ABSTRACT
In order to show the effectiveness of preoperative antiseptic mouthwash the authors undertook a prospective study in 120 patients who underwent elective surgery under general or local anesthesia. Patients were allocated toone of 4 groups, depending on whether the oral cavity was washed preoperatively with 1% cetrimide, chlorhexidine, povidon-iodine or sterilized normal saline solution (control group). Aerobic and anaerobic bacterial samples were taken from the inferior vestibulum mucosa before surgery, 5 min after the start of the operation and at the end of the procedure. The results show a statistically significant reduction in bacterial counts during procedures in which antiseptics are used to wash the oral cavity preoperatively. 1% cetrimide solution was the most successful in reducing intra-oral bacterial counts and produced the longest lasting antiseptic effect. Chlorhexidine is a good option for procedures longer than 1 hour, while povidon-iodine is recommended for procedures lasting up to 1 hour. Normal saline reduced bacterial counts in the specimen taken 5 min after washing but this short-lasting effect is due to mechanical cleansing rather than the antiseptic effect.

The aim of this retrospective study was to report frequency of sporadic odontogenic keratocysts (sOKC) according to the age and gender, as well as location (mandible, maxilla, soft tissues, and maxillary sinus). Four hundred and twenty nine sOKC confirmed pathohistologically in a period from 1965-1998 were included in this study. The average age of patients with sOKC was 43.11 (age range 10-91), in males 42.06 and in females 44.72 years. More frequently sOKC were found in males (60.61%) in comparison to the females (39.39%). Therefore, ratio between males and females was 1.5:1. Diagnosis of sOKC is usually established in patients aged 21-30 (18.88%), in males usually aged between 21-30 (23.46%), and in females aged between 11-20 (18.93%). sOKC are more frequent in males according to the age groups, except between age 61-70 where sOKC were more frequent in females. Most frequently, sOKC occurred in the mandible 70.16%, 12.35% of sOKC were found in the maxilla, 12.82% in soft tissues and 4.66% in the maxillary sinuses.

The aim of this study was to evaluate the mean radiographic length of styloid process in a sample of Croatian population, and based on biological basis, to suggest a classification applicable in clinical practice. Two hundred and ninety six panoramic x-rays were examined, out of which 161 from males and 135 from females. The length of the styloid process was measured and age analysis was conducted. The styloid process was observed in approximately three-quarters of the studied sample. The mean length of the styloid process was 21.6 mm for the right side and 21.2 mm for the left side. Statistical analysis of the obtained data shows the existence of three different groups of styloid processes: short (under 21 mm), normal (21-30 mm) and elongated (more than 30 mm) styloid processes. This study explains trimodal distribution as a consequence of developmental changes. This classification is both the biologically based and clinical relevant.
