Objective Giant cell lesions of the jaws (GCLJ) may rarely occur in the setting of RASopathy syndromes such as Noonan syndrome or neurofibromatosis I. Recently, central giant cell granulomas (CGCG), the most common of the GCLJ, have been recognized as benign neoplasms characterized by Ras/MAPK signaling pathway mutations. This provides a rational basis for understanding GCLJ in RASopathy syndromes as syndromically occurring CGCG. This review aims to summarize the clinicopathologic features of syndromic CGCG and to review the salient clinical and craniofacial features of the syndromes in which they may rarely occur. Material and Methods An electronic search in 3 databases was performed, looking for GCLJ/CGCG in RASopathy syndromes. Results 124 CGCG in 56 patients were identified across 6 RASopathy syndromes. Median age at syndromic CGCG diagnosis is 11 years; 69.6% (39/56) patients developed two or more CGCG; 58.9% (33/56) presented with bilateral posterior mandibular CGCGs, mimicking cherubism. Of 88 CGCG with follow-up, 22.4% (13/58) of excised/resected CGCG recurred while 46.7% (14/30) of monitored CGCG showed continued growth. Conclusion Syndromic CGCG involves multiple RASopathy syndromes and may mimic cherubism or, when solitary, sporadically occurring CGCG. Familiarity with other clinical findings of RASopathy syndromes is critical for appropriate diagnosis and patient management.

Objectives This study aimed to evaluate the effects of root canal irrigation on maximum operative torque and vertical force of Wave One Gold Primary (WOG), Reciproc Blue R25 (RB) and Protaper Next X2 (PTN) endodontic rotary instruments during simulated root canal preparation in the presence and absence of a surfactant “benzalkonium chloride”. Material and Methods A custom-made automated irrigation and torque/force analyzing device connected with endomotor was used for the study. Acrylic resin blocks with simulated curved root canals of 35° were randomly assigned to 6 groups for each file. The following irrigants were used during simulated root canal preparation with continuous rotation or reciprocation motion with pecking mode: 5% NaOCl and 5% NaOCl with 0.84% benzalkonium chloride. Maximum torque and vertical force values of files were recorded during preparation. Results BAC addition to NaOCl did not significantly affect maximum torque values of instruments (p>0.05). WOG generated lowest torque value compared with PTN and RCB in both groups (p<0. 05). RB generated higher vertical force compared with WOG and PTN instruments in NaOCl+BAC group. The surface modifier decreased the maximum force value of WOG instrument (p<0.05). Discussion Surfactan addition to NaOCl had no negative effects on maximum torque and force of the instruments.
目的研究在存在和不存在表面活性剂“苯扎氯铵”的情况下，根管冲洗对Wave One Gold Primary (WOG)、Reciproc Blue R25 (RB)和Protaper Next X2 (PTN)根管旋转器械在模拟根管预备过程中最大操作扭矩和垂直力的影响。材料与方法采用自制的自动灌洗及扭矩/力分析装置，与内源性马达连接。采用模拟根管弯曲度为35°的丙烯酸树脂块，每个锉随机分为6组。在模拟根管预备过程中，使用连续旋转或往复运动的灌洗剂:5% NaOCl和5% NaOCl加0.84%苯扎氯铵。在制备过程中记录了锉的最大扭矩和垂直力值。结果BAC加入NaOCl对仪器最大扭矩值无显著影响(p < 0.05)。与PTN和RCB相比，两组WOG产生的扭矩值最低(p<0。05)。NaOCl+BAC组RB产生的垂直力高于WOG和PTN组。表面改性剂降低WOG器械的最大受力值(p<0.05)。讨论NaOCl中加入表面活性剂对仪器的最大扭矩和力没有负面影响。

