Background: The dental ceramic materials are constantly being developed due to their continuous clinical application in the field of esthetic dentistry. Glass ceramics (GC) materials are also of special interest for dental application due to their specific properties; and thus, they can be applied as crowns, veneers and small bridges.
Purpose: However, due to a variety of different GC materials, it is of keen interest to inspect their morphology and ion-diffusion, which also governs aging properties.
Material and methods: In this study, two different GC materials were processed, i.e., lithium silicate (LS-10) and lithium disilicate (LS-20). The aforementioned properties can be inspected by using impedance spectroscopy (IS) and scanning electron microscopy (SEM).
Results: SEM study suggested that LS-10 material is harder to mechanically process by computer-aided design/computer-aided manufacturing (CAD/CAM) technology. Furthermore, IS measurements showed that LS-20 (vs. LS-10) has more pronounced resistance properties.
Conclusion: According to IS data, it was concluded that LS-20 (vs. LS-10) has more pronounced resistance properties that point out to hindered ion-diffusion and to better aging properties.

Diagnosing child abuse still poses a challenge for healthcare professionals. We will present a case in which a physically and emotionally abused four-year-old boy had an undiagnosed lower jaw fracture for almost eight months. The child first presented with a peri-mandibular swelling and was treated with antibiotics prescribed by his doctor of dental medicine. After not having responded to antibiotic treatment, the boy was referred to the Department of Oral and Maxillofacial Surgery, accompanied by his birth mother. The deciduous mandibular molars with deep cavities were extracted since we thought that they were the reason for swelling. After several visits with his foster mother, the child was finally diagnosed with a lower jaw fracture and a psychosomatic disorder. Physical abuse by his birth parents was later on confirmed, and the consequences were insufficient growth, non-perception of pain and reduced speech development. After having been with his foster mother for almost a year, the child learned to complain when he was in pain. This report emphasizes the importance of taking a detailed medical history along with a thorough clinical examination.

Objectives: Although titanium-based implants are considered bioinert, it has been found that they are subject to corrosion and wear. This study aimed to evaluate the cytotoxic and genotoxic potential of two implant systems in gingival epithelial cells.
Material and methods: Gingival swabs were taken three times from 91 subjects. The first swab was taken before dental implant placement, the second swab 90 days after dental implant placement and the third swab 21 days following the healing abutment placement. DNA damage was analyzed using the micronucleus test. Tested dental implants with corresponding healing abutments were Ankylos and Dentium SuperLine.
Results: Of all scored forms of cytogenetic damage in gingival cells of individuals after implementation of tested dental implant systems, only an increase in the number of binucleated cells (P ≤ 0.001) was significant in contrast to control values for both tested implant systems, 90 days after dental implant placement and 21 days following the healing abutment placement.
Conclusion: It may be concluded that there are no titanium-based implant dependent cytogenetic damage in gingival epithelial cells. A slight increase in cytogenetic damage has been observed but it is of no biological relevance and might be associated with healing abutment induced effect.

Objective: The present clinical trial was conducted to evaluate the clinical performance of the biomimetic, bilayered structure utilizing a fiber reinforced bulk fill resin composite with a nanohybrid capping layer, compared to incremental packing of nanohybrid resin composite, in deep proximal cavities in permanent molars.
Material and methods: A total of 36 deep proximal cavities in vital molars were restored either with a bilayered structure of fiber reinforced composite resin as a dentine substitute and a capping layer of nanohybrid composite resin (n=18) or conventional, nanohybrid composite resin incrementation (n=18). The restorations were assessed over a period of 12 months using the modified USPHS criteria. The criteria evaluated were: fracture and retention, marginal integrity, marginal discoloration, anatomic form, proximal contact, surface texture, radiographic evaluation, postoperative sensitivity and secondary caries.
Results: There was no statistically or clinically significant difference between fiber-reinforced resin composite and conventional incremental resin composite. There was no risk for failure regarding all the evaluated modified USPHS criteria for both materials after 12 months (RR= 1(95% CI 0.0209 to 47.8503; P =1.0000)).
Conclusion: The biomimetic approach utilizing a fiber reinforced resin composite dentine substitute showed a comparable clinical performance to nanohybrid resin composite incrementation. Bulk fill fiber reinforced resin composite is an efficient alternative in restoration of deep proximal cavities in posterior teeth. Further long-term studies are necessary to confirm these results.
目的:通过临床试验,比较纳米复合树脂复合材料和纤维增强体填充复合材料在恒磨牙近端深层牙槽内的临床应用效果。材料和方法:采用双层结构的纤维增强复合树脂作为牙本质替代物和纳米复合树脂盖层(n=18)或常规的纳米复合树脂增量(n=18)修复36个重要磨牙近端深腔。使用修改后的USPHS标准对修复体进行了为期12个月的评估。评估标准为:骨折和保留、边缘完整性、边缘变色、解剖形态、近端接触、表面质地、x线片评价、术后敏感性和继发龋病。结果:纤维增强树脂复合材料与常规增量型树脂复合材料比较,差异无统计学意义和临床意义。12个月后,两种材料的所有评估修改后的USPHS标准均无失败风险(RR= 1) (95% CI 0.0209 ~ 47.8503;P = 1.0000)。结论:纤维增强树脂复合牙本质替代物与纳米复合树脂增强牙本质替代物具有相当的临床性能。纤维增强树脂复合材料是一种有效的修复后牙近端深腔的材料。需要进一步的长期研究来证实这些结果。

