Evaluation of Gingival Tissue Protein Levels of Serum Amyloid A Family Members
The primary aim of this study is to determine the serum amyloid A (SAA) family protein levels in gingival tissue samples obtained from periodontally healthy and periodontitis patients and to evaluate their relationship with periodontal status. Additionally, the study aims to assess the potential effect of smoking on the amount of SAA proteins in gingival tissue.
Following ethical committee approval, a total of 108 individuals aged 18-65 years who attending to the Department of Periodontology, Biruni University Faculty of Dentistry, will be included in the study. The study groups will consist of 27 non-smoking individuals with periodontally healthy tissue, 27 smoking individuals with periodontally healthy tissue, 27 non-smoking individuals with stage III grade B periodontitis, and 27 smoking individuals with stage III grade C periodontitis. The non-smoking groups will include individuals who have never smoked, while the smoking groups will include individuals who, according to patient statements, have smoked at least 10 cigarettes per day for more than five years.
All participants will be informed about the study and their written consent will be obtained. Plaque score, probing depth, gingival margin position, clinical attachment level, and bleeding on probing will be measured by a calibrated investigator. Gingival tissue samples from periodontally healthy individuals will be collected during planned tooth extraction or periodontal surgical procedures such as gingivoplasty, gingivectomy, or clinical crown lengthening, independent of the study. Only gingival tissues that would otherwise be discarded as medical waste during routine treatment will be used. In individuals with periodontitis, granulation tissue removed during subgingival instrumentation as part of non-surgical periodontal treatment is planned for use. No additional tissue will be removed from the periodontal pocket wall or junctional epithelium for research purposes; the scope of the clinical procedure will not be expanded if suitable tissue cannot be obtained.
Gingival tissue samples will only be collected initially, stored at -80°C until the day of analysis, and evaluated using the ELISA method.

Población de estudio
Adults aged 18-65 years attending the Department of Periodontology, Faculty of Dentistry, Biruni University, who meet the study eligibility criteria. A total of 108 participants will be included in four groups of 27: periodontally healthy never smokers, periodontally healthy smokers, never smokers with stage III grade B periodontitis, and smokers with stage III grade C periodontitis. Periodontally healthy participants must have an independent clinical indication for tooth extraction or periodontal surgery during which gingival tissue would otherwise be discarded.

Periodontally Healthy Non-smokers
Twenty-seven adults aged 18-65 years who have never smoked, with periodontal health on an intact periodontium, probing depths ≤3 mm, bleeding on probing at <10% of sites, no radiographic bone loss, and no history of periodontal disease. |
|
Periodontally Healthy Smokers
Twenty-seven adults aged 18-65 years who report smoking ≥10 cigarettes per day for more than 5 years, with periodontal health on an intact periodontium, probing depths ≤3 mm, bleeding on probing at <10% of sites, no radiographic bone loss, and no history of periodontal disease. |
|
Stage III Grade B Periodontitis
Twenty-seven adults aged 18-65 years who have never smoked and have stage III grade B periodontitis. Clinical criteria include clinical attachment loss ≥5 mm at ≥2 nonadjacent teeth, radiographic bone loss extending to the middle third of the root or beyond, loss of ≤4 teeth due to periodontitis, probing depths ≥6 mm, vertical bone loss ≥3 mm, and ≥20 remaining teeth. The percentage radiographic bone loss-to-age ratio will be 0.25-1.0. |
|
Stage III Grade C Periodontitis
Twenty-seven adults aged 18-65 years who report smoking ≥10 cigarettes per day for more than 5 years and have stage III grade C periodontitis. Clinical criteria include clinical attachment loss ≥5 mm at ≥2 nonadjacent teeth, radiographic bone loss extending to the middle third of the root or beyond, loss of ≤4 teeth due to periodontitis, probing depths ≥6 mm, vertical bone loss ≥3 mm, and ≥20 remaining teeth. The percentage radiographic bone loss-to-age ratio will be 0.25-1.0; grade C classification will be based on smoking ≥10 cigarettes per day as a grade modifier. |
