Objectives: Musculoskeletal problems have been a concern in dentists for years. The aim of this study is to evaluate the relationship between posture and musculoskeletal pain in dentists.

Working in an extremely challenging posture, performing movements that require force, and sitting or standing for a long time during dental practices are effective in the formation of musculoskeletal pain. Musculoskeletal pain; is caused by disorders affecting anatomical structures that provide structural support to our body, such as muscles, tendons, ligaments, cartilage, bones, and joints. Literature information shows that an average of 64% to 93% of dentists complain of musculoskeletal pain throughout their professional life.

Dentists often exhibit a negative posture characterized by neck flexion and shoulder abduction in order to provide a better field of view when treating their patients. Flattening of the cervical lordosis due to forward bending of the head and neck; Over time, it causes fatigue in the muscles in the neck and shoulder region, decrease in blood flow, pain, and ultimately protective muscle contractions. These irregularities in the muscles due to repetitive cumulative traumas can increase the force on the spinal discs of the neck and cause inevitable musculoskeletal diseases in the future. Similarly, a decrease in lumbar lordosis, right lateral flexion of the lumbar vertebrae, and leftward tilt of the thoracic vertebrae are characteristic positions during patient treatment in physicians who constantly sit and work, and studies have shown that there is a positive and significant correlation between this position and low back pain.

According to the definition of the Posture Committee of the American Academy of Orthopedic Surgeons, posture is the balanced and proper arrangement of skeletal elements in order to protect the body from deformations and prevent injury. Physiologically and biomechanically good posture is a posture that provides maximum efficiency in the body with minimum effort. It is important for a good posture that the four basic curvatures of the human spine, known as cervical and lumbar lordosis, thoracic and sacral kyphosis, are in harmony. Improper postural posture; accelerates the wear and tear in the vertebrae, discs, muscles, and ligaments, which causes pain. Therefore, the evaluation of posture is important in dentists.

Even in the best working position, dentists must have more than 50 muscles active in order to keep their body positions stable against gravity. Physicians generally lose their postural awareness during treatment shortly after starting treatment. During the treatment, they work in an inappropriate posture for a long time, neglecting their own health, mostly considering the treatment applications and the comfort of the patients. It is very important for physicians to be aware of the factors that cause musculoskeletal system problems and to learn to work in the right posture in order to maintain their health and practice their profession for a long time.

Posture evaluation of individuals is evaluated based on some reference points in the body. In this way, the relationship of body parts with each other and with gravity is compared with normal anatomical features, and deviations and differences are determined. The gold standard method in standard posture analysis is radiographic analysis. However, the use of radiography is undesirable due to the radiation it contains. The Spinal Mouse, which is an important tool in the measurement of posture correctness, is a device with mouse-shaped wheels that detects the angles and position of the spine and transfers them to the computer environment without the need for radiography and is a safe and non-invasive tool. It detects the curvature of the spine, its anatomical structure, and movements in the sagittal and frontal planes. It is an easy-to-use, fast and practical measuring device. Compared to radiography, it is important that it does not contain radiation and is non-invasive. The reliability and validity studies of the device have been carried out, and it provides quantitative data in order to obtain quick information about the posture. The raw data of the wireless and handheld mouse is transferred to the computer via Bluetooth and the data is evaluated in the computer environment. In this study, it is planned to obtain quantitative data about the postures of dentists by using the spinal mouse. In the literature review, only one study reported that there was a positive correlation between spinal mouse data and musculoskeletal pain in the evaluation of 1st, 3rd, and 5th-grade students using a spinal mouse. However, there is no study that evaluates the relationship between working hours, working positions, posture, and musculoskeletal pain in dentists working in different departments and compares them with the data of dentistry students who have just started their profession.

In light of all this information, the aim of this study is to evaluate the relationship between posture and musculoskeletal pain in dentists.
