RESUMO
BACKGROUND: Previous studies on dental anxiety have examined the psychophysiological responses evoked in dentally anxious subjects by dental-related stimuli, but not during a real-life dental examination, which was achieved in the present study. METHODS: The heart rate, skin conductance level, and heart rate variability of 25 subjects with dental anxiety and 25 healthy controls were examined. Anxiety was determined by the Modified Dental Anxiety Scale and the Dental Anxiety Scale-Revised. The psychophysiological reactions of the two groups were compared during exposure to dental-related pictures, dental-related sounds, and an actual examination in a dental surgery. RESULTS: All the dental-related stimuli provoked an increase in heart rate, i.e. visual stimuli (p<0.001; 95% CI 0.98-3.95 bpm), auditory stimuli (p<0.001; 95% CI 1.34-4.99 bpm), and a dental examination (p<0.001; 95% CI 1.26-5.39 bpm). Dental-related pictures provoked inferior skin conductance level changes compared to dental-related sounds and the dental examination (visual modality vs auditory p<0.001; 95% CI 0.039-0.152; visual modality vs examination p<0.001; 95% CI 0.083-0.275). Heart rate variability manifested in a complex pattern of responses to the dental examination. However, when exposed to all three dental-related stimuli presentation conditions, the heart rate (F = 0.352, p = 0.556), skin conductance level (F = 0.009, p = 0.926), and heart rate variability parameters of subjects with dental anxiety did not differ in comparison to the healthy controls. CONCLUSIONS: This pilot study represents an evaluation of psychophysiological reactions during a real-life dental examination compared to single modality stimuli, and shows that a real-life dental examination provokes an increase in heart rate, heart rate variability and skin conductance level. Additionally, autonomic responses did not differ between the experimental and control groups. The key issue for future studies is the effect of real-life situations on the physiological and psychological state of the subjects, which should be considered when planning new research and studied in depth.

OBJECTIVE: To investigate the effectiveness of lavender oil (Lavandula angustifolia Mill) inhalation on anxiety, mood, and vital signs (blood pressure, respiratory rate, heart rate, and saturation) of patients undergoing oral surgery. Vital signs were considered as primary outcome measures. Paired anxiety tests were used as secondary outcome measures. METHODS: Patients who had dental anxiety according to the Dental Anxiety Questionnaire (DAQ) were enrolled in the study. One hundred twenty-six patients who were undergoing wisdom tooth removal under local anaesthesia were randomly assigned to the lavender oil and control groups. Paired anxiety tests (Modified Dental Anxiety Scale and State-Trait Anxiety Inventory-State Scale were performed. Vital signs were noted pre-, intra-, and post-operatively. Visual analogue scale (VAS) results were assessed. The patients' degree of satisfaction was noted. RESULTS: Pre-operative anxiety levels were similar in both groups. Significant changes in blood pressure were observed in the lavender oil group post-operatively (pâ¯<â¯.05). Most (79.4%) of the patients in the lavender oil group enjoyed the scent, 89.68% were satisfied with their experience, and 97.62% of the patients stated that they would prefer the same protocol when needed. CONCLUSION: Inhalation of lavender oil, which is one of the most powerful anxiolytic essential oils, reduces peri-operative anxiety and can be prospectively considered in future studies for its potential sedative characteristics in patients undergoing surgical procedures under local anaesthesia.

Dental anxiety causes patients to refuse or delay treatment, which may exacerbate oral diseases. The aim of the current randomized controlled trial was to determine whether progressive muscle relaxation therapy could relieve dental anxiety. The trial included 68 periodontal patients with dental anxiety scores of ≥13 who were randomly assigned to either an intervention group or a control group (n = 34 per group). The intervention group was administered progressive muscle relaxation therapy for 20 min and oral health education for 15 min before periodontal treatment once per week for 4 wk. The control group was provided with oral health education only, for the same duration. Changes in dental anxiety, depression symptoms, blood pressure, heart rate, and salivary cortisol were evaluated 4 wk and 3 months after the intervention. The intervention group exhibited statistically significantly greater reductions in dental anxiety scores than did the control group at the 4-wk (-3.82 vs. -0.89) and 3-month (-4.22 vs. -0.28) assessments. They also exhibited significantly greater reductions in depression symptoms, systolic and diastolic blood pressure, pulse rate, and salivary cortisol levels at both time-points. Progressive muscle relaxation therapy relieves tension and anxiety in dental patients.

