Anesthetic effectiveness of trans-papillary injection and conventional palatal injection technique in children of age 7-10 year – A randomized controlled trial

The buccal mucosa will be wiped and dried with sterile dry cotton followed by application of 20% benzocaine topical gel (SEPTODONT PROGEL-B) with the help of Q tip. After 10 seconds patient will be injected with 2% lignocaine hydrochloride with 1:200000 adrenaline with a help of 27G needle of 15mm length. A 2ml syringe will be used for both the techniques. Then 1.0 ml of solution will be injected into the buccal sulcus after which 0.5ml of anesthetic solution will be injected in the inter papillary region or the palatal region depending up on the technique used. Anxiety level is assessed before the procedure by assessing, pulse rate(P.R), oxygen saturation(spO2) with the help of pulse oximeter while questionnaire will be administer through interview to assess anxiety.  Immediately after the LA administration, pain will be assessed in both the techniques by Visual Analogue Scale (VAS) and WONG- BAKER PAIN SCALE(FPS). After objective and subjective evaluation, and confirming that the patient is anesthetized, extraction will be done. The pain will be evaluated in immediate post extraction time by using the VAS and FAS scale. Post extraction anxiety level of child will be assessed using, pulse rate (P.R), oxygen

saturation (spO2) with the help of pulse oximeter, and questionnaire will be administered through interview. The collected data will be entered in MS excel and the statistical analysis will be done using the software, Statistical Package for the Social Sciences. One of the common reason for developing dental fear and anxiety among children is the past painful experience by the patient during dental extraction. Trans-papillary injection is one of the alternative techniques by which the patient can be administered local anesthesia comparatively in a less painful way and increase overall experience of tooth extraction and help in decreasing dental fear and anxiety which lead to more frequent dental clinic visit and in turn increase the oral health related quality of life.
