Interventions

Group 1: Patients are given a one-off routine dental examination at an oral surgery practice. The following oral hygiene parameters are measured: Silness and Löe plaque index (PI) – all tooth surfaces
II + IV quadrant vestibular) Probing depth (4-point measurement, mm) and bleeding on probing (BOP) (yes/no)

Design outcomes

Primary

MeasureTime frame
Patients are told about the planned study in a telephone conversation and called in for a routine dental examination. After the patient briefing, patients are given a data protection policy, patient information leaflet and consent form. If patients consent to take part in the study, the dental examination is performed and clinical parameters including probing depths, BOP, PI and MAPI are measured. The probing depth of gingival pockets is determined using a periodontal probe introduced into the sulcus. Measurements are made parallel to the long axis with contact to the root surface or implant at at least four points (mesiobuccal, buccal, distobuccal and oral) at a pressure of approximately 0.25 N. If signs of inflammation, such as a putrid exudate, increased probing depths or bleeding on probing, are present, x-ray investigations can be used to differentiate between peri-implantitis and peri-implant mucositis. The patient’s oral hygiene is then recorded using the plaque index. The Silness and Löe plaque index evaluates the level of plaque and plaque thickness in the region of the cementoenamel junction, including the sulcus, tooth surface and gingival margin. This investigation is performed using a mirror and probe on all previously dried tooth surfaces without staining. After staining the plaque with a plaque discloser, the investigator assesses whether plaque is present in the approximal space (MAPI). This assessment is made lingually in the 1st and 3rd quadrants and vestibularly in the 2nd and 4th quadrants. An x-ray is only performed if abnormalities are found on clinical examination. In this study, x-ray images are evaluated retrospectively only. Images are analysed digitally using the Sidexis XG software package from Dentsply Sirona. In the event of abnormal clinical findings, the S3 guideline permits control x-rays to be made after an observation period of at least three years. Control x-rays are taken in consultation with and after briefing the patient. All x
