1. Introduction
Dental procedures in pediatric patients frequently necessitate anesthesia to effectively manage pain and anxiety, ensuring treatments are both effective and comfortable. Various anesthesia modalities, including local anesthesia, sedation and general anesthesia, are employed based on the procedure’s complexity and the patient’s individual needs. A comprehensive understanding of the distribution and efficacy of different anesthesia types is imperative for optimizing pediatric dental care. Effective pain and anxiety management not only enhances immediate treatment experiences but also fosters regular dental visits, crucial for maintaining oral health. The American Academy of Pediatric Dentistry (AAPD) strongly recommends general anesthesia (GA) for pediatric patients unable to cooperate, those for whom local anesthesia is ineffective, extremely fearful, anxious or uncommunicative patients, those requiring significant surgical procedures, those benefiting from GA to prevent psychological trauma or minimize medical risks and those needing immediate, comprehensive oral care [
1,
2].
Children with high anxiety or phobias may require targeted pharmacological support alongside behavior guidance strategies, such as behavioral techniques, nitrous oxide sedation, intravenous sedation and general anesthesia [
3]. Anesthesia is pivotal in pediatric dentistry as it enables necessary procedures to be performed without stress and pain. The choice of anesthesia—local, sedation or general—depends on factors such as the patient’s age, the procedure’s complexity and the patient’s health and anxiety levels. Effective anesthesia management is crucial in preventing dental fear and anxiety, promoting positive dental experiences and encouraging lifelong dental health habits. Under GA, multiple oral issues can be addressed in a single session, reducing stress for both patient and caregiver and lowering costs and logistical demands [
4]. Treatment under GA enables high-quality restorative care, achieving outcomes comparable to those in nondisabled individuals during chairside treatment [
5]. The use of minimal sedation (MS) allows for a step-by-step resolution of dental problems in patients with high levels of anxiety and/or fear but who demonstrate minimal cooperation.
Follow-up visits are essential for monitoring dental treatment success and early complication detection. Adherence to follow-up appointments is crucial for promptly addressing issues and preventing further dental problems. Analyzing follow-up compliance by gender and sedation/anesthesia type can provide insights into factors influencing adherence, aiding the development of targeted interventions to enhance compliance. Caregiver adherence to postoperative care plans is as crucial as the procedure itself [
6]. Despite high postoperative parental ratings, many patients continue to develop new caries or maintain inadequate oral hygiene, indicating the need for more effective follow-up care [
7].
The demand for GA services is influenced by a complex interplay of factors, including economic conditions, race, income, healthcare provider policies and the availability of facilities and trained personnel. These factors contribute to significant variations in GA rates across different regions, both within the U.S. and globally. Economic disparities, such as income levels, play a crucial role, with children from lower-income families being more likely to require GA due to higher rates of dental caries [
8]. Racial and ethnic differences also impact GA utilization, with certain minority groups experiencing disproportionately higher rates of severe dental conditions [
9]. Moreover, healthcare provider preferences and policies can further influence GA rates. For instance, in the U.S., variations in GA rates across states cannot be fully explained by reimbursement rates or the severity of dental conditions alone, suggesting that other social determinants and provider practices are also at play [
10]. These complexities lead to inconsistencies in GA rates, making direct comparisons between countries, and even within regions of the same country, challenging. Currently, there is a lack of comprehensive studies that compare GA rates internationally, likely due to these underlying disparities.
