Lingual nerve damage subsequent to lower wisdom tooth removal affects a small number of patients, sometimes producing permanent sensory loss or impairment. A number of surgical techniques have been described which are associated with low incidences of this distressing post-operative complication. When a technique is adopted by an individual clinician then a personal audit may be prudent to establish how effective it is in relation to established nerve injury rates. This audit looks at a technique involving the minimal interference of lingual soft tissues during lower wisdom tooth removal in a high street practice situation for patients having mild to moderate impacted wisdom teeth removed under local anaesthetic. It was concluded that the technique employed was associated with a low incidence of lingual nerve trauma, comparable with that reported elsewhere.
A spectrophotometric method was developed for the determination of etidocaine hydrochloride (EH) in injectable pharmaceutical preparation. The proposal of this work was to develop a rapid, simple, inexpensive, precise and accurate visible spectrophotometric method. The method is based on the formation of the ion-pair complex by the EH reaction with bromocresol green in the pH 4.6 which after chloroform extraction gives a yellow color that in basic medium change to blue color and exhibits a maximum absorbance at 625 nm. The calibration graph was linear over the range 2.0-6.0 microg ml(-1) EH calculated on the final yellow solution. The R.S.D. of the slope of the four lines was 0.73%. This method can be applied to injectable pharmaceutical preparation dosage studied.
OBJECTIVE: To investigate trends in oral surgery in England and Wales 1991-2000. METHODS: Oral surgery procedure data were derived from Dental Practice Board and Department of Health Hospital Episode Statistics. RESULTS: There was a 6% increase in minor oral surgery (MOS) procedures, including ordinary extractions, extractions of special difficulty, apicectomies and third molar removals, carried out in the General Dental Services (GDS) but the number of third molars removed fell by 32% after 1997. General anaesthetics (GA) administered in the GDS fell by 77% and the number of sedations rose 54% after 1998. There was concentration of minor oral surgery in practices: in the year 2000, 88% of practitioners carried out less than five third molar removals. In the Hospital Dental Service (HDS) there was a 98% increase in day surgery, and a 53% decrease in ordinary admissions for minor oral surgery. HDS waiting times remained constant over the ten year period. CONCLUSIONS: The principal trends were substantial decreases in apicectomies, third molar removals after 1997 and GAs after 1998; increases in extractions of special difficulty and concentration of MOS in the GODS. Numbers of ordinary extractions did not change. In the HDS there was a large shift from in-patient to daycase provision which has facilitated expansion of maxillofacial surgery. This is an important example of NHS reconfiguration. Perhaps the most important implication of these changes concerns the place of MOS in vocational training.