Introduction: Orthopantomography is amongst the most commonly used dental imaging modalities. Calcifications in the projection of carotids on orthopantomographs are found in 3-15% of general population and commonly represent calcified atherosclerotic plaques. Carotid atherosclerotic changes are one of the most frequent causes of stroke, which is the second most common cause of death and the leading cause of disability globally. Our aim was to determine the relationship between calcifications in the projection of carotids on orthopantomographs, carotid stenosis and stroke, and the correlation between stroke risk factors, calcifications on orthopantomographs and the degree of carotid stenosis.
Materials and methods: Doppler ultrasound and brain MRI were performed in 41 patients with unilateral or bilateral calcifications on orthopantomographs. Anamnestic data relevant to stroke risk were gathered.
Results: Significant stenosis >50% was found in almost 15% of our patients. There was a significant correlation between hypertension and carotid calcifications. No statistically significant correlation between calcifications and significant stenosis was found. Patients with previous stroke were approximiately 5 years older than those without stroke.
Conclusion: Preliminary results show no statistically significant correlation between calcifications on orthopantomography and significant carotid stenosis, but further investigation is needed.

Introduction: The literature reviewed in this paper suggests that infertile patients present worse periodontal status, which may be causative to conception complications. This study aimed to validate an aMMP-8 point-of-care mouth rinse test in the population of women with unexplained infertility and compare it to age-matched fertile women with and without periodontitis. Furthermore, blood sampled inflammatory parameters were analyzed and compared between the two groups. It was hypothesized that the infertile women would present worse periodontal status and a greater number of positive aMMP-8 tests than fertile women, and they would have increased inflammatory blood parameters.
Material and methods: The study included 50 healthy norm-ovulatory females aged 25-45 years with strictly defined unexplained (idiopathic) infertility, and 50 healthy norm-ovulatory women of the same age who had conceived and delivered naturally.
Results: The sensitivity and specificity of the test for detecting periodontitis was 84% and 72% in the group of infertile patients, 88% and 68% in the group of fertile patients and 86% and 70% in the overall patient population. Infertile patients with periodontitis had less advanced periodontitis than the control group although this difference was not statistically significant. Blood inflammatory markers were significantly higher in infertile than in fertile women.
Conclusion: This study has shown that infertile patients had better periodontal status and less advanced periodontitis than fertile women of the same age. Therefore, when interpreting the results of aMMP-8 tests for diagnosis of periodontitis, one should keep in mind the periodontal status of the examined population.

Objective of work: It is unclear how long patients need to adapt to new dentures. This study assessed adaptation and five years of clinical use, comparing complete denture wearers (CDs) and mini-implant mandibular overdenture wearers opposing a maxillary CD (MDI-OD), based on oral health reported quality of life (OHRQoL) and orofacial esthetics (OES).
Material and methods: A total of 36 subjects in the CD group (25 females) and 30 subjects in the MDI group (20 females) completed the 5-year study. All patients received new CDs, but in the MDI-OD group, four mini-implants were inserted interforaminally in the mandible before denture manufacture. Participants filled in the OHIP-EDENT and OES questionnaires one day after dentures' delivery, on the 3rd, 8th, 15th, 30th day, and at the 1-, 3- and 5-year follow-up examinations. Statistical analysis comprised descriptive methods, X2 test, independent t-test, Friedman, and Mann-Whitney test.
Results and conclusions: Both groups' adaptation to new dentures was completed within a month. The MDI-OD group had significantly better OHRQoL in all follow-ups except for the 3rd and 8th day, probably due to soreness and pain, the reason why the MDI-OD group had limitation in functioning in the first days after new dentures' delivery. Already after the third year and at the fifth year, OHRQoL worsened (p<0.01) in both groups. However it was significantly more pronounced in the conventional CD wearers (p<0.01) than in the MDI-OD group. Orofacial esthetics was highly scored in both groups. The scores dropped down only after three years, equally in both groups.

