Exclusion criteria
Exclusion criteria: Patients will be excluded from the study if they do not meet the diagnostic criteria for generalized periodontitis stage III or IV, grade B. Additional exclusion criteria: - Acute treatments - Periodontal therapy in the last 12 months - Antibiotic medication in the last 12 months - Antibiotic medication or prophylaxis required for periodontal therapy - Systemic diseases or medication intake that may have an influence on periodontal parameters (e.g. type II diabetes mellitus, cardiovascular diseases or bisphosphonate medication) - Smoking or tobacco consumption within the last 5 years - Down syndrome or HIV/AIDS diagnosis - Pregnancy or breastfeeding - Orthodontic treatment is required - Carious lesions are present - Oral piercings - Dental student or dentist - Cognitive deficits - Participation in a dental study within the last 6 months - Withdrows and drop-outs - Poor compliance
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is to achieve a mean reduction in pocket probing depth of 0.5mm (Stein et al., 2021; Wennström et al., 2005). For the purposes of analysis, teeth are divided into two categories: those with and without fixed dental restorations. Measuring instrument: Florida Probe (computerized periodontal probing) Time of measurement: before non-surgical periodontal therapy, 3 months and 6 months after non-surgical periodontal therapy | — |
Secondary
| Measure | Time frame |
|---|---|
| - measurement of marginal fit of crowns (Holmes et al., 1989) - median clinical attachment level - percentage of sites showing pocket probing depth 4.0mm - 5.9mm - percentage of sites showing pocket probing depth =6.0mm - median pocket probing depth - median gingival margin - median bleeding on probing - degree of furcation - plaque index - papilla bleeding index - periodontal inflamed surface area (PISA) - qualitative and quantitative bacterial load - antibiotic sensitivity testing (antibiogram) - specific blood parameters - specific inflammation indices | — |
