Početak sveučilišne nastave iz stomatologije i utemeljenje Klinike za stomatologiju vezani su uz ime dr. Eduarda Radoševića, a klinička stomatološka djelatnost za Otorinolaringološku kliniku ...Medicinskog fakulteta u Zagrebu. Daljnjim razvojem kliničke djelatnosti sve važnija postaje i djelatnost ambulatorija te se on već 1934. pretvara u mali klinički odjel. U tom dugom razdoblju stvarala se suvremena Klinika za stomatologiju KBC-a Zagreb i na kraju je nastala ustanova s više od 150 zaposlenih stručnjaka koji razvijaju sve danas priznate kliničke discipline u devet kliničkih i fakultetskih zavoda na današnjoj lokaciji u Gundulićevoj ulici 5. Gotovo svi nastavnici i suradnici u nastavi, uključujući i većinu pomoćnog medicinskog osoblja, zaposleni su istodobno s dijelom radnog vremena na Fakultetu i u Klinici. Stručni sastav Klinike čine djelatnici u znanstveno-nastavnim
te suradničkim zvanjima i među njima je više od pedesetero doktora znanosti. Po broju i znanstveno-nastavnoj strukturi djelatnici Klinike za stomatologiju KBC-a Zagreb danas predstavljaju jedinstveni potencijal stručnog stomatološkog kadra u Republici Hrvatskoj.
The aim of this study was to investigate retention of composite fissure sealant polymerized with standard and soft-start technique after a three year clinical trial. One hundred teeth were divided ...into two groups (A&B) of teeth and sealed with composite material (Visioseal, 3M Espe) using split mouth design. Sealants were polymerized using standard (Group A) and soft-start (Group B) techniques with commercial polymerization unit (Elipar Highlight, 3M Espe). Retention rate in Group A was 72%. In 14 teeth sealant was partially or completely missing. Group B showed retention rate of 80%. Sealant was partially or completely missing in 10 teeth. Six new caries lesions in Group A (3) and B (3) were detected. Mann-Whitney test did not reveal significant differences between the polymerization techniques. After three years complete retention of sealants, regardless of the group, was 76% (76 teeth) with six new caries lesions. Soft-start polymerization showed a comparable retention rate as the standard polymerization technique.
The aim of this study was to establish effect of 14 day consumption of commercially available yoghurt containing Lactobacillus rhamnosus ATCC53103 - LGG (Bioaktiv LGG, Dukat, Croatia) on ...Streptococcus mutans and Lactobacillus spp. salivary counts in children. Twenty five patients, 6-10 yr old participated in the study. At the inclusion in the study caries risk for every patient was evaluated. The saliva samples were tested with chair side kits for saliva buffer capacity (CRT buffer, Vivadent, Schaan, Liechtenstein), S. Mutans and Lactobacillus counts (CRT bacteria test, Vivadent, Schaan, Liechtenstein). Seven, 14 and 30d after yoghurt consumption saliva samples were tested again with CRT buffer and CRT bacteria tests. Obtained data were analyzed using chi2 and Kruskal-Wallis tests. Results showed significant increase in saliva buffer capacity 30d after yoghurt consumption. S. Mutans salivary counts were significantly decreased after 30d. Significant differences in Lactobacillus counts were not observed. It could be concluded that daily consumption of yoghurt containing LGG have an inhibitory effect on oral pathogenic bacteria and may be beneficial in caries prevention.
A discriminant analysis was performed in a sample of 303 children with developmental disorders (DD) and 303 healthy controls (C) in order to test whether some oro-dental and physical minor anomalies ...could discriminate these groups of children. DD sample comprised 176 mentally retarded (MR) children. 70 children with impaired hearing (IH) and 57 children with impaired vision (IV). The control group included 303 healthy subjects, matched for sex and age. The analysis comprised seven common oral and dental anomalies: median diastema, hypodontia, impacted teeth, microdontia, dens invaginatus, upper lip frenulum and frenulum of the tongue. Minor physical anomalies were assessed by the method proposed by Waldrop et al., as the average number of minor anomalies per individual (W1) and as the weighted score of minor anomalies (W2). Three discriminant functions were obtained by analysis of nine initial variables. Distinct discrimination and considerable distances were found between the centroids of the controls and all groups of DD children. The first two discriminant functions were significant for discrimination between the groups and they explained 98.6% of the total variance. The first function contained 90.2% of information and was defined by the number and weighted scores of minor anomalies. The second variable explained 8.4% of the total variability and was defined by three dental anomalies. The results obtained by the discriminant analysis show that application of dental and minor physical anomalies enables discrimination between the group of healthy children and the groups of children with different developmental disorders.
Hypohidrotic ectodermal dysplasia (HED) is characterized by clinical manifestations of severe hypodontia or anodontia, hypotrichosis, hypohidrosis, and specific facial appearance. Affected males show ...complete expression of clinical features of this condition. Their mothers, who are gene carriers, express only some signs, which are usually very mild. Currently available clinical methods are not sufficient for routine identification of the HED heterozygous gene carriers. The purpose of this study was to identify and describe the facial characteristics of HED patients and their mothers and to evaluate the usefulness of craniofacial pattern profile analysis (CFPP) in the diagnosis of this syndrome and the detection of gene carriers. In this study six affected males and their mothers were evaluated. Z-scores for each variable were calculated and compared with age- and sex-matched controls. Anthropometric analysis showed a specific dysmorphic pattern in CST patients that includes decreased skull base width (t-t: -1.67 Z); decreased forehead width (ft-ft: -1.8 Z), decreased midface depth (sn-t: -2.02 Z), markedly decreased total facial height (n-gn: -3.4 Z), and markedly decreased maxillary arc (t-sn-t: -2.5 Z). Gene carriers showed a similar tendency in their pattern profiles. They showed the same tendency towards lower Z-values for forehead width, facial height, and mouth width. The values for these measurements were between those of the affected and healthy controls. The most pronounced findings were increased head width (eu-eu: +2.83 Z), increased lower face width (go-go: +2.06 Z), and reduction of total facial height (n-gn: -0.95 Z). They also displayed increased nose width (al-al: +2.41 Z) and increased biocular distance (ex-ex: +2.01 Z). When used in conjunction with other methods the anthropometrics pattern profile analysis can considerably enhance detection of gene carriers for HED and increase objective assessment of the craniofacial region in HED patients.
