Summary:
Purpose: to compare the effects of treating teeth endodontically in either a single visit or in multiple visits based on the random selection of cases performed in clinical practice during a period of 20 years.
N= 135 single visit and 195 multiple visits cases.
Materials/Methods:
•In comparing the single- and multiple-visit procedures,
3 aspects of treatment were examined:
•The incidence of pain (severity, duration, use of medications),
•The filling procedure (underextended, overextended).
•Healing as observed in RG after 6 months to 2 years.
•The tx technique was identical for the single and multiple visits cases: thorough mechanical enlargement, irrigation with saline, obturation with GP and Ostby’s Kloro-perka sealer using lateral condensation and chloroform diffusion technique.
Most highlighted Results:
•Pain: significant differences were observed between the 2 groups in incidence & duration of pain & medications use: in the multiple visits group, more patients had no pain (62% vs 46%) and did not use medications (88% vs 67%).
•Filling: In both single and multiple visits groups, there was no significant difference in healing between under filling and overfilling cases.
•Healing: No significant difference in the number of healing cases between single and multiple visits groups.
Clinical significance:
Endodontic treatment can be performed in a single visit (saves time, restores esthetics) with no effect on the healing potential.
