the study deals with noise problems associated with the use of air-turbine drills in dental practice. noise level measurements were made on various types of dental handpieces, when operated free running and when used to cut tooth tissue. hearing acuity tests were also undertaken in 12 randomly selected dental surgeons who have been using these drills for a number of years. the results indicate ...

The investigation was carried out by evaluating the microbiological characteristics of the water before and after treatment with Er:YAG laser and turbine. The study was carried out in 2 dental surgeries. In both cases the laser and dental units were served by two independent circuits, fed by the same potable tap water. Samples were taken from the water supplying and the water leaving the turbin...

We present a patient with extensive surgical emphysema following the dental restoration the upper left first molar (tooth 26) with a high speed turbine handpiece. The clinical findings and management of subcutaneous cervical emphysema are discussed.

Cervicofacial subcutaneous emphysema is a rare complication of dental procedures with an air turbine or syringe, and dentists and oral surgeons sometimes encounter mediastinal emphysema following the presentation of extensive subcutaneous emphysema. Most emphysema occurs incidentally during tooth extraction, restorative treatment, or endodontic treatment, with only a few cases reported of cervi...

Cervicofacial emphysema and pneumomediastinum are rarely observed complications of dental interventions. The complications are associated with the use of a high-speed air-turbine dental drill. It is a potentially life-threatening condition, but the majority of cases are self-limiting and benign. We describe a patient with remarkable subcutaneous emphysema, pneumomediastinum, and partial pneumot...

The anti-suck-back ability of five new high-speed air turbine handpiece models was evaluated in this study. First, suck-back pressure with water displacement within a glass tube was measured. Next, under three different conditions, how many on-off times it takes before fluorescent stains became visible on a piece of gauze at the exhaust vent was counted and the presence of fluorescent stains on...

Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo. It is caused by loose otoconia from the utricle which, in certain positions, displaced the cupula of the posterior semicircular canal. BPPV most often is a result of aging. It also can occur after a blow to the head. Less common causes include a prolonged positioning on the back (supine) during some surgical procedu...

Extraction of the lower third molar is one of the most common procedures performed in oral surgery. In general, impacted tooth extraction involves sectioning the tooth’s crown and roots. In order to divide the impacted tooth so that it can be extracted, high-speed air turbine drills are frequently used. However, complications related to air turbine drills may occur. In this report, we propose a...

The sound produced by a dental air turbine handpiece (dental drill) can markedly influence the sound environment in a dental clinic. Indeed, many patients report that the sound of a dental drill elicits an unpleasant feeling. Although several manufacturers have attempted to reduce the sound pressure levels produced by dental drills during idling based on ISO 14457, the sound emitted by such dri...
