   Abstract:	Radiographic assessment of “bone quantity“ is of great value in planning dental treatment and it also has its applications in orthodontics.The aim of this study was to assess the cortical thickness of the lower border of the mandible using linear radiomorphometric indices, and to determine if it is correlated with different age, gender and malocclusion categories in orthodontic pretreatment period of the patients.Seventy seven patients - 30 boys (42.8%) and 47 girls (57.2%), participated in the study.The results of the statistical analysis revealed no signifi cant difference between the right and the left side measurements for mental and antegonial indices (p>0.05). The right gonial index was signifi cantly higher than the left (p<0.05). All linear radiomorphometric indices increased with age. The cortical thickness at the angle of the mandible demonstrated the highest value in Class III malocclusion group (p<0.01). Based on the results of this study, assessment of linear radiomorphometric indices could be clinically valuable for the evaluation of the growth and development of the mandible and for assessing results of orthodontic treatment.

   MeSH:	BONE AND BONES DENTURE + adverse effects
   Abstract:	Success of prosthodontic treatment depends on the state of bone tissue in the jaws and requires a certain amount of bone under the denture to provide stability in function. The aim of the study was to determine whether the bone mineral density (BMD) of the mandible and some linear radiomorphometric indices measured on panoramic radiographs are correlated with different removable denture wearing. 136 removable denture wearers (72 complete removable denture wearers, 64 partial removable denture wearers) participated in this study. All the patients were screened using panoramic radiographs standardized with copper stepwedge. BMD measurements were expressed in equivalents of the actual stepwedge thicknesses. Linear radiomorphometric indices were measured on each panoramic radiograph. Results revealed statistically significant differences in measured indices between complete and removable partial denture wearers (p < 0.05). Statistically significant differences in measured BMD values between different type of the dentures worn were found under the denture bases on the superior border of the mandible (p < 0.05). It seems that the different types of denture loading influences BMD changes as well as the thickness of cortical parts of the mandible.

   Title in English:	Mandibular Bone Mineral Density Changes Dependent on the Denture Support. A Six Month Follow up Study
   Title in Croatian:	nema
   Type of Article:	congress abstract
   MeSH:	BONE AND BONES DENTURE + adverse effects
   Abstract:	Reduction in the height of the alveolar edentulous ridge in denture wearers is a well documented problem which depends on various local and systemic factors. Changes of bone mineral density (BMD) in denture wearers have not yet been documented in follow-up studies. The aim of this study was to determine the changes in BMD of the mandible in complete (CD) and removable free-end saddle denture wearers (RPD) during a six month period (both groups had complete dentures in the maxilla). Twenty RPD patients (5 male, 15 female) and 20 CD wearers (7 male, 13 female) participated. The BMD measurements were performed on digitised dental panoramicradiographs (DPR) with a 5 step copper stepwedge attached to each film cassette. Grey levels of each step of the stepwedge were transformed to optical density values and using the 3rd degree polynomial the regression formula was calculated for each digitised image to express BMD values of the measured region of interest (ROI) in the copper stepwedge thickness equivalents.The results revealed that the BMD values of the examined ROIs under the distal end of the CD decreased, and in contrast, the matching BMD values under the distal end of the RPD increased, during the six month period, although the changes did not reach a statistically significant level (p>0.05). The BMD values on gonion increased significantly in both examined groups (p<0.05), whichwas attributed to the increased load of the strain forces of the masseter muscle at gonion after the denture delivery.

   MeSH:	DENTURE, PARTIAL, REMOVABLE BONE AND BONES
   Abstract:	Residual ridge resorption is a result of the influence of many differentlocal and systemic factors (patient’s age, traumatic damage, differentpathological conditions, mineral metabolism disorders, osteoporosis,hyperparathyroidism and hormone disbalance).Some parts of the skeleton react differently to the mentioned factors.The resorptive changes are not always the same intensity in all theparts of the skeleton.There are many different results in the investigation of the relationship between maxillary and mandibular resorption and the resorption of the rest of the skeleton.Alveolar ridge resorption is correlated with removable denture wearing. The resorption of the edentulous alveolar ridge is more extensive in full or partial denture wearers with mucosa- or mucosa-gingival support than in partial denture wearers with gingiva-mucosal support.One of the easiest methods for early diagnosis of bone structure changes in the upper and lower jaws is clinical microdensitometry,using a standardised intraoral or panoramic radiograph.

   MeSH:	DENSITOMETRY BONE AND BONES RADIOGRAPHY, PANORAMIC
   Abstract:	The precision of the method of microdensitometry on panoramic radiographs (PR), using a five step copper stepwedge, was examined. Two PRs, one after the other, were made for each of the six examined patients. All the PRs were digitised. Gray levels were measured on the stepwedge and on the region of the interest. Measured gray level values were expressed in equivalents of the stepwedge thickness using 3rd degree polynomial. Comparing the values of the equivalents in the region of interest on the first and the second digitised image of the same patient, the differences were within 10%. The results revealed that the method detects mineral bone changes, which surpass more than 10% of the density on PR.

   MeSH:	DENSITOMETRY BONE AND BONES RADIOGRAPHY, DENTAL
   Abstract:	The precision of a method of microdensitometry on digitized images, using six step copper stepwedge (SW), was studied. Two retroalveolar radiographs were made for each of the six examined patients. Lynotype-Hell (8-bit, 300DPI) transparent scanner was used to scan the radiographs. All the images were, prior to the measurements, inverted. The digitized radiographs were saved in the Issa-program for archiving radiographs, while the optical density (OD) was measured by using software Scion image for 6 steps of the SW and 7 regions of interest (ROI). The gray levels (GLs) were converted into the ODs for both images by formula OD = -log Ii /255, where Ii = measured intensity. ODs of each step of the SW were correlated with the copper thickness of the related step and the regression formula was thus derived from the relationship of the OD and the actual thickness of the related step through the third degree polynomial function. The results revealed that the method detects mineral bone changes, i.e. OD changes, which surpass more than 7% of density on the images.
