Introduction: Sarcopenia is a prevalent condition characterized by decrease in muscle strength and loss of body function which result from the decrease of muscle mass in older age. In 2014, the Asian Working Group for Sarcopenia developed the diagnosis criterion for sarcopenia. The measurements were changed to accommodate for the physical characteristics of asians. The loss of muscle mass increases after age 40 and decreases by 8 percent every 10 years. After age 70 this number is increased to 15 percent every 10 years. Goal: Assess the prevalence of sarcopenia among men by comparing body height and mass Materials and Methods: The study included 196 older men aged 40 and above chosen by random sampling from the geriatric and rehabilitation cabinets of the Mongolian National Gerontology Center.
Sarcopenia diagnosis was made based on the criteria from the Asian Working Group for Sarcopenia using methods by Janssen I and others to compare body mass and height. Results: Comparing body muscle mass and height 11.7 percent of participant aged 40-86 had sarcopenia. When comparing body muscle mass and weigth 33.2 percent had sarcopenia. Conclusion Determining sarcopenia among Mongolian men by comparing muscle mass and body mass resulted in 33.2 percent sarcopenia. When compared with height, 11.7 percent had sarcopenia.

Background: Class III malocclusion is considered to be one of the most difficult and complex orthodontic problems to treat. For patients whose orthodontic problems are so severe that neither growth modification nor camouflage offers solution, surgery to realign the jaws or reposition dentoalveolar segments is the only possible treatment option left. Objective: The treatment objectives were to: (1) level and align the dental arches; (2) obtain an ideal overbite and overjet, to establish correct anterior guidance; and (3) improve the facial profile. Results: Excellent facial and occlusal results were achieved with this surgical-orthodontic management, post-treatment results showed a Class I relationship and ideal overjet and overbite. The facial profile became straight type. Conclusions This case report describes the treatment of a female with dental and skeletal class III relationships. Surgical-orthodontic treatment was the best option for achieving an acceptable occlusion and a good esthetic result in this case. An experienced multidisciplinary team approach ensures a satisfactory outcome.
