The future of oral and maxillofacial surgery - retired viewpoint.

A reasoned argument as to why the status quo for oral and maxillofacial surgery training is not sustainable and an alternative is suggested. It is argued that the current financial burden, future pension provision and unacceptable work/life balance must be addressed immediately to ensure uptake of training posts for preservation of the specialty.

An investigation into the comparative efficacy of soluble aspirin and solid paracetamol in postoperative pain after third molar surgery.

OBJECTIVE: To compare the efficacy of soluble aspirin 900 mg and paracetamol 1,000 mg in patients with postoperative pain after third molar surgery. DESIGN: A randomised, placebo controlled, double-blind study. SETTING: Day stay units of Oral and Maxillofacial Surgery at Cardiff Dental Hospital and Hexham General Hospital, Northumberland. SUBJECTS AND METHODS: One hundred and sixty-seven (104 female) patients who required the removal of their impacted third molars under general anaesthesia. INTERVENTION: In the early postoperative period, patients were medicated with either a single dose of soluble aspirin 900 mg, solid paracetamol 1,000 mg or placebo. MAIN OUTCOME MEASURES: Pain intensity was measured on 100 mm visual analogue scales at 0, 5, 10, 15, 20, 30, 45, 60, 90, 120 and 240 minutes after dosing. Other efficacy variables evaluated included time to rescue medication and an overall assessment of the study medication efficacy by the patient on completion of the study. RESULTS: One hundred and sixty-seven patients consented to take part in the study, but only 153 were medicated. Of the 14 patients not treated, 10 failed to develop sufficient pain to enter the study, two withdrew consent, one had an adverse reaction to the general anaesthetic and one was a protocol violator. Over the four hour investigation period, patients treated with soluble aspirin reported significantly less pain when compared with those treated with paracetamol (mean difference in AUC(0-240) = -2001, 95% CI -3893 to -109, p=0.038) and placebo (mean difference in AUC(0-240) = -3470, 95% CI -5719 to -1221, p=0.003). Similarly, at 20 and 30 minutes after dosing, patients in the soluble aspirin group were reporting significantly less pain than those in the paracetamol treatment group (mean difference in pain intensity: at 20 minutes -7.9, 95% CI -15.3 to -0.6, p=0.035; at 30 minutes -10.6, 95% CI -18.6 to -2.6, p=0.010). There were no significant differences between treatment groups with respect to the number of patients requiring rescue medication, however the time to dosing was significantly longer for those taking soluble aspirin when compared with placebo (hazard ratio 2.34, 95% CI 1.41 to 3.88, p<0.001). CONCLUSION: The findings from this study showed that soluble aspirin 900 mg provides significant and more rapid analgesia than paracetamol 1,000 mg in the early postoperative period after third molar surgery.

The efficacy of buffered ketoprofen in postoperative pain after third molar surgery.

OBJECTIVE: To evaluate in a randomised, double-blind, placebo-controlled trial, the efficacy (time to onset of meaningful pain relief) of single doses of buffered ketoprofen (12.5 mg) and ibuprofen (200 mg) in 180 patients with postoperative pain after third molar surgery. METHODS: 180 adult patients who had undergone third molar surgery under general anaesthesia participated in this study. After dosing, patients recorded their time to meaningful pain relief, pain intensity on both visual analogue scales and verbal rating scales, pain relief and the need for additional analgesia. Pain recordings were made at fixed time points over a 6-h investigation period. RESULT: Buffered ketoprofen (12.5 mg) provided quicker meaningful pain relief than placebo (P = 0.023). For secondary efficacy measures (SPIDS4, SPIDS6, TOTPAR4, TOTPAR6), the buffered ketoprofen was significantly superior to both placebo (P < 0.001) and ibuprofen (200 mg) (P < 0.05). Similarly, the amount of time before taking an escape analgesic was significantly less in the placebo group than both the ibuprofen and buffered ketoprofen groups (P < 0.03). CONCLUSIONS: Buffered ketoprofen (12.5 mg) provides effective pain control in the early postoperative period after third molar surgery. This ketoprofen preparation was also superior to ibuprofen (200 mg) with respect to both reducing pain intensity and providing an earlier onset of pain relief.

The efficacy of a novel adenosine agonist (WAG 994) in postoperative dental pain.