PURPOSE: Acupressure is a non-invasive variant of acupuncture and is known to reduce general anxiety. The purpose of this study was to test acupressure's effect on children's dental anxiety. METHODS: Eight- to 12-year-old children undergoing scaling and/or restorative procedures were randomly assigned to one of the following groups: acupressure (Group 1); sham (Group 2); or control (Group 3). Anxiety was recorded for all the children using the Modified Child Dental Anxiety scale (MCDAS). Acupressure beads with a piece of adhesive strip were employed over the selected acupoints for groups one and two. Anxiety was further recorded for all the children prior to and after completion of the treatment using MCDAS. The Frankl scale was used as the objective measure to assess the behavior of all the children. A physiologic parameter (pulse rate) was also recorded. The scores obtained from all the three groups were tabulated, compared, and analyzed statistically. RESULTS: A significant difference was found in MCDAS, pulse rate, and the Frankl behavior ratings among the three groups of children, with acupressure group displaying a lower level of anxiety. CONCLUSION: Acupressure can be a viable alternative to reduce dental anxiety in children undergoing scaling and restorative procedures.

Dental treatment promotes psychosomatic change that can influence the procedure and compromise the general well-being of the patient. In this context, it highlights the importance of evaluating the function of the autonomic nervous system in individuals undergoing endodontic treatment. Thus, this manuscript aimed to analyse cardiac autonomic modulation, through non-linear indices of heart rate variability (HRV) during endodontic treatment. Analysis of 50 subjects of either sex aged between 18 and 40 years diagnosed with irreversible pulp necrosis of lower molars undergoing endodontic treatment was undertaken. We carried out fractal and symbolic analysis of HRV, which was recorded in the first session of the endodontic treatment at four intervals: T1: 0-10 min before the onset of the treatment session; T2: 0-10 min after the application of anaesthesia; T3: throughout the period of treatment; and T4: 0-30 min after the end of the treatment session. There was reduction of α1 in T2 compared to T1 and T4 (p < 0.0001). The α2 index also reduced in T2 compared to T3 (p = 0.0035). There was an increase in the α1/α2 ratio in T4 compared to T2 and T3 (p = 0.0003). It was found that 0V% was significantly lower in T2 (p = 0.002), while 2UV% was significantly higher (p < 0.0001) when compared to other points in time. In conclusion, HRV is reduced during endodontic treatment, and after applying local anaesthetic the parasympathetic component of HRV increases. These data indicate that endodontic treatment acutely overcharges the heart, supporting the stress involved in this situation.

While previous studies successfully identified the core neural substrates of the animal subtype of specific phobia, only few and inconsistent research is available for dental phobia. These findings might partly relate to the fact that, typically, visual stimuli were employed. The current study aimed to investigate the influence of stimulus modality on neural fear processing in dental phobia. Thirteen dental phobics (DP) and thirteen healthy controls (HC) attended a block-design functional magnetic resonance imaging (fMRI) symptom provocation paradigm encompassing both visual and auditory stimuli. Drill sounds and matched neutral sinus tones served as auditory stimuli and dentist scenes and matched neutral videos as visual stimuli. Group comparisons showed increased activation in the insula, anterior cingulate cortex, orbitofrontal cortex, and thalamus in DP compared to HC during auditory but not visual stimulation. On the contrary, no differential autonomic reactions were observed in DP. Present results are largely comparable to brain areas identified in animal phobia, but also point towards a potential downregulation of autonomic outflow by neural fear circuits in this disorder. Findings enlarge our knowledge about neural correlates of dental phobia and may help to understand the neural underpinnings of the clinical and physiological characteristics of the disorder.