Objective. The aim of this study was to assess the retention rate of glass ionomer cement (GIC) fissure sealants heated during setting time.
Methods. One hundred and twelve teeth with ...well‐delineated fissure morphology were sealed with composite resin and GIC. Composite resin (Helioseal F, Vivadent) was used in control group A (56 teeth). GIC (Fuji VII, GC) was applied using split‐mouth design with conditioning in group B (26 teeth) and without surface conditioning in group C (30 teeth). GIC was heated with external heat source (Elipar Trilight, Espe) for 40 s during the setting time according to the manufacturer's instructions. Fissure sealants were evaluated 1 year after clinical service.
Results. Retention rate in group A was 80.4% after 1 year of clinical service. Group B showed retention rate of 30.8%, and group C of 26.7%. Two new caries lesions were detected in groups B and C. Significant differences in retention between the composite group and GIC groups were obtained by Kruskal–Wallis and Mann–Whitney tests.
Conclusion. It could be concluded that retention rate of GIC sealing treated with heat during setting time was significantly lower than retention of conventional composite resin. The heating procedure during setting of GIC sealants cannot be recommended as routine treatment in clinical practice.
Neka djeca češće su pogođena traumama zuba od ostalih. Visoka prevalencija zapažena je kod dječaka i djevojčica iz obitelji s niskim socijalno-ekonomskim statusom (SES). Svrha U ovom se istraživanju ...željelo istražiti razlikuje li se SES djece s ponovljenim ozljedama od onoga dječaka i djevojčica s jednom ozljedom. Cilj je također bio ustanoviti je li nizak SES rizični čimbenik za ponavljanje ozljeda kod djece s traumama zuba. Materijal i metode Istraživanje je provedeno na uzorku od 151 djeteta u dobi od 6 do 17 godina (99 dječaka i 52 djevojčice) liječenih zbog traumatskih ozljeda zuba. Njihov socijalni status procijenjen je Hollingsheadeovim dvofaktorskim indeksom socijalnog položaja. Svi ispitanici razvrstani su u tri socijalna razreda – gornji, srednji i donji. Skupine su uspoređene primjenom Studentova t-testa i χ2 testa. Primijenjeni su također Pearsonovi koeficijenti korelacija i omjeri izgleda (OR) za procjenu povezanosti SES-a s ponovljenim ozljedama. Rezultati Većina djece s ponovljenim ozljedama potjecala je iz donjega socijalnog razreda, pokazujući prosječnu vrijednost indeksa socijalnog položaja (ISP) od 42,89 u usporedbi s ispitanicima s jednom ozljedom kod kojih je taj indeks bio 38,5 (p = 0,018). Pacijenti iz donjega socijalnog razreda imali su 1,54 puta veći rizik za ponavljanje ozljeda od onih iz gornjega socijalnog razreda (OR = 1,542; CI = 0,564 – 4,214). Zaključak Djeca s ponovljenim ozljedama značajno se razlikuju od djece s jednom ozljedom, kad se uzmu u obzir ISP i SES. Dakle, ako dijete pripada donjem socijalnom razredu ima povećani rizik od ponavljanja ozljeda.
Svrha: Cilj ovog in vitro istraživanja bio je utvrditi učinak fluoridnih gelova i lakova u odnosu na CPP-ACP kompleks na sprječavanje demineralizacije cakline. Materijali i Metode: Caklinski blokovi ...su ispolirani, podijeljeni u osam grupa i izloženi dnevnom cikličkom režimu. Tri skupine su tretirane 10 minuta s fluoridnim gelovima: Fluorogal, Fluor Protector Gel and Cervitec Gel, jedna je tretirana samo s GC Tooth Mousse i jedna je tretirana s GC Tooth Mousse (Recaldent CPP-ACP 10.0%).. Preostale tri grupe su tretirane fluoridnim lakovima: Fluoridin Gel N5, Bifluorid 12 i Fluor Protector. Oni su premazivani jedanput na tjedan prije demineralizacijskog razdoblja. Svi uzorci su čuvani u umjetnoj slini između i nakon ciklusa. Površinska mikrotvrdoća (SMH) uzoraka je mjerena na početku i nakon 12 dana koristeći HMV-2000 (Shimadzu, Japan). Postotak promjene SMH (% SMH) je izračunat nakon cikličkog režima. Podaci su analizirani t-testom za individualne usporedbe (p<0,05). Rezultati: Statistička analiza t-testom pokazala je značajnu razliku između SMH prije i nakon tretmana fluoridima u svim skupinama. Sve skupine tretirane fluoridnim gelovima, lakovima i GC Tooth Mousseom pokazale su povećanje SMH. Nije bilo statistički značajne razlike između postotaka promjene SMH cakline između skupina. Nije bilo statistički značajne razlike između fluoridnih gelova, lakova i GC Tooth Moussea. Zaključak: Rezultati dobiveni u ovom istraživanju pokazali su da fluoridni lakovi, gelovi i Tooth Mousse učinkovito sprječavaju demineralizaciju u eksperimentalnim uvjetima.
