Techniques to administer oral, inhalational, and IV sedation in dentistry

Dental treatments under sedation-analgesia in patients who are unable to collaborate: a prospective observational study

Background

Excessive fear of dental procedures leads to disruptive behavior during dental examinations and treatments. Dental examinations and treatments of these patients usually require additional techniques, such as sedation. The most commonly used techniques are inhalation of nitrous oxide, infusion of propofol with fentanyl, and premedication and infusion of midazolam.

Methods

A prospective observational epidemiological study was conducted on patients who required sedoanalgesia techniques for dental exploration and procedures. The reasons for the inability of patients to cooperate (excessive fear or intellectual disability), age, sex, weight, systemic pathology, oral pathology, treatment performed, time of intervention, anesthetic technique performed, and occurrence of complications were recorded.

Results

In total, 218 patients were studied. Sixty-five patients came for fear of dental treatment and 153 for presenting with a diagnosis of intellectual disability and not collaborating in the treatment with local anesthesia. The average age of all patients was 30.54 ± 17.30 years. The most frequent oral pathologies found in patients with excessive fear were tartar (6.8%) and wisdom teeth (6.4%), followed by missing teeth (5%). In patients with disabilities, a combination of tartar and cavities appeared most frequently (41.3%), followed by cavities (15.6%). The most frequently used sedoanalgesia technique was the infusion of propofol with fentanyl in both groups of patients, followed by nitrous oxide.

Conclusion

The combination of propofol and fentanyl was the most frequently used alternative in patients who were unable to collaborate because of intellectual disability or carry out longer or more complex treatments. Inhaled nitrous oxide and midazolam were the sedative techniques of choice for simpler oral treatments, such as tartrectomies, shallow obturations, and shorter interventions, or in younger patients.

A Comparative Study of Parent and Child Perspectives on Using the Intranasal Mucosal Atomization Device for Behavior Management in Pediatric Dental Sedation

Background Dental anxiety in children often necessitates sedation for effective treatment. Different methods of sedation have proved to be beneficial. However, intranasal sedation provides a needleless, rapid drug delivery method that bypasses hepatic metabolism. Intranasal sedative drugs can be delivered using a mucosal atomization device (MAD). This study aimed to find the opinions, beliefs, and existing knowledge of parents and children regarding intranasal sedation and the method of drug delivery through MAD. Materials and methods The study comprised 50 parents, aged 20 to 50, who came in with a single child, aged five to nine years. In separate rooms, parents and kids were each shown a video about the use of the intranasal sedation technique with MAD as a pharmaceutical help during routine dental procedures. After the video presentation, each participant was required to complete a pretested self-made questionnaire with 21 questions and multiple-choice options. The chi-square test was used in the statistical analysis of the completed questionnaires (P < 0.05). Paired t-test was used for behavior assessment of the children before and after intranasal sedation. Results A significant correlation between parental socioeconomic status and acceptance of intranasal sedation was observed. Parents with higher education levels exhibited a greater level of acceptance (P = 0.000). Parents whose children had prior dental experiences were more likely to view intranasal sedation as a safe option (P = 0.038). Additionally, a significant proportion of previously sedated children expressed willingness to undergo treatment using intranasal sedation. Evaluation of children's behavior before and after treatment revealed a notable improvement, indicating the effectiveness of intranasal sedation (P = 0.000). Conclusion The study thoroughly investigated how parents and children view intranasal sedation via MAD. It revealed a positive perception of safety and trust among parents regarding this method for pediatric dental procedures.

Modern sedative agents and techniques used in dentistry for patients with special needs: A review

According to the World Health Organisation, approximately 1.3 billion people worldwide experience substantial disability due to physical, mental or sensory impairment. People with special needs require special consideration and more time or altered delivery methods when receiving dental treatments. Various factors, such as patients' lack of cooperation, cognitive impairment and complex medical status, may lead dental practitioners to recommend conscious sedation. Several pharmacological agents and administrative routes are available, which achieve varying levels of sedation ranging from minimal to deep. Pre-operative assessment and careful case selection are necessary to determine the appropriate sedative agent, route of administration and level of sedation for each patient. Thus, a thorough understanding of the pharmacokinetics, risks and benefits, and implications of various sedatives available for PSN is essential to achieve the desired clinical outcomes. This review critically presents the considerations associated with the use of various sedative agents for PSN in dentistry. Considerations include patients' pre-anaesthesia medical comorbidities, cardiorespiratory adverse effects and cooperativeness, and the viable alternative treatment modalities.

The Effect of Anxiety and Stress on Acceptance of Dental Procedure before and after Inhalation Sedation in Pediatric Patients: An In Vivo Study

Aim

The study aimed to assess the anxiety and stress levels on acceptance of dental treatment in child patients approaching dental extraction procedures before and after nitrous oxide (N₂O) inhalation sedation (IHS) by measuring serum amyloid A (SAA) and salivary cortisol (SC).

