"Telah dilakukan penelitian untuk mengetahui waktu optimum pemajanan sinar ultraviolet (UV) yang menyebabkan mutasi pada bakteri penghasil vitamin BU Pseudomonas denitrificans BIOMCC B12 F942/288. Pemajanan sinar UV untuk perlakuan mutasi menggunakan illuminator UV pada panjang gelombang 254 nm dengan intensitas sebesar 590 uW/cm2. Waktu pemajanan optimum untuk perlakuan mutasi dengan sinar UV adalah yang menyebabkan rasio kematian 90?95%. Pengambilan data mutasi dengan variasi waktu pemajanan selama 30, 60, 90, dan 120 detik. Waktu pemajanan sinar UV yang menghasilkan rasio kematian 90-95% adalah 90 detik.

Optimal time in ultraviolet illumination as mutagen for bacteria vitamin BU producer Pseudomonas denitrificans Schlegel BioMCC BI2 F942/288 had been researched. Ultraviolet was illuminated at wavelength 254 nm with intensity 590 uW/cm2. Optimal time of illumination will make 90?95% death rate. Illumination was done in several variation time (30,60,90, and 120 second). Optimal time for make 90?95% death rate of bacteria vitamin 812 producer Pseudomonas denitrificans Schlegel BioMCC B!2 F942/288 is 90 second."

"In adult patients if the jaw discrepancy is too great to compensate for, and camouflage by tooth movement alone, surgery is the only way to obtain a resonable result. Before surgery, the orthodontist must establish not only anteropostrior and transverse position, but also the vertical position of the teeth. Inadequate orthodontic preparation can jeopardize the quality of the surgical result. Occlusion is important but satisfactory facial esthetic must accompany it. A good team work between orthodontist and oral surgeon is the key of succes of the treatment, which will be shown in case reports of 3 patients."

"Le Fort I osteotomy is the surgery in the maksila similar to the live fracture of the Fort I. In the orthognathic surgery, Le Fort I osteotomy is the best choice for the correction of vertical dimension and relatively easy and middle and sufficient to reposisi and maksila. For the open bite case anteriory and postering in the patient could be performed. Le Fort I osteotomy in the posterior and repositioned part of maksila toward posuride so it could be occluded, functional and restored in the intended aesthetic."

"A young girl 20 years old with mandibular prognatism has been treated with orthodontics and surgical treatment in between. Mandibular set back was done intra orally 5mm length with bilateral sagital split ramus osteotomy method. And rigid fixation was done by inserting three 2mm bicortical screws for stabilizing the fragment. This method allowed the bony segments to heal properly and allowed the patients to function sooner."
