This study aims to investigate the effect of clear aligners and traditional brackets on the nutritional status of orthodontic patients. With the increasing demand for more aesthetic and comfortable orthodontic appliances among adults, clear aligner treatment has gained popularity as an alternative to traditional fixed appliances. However, limited research has been conducted to evaluate the impact of clear aligners on dietary habits and nutrition. The study will include adult participants undergoing orthodontic treatment with either clear aligners or traditional brackets. Anthropometric measurements, dietary assessments, and oral health impact evaluations will be conducted to assess the nutritional status of the participants. The findings of this study will contribute to a better understanding of the influence of orthodontic appliances on nutrition and guide clinicians in providing comprehensive care to orthodontic patients.

RECRUITINGChewing Ability Assessment
Chewing ability will be evaluated using a questionnaire to assess both subjective and objective aspects. The questionnaire will consist of open-ended and closed-ended questions to determine individuals' chewing difficulties. Open-ended questions will focus on identifying specific foods that present challenges during chewing and the strategies employed to consume these foods. In subsequent follow-up interviews, closed-ended questions will be used to evaluate the ability to chew the previously listed foods, with response options such as "easy to chew," "experiencing some difficulty," and "experiencing great difficulty/cannot chew at all." If participants indicate experiencing slight or significant difficulty chewing at least two of the hard foods and four of the soft foods, it will be considered indicative of chewing difficulties. This assessment will provide valuable insights into the participants' chewing function and its impact on their dietary habits and oral health.
Time frame: Day 1
Oral Health Impact Profile-14 (OHIP-14)
The Oral Health Impact Profile-14 (OHIP-14) is a measurement tool developed to assess the impact of oral and dental health on individuals. It consists of 14 questions, and each question is rated on a scale of 0 to 4, with response options defined on a Likert scale as "0=never, 1=rarely, 2=sometimes, 3=often, and 4=always." The total score of OHIP-14 ranges from 0 to 56. A higher total score indicates increased severity of problems and decreased quality of life. In this study, OHIP-14 will be administered to participants to evaluate the impact of oral health on their daily functioning, well-being, and quality of life.
Time frame: Day 1
Physical Activity Level
Physical activity levels of participants will be assessed using the International Physical Activity Questionnaire (IPAQ) short form. The IPAQ was developed with the support of the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), and its validity and reliability study was conducted in Turkey in 2010 by Sağlam et al. Individual Metabolic Equivalent Task (MET) scores will be calculated based on the IPAQ protocol to categorize participants into "low, moderate, and high activity levels." Total scores ranging from 0 to 600 will be classified as "low level," scores between 600 and 1500 or 3000 (depending on the number of days of moderate and vigorous physical activity per week) will be classified as "moderate level," and scores equal to or above 1500 or 3000 (depending on the number of days of moderate and vigorous physical activity per week) will be classified as "high level."
Time frame: Day 1
Height Measurement
The participants' height will be measured using standard procedures with the participants standing upright, heels together, head in an upright position, and looking straight ahead.
Time frame: Day 1
Body Composition
Body composition analysis will be performed with the Tanita DC-360 device that performs bioelectrical impedance analysis (BIA). The analysis report includes body weight (kg), body water mass (kg), body fat mass (kg) and body muscle mass (kg). This method is non-invasive and provides body composition data in less than 1 minute of measurement.
Time frame: Day 1
Waist Circumference
Waist circumference will be measured using a flexible tape measure placed horizontally around the smallest circumference between the lower rib and the iliac crest, parallel to the floor passing through the navel.
Time frame: Day 1
