I have gingivitis. my dentist suggests scaling. which one is better for me(i'm 21) : manual scaling or scaling with ultrasonic instrument? thank you.

Either or both: Most analyses report that patient preference can be the guide since each method is effective. Some mention using a combination to optimize the benefits of each. Using the ultrasonic first and finishing up particular areas manually. There is a few who find that manual techniques leave a smoother finish on the roots and that is good. I expect a dentist to reply too, but till then i hope this helps.

Scaling & root plane: Scaling and root planing is a combination of hand instrumentation and ultrasonic scaling. This, along with improve oral hygiene is the key to your treatment!

Both: Depending on the amount of built-up you might need both treatment done at the same time. Normally they use ultrasonic first and then finish with hand scaling.

Both: The initial phase of therapy normally includes ultrasonic use and then further refined scaling with hand instruments.

Ultrasonic vs manual: Either one can be effective or ineffective based more on the skill and diligence of the operator than on anything else. Personally i find some areas easier to scale with an ultrasonic scaler while other areas easier to use hand instruments. My dental hygienist uses both routinely. Scientific studies show no significant effective difference between the two. Some patients prefer hand instruments.

what do you want?: It depends on you, make sure hand scale instruments are sharpened, and if calculus/ tartar is too tenacious, you may want the ultrasonic, it all depends on what you want, both are effective.

I use both: I like to start with the ultrasonic. It removes the larger tartar pieces and is an excellent irrigator. I will then use hand instruments to remove the remaining plaque and tartar.

Better?: You decide:both hand tools and ultrasonics are tools to remove plaque and calculus ("tartar") from the teeth. Ultrasonics, when used properly can remove the debris and have the potential to disrupt bacterial cell walls near the vibrating tip--and do very little damage to the tooth. Hand work uses a blade to physically scrape the tooth. No bacterial side effects; possible abrasion damage to roots?

Your comfort: Both hand scaling instruments and ultrasonic scaling are very effective with a competent hygienist. Since you are only 21, it is not common for you to need deep scaling and root planning. This is a procedure for the treatment of periodontitis or gum disease. Be sure if you are being recommended more than a superficial scaling, that you have been diagnosed with gum disease. Pockets over 4mm deep.
