RESUMEN
Background Surgical dentistry during orthodontic care often occurs in adolescence and may involve surgical removal or exposure of teeth. The invasive nature of treatment, combined with dental anxiety, means care can often be provided under general anaesthesia (GA). Best-practice guidelines however endorse conscious sedation as an alternative, where appropriate. Although a limited number of studies have shown safe and effective use of intravenous conscious sedation (IVCS) with midazolam in this cohort, robust evidence to support routine use is lacking. Aim To assess whether IVCS with midazolam can effectively facilitate surgical dentistry in adolescent orthodontic patients in primary care.Method A retrospective service evaluation was undertaken reviewing clinical records of adolescents (aged 12-15 years) undergoing surgical exposure and/or surgical removal of teeth under IVCS with midazolam.Results A total of 174 adolescents (mean age 14.2 years) attended for treatment between 2009 and 2015. Of these adolescents, 98.9% (N = 172) allowed cannulation, with all surgical dentistry completed during a single visit. Midazolam dose ranged from 2-7 mg with 79.1% of patients having good or excellent cooperation and three minor adverse events occurring.Conclusion This service evaluation shows IVCS with midazolam can effectively facilitate surgical orthodontics in carefully selected adolescents. There is however a distinct need to further explore potential for this technique to provide a viable alternative to GA.

OBJECTIVE: Dental anxiety is a barrier to attendance. Dental non-attenders may seek emergency care and may prefer to receive anxiety management measures for treatment required. Little is known about the preferences of these dental non-attenders for different anxiety management techniques. Understanding such preferences may inform management pathways, improve experiences, alleviate anxieties and encourage a more regular attendance pattern. As such, the aim of this study was to gain a greater understanding of the dental anxiety of patients attending a dental access centre for emergency dental treatment and to ascertain preferences for different anxiety management techniques. DESIGN: Cross-sectional study involving self-completed questionnaires and clinical observation. SETTING: NHS Dental Access Centre, York, UK. SUBJECTS AND METHODS: Two hundred participants not registered with a general dental practitioner, aged 18 years or over, experiencing pain and self-referred were recruited on a consecutive sampling basis. Participants completed a questionnaire eliciting demographic and dental history details, dental anxiety and preferences for dental anxiety management options. MAIN OUTCOME MEASURES: Correlation of the modified dental anxiety scale with preference for different dental anxiety management techniques. RESULTS: No significant predictive factors were found that explained preferring local anaesthetic to sedation, or general anaesthesia for restorations or extractions. Those highly anxious were less likely to consider tell-show-do techniques (p=0.001) or watching explanatory videos (p=0.004) to be helpful for overcoming their anxieties than the low or moderate anxiety groups. CONCLUSIONS: People attending access centres may represent a group who are unwilling to explore non-pharmacological methods to overcome their anxieties. This supports the need for sedation to provide treatment. Future work may include exploring in more depth the thoughts and opinions of this group of patients to improve understanding of their complex dental attitudes. From this, more effective strategies may be developed to encourage regular dental attendance.

AIM: To evaluate final year dental students' knowledge acquisition and experiences during their intravenous sedation (IVS) clinical attachment within the sedation department at Newcastle School of Dental Sciences (NSDS). METHODS: Students attending IVS clinical attachments in the period September 2012 - April 2013 completed a novel clinical knowledge test at the beginning and end of their one week attachment; a feedback questionnaire was also completed. RESULTS: A total of 70 students attended the attachment. Clinical knowledge tests were completed by 71.4% (n = 50) of students. The average test result improved from 75.1% in the pre-attachment test to 92.1% in the post-attachment test. Feedback questionnaires were returned by 65.7% (n = 46) of students. All students attained clinical experience of administering sedation and treating sedated patients. 'Teaching and Clinical Support' was rated highest, with 97.8% (n = 45) rating it as excellent. Students commented that hands-on clinical experience and clinical teaching were the most valuable parts of the attachment. Patients failing to attend appointments were considered the least useful part of the attachment. CONCLUSION: This pilot study provides an insight into undergraduate clinical sedation, which is often under reported in the literature. The clinical experience gained at NSDS exceeds GDC recommendations for undergraduate sedation. The clinical knowledge test results suggest that clinical knowledge may be better retained after direct clinical experience.

