Overview
The aim of the study is to evaluate the relationship between professional experience and grip strength, pain threshold and anxiety level in dentists. As a result of the results obtained, we aim to contribute an original study to the literature and to increase awareness by informing the dentists participating in the study.
Detailed description
Our hypotheses:
H1: Professional experience has an effect on hand grip strength in dentists. H2: Professional experience has an effect on finger grip strength in dentists. H2: Professional experience has an effect on pain in dentists. H3: Professional experience has an effect on anxiety level in dentists.
The unique value of our study is that it is the first study to examine the relationship between dentists' professional experience and grip strength, pain, and anxiety. When we look at the literature, we have not found any studies examining the effect of dentists' professional experience on grip strength and pain. In the study, grip strength, pain threshold, and forearm grip strength will be evaluated. Grip strength will be assessed with a Jamar hand dynamometer, pinch grip with a Baseline brand pinchmeter, pain threshold with a dolorometer, and forearm grip strength with a handheld dynamometer. Anxiety will be assessed with the Beck Anxiety Questionnaire.
Interventions
- Other Grip strength assessment
Jamar hand dynamometer, recommended by the American Hand Therapists Association and accepted as the gold standard in many studies due to its high validity and reliability, will be used to measure hand grip strength. Pinchmeter (Baseline Mechanical Pinch Gauge) will be used to measure fine grip strength. Hand grip and finger grip strength measurements will be made in the recommended standard position of sitting, shoulder adduction and neutral rotation, elbow 90 degrees flexed, forearm in mid-rota - Other Forearm muscle strength assessment
Wrist isometric muscle strength assessment will be performed with a handheld dynamometer (Lafayette Instrument Company, Lafayette, Indiana, USA). Patients will be placed in the supine, prone and sitting positions using the positions required for the fine muscle test method defined by Lovett and will be performed without compensatory movements. Wrist flexor and extensor muscles will be assessed. The values obtained with isometric contraction will be recorded in kg. Muscle strength measurements wi - Other Pain threshold assessment
Pain sensitivity to pressure will be assessed with a pain measuring device called an algometer. The Baseline Dolorimeter brand algometer will be used in the assessment. 3 measurements will be taken from the "midpoint of the upper trapezius muscle" and "C7" points between the lateral edge of the acromion and C7. The areas will be marked before the measurement. The algometer will be placed perpendicular to these points. The patients will be asked to report the moment they first felt the pain and 3 - Other Anxiety level assessment
The anxiety level will be determined with the Beck Anxiety Inventory. The Beck Anxiety Inventory is a scale developed by Aaron T. Beck (1988). This scale consists of 21 questions. For each item, the patient is asked to report how he/she has felt during the past week. The items are scored as 0, 1, 2 or 3. The score range is between 0-63. For the total score, \< 21 is considered mild, 22-35 is considered moderate, and \> 36 is considered severe. The Turkish validity study of the Beck anxiety scal
