   Title in English:	Antibacterial activity of root-end filling materials
   Title in Croatian:	Antibakterijska svojstva retrogradnih punila korijenskih kanala
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Purpose: The present study was undertaken to evaluate and compare the antibacterial effectiveness of five root-end filling materials. Material and methods: The agar diffusion method was employed to evaluate the inhibition zone provided by the following root-end filling materials: Pro Root MTA, Portland cement, Super-EBA, IRM, Sealer 26, and silver amalgam. The target microorganisms included five anaerobic bacterial species (Porphyromonas gingivalis, Parvimonas micra, Fusobacterium nucleatum, Propionibacterium acnes and Eubacterium saburreum) and two facultative bacterial species (Actinomyces viscosus and Enterococcus faecalis). Results: Sealer 26 demonstrated the largest inhibitory effects on all species tested. IRM and Super-EBA were inhibitory only to P. gingivalis, but this effect was far less pronounced as compared to Sealer 26. MTA, Portland cement, and amalgam proved ineffective against all species tested. Conclusion: These findings revealed that Sealer 26 has more pronounced antibacterial effects when compared to other commonly used root-end filling materials.

   Title in English:	Antibacterial effect of mineral trioxide aggregate and amalgam
   Title in Croatian:	Antibakterijski učinak agregata mineralnog trioksida i amalgama
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	The purpose of this study was to evaluate the antibacterial effect of root-end filling materials, MTA and amalgam, by agar diffusion test. Materials and methods: Blood agar plates were inoculated with bacteria Streptococcus mutans, Streptococcus mitis, Lactobacillus acidophilus, Staphylococcus aureus and Enterococcus faecalis each, and a polymicrobial suspension consisting of all the tested bacteria. Material samples were divided among the inoculated plates, and after 48 hours of incubation, the diameters of the inhibition zone (IZ) were recorded. Results: The strongest antibacterial effect of MTA was against Streptococcus mutans (IZ = 7.6 mm, sd 1.0), followed by Streptococcus mitis and Lactobacillus acidophilus (IZ = 7.3 mm, sd 0.5). The inhibition zone (IZ) for Enterococcus faecalis was 5.6 mm (sd 0.7), and for the polymicrobial suspension 5.3 mm (sd 1.0). Staphylococcus aureus was the only bacteria MTA did not show any antibacterial effect against. Amalgam showed no antibacterial effect against any of the bacteria tested. Conclusion: MTA showed antibacterial effect against 4 of 5 tested bacteria and the polymicrobial suspension, while amalgam did not inhibit the growth of any of the bacteria tested.

   Title in English:	The effects of periodontal therapy on C-reactive protein and periodontal pathogens in periodontitis patients
   Title in Croatian:	Utjecaj parodontoloπke terapije na C-reaktivni protein i parodontne patogene kod pacijenata s parodontopatijom
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Objective. Recent epidemiological studies have shown that individuals with periodontitis have significantly increased risk of developing coronary heart disease. Although the mechanism responsible for the relationship between periodontal disease and cardiovascular events is not fully understood, it is hypothesized that the removal of infection and inflammatory burden of periodontitis by therapy would be accompanied by a decrease in levels of the inflammatory marker C-reactive protein and a decreased risk of coronary heart disease. The aim of the present study was to determine whether the presence of chronic periodontitis and periodontal pathogens and subsequent periodontal treatment could influence the serum levels of C-reactive protein in a Serbian cohort. Material and Methods: Fifty adults with moderate to severe periodontitis who underwent complete mouth disinfection were evaluated to determine if periodontal therapy would result in decreased periodontal inflammation and lower serum levels of an inflammatory marker. Subjects underwent measuring of periodontal disease severity and serum C-reactive protein, and periodontal pathogens (Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans) at the time of the baseline visit and again 6 and 12 months after treatment. Serum levels CRP were also obtained from 25 subjects without periodontitis in a control group. Results: The levels of CRP in the serum seemed not to be lower than those reported in other population in Western European countries. There were significant changes in clinical periodontal values, CRP levels and presence of periodontal pathogens when baseline values were compared to those taken after periodontal treatment completion. Conclusion: The obtained results confirm the hypothesis that periodontal therapy may contribute to elimination of periodontal inflammation and periodontal pathogens, and reduce serum level of CRP. Periodontitis may contribute to the systemic nflammatory burden of affected individuals since it was shown that periodontal therapy may decrease presence of periodontal pathogens and inflammatory markers.

