Samples of Ten unit chairs were collected before using devices and after 2minutes flushing. Samples of two unit chairs were devided into pre-waterline cleaning and post waterline cleaning. Results: From ten dental unit chairs, The number of bacteria reduced by 89.9 % at highspeed handpieces, reduced by 79.2% at 3-way syringes, reduced by 7).7%at cuspidors. However, even after the water was flushed for 2minutes, the bacterial contamination level was not reduced below 100CFU/ml. From two dental unit chairs, After waterline cleaning, the number of bacteria reduced up to 100%. Conclusions: Before using devices, Flushing and cleaning of dental unit waterline reduced bacterial counts. Unit waterline cleanning is bigger effects than flushing.

Methods; 62 teeth which were lost during the duty, 278 teeth which were lost in the patients who serve over 20 years were included. Number of tooth loss by rank, location of tooth loss, reason for tooth loss, and percentage of fracture of oral and maxillofacial area was evaluated in the teeth lost during the duty. Location, period, reason of tooth loss, medical history, smoking, and additional treatment such as bone graft and sinus lift was evaluated in the teeth of the patients who serve over 20 years. Results; Most of tooth loss during the duty occurred in the soldier class, and maxillary central incisors. The reason for tooth loss was crown-root fracture(38.7%), root fracture(24.2%), crown fracture(17.7%), tooth avulsion(16.1%), and alveolar bone fracture(3.3%). Most of the tooth loss was located in the maxillary and mandibular molars in the patients who serve over 20 years. The reason for tooth loss in the patients was already lost(unknown cause, 48.4%), periodontal disease(39.4%), dental caries(7.7%), root fracture(2.8%), crown fracture(1.0%). More than half of the patients who serve over 20 years were smoker.
