   MeSH:	TOOTH LOSS MAXILLARY DISEASES ALVEOLAR BONE LOSS + etiology JAW, EDENTULOUS
   Abstract:	Using Martin and Saller's method in analyzing 90 skulls which belonged to adults of both sexes established are twelve basic morphometric characteristics of maxillas in the recent population of Croatia. Presented are differences in the morphology of dentate and edontulous jaws. Morphometric characteristics of maxillas in the recent population of Croatia do not significantly differ from maxillar characteristics of other white ethnic groups of the same absolute age. By the change of biomechanical conditions and interaction of forces caused by the loss of teeth, reabsorption of bones occurs. The alveolar process atrophies the first, causing the reduction in the maxillar length and width in the molar, as well as in the anterior part of the bone. Although the width of the palate is constant, the reduction of its length occurs. The foramen infraorbitale approaches the alveolar margin of the bone due to the reabsorption of the alveolar ridge, but its distance from the orbital edge gets reduced too, due to the overall atrophy the bone. Advancing of age, if not accompanied with the loss of teeth, does not significantly influence morphometric characteristics of the maxilla.

   MeSH:	STREPTOCOCCUS MUTANS + drug effects CANDIDA ALBICANS ENTEROCOCCUS FAECALIS CALCIUM HYDROXIDE MICROBIAL SENSITIVITY TESTS
   Abstract:	Calcium hydroxide preparations Ca(OH)2 are used as water solutions, putly, liner, cement or artificial material. The therapeutic effect of each medicaments depends on physical and chemical characteristic of additional components. The aim of the paper is to research the sensitivity of Streptococcus faecalis and Candida albicans to different water solution concentrations of calcium hydroxide. As solid plates, Bacto-Mitis-Salivarius agar was used for S. mutans, Torlak blood agar for S. faecalis and Sabourand agar "Torlak" for C. albicans. The holes were drilled in solid plates and were filled by 0.2 ml of water solutions of Ca(OH)2. Preparations, created as described were incubated aerobically at 37 degrees C in the period of 48 hrs. Results were read after 24 as well as after 48 hrs. The examined solutions of Ca(OH)2, revealed the highest antimicrobic effect after 24 hrs. The result remained unchanged even after 48 hrs. The inhibition of S. mutans growth on the solid plate occurred with the concentration of Ca(OH)2 solution from 271.18 x 10(-2) mol/dm3 and pH 12.76. The growth of S. faecalis at the solid plate was inhibited with the concentration of 3335.21 x 10(-3) mol/dm3 and pH 12.82. The inhibition of C. albicans growth on solid plate occurred with the concentration of Ca(OH)2 solution from 1023.20 x 10(-3) mol/dm3 and pH 12.84. The difference in the sensitivity of the examined microorganisms at the same concentrations of Ca(OH)2 solution was observed.

   MeSH:	DENTITION, PRIMARY MALOCCLUSION, ANGLE CLASS II DENTAL ARCH MAXILLOFACIAL DEVELOPMENT CEPHALOMETRY
   Abstract:	The study was performed in 30 subjects with class II/1 and 30 subjects with class II/2 anomalies. The aim of the study was to assess the extent to which class II anomalies influenced individual craniometric and gnathometric dimensions as well as to determine whether there were any significant differences between the two subgroups. Craniometric dimensions were measured in each subject by means of standard measuring devices, while gnathometric analysis was carried out on plaster casts of their dental arches. Statistical processing was performed on an IBM PC-AT computer, with a SPSS/PC program support. The study results indicated the maxillomandibular and craniofacial growth to follow a specific pattern as early as in the deciduous dentition in subjects with class II anomalies. Differences between class II subgroups manifested in the range of the following parameters: all transversal craniometric dimensions were greater in class II/2, which was statistically significant in case of Eu-Eu dimension; height of the maxillary part of the face was significantly greater in class II/2; horizontal incisal step was significantly greater in class II/1; although all transversal dimensions of dental arches were considerably greater in class II/2, the differences were not statistically significant; the upper and lower dental arches were longer in class II/1 and II/2, respectively.

   MeSH:	MANDIBLE + anatomy & histology MAXILLOFACIAL DEVELOPMENT CEPHALOMETRY
   Abstract:	The mandibular angle, an important roentgenocephalometric parameter, undergoes marked changes during growth and development. The dynamics of alterations of the entire mandibular angle and its two segments was studied in a sample of 200 roentgenograms of eugnathic subjects divided into homologous age groups at 10-year scale intervals to the adult age. For each age group, three roentgenocephalometric variables were statistically processed. Results, presented numerically and graphically, led to a conclusion that the size of the mandibular angle and its superior segment decreased considerably in a defined period of time. A decrease in the values of all variables was clearly seen in both adolescence and postadolescence.