BACKGROUND: Healthcare professionals often rely on parents to provide accurate dental anxiety assessment for their children. To date no studies have reported on inter-rater agreement between children's self-reported and their parents'/guardians' proxy-reported dental anxiety in the UK. AIMS: To assess the frequency of self-reported dental anxiety in 7-16-year-old children and the inter-rater agreement between children's self-reported and parent/guardian proxy-reported dental anxiety for their children. METHODS: Data were collected prospectively from 7-16-year-old children and their parents/guardians attending two community dental clinics in Fife, Scotland (July 2012-January 2013). Dental anxiety was assessed using faces version of Modified Child Dental Anxiety Scale. Questionnaires were separately and independently completed by children and their accompanying parent or guardian. RESULTS: One hundred and thirty-two child-parent/guardian pairs participated in this study. Children's self-reported dental anxiety was 18% (n=24, 95% CI 12-25). Inter-rater agreement between children and their parent/guardian was poor for dental filling (linear weighted kappa coefficient 0.17) and tooth extraction (0.20), whereas other questions had fair inter-rater agreement (0.21-0.34). Parents' proxy-reported assessments significantly failed to recognise dental anxiety in 46% (n=11) dentally anxious children (p=0.0004). CONCLUSION: Parent/guardian proxy-reported dental anxiety differs from children's self-reported dental anxiety suggesting children should be encouraged to self-report their dental anxiety.

AIM: To assess escorts' understanding of their responsibilities to the patient 24 hours following dental treatment under intravenous sedation. STANDARDS: One hundred per cent of escorts: have been informed of their duties, have read the information sheet, expect at least a one hour appointment, identify the hazardous activities patients should avoid following sedation, travel by private transport, are aware that medications are taken as normal, should have care in place 24 hours following sedation. METHOD: This was a prospective questionnaire-based audit. Questionnaires were handed to escorts of patients receiving treatment under intravenous sedation in Newcastle Dental Hospital sedation department. RESULTS: Of 104 responses, 91.3% of escorts were informed about their duties and 79.8% had read the information sheet prior to the appointment. Boiling a kettle and Internet use were the most selected hazardous activities that escorts deemed safe for patients to carry out postoperatively (19.2%, 23.0%.) Private transport home was mainly used (car 73.1%, taxi 24.9%.) Following sedation, 93.3% of patients had an escort for 24 hours. CONCLUSION: Escorts' basic knowledge fell short of the standard. Improvements are needed to ensure patient safety. RECOMMENDATIONS: At the pre-assessment, the patient might be given an information sheet solely for the escort and encouraged to explain this to the escort. More comprehensive information listing activities hazardous to the patient 24 hours following sedation and emphasising that taking medications as normal preoperatively could be available on the treatment day. Transport information in the appointment letter might improve access. A Trust website link, a DVD and posters in the waiting room could further inform.

