Summary Introduction Direct pulp capping is an important therapeutic method that has goal to provide formation of dentin bridge and healing process of the pulp. The aim of this study was to investigate the effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite on exposed dental pulp in Vietnamese pigs. Material and Methods The study was conducted on 30 teeth of two Vietnamese pigs (Sus scrofa verus). On buccal surfaces of incisors, canines and first premolars, class V cavities were prepared with a small round bur and pulp horn was exposed. In the first experimental group (10 teeth) the perforation was covered with new nanostructural material based on calcium silicate systems (CS). In the second experimental group, the perforation was covered with compound of calcium silicate systems and hydroxyapatite (HA-CS) (10 teeth). In the control group, exposed pulp was covered with Pro Root MTA® (Dentsply Tulsa Dental, Johnson City, TN, USA) (10 teeth). All cavities were restored with glass ionomer cement (GC Fuji VIII, GC Corporation, Tokyo, Japan). Observation period was 28 days. After sacrificing the animals, histological preparations were done to analyze the presence of dentin bridge, inflammatory reaction of the pulp, pulp tissue reorganization and the presence of bacteria. Results Dentin bridge was observed in all teeth (experimental and control groups). Inflammation of the pulp was mild to moderate in all groups. Neoangiogenesis and many odontoblast like cells responsible for dentin bridge formation were detected. Necrosis was not observed in any case, neither the presence of Gram-positive bacteria in the pulp. Conclusion Histological analysis indicated favorable therapeutic effects of new nanostructural materials based on calcium silicate systems and hydroxyapatite for direct pulp capping in teeth of Vietnamese pigs.
直接盖髓是一种重要的治疗方法，其目的是提供牙本质桥的形成和牙髓的愈合过程。本研究的目的是研究基于硅酸钙体系和羟基磷灰石的新型纳米结构材料对越南猪暴露牙髓的影响。材料与方法对2头越南猪(Sus scrofa verus)的30颗牙齿进行研究。在门牙、犬齿和第一前磨牙颊面，用小圆牙柄制备V类牙槽，露出牙髓角。在第一组(10颗牙齿)中，穿孔处覆盖了基于硅酸钙系统(CS)的新型纳米结构材料。第二组用硅酸钙体系和羟基磷灰石复合材料(HA-CS)覆盖龋孔(10颗牙)。对照组使用Pro Root MTA®(Dentsply Tulsa Dental, Johnson City, TN, USA)覆盖外露牙髓(10颗牙)。所有空腔均采用玻璃离子水门合剂(GC Fuji VIII, GC Corporation, Tokyo, Japan)修复。观察期28 d。牺牲动物后进行组织学准备，分析牙本质桥的存在、牙髓的炎症反应、牙髓组织重组和细菌的存在。结果实验组和对照组均可见牙本质桥。各组牙髓炎症均为轻至中度。新血管生成和许多成牙本质样细胞负责牙本质桥的形成。在任何情况下均未观察到坏死，也没有在牙髓中发现革兰氏阳性细菌。结论基于硅酸钙体系和羟基磷灰石的新型纳米结构材料对越南猪牙齿直接盖髓有良好的治疗效果。

Summary Introduction The aim was to evaluate the difference in en-face anthropometric facial parameters and proportions of patients with Class II malocclusion, before and after orthodontic treatment as well as changes in linear parameters and facial proportions and their deviation from ideal values. Material and method In this study, en-face photographs before and after the treatment of 50 Class II malocclusion patients were used. Patients were divided in two groups; first group comprised 25 patients treated with multibracket appliance with extractions, and second group included 25 patients treated without extractions, using fixed functional Herbst and multibracket appliance. On each and every photo before and after the treatment facial points and lines were drawn, and linear parameters were determined, based on those markers. Results showed change in anthropometric parameters in both groups of patients. Statistically significant difference was found for parameters in the middle and lower facial third. Facial proportions changed after the treatment in both groups and they approached ideal values and golden proportion 1:1.618 in the lower facial third. Conclusion Patients with Class II, division 1 malocclusion, deviate from an ideal set of proportions, particularly in the lower facial third. After the orthodontic treatment, anthropometric parameters in the lower facial third were approaching ideal values.

