Local anaesthesia is often uncomfortable for both patient and clinician. However, it does not have to be this way, as Dr Aneta Olszewska will show in a two-part webinar series that will focus on the benefits of computer-controlled local anaesthesia systems. Prior to her online seminar, Olszewska spoke to Dental Tribune International and shared some insights into the topic she will be covering.

Dr Olszewska, what made you decide to lecture about computer-controlled local anaesthesia?
According to the literature, seven out of ten dentists are stressed when they administer local anaesthesia. This rate is something we should work on. One of the topics of my lectures at university is that of fear and pain in dentistry. Questions raised at the lectures, together with my own observation of my students, have also convinced me that additional training in anatomy, physiology and anaesthesia administration techniques is key to success in modern dentistry.

Computer-controlled anaesthesia presents several advantages, such as an atraumatic experience for the patient and a lower drug dose. But what are the technique’s limitations, and is there a patient group unsuitable for this?
In most of the cases in the dental office, we can successfully use computer-controlled local anaesthetic delivery (CCLAD); however, the time taken for administration seems to be sometimes a limitation. In some patients, such as those with temporomandibular joint disorders, prolonged injection can provoke painful sensations, but there are some ways to prevent these that I would like to share during the webinar.

In addition, with very active children, it is difficult to expect cooperation during long administration, especially with local anaesthetic nerve block; however, the need for this type of anaesthesia is not frequent in young children and can be replaced by other types of CCLAD, such as periodontal ligament anaesthesia.

What are the main learning objectives for those who will be watching your webinars?
After these webinars, dental professionals should be able to ensure that their patients experience comfortable and successful treatment. This improved outcome will encourage compliance with follow-up visits. Furthermore, they should be able to maintain slow, safe deposition rates in different types of injections of CCLAD. Lastly, clinicians might benefit ergonomically, for example by reducing the muscle activity and force required to give injections.

Editorial note: The first 1-hour webinar by Olszewska, titled “Computer-controlled local anaesthesia: Why you should swap your traditional syringe or carpule for a digital system”, will be presented live on Thursday, 10 September, at 5 p.m.BST. The second 1-hour webinar, titled “Computer-controlled local anaesthesia and paediatric patients: How to make your injections safe and effective”, will be presented live on Thursday, 24 September, at 5 p.m. BST. Participants will have the opportunity to ask questions about the topics, as well as earn a continuing education credit for each webinar by answering a questionnaire after each lecture. Registration on the Directa Dental Group website is free of charge.
