An analysis of current analgesic preferences for endodontic pain management.

A descriptive, cross sectional survey was developed to determine the preferences of endodontists when prescribing analgesics. Eleven clinical scenarios describing common endodontic diagnoses or procedures with specified severity of pain were provided. A survey was sent to 310 AAE members and 63 responded, providing a 20% response rate. Respondents were given various choices for analgesic prescription including various dosages of ibuprofen or acetaminophen (APAP), or combination narcotic medications. Data were analyzed by chi2 tests. Non-narcotics were preferred over narcotics for all clinical situations. Significantly more respondents selected ibuprofen 600 mg (4x a day) regardless of the severity of preoperative or postoperative pain (p<0.001). Educators and board-certified AAE members were less likely than nonboard certified AAE members to manage their patient's perceived severe pain with narcotic analgesics.

Electric pulp tester conductance through various interface media.

A conducting media is necessary when using an electric pulp tester (EPT). The objective of this study was to observe differences in conductance through various media. We hypothesized that variations in current conductance through different media exist. The pulp chamber of a freshly extracted premolar was exposed, and the cathode of a voltmeter was inserted into the pulpal tissue. The anode was coupled to the EPT handpiece. The measurement taken during dry (no interface media) EPT tip-to-tooth contact was 0 V, which served as negative control. EPT tip directly touching the cathode measured 3.9V and served as positive control. A number of media readily available in the dental office were tested. Data was analyzed using single factor ANOVA. Listerine (3.3) conducted the most voltage (p<0.5). Of nonliquids, K-Y Brand UltraGel and Crest Baking Soda & Peroxide Whitening Tartar Control toothpaste recorded significantly (p<0.05) higher voltage readings (1.4 V).