Materials and methods

A total of 32 children, ages ranging from 6 to 10 years, were randomly grouped as TI (before N₂O IHS) and TII (after N₂O IHS). Saliva samples were taken for biochemical evaluation of SAA before and after the procedure. Subjectively anxiety and stress levels were evaluated using modified child dental anxiety scale (MCDAS). Wilcoxon rank-sum test was used to compare the means of dental anxiety, SAA, and SC before and after N₂O IHS. The Karl Pearson correlation coefficient was employed to determine the correlation between dental anxiety and SAA and SC before and after N₂O IHS.

Results

There were significant differences in the dental anxiety level in child patients after administration of N₂O IHS, and it also showed an increased rate of acceptance of dental treatment.

Conclusion

This study showed that N₂O is a safe and effective method in reducing dental anxiety and increasing acceptance of dental treatment in child patients with improved behavior and with no adverse effects.

Clinical significance

Anxiety and stress will always hinder the acceptance of dental treatment in child patients, especially during extraction procedures. N₂O IHS is a safe and effective technique to overcome anxiety and stress in child patients and as well as allows them to undergo dental treatment with improved behavior.

Safety and efficacy of target controlled infusion administration of propofol and remifentanil for moderate sedation in non-hospital dental practice

Background

Fearful and anxious patients who find dental treatment intolerable without sedative and analgesic support may benefit from moderate sedation. Target controlled infusion (TCI) pumps are superior to bolus injection in maintaining low plasma and effect-site concentration variability, resulting in stable, steady-state drug concentrations. We evaluated the safety and efficacy of moderate sedation with remifentanil and propofol using TCI pumps in non-hospital dental settings.

Methods

A prospective chart review was conducted on 101 patients sedated with propofol and remifentanil using TCI pumps. The charts were completed at two oral surgeons and one general dentist's office over 6 months. Hypoxia, hypotension, bradycardia, and over-sedation were considered adverse events and were collected using Tracking and Reporting Outcomes of Procedural Sedation (TROOPS). Furthermore, patient recovery time, sedation length, drug dose, and patient satisfaction questionnaires were used to measure sedation effectiveness.

Results

Of the 101 reviewed sedation charts, 54 were of men, and 47 were of women. The mean age of the patients was 40.5 ±18.7 years, and their mean BMI was 25.6 ± 4.4. The patients did not experience hypoxia, bradycardia, and hypotension during the 4694 min of sedation. The average minimum Mean Arterial Pressure (MAP) and heartbeats were 75.1 mmHg and 60.4 bpm, respectively. 98% of patients agreed that the sedation technique met their needs in reducing their anxiety, and 99% agreed that they were satisfied with the sedation 24 hours later. The average sedation time was 46.9 ± 55.6 min, and the average recovery time was 12.4 ± 4.4 min. Remifentanil and propofol had mean initial effect-site concentration doses of 0.96 µ/ml and 1.0 ng/ml respectively. The overall total amount of drug administered was significantly higher in longer sedation procedures compared to shorter ones, while the infusion rate decreased as the procedural stimulus decreased.

Conclusion

According to the results of this study, no patients experienced adverse events during sedation, and all patients were kept at a moderate sedation level for a wide range of sedation times and differing procedures. The results showed that TCI pumps are safe and effective for administering propofol and remifentanil for moderate sedation in dentistry.

Conscious Sedation in Dentistry

Sedation in dentistry has been a controversial topic due to questions being raised over its safety, especially in dental chair. Dental fear and anxiety are not only common in children but also significantly prevalent among adults due to high intensity of pain. Sharing of airway between the anesthesiologist and the dentist remains the greatest challenge. The purpose of this review is to study the recent trends in conscious sedation in the field of dentistry from an anesthesiologist's perspective. It will provide a practical outline of the pharmacokinetics, pharmacodynamics, and routes of administration of the drugs or gases used.

Assessment of Alteration in Capnometry Monitoring during Intravenous Sedation with Midazolam for Oral Surgical Procedures

INTRODUCTION

Capnography is routinely used for monitoring of patients subjected to sedation for different surgical procedures. There is still paucity of data highlighting the capnographic assessment of patients on midazolam sedation undergoing oral surgical procedures. Hence, we planned the present study to assess the alterations occurring in the end-tidal carbon dioxide (ETCO₂) values monitored during intravenous (IV) sedation with midazolam during various oral surgical procedures.