Despite these disturbances, the overall trend shows an increasing reliance on GA services, driven by both rising demand and increasing availability. However, this upward trend also raises concerns about the associated costs and potential overuse of GA, highlighting the need for early preventive care to reduce the reliance on such extensive interventions [
11,
12,
13,
14,
15,
16]. Moreover, this trend is particularly evident in pediatric practices where complex or extensive treatment needs arise. In many regions, including Germany, alternatives to GA are uncommon for such cases [
16,
17,
18,
19,
20]. Numerous studies have documented the recurrent need for dental treatments under GA, driven by factors such as the desire to avoid child distress, increased caries prevalence in certain populations and a growing preference for GA as a standard care model [
17,
18,
19,
20,
21]. Additional factors include lower parental health literacy, parental guilt and the convenience that GA offers, particularly in managing multiple dental issues in a single session. Moreover, some dentists prefer GA due to concerns about patient safety, liability and the lack of training in alternative sedation techniques [
15]. The rising demand for GA is paralleled by an increasing need for sedation treatments, highlighting a broader trend in pediatric dentistry toward more comprehensive anesthesia management strategies [
22,
23,
24,
25].
Previous studies have focused on immediate outcomes of various anesthesia types in pediatric dentistry, highlighting the crucial role of MS and GA in managing pain and anxiety and their positive impacts on treatment success and patient comfort. However, research on long-term follow-up compliance and the influence of different anesthesia types on compliance is limited. Additionally, comprehensive data on gender differences in follow-up adherence and treatment outcomes are lacking. Service availability, dentist expertise and confidence and patient/practitioner convenience influence rising GA rates [
26]. The existing literature lacks detailed analysis of the long-term impacts of different anesthesia types on follow-up compliance and treatment outcomes. Understanding these long-term effects is vital for developing evidence-based guidelines for anesthesia use in pediatric dentistry. Medically compromised children and those treated with more composites and fewer sealants or extractions are more likely to require repeat GA within four years [
20]. Gender differences in follow-up compliance and treatment outcomes remain underexplored. Identifying significant differences based on gender could aid in tailoring follow-up protocols and interventions to ensure optimal care for all patients.
To bridge these gaps, comprehensive data analysis is required to evaluate the distribution of MS and GA, their duration, follow-up compliance and treatment outcomes across different patient demographics. This study aims to provide an in-depth analysis of these factors, contributing valuable insights into pediatric dentistry. The findings will inform clinical practice, assisting dentists in selecting the most appropriate GA or MS type for their patients and developing strategies to improve follow-up compliance and overall treatment success. By addressing these detailed points in the introduction, this manuscript will lay a robust foundation for understanding the study’s significance and objectives, setting the stage for subsequent analysis and discussion.
The aim of this study was to evaluate the distribution of two types of GA and nitrous oxide inhalation sedation used in pediatric dental procedures, analyze their effectiveness and impact on treatment outcomes and assess follow-up compliance, with a focus on gender differences. This study determined the distribution of anesthesia types used in pediatric dental procedures, analyzed the duration of MS and GA in relation to dental procedure complexity and examined the gender distribution among patients receiving different anesthesia or sedation types. Additionally, it calculated the DMF index for patients and the type of dental procedures (e.g., restorative treatment, teeth extraction), assessed follow-up attendance rates by gender and anesthesia/sedation type, evaluated the need for further treatment and reasons for retreatment and analyzed long-term dental treatment outcomes with a focus on complications and success rates.
4. Discussion
The aim of this study was to evaluate the distribution of two types of general anesthesia (GA) and nitrous oxide inhalation sedation used in pediatric dental procedures, analyze their effectiveness and impact on treatment outcomes and assess follow-up compliance, with a focus on gender differences. Dental procedures in children often necessitate the use of anesthesia to manage pain and anxiety, ensuring treatments are carried out effectively and comfortably [
1,
2]. Various anesthesia modalities, including local anesthesia, sedation and GA, are employed depending on the complexity of the procedure and the specific needs of the patient. Understanding the distribution, effectiveness and long-term impacts of these anesthesia types is crucial for optimizing pediatric dental care. Proper anesthesia management not only improves the immediate treatment experience but also promotes regular dental visits, which are essential for maintaining oral health.
