   Abstract:	The study was carried out in two age-matched groups of patients from two different periods of time. The aim of the study was to determine whether any craniofacial system alterations attributable to the influence of secular trend had occurred during a defined period of time. Four basic craniofacial variables, from which the craniofacial indices were derived, were measured. The findings were statistically processed by the basic parameter evaluation and testing of differences of arithmetical means of the same variables between the two study groups. The results showed the following alterations to have occurred during a 13-year period due to the secular trend effects: cranial indices decreased, mostly by a significant cranial length increase (g-op); and facial indices decreased, mostly by a facial height decrease (n-gn).

   Abstract:	Saliva is an important factor upon which general health of the oral cavity is dependent and which influences the occurrence of caries. In diabetic patients, xerostomia may occur due to pronounced polyuria in non-regulated and inadequately regulated cases. The aim of this study was to determine the amount of stimulated saliva and salivary pH in diabetic patients and in normal subjects, and to study the possible difference in the occurrence of caries. Results pointed to a significant decrease in the amount of stimulated saliva in insulin dependent diabetics (1.22 ml/min vs. 1.43 ml/min in normal subjects; p less than 0.01). The lowest amount of stimulated saliva was found in non-regulated diabetics (1.00 ml/min). In all diabetic patients, a significantly lower salivary pH was recorded as compared to normal subjects (p less than 0.01). The DMFS index was significantly higher in both insulin dependent and non-insulin dependent diabetics as compared to normal subjects (p less than 0.01). Concerning the state of diabetes control, significant differences at the level of p less than 0.01 in the DMFS index were observed among all groups of subjects (normal subjects, and regulated, inadequately regulated and non-regulated diabetics). A decreased salivary flow and pH may represent one from a series of caries risk factors in diabetics, especially in inadequately regulated and non-regulated cases of the disease.

   Abstract:	Prevalence of anomalies of deciduous teeth has been analyzed in the general population of Zagreb preschool children. The sample comprised 2,987 children from 3 to 6 years of age (1,582 boys and 1,405 girls). Hypodontia was found in 0.47%, hyperdontia in 0.10%, and double teeth in 0.43% of total sample. Total prevalence of all anomalies in the sample was 1.0%. The sample for the analysis of permanent dentition has been enlarged with the clinical sample of children having the same anomalies and comprised 48 children. In all children with anomalies of primary teeth the orthopantomograms were taken and the status of permanent dentition was analyzed. In children with hypodontia in primary dentition hypodontia of permanent teeth was found in 100% of cases. Patients with hyperdontia of primary teeth displayed anomalies in permanent dentition in 85.7%, while in children with primary double teeth, anomalies of permanent teeth were present in 61.1% of cases. Missing deciduous teeth were found in both jaws in only 8.7% of cases, and in 34.8% in permanent dentition. Symmetrical occurrence of hypodontia of primary teeth (i.e. in both sides of jaws) was significantly higher in boys (56.3%) than in girls (28.6%). In permanent dentition symmetrical occurrence of hypodontia was significantly higher than in primary dentition (81.3% in boys and 57.1% in girls). The most frequently missing primary teeth were maxillary lateral incisors (48.8%) followed by mandibular central incisors (34.9%). Hyperdontia of primary teeth has been found only in boys, and it related only to the maxillary lateral incisors. Anomalies of deciduous teeth show a high degree of association with the finding in the permanent dentition.(ABSTRACT TRUNCATED AT 250 WORDS)

   Abstract:	Laser effect on enamel is manifested as consequence of temperature changes. Enamel melts, vaporises and a crater, and fissures are formed. Retention surface for anchoring of composite resin was obtained in intact approximal surfaces of premolars with CO2 laser (0.5, 1 and 3 W, sport size 1 and 1.5 mm, 0.2 and 0.5 s). The study results reveal composite and lased enamel interfaces are stronger then composite and inlased enamel (p less than 0.01) but weaker than composite and acid pretreated enamel interface (p less than 0.01).