MATERIALS AND METHODS

The present study included assessment of alteration in ETCO₂ values occurring during oral surgical procedure. After meeting the inclusion and exclusion criteria, a total of 40 participants were included in the present study. Pulse oximeter with capnograph (EmcoMeditek Pvt., Ltd., India) device was used for assessment of respiratory rate (RR) and ETCO₂ values. The mean of 12 readings over a period of 1 minute before the starting of first infusion was referred to as baseline time. By evaluating the first four readings at an interval of 15 seconds during the 1st minute of infusion, we obtained the 1 minute average reading. All the data were compiled and recorded and assessed by the Statistical Package for the Social Sciences (SPSS) software.

RESULTS

A total of 40 participants were included, out of which, 20 were males and 20 were females. At the baseline time, mean value of ETCO₂ was 31 mm Hg, while mean value of oxygen saturation (SpO₂) was 36%. Out of total 40 participants, 15 showed the presence of respiratory depression. Out of these 15 participants, ETCO₂ changes from baseline were observed in 13 participants.

CONCLUSION

No oxygen should be delivered, unless until required, to the healthy participants undergoing dental sedation procedures, for marinating the sensitivity of pulse oximetry during assessment of respiratory depression.

CLINICAL SIGNIFICANCE

In patients undergoing sedation procedures, various monitoring techniques should be employed as respiratory depression is a commonly encountered risk factor.

Dental implant treatment for renal failure patients on dialysis: a clinical guideline

Chronic kidney disease (CKD) is a worldwide public health problem that is growing in prevalence and is associated with severe complications. During the progression of the disease, a majority of CKD patients suffer oral complications. Dental implants are currently the most reliable and successful treatment for missing teeth. However, due to complications of CKD such as infections, bone lesions, bleeding risks, and altered drug metabolism, dental implant treatment for renal failure patients on dialysis is more challenging. In this review, we have summarized the characteristics of CKD and previous publications regarding dental treatments for renal failure patients. In addition, we discuss our recent research results and clinical experience in order to provide dental implant practitioners with a clinical guideline for dental implant treatment for renal failure patients undergoing hemodialysis.

Evidence of pharmacological and non-pharmacological interventions for the management of dental fear in paediatric dentistry: a systematic review protocol

INTRODUCTION

Several techniques have been proposed to manage dental fear/dental anxiety (DFA) in children and adolescents undergoing dental procedures. To our knowledge, no widely available compendium of therapies to manage DFA exists. We propose a study protocol to assess the evidence regarding pharmacological and non-pharmacological interventions to relieve dental anxiety in children and adolescents.

METHODS AND ANALYSIS

In our systematic review, we will include randomised trials, controlled clinical rials and systematic reviews (SRs) of trials that investigated the effects of pharmacological and non-pharmacological interventions to decrease dental anxiety in children and adolescents. We will search the Cochrane Database of Systematic Reviews, the Cochrane Database of Abstracts of Reviews of Effects=, the Cochrane Central Register of Controlled Trials, PubMed, PsycINFO, Cumulative Index to Nursing and Allied Health Literature and the Web of Science for relevant studies. Pairs of review authors will independently review titles, abstracts and full texts identified by the specific literature search and extract data using a standardised data extraction form. For each study, information will be extracted on the study report (eg, author, year of publication), the study design (eg, the methodology and, for SRs, the types and number of studies included), the population characteristics, the intervention(s), the outcome measures and the results. The quality of SRs will be assessed using the A Measurement Tool to Assess Reviews instrument, while the quality of the retrieved trials will be evaluated using the Cochrane Handbook for Systematic Reviews of Interventions criteria.

ETHICS AND DISSEMINATION

Approval from an ethics committee is not required, as no participants will be included. Results will be disseminated through a peer-reviewed publications and conference presentations.

Risks and benefits of pre-operative dexmedetomidine in oral and maxillofacial surgeries: a systematic review

INTRODUCTION

Oral and maxillofacial surgeries might induce anxiety and pain to the patients. Sedative agents are one of the best ways for eliminating such consequences. Dexmedetomidine (DEX) is a recent sedative agent which presents higher sedative quality with greater specificity than other drugs. The aim of present paper is to evaluate the risks and benefits of administrating DEX during oral and maxillofacial surgeries by reviewing high quality released articles. Areas covered: Searches on PubMed, Scopus and Web of Science databases were completed with focus on randomized controlled trials (RCT). Related articles, from 2000 to 2015, were selected based on inclusion criteria and quality assessments factors. Full texts of the selected articles were screened and their significant information were gathered for judgments. Expert opinion: 17 RCTs on a total of 765 patients were screened. Some of the difficulties during reviewing the articles were: different pharmacokinetic and pharmacodynamics of drugs when combined with DEX, different time spots and method of monitoring, including studies on both minor and major surgeries for better data collection. Recent researches are going to focus on application of DEX for in-office procedures because of its desirable properties. Nevertheless, the analgesic and amnesic features of DEX are still questionable.
