In the reported literature, the prognosis of direct pulp capping is unpredictable, with the lowest success rate in carious pulp exposures in the adult dentition. Retrospective studies have shown CH pulp capping to have a success rate of 30-85% over a period of 2-10 years (64) (65) (66) (67). "[3][7] However, calcium hydroxide and mineral trioxide aggregate (MTA) are the preferred material of choice in clinical practice due to their favourable outcome. 16. In fact, it may be likely that if you did remove all of the decay, the pulp would be exposed by the infected decay thus resulting in the need for a root canal. Tronstad L, Mjör IA. [ Links ] 8. Results: After 48 months, Group-1 showed a success rate of 88.8% and Group-2 of 93%. [9] In pulp perfusion studies, CaOH has shown to insufficiently seal all dentinal tubules, and presence of tunnel defects (patent communications within reparative dentine connecting pulp and exposure sites) indicate a potential for microleakage when CaOH is used. 2006;31(2):68-71. This is a step wise procedure and a long procedure which takes about 6 months or more to complete. [3] Once the exposure is made, the tooth is isolated from saliva to prevent contamination by use of a dental dam, if it was not already in place. But more recently mineral trioxide aggregate (MTA) used as a primary molar medicament for pulpotomies reported a 97% success rate. Instead, the dentist intentionally leaves the softened dentin/decay in place, and uses a layer of protective temporary material which promotes remineralization of the softened dentin over the pulp and the laying down of new layers of tertiary dentin in the pulp chamber. 11. This method is also called "stepwise caries removal. Alex G. Direct and indirect pulp capping: a brief history, material innovations, and clinical case report. Indirect pulp capping • procedure where the deepest layer of the remaining affected carious dentin is covered with layer of biocompatible material in order to prevent pulpal exposure and further trauma to pulp. Oral Surg Oral Med Oral Pathol. When dental caries is removed from a tooth, all or most of the infected and softened enamel and dentin are removed. [34] Calcium hydroxide has also been tested on its use in indirect pulp capping and was found to have a success rate of 77.6%, compared to a success rate of 85.9% for MTA in another study.[35]. MTA also comes in white and grey preparations[26] which may aid visual identification clinically. Direct pulp capping (DPC) and calcium hydroxide has been widely used with high success rates in young permanent teeth, but the results in primary teeth are less satisfactory [3,4]. Because of its many advantageous properties and long-standing success in clinical use, it has been used as a control material in multiple experiments with pulp capping agents over the years[17][18] and is considered the gold standard dental material for direct pulp capping to date. FACTORS DETERMINING SUCCESS OF IPC. Indirect pulp treatment is a procedure performed in a tooth with a deep carious lesion approximating the pulp but without signs or symptoms of pulp degeneration. [14], CaOH does however have significant disadvantages. [13] This alkaline environment created around the cement has been suggested to give beneficial irritancy to pulpal tissues and stimulates dentine regeneration. A very recent multi-centre RCT of moderate quality observed better success rate for indirect pulp capping than stepwise excavation after an observation period of 3 years, 91% versus 69%. [28][29], There have been several studies conducted on the success rates of direct and indirect pulp capping using a range of different materials. [20] MTA has been shown to produce CaOH as a hydration product[21] and maintains an extended duration of high pH in lab conditions. Grey MTA preparations can potentially cause tooth discolouration. [33] This study was conducted on 6-18 year old patients, while a comparable study conducted on mature permanent teeth found success rates of 84.6% using MTA and 92.3% using Biodentine. Figure 3: The final restoration, in this case resin-based composite, should be placed over the direct or indirect pulp cap in the normal manner as described in this article. Remaining dentin thickness(0.5-2mm) Choice of indirect pulp capping agent. [24] There is also less coronal microleakage of MTA in one experiment comparing it to amalgam[25] thus suggesting some tooth adhesion properties. Pediatr Dent. [5] This is due to Eugenol, being cytotoxic to the pulp are present in large quantity in this