Plain English Summary
Background and study aims
Periodontitis is a common dental disease which causes bleeding of the gums, gum shrinkage and bone loss around the teeth which may result in tooth loss if the condition is untreated. Tooth loss can impact on quality of life as it may become more difficult to chew and missing teeth can make people self-conscious of their appearance and less confident. Routine treatments for periodontal disease may include surgical or non-surgical procedures, followed by regular maintenance treatment. There is strong evidence that structured maintenance treatment and good oral hygiene help to maintain gum health and prevent tooth loss. Supportive periodontal maintenance treatment comprises of cleaning and plaque removal around the gum margin of affected teeth. This treatment is usually performed with powered ultrasonic scalers, although hand instruments can also be used. There are two types of ultrasonic device, magnetostrictive devices and piezoelectric scaler devices. One of the main differences between the two types of device is the way the ‘dental cleaning’ tip of the device vibrates on the tooth surface. The other difference between each device is the amount of water that is required during operation. For the magnetostrictive scaler, a large amount of cold water only is required. This is due to the handpiece heating during operation and needing cooling. For the piezoelectric device, the vibration is only at the cleaning tip, which means the handle doesn’t need cooling. This device also has the ability to gently heat the water flowing through it. The aim of this study is to compare patient experience between the use of a piezoelectric ultrasonic scaler and a magnetostrictive ultrasonic scaler during regular maintenance treatment for patients who have periodontal disease.
Who can participate?
Patients aged 18 and over who are susceptible to periodontal disease
What does the study involve?
Participants are randomly allocated to receive supportive periodontal treatment using either the piezo or magnetostrictive scaler with either room temperature or warm water on the left and right side of the mouth. Discomfort, noise and vibration during treatment are measured. Following the end of the study, the participants remain under the care of their Dental Practitioner and there is no change to their routine care as a result of participating in the study.
What are the possible benefits and risks of participating?
There are no direct benefits to the participants from taking part in the study, but they may help provide dental professionals with a greater understanding of patient experience during dental cleaning using scaling devices. The risks to the participants from taking part in the study are no greater than for standard tooth cleaning treatment using dental scaling devices. Participants may experience some pain or discomfort following treatment, but this is to be expected following this type of treatment and will be of short duration.

| Scientific title | To compare patient experience using two ultrasonic scalers, a magnetostrictive stack scaler with a piezoelectric scaler, in the maintenance of periodontal stability |
| Study hypothesis | 1. To determine patient experience (pain/discomfort, vibration, noise) during ultrasonic tooth scaling as part of a periodontal maintenance visit using a piezo-device compared to a magnetostrictive-device with room temperature water used in both devices for irrigation. The primary outcome measure is discomfort 2. To determine patient experience (pain/discomfort, vibration, noise) during ultrasonic tooth scaling as part of a periodontal maintenance visit using a piezo-device irrigated by warm water compared to a magnetostrictive-device with room temperature water for irrigation. The primary outcome measure is discomfort |

| Condition | Periodontal disease |
| Intervention | Eligible participants will be randomly allocated to receive one of 4 treatment regimens, according to a predetermined randomisation schedule (2 treatments, 1 study visit – split mouth). The allocated treatment regimen will be assigned in order of participants being recruited. The treatment procedures are as follows: A1: right side: Tigon+ with room temperature water (~20-22°C), left side: Cavitron with room temperature water (~20-22°C) A2: right side: Cavitron with room temperature water (~20-22°C), left side Tigon+ with room temperature water (~20-22°C) B1: right side: Tigon+ with warm water (~36-37°C), left side: Cavitron with room temperature water (~20-22°C) B2: right side: Cavitron with room temperature water (~20-22°C), left side: Tigon+ with warm water (~36-37°C) Supportive periodontal treatment will be performed on both sides of the mouth using either the piezo or magnetostrictive scaler on the left or right side of the mouth depending on the treatment regimen the participant is assigned to. In all participants, the left side of the mouth will always be assessed first for consistency. There will only be one study visit for the participant to attend to complete the study. Both treatments will be performed at the same visit on the allocated side of the mouth. Following the end of the study, the participants will remain under the care of their Dental Practitioner and there will be no change to their routine care as a result of participating in the study. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure | Patient experience (pain/discomfort, vibration, noise) during ultrasonic tooth scaling comparing the devices with the use of room temperature water. Measured using VAS score lines immediately following treatment of each side of the mouth. |
| Secondary outcome measures | Patient experience (pain/discomfort, vibration, noise) during ultrasonic tooth scaling using a piezo-device irrigated by warm water compared to a magnetostrictive-device with room temperature water for irrigation. Measured using VAS score lines immediately following treatment of each side of the mouth. |
