ABSTRACT
This article reports on the incidence of success following single-visit endodontic therapy. Non-surgical endodontic therapy was performed on 210 teeth in 167 patients who were rapidly deployed during the initial stages of Operation Desert Shield. Upon their return, 97 patients were recalled for follow-up evaluation. This study evaluated 102 teeth. The recall rate was 58% with a success rate of 89%.

A case report is presented demonstrating a two-rooted mandibular incisor. Because of prosthetic considerations, endodontic therapy was not performed and the tooth was extracted. However, this case reinforces the importance of proper radiographic techniques and interpretation in detecting radicular anomalies.

In vitro intracanal temperatures produced during the war lateral condensation of gutta-percha were measured using a computerized recording system that allowed repeated obturations of a root canal model. The obturations were performed using a Touch 'n Heat unit. Temperatures were recorded to an accuracy of a hundredth degree centigrade by 16 intracanal themocouples connected to the computerized measurement system. The highest intracanal temperature recorded was 114.51 degrees C at a power setting of 6, while the mean intracanal temperature increase above the average room temperature ranged from 8.18 to 65.05 degrees C. In addition, the spreader was not uniformly heated to the same temperature throughout its entire length. The hottest point on the spreader was located 5 mm from the tip.

A new model system was developed which allows intracanal temperature measurements to be recorded during repeated obturations of a human tooth root canal. A human central incisor was embedded in clear orthodontic resin and sectioned longitudinally. Sixteen thermocouples were secured at 2-mm intervals along two surfaces of the root canal. The thermocouples were connected to a computerized temperature recording system to measure intracanal temperatures produced by high-temperature thermoplasticized injectable gutta-percha. The system was capable of recording 16 simultaneous temperatures every second with an accuracy of a hundredth degree centigrade. There was a linear increase in the recorded temperatures in the root canal. However, the actual temperatures were lower than expected.

An in vitro computerized temperature measurement system was developed to measure intracanal temperatures produced by different heated gutta-percha obturation techniques. The temperatures produced by low- and high-temperature thermoplasticized injectable gutta-percha systems were recorded and compared in this investigation. The mean intrachamber temperature of the Obtura syringe was 178.68 degrees C. The mean temperature of the Ultrafil heater was 93.06 degrees C. The mean temperature of the extruded gutta-percha was 137.81 degrees C from the Obtura syringe and 62.88 degrees C from the Ultrafil cannule. The intracanal temperature of the gutta-percha recorded for both systems showed that the gutta-percha cools rapidly after injection into the canal.
