This study aimed to compare the distribution of subgingival periodontal pathogens following non-surgical periodontal therapy in smoking and non-smoking people with periodontitis. The main question it aims to answer is: - Does smoking affect the results of non-surgical periodontal treatment on subgingival flora in participants with periodontal disease? Researchers performed non-surgical periodontal therapy on 48 participants with stage III/IV periodontitis and recorded clinical measurements. They obtained subgingival plaque samples from periodontal pockets at the onset and after four weeks of treatment, determining the level of periodontopathogens using a polymerase chain reaction-based method.

Primary | Change in levels of periodontopathogens in subgingival plaque after non-surgical periodontal therapy in smokers and non-smokers with stage 3/4 periodontitis | The baseline levels of periodontopathogens (P. gingivalis, A. actinomycetemcomitans, T. forsythia, F. nucleatum, P. intermedia, T. denticola, P. micra, C. rectus, E. nodatum, Capnocytophaga spp, and E. corrodens), post-treatment levels, and elimination levels with treatment were evaluated using multiplex polymerase chain reaction (PCR) analysis.The observed rates of microorganisms were assessed by determining six main levels.
0: No colouring (<1% no bacteria) Very light-colored staining (Determination of bacteria from 1% to 20%). Light colored staining (Determination of bacteria from 21% to 40%), Moderate colored staining (Determination of bacteria from 41% to 60%), Dark colored staining (Determination of bacteria from 61% to 80%), Very dark-colored staining (Determination of bacteria from 81% to 100%). |
Baseline and four weeks after the periodontal therapy. | |
Secondary | Change in clinical attachment level (CAL) | CAL is the main clinical parameter indicating the severity of periodontal disease. CAL measurements were performed on six different surfaces of each tooth (disto-buccal/labial, mid-buccal/labial, mesio-buccal/labial, disto-lingual, mid-lingual, and mesio lingual) by using a periodontal probe (Williams probe; Chicago, IL) and average value was calculated in millimeters.
CAL 1-2 mm: Stage 1 periodontitis CAL 3-4 mm: Stage 2 periodontitis CAL = 5 mm: Stage 3/4 periodontitis |
Baseline and 4 weeks after periodontal therapy | |
Secondary | Change in probing depth (PD) | PD is one of the clinical parameters indicating the severity of periodontal disease. PD measurements were performed on six different surfaces of each tooth (disto-buccal/labial, mid-buccal/labial, mesio-buccal/labial, disto-lingual, mid-lingual, and mesio lingual) by using a periodontal probe (Williams probe; Chicago, IL) and average value was calculated in millimeters.
PD = 4 mm: Stage 1 periodontitis PD = 5 mm: Stage 2 periodontitis PD = 6 mm: Stage 3/4 periodontitis |
Baseline and 4 weeks after periodontal therapy | |
Secondary | Change in gingival index (GI) scores | GI is a clinical parameter indicating the severity of gingival inflammation. GI scores were noted for four different surfaces of each tooth (buccal, distal, mesial and lingual) and average value was calculated.
0 = normal gingiva; = mild inflammation: slight change in color, slight edema, no bleeding on probing; = moderate inflammation: redness, edema, and glazing, or bleeding on probing; = severe inflammation: marked redness and edema, tendency toward spontaneous bleeding. |
Baseline and 4 weeks after periodontal therapy | |
Secondary | Change in plaque index (PI) scores | PI is a clinical parameter indicating the severity of dental plaque accumulation and oral hygiene habits of individuals. PI scores were noted for four different surfaces of each tooth (buccal, distal, mesial and lingual) and average value was calculated.
0 = No plaque = A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may be seen in situ only after application of disclosing solution or by using the probe on the tooth surface. = Moderate accumulation of soft deposits within the gingival pocket, or the tooth and gingival margin which can be seen with the naked eye. = Abundance of soft matter within the gingival pocket and/or on the tooth and gingival margin. |
Baseline and 4 weeks after periodontal therapy | |
Secondary | Change in Bleeding on Probing (BOP) | BOP is one the clinical parameters indicating the severity of gingival inflammation. BOP were noted as positive or negative for four different surfaces of each tooth (buccal, distal, mesial and lingual) and average positive value was calculated in %. | Baseline and 4 weeks after periodontal therapy |