   MeSH:	DENTAL PULP CAVITY + anatomy & histology TOOTH ROOT + anatomy & histology
   Abstract:	Two hundred and sixty major apical foramina were examined stereomicroscopically to determine the contours of the apical foramen and the frequency of each shape. The observation was performed at 15 x magnification. During the examination the following shapes were observed: circle, ellipse, teardrop, number eight and irregular forms. Apical foramen most frequently had the circular shape and it was registrated in 58.8 per cent of the main root canal openings. The elliptic contour was presented in 22.7 per cent, the teardrop shape in 10.4 per cent and the shape similar to number eight occurred in 5.0 per cent of the samples. The statistical calculation revealed that the circular shape of the apical foramen is the most frequent finding (p less than 0.01). This finding seems to be optimistic in an attempt to perform the hermetic sealing of the apical foramen.

   MeSH:	MALOCCLUSION + epidemiology SOCIAL CLASS EDUCATIONAL STATUS
   Abstract:	Purpose of this investigation is verification of socio-economic status of two orthodontic groups of examinees, to find out differences and similarities between them. Out of total sample of 640 elementary school age children, 320 are orthognathous (E) and 320 disgnathous (D). The disgnathous subjects have a specific malocclusion; early tooth loss or secondary crowding. According to their sex (male, female), orthodontic condition (E, D) and age (7-14 years) children are classified into 8 groups (each consisting of 20 examinees). Socio-economic status is assessed by using data on the occupation and education level (high = V, medium = S, low = Z) of the subjects' parents. A specific questionnaire is created for the technical performance of the investigation. The results are statistically analyzed and presented in tables. The data processing is made by using UNIVAC-1110 computer in FORTRAN system language. The parents of the orthognathous (E) children are mostly of a higher and high (V) education level as compared to the parents of the disgnathous (D) children who are mostly of a lower (Z) education level. The ratio is 54.3% E to 44.6% PS. The difference is statistically significant on the level of 0.05 (x2 = 6.04, df = 2). This might indicate that a higher level of parents' education contributes to a more successful influence of parents on the environmental factors which predominantly cause orthodontic anomaly of a premature tooth loss and secondary crowding.

   MeSH:	CLEFT PALATE + pathology MAXILLA + pathology DENTAL ARCH DIAGNOSIS, COMPUTER-ASSISTED INFANT
   Abstract:	The need for a simple, routinely applicable method for morphologic analysis of maxillary arch in cleft patients resulted in development of a new original, objective and computerized method. The authors present the rationale and procedure of this method which is extremely suitable for clinical documentation, follow up and clinical investigation of cleft patients. The descriptive factors are expressed in relative numbers--rations of asymmetry and segment displacement. The relative numbers enable comparative analysis between arches of different size.

   MeSH:	DENTURE RETENTION DENTURE, COMPLETE, UPPER DENTURE DESIGN DENTAL IMPRESSION TECHNIQUE
   Abstract:	By preserving the anatomic integrity of the stomatognathic system, a prosthesis allows its physiologic activities to proceed normally. A function imprint provides a picture of the prosthesis support and relationship between mobile tissues and prosthesis rims. A high-quality function imprint required, but current literature offers different opinions and views concerning the choice and method of taking a function imprint. Several procedures covering all methodologic differences can still be singled out: taking a function imprint without pressure, taking a function imprint with pressure, taking a function imprint with the mouth open, taking a function imprint with the mouth closed. The regions with a thin and less keratinized mucosa over the bone but without a submucosal interlayer must be relieved or imprinted without pressure. Forward inclination of the head and the position of the tongue make the soft palate to acquire a functional position on taking the imprint, thus allowing the posterior pharyngeal rim of the upper prosthesis to be determined. The greater the valve effect and the lesser the space between the prosthesis base and support, the higher the negative pressure upon the support. Imbibition is achieved by the prosthesis rims lying in the initial part of mobile mucosa, and the pharyngeal rim on the border between the hard and soft palate, in the region of the "ah" line. Retention of the prosthesis is mostly secured by its posterior, dorsal patal or pharyngeal rim. When pointing to its importance in retention, it applies to the rim margins, its relation to the support and its role in the valve closure of the upper total prosthesis.

   Abstract:	Clinical picture of the fetal alcohol syndrome (FAS) is described by the example of three girls aged 9, 11 and 11 years. Besides mild to moderate mental retardation, all the three girls had a number of physical anomalies characteristic of FAS. Inheritance as the possible cause of these defects was ruled out by genetic testing. Low birth weight, delay in the postnatal growth and development, microcephaly, hypertelorism, malformed and low-positioned auricles, as well as skeletal alterations, were observed in the three girls. In two of them, epicanthus, strabismus, microphtalmia, gothic palate, crossbite and arachnodactyly were also found. Progenia, cleft palate, aplasia of the uvula, wide root of the nose, saddle nose, enamel hypoplasia, dermatoglyphic alterations, and cutaneous syndactyly and clinodactyly of the fifth finger were recorded in single cases each. One girl suffered from epilepsy. The orofacial region is especially affected in children with FAS, which necessitates specific dental care. Due to decreased intellectual abilities of such children, their treatment is particularly difficult and requires specific approach and methods of work.