AIMS: To determine the comparative efficacy of a new novel adenosine agonist (WAG 994) in postoperative pain after third molar surgery. METHODS: One hundred and twenty-two patients with postoperative pain after third molar surgery were randomised in a placebo double-blind trial with an active control group. In the early postoperative period patients received either a single dose of WAG 994 1 mg, ibuprofen 400 mg or matched placebos. Pain intensity score was recorded on serial visual analogue scales over a 6 h investigation period. Similarly, pain relief was completed on a 4 point categorical scale at each evaluation point. Patients had access to escape analgesic and if these were taken, the time and dosage were recorded. A sparse sampling technique was used to investigate the relationship between analgesic effects and plasma concentrations of WAG 994. RESULTS: All three treatment groups were matched for various demographic variables. For all efficacy measures, WAG 994 was not significantly different from placebo (P >0.05), whereas ibuprofen 400 mg was significantly superior to placebo (P<0.001). No significant relationships (P<0.05) were found between WAG 994 pharmacokinetic variables and efficacy measures. Conclusion WAG 994, an adenosine agonist, did not show efficacy in the management of postoperative pain after third molar surgery. Although this pain responds well to nonsteroidal anti-inflammatory drugs, it appears to be resistant to compounds that interact with purinergic receptors.

Intermaxillary fixation is not usually necessary to reduce mandibular fractures.

We undertook a retrospective study of all isolated mandibular fractures which had required active management over a 1-year period at the Maxillofacial Unit at Newcastle General Hospital. Patients with single or multiple fractures of the mandible were included in the study, if there were other simultaneous fractures of the facial skeleton, those patients were excluded. All case notes and radiographs were reviewed by a single operator. A total of 202 cases of fractured mandible were identified of which 115 fulfilled the selection criteria of: isolated fracture, no previous facial fracture, treatment by open reduction and internal fixation using titanium osteosynthesis miniplates, and all case notes and radiographs available to study. Sixty-six patients had their fractures reduced manually to obtain anatomical reduction without the use of peroperative intermaxillary fixation (IMF). Forty-nine were treated conventionally using peroperative IMF. The two groups were broadly similar in severity and type of fracture, and the method of reduction seemed to be decided by the operator according to their preference. IMF was not used routinely postoperatively. Overall there were significantly fewer occlusal discrepancies in the early postoperative period in those patients treated by anatomical reduction (6/66 compared with 16/49, P = 0.002) but there was no difference in the final outcome of the occlusion between the two methods of reduction. Avoidance of the use of peroperative IMF is more economical in time and cost, is safer for the operator, and more comfortable for the patient. As this technique produces comparable results in the long term with fewer early complications, we conclude that IMF is not usually necessary to reduce fractures confined to the mandibular bone.

The comparative efficacy of aceclofenac and ibuprofen in postoperative pain after third molar surgery.

The aim of the present placebo-controlled, double-blind study was to evaluate the comparative efficacy of single doses of aceclofenac 150 mg and ibuprofen 400 mg in 217 patients with postoperative pain after third molar surgery. Outcome of primary efficacy was judged by overall assessment of the area under the curve (AUC) of graphs for pain intensity (AUC pain) pain relief (AUC relief), both measured from serial visual analogue scales over a 6 h investigation period. Other measures of efficacy included the rate of pain reduction in the first hour, the number of patients who took 'escape' analgesics and the time before they did, and an overall assessment of pain relief score on a five-point categorical scale. Ibuprofen 400 mg was significantly superior to placebo for pain relief (P < 0.01), degree of pain reduction in the first hour (P = 0.005), and the number of patients who required escape analgesia (P < 0.001), and the time before they did (P < 0.001). The outcome for patients treated with aceclofenac 150 mg was not significantly different from that of patients treated with placebo (P > 0.05). A single dose of ibuprofen 400 mg provided significant pain relief in the early postoperative period after third molar surgery, whereas a single dose of aceclofenac 150 mg was not effective in the management of postoperative pain after this operation.

Pharmacokinetics and efficacy of low-dose ketoprofen in postoperative dental pain.

A double-blind, randomised trial was carried out to investigate the relationship between efficacy and various pharmacokinetic variables after single doses of racemic ketoprofen 12.5 and 25mg in patients with postoperative pain after third molar surgery over a 4-hour investigation period. Serial venous blood samples were obtained at 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3 and 4 hours after administration for subsequent determination of R(-) and S(+) ketoprofen. The relationship between the R(-) and S(+) ketoprofen concentrations and pain experience was summarised for each patient by the slope of the regression line for that individual. There was no significant difference (p > 0.05) between the two doses of ketoprofen for any of the efficacy measures. Peak plasma concentrations of both R(-) and S(+) ketoprofen were observed between 60 and 90 minutes after dosage. A significant negative correlation (p < 0.002) was observed between the decrease in pain scores and plasma concentrations of both R(-) and S(+) ketoprofen after each dose. However, the amount of variability in each patient's response makes it difficult to identify a causal relationship between these parameters. Low doses of ketoprofen provide satisfactory pain relief in the early postoperative period after third molar surgery. Efficacy of this analgesic does not appear to be dose related or directly related to plasma concentrations of either R(-) or S(+) enantiomers.

