The temporomandibular joint and the muscles are part of a kinematic chain, which can be influenced, inter alia, by the spine and the shoulder girdle. By this kinematic chain it becomes clear that complaints of one body level may affect another. To assess the effects of posture on the temporomandibular system frontal full body photographs are used. Good reproducibility of those photographs is essential for drawing valid conclusions regarding posture. The reproducibility of the frontal body static photographs was investigated by comparing multiple photographs over time. A questionnaire was used for the determination of relevant secondary objectives. To display the measured values, the software Image J was used and the evaluation of the questionnaire was carried out with SPSS. Objective: The objective of this study is to verify whether repeated photographs of the body statics conducted on volunteer students, always give the same result and, where appropriate, conclusions about the posture and mutual influence of chewing and the musculoskeletal system using the kinematic chain can be drawn. The study was conducted at the Department of Orthodontics at the University Dental Clinic in Vienna. The accumulation of data extended over a period of 1 years (July 2014 to January 2016). A total of 15 female and 20 male participants took part in the open monocentrically scaled study. The average age of the participating students of the 7th semester was 25.6 years. Methodology: For data collection 3 frontal body static photographs were carried out for every volunteer. A special questionnaire was issued to the study participants with 15, partially open and closed questions to evaluate the actual being, presence of TMJ noises, bruxism, current or past braces and pain or discomfort in the locomotor system. Overall, participants were invited to three photo dates at the University Clinic. The photographs were carried out in a period of one week; the first photo shoot "T0", the second photo shoot, "T1", 2 days after "T0", and the 3rd photo shoot, "T2", 1 week after the first appointment. For each of these dates the volunteers were asked to fill out the same questionnaire again. Before analyzing the collected data from the study, subjects which could not meet the deadline for the photo dates or did not meet the criteria for this study were excluded. The aim of this selection was to reduce the sources of error to a minimum. It was possible to evaluate 89 photographs statistically. An information sheet for consideration of important details such as the positioning in front of the grid panel served the volunteers as a guide. For collection of the measured values the softwares ImageJ and SPSS were used. The results were displayed by using the Bland Altman chart. The frontal body static photographs at T0 were compared with T1 and T2. In addition, the photographs were compared at T1 to T2. By using the Bland Altman chart it was possible to demonstrate the reproducibility of the images graphically. Results: The differences between the angles and between defined body points and a reference grid (W1,2,3,5) ranged between -0.87 and +0.45. Slight differences of -0,74cm to +0,45cm were found for the distance measurements W3,4,5,6,7. Conclusion: The frontal shots of the body statics were taken at 3 different time points by one investigator. The results indicate that a good reproducibility can be achieved, conclusions regarding posture can potentially be drawn from a single photograph. However, a larger sample as well as photographs from other perspectives such as lateral body static views would expand the data available and may allow for more conclusions.