   Title in English:	Evaluation of the prevalence of dental anomalies in children in the canton of Sarajevo
   Title in Croatian:	Evaluacija učestalosti dentalnih anomalija kod djece u Sarajevskom kantonu
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Objectives: The aim of this study was to evaluate the prevalence of dental anomalies in preschool and school children of the Canton of Sarajevo and differentiation of the relative share of hereditary and nonhereditary factors in the phenotypic expression of dental anomalies. Subjects and Methods: We analyzed a sample of preschool children and school children of both sexes from six kindergartens and six elementary schools in the Canton of Sarajevo. The study included a total of 740 children, out of which 270 were preschool children (123 boys, 147 girls), and 470 school children (231 boys, 239 girls). The prevalence of dental anomalies was estimated according to frequency of occurance of dental anomalies in the sample. To compare the observed prevalence of certain dental anomalies with European and world populations, the test for proportion differences was used, a variant of the chi-square test with limit of the statistical significance of p <0.05. A significant difference between the subjects according to gender was found using the same test. The statistical analysis was performed using the scientifically verified software MedCalc Ver. 9.2.0.0. Results: There was a tendency toward increase of dental anomalies in children of female sex, based on the observed sample of preschool children. The following percentage distribution of dental anomalies was found: macrodontia (27%), fusion (24%), hypoplastic type of AI (13%), microdontia (13%), hypocalcification type of AI (10%), hypodontia (8%) and gemination (5%). The following percentage representation of various dental anomalies was determined in a sample of school children: hypodontia (42%), macrodontia (27%), microdontia (25%), hypoplastic type of AI (4%) and fusion (2%). Conclusion: In a sample of preschool children, dental anomalies were observed in 14.8% and among school children this percentage was 11.7% of the total number of subjects. The percentage of dental anomalies in children in the Canton of Sarajevo was compared with reference data from the literature and was within the expected range.

   Title in English:	Light intensity of curing units in dental offices in Zagreb, Croatia
   Title in Croatian:	Intenzitet svjetlosti polimerizacijskih uređaja u ordinacijama dentalne medicine u Zagrebu, Hrvatska
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Objective: Photopolymerization unit is an essential part of every dental office. The intensity of light curing units gradually decreases with time and can lead to poor polymerization, which cannot be detected clinically immediately after illumination. The purpose of this study was to examine whether the intensity of light curing units in dental offices in Zagreb satisfies minimum operational requirements. Materials and methods: The light intensity of 111 curing units was measured using radiometer (Bluephase® meter, Ivoclar Vivadent, Schaan, Liechtenstein). Six measurements were taken for each unit, three at the beginning of illumination and the other three at 35-40 seconds from the beginning. Data were also collected about the type of curing unit, manufacturer, age, frequency of use and the existence of integrated radiometer. Results: Light intensity lower than 300 mW/cm2 had 34% of curing units and 44% lower than 400 mW/cm2. The average light intensity of the remaining curing units was 675.3 mW/cm2. This study included photopolymerization units used in Zagreb which were five years old on average. Conclusion: Though the average light intensity of curing units in Zagreb fulfill the general requirements for efficient polymerization of composite resin materials, the fact that more than one third of curing units are ineffective should alert dentists to regularly monitor their appliances.