Are the pharmacokinetics of ibuprofen important determinants for the drug's efficacy in postoperative pain after third molar surgery?

The aim of the present placebo-controlled, crossover study was to evaluate the efficacy and pharmacokinetics of ibuprofen after a single oral dose of soluble ibuprofen 400 mg in 18 patients with postoperative pain after bilateral third molar surgery. Throughout a 5-hour investigation period, patients reported significantly less pain (P < 0.001) after treatment with soluble ibuprofen than after placebo. Peak plasma concentrations of ibuprofen occurred approximately 30 minutes after dosage. No significant correlations (P > 0.05) were observed between efficacy measures and the various pharmacokinetic parameters (AUC0-300, Cmax and Tmax) for ibuprofen after the soluble dose. It is concluded that a single dose of soluble ibuprofen 400 mg is an effective analgesic for the control of postoperative pain in the early period after third molar surgery. Efficacy of this preparation does not appear to be directly related to the drug's pharmacokinetic variables in plasma.

The efficacy of ketoprofen and paracetamol (acetaminophen) in postoperative pain after third molar surgery.

1. A placebo-controlled, double-blind, randomized trial was carried out to evaluate the efficacy of single doses of racemic ketoprofen 12.5 and 25 mg and paracetamol 500 and 1000 mg in patients with post-operative pain after third molar surgery over a 6 h investigation period. 2. Outcome variables included overall pain scores (AUC(0,360 min), maximum pain relief, pain relief at 1 h after dosage and the number of patients taking escape analgesics. 3. Overall pain scores (AUC(0,360 min) were significantly lower for all active treatments when compared to placebo (P < 0.01). 4. Both ketoprofen treatments and patients treated with paracetamol 1000 mg reported significantly greater pain relief (P < 0.01) and a later time to taking escape analgesics (P < 0.01) than patients medicated with placebo. 5. At 1 h after dosage, pain scores were significantly less (P < 0.01) after both doses of ketoprofen when compared with placebo. 6. Single doses of ketoprofen 12.5 and 25 mg, together with paracetamol 1000 mg are effective analgesics for treating post-operative pain after third molar surgery. These treatments provide up to 4 h of pain relief after this surgical procedure.

An evaluation of buffered aspirin and aspirin tablets in postoperative pain after third molar surgery.

1. Single doses (500 and 1000 mg) of both buffered aspirin and aspirin tablets were compared with placebo in a randomised double-blind trial of parallel design in patients with postoperative pain after third molar surgery. 2. Only buffered aspirin 500 mg provided significant pain relief (P = 0.016) during the 5 h investigation period. 3. A significant correlation (P = 0.004) was observed between overall pain scores after the various aspirin treatments and aspirin esterase activity. 4. Buffered aspirin preparations afforded a slight advantage over aspirin tablets in the control of postoperative pain after third molar surgery. However, the duration of analgesia was short (approximately 2 h). 5. Aspirin esterase activity appears to be an important determinant of the drug's efficacy in postoperative dental pain.

An evaluation of different ibuprofen preparations in the control of postoperative pain after third molar surgery.

1. Two separate placebo-controlled studies of parallel design were carried out to evaluate the efficacy of single doses (400 mg) of soluble ibuprofen, ibuprofen liquid in a gelatin capsule and ibuprofen tablets (Nurofen), in patients with postoperative pain after third molar surgery. 2. All ibuprofen preparations provided significant pain relief (P less than 0.05) over a 6 h investigation period. 3. Mean pain scores after ibuprofen tablets and ibuprofen liquid in a gelatin capsule were similar. 4. Soluble ibuprofen 400 mg provided an earlier onset of pain relief (20 min) than ibuprofen tablets (30 min). 5. No unwanted effects were reported in the various ibuprofen treatment groups. 6. The ibuprofen preparations evaluated in this study are effective up to 4 h for controlling postoperative pain after third molar surgery. The soluble form is more efficacious with regard to onset of action.

Sarcoidosis of the tongue--a case report.

A case of sarcoidosis, unusual in that it was confined to the tongue, is reported in a 50 year-old female. The condition resolved after 1 year of steroid therapy and excision of fibrous tethering bands. Intra-oral sarcoidosis should be considered in the differential diagnosis of lingual swelling and induration.
