Evaluation of a new paediatric dentistry intravenous sedation service

Bibliometric analysis of pediatric dental sedation research from 1993 to 2022

Statement of problem

Bibliometric analysis methods were used to evaluate pediatric dental sedation research and to identify topical hotspots using quantitative and qualitative methodologies.

Purpose

To conduct bibliometric analysis on the retrieved data and to foresee the development of trends and hotspots in this research area.

Material and methods

We retrieved appropriate research articles from the Web of Science Core Collection on January 1, 2023. VOSviewer, Citespace and the Bibliometrics website were used to conduct bibliometric analysis on the retrieved data. GraphPad Prism 10.0 (GraphPad, San Diego, CA, USA) was used to conduct the statistical analysis.

Results

A total of 396 publications on pediatric sedation in dentistry, published between 1993 and 2022, were retrieved from online databases. The USA published most papers. Furthermore, the most frequent countries who cooperated were the USA and Canada. Six of the top ten publishing establishments were USA based. Papers on the research have appeared primarily in the journals of Dentistry and Anesthesiology. Keyword co-occurrence and co-citation cluster analysis revealed that the most common topics mainly were: dental anxiety; conscious sedation; dental caries; midazolam; propofol; hypoxemia.

Conclusions

During the three decades, the focus of pediatric sedation research has been on drugs, dental anxiety and procedural sedation. Keyword burst detection indicated that procedural sedation; adverse event; respiratory depression is an emerging research hotspot.

Safety of deep intravenous propofol sedation in the dental treatment of children in the outpatient department

Background/purpose

Intravenous sedation with propofol in the dental treatment offers an alternative to inhalation sedation or general anesthesia. The aim of this study was to evaluate the safety and identify risk factors for intraoperative complications.

Materials and methods

Uncooperative children who could not complete dental treatment under non-pharmacological behavior management or mild-to-moderate sedation in the outpatient pediatric department were selected. Details and time of dental treatment; intraoperative vital signs data, including blood pressure, heart rate, respiratory rate, pulse oxygen saturation (SpO2), end-tidal carbon dioxide, and electrocardiogram; and incidence of intraoperative and postoperative complications were recorded.

Results

Overall, 344 children were selected, with 342 completing dental treatment. The dental treatment time was 20-155 (median, 85; interquartile range, 70-100) min. The number of treated teeth was at least 1 and at most 13 (median, 6; interquartile range, 5-8). Among 342 children, 35 (10.2%) had their treatment interrupted temporarily due to choking cough. No serious complications occurred; the incidence rate of minor complications was 47/342 (13.7%). Tachycardia was observed in 5/342 (1.5%) cases, oxygen desaturation (SpO2 < 95%) in 18, and hypoxemia (SpO2 ≤ 90%) in 25. The treatment duration was significant longer in cases with than without complications (P < 0.05), and children coughing during treatment were more likely to have complications (P < 0.05). Postoperative restlessness occurred in six children, but there was no vomiting, aspiration, or respiratory obstruction.

Conclusion

Decreased oxygen saturation is the most common complications. Cough during treatment and longer treatment duration were risk factors for complications.

Quality of dental treatments under intravenous sedation among patients with disability: A self-matching study

Background/purpose

Patients with disabilities usually have difficulties in communication and mobility, and the quality of the dental treatments are often inferior. This study uses the Taiwan National Health Insurance Database to analyze the quality of dental treatment for patients with disabilities who receive intravenous sedation (IVS).

Materials and methods

This study selected patients with disabilities who received dental treatment under IVS. Their oral cavity was divided into three major sections: anterior teeth, upper posterior teeth, and lower posterior teeth. Self-matching of the same section was conducted to observe whether operative dental treatment (OD) with or without IVS affected the occurrence of dental retreatment. This study observed the occurrence of refilling and the duration from the end of treatment until retreatment to compare treatment differences with or without IVS.

Results

After self-matching, this study found 158 patients who received dental treatment within the same section with and without IVS. During a follow-up period of 17 years, 75.18% of the patients who received OD treatment required refilling, 10.87% required endodontic treatment, and 5.67% required tooth extraction. After OD treatment with IVS, the risks of refilling, endodontic treatment, and tooth extraction were 0.71 (95% CI: 0.58-0.87, P < 0.001), 0.77 (95% CI: 0.48-1.23, P = 0.28), and 0.64 (95% CI: 0.32-1.27, P = 0.20), respectively.

Conclusion

For patients with disabilities, OD treatment with IVS significantly reduces the risk of refilling compared with OD treatment without IVS. IVS can be ideal for people with disabilities who receive dental treatment.