   Abstract:	In this study, teleroentgenocephalograms of 34 subjects with at least 20 natural teeth were used. Correlation between the angle formed by linking the PORION-NASION-SPINA NASALIS ANTERIOR (PONANS angle) points and the angle made by Frankfort horizontal and occlusion plane was studied. The coefficient of correlation was 0.1263. It is considered that there is no correlation if the coefficient of correlation is less than 0.5. Thus, there was no correlation in the study sample, which is consistent with the results reported by Karkazis and Polyzois, but in disagreement with those published by Monteith. In our sample, the occlusion plane could not be oriented in the articulatory space or in toothless mouth by means of the method proposed by Monteith.

   MeSH:	MANDIBULAR NEOPLASMS + diagnosis + pathology ODONTOGENIC TUMORS NEOPLASM RECURRENCE, LOCAL
   Abstract:	Central odontogenic fibroma of the jaw is not a clearly defined lesion. It is rare, asymptomatic, usually found in the mandible and equally involving both sexes. The characteristic feature of the lesion is a high histomorphologic variability, while clinical, x-ray and histologic behavior of the tumor is not specific. All this contributes to the difficulty in diagnosis. Conservative enucleation of the benign tumor is the treatment of choice. The recurrence is rare, but, those with more epithelial elements are more prone to recur.

   Abstract:	Cervical lesions and their proper treatment still represent a considerable professional problem. The incidence of these lesions increases with aging of the population. The lesions have to be treated because of esthetic reasons, hypersensitivity to stimuli, and possible further loss of dental substance. Most of the restorative materials used to date have failed to fulfill both functional and esthetic requirements. In this study, a novel approach to the treatment of these lesions using type II glass ionomer cement, with an additional possibility of the application of the final composite layer to attain the maximal esthetic effect, was investigated. This filling was found to have great advantages over both classical fillings and the composite materials alone, because it chemically binds to dentin, exerts a marked caries-protective effect through a continuous release of fluor ions, and provides the best esthetic effect in combination with composite materials (when necessary).

   MeSH:	MOUTH DISEASES + diagnosis MOUTH NEOPLASMS DIAGNOSIS, ORAL + methods
   Abstract:	Only a successful cooperation of an oral surgeon and the pathologist can ensure a reliable diagnosis. The authors have analyzed operations performed during 1990 at outpatient clinic of the Department of Oral and Maxillofacial Surgery, University of Zagreb, School of Dentistry. Clinical appearance of the disease and clinical diagnosis sometimes enable us to recognize the real nature of the disease. The clinical diagnosis in correlation with the histological diagnosis can be either denied or improved. The aim of this investigation was to correlate the clinical and the histological diagnosis and to find out the number of improvement. Material most often sent for histological examination was an operated cyst. Although the removed tissues were analyzed under different clinical diagnoses, approximately 70% of the clinical diagnoses corresponded to the histopathological findings. In one case the clinical diagnosis of benign lesion--hyperkeratosis-- was after histopathological examination find as carcinoma planocellulare. The authors recommend every part of the excised tissue to be sent for a histopathological examination.

   Abstract:	An 18-year female patient with dysostosis cleidocranialis, treated for dental anomalies characteristic of her basic disease since the age of 12, is described. Delayed resorption of deciduous teeth and eruption of permanent teeth were recorded. At the age of 12, the patient had still had all deciduous teeth, with the exception of lower incisors and right upper mesial incisor. The presence of 11 succedaneous teeth, 7 in the maxilla and 4 in the mandible, had been recorded by X-ray. The treatment performed step by step is presented. Firstly, deciduous teeth were extracted, and a prosthesis for both the maxilla and mandible were constructed to stimulate eruption of permanent teeth. All supernumerary teeth from the jaws were also surgically removed. After the permanent tooth eruption had been accomplished, orthodontic treatment of these teeth was required and it has still been successfully performed. Thus, a conclusion is made that the treatment of dental anomalies should start at the time of normally expected deciduous tooth exfoliation.
