Patient's Query

Hello doctor,

I have an accident history which leads to the fixation of FPD in the place of incisors with the support of two adjacent teeth on either side. Recently I got an infection above one of the supporting teeth. RCT has already done on that tooth. I got my x-ray done. I am having a throbbing pain. Currently, I am taking TAXIM OZ (Cefixime 200 mg and Ornidazole 500 mg) one tablet twice a day, Diclomol SP (Diclofenac 50 mg and Serratiopeptidase 10mg) one tablet twice a day and ketorol DT 10 mg (Ketorolac 10 mg) two tablets thrice a day. Kindly suggest.

Welcome to icliniq.com.

I have gone through your history and OPG (orthopantomogram). (attachment removed to protect patient identity).

There is a periapical (surrounding apex of tooth root) infection. I could see two radiolucent lines near the upper third and apex of root, which could possibly be the cause of infection. We need to take a periapical radiograph (IOPA) of that particular tooth as OPG is not showing finer details. When was the root canal done? If it was done very recently, then continue with the antibiotics, it will help to eradicate the infection. Do you have swelling? Do you have pain while biting in that tooth? Kindly reduce Ketorolac dosage. You can take one tablet in the morning and one at night. In between for pain, take Paracetamol. But, continue antibiotics. As once the infection subsides, the pain will go off too. If you have acidity, take Pantop (Pantoprazole) 40 mg, once at night 20 minutes to half an hour before taking food.

The Probable causes

Apical root fracture or caries near the upper third of the root.

Investigations to be done

IOPA of 12.

Probable diagnosis

Periapical abscess due to fracture or secondary caries. Missing 13.

Same symptoms don't mean you have the same problem. Consult a doctor now!