Objective: The purpose of this in vitro study was to evaluate the effects of four over-the-counter (OTC) whitening products on the microhardness, surface roughness, color, shear bond strength (SBS) and surface charecteristics of human enamel compared with a product used for dentist-supervised home whitening.
Materials and methods: Seventy eight enamel specimens allocated into 6 groups (n=13): 1-Opalescence PF 10% (OP) dentist prescribed home whitening product, 2-Opalescence Go prefilled tray (PT), 3-Opalescence Whitening Toothpaste (WT), 4-Listerine Healthy White whitening mouth rinse (WMR), 5-Cavex Bite&White whitening pen (WP) and 6- no treatment (Con). The microhardness (VHN), surface roughness (Ra) and color of the specimens were measured (T0). The specimens were then subjected to whitening protocols for 14 days (T1.) followed by artificial saliva storage for 14 days (T2). The measurements were repeated at T1 and T2. The SBS test was done after the application of 35% phosphoric acid (Scotchbond Universal Etchant), followed by a universal adhesive (G-Premio Bond) and a micro hybrid/universal resin composite (Essentia) into a Teflon tube attached to the enamel surface (p<0.05). Surface morphologies of the enamel surfaces were examined by SEM. p value was set at 0.05.
Results: Application of OP, PT and WP decrased the microhardness of enamel specimens (p<0.05) whereas, no significant changes were seen in the microhardness of enamel specimens treated with WT and WMR (p>0.05). Ra values of enamel specimens increased with the application of OP, PT and WT (p<0.05); whereas no changes were observed after the applications of WMR and WP (p>0.05). OP, PT, WMR, and WP changed the color of the enamel(p<0.05). There were not any significant differences among the SBSs groups, apart from OP applied enamel specimens. OP showed the least SBS values (p=0.001). SEM observations revealed smooth enamel surfaces.
Conclusions: The whitening products affected the microhardness, surface roughness, color of enamel differently. Only OP decreased the SBS of the enamel.

Objective: To evaluate the perceptions of altered incisor gingival position among dental specialists, dentists, dental students, and laypeople.
Materials and methods: Four digital smile photographs with altered gingival margin position of the right maxillary incisor (0, 1, 2, and 3 mm) were presented to a sample of 232 respondents (71.1% female; 28.9% male): 42 dental specialists, 63 dentists, 33 dental students (1st to 3rd year), 38 dental students (4th to 6th year) and 56 laypeople. The questionnaire consisted of four randomly displayed photographs, administered via Google Form, and respondents were asked to rate the images on a scale from 1 to 5, from the least attractive to the most attractive. A statistical analysis was performed using the TIBCO Statistica program (v. 13.3. 0, TIBCO Software Inc., Palo Alto, CA, USA; 2017). According to the Shapiro- Wilk's test, the data were not distributed normally. The Kruskal-Wallis test with post hoc multiple comparisons with the Bonferroni adjustment were used to compare group esthetic scores and to determine the threshold levels of deviation at which each group was discriminated between esthetic and non-esthetic situations.
Results: Median values of esthetic scores decreased in all groups as the gingival asymmetries increased. Dental professionals were significantly more critical of esthetics than laypeople in all levels of asymmetry. The greatest difference was found for 2 mm of gingival asymmetry (p=0.002).
Conclusion: From the results of our study, we can conclude that the perception of gingival asymmetries in the esthetic zone of smile differs among dental specialists, doctors, students, and laypeople. Dental specialists, doctors, and clinical students were more critical of these asymmetries, while preclinical students and laypeople noticed only 2 mm or more of gingival asymmetry of central incisors.

Objectives: To determine the differences between pediatric patients with eating disorders (ED) and the control group in the amount of saliva and the concentration of total amylase and electrolytes in saliva, and to evaluate the correlation between the saliva changes and nutritional status.
Material and methods: The study included 101 participants (14.34 ±1.99 years), out of which 50 participants with ED subgroups and 51 participants in the control group. Data were statistically analyzed (Mann-Whitney, Kruskal-Wallis, chi-square, Spearman rank correlation test, α=0.05).
Results: No significant differences in salivary volume between the groups were found. A significant difference in the volume of saliva secreted in the 5th and 15th minute was found between the anorexia nervosa and bulimia nervosa subgroups. The examined anthropometric parameters were marginally or significantly positively associated with saliva volume at 5 and 15 minutes, noting a more significant correlation of the same at 15 than at 5 minutes. The patients with ED had a significantly higher concentration of inorganic phosphates in saliva while the concentrations of other electrolytes and total amylase in saliva did not differ significantly.
Conclusions: Nutritional status affects salivation. There is a difference in saliva volume in pediatric patients with different ED disorders. Variations in saliva electrolytes in pediatric patients with ED are possible.
