Background and study aims
Dental caries (cavities) is the major threat to dental pulp (the centre part of the tooth) if left untreated, leading to tooth loss. The treatment of teeth with exposed cavities has been a controversial issue with two different points of view: a conservative approach with vital pulp therapy (pulpotomy) (a partial removal of the diseased pulp while keeping the tooth alive with a therapeutic dressing) and the more invasive but reliable approach with root canal therapy. A root canal therapy is a procedure that removes the infected pulp and then fills it with a rubber like material. Studies have found inflammation (swelling) to be confined to the area next to the carious exposure and not extending beyond 2 mm from the exposure site. So, in cases of carious exposure in vital teeth pulpotomy could be considered as an alternative treatment with success rates comparable to root canal treatment over 5 years follow-up using contemporary biologically active capping materials. The advantages of pulpotomy over a root canal include maintaining the sensation in the health pulp in the roots, and more conservative with lower cost. The aim of this clinical study is to assess the outcome of full pulpotomy in symptomatic permanent teeth with carious exposures using a biocompatible material (biodentine), in order to recommend as an alternative treatment method.

Who can participate?
Adults over the age of 18 who attend the post graduate clinics at Faculty of Dentistry at Jordan University of Science and Technology in Jordan.

What does the study involve?
The tooth is tested using cold test and x-rays of the tooth are taken to establish diagnosis. Participants are asked to record their pain score at attendance. The tooth is frozen using local anesthesia and isolated with dental dam as in routine root canal therapy. Partial pulp removal (pulpotomy) is done, a dressing material is placed, and the tooth is restored. Another x-ray is taken. The participant is contacted by phone after two days to score the pain levels. They are then called at six months, 12 months and yearly up to five years for examination of the tooth.

What are the possible benefits and risks of participating?
Participants may benefit from having caries being removed and the tooth will be treated using biocompatible material and will be restored for free. Viability of the pulp in the root will be maintained and the tooth strength is preserved. There is a risk of pain to continue after 2 days, then routine root canal treatment will be performed for no charge. At subsequent follow up if there is signs of failure root canal treatment will be offered as well.

Where is the study run from?
The study is being run by Jordan University of Science and Technology, and takes place in the postgraduate endodontic clinics at the Faculty of Dentistry (Jordan)

When is the study starting and how long is it expected to run for?
September 2015 to October 2021

Scientific titleOutcome of Biodentine™ full pulpotomy in adult permanent teeth with carious exposures
Study objectivesWould Biodentine full pulpotomy be clinically and radiographically successful in symptomatic adult permanent teeth with carious exposure over 1-5 years follow up?
Ethics approval(s)Institutional Review Board Jordan University of science and technology and King Abdullah University Hospital, 21/04/2016, ref: 13/95/2016
Health condition(s) or problem(s) studiedDeep caries, irreversible pulpitis, symptomatic apical periodontitis
InterventionThe following steps are included in this procedure:
1. The carious tooth will be anesthetized using local anesthesia.
2. Full pulpotomy will be performed for the tooth under rubber dam isolation.
3. Biodentine capping material will be placed
4. The tooth will be permanently restored with resin composite or amalgam.
5. Post operative periapical radiograph will be taken

The tooth is tested using cold test and periapical radiograph of the tooth are taken to establish diagnosis. Participants are asked to record their pain score at attendance. The tooth is anesthetized using local anesthesia and isolated with dental dam as in routine root canal therapy. Partial pulp removal (pulpotomy) are done, a dressing material are placed, and the tooth is restored. A radiograph is taken. The participant is contacted by phone after two days to score the pain levels. They are then called at six months, 12 months and yearly up to five years for clinical and radiographic examination of the tooth.
Intervention typeOther
Primary outcome measure1. Clinical success is measured using percussion, palpation, inspection tests of the treated tooth at 6 months, 1 year, 3 years, 5 years post treatment
2. Radiographic success is measured by periapical radiograph at 6 months, 1 year, 3 years, 5 years post treatment
Secondary outcome measuresResolution of symptoms are measured using Visual analogue scale and 0-10 scale at 2 days after treatment.
Overall study start date18/09/2015
