Dr. Dinyarian was very knowledgeable, personable, and an excellent surgeon. She explained the procedure in layman's terms. She did the same thing explaining what she observed on my x rays. She was excellent providing the numbing agent into my gums. She did so well that I didn't notice that she had inserted the needle into my gums. She administered the correct amount of anesthetic. No need to do additional shots into my gums to numb the area. I recommend her to anyone searching for a root canal procedure.
