Four types of topical anaesthetic agents: evaluation of clinical effectiveness.

In this study, four anesthetic agents of different forms and contents, namely: EMLA 5% Cream (lidocaine 2.5 percent, prilocaine 2.5 percent), Vision-Gel (benzocaine 20 percent), Anesthetic Tabs (tetracaine hydrochloride 0.68 mg, cincocain hydrochloride 0.02 mg), Xylocaine 10% aerosol (lidocaine 10 percent) were evaluated in terms of effectiveness in decreasing the intra-oral injection pain. Six groups each consisting of 20 children were constituted from 120 children aged between 10-15 years. The responses of the patients to the pain were evaluated using a visual analogue scale. Consequently, of all the other anesthetic agents used in the present study, Vision Gel was observed to be the most effective.

[Effect of dowel space preparation on the integrity of the apical seal]. / Post-core yapiminda apikal sizdirmazligin korunmasi.

Fifty-six single-rooted maxiller teeth obturated with amalgam, N2 and AH26 were tested in vitro to determine if dowel space preparation had an effect on apical seal. Dye penetration was evaluated using 210 UV Spectrophotometer and it was observed that the use of AH26 with or without gutta-percha to seal the root was the most suitable technique on apical seal and dowel space preparation did not influence the sealing ability of it.