AIM: To determine and correlate dental anxiety in children, using psychometric and physiological measures. METHODS: On hundred children (51 boys and 49 girls) were selected and anxiety was assessed using psychometric (Modified Child Dental Anxiety Scale) and physiological measures (pulse rate and oxygen saturation levels), for local anesthetic administration. Statistical analysis was carried out with SPSS software version 11.0. Metric continuous data are presented as mean ± standard deviation. Analysis between groups was carried out by using one way anova. Categorical variables were analyzed with "Fisher's exact test". For statistical significance, the probability value of < 0.05 was considered. The correlation among psychometric and physiological measures was assessed using the Spearman rank correlation. RESULTS: A very weak negative correlation between pulse rate and MCDAS(f) values was observed. The oxygen saturation level did not show significant variations and was not a reliable indicator of anxiety. CONCLUSION: Both psychometric and physiological measures have their own merits and are important clinically. Even behavioral measures, although having observer bias, can be used as an adjuvant along with these measures. It is essential to take two or more measures into consideration rather than just one to assess dental anxiety.

The effects of sound generated by an ultrasonic dental scaler and a dental turbine on heart rate, systolic and diastolic blood pressure, and hemodynamic changes in the frontal cortex were measured and compared with those of pure tone stimulation in 17 young volunteers. Near-infrared spectroscopy and the Finapres technique were used to measure hemodynamic and cardiovascular responses, respectively. The dental sound changed the various physiological parameters. To determine if this change was related to participants' previous experiences with dental treatment, participants were divided into two groups: those who had a previous unpleasant experience with dental treatment and those who had not. Participants with previous unpleasant dental experiences showed a significant decrease in cerebral blood flow. Participants who had not had an unpleasant dental experience did not show significant changes in cerebral blood flow. Thus, although sounds associated with dental treatment may reduce cerebral blood flow, this effect may depend on the dental experiences of the patient. It is recommended that dentists treat patients gently and with empathy to promote a friendly image of dentistry.

OBJECTIVE: To compare the pain and distress response of children receiving a local anesthesia injection using a computerised device (Wand) or a traditional syringe over two consecutive treatment sessions and to study whether the response to the two injection techniques was different for high or low dentally anxious children. DESIGN: Randomised controlled trial. SETTING: Secondary dental care practice specialised in treating children. SUBJECTS AND METHODS: Children were selected and randomly allocated to the Wand or traditional injection condition. Parents completed the Dental Subscale of the Children's Fear Survey Schedule (CFSS-ds). Based on video recordings of the injections, for each 15 seconds, the occurrence of five pain related behaviours was registered and a score was given on the Venham distress scale. Children rated their pain after each injection. INTERVENTION: Over two consecutive treatment sessions one group received two local anaesthesia injections with the traditional syringe and the other group received two injections with the Wand. OUTCOME MEASURES: The mean number of pain related behaviours, the mean distress scores and the self-reported pain scores were compared. Based on the CFSS-ds subjects were split into highly and low dentally anxious children. RESULTS: One hundred and forty-seven subjects participated in the study: aged 4-11 years, 71 girls. Based on the behaviour displayed during the local anaesthesia injection and the self-reported pain after the injection, no difference could be found between an injection with the traditional syringe or the Wand over the first or second treatment session. However, on the first treatment session, highly anxious children reported more pain (p = 0.001), displayed more pain related behaviour (p = 0.002) and more distress (p <0.001) than low anxious children in reaction to the local anaesthesia injection. CONCLUSION: No clear difference in the response of referred children could be found between an injection with the Wand or the traditional syringe. Level of dental anxiety was found to be an important factor in the response of children to a local anaesthesia injection.

