The purpose of a RCT is to clean out the pulp cavity of neurotic tissue and then to create a complete seal that will prevent bacteria from entering and leaving the RC. A RCT might be need because of gross caries reaching the RC or leakage of previous RCT or trauma which will lead to loss of vitality resulting in interruption of blood and/or nerve supply.
The RCT can be divided according to the following steps:
1. Preoperative Radiograph
A preoperative radiograph provides the dentist with information regarding the RC obturation and its subsequent analysis. The dentist is able to see how far the blockage of the RCT reaches, allows the dentist to identify RCs orifice and to get an idea on how to negotiate the root canals15.
An example of RC blockage is the appearance of calcification in the RC. Only in rare cases blockages are not identifiable. This location and region of RC blockage allows the dentist to choose the most effective method to remove whatever is blocking the RC so that the RCT can begin, e.g. in order to be able to treat a RC in a maxilla premolar, the access for coronal penetration starts off at the centre of occlusal surface and by following the long axis of tooth.
The orifice of the RC is identified with an explorer as it is pressed where according to the radiograph the orifice is believed to be. If there really is an orifice present, the explorer will slightly dislodge as it is pressed on the blocked orifice. In order to minimise perforation and to reconfirm the orifice’s location, a second radiograph is done with the explorer left in place15.
2. Coronal Preparation/ Access
Before the access to the RC starts, the dentist places a tuber dam – thin latex sheet – with a hole over the tooth to be treated after havi...

...nts new microorganism from entering the RC. Afterwards, a fingerspreader (fine (F) when master file used was <25 and a less finer spreader (MF for master file 30+ in size) is placed into the RC with a downwards pressure and removed by twisting and rotating the spreader towards the wall. This allows the sealent to spread laterally towards the RC walls.
This whole process is repeated until now more GP point scan fit and the whole canal is pink in colours (pink colour of GP point). If the RC is not pink it suggests that there are still gaps left and carried, microorganism or RC might leak. In the end a hot excubator is used to cut the GP points ends that are sticking out of the RC.
But in order to completely seal off the RC a restoration is placed onto the treated RC. This will completely off the RC from the outside environment and prevent wear and abrasion of the RC
When the liquid level is above the calibration line on the pipette, remove the bulb quickly and put your thumb or index finger over the pipette. Carefully “roll” finger to the side and allow the liquid to drop until the meniscus is level with the mark. Then hold the pipette over the flask to receive the liquid and remove the finger. Allow the liquid to drain out.
3-D scanning has helped improve orthodontics a lot with finding the problem and being able to understand the problem better. Also it can help see everything in your mouth that a regular x-ray cannot see.
Radiologic technologists, also known as radiographers, have the job of performing diagnostic imaging examinations; among many other tasks. The typical radiographer must be able to interact with patients by taking their medical history, administering oral or injected contrast media, explaining procedures and safety measures, and observing and monitoring them. Radiologic technologists also have to correctly position and immobilize their patients for examination; along with assisting patients that are unable to move (i.e. disabled, sick, injured patients). If a radiologist finds any abnormalities while handling a patient they must report it to the physician. Along with that, a radiologic technologist must be capable of operating all equipment required for the job including x-ray generators, ultrasound scanners, and fluoroscopes. They must be able to use radiation safety guidelines and proper protection materials to keep everyone (including themselves) safe and comply with government regulations. A radiologic technician has to process and review film and other information to evaluate whether or not it is satisfactory for diagnostic purposes and
3rd: Finishing the procedure after the completion of root canal therapy is one of the most important details. The doctor will shape, clean and fill the effected tooth. The substance they use to do this is similar to rubber, but is a biocompatible material designed for this procedure called