   Title in English:	The buffering capacity of probiotic yogurt
   Title in Croatian:	Puferski kapacitet probiotičkih jogurta
   Type of Article:	original scientific paper
   MeSH:	(no MeSH data)
   Abstract:	Aim: The potential buffering role of probiotic yogurt has not been investigated. The aim of the study was to determine the pH, titratable acidity of a selection of various probiotic yogurts, their buffering effects with an emphasis on the pH range in which the buffer is efficient. Material & Methods: A quantity of 25 ml of each yogurt was titrated with 1 mol/L sodium hydroxide, added gradually by 0.5 ml, until the pH reached 10 to assess the total titratable acidity - a measure of probiotic yogurt’s own buffering capacity. Results: The initial pH was the lowest for Activia peach yogurt (4.40± 0.14) and the highest for Danone natural yogurt (5.29± 0.10). The buffering capacities can be listed as follows: Danone natural >Danone peach >Activia plain >Activia strawberry >Activia peach. There were no statistically significant differences observed between yogurts within any of the five groups compared as a whole with one another. (p >0.05). Conclusions: Buffering capacities of probiotic yogurts should be undermined.

   Title in English:	Oral juvenile hyaline fibromatosis: a rare entity
   Title in Croatian:	Rijedak slučaj oralne juvenilne hijaline fibromatoze
   Type of Article:	professional paper
   MeSH:	(no MeSH data)
   Abstract:	Juvenile hyaline fibromatosis is an exceedingly rare disorder of infants and children which appears to have autosomal recessive inheritance. It is characterized by multiple, slowly growing dermal or subcutaneous tumors, especially in the head and neck region and upper trunk, often associated with gingival hypertrophy, severe flexural limb contractures and bone lesions. There is no mental retardation. Histologically, these lesions are composed of copious eosinophilic, homogenous ground substance with unevenly dispersed fibroblasts. Lesions excised in early stages are more cellular. The precise nature of the eosinophilic hyaline material is not known. Recently, a defect on chromosome 4q21 associated with the locus of the capillary morphogenesis gene – 2, has been demonstrated. The differential diagnosis of juvenile hyaline fibromatosis includes infantile systemic hyalinosis, which is now known to be allelic. Currently, no widely accepted effective treatment exists for juvenile hyaline fibromatosis or infantile systemic hyalinosis. Infantile systemic hyalinosis and juvenile hyaline fibromatosis are sometimes difficult to separate since they show significant overlap. We report one such unusual case of juvenile hyaline fibromatosis in a 10 year old female presenting mainly with gingival hyperplasia.

   Title in Croatian:	Imedijatna implantacija nakon enukleacije odontogene ciste: opis slučaja
   Type of Article:	professional paper
   MeSH:	(no MeSH data)
   Abstract:	The purpose of this case report is to present a bone defect restoration after radicular cyst enucleation using guided bone regeneration procedure with immediate implant insertions. The patient was a 50-year old female with an odontogenic cyst of the first premolar in the right maxilla and a second molar root resorption caused by an impacted third molar. The surgical procedure involved a cyst enucleation followed by guided bone regeneration, immediate implantations, and surgical removal of the impacted third molar. The patient was supplied with an interim partial denture during the osseointegration period. Six months after surgical treatment, the implant stability was assessed by resonance frequency analysis. Mean scores for the first premolar and first molar implants were 74 and 78, respectively. Both implants were monitored clinically and radiographically during the following 6-month period. Implant stability was considered adequate. Neither clinical nor radiological complications were present throughout the postoperative 6-month period. The implants were used to support a fixed partial denture. Immediate implantations after odontogenic cyst enucleation minimized the number of surgical procedures and led to a satisfactory result.

   Abstract:	On the occasion of the 30th anniversary of Ivo Miše’s passing away, I consider it my duty to look back on the life path of my teacher, a man who has made his mark on the important times of birth and development of the School of Dental Medicine, University of Zagreb. As a dental practitioner (without university diploma), and later as a doctor of dental medicine, he recognized the importance of oral surgery, introduced it as a specialist field and defined its boundaries that, according to his views, largely crossed over the realm of dentoalveolar surgery. He published many papers and left many unpublished; these are the forgotten manuscripts which enabled his heirs to publish the first comprehensive textbook of oral surgery in Croatia that was used in all the dental schools of former Yugoslavia.