To achieve these objectives, this study analyzed the distribution of different GA types and dental sedation, their duration and follow-up compliance, with a focus on identifying any significant gender differences. By providing a detailed analysis of these factors, this study seeks to contribute valuable insights to the field of pediatric dentistry, helping practitioners choose the most appropriate anesthesia type for their patients and develop strategies to improve follow-up compliance and overall treatment success.
Our findings, where Type 2 anesthesia (general anesthesia) was extensively used, align with its recognized effectiveness in managing severe and complex dental conditions. The ability of general anesthesia to facilitate comprehensive treatment in a single session, thereby reducing patient and caregiver stress, as well as associated costs and logistical demands, underscores its importance in pediatric dentistry. This widespread use reflects the critical role of general anesthesia in cases where other anesthesia modalities are insufficient, supporting its strategic application in accordance with guidelines for managing more challenging pediatric dental patients [
1,
2].
According to the results, Type 2 anesthesia was the most frequently used, with a total of 1260 instances, followed by Type 1 (163 instances) and Type 3 (158 instances). This finding aligns with the growing body of evidence suggesting that rates of dental treatment under GA have been increasing over time. Previous studies have documented similar trends, indicating a rise in the use of GA for pediatric dental procedures due to various factors, including increased caries experience in children and a preference for GA as a model of care [
8,
9,
10,
11,
12,
13,
14,
15]. This could be because alternatives to GA are not very widespread for patients with extensive treatment needs in pediatric dental practice [
16].
Type 2 anesthesia had the longest average duration at approximately 2.78 h, significantly longer than Types 1 and 3. The extended duration of Type 2 anesthesia procedures reflects the complexity and severity of the dental conditions being treated. This aligns with findings from previous studies which reported that procedures requiring longer durations of anesthesia are typically more intricate and severe [
13].
The gender distribution across all types of anesthesia showed a slight predominance of male patients, with Type 2 anesthesia having 44.13% female and 55.87% male patients. The relatively balanced gender distribution across different types of anesthesia suggested that clinical needs, rather than patient demographics, predominantly drove the choice of anesthesia type. This observation is in line with previous research indicating that the decision to use a particular type of anesthesia is more influenced by the clinical presentation and the complexity of the dental procedure rather than gender biases [
12].
Type 2 anesthesia was also associated with the highest DMF index (7.43), indicating more severe dental conditions. This finding was consistent with the higher usage rate and longer duration associated with Type 2 anesthesia. Previous studies have shown that patients with higher DMF indices often require more extensive dental interventions, which are typically performed under GA [
14]. The correlation between high DMF indices and the use of Type 2 anesthesia underlined the necessity for intensive dental care in these patients. Type 2 anesthesia showed the highest mean follow-up visits at 6 and 9 months. The high follow-up rates for patients who received Type 2 anesthesia suggested a need for more rigorous postprocedure monitoring. This aligned with findings from previous studies, which emphasized the importance of follow-up care in patients undergoing extensive dental procedures under GA to monitor recovery and manage any potential complications [
13].
According to the results, female patients generally had higher follow-up attendance rates compared to male patients across all follow-up periods. This observation aligns with broader healthcare trends where female patients often exhibit higher compliance rates with follow-up appointments and medical advice [
15]. Ensuring high follow-up compliance is crucial for maintaining dental health, especially in pediatric populations and these gender differences can help tailor follow-up strategies to improve overall attendance rates.
The null hypothesis of this study was that there is no significant difference in follow-up compliance and treatment outcomes based on the type of anesthesia or the gender of the patient. Our findings partially reject this hypothesis, as significant differences were observed in follow-up compliance based on the type of anesthesia used, particularly with Type 2 anesthesia showing the highest follow-up rates. The statistical significance of these findings underscores the need to incorporate them into the discussion to accurately interpret the implications of this study. However, gender did not significantly influence the type of anesthesia used, supporting the null hypothesis in that regard. Overall, this study underscores the importance of tailored anesthesia plans and follow-up protocols to optimize pediatric dental care. Future research should focus on prospective designs, larger and more diverse patient populations and standardized protocols to enhance the robustness and applicability of the findings.