Introduction Caries has a harmful impact on oral and general health and is a major public health problem among children and adolescents. The objective of present study was to investigate into dental caries, oral hygiene, the frequency of brushing habits and dental visits among 15- year- old adolescents. Material and methods This cross-sectional study was carried out on a random sample of 323 15- year- old adolescents in different schools and municipalities of Kosovo. Oral clinical examination and self-administered questionnaire were used to obtain information about dental caries and oral health practices. Oral hygiene and caries status in permanent dentition was assessed through the DMFT index and Oral Hygiene Index - Simplified (OHI-S). The level of statistical significance was set at p<0.05. Results The total mean of the DMFT index was 3.21 ± 2.193, while component D of the DMFT index dominated in both genders, with slightly higher values in boys compared to girls (2.15±2.092, and 1.91±1.919). The mean OHI-S index of adolescents aged 15 was found to be 1.945±3.926. Over 50% of schoolchildren brush their teeth only once per day and they have visited the dentist only when it was necessary. Irregular tooth-brushing, dental visits and poor oral hygiene index were significantly related to dental caries. Conclusion The results of the study showed poor oral health status among 15- year- old adolescents in Kosovo. There is an emergent need for caries-prevention programs focusing on oral health and healthy habits.

Objectives Dentin thickness in concave areas of the root creates risk for complications such as strip perforation during endodontic treatment. The study aims to examine dentin thickness of the danger (DZ) and safety zone (SZ), canal configuration, and the presence of isthmus in the mesiobuccal root of maxillary molars. Material and Methods Cone-beam Computed Tomography (CBCT) images of 1251 teeth belonging to 642 patients were retrospectively reviewed. The dentin thicknesses at DZ and SZ in maxillary molars with one (MB) or two mesiobuccal canals (MB1, MB2) were measured at the 3 mm apical to the furcation level. Vertucci's canal configurations and the isthmus rate were recorded. The Chi-square test andThe Student’s t-test were performed. Results MB2 rate was higher in maxillary first molars (61.68%) than second molars (39.36%). Isthmus rates were 27.3% and 44.11% in first and second molars. DZ thickness was thinner than the dentin thickness in the SZ in both first and second molars with one or two mesial canals (p< 0.05). In teeth with single canal, the mean DZ thickness was 0.88mm. In teeth with two canals, the mean DZ thicknesses were 0.83mm and 0.80mm for MB1 and MB2 canals, respectively. Conclusion MB2 rate was higher in the first molar (61.68%), and the isthmus rate was higher in the second molar (44.11%). DZ and SZ were thinner in MB2 than in MB1 at the maxillary molars with two mesial canals. The results indicated that more conservative preparation must be applied to the MB2 canal in the maxillary molars.

Objectives The study aimed to compare the color stability of two different light-cured composites after immersion in three liquids and the effectiveness of 16% carbamide peroxide (CP) in removing the discoloration. Material and methods Color stability of a microhybrid (Z250, 3M ESPE) and nanocomposite (Z550, 3M ESPE) was evaluated after immersion in instant coffee, tea, Coca-Cola, and deionized water as a control group (n=5). Samples were kept in liquids for four hours daily at 37°C for 30 days. Furthermore, 16% CP was applied for the following 14 days, simulating night whitening. A digital spectrophotometer was used for color measurement based on the CIEL*a*b* color coordinates. The color changes (∆E) were measured at baseline, after immersion in the beverages, and also after the teeth whitening procedure. Mixed and factorial ANOVA followed by Bonferroni’s post-hoc test were used for statistical evaluation (p≤0.05). Results Tested resin composites showed a color change over the acceptability threshold (ΔE*> 3.48) after immersion in coffee and tea. Nanocomposite reported a significant increase in discoloration in coffee after 30 days (p <0.05). The color of both materials significantly changed (p<0.05) along all three L*a*b* axes in coffee and tea to darker, yellow, and red. Whitening with 16% CP was effective in removing external discoloration in both examined composite materials. Conclusion Coffee and tea induced clinically detectable color changes in dental composites tested, with cumulative effects. Whitening represents an efficient method for the removal of surface discoloration in composite restorations.