AIM: To determine whether adult patients' dental anxiety levels decrease following exodontia carried out under inhalational conscious sedation with nitrous oxide and oxygen (IHS) and local anaesthetic (LA). DESIGN: Retrospective analysis of pre- and post-operative modified dental anxiety score (MDAS) questionnaires completed by patients treated in a primary care oral surgery service between 21 July 2010 and 17 December 2010. METHODOLOGY: 138 patients who had undergone exodontia were divided into three groups: moderate to severe anxiety (MDAS scores 11-25) treated under IHS and LA (n = 60), mild anxiety (MDAS scores 5-10) treated under IHS and LA (n = 43) and mixed anxiety (MDAS scores 5-15) treated under LA only (n = 35). The mean pre- and post-operative MDAS scores were analysed by means of one-tailed, paired t-tests. RESULTS: The moderate to severely anxious group treated under IHS and LA showed a statistically significant decrease of 3.68 between the mean pre- and post-operative MDAS scores (p = 0.000). The IHS mildly anxious group showed a decrease of 0.07 (p = 0.392) and the LA group showed a decrease of 0.23 (p = 0.227). Neither of these results were statistically significant. CONCLUSION: These results support the use of IHS, to reduce anxiety of exodontia, in moderate to severely anxious adults undergoing minor oral surgery (MOS) procedures under LA in primary care oral surgery.

The goal of this study was to elicit the views of patients or parents/caregivers of patients with disabilities regarding access to dental care. A questionnaire was generated both from interviews with patients/parents/caregivers already treated under sedation or general anesthesia as well as by use of the Delphi technique with other stakeholders. One hundred thirteen patients from across six community dental clinics and one dental hospital were included. Approximately, 38% of the subjects used a general dental practitioner and 35% used the community dental service for their dental care, with only 27% using the hospital dental services. Overall waiting time for an appointment at the secondary care setting was longer than for the primary care clinics. There was a high rate of parent/caregiver satisfaction with dental services and only five patients reported any difficulty with travel and access to clinics. This study highlights the need for a greater investment in education and training to improve skills in the primary dental care sector.

Little is known about the anxiety patients experience before attending for dental treatment. The aim of this study was to determine, in dentally phobic patients, the temporal relationship of pre-operative anxiety levels, and the disruption to daily life caused by this. Twenty-four phobic and 19 comparison (non-phobic) dental patients were recruited. Four validated questionnaires were used to assess anxiety and quality of life, which each patient completed for 5 days prior to, and on the day of, treatment. Those in the experimental group were found to have significantly greater levels of dental and general anxiety, and a significantly lower quality of life compared with those in the comparison group. Significant temporal relationships were found with all of the questionnaires. Dental and general anxiety scores were significantly correlated with quality-of-life measures. This study suggests that phobic dental patients are experiencing significant increased anxiety, and significant negative quality-of-life effects, in this period.

The aim of this study was to develop a screening tool to assess the suitability of people with disabilities for oral care in different settings. The objectives were to investigate retrospectively the uptake of general anesthetic (GA) services and use this information to develop a composite tool. One hundred cases referred for GA were reviewed to generate data for a Delphi Panel. Patients with disabilities were the subject of a tool, devised by the Delphi Panel, to appropriately allocate patients to the most suitable care, including the patients' medical, behavioral, and social status as well as planned dental treatment complexity. A total of 124 patients, between the ages of 4 and 75 years, in seven centers were treated under sedation or GA, according to the tool. Agreement on behavior assessment between dentists and anesthesiologists was poor. The tool has the potential to identify which people with disabilities can be effectively allocated for treatment under sedation or GA.

BACKGROUND: The transmucosal route for conscious sedation in children has been reported widely in the field of medicine, but less so in dental patients. The aim of this study was to evaluate the efficacy and safety profile of midazolam (0.2 mg/kg) administered by the buccal transmucosal route, in comparison with nitrous oxide/oxygen inhalation sedation, for orthodontic extractions in 10-16-year-old dental patients. METHODS: Each patient attended for two visits and was randomly allocated to receive buccal midazolam (0.2 mg/kg) or nitrous oxide/oxygen titrated to 30%/70% at the first visit, the alternative being used at the second visit. The patients' vital signs, sedation levels and behavioural scores were recorded throughout. Post-operatively, side-effects, recall of the visit and satisfaction levels were recorded via questionnaire. RESULTS: Thirty-six patients, with a mean age of 12.9 years, completed both arms of the trial. The maximum level of sedation was achieved with buccal midazolam in a mean time of 14.42 min, compared with 7.05 min with inhalation sedation. The vital signs with both types of sedation remained within acceptable limits and the reported side-effects were of no clinical significance. Buccal midazolam was found to be acceptable by 65.7%. Only 28.6% of cases preferred this technique, the main disadvantage being the taste of the solution. CONCLUSION: Buccal midazolam sedation (0.2 mg/kg) seems to be equally as safe and effective as nitrous oxide/oxygen for the extraction of premolar teeth in anxious children. However, further research is required to refine the midazolam vehicle to improve acceptability.

