Summary of "The ability of pulp sensibility tests to evaluate the pulp status in primary teeth."

International Journal of Paediatric Dentistry 2011 Background.  Accurate determination of the pulp status is the most important part of conservative pulp therapy. Aim.  The aim of this study was to assess the ability of thermal and electrical pulp tests to assess the pulp status in primary teeth. Design.  Seventy-eight primary molar teeth in 36 children were investigated. Fifty-six teeth had unknown pulp status in need of endodontic treatment, and 22 were intact teeth with no signs of pulp disease. Cold, hot and electrical pulp testing (EPT) were performed on each tooth. The gold standard was established by direct inspection of the pulp after an access cavity had been made. The sensitivity, specificity, positive and negative predictive values for each test and different sequential combinations of pulp testing were calculated. Sequential combination test analysis was used for data analysis. Results.  The highest accuracy was found for EPT, followed by heat and cold tests. No significant difference was found between the accuracy of EPT and the heat test (P-values > 0.05); however, the accuracy of EPT was significantly higher than that of the cold test (P-value < 0.05). Conclusion.  Based on this study, EPT can be used as a reliable test for diagnosing the pulp status in primary teeth.

Medical and Biotech [MESH] Definitions

A dental specialty concerned with the maintenance of the dental pulp in a state of health and the treatment of the pulp cavity (pulp chamber and pulp canal).

Application of a protective agent to an exposed pulp (direct capping) or the remaining thin layer of dentin over a nearly exposed pulp (indirect capping) in order to allow the pulp to recover and maintain its normal vitality and function.

Death of pulp tissue with or without bacterial invasion. When the necrosis is due to ischemia with superimposed bacterial infection, it is referred to as pulp gangrene. When the necrosis is non-bacterial in origin, it is called pulp mummification.

The space in a tooth bounded by the dentin and containing the dental pulp. The portion of the cavity within the crown of the tooth is the pulp chamber; the portion within the root is the pulp canal or root canal.

The destruction of the vitality of the pulp of the tooth. (From Jablonski, Dictionary of Dentistry, 1992, p243)
