Root Amputation
Dr. Teeth 5 December, 2007
(2) Comment
This tooth had been retreated once, and was failing to heal. Over time, an increase in the radio lucent lesion around the MB root was detected. The patient was then presented the options:
1. Root canal surgery to treat the MB root
2. Extraction & tooth replacement
Since the crown was in good shape, the patient wanted to try and save the tooth. The patient was informed that we would surgically expose the tooth, evaluated the root end. If no fractures are found, then we would recontour the root end (apical resection) and then place a reverse filling (retrofilling) in the end of the root. Patient was also informed if a crack is found down the length of the root, we’ll have to review other options.

Ultrasonic Irrigation
Dr. Teeth 5 December, 2007
(0) Comment During endodontic treatment, our goal is to remove all pulpal tissue and micro-organisms, by-products from within the root canal system. We know that the root canal system is not only made up of the main canal, but may have isthmuses, fins, webs, anastomoses & other irregularities. These variations in the canal shape are impossible to cleanse mechanically. We must rely on our irrigant to reach the places that our files cannot reach. Opening the canals to a large enough size for the irrigant to reach the apex is an important step. I also like to use what I call “ultrasonic stirring”. I use an ultrasonic instrument to “stir” or “vibrate” the irrigant as it sits in the canal. Below is a little video clip showing how I do this.

Dental Pulp Tissue
Dr. Teeth 27 November, 2007
(2) Comment 
This is neat image of a vital dental pulp. The tooth was diagnosed with irreversible pulpitis, acute apical periodontitis and cracked tooth syndrome. RCT was completed prior to crowning the tooth. Once in a while, the pulp will come out in one piece. This actually shows the tissue from the pulp chamber all the way down to the apical portion.

Vertical Root Fracture
Dr. Teeth 27 November, 2007
(0) Comment Vertical root fracture (VRF) can be one of the most challenging parts of endodontic diagnosis. It is often only diagnosed after you have ruled out everything else.
Since treatment of a VRF is extraction, it is important to have an accurate diagnosis. The most certain way to diagnose a vertical root fracture is to see it. This is easily done with a microscope internally. However, that takes significant chair time.
Here are a few tricks that will help you diagnose a VRF.
RADIOGRAPHS:
Look closely at this radiograph. You can see a dark line running parallel to the canal. This dark line will appear if the fracture has caused the root to separate or if you just get lucky with the horizontal angle of your radiograph (just make sure it is not a missed canal).

Endodontist
Dr. Teeth 25 November, 2007
(0) Comment Advancing technologies leads to specialization and super specialization. One such specialization of Dentistry if the field of Endodontics.
Originating from the latin word “ENDO” which means inside and “ODONT” which means the tooth, the science of Endodontics is the study of the problems inside the tooth and an ENDODONTIST is the specialist who treats the inside of the tooth. The outermost layer of a tooth is the Enamel which covers the Dentine. In the core of the tooth is the pulp which has blood vessels supplying nutrients to the tooth and a nerve which provides the sensations. These enter the tooth from the apex of the root and curve up to the pulp chamber which is literally in the centre of the crown.
