In recent years, new technologies for local anaesthetics delivery have emerged as alternative methods to the traditional syringe injection. The aim of this study was to compare the efficacy of traditional syringe buccal infiltration to the Computer-Controlled Local Delivery System (C-CLADS’s) STA-Intraligamentary (Single Tooth Intraligamentary Anaesthesia) on the molars of both arches in paediatric patients, focusing on anaesthetic effect onset and effect over time.
Subjects consisted of 50 paediatric patients aged 5–13 years, randomly divided into 2 groups of 25. Efficacy and onset of anaesthesia were evaluated at time 0 and after 10, 20, and 40 minutes with a pulp tester.
Percentages of complete anaesthetic effect at time 0, 10’, 20’ and 40’ were respectively as follows: 88% and then 96% at all following time points for STA-Intraligamentary delivery system, and 56%, 64% 76% and 72% for conventional syringe (0’, p: 0.025; 10’, p: 0.005; 20’, p:0.024; 40’, p:0.024) with a cumulative Odd Ratio (OR): 7.72 (CI 95% 1.49-39.9).
The STA-Intraligamentary injection offers a statistically relevant longer anaesthetic effect and a more constant duration over time. Clinical relevance: The STA-Intraligamentary injection has a high safety and comfort, and a faster onset with a more predictable outcome compared to the traditional anaesthetic technique.
