Evaluation of Nutritional Habits, Oral Hygiene Status, Relationship Between Dental Caries and Periodontal Condition

Patients who will visit the Periodontology Clinic will be consecutively enrolled in the study by one of the researchers (D.O.S), if they meet the following criteria:

• No smoking.
• Not having undergone dental scaling and root surface correction treatment in the last 6 months.
• Presence of at least 20 teeth in the mouth.
• Not pregnant and/or breastfeeding.
• Patients taking drugs known to alter bone metabolism or having established degenerative bone diseases (hyperparathyroidism, osteoporosis).
• Patients who have not received antibiotics, nonsteroidal anti-inflammatory drugs, or corticosteroids for >2 weeks in the 3 months prior to the study.
• Patients who agree to participate will undergo an oral examination and answer a questionnaire survey.

Periodontal Examination: Routine clinical periodontal parameters such as plaque index (PI), gingival index (GI), Probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment levels, and gingival recession will be recorded in all patient groups before treatment [13]. Individuals will be classified according to the 2017 classification [14].

After 30 seconds, at six locations per tooth, a calibrated clinical researcher will measure the probing depth (PD), which is the distance between the free gingival margin and the pocket depth, the clinical attachment level (CAL), which is the distance between the cement-enamel attachment and the pocket depth, and the bleeding on probing (BOP) [15]. According to the World Workshop on Classification and Conditions of Periodontal and Peri-implant Diseases 2017, periodontitis will be identified [14]. The PD severity index will be calculated as the percentage of teeth with PD higher than or equal to 4 mm in two or more interproximal locations [16]. Mean PD, CAL, and BoP will also be obtained. Additionally, the quantity of teeth will be recorded.

To the individuals included in the research; A questionnaire consisting of 16 questions including demographic data of individuals, the number of daily snacks, daily carbohydrate-containing food and sugary drink consumption frequency, tooth brushing frequency, and duration, education level, and oral care habits will be filled [17].
