This study's aim was to assess the pattern of changes of salivary alpha amylase, heart rate, and cooperative behavior in previously naïve children receiving dental treatment under local anesthesia. </p><p> <strong>Methods:</strong> Included were 30 children with no prior dental experience who needed 4 or more sessions of dental treatment involving local anesthesia. In each session, sAA, HR, and behavior were assessed before and during the application of local anesthesia and at the end of the treatment. </p><p> <strong>Results:</strong> The highest sAA value was always observed at the end of each session overall, the value was lower in the fourth session. HR always increased during the local anesthesia, and did not vary across sessions. No significant relationship was found between child cooperation and either sAA or HR. </p><p> <strong>Conclusion:</strong> In this sample, child cooperation may not be an accurate indicator of stress. Based on salivary alpha amylase activity changes, dental treatment involving local anesthesia in naïve children appeared to be less stressful after 3 sessions. </p><hr><p></p><p> <strong>Source: </strong>Journal of American Academy of Pediatric Dentistry </p><p><a href="http://www.ingentaconnect.com/content/aapd/pd/2012/00000034/00000007/art00020jsessionid=4o0gn22f62csr.alice" target="_blank"><font color="#0000ff"> Full Text</font></a></p> HEART RATE; SALIVARY ALPHA AMYLASE; CHILD COOPERATIVE BEHAVIOR; DENTAL TREATMENT 0 0 http://idai.ir/browse.php?a_code=A-10-32-934&slc_lang=en&sid=1 Aristidis Arhakis oaristidis@gmail.com 10031947532846004073 10031947532846004073 Yes Periodontology, and Implant Biology, School of Dentistry, Aristotle University of Thessaloniki, Thessaloniki, Greece George Menexes 10031947532846004074 10031947532846004074 No Periodontology, and Implant Biology, School of Dentistry, Aristotle University of Thessaloniki, Thessaloniki, Greece Trilby Coolidge 10031947532846004075 10031947532846004075 No School of Agriculture, Aristotle University of Thessaloniki, Thessaloniki, Greece Sotirios Kalfas 10031947532846004076 10031947532846004076 No University of Washington, Seattle, Wash., USA