Assessment. Maricela started by taking the patient’s blood pressure, as well as added new medical information to her chart and let the Dentist evaluate her medical history. After that she proceeded with the intra/extra oral exams. Since the patient had dentures, Maricela made sure to pay extra attention to her maxillary hard palate. There was definite signs of irritation, redness, and a few sores from constant rubbing. Next, Maricela did a periodontal assessment. Even though the patient had a lot of tooth loss, her gums were decently healthy. She had a few pockets, but it surprised me how healthy the gums actually were. When documenting caries and dental charting, it was documented that the patient had a low plaque score that did end up being a little higher than the last appointment. No radiographs where
The patient had no changes to her health history and is overall healthy despite vision impairment. After reviewing her probe depths in comparison to her last appointment, it was apparent there was no longer bleeding upon probing in the first quadrant. Her probe depths had also gone down generally by one mm in both quads one and two. The treatment therapies that were performed for this patient at recall included using the ultrasonic throughout all four quads. This patient did not handle the ultra-sonic well, so we took many breaks and touched up with hand scaling. The patient had multiple open contacts, so during patient education I showed her the proxy brush and how to adapt it within the embrasures. I emphasized the importance of flossing and using the proxy brush in regard to decrease the amount of plaque between her teeth and hindering her risk for continued bone loss and interproximal caries. I placed most of this education under the urgency that we would like to maintain the teeth and their surrounding bone structure. The plaque score was still low. I also explained to her the importance of brushing without added pressure and demonstrated the modified Stillmans method to prevent future gingival recession on the lower anteriors. Although the patient hadn’t showed much improvement in regards to homecare, I believe that sometimes hearing it over and over can help advance them up on the learning
In addition, 3D images and/or X-rays may be taken of the mouth. Once this information has been gathered and reviewed, the various implant options available to you will be discussed. If you decide to go ahead with the dental implant procedure, a custom-designed surgical plan will be created for you. On occasion, if X-rays are not able to provide the doctor with the information necessary, a computer tomography (CT) scan may be required. Once all your presurgical testing is complete and your surgical plan has been created, your dental implant procedure can be
In addition, we were asked to come in an identify the number attempts made for the insertion of veress needle per protocol we were off the midline and at a previous laparoscopic incision site and we attempted three times each time with a negative water drop test. Then we moved a little bit more lateral to a new incision site and at this time we attempted one time and were able to successfully place the veress needle and successfully do the water drop which indicated that the veress needle is free within the peritoneal cavity insufflation and place our additional
Stoll, Betke et al. (2005) In a retrospective study estimated that the survival according their apical extent. Flush fillings had a 94% survival estimation while short and long fillings estimated results were 80.9% and 74.0% respectively in 5 to 10 years.(Caplan and Weintraub 1997) in a case control study found similar results but it was insignificant. They also found that teeth which had long fillings were extracted rather than retained in contrast to short filling which were retained more often than extracted. The previous results show that RCT within 2 mm of the radiographic apex have the best outcomes.
Radiology is a part of the health service industry and as a service provider one needs to understand quality and delivery of service, which includes knowledge of customer service, customer satisfaction and all of its related issues [1].
It began as a basic wisdom tooth extraction; the goal was to remove all 4 wisdom teeth. Though the teeth had not yet gone through the gum, I was told it would be a easy procedure. The only warnings I had received, was a risk of hitting the trigeminal nerve, causing pain and tingling, but even

Have you ever had an x-ray taken or perhaps had a sonogram done? If so then you probably met a radiologic technologist. A radiologic technologist is a person that is trained in using x-ray and ultrasound imaging technology as a diagnostic tool or as a part of a patient’s treatment plan. A radiologic technologist creates images of specific areas and parts of the human body which include bones, tissue, blood vessels, and organs. They may also perform such imaging procedures such as mammography, x-rays, sonography, computed tomography (CT), and magnetic resonance imaging (MRI). Radiologic technologists also work under the supervision of radiologists that are trained to read and interpret the medical images that the
Treatment: Smooth sharp edges. If the patient has a lip or cheek lesion, it is advisable to search for tooth fragments or foreign materials.
