Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purposes of the study to compare partial pulpotomy versus complete pulpotomy in primary molars using three different materials (Formocresol, MTA, Theracal LC) . After 6, 9, 12 and 15 months follow up each case will be evaluated radiographically and clinically. the radiographic criteria to be evaluated are (radiolucency, resorption, widening in periodontal ligament space, Crypt involvement) and clinical criteria are ( pain, tenderness, fistula, abnormal mobility) upon these criteria some recommendations will be made on success and failure rate of each material and each technique.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In children, deep carious lesions represent the most common disease of primary teeth; 42% of children aged 2 to 11 have dental carious lesions in their primary teeth, with an average of 1.6 decayed teeth per child. The most important objective of pediatric dentistry treatment is the preservation of functional primary teeth until natural exfoliation. In the era of conservative dentistry we are now focusing on repair rather than replacement.

Challenges regarding the best treatment modality in primary molars with deep carious lesions that are free of signs or symptoms have continued over the years. Based on a recent systematic review and a new American Academy of Pediatric Dentistry (AAPD) Guideline for vital pulp therapy in primary teeth, indirect pulp therapy (IPT), direct pulp cap (DPC), and pulpotomy are all viable options for treating the pulp in primary teeth with deep carious lesions.

Partial pulpotomy (PP) was originally a means of preserving the remaining coronal and radicular pulp tissues in permanent teeth after a traumatic pulp exposure. In 1982, Cvek introduced this technique for permanent traumatized teeth with complicated crown fracture, which involved removing two mm of pulp and then dressing the non-inflamed pulp with calcium hydroxide. However, according to the new AAPD best practices recommendation, PP is also indicated in young permanent teeth with a carious pulp exposure in which pulpal bleeding can be controlled within several minutes.

Calcium Hydroxide PP of primary molar teeth with deep carious lesions is used in studies conducted by Schroder and Trairatvorakul. Schroder. showed that the clinical-radiographic success rate of primary molar teeth one year after PP was 83 percent; they concluded that PP has the same favorable outcome as cervical formocresol pulpotomy (FP).

If the pulp is diagnosed as normal or as having reversible pulpitis, a new regenerative material is recommended as the dressing material. In comparison with complete pulpotomy (i.e., removal of the entire pulp chamber), PP has several advantages; it causes limited injury to the pulp and limited loss of tooth substances, and this is important for pulpal healing and easier restoration.

Pulpotomy is the pulp treatment most commonly used for primary teeth with a deep carious lesion approaching the pulp. With pulpotomy, a portion of the pulp is removed: the coronal pulp is removed and the radicular pulp is preserved. After treatment, the cavity is filled with a medicament followed by a final restoration.

Formocresol pulpotomy (FCP) was developed in 1932 by Charles A. Sweet.". The original FCP was a three-appointment procedure which has been reduced to a one-appointment procedure; it is still the most common treatment for primary teeth with caries approaching the pulp.

Studies have shown formocresol therapy to have a success rate between 70% and 90%.Histologic results have been variable in contrast to the high clinical success rate. Formocresol is still considered a gold standard by which all new modalities are compared.

MTA is used in pulp capping whether indirect or directly it has the advantage of biocompatibility to the pulp tissues and stimulates the odontoblast for thicker secondary dentine formation without tunnel defects and formation of hydroxyapatite like material to seal the pulp tissues. Although it has slow setting time, discolor the tooth, relatively high cost compared to the gold stander calcium hydroxide.

TheraCal light Cured (LC) is a single paste calcium silicate-based material promoted by the manufacturer for use as a pulp capping agent and as a protective liner for use with restorative materials, cement, or other base materials. The material might be very likable for clinicians because of its ease of handling. According to Alberto Danga in 2009 the cytotoxic effect of resin-based light-cured (Theracal) on human pulp tissue was least when compared to other materials.

There is a lack of evidence in partial pulpotomy treating primary teeth. In this study a Randomized control trial will be performed to have an evidence based answer for treating primary teeth with partial pulpotomy.
