Dental pulp testing: a review

Dental pulp testing is a useful and essential diagnostic aid in endodontics. Pulp sensibility tests include thermal and electric tests, which extrapolate pulp health from sensory response. Whilst pulp sensibility tests are the most commonly used in clinical practice, they are not without limitations and shortcomings. Pulp vitality tests attempt to examine the presence of pulp blood flow, as this is viewed as a better measure of true health than sensibility. Laser Doppler flowmetry and pulse oximetry are examples of vitality tests. Whilst the prospect is promising, there are still many practical issues that need to be addressed before vitality tests can replace sensibility tests as the standard clinical pulp diagnostic test. With all pulp tests, the results need to be carefully interpreted and closely scrutinised as false results can lead to misdiagnosis which can then lead to incorrect, inappropriate, or unnecessary treatment.

Evaluation of variability of electric pulp response threshold in molars: an in vivo study

International Journal of Clinical Trials, 2020

Background: Electric pulp testers are widely used diagnostic tools in endodontics. Several factors can affect the result of electric pulp test like thickness of enamel and dentin, concentration of sensory fibres (A delta fibres), direction of dentinal tubules, pulp chamber size, neural elements etc. There are very few studies available in the literature which evaluated the variability of electric pulp response in molar teeth, which are more susceptible to caries. Hence aim of current study was proposed to evaluate response threshold in molars with respect to age and sex using electric pulp tester.Methods: Fifty volunteers aged between 20 to 69 years were recruited. The human subjects were divided into 5 groups of 10 each (5 males and 5 females) based on age. EPT was used with appropriate electrolyte as a conducting media. Seven sites on each molar crown were tested which includes mesiobuccal cusp tip, mesiobuccal cuspal surface, mesiobuccal gingival surface, centre of the supporting...

Evaluation of the Two Commonly Used Pulp Tests for Assessing Pulp Vitality and Sensitivity

Pakistan biomedical journal, 2022

Tests for the dental professional's diagnostic and treatment planning purposes are called dental pulp tests [1]. A diagnosis of the underlying ailment is often made very quickly when pulp testing is combined with information acquired from the patient's medical history, examination, and other tests, such as radiography. As recently as the late 1970s, pulp testing was used in a wide range of clinical dental settings with varying degrees of effectiveness [1]. This might be seen as the ideal diagnostic test has not yet been achieved. In terms of accuracy, reliability and reproducibility in a given diagnostic challenge, all present pulp tests have aws in the technical realm. It is also important to know when to do a pulp test, as not all pulp testing agents are suited for all clinical situations [2, 3]. Thermal and electric pulp sensitivity tests have been performed to examine the pulpal health of teeth by assessing the state of the pulp's nerves [4]. These examinations frequently yield false-positive and false

Electric pulp test threshold responses in healthy incisors, canines, premolars and molars

Australian Endodontic Journal, 2017

The purpose of this study was to determine the range of threshold responses of healthy dental pulps and test the reproducibility of the electric pulp test (EPT). Forty-nine dental students participated in the study. Sound teeth in both arches, except third molars, were included. The teeth were isolated using cotton rolls and dried with compressed air, and the threshold responses were recorded. Participants stopped the stimulus increase by pressing the switch at the first sensation of discomfort. The measurements were repeated after 30 days. The obtained data were analysed using SPSS16.0. The mean thresholds for the maxillary incisors, canines, premolars and molars were 10.77, 21.07, 21.88 and 34.07 lA, and for mandibular incisors, canines, premolars and molars 9.81, 18.7, 19.24 and 30.1 lA respectively. The differences between the two measurements were statistically significant for teeth 32, 31, 41 and 42. The EPT was shown to be reproducible for all the teeth tested except mandibular incisors.

Correlation Between Pulp Sensibility Tests and Histologic Diagnosis

iranian endodontic journal, 2017

The purpose of this study was to assess the accuracy of sensibility tests by correlating it with histologic pulp condition. Methods and Materials: Assessment of clinical signs and symptoms were performed on 65 permanent teeth that were scheduled to be extracted for periodontal, prosthodontic or orthodontic reasons. The normal pulp and reversible pulpitis were considered as treatable tooth conditions while irreversible pulpitis and necrosis were considered as untreatable conditions. The teeth were then extracted and sectioned for histological analysis of dental pulp. Histologic status and classification corresponded to the treatable or untreatable pulp condition. Comparisons between histological treatable and untreatable pulp condition were performed with chi-square analysis for sensibility test responses. The positive predictive value (PPV), negative predictive value (NPV) and accuracy to detect untreatable from treatable pulp condition were calculated for each test. Results: A significant difference was detected in the normal and a sharp lingered response to heat and cold tests. There was significant difference in the negative response to EPT between histological groups. The kappa agreement coefficient between clinical and histological diagnosis of pulp condition was about 0.843 (P<0.001). The accuracy of cold and heat tests and EPT to detect treatable pulp or untreatable pulp states were 78, 74 and 62%, respectively. The sensibility tests diagnosed untreatable pulpitis with a higher probability (NPV=63%-67%-54%, PPV=83%-91%-95% for heat, cold and EPT, respectively). Conclusion: Sensibility test results were more likely to diagnose pulpal disease or untreatable pulp conditions. However, to increase the diagnostic accuracy patient history, clinical signs and symptoms and also radiographic findings in conjunction with sensibility tests must be used. The result of this small study demonstrated a good agreement between clinical and histological pulp diagnosis.

Evaluation of Efficiency of the Two Commonly Used Pulp Test For Assessing Pulp Vitality And Sensitivity

Pakistan BioMedical Journal, 2022

Hard tissue boundaries are limited to pulp tissue and cannot be inspected directly for health evaluation so most of its evaluations are based on sensitivity testing. It is believed that electric pulp test (EPT) has some limitations in determining the vitality of the pulp. Therefore the objective in the current study was to see how well the electric pulp test and the cold test agreed in evaluating pulp vitality and sensitivity. Study Design, Place and Duration: This Observational/Retrospective study was carried from 1st March, 2021 to 31st December, 2021 at the Department of Dental Materials, Sardar Begum Dental College, Gandhara University, Peshawar. Methods: Total one hundred and eighteen patients of both genders had pulpits because of dental caries were included in this study. A range of ages were represented from 18 to 50 years old. As part of the informed written consent process, each patient was asked to provide demographic information such as their age, gender, and the type of...