The aim of the study was to compare oral midazolam and inhaled nitrous oxide as sedative agents during the management of children aged 5-10 years presenting for extraction of primary teeth under local anaesthetic. Subjects required two visits for the extraction of four primary teeth, one in each quadrant of the mouth, and were randomly allocated to be given nitrous oxide 30% in oxygen or oral midazolam 0.3 mg.kg(-1) at the first visit, the other technique being used at the second visit. Vital signs, sedation levels and behavioural scores were recorded, and postoperative recall and satisfaction were reported by the patients. Thirty-five children, with a mean [range] age of 7.4 [5-10] years, completed the treatment. The mean dose of oral midazolam given was 8.6 [3.3-16.5] mg. The mean times taken to achieve the maximum level of sedation for midazolam and nitrous oxide sedation were 15.9 [2-30] min and 6.8 [2-10] min, respectively. Physiological parameters remained within acceptable clinical limits for both types of sedation. Oral midazolam was considered acceptable by 59% and was preferred by 36%. Oral midazolam sedation in 5 to 10-year-old children was shown to be as safe and effective as nitrous oxide in oxygen sedation for extraction of primary teeth but would not be the method of choice for all patients.

AIM: To examine whether an intra-oral injection of a nonsteroidal anti-inflammatory drug (ketorolac), in association with conventional local anaesthetic techniques, would improve the pulp extirpation rate in teeth with irreversible pulpitis. METHODOLOGY: A two group double-blind clinical trial was undertaken in the Dental Casualty Department of the University of Manchester School of Dentistry. Patients were randomly allocated to either the test or control group. The test group received an intra-oral injection of ketorolac (30 mg in 1 mL) in the buccal sulcus adjacent to the tooth being treated. After an interval of 15 min, they then received 2.2 mL of 2% lidocaine with 1 : 80 000 epinephrine by buccal infiltration in the maxilla or by inferior dental block in the mandible. The control group received an intra-oral injection of normal saline (1 mL) in the buccal sulcus adjacent to the tooth being treated, followed by the same local anaesthetic regime as the test group after the 15 min interval. Fifteen minutes after the local anaesthetic injections, pulp extirpation was attempted. All patients completed the short-form McGill pain questionnaire prior to treatment and completed identical questionnaires at 6 and 24 h after treatment. RESULTS: The study protocol set the number of patients to be treated at twenty. However, as the study progressed it became apparent that the intra-oral injection of ketorolac caused significant pain to four of the five patients who received it; therefore the study was terminated after ten patients had been treated. The results from the patients treated showed no significant difference in the pulp extirpation rate between the test and control groups. However, patients with higher pain scores at baseline were less likely to have the pulp completely extirpated, irrespective of whether they were in the test or control group. Pain scores for all patients decreased significantly from baseline to 24 h. CONCLUSION: An intra-oral injection of ketorolac did not improve the pulp extirpation rate in a small group of patients with irreversible pulpitis compared with a placebo. In addition, it was associated with such significant pain on injection that it cannot be recommended as a treatment in this situation.

