Treatment of masseteric hypertrophy with botulinum toxin. A survey and a case report: Masseteric hypertrophy is a relatively uncommon condition which is characterized by unilateral or bilateral en largement of the masseter muscles. The etiology as well as the pathogenesis is unknown. However, the condition is frequently seen following clenching, bruxism, and constant gum chewing. Masseteric hypertrophy usually occurs in the second and third decades of life, and is not gender- specific. Patients with masseteric hypertrophy and cosmetic disfigurement have traditionally been managed surgically with significant morbidity. A case of an 18–year-old man with unilateral masseteric hypertrophy, treated by botulinum toxin is presented.

Water quality in Danish dental units with and without disinfection systems: Water samples from 173 Danish dental units with and without disinfection systems were evaluated for total viable bacteria (cfu/ml) and occurrence of Legionella and Pseudomonas species by cultivation and by a self contained test kit, which unfortunately did not provide reliable results. The median cfu/ml for units without disinfection was ten times higher than for units with a disinfection system. However, only half of the units with a disinfection system delivered water containing below 200 cfu/ml which is the Danish limit for supplied drinking water. Legionella species were isolated from 40 % of units without and 16 % of units with a disinfection system. By performing a thorough disinfection of units with disinfection systems and a high bacterial number the cfu/ml was reduced to acceptable levels. This investigation emphasizes the importance of regular monitoring of the water quality as well as of maintaining the disinfection systems in dental units.