formulation. Physiology of the human dental pulp. Studies on indirect pulp capping had clinical success ranging from 73 to 97% after a follow-up period of 2 weeks to 11 years . Results: The success rate of direct capping was 80.1% after 1 … Most importantly, its toxicity to human pulp cells once again makes it an unacceptable material of choice. Clinically and radiographically, teeth treated with indirect pulp capping using MTA show higher success rates after 3 months compared to using a setting calcium salicylate cement (Dycal, Dentsply Sirona, Konstanz, Germany). Objective: A retrospective study of the success rate of direct pulp capping (DPC) and indirect pulp capping (IPC) was carried out in children between 6–14 years-old, con-sidering separately primary caries or caries affecting teeth with molar incisor hypo-mineralization (MIH). This technique is used when most of the decay has been removed from a deep cavity, but some softened dentin and decay remains over the pulp chamber that if removed would expose the pulp and trigger irreversible pulpitis. (1991), bacteria-inoculated root canals of extracted human teeth were treated with CaOH for 1 hour against a control group with no treatment and the results yielded 64-100% reductions in all viable bacteria. [3], Contraindication for Direct Pulp Capping:[4], In 1938, Bodecker introduced the Stepwise Caries Excavation (SWE) Technique for treatment of teeth with deep caries for preservation of Pulp vitality. The tooth is then washed and dried, and the protective material placed, followed finally by a dental restoration which gives a bacteria-tight seal to prevent infection. The difficulty with this technique is estimating how rapid the carious process has been, how much tertiary dentine has been formed and knowing exactly when to stop excavating to avoid pulp exposure.[8]. Zinc Oxide Eugenol (ZOE) is a commonly used material in dentistry. A three-year study of 44 carious exposed pulps capped with calcium hydroxide resulted in an 80% success rate.46 Thirty-four traumatically exposed teeth that experienced an approximately four-hour delay before calcium hydroxide pulp capping demonstrated 97% success when followed for periods of up to 17 years.90 To better elucidate the relative benefits of MTA versus calcium hydroxide for pulp … An Indirect pulp cap is where, in a permanent tooth, most of the decay is removed. Studies have demonstrated that it encourages bleeding due to its vasodilating properties hence impairing polymerisation of the material, affecting its ability to provide a coronal seal when used as a pulp capping agent. Factors affecting the outcomes of direct pulp capping using Biodentine. A systematic review attempted to compare success rates of direct pulp capping and indirect pulp capping and found that indirect pulp capping had a higher level of success but found a low quality of evidence in studies on direct pulp capping. [13][16] It is suggested that an adhesive coronal restoration be used above the CaOH lining to provide adequate coronal seal. [3] A direct pulp cap is a one-stage procedure, whereas a stepwise caries removal is a two-stage procedure over about six months. [23] MTA has also demonstrated reliable and favourable healing outcomes on human teeth when used as a pulp cap on teeth diagnosed as nothing more severe than reversible pulpitis. The set cement has low compressive strength and cannot withstand or support condensation of a restoration. Other studies also support claims of Biodentine’s and MTA’s superiority over calcium hydroxide in terms of success rate in pulp capping procedures [107,108]. This technique is used when a pulpal exposure occurs, either due to caries extending to the pulp chamber, or accidentally, during caries removal. J Clin Pediatr Dent. They had pulp dressing by indirect pulp capping technique.Results: MTA dressing (indirect pulp capping technique) is associated with 55% of the success meanwhile the use of calcium hydroxide is associated with 60% succes rate. Defined as a procedure in which the exposed vital pulp is covered with a protective dressing or base placed directly over the site of exposure in an attempt to preserve the pulp vitality. ... success rate of the ProRoot MTA material was higher than those of TheraCal LC and Dycal (the success rates were 94.4%, 87.8% and 84.6 % respectively). Dentin formation usually starts within 30 days of the pulp capping (there can be a delay in onset of dentin formation if the odontoblasts of the pulp are injured during cavity removal) and is largely completed by 130 days.[2]:491–494.