OBJECTIVE: The aim of the present study was to determine the validity of subjective anxiety assessment and the outcomes of management of children receiving operative dental treatment. SETTING: The study was conducted at the Departments of Sedation and Child Dental Health, Newcastle Dental Hospital, Newcastle upon Tyne, UK. SUBJECTS AND METHODS: One hundred children and adolescents aged between 8 and 15 years participated in the study. Clinicians subjectively allocated 50 children for treatment with local analgesia alone (low anxiety), and identified 50 children who had the potential to benefit from nitrous oxide and oxygen sedation (high anxiety). Participants then completed the State-Trait Anxiety Inventory for Children (STAIC), the Venham Picture Test (VPT) and the Child Fear Survey Schedule-Dental Subscale (CFSS-DS). A global rating scale classified behaviour during dental treatment. RESULTS: State anxiety and dental fear prior to treatment were significantly higher in children allocated to receive inhalation sedation (P = 0.004 and P = 0.005, respectively). There was no significant difference in trait anxiety or post-treatment state anxiety between the two groups (P = 0.69 and P = 0.06, respectively). Only 11% displayed 'negative' behaviour during treatment: 82% of this group represented those allocated to receive sedation. CONCLUSION: Children receiving inhalation sedation were significantly more anxious prior to treatment than children receiving treatment with local analgesia alone. The findings support the subjective assessment of anxiety in children; however, objective anxiety measures may assist clinicians in identifying specific fears, which may ultimately aid patient management.

AIM: To add to the evidence base for acceptable and effective paediatric conscious sedation techniques in dental primary care. OBJECTIVES: To compare three conscious sedation techniques for primary care as an alternative to dental general anaesthesia (DGA) in children. To assess the feasibility and practicality of running the trial in general dental practice. To form the basis for sample size calculations and assess scales of measurement. DESIGN: Single centre, randomised control trial (RCT). SETTING: Queensway Anxiety Management Clinic (QAMC). A primary care based general and referral dental practice for the management of anxious patients. SUBJECTS, MATERIALS AND METHODS: Sixty five children too anxious for management with relative analgesia, requiring invasive dental procedure for which dental general anaesthesia (DGA) will be required if an alternative cannot be found. INTERVENTIONS: Group 1 (n = 20) - A combination of inhaled medical air and titrated intravenous midazolam. Group 2 (n = 22) - A combination of inhaled 40% nitrous oxide in oxygen and titrated intravenous midazolam. Group 3 (n = 23) - A combination of an inhaled mixture of 0.3% sevoflurane and 40% nitrous oxide in oxygen with titrated intravenous midazolam. MAIN OUTCOME MEASURES: Successful completion of the intended dental treatment with a child who is co-operative and responsive to verbal commands. RESULTS: Fifty per cent (ten children) successfully completed treatment in Group 1, 73% (16 children) in Group 2 and 83% (19 children) in Group 3. This difference was not significant at a 5% level (chi(2) = 5.53, df = 2, P = 0.07) Of the total of 20 failures, eight children in Group 1 and one child in Group 2 were successfully treated with the addition of sevoflurane and nitrous oxide in oxygen. Only two children required referral to a hospital setting for DGA and the remaining nine children were managed with an alternative conscious sedation technique. CONCLUSION: This pilot shows that intravenous midazolam especially in combination with the addition of inhaled nitrous oxide or sevoflurane and nitrous oxide were promising safe and effective techniques, sufficient to justify progression to a definitive RCT with appropriate methods.

Failure of dental treatment due to anxiety is a common problem in children. The aim of this study was to establish whether the use of a combination of intravenous midazolam with inhalation agents (nitrous oxide alone or in combination with sevoflurane) was any more likely to result in successful completion of treatment than midazolam alone. A further aim was to evaluate the clinical viability of these techniques as an alternative to general anaesthesia. In total, 697 children too anxious for management with relative analgesia and requiring invasive dental procedure for which a general anaesthetic would usually be required, were recruited and randomly assigned to one of three groups given the following interventions: group 1 - a combination of inhaled medical air and titrated intravenous midazolam, group 2 - a combination of inhaled 40% nitrous oxide in oxygen and titrated intravenous midazolam, and group 3 - a combination of an inhaled mixture of sevoflurane 0.3% and nitrous oxide 40% in oxygen with titrated intravenous midazolam. The primary outcome measure was successful completion of the intended dental treatment with a co-operative child responsive to verbal commands. In group 1, 54% (94/174 children) successfully completed treatment. In group 2, 80% (204/256 children) and in group 3, 93% (249/267 children) completed treatment. This difference was significant at the 1% level. Intravenous midazolam, especially in combination with inhaled nitrous oxide or sevoflurane and nitrous oxide, are effective techniques, with the combination of midazolam and sevoflurane the one most likely to result in successful treatment.

