[Effect of tinidazole-dexamethasone-iodoform paste on controlling endodontic interappointment emergencies].
OBJECTIVE
To compare the clinical effect of tinidazole-dexamethasone-iodoform paste on intracanal dressing medication for teeth with chronic periapical periodontitis with that of formocresol.


METHODS
520 permanent teeth with chronic periapical periodontitis were selected and divided randomly into tinidazole-dexamethasone-iodoform paste group (A group) and formocresol group (B group). The periapical signs and symptoms were recorded, radiographs were taken. After root canal preparation, the tinidazole-dexamethasone-iodoform paste was used as an intracanal dressing medication for one week in A group and the formocresol paper point was used in B group. During the course of canal treatment, the clinical findings were assessed with clinical periapical index (CPI), the cases were followed up for two years.


RESULTS
There was significant difference between A and B group (P<0.01), group A was better than group B. There was no significant difference between two groups of the success rate after following up two years (P>0.05).


CONCLUSIONS
As an intra-canal sterilization medication,tinidazole-dexamethasone-iodoform can reduce the occurrence of endodontic interappointment emergencies in teeth with chronic periapical periodontitis and has a good long-term result.
