Brief summary

A total of 318 patients applying to Bolu Abant İzzet Baysal University will be included in the study. Based on anamnesis, radiographic examination, and the 2018 classification of periodontal diseases, the participants will be categorized into three groups: periodontal health (n=106), gingivitis (n=106), and periodontitis (n=106). Information regarding participants' coffee consumption habits and their daily coffee intake will be collected. Clinical parameters to be measured will include plaque index, gingival index, bleeding on probing, gingival recession, and clinical attachment level. The frequency of coffee consumption will be evaluated as daily, 1-2 times per week, 3-4 times per week, once per month, twice per month, and once per year. The amount of coffee consumed at a single occasion (cup, glass, mug, etc.) will also be recorded. In caffeinated coffee consumption, the preference for weak, moderate, or strong coffee, as well as consumption with milk, condensed milk, sugar, honey, or sweeteners will be assessed. For Turkish coffee, the consumption pattern will be categorized as unsweetened, moderately sweetened, or sweetened.

Design outcomes

Primary

MeasureTime frameDescription
periodontal pocket depthBaselinephysical methods to measure the distance from the bottom of a pocket to a reference line, usually the gingival margin or the cemento-enamel junction.
bleeding on probingbaselineTo test for bleeding after probing, the probe is carefully introduced to the bottom of the pocket and gently moved laterally along the pocket wall. + is maximum and - is minimum.
Frequency of consumption of coffeebaselinethe frequency of fermented foods is measured. The foods questioned were evaluated using a 7-point Likert-type frequency form (every day, 3-4 per week, 1-2 per week, 2 per month, 1 per month, never). In addition, the amounts of foods consumed each time were recorded, and the daily consumption amounts were obtained by dividing them by the frequency of consumption.

Secondary

MeasureTime frameDescription
plaque indexbaselinean index for estimating the status of oral hygiene by measuring dental plaque that occurs in the areas adjacent to the gingival margin. 0 is minimum and 3 is maximum. The situation worsens as the score increases.
gingival indexbaselineThe Gingival Index (GI) scores each site on a 0 to 3 scale, with 0 being normal and 3 being severe inflammation characterized by edema, redness, swelling, and spontaneous bleeding. 0 is minimum and 3 is maximum. The situation worsens as the score increases.
clinical attachment levelbaselineThe clinical attachment level (CAL) and radiographically assessed bone levels are used to assess the loss of periodontal tissue support in periodontitis, a chronic, multifactorial inflammatory disease of the periodontium.