OBJECTIVES: To elicit the attitudes and opinions of consultant anaesthetists working in Scotland, with regard to conscious sedation carried out by dental practitioners. METHOD: A questionnaire was designed to gauge opinion of consultant anaesthetists in Scotland on the practice of conscious sedation by dentists. The questionnaire was sent to 353 consultant anaesthetists working in 49 hospitals within the 15 health boards in Scotland. RESULTS: Of the 366 questionnaires sent, 249 were returned of which 235 were valid. This gave a response rate of 64%. In general, those questioned felt that the provision of sedation in a hospital setting was more appropriate than in general dental practice. A majority (65%) thought that it was unrealistic for anaesthetists to provide all sedation for dental treatment, although many (58%) felt that anaesthetists should take more responsibility in this area. Again, a majority (60%) agreed that dentists should be trained to use sedation techniques for their patients but a significant number (63%) disagreed with the practice of operator/sedationist. CONCLUSION: It is of concern to the dental profession that a significant number of anaesthetists do not feel that it is appropriate for dentists to be administering even the most simple methods of sedation. At present there are no clear, recognised guidelines as to the level of formal training required for the practice of conscious sedation by dentists. It is in the interests of the dental profession and the public to ensure that those choosing to practice sedation do so safely by following recognised guidelines in the training and practice of sedation.

BACKGROUND: The use of benzodiazepines for paediatric dental sedation has received limited attention with regard to research into clinical effectiveness. A study was therefore designed to investigate the use of midazolam, for i.v. sedation in paediatric dental patients. METHOD: The aim of the study was to assess the effectiveness of i.v. midazolam in a randomized, controlled, cross-over trial. Children aged 12-16 yr (ASA I and II), requiring two appointments for equivalent but contralateral dental extractions for orthodontic purposes, were recruited. Conscious sedation with either i.v. midazolam titrated at 0.5 mg x min(-1), to a maximum of 5 mg, or nitrous oxide/oxygen titrated to 30%/70% inhalation sedation was used at the first visit, the alternative being used at the second visit. Vital signs including blood pressure, arterial oxygen saturation and ventilatory frequency, as well as sedation levels and behavioural scores, were recorded every 2 min. RESULTS: Forty patients, mean age 13.2 yr (range 12-16 yr), participated in the trial. A mean dose of midazolam 2.8 mg was administered in the test group. The median time to the maximum level of sedation was 8 min for midazolam compared with 6 min for nitrous oxide (P<0.001). Vital signs for both treatments were comparable and within acceptable clinical limits and communication with the patient was maintained at all times. The median (range) lowest arterial oxygen saturation level recorded for midazolam was 97 (91-99)% compared with 97 (92-100)% for nitrous oxide. The mean (range) recovery time for midazolam was 51.6 (39-65) min and 23.3 (20-34) min for nitrous oxide (P<0.0001). Fifty-one per cent said they preferred i.v. midazolam, 38% preferred nitrous oxide, and 11% had no preference. CONCLUSION: I.V. midazolam sedation (0.5 mg x min(-1) to a maximum of 5 mg) appears to be as effective as nitrous oxide sedation in 12-16-yr-old healthy paediatric dental patients.

