ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the retractive effects of different gingival retraction agents.</p><p><b>METHODS</b>Thirty subjects with healthy gingival conditions were recruited to the trial, and the buccal gingival sulcus of the hibateral first max-illary premolars of each subject (n=60) were treated randomly with one of the six agents--Group A was tetrahydrozoline hydrochloride, Group B was oxymetazoline hydrochloride, Group C was epinephrine hydrochlorid, Group D was AlCl3, Group E was Fe2 (SO4)3, and Group F was normal saline as control. Both pre-treated and post-treated accurate impressions of buccal gingival sulcus of the experimental teeth were made, so were the anhydrite casts. The casts of experimental teeth were sectioned into 2 mm slices bucco-lingually at the buccal eminence. Then the width of the sulcus was measured as the distance from the tooth to the crest of the gingival under a low-power microscope to compare the effect of these gingival retraction agents.</p><p><b>RESULTS</b>The width of gingival sulcus became larger after the treatment in all groups (P < 0.05). Either Group A or Group B had greater gingival retraction effects than Group C and Group F (P < 0.05). Except Group F, both Group D and Group E had no significant differences from the other groups (P > 0.05). There was no statistically signification between Group D and Group E (P > 0.05), neither was there any statistically significance between Group A and Group B (P > 0.05).</p><p><b>CONCLUSION</b>Tetrahydrozoline manifested excellent effect of gingival retraction.</p>
