Brief summary
This project will be built upon a recently published systematic review that the project investigators have conducted. This study is being completed as part of Dr Sachin Kulkarni’s Doctor of Philosophy (PhD) program at Griffith University. Purpose of the study: To determine the efficacy of Photobiomodulation on providing anaesthesia of teeth. Fear of dental aesthetic injection can produce anxiety and contribute to dental phobia. Recently, other methods have been studied for their effectiveness to produce anaesthesia. One such method is known as Photobiomodulation. The purpose of this study is to utilise laser to assess where the sensitivity of the nerve inside the tooth reduces. Public: The purpose of this study, or hypothesis, is that the laser devices should produce some amount of pain relief as tested with a commonly used dental nerve testing device.
Interventions
Intervention used in this study will be laser and Light-emitting diode (LED) therapy, delivered by the Principal Investigator (AHPRA registered general dentist). Participants will be selected based on the appropriateness and health of the selected teeth (premolars). These teeth will be required to have no previous injury, decay, or dental work completed on it. The gum health will also need to be healthy (no bleeding on probing, probing depths less than 3mm, no recession, no exposed root surface
Intervention used in this study will be laser and Light-emitting diode (LED) therapy, delivered by the Principal Investigator (AHPRA registered general dentist). Participants will be selected based on the appropriateness and health of the selected teeth (premolars). These teeth will be required to have no previous injury, decay, or dental work completed on it. The gum health will also need to be healthy (no bleeding on probing, probing depths less than 3mm, no recession, no exposed root surface) Participants will be required to attend 4 appointments for the four light delivery sources. Each appointment, one light source will be used. The four used are of various wavelengths: 660nm, 808nm, 904nm, and multiwavelength (range of 660-1000nm). These will be delivered to the selected tooth, front (buccal) and back (palatal) for 30 seconds each. There is no washout period, and four sessions can be spaced out according to participant’s convenience. All four sessions will be scheduled prior to starting in the appointment calendar used at site (Oasis, Henry Schein One software). The intervention will delivered face to face within a clinical setting utilising appropriate Personal protective equipment and following manufacturer instructions. Each participant will then be tested for pulpal sensitivity using a commonly used dental equipment called Electric pulp test. The reading will be recorded. Upon this, one laser per session will be used. 4 lasers are: 660nm, 808nm, 904nm, Combined (700nm, 900nm, 1000nm). Each laser is placed next to the tooth, front and back of it, for 30 seconds each, totalling 60 seconds, Upon completion, 2 minutes later, the electric pulp test is used to measure the reading again and this is recorded.