Summary Introduction Obturation as the final phase of endodontic treatment aims to provide complete hermetic filling along the entire length of the canal system from the coronal opening to the apical end. The aim of this study was to evaluate histological response of bone tissue on the implantaton of zinc oxide based material in artificially prepared defect in the mandible of rats. Material and method For the experiment, sixteen male Wistar rats were used. Using sterile steel burs a defect was made in mandible, between the midline and mental foramen. Zinc oxide based sealer was implanted in the defects of experimental group while the defects of control group healed spontaneously. One half of animals in both groups were sacrificed after thirty days, and the second half after ninety days. Microscopic preparations consisted of the defect with surrounding bone and after processing were analysed using light microscopy. Results The thirtieth day after implantation of the material, fibrovascular connective tissue was noted, with scant chronic inflammatory cell infiltrate. Away from the experimentally made defect, in the depth of the bone, lamellar bone with well-formed larger osteons was noted as well as enlarged Volkmann and Haversian canals. Ninety days after implantation of the material, there was no restitutio ad integrum, but intense focal remodelling of bone tissue was noted. Conclusion Endomethasone N slowed down bone tissue healing process by showing the signs of prolonged inflammation in bone tissue in which it has been implanted. Extension of the healing process is reflected in the slow replacement of fibrovascular connective tissue with newly formed bone tissue.

Abstract Hypodontia of upper lateral incisors is significant aesthetic problem in young people. Ideal solution to this problem would be an implant placement, but there is a problem of unfinished growth and development. It is therefore necessary to have a temporary solution in order to maintain normal stomatognathic system functions and solve aesthetic problems until the final restoration is placed. The aim of this study was to show the possibility of treating hypodontia of permanent upper lateral incisors by creating adhesive bridge in one visit. A 15-year-old patient was referred to the Department for Prosthodontics, School of Dental Medicine in Belgrade with hypodontia of permanent upper lateral incisors. The patient had braces until 14 years of age after which she was rehabilitated with partial denture that was neither aesthetically nor functionally acceptable solution for her and significantly affected her emotional security. The adhesive bridge was made using GC composite fibers and a set of GC composite materials for the purpose of temporary replacement of missing teeth. This treatment provided good functional and aesthetic results. The space for the placement of two endosseous implants is preserved and a period of adaptation positively influenced the patient’s social development in sensitive adolescent age.

Abstract Introduction During the first two years of life children’s nutrition is mostly based on frequent, liquid and sweetened meals which can cause Severe-Early Childhood Caries (S-ECC) development. The aim of this research was to determine the relationship between dietary habits and S-ECC in children up to 24 month-old living in Banja Luka, Bosnia and Herzegovina. Methods Cross-sectional study included representative sample of 192 children. Before dental examination of children, each parent/caregiver was interviewed about the basic info, socio-demographic characteristics and children's eating habits. The questionnaire was conducted as interview (“face to face”). Subjects were divided into two groups: the first group - children with S-ECC and the second group - caries free children. For statistical analysis and presentation of results SPSS 16.0 for Windows, MS Office Word and Microsoft Office Excel were used. Results In the study sample 34.9% of children were suffering from S-ECC. About 50% of children who were breast-fed at night after first tooth eruption had S-ECC. The use of baby bottle with milk or other sweetened content during bedtime and during the night was identified as significant caries risk factor (P <0.05). Conclusion Nighttime breastfeeding, use of bottle with milk during bedtime/nighttime or other sweetened content during night after eruption of first primary tooth were strongly associated with S-ECC in the examined children.
在生命的头两年，儿童的营养主要是基于频繁的、流质的和甜的食物，这可能导致严重的早期儿童龋齿(S-ECC)的发展。本研究的目的是确定生活在波斯尼亚和黑塞哥维那巴尼亚卢卡的24个月以下儿童的饮食习惯与S-ECC之间的关系。方法横断面研究纳入192例儿童的代表性样本。在儿童牙科检查前，对每位家长/照顾者进行了基本信息、社会人口特征和儿童饮食习惯的访谈。问卷采用面谈(“面对面”)方式进行。将受试者分为两组:第一组为S-ECC儿童，第二组为无龋儿童。采用SPSS 16.0 For Windows软件、MS Office Word软件和Microsoft Office Excel软件进行统计分析和结果呈现。结果研究样本中34.9%的儿童患有S-ECC。首次萌牙后夜间母乳喂养的儿童约有50%患有S-ECC。睡前和夜间使用含有牛奶或其他含糖成分的奶瓶是显著的龋齿危险因素(P <0.05)。结论夜间母乳喂养、睡前/夜间使用奶瓶或乳牙萌出后夜间使用其他含糖饮料与S-ECC密切相关。

