EFFECTS OF PHASE I PERIODONTAL THERAPY IN CIGARETTE SMOKERS, HEATED TOBACCO PRODUCT USERS, DUAL USERS, AND NON-SMOKERS

6. november 2026 opdateret af: Özge Uzuner Bilgiç, Cyprus Health and Social Sciences University

EVALUATION OF THE EFFECTS OF CONVENTIONAL CIGARETTE SMOKING, HEATED TOBACCO PRODUCT USE, AND DUAL USE ON PHASE I PERIODONTAL THERAPY OUTCOMES

This prospective, comparative clinical study aims to evaluate the periodontal status and response to Phase I periodontal therapy among conventional cigarette smokers, heated tobacco product users, dual users of conventional cigarettes and heated tobacco products, and non-smokers.

The study includes systemically healthy individuals aged 18-35 years diagnosed with generalized gingivitis. Participants are categorized into four groups according to their existing tobacco use habits.

Periodontal assessments include full-mouth plaque score (FMPS), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL). All participants receive conventional Phase I periodontal therapy and standardized oral hygiene instructions as part of routine periodontal care.

Clinical periodontal parameters are evaluated at baseline and at one and three months following treatment. The study aims to compare periodontal outcomes and changes over time among the four tobacco use groups.

Eksperimentel: Phase I Periodontal Therapy

Participants aged 18-35 years diagnosed with generalized gingivitis receive Phase I periodontal therapy and standardized oral hygiene instructions. Participants are categorized into four subgroups according to their pre-existing tobacco use status: conventional cigarette smokers, heated tobacco product users, dual users, and non-smokers. Periodontal parameters, including full-mouth plaque score (FMPS), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL), are assessed at baseline and at 1 and 3 months following treatment.

All participants diagnosed with generalized gingivitis will receive conventional non-surgical Phase I periodontal therapy, including professional scaling and standardized oral hygiene instructions. Participants will be assessed at baseline and at one and three months following treatment. Periodontal treatment outcomes will be evaluated using full-mouth plaque score (FMPS), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL). The same treatment approach will be applied across all four tobacco use groups.

Foranstaltningsbeskrivelse
Tidsramme
Change in Full-Mouth Plaque Score (FMPS)
Tidsramme: Baseline, 1 month, and 3 months after treatment

Full-mouth plaque score (FMPS) will be assessed using the O'Leary plaque control record. The presence or absence of dental plaque will be recorded at four surfaces per tooth without a disclosing agent. FMPS will be expressed as the percentage of plaque-positive surfaces. Changes in FMPS following Phase I periodontal therapy will be compared among the four tobacco use groups.

Tidsramme
Change in Bleeding on Probing (BOP)
Tidsramme: Baseline, 1 month, and 3 months after treatment

Bleeding on probing (BOP) will be assessed using the Ainamo and Bay Gingival Bleeding Index. Bleeding will be recorded dichotomously as present (1) or absent (0) following gentle periodontal probing. BOP will be expressed as the percentage of bleeding-positive sites. Changes in BOP following Phase I periodontal therapy will be compared among conventional cigarette smokers, heated tobacco product users, dual users, and non-smokers.

Foranstaltningsbeskrivelse
Tidsramme
Change in Probing Pocket Depth (PPD)
Tidsramme: Baseline, 1 month, and 3 months after treatment

Probing pocket depth (PPD) will be measured in millimeters using a UNC-15 periodontal probe at six sites per tooth (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, and distolingual). PPD is defined as the distance from the gingival margin to the base of the gingival sulcus or periodontal pocket. Changes in PPD following Phase I periodontal therapy will be evaluated at baseline, one month, and three months and compared among the four tobacco use groups.

Baseline, 1 month, and 3 months after treatment
Change in Clinical Attachment Level (CAL)
Tidsramme: Baseline, 1 month, and 3 months after treatment

Clinical attachment level (CAL) will be measured in millimeters using a UNC-15 periodontal probe at six sites per tooth (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, and distolingual). CAL is defined as the distance from the cementoenamel junction (CEJ) to the base of the gingival sulcus or periodontal pocket. Changes in CAL following Phase I periodontal therapy will be assessed at baseline, one month, and three months and compared among the four tobacco use groups.