5. Conclusions
In summary, our findings highlight the predominance of GA induced using inhalational anesthetic agents with muscle relaxants for severe dental conditions, reflecting its suitability for managing complex cases. This aligns with the increasing trend of using GA in pediatric dentistry [
8,
9,
10,
11,
12,
13,
14,
15,
16]. Moreover, this type of GA had the longest average duration and patients receiving it also had the highest DMF index, indicating its association with more severe and intricate dental procedures, consistent with previous studies [
13,
14].
It should be noted that while GA is effective for managing severe dental conditions, it carries inherent risks, including a 1 in 400,000 risk of life-threatening complications. This underscores the need for careful patient selection and monitoring and the importance of adhering to evidence-based guidelines in improving patient safety [
27,
28]. Despite high postoperative parental satisfaction, new caries or inadequate oral hygiene post-treatment are common, suggesting the need for more effective and frequent follow-up care [
7]. The follow-up compliance for GA was highest for Type 2 anesthesia at 6 and 9 months, mirroring findings in the literature [
13].
The gender distribution showed a slight predominance of male patients across all anesthesia types, consistent with broader healthcare contexts where clinical needs primarily drive anesthesia choice [
12]. Interestingly, while gender distribution did not significantly influence the choice of anesthesia, the higher follow-up compliance among female patients suggests potential gender-specific behavioral trends in healthcare engagement. These findings highlight the importance of not only selecting the appropriate anesthesia based on clinical needs but also developing tailored follow-up protocols that consider patient demographics and the severity of the dental condition. Overall, this study underscores the importance of tailored anesthesia plans and follow-up protocols to optimize pediatric dental care. Future research should focus on prospective designs, larger and more diverse patient populations and standardized protocols to enhance the robustness and applicability of the findings.
6. Limitations of the Study
Despite providing valuable insights into the effectiveness of different anesthesia types in pediatric dental procedures, this study has several limitations that must be acknowledged. The study’s retrospective design relies on existing clinical records, which may contain incomplete or inaccurate data entries. This could affect the reliability of the findings, as not all relevant information may have been captured uniformly across all patient records. While the study included a substantial number of patient records, the sample sizes for certain subgroups, particularly specific age groups or patients with unique medical conditions, were relatively small. This limits the statistical power to detect differences within these subgroups and may affect the generalizability of the results. The dataset comprised records from multiple years and potentially different clinical settings. Variations in clinical practices, anesthesia protocols and follow-up procedures over time and across different practitioners could introduce heterogeneity that may influence the study outcomes. The follow-up periods ranged from 6 months to 60 months. However, not all patients had consistent follow-up data across all these time points. Variations in follow-up duration could impact the assessment of long-term outcomes and compliance rates. As a retrospective study, there was no randomization of patients to different types of anesthesia. Consequently, the observed associations between anesthesia type and outcomes could be influenced by confounding factors, such as the severity of dental conditions, patient comorbidities and practitioner preferences. The study relied on follow-up data, which could be affected by patient and caregiver compliance with scheduled appointments. Variations in compliance may introduce bias, particularly if noncompliance is systematically related to certain patient characteristics or anesthesia types. While the study identified correlations with specific medical histories, detailed information on all relevant medical conditions was not uniformly available. This limits the ability to fully explore the impact of various medical histories on the outcomes. The findings of this study are based on data from a specific geographic region and healthcare system. Therefore, the results may not be directly applicable to other regions or healthcare settings with different patient populations, healthcare policies and clinical practices. Acknowledging these limitations is crucial for interpreting the study’s findings and for guiding future research efforts aimed at improving pediatric dental care. Future studies should consider prospective designs, larger and more diverse patient populations and standardized protocols to address these limitations and enhance the robustness of the findings.
