Is there any way to expand a narrow maxillary arch without using an expander?


I have never had anything in my mouth and my teeth are straight, but I have a narrow upper palate. Maybe there's a retainer that can do the job? What are the side effects that can happen if the upper palate is expanded? Any info would greatly be appreciated!
----------

well!!! there's no such retainer that can expand your maxillary arch , usually the arches are expanded either by surgical procedures or by placing implants ...
there is a retainer but it is normally active in children not in adults .
in this case it's better you consult an orthodontist.

what does it mean to have crowding and maxillary anterior flaring?


In normal people terms. I had to go to the dentist and I never asked him what it meant. Apparently is has something to do with me getting braces.
----------

You do not have enough room for your teeth to line up straight and they are crooked.

Maxillary anterior flaring means your upper front teeth stick out (flare) instead of being almost straight up and down. The incisal edges (biting edges) are slanted out too far.  (+ info)

Can invisalign widen/broaden the maxillary and mandibular arches?


I hate my teeth (although many people tell me they look fine) BUT i would like to get them as straight as they can be, and being older now (18) and in university, i don't want the wire and bracket braces. BUT i was wondering if Invisalign will actually broaden my arches as well. Please help!
----------

No.
Invisalign is for Class I malocclusions with mild/moderate spacing or crowding of 1-6mm.
It is NOT for:
1. Teeth with short crowns;
2. Class I malocclusions with greater than 1-6mm spacing or crowding;
3. Class 2 and Class 3 malocclusions.
4. Severely rotated teeth;
5. Open bites;
6. Severely tipped teeth;
7. Closing extraction spaces.
With your sort of problem, braces will be the solution. But hey, it's almost a fashion statement to have them! It shows you care about your appearance.

I have a hard time carving maxillary posterior restorations. Does anyone have any tips? ?


I have a hard time with both amalgam and composite. Any tips would be very helpful.
----------

Follow the contours of the cusps. Make sure you are not just digging in randomly, that will cause you to make incorrect anatomical grooves. You have to keep the carver on the cusp.

Also, I've found that it helps to look at the tooth on the other side to get a visual of what you are going for.   (+ info)

What percentage of maxillary 2nd molars have 2 canals?


Found a facial and a lingual, not sure if I've missed a mb or db.
I saw the pt. as an emergency and only had time to do the pulpectomy. IP with AAP. I've done quite a few upper 2nds but haven't run into any with 2 canals. Like you said, most have 3 or 4 with the extra canal always being the mb2.
I use magnification 2x and 4x loupes with illumination.Usually open with a gates, then hand file to a 15 or 20 to get WL with the rooth ZX. Then do what I can with profile depending on the curves.
This one stuck me as strange though because it was very ovoid facial lingual and the canals (F and L) were very large.I didn't have time to completely search for another canal on the buccal so I placed Pulpdent and closed with cotton + cavit. I have the book somewhere in my basement with anatomy and percentages of different canal configurations, but I don't know where it's packed away.Does the description of the tooth match what you've seen in the 2 canal scenerio?Also the radiographs taken straight on and off angle shows only the single central canal. Thoughts?
----------

A very small percentage of upper 2nd molars have only two canals. You will find four canals in those teeth more often than you would find only two, as a matter of fact I've seen five canals in that tooth about the same amount of time I've seen two. I'm not quite sure what technique you use, but may I suggest possibly using some Mueller Burs or an ultrasonic tip just to make sure that you didn't miss it. There is also a fine explorer you can purchase from Darby Dental that will aid in locating any unlocated canals. You can also place CaOH2 in the chamber in between visits to help with the calcification, if that is the case. My opinion is, if worst comes to worst refer the patient to an endodontist, preferably one that has a microscope. Good Luck.

It sounds to me like this tooth only has two canals based on the fact that you noted large canals and one central canal showing on the radiograph. Obviously I don't know for sure without being able to see the tooth myself. It also helps that you did use your loupes with illumination. Yes, this is typical of the teeth I've seen with only two canals. If I were you I would explore a bit more when the patient returns, just to be sure. Eventually, if there is a third canal, if you use the gates, mueller burs, or ultrasonic tip you will be able to drop the explorer in. Good Luck again, these are always difficult teeth!  (+ info)

My MRI showed a nodule/polyp with its own blood supply in the superior maxillary sinus. Should I be worried?


I am a 47 year old non-smoker in good health. This was found incidentally when doing a brain MRI with contrast. The radiologist called the internist and they scheduled an ENT visit for me because they said I must get in ASAP.
----------

All polyps have a blood supply, all this means is it has be removed and evaluated. You are getting great medical care and you should be pleased that the radiologist was so thorough to refere you to an ENT.

It does need to be evaluated but it sound like you don;t have to worrly about it.  (+ info)

Right Maxillary and left ethmoid retention cyst or polyp formation is noted?


Only professionals) that is from a final report, brain MRI.
is that bad? and any more info. u could give me, thanks.
----------

mucous retention cysts in the sinuses are very common findings, often in people who are having no sinus problems at all. they dont necessarily need treatment, but you should follow up with your doctor because only they know for sure what they were looking for on the scans and what the clinical situation calls for.  (+ info)

The tip of line at the hard palate by the maxillary central incisors, is swollen and sore. What is this called?


it comes and goes now and then. My dad gets it as well sometimes.
you know the line on the palate in the mouth, well the tip of the line, right in between the two front teeth, is sore and a bit swollen, and red.
now what is this?
----------

the papilla
If it is swollen or sore, it is usually from burning it on hot food, or scratching it on harder food.  (+ info)

I was told my ct scan shows a cyst in the maxillary sinus?


My question is this (I'm paranoid), can the person reading the ct tell the difference between a cyst and something worse? I have my appointment with an ent next week but the worry creeps in.
----------

Don't worry, cyst are different from tumors and do show up differently. Cysts are fluid fill sacs whereas tumors are a solid mass. Yes, they can tell the difference but they cannot tell if it is cancer or not. Only a biopsy can do that. If he said a cysts, 99% of all cysts are benign. However, cysts are nasty in that they grow fast. They put pressure on whatever area they're in. This is in the sinus cavity which is not a lot of room so my suggestion to you is to ask your DR if it should be removed. If it does grow, it will give you pain and put a lot of pressure on the sinus cavity. Seriously, I wouldn't worry about it being cancer. Good luck to you. I pray all goes well. Be blessed  (+ info)
