Purpose:
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).
Conclusion:
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.