It was hypothesized that dental anxiety, which leads to neurophysiologic alterations in heart rate, respiratory rate and blood pressure prior, during and subsequent to dental treatment, can be influenced by medical hypnosis. We report the positive impact from non-invasive hypno-sedation during dental implant surgery on a 54-year-old female patient who experienced neurophysiologic reactions as a result of the psychosomatic process of dental anxiety (dental anxiety scale value = 13). The neurophysiologic changes during dental surgery performed with and without hypnosis were compared after the patient underwent the same surgical treatment protocol. This case report was part of a study designed to evaluate hypnosis as a non-invasive therapy for dental-anxious patients over six sessions using subjective experience and objective parameters, which included electroencephalogram, electrocardiogram, heart rate, blood pressure, oxygen saturation of the blood, respiration rate, salivary cortisol concentration and body temperature.

The purpose of this study was to clarify the effects of anxiety about dental treatment on pain during treatment. Subjects consisted of 57 consenting sixth-grade students at Tokyo Dental College (male: 32, female: 25), all of whom participated in this study during their clinical training program. They knew how third molars were extracted and all had experience of assisting in tooth extraction. Prior to the study, trait anxiety in the subjects was evaluated according to the State-Trait Anxiety Inventory (STAI, Japanese version). The students were asked to read one of two scenarios describing a scene in which a third molar was extracted while imagining themselves to be the patient. Scene 1 is set in an "environment where the patient feels safe and comfortable," and the Scene 2 is set in an "environment where the patient feels strong anxiety". The subjects were asked to imagine the anxiety and pain in that scenario and evaluate that pain according to a visual analogue scale (VAS). Two scenarios were randomly shown to the subjects in a crossover manner. No significant correlation between trait anxiety and preoperative anxiety was observed. There was no difference in level of preoperative anxiety for Scene 1 and Scene 2 between the high- and low-trait anxiety groups. This suggests that there was no relationship between sensitivity to anxiety as a characteristic of the subject and amplitude of anxiety immediately prior to treatment. Scene 2 elicited significantly higher anxiety before injection of regional anesthesia, significantly higher pain during insertion of the needle, and significantly higher pain during extraction of the tooth than Scene 1. This difference suggests that patients feel stronger pain if anxiety in the treatment environment is high and that it is, therefore, important to reduce anxiety during treatment to reduce pain.

AIMS: To assess the prevalence of dental fear and reasons for irregular dental attendance among young adult university students; to describe the gender distribution of the dentally anxious population according to the perceived origins or sources of fear; to identify the time of fear development and preference for anaesthesia or sedation before dental treatment. METHOD: A questionnaire incorporating the Dental Fear Scale (DFS) with items related to sources of dental fear stimuli, together with the preference of anaesthesia or sedation before dental treatment and other characteristics. Approximately 500 questionnaires were distributed among Saudian undergraduate students. RESULTS: 368 questionnaires were completed and presented for statistical analysis. The sight and sensation of anaesthetic needles and the sight, sound and sensation of the drill were rated the most fear-eliciting stimuli. Also, females tended to be more anxious than males. Increased heart rate was the most common reported physiological response to fear resulting from dental treatment. The overall level of fear of dental work among the studied population was found to be about 39%.'Lack of time' and 'no need for treatment' were found to be the main reasons for irregular dental visits. Fear of pain and trauma were the major perceived sources of reported fear reactions and were developed mainly during childhood. About 63% of the subjects preferred to have local anaesthesia before dental treatment to prevent or ameliorate dental fear.

BACKGROUND: Pain control in dental treatment for children is very important. The purpose of this study is to describe the characteristics of local anesthetic use by pediatric dentists and to examine factors related to its effectiveness in children. METHODS: The authors observed 361 patients in 17 pediatric dental practices in Washington state while each child received restorative or surgical dental treatment. The authors recorded data concerning local anesthetic use and effectiveness. The children's mean age was 87 months, and 181 (50.1 percent) of the patients were girls. A pediatric dentist observer rated each child's anxiety before the initial injection of local anesthetic and the effectiveness of pain control during restorative treatment. The observing dentist asked the treating dentist about the effectiveness of pain control after completion of treatment. RESULTS: Forty-two of 361 children (11.6 percent) were observed to experience ineffective pain control. Fourteen of 17 dentists (82.4 percent) were observed to have at least one patient in whom pain control was ineffective. Lidocaine (2 percent with 1:100,000 epinephrine) was used by 15 of 17 dentists (88.2 percent) and in 312 of 361 cases (86.4 percent). The average amount of agent was one cartridge (36 milligrams of lidocaine). Children who were anxious, who had symptoms before treatment, and who underwent more invasive operative and endodontic procedures were more likely to experience ineffective pain control. CONCLUSIONS: The data suggest that painful treatment is relatively frequent even in specialized pediatric practice. Variability in general practice is likely to be greater. CLINICAL IMPLICATIONS: The incidence of ineffective pain control may be less if clinicians use methods to reduce anxiety and perioperative infection and symptoms.