Abstract Introduction Saliva is a complex secretion, which plays an important role in maintenance of oral health. Analysis of saliva is fast, simple and non-invasive, and it is increasingly used as a biological sample for determination of various biochemical markers. The aim was to determine the influence of unstimulated saliva collection methods for measuring electrolytes concentration (sodium, potassium, calcium), pH and buffer capacity of saliva in healthy subjects. Material and methods 30 healthy subjects, males and females, aged 18 to 20 years, without oral and systemic diseases were included in the study. Unstimulated saliva samples were taken using a special tube (Salivette) and via direct spitting into the test tube. The concentrations of sodium and potassium were determined by flame emission photometry while spectrophotometry was used for calcium concentration. For the analysis of pH value of saliva pH-meter was used, while saliva buffer capacity was determined by titration with HCl (0.005 mol/L). Results The level of sodium in unstimulated saliva collected in test tubes was 8.43 ± 3.92 mmol/L and in special tubes 7.90 ± 4.33 mmol/L. Potassium level in unstimulated saliva collected in test tubes was 13.62 ± 0.99 mmol/L while in special tubes it was 13.54 ± 0.94 mmol/L. Mean values of sodium and potassium in unstimulated saliva didn’t show statistically significant difference in their concentrations between the two methods of collecting saliva. In contrast to these electrolytes, calcium concentration was higher in the samples of saliva collected with special tubes (2.04 ± 1.05 mmol/L) compared to the samples taken by direct spitting into the test tube (1.38 ± 1.18 mmol/L) with statistically significant difference (p < 0.05). By analyzing the pH of unstimulated saliva it was found that the average pH value of saliva collected with special tubes was 7.05 ± 0.32, and after direct spitting into test tubes it was 7.35 ± 0.41. Buffer capacity of saliva in healthy subjects was lower after taking with special tubes (5.18 ± 0.74) compared to test tubes (5.36 ± 0.85), but without statistical difference. Conclusion Unstimulated saliva collecting methods using cotton pads (salivette) and direct spitting in the test tube did not affect the value of pH, buffer capacity, the concentrations of sodium and potassium, but affected the concentration of calcium in saliva from healthy subjects.

Abstract Introduction This pilot study was aimed to compare pulpal pain provoked by electrical and thermal (cold) stimuli in healthy young women during various phases of menstrual cycle and postmenopausal women. Material and methods The study included 20 regularly menstruating healthy women and 20 postmenopausal women. Electrical (electrical pulp tester) and cold (refrigerant spray) stimuli were performed on mandibular central incisors, twice in regularly menstruating (menstrual and luteal phases) and once in postmenopausal women. Results were expressed as pain threshold values for electrical pulp stimulation (0-80 units) and pain intensity scores (visual numeric scale, from 0 to 10) for cold stimulation. Results In young women, higher pain electrical threshold (p=0.484) and pain sensitivity score (p=0.015) were observed in luteal in comparison to menstrual phase. In postmenopausal women, electrical pain threshold was significantly higher while pain intensity score was significantly lower than in young women, regardless of the menstrual phase and painful stimuli. Conclusion Lower responsiveness to dental pulp pain was obtained in young women in luteal phase and postmenopausal women.

Abstract Peripheral giant cell granuloma (PGCG) or “Epulis gigantocelularis” is the most common oral lesion that originates from giant cells. It typically manifests in the form of soft tissue tumor purple-red or red-watery color consisting of multinuclear giant cells in the mononuclear stroma and extravascular erythrocytes. This lesion is not considered true neoplasm, rather reactive lesion stimulated by local irritation and trauma. However, the cause is not known with certainty. This paper presents a 13-year-old boy with a large lesion in the region of right maxillary canine that was retained in jaw despite favorable vertical position and available space to accommodate in the dental arch. The lesion was completely removed under local anesthesia and histopathological findings confirmed the diagnosis of PGCG. Postoperative period went without complications. After four months additional surgical procedure was needed due to the recurrence, which after tooth naturally erupted and positioned in the dental arch.

After four months additional surgical procedure was needed due to the recurrence, which after tooth naturally erupted and positioned in the dental arch.","PeriodicalId":52984,"journal":{"name":"Stomatoloski glasnik Srbije","volume":"32 1","pages":"139 - 144"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89575706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract This paper analyzes mechanisms of fluorapatite mechanochemical synthesis and its structural characteristics. Several studies of Jokanovic et al. published in appropriate journals and the book “Nanomedicine, the biggest challenge of the 21st century” are the base for this article. Characteristics of obtained materials show numerous biological advantages associated with the specific structural design of material during the process of synthesis. X-ray diffraction (XRD) and infrared spectroscopy with Fourier transform (FTIR) were used for studying the processes of fluorapatite synthesis.

Abstract Traumatic neuroma represents reactive hyperplasia of irregularly positioned Schwann neurofibril cells and connective tissue - stroma that develop as a result of unsuccessful attempts to regenerate peripheral nerve after injury. This paper presents the case of a patient with painless traumatic neuroma of the lower lip formed in the same place where he previously had surgically removed salivary cyst of minor salivary gland - mucocele. Histopathological examination confirmed the diagnosis of traumatic neuroma.
