The use of fiberoptic handpieces in dentistry may have advanced faster than has the knowledge on how to use them. Differences in brightness are extreme in the dentist's work environment and may result in the dentist's experiencing fatigue. This article discusses lighting of the operating field in general, presents basic characteristics of available handpiece fiberoptic systems, and provides the dental practitioner with guidelines for adjustment and safe use of intraoral fiberoptic lighting.
The results of this study suggest that lumbar support is a significant factor in reducing muscle activity of the upper and lower back for the dentist practicing sit-down dentistry. The importance of lumbar support should be emphasized in any criteria listing correct work posture for the dentist. Under the conditions of this study, stool heights did not influence muscle activity significantly, but did suggest a trend in considering problems of the lower back posture--low stool heights (90 degrees and 75 degrees) produced lower activity than a high stool height (105 degrees) if the back was supported. Therefore, in regard to muscle activity, results of this study suggest that the dental operator should sit low with the lumbar support always in contact with the lower back.