One hundred and seventy-nine patients completed a questionnaire focusing on adverse reactions to dental local anesthetics as manifested by 16 signs and symptoms. Twenty-six percent of the participants reported having at least 1 adverse reaction. It was found that most of the adverse reactions occurred within the first 2 hours following the injection of local anesthetics. Pallor, palpitations, diaphoresis, and dizziness were the most common adverse reactions reported in the study. The results pointed to a significant relationship between anxiety, gender, injection technique, and procedure with a higher incidence of adverse reactions.

Local anaesthetic failure is an unavoidable aspect of dental practice. A number of factors contribute to this, which may be related to either the patient or the operator. Patient-dependent factors may be anatomical, pathological or psychological. This paper considers the reasons for unsuccessful dental local anaesthetic injections and describes techniques which may be useful in overcoming failure.

The effectiveness of electronic dental anesthesia (EDA) for pain control during restorative procedures was compared with local anesthetic injection (LA) in 32 children aged 6 to 12 years. Each child selected had two antimere primary or permanent molars requiring similar-sized Class I or Class II restorations. The pain levels during restorative treatment were assessed using a visual analogue scale. Heart rates and behavior were also recorded. A crossover design was used with each child acting as his/her own control. The results showed that overall, EDA was less effective than LA for cavity preparation. The reported pain scores for EDA were higher in permanent teeth for the deeper cavities, and with one of the operators. The pre- or post-treatment anxiety scores were not found to differ significantly between the two restorative appointments. However, children with the highest pretreatment scores were more likely to report higher pain scores with EDA. Despite this, 63% of the children preferred EDA to LA. Dental anxiety, cavity depth, the tooth being treated, and operator attitude may also be important factors in determining the success of EDA.

PURPOSE: The safety and efficacy of a new sedation technique for children having dental procedures under local anesthesia were evaluated. MATERIALS AND METHODS: One hundred children between the ages of 2 and 7 years who required sedation for dental procedures were administered either a combination of midazolam (0.35 mg/kg) and ketamine (5 mg/kg) or midazolam alone (1 mg/kg) rectally 30 minutes before removal to the dental chair. Pulse rate, respiratory rate, arterial pressure, oxygen saturation, adverse reactions, postoperative recovery, and behavior were recorded. RESULTS: Satisfactory sedation and anxiolysis were achieved with both drugs used in the study. When evaluating postoperative recovery, statistically significantly more children receiving midazolam alone were fully awake on admission to the recovery room and 30 minutes later. Results of physiologic monitoring, behavioral ratings, and adverse effects are reported. Excessive salivation occurred in 26% of children receiving the combination of drugs, compared with 14% receiving midazolam alone. Seven (14%) of the children receiving the combination of drugs hallucinated, compared with 21 (42%) receiving midazolam alone. Both drug groups had reliably good anxiolysis and sedation without loss of respiratory drive or protective airway reflexes. CONCLUSION: The use of a combination of midazolam and ketamine or midazolam alone is a safe, effective, and practical approach to managing children for minor dental procedures under local anesthesia. With this technique, advanced airway management proficiency is recommended.

The authors compare the effects of central electroanalgesia and premedication in hypertensive stomatological patients, administered to prepare the patients to treatment. In contrast to premedication, central electroanalgesia normalized (stabilized) the arterial pressure and pulse rate and did not reduce the rate of reaction to a light stimulus.
