Brief Summary

Pulpotomy has been proposed in the last decade as a definitive treatment of mature permanent teeth with irreversible pulpitis due to the better understanding of the pulp biology and development of bioactive materials . This technique involves removal of the coronal portion of the pulp that has undergo degenerative and irreversible changes to the level of the canal orifices and leaving the healthy vital radicular portion of the pulp. The surrogate marker for the degree of inflammation and the healing potential of the remaining pulp tissue has been suggested to be the ability to control the bleeding after pulp amputation.

By preserving the pulp vitality, this can help in maintaining proprioceptive, reparative, innervation (tooth sensitivity), vascularization, and damping functions. The vital pulp can continue to serve the function of protecting the tooth from overload by means of protective feedback mechanism and preventing fracture because of the presence of pulp and organic tissue in the dentinal tubules..

Detailed Description

The routine dental treatment for the patient diagnosed with symptomatic or asymptomatic irreversible pulpitis secondary to deep carious lesion is conventional root canal treatment. Root canal treatment is the preferred treatment option because of its superior success rate to other treatments .

However, it is expensive, time consuming and complicated. Root canal treatment needs special clinical skills and high socio-economic status to afford the cost of the treatment. Unfortunately, in developing countries these can be un-reachable. Therefore, extraction is the only alternative option to the affected teeth . Moreover, a recent systematic review by Ng et al stated that the success rate of root canal treatment had not improved over the past few decades and molars had poor survival rates in comparison to non-molar teeth.In addition, It was stated that the survival rate of endodontically treated tooth is alarmingly low in comparison to vital teeth, especially molars, During root canal treatment many mishaps can occur such as perforations, ledges and extrusion of root filling, that reduces the longevity of root treated teeth .

Carious pulp exposure of permanent molars in children is a very common unfortunate event faced in Pediatric Dentistry and Public Health department in Cairo university. This may be due to the low socioeconomic status, ignorance of patients attending that clinic, their wrong eating habits and their bad oral hygiene.

Root canal treatment in an uncooperative young patient is very complicated which may affect the quality and prognosis of the treatment itself. Therefore, an economical, simple and conservative technique such as pulpotomy should be considered Pulpotomy has been proposed in the last decade as a definitive treatment of mature permanent teeth with irreversible pulpitis due to the better understanding of the pulp biology and development of bioactive materials . This technique involves removal of the coronal portion of the pulp that has undergo degenerative and irreversible changes to the level of the canal orifices and leaving the healthy vital radicular portion of the pulp. The surrogate marker for the degree of inflammation and the healing potential of the remaining pulp tissue has been suggested to be the ability to control the bleeding after pulp amputation..

By preserving the pulp vitality, this can help in maintaining proprioceptive, reparative, innervation (tooth sensitivity), vascularization, and damping functions.The vital pulp can continue to serve the function of protecting the tooth from overload by means of protective feedback mechanism and preventing fracture because of the presence of pulp and organic tissue in the dentinal tubules.The dentin -pulp complex will stimulate the formation of tertiary dentine or a mineralized barrier protecting itself .

Compared to the root canal treatment, pulpotomy is considered less technique sensitive so it can be performed by general dental practitioners. Hence, It increases the patients' access to dental care and more clinicians will be able to provide the affordable treatment saving more teeth when the patients cannot afford the root canal treatment leaving extraction as a last treatment option.

It is believed that the pulp tissue of the younger aged patients has higher healing capacity and regenerative powers than pulp tissue in older aged patients.

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

Pulpotomy

Group A (Experimental group) Pulpotomy:

The teeth will be anesthetized with 4% articaine 1:100,000 epinephrine (Artinibsa®; Inibsa Dental, Lliçà de Vall, Spain) by inferior alveolar nerve block.Under rubber dam isolation, pulpotomy will be performed with a large sterile round end bur in a high speed hand piece with copious irrigation; pulp tissue will be removed by a sharp spoon excavator to the orifice level. Hemostasis will be achieved by the application of a wet cotton pellet moistened with 2.5% NaOCL for 2 min and repeated if needed.

After hemostasis, Biodentine (Septodont, Saint Maur des Fausses, France) will be mixed according to the manufacturer's instructions and gently placed over the pulp to thickness of 2-3 mm.Biodentine will be covered by resin modified glass-ionomer and teeth will be restored using composite resin.A postoperative radiograph will be taken by parallel technique.

Group Type: EXPERIMENTAL

Pulpotomy

Intervention Type: PROCEDURE

Pulpotomy is a procedure in which the coronal pulp is amputated, and the remaining radicular pulp tissue is treated with a medicament to preserve the pulp's health .This technique involves administration of local analgesia, Isolation of the tooth with rubber dam, Complete caries removal and then access to the pulp chamber using drills

Root canal treatment

Group B (control group) Root canal treatment:

The teeth were anesthetized with 4% articaine 1:100,000 epinephrine (Artinibsa®; Inibsa Dental, Lliçà de Vall, Spain).Under rubber dam isolation, root canal treatment will be performed in single visit.Working length will be determined using stainless steel k-files (Mani, Inc.) keeping 0.5 to 1.0 mm short of the apex using a RootZX apex locator (J. Morita, Irvine, CA) and confirmed radiographically. Mechanical preparation will be achieved by a crown-down technique using using the M-PRO system (IMD, Shanghai, China) and irrigation with 5 mL 2.5% NaOCl between instruments.Obturation will be done with gutta-percha (Meta Biomed Co. Ltd, Cheongwongun, Chungbuk, Korea) and resin sealer ADseal (Meta Biomed CO., LTD, Korea) using cold lateral condensation technique and restored with composite resin with a base of glass-ionomer cement. A postoperative radiograph will be taken by parallel technique.

Root canal treatment

Intervention Type: PROCEDURE

Root canal treatment is an often straightforward procedure to relieve dental pain and save teeth. Patients typically need a root canal when there is inflammation or infection in the roots of a tooth. During root canal treatment, an endodontist who specializes in such treatment carefully removes the pulp inside the tooth, cleans, disinfects and shapes the root canals, and places a filling to seal the space.