A randomised, controlled, crossover trial was designed to assess the safety and effectiveness of oral midazolam sedation for orthodontic extractions. Forty-six ASA physical status I children aged 10-16 years were recruited. Each child required two treatment sessions. Sedation with either oral midazolam 0.5 mg.kg-1 or nitrous oxide in oxygen was used at the first visit, the alternative being used at the second visit. Blood pressure, heart rate, arterial oxygen saturation, and sedation and behavioural scores were recorded every 5 min. Anxiety levels and postoperative satisfaction were also recorded. Blood pressure, heart rate and arterial oxygen saturation in both groups were similar and within acceptable clinical limits. The median [range] lowest arterial oxygen saturation levels for subjects in the midazolam and nitrous oxide groups were 95 [90-100]% and 98 [93-100]%, respectively. The median [range] time to the maximum level of sedation in the midazolam group was 20 [5-65] min compared with 5 [5-10] min in the nitrous oxide group (p < 0.001). The median [range] duration of treatment was similar in both groups (midazolam group: 10 [5-30] min, nitrous oxide group: 10 [5-25] min). Seventy-four per cent of subjects were prepared to have oral midazolam sedation again, 54% preferring it. Oral midazolam appears to be a safe and acceptable form of sedation for 10-16-year-old paediatric dental patients.

Flumazenil is traditionally administered intravenously to reverse the adverse effects of over sedation with benzodiazepines. The aim of this study was to test postoperative cognitive and psychomotor recovery from midazolam conscious sedation, following reversal with orally administered flumazenil. It was hypothesised that when administered by the oral route, flumazenil may enhance recovery over a prolonged period, thus increasing safety. Eighteen patients requiring intravenous midazolam sedation for dental treatment completed a randomised, double-blind, crossover trial. Following treatment the patients' sedation was reversed using either flumazenil or saline (as placebo), administered orally, on alternate appointments. Assessment of mood and cognitive function were undertaken using ClinPhone.cdr(R), a highly sensitive and specific computerised battery of cognitive tests administered by telephone prior to sedation and every hour for seven hours post reversal. Results indicate that within 20 min of administration, oral flumazenil is capable of partially reversing some cognitive and psychomotor impairments but the attentional and stimulus discrimination effects of midazolam sedation still remain.

OBJECTIVES: To assess the safety, effectiveness and acceptability of o:ral midazolam sedation for orthodontic extraction of permanent teeth in children. DESIGN: A prospective, randomised, controlled, crossover trial. METHODS: A total of 26 children aged 10-16 (ASA I), referred for orthodontic extraction of premolar or canine teeth under sedation, were included in the study. Each child required two treatment sessions for the extraction of equivalent teeth on opposite sides of the mouth. Each subject was sedated with either ora midazolam (0.5 mg/kg) or nitrous oxide and oxygen (30%/70%) at the first visit and the alternative form at the second visit. At each visit two teeth were extracted, one upper and one lower. Heart rate, arterial oxygen saturation, respiration rate, sedation and behavioural scores were recorded every five minutes. Overall behaviour, patient acceptance and patient satisfaction were recorded at the end of treatment. RESULTS: Of the 26 children included in the study there were 12 males and 14 females. The mean age was 12.5 years. The mean heart rate and respiratory rate for both groups were similar and within acceptable clinical limits. The lowest mean arterial oxygen saturation levels for nitrous oxide and midazolam sedation were 97.7% and 95.0% respectively. Although midazolam caused greater oxygen desaturation, the range (91%-100%) was within safe limits for conscious sedation. The mean level of sedation was greater in the midazolam group compared with the nitrous oxide group and all but one case completed treatment. A total of 23 patients (88%) said they would be prepared to have ora midazolam sedation again and 17 (65%) actually preferred oral midazolam to nitrous oxide sedation. CONCLUSION: Oral midazolam (0.5mg/kg) appears to be a safe and acceptable form of sedation for 10-16 year old paediatric dental patients.
