  • Lowe syndrome, also known as oculocerebrorenal syndrome, is a rare genetic disorder involving eyes, kidney, brain and musculoskeletal system, and occurs predominantly in males. The patient with Lowe syndrome is characterized with congenital cataracts, glaucoma, prominent forehead, thin and sparse hair, mental and growth retardation, muscular hypotonia, renal dysfunction, and metabolic bone disease. We have experienced a 10-year-old boy with Lowe syndrome who had poor oral hygiene and trouble for teeth brushing. To manage his behavior and systemic metabolic disorder, sedation was performed during dental care. Excessive calculus formation in this patient is caused by both medication and lack of ability to maintain oral hygiene. The dental management of those patients has to be focused on prevention due to difficulties in dental treatment and dangers of general anesthesia for the Lowe syndrome.

  • The water supplied from dental unit water systems (DUWS) in dentistry may be heavily contaminated with bacteria and thus may be a potential source of infection for both practice staff and patients. The aim of this study was to evaluate the level of heterotrophic bacteria and to confirm the presence of opportunistic pathogens from DUWS in student clinical simulation laboratory of college of dentistry. Water samples were collected from 36 ultrasonic scalers in student clinical simulation laboratory. The levels of heterotrophic bacteria in water samples were quantified by counting colony forming units (CFUs) on R2A agar media. In addition, opportunistic pathogens were detected by using the polymerase chain reaction (PCR) method. The mean CFUs were 16,095 CFU/ml for water samples and all of water samples exceeded current American Dental Association recommendations of 200 CFU/ml. Pseudomonas species and non-tuberculous Mycobacterium species were detected in the one sample and two samples, respectively, among the 36 water samples by the PCR with specific primers for these bacteria. Our study indicated that DUWS in student clinical simulation laboratory can cause potential infection in students and participants. This study suggested the dental unit water line management and wearing personal protective equipment in student clinical simulation laboratory will be needed to reduce bacterial contamination.

  • Dextranase는 dextran의 $\alpha-1,6-glycoside$ 결합을 끊는 효소로써 치석을 형성하는데 요인이 되는 dextran을 분해 제거하는 역할을 한다. 본 실험에서는 이러한 dextranase 생산 곰팡이류 중에서 Penicillium 속에 속하는 균주를 선정하여 이 효소 생산의 최적조건을 실험 검토하였다.

  • 충치와 치석의 원인인 플라그를 줄이기 위해서는 플라그의 원인인 구강내 세균을 줄이기 위해서 클로르헥시딘 제품이 나와 있고, 충치의 원인인 탈회를 줄이기 위해서는 제한급식을 하고 자기 전에 간식을 주면 안된다. 아울러 불소는 재석회화를 촉진시키므로 충치예방에 필수적이다 고양이는 충치가 없기 때문에 불소도포는 필요하지 않다.
