could go for dental surgery if her diabetes is under control. What precautions should we take before her surgery as a diabetic? I think if you answer positively, she maybe convinced to do the surgery here. Otherwise we may need to fly to Dhaka for your treatment.
Dear Mr. Quayum,
Screwdrivers- uses and types
The Philips head is a common screw and screwdriver. Its design reduces blade slippage from the cross-shaped slot and lends itself to driving with a power bit. The conventional screwdriver has a single blade and is used with screws of matching heads.
Battery-powered cordless screwdrivers are now in the market and are very helpful tools.
Screw heads are usually flat, oval or round, and each has a specific purpose for final seating and appearance.
Flat heads are always countersunk or rest flush with the surface.
Oval heads permit countersinking, but the head protrudes somewhat.
Round-headed screws rest on top of the material and are easiest to remove.
Screw types include the wood screw for when stronger joinings than nails are needed, or for when other materials must be fastened to wood. This screw is tapered to help draw the wood together as the screw is inserted.
A sheet metal screw can also be used to fasten metal to wood, as well as metal to metal, plastic or other materials. Sheet metal screws are threaded completely from the point to the head, and the threads are sharper than those of wood screws.
Machine screws are used for joining metal parts, such as hinges to metal doorjambs. These are inserted into tapped (pre-threaded) holes and are sometimes used with washers and nuts.
Lag screws, or square-headed bolts with screw heads, are for heavy holding and are driven in with a wrench rather than a screwdriver.
When choosing screw length, remember that the screw should penetrate 2/3 of the combined thickness of the materials being joined. Consider as well moisture conditions and the make-up of the materials being fastened, to avoid corrosion. Use galvanised or other rust-resistant screws where rust could be a problem.
Tips on screwdriving:
To remove a screw with a damaged slot, another slot can be cut with a hacksaw blade if the head is exposed enough.
A pilot hole (usually 2 sizes smaller than the shank of the screw) should always be made before driving a screw. This is especially crucial in hardwoods or when driving a screw near the end of the board. When working with screws of larger diameter, a pilot hole of the same diameter as the shank of the screw should be drilled into the wood to a depth of 1/3 the length of the screw.
Always keep the screwdriver shank in line with the screw shank. This will avoid damaging the screw slot and pushing the screw out of line.
By The Way
When you're melting something like butter or chocolate over the stove, add a teaspoon of oil to the pan. This will keep the butter or chocolate from burning and bring the item to a consistent melted mixture.
Under A Different Sky
By Iffat Nawaz
I am always scared boredom will slap me all over my face. The fat that collects from every minute of stalling and feeling uninspired…and that fat does cover my face. Often, my face feels heavier, and my neck has to make extra efforts to hold it up…why do I get bored so easily on some days?
When I am away, out travelling, boredom touches me less, like when I am in Dhaka, or some other place that seems as far way. Or maybe boredom touches me just as much but it melts quicker when I am away; the humidity you see, it melts everything, sweat off boredom, sweat it all off. DC has its humidity too, but not here, not inside, not in this office, it's cold in here. My next-door co-worker owns the power of temperature as his room holds the magical controlling device for my office. And he is always hot even in the winter, so we are always freezing here, at least I am, and my boredom is frozen and stuck to my face, and often it feels permanent.
The other night I had a dream that mushrooms were growing on the right side of my face, they were black, with black stems. There were four or five of them, short and stubby and in my dream I was looking at them closely, trying to pluck them out and I couldn't. They felt so real. I woke up feeling a strange imaginary ache tickling my face, I touched it a few times to make sure there was no vegetation growing. Nothing was, except maybe my boredom, and I touched her, I told her I was disappointed at her for scaring me, for visiting me even in my dreams these days.
I have been day dreaming a lot too. But they are not carrying the right zing that usually keeps me entertained. I am not seeing clearly, not always, frozen sticky boredom is making my mind hazy, but I am not lost. I am not searching, I am just bored.
I am not only bored but I am also spoilt. Boredom has spoilt me, it has given me the luxury of time, of slacking off, of staring out the window looking at the river where men and women swim, then dry off on their boats, bright bikinis and speedos flaunting their immodesty, American flags blow childishly as their boats disappear, and I am left to find the next rich person taking time off in the middle of the day to sun and river bathe. And they come one by one, their worry-free souls make me mad, I get jealous, insecure, upset, and I count my worries as I watch them from my office with my spoilt eyes, spoilt brain and boredom slapped face.
But I can never finish, counting my worries that is…there are too many, or too little maybe. But there are a few, and they have existed silently and vocally, raised their heads in different corners of my life, but I love them still. Especially the old worries, they are like old pets that are dead, you get over them, but you do think of them once in a while and then you think of their deaths, and your youth…and I visit their graves during my boredom filled hours, each of my old worries and their worry-free graves, and I reminisce what they were and what they could have become.
But I know to stop as well, I have learnt to get up, run on treadmills on humid hot summer days to sweat harder; I have started climbing rocks, benches, walls and ladders to be shaken up and fall; I am practicing staring at the monitor long enough without staring out; my spoilt boredom and I cannot co-exist, so there will be death…soon…adding another grave to my old worries.
