Opis: Obraz in zobje so v psihosocialnem smislu najpomembnejši del človeškega telesa. Raziskava je imela dva glavna cilja: prvič, ugotoviti povprečno dolžino in širino obraza ter dolžino in širino klinične krone zgornjih centralnih sekalcev v tej demografski skupini; in drugič, analizirati razmerje med obraznim indeksom in zobnim indeksom. S prepoznavanjem vzorcev in korelacij smo želeli prispevati k bolj individualnim in učinkovitim restavrativnim, protetičnim in ortodontskim zobozdravstvenim obravnavam.

Opis: Objectives:This study was done to determine the timing of eruption of permanentteeth by sex and the number of permanent teeth erupted at different ages and toassess its association with malocclusion. Material and Methods:The sample for this study consisted of 633 healthy subjects(317 boys and 316 girls) aged between 5.0 and 15.0 years. The subjects were dividedinto subgroups considering an age interval of 1 year. Results:The mean eruption times were lower for girls compared with boys exceptfor the maxillary and mandibular second premolars and second molars, which werefound to erupt earlier in boys. All the permanent mandibular teeth, except thesecond premolars, tended to erupt earlier than their maxillary antagonists in bothsexes. The sequence of eruption differs between girls and boys in the maxillarycanine and maxillary second premolars. In Class III malocclusion, all the permanentmandibular teeth erupt earlier than their maxillary antagonists. In the entire sample,the correlation between the number of erupted teeth and age was strong (p< .05),but the differences between sexes were not significant. Conclusions:It is important to know the normal eruption time of permanent teeth inthe population due to diagnosis and better treatment planning in pediatric dentistryand orthodontics.

Opis: Digitalization and additive manufacturing offer new possibilities in the manufacturing of individualized medical and dental products. In the paper we present the results of the first 30 consecutive growing patients (15 males and 15 females), with a mean age of 13.69 years (SD = 1.26), who were treated for mandibular retrognathia (skeletal Class II malocclusion), using fixed sagittal guidance (FSG) appliance, individually manufactured by selective laser melting (SLM). Lateral cephalometric radiographs were taken before (T0) and after (T1) treatment and a detailed cephalometric analysis was performed. with a special focus on a time period for malocclusion correction. The analyzed data were compared with the control group (CG; treated with intermaxillary Class II elastics) that was matched for pretreatment age and pretreatment cephalometric measurements. Both methods were effective in the correction of Class II malocclusion, but the time period of correction was significantly shorter (16.03 ± 1.09 months vs. 20.65 ± 4.12 months) with the FSG appliance. After treatment visual skeletal and dentoalveolar effects were achieved, with statistically significant differences measured in mandibular incisors inclination (0.45° in FSG and 2.84° in CG) and distance (−0.61 mm in FSG and 0.13 mm in CG), in mandibular first molar inclination (−1.07° in FSG and 1.18° in CG) and overbite (−3.82 mm in FSG and −2.46 mm in CG), all in favor of FSG appliance. After the final mean treatment time of 16.03 ± 1.09 months, visual skeletal and dentoalveolar effects were achieved, with significant differences in sagittal (SNB angle, SNPg angle, mandibular length (CoGn) and consequently decrease in ANB angle) as well as in vertical (lower anterior facial height (LAFH) and gonial angle) measurements noted, with no reported complications. As the time needed for malocclusion correction was comparable with the reports in the traditional use of the functional appliance and as all the cosmetical and functional changes in all the treated patients remained stable after a 2-year observational period, growing patients with Class II malocclusion could benefit with this type of treatment. As all the cosmetical and functional changes in all the treated patients remained stable after a 2-year observational period, growing patients with Class II malocclusion could benefit from the treatment with FSG appliance.

Opis: Objective: To analyze the possible association between hypodontia and epithelial ovarian cancer (EOC), with the special interest in hypodontia pattern. Materials and Methods: One hundred twenty women with EOC treated at the Department of Gynecologic and Breast Oncology at the University Clinical Centre and 120 gynecologically healthy women of the same average age were reviewed for the presence and pattern of hypodontia. Collected data were analyzed for frequency, tooth type, location per jaw and side, number of missing teeth per person, and family history of hypodontia. Results: The results of the study showed prevalence of hypodontia in 19.2% of women with EOC and in 6.7% of women in the control group (P = .004). The most frequently missing teeth for women with EOC and women in the control group were maxillary second premolars and maxillary lateral incisors, respectively. Unilateral occurrence of hypodontia was more common than bilateral occurrence in women with EOC (P = .034). Of women with EOC and hypodontia, 21.7% reported a positive family history of hypodontia compared with no report in the control group of women with hypodontia (P = .150). Conclusions: The results statistically support possible association between EOC and hypodontia. Because hypdontia can be recognized early in life, this finding could possibly help in earlier detection of EOC, resulting in better prognosis and treatment in earlier stages of the disease. Earlier EOC diagnosis and treatment could save many lives.
