Reliable local anesthesia in emergency treatment.

Patients today expect and demand painless dentistry. Problems arise when a patient presents with a dental emergency, and the dentist is not able to meet the expectations and demands for painless dentistry because the "conventional" anesthetic blocks and infiltrations simply are not effective. This paper will examine some of the reasons for ineffective anesthesia and will explain several supplemental anesthetic injection techniques to better serve his/her patients' needs.

The influence of file size, cleaning, and time on effectiveness of bead sterilizers.

A controlled study was conducted to determine the influence on disinfection of cleaning endodontic files with either dry gauze or alcohol-saturated gauze prior to placement of the files into a hot bead sterilizer. File size and length of time in the hot bead sterilizer were also investigated. Findings indicated that an alcohol wipe was more effective than a dry wipe except in the largest file tested. Using an alcohol wipe and 3 seconds in a hot bead sterilizer for No. 10 files or 5 seconds for either a No. 30 or a No. 45 file was equivalent in disinfecting ability to 8 seconds and a dry wipe using the same file sizes.

Influence of bony resorption on endodontic treatment.

A review of prognosis studies has examined success rates between samples of teeth, both with and without radiolucent lesions, treated conventionally. The presence of a lesion predisposes the endodontic case to a lower success rate. On the basis of experimental data on the use of calcium hydroxide, investigation of increasing success with placement of calcium hydroxide in the canals of teeth with periapical lesions for 3 to 10 months prior to conventional filling is proposed.

Pain: a poor parameter of evaluation in dentistry.

In summary, we must be aware of the limitations of our instruments for determining success. A diagnosis is achieved by developing a composite picture through a keen gathering of all factors leading to the disease. Pain must surely be considered in patient management and patient-dentist rapport, but to allow our judgment to be swayed by pain alone is no more rational than to hinge our diagnosis upon a single other test. It is of paramount importance that we realize that, pulpally, periodontally, and periapically, there is no correlation between amount of destruction and reported presence or absence of pain. Pain is a poor parameter of evaluation.

The effect of orthodontic force application on the pulpal tissue respiration rate in the human premolar.

This study investigates the effect of an orthodontic force on pulpal respiration in the human premolar. The participants in this study required the removal of four first premolars for orthodontic treatment. After written consent was obtained, these teeth were used in the following manner. Randomly, the premolars on one side of the mouth were designated as experimental and the premolars on the opposing side served as controls. The four teeth were removed following a 3-day application of an orthodontic force. The pulp tissue was then extirpated and used for the investigation. A radioactively labeled carbon dioxide production system was used to evaluate the effect on pulpal respiration of the orthodontic force. It is thought that this method has been proved to provide a viable and sensitive biochemical analysis of tissue respiration on very small samples over short observation periods. The data were collected and prepared for statistical analysis. This investigation demonstrated that the pulp tissue respiration in seventeen subjects was depressed an average of 27% as a result of orthodontic force application. A positive correlation between the age of the participant and the amount of tissue respiratory depression was also demonstrated. It was therefore concluded that orthodontic forces of very short duration do cause biochemical and biologic pulpal tissue alterations and that orthodontic forces may be less biologically safe as the age of the patient increases.