Correct implant positioning poses a major challenge in modern dentistry and mismatch between the planned and final implant position is one of the most common treatment complications. A surgical guide or a template is a ''transmission device'' which enables the implant placement in the intended position as accurate as possible. Case study: A woman aged 60 came into dental office to resolve a single tooth loss in regions 15 and 24. Radiographic analysis and clinical examination showed a lack of transversal space in the regions of implantation. Considering the fact of having a narrow area available for implantation, a computer-guided implant therapy using the M-Guide system was selected. The treatment plan was a prosthetic restoration involving the placement of two implants in areas 15 and 24 and the fabrication of zirconium oxide crowns. After digital planning, a fully guided surgical protocol was performed. Immediately after implantation, a temporary suprastructure and temporary crowns were placed. After a period of osseointegration, a definitive prosthetic restoration was made.

Objectives The aim of this study was to evaluate the retreatment duration and efficacy of eucalyptol and tea tree oil in engine driven and manual retreatment of epoxy resin based endodontic filling in extracted human teeth. Methods and materials Sixty human single rooted teeth were randomly divided into two groups. The first group was prepared using hand files, and the second one using Reciproc system. Root canals were filled with gutta-percha points and AH Plus sealer. Retreatment was performed using K-reamers and Hedström files for the first group, and Reciproc instruments for the second group. Each group was divided into two subgroups (n=15) according to the retreatment solvent used (eucalyptol or tea tree oil). Root canals were longitudinaly split and analized with stereomicroscope (15x magnification). The surface of the remaining filling material was measured using an image processing software. Results There were no statistically significant differences in the area of residual filling material among used solvents, nor in applied technique. Retreatment with Reciproc instruments was significantly faster compared to retreatment using hand files. The manual retreatment technique was faster when tea tree essential oil was used as a solvent compared to eucalyptol. Conclusions Australian tea tree oil and eucalyptus oil were equally effective in removing endodontic filling material, but none of canals were completely free of the residual filling material. Retreatment with Reciproc instruments was faster compared to retreatment using hand files. The manual retreatment technique is faster when tea tree essential oil is used as a solvent compared to eucalyptol.

Objective To determine potential associations between dental and skeletal maturation and palatally displaced canines (PDC) considering gender and chronological age. Material and methods This study included pretreatment panoramic and lateral cephalometric radiographs of 43 subjects with PDCs and 203 randomly selected orthodontic subjects with normally erupted canines. Both groups were non syndromic patients. Chronological age of subjects was rounded and noted in years with decimal points and compared with chronological age according to Demirjian's dental age assessment. Skeletal maturation was determined by cervical vertebrae changes on cephalometric radiographs. Results Female subjects with PDC were more affected by left side canine displacement than males (p=0.027) with five times higher odds ratio (OR = 4.9; 95% CIL=1.2-19.7). A comparison of chronologic and skeletal age indicated that PDC subjects were skeletally younger than unaffected groups with statistically significant differences at the age of 10, 12 and 13. (p=0.05). Conclusion Young subjects with PDCs showed skeletal maturation delay compared to control group, indicating that skeletal maturation assessment could be one of unexplored predicting factors of a PDC, especially at the age between 10 and 13 years in both genders. Subjects with PDC showed intensive growth spurt after the age of 12 years in females, and after the age of 13 in males. Dental maturation delay showed no statistical significance in PDC prediction.

Objectives Swelling, pain and trismus after the surgical removal of the mandibular third molars are the most common and expected postoperative complications. The aim of this cross-sectional study was to assess the association of those postoperative complications and BMI after surgical removal of the mandibular third molars. Material and methods 84 patients who required the surgical removal of their lower third molar were enrolled in this study and were divided into 4 groups dependent on their BMI. Data were tested by one-way analysis of variance (Welch's ANOVA). The differences were tested by the intragroup using the Games-Howell test. Results The effect of BMI on pain had a statistically significant difference within the first 24 postoperative hours: 4 hours (p=0.014), 6 hours (p=0.034, p=0.049), 12 hours (p= 0.00.P=0.023), and 24 hours (p=0.010). For swelling and trismus in the exception on first postoperative day between underweight and normal weight groups (p=0.026), and underweight and overweight groups (p=0.014) no statistically significant correlation was found Conclusion BMI has an impact on a patient’s early postoperative recovery
