The Slovenian Version of the Oral Health Impact Profile Questionnaire (OHIP-SVN): Translation and Psychometric Properties

The aim of the study was to develop and to test the psychometric properties of the Slovenian version (OHIP-SVN) in the new cultural context. Construct validity was tested on 430 subjects, test-retest reliability on 60 subjects, internal consistency on 460 subjects, and responsiveness on 30 patients with a treatment demand (toothache). The significant association between the OHIP summary scores and the self-reported oral health (p0.05). The internal consistency showed high Cronbach’s alpha (0.97). The responsiveness was confirmed by the statistically significant difference between the mean OHIP score at baseline and follow-up (p<0.001) and by a considerable effect size in the patients with a treatment demand (0.515). The OHIP-SVN, as one of the first translation into one of the Slavic family of the languages proves that this instrument is suitable for the assessment of the Oral Health Related Quality of Life in Slovenia

Ocena korozijskih lastnosti titanovih dentalnihzlitin, izdelanih s SLM postopkom

Titanium alloys are known for their excellent biocompatible properties. The development of additive-manufacturing technologies has increased the interest in the use of Ti-6Al-4V, produced by selective laser melting (SLM) method, also in dentistry, i.e., prosthodontics and orthodontics. In the present paper, the effect of laser printing parameters in the selective laser melting (SLM) process on the porosity and corrosion behavior of Ti-6Al-4V dental alloy was metallographically and electrochemically studied. All the tests were performed in artificial saliva at 37 °C. Different forms of Ti-6Al-4V alloy were selected: a reference sample, i.e., pre-fabricated milling disc in wrought condition and four different 3D-printed samples made from Ti-6Al-4V powder using the SLM method, one being heat treated. Electrochemical, spectroscopic and hardness measurements were employed in the study. It was shown that the SLM-produced Ti-6Al-4V samples with different printing parameters have similar microstructural and electrochemical properties, while the electrochemical properties of a reference and thermally treated 3D-printed sample were different, most probably due to the change in the microstructure of the alloys. The corrosion properties were related to the microstructural properties as well as to the pore density.Titanove zlitine so znane po odličnih biokompatibilnih lastnostih. Razvoj aditivnih tehnologij je povečal zanimanje za uporabo Ti-6Al-4V, proizvedenega z metodo selektivnega laserskega taljenja (SLM) v zobozdravstvu - tako v protetiki kot v ortodontiji. V prispevku smo metalografsko in elektrokemijsko proučili vpliv parametrov laserskega tiska pri procesu selektivnega laserskega taljenja (SLM) na poroznost in korozijsko obnašanje dentalne zlitine Ti-6Al-4V. Vsi testi so bili opravljeni v umetni slini pri telesni temperaturi 37 °C. Izbrane so bile različne oblike zlitine Ti-6Al-4V: referenčni vzorec (v obliki diska za rezkanje v kovanem stanju) in štirje različni 3D natisnjeni vzorci iz prahu Ti-6Al-4V po metodi selektivnega laserskega taljenja (SLM), pri čemer je eden toplotno obdelan. Pri raziskavi so bile uporabljene elektrokemijske, spektroskopske metode in meritve trdote. Pokazalo se je, da imajo vzorci Ti-6Al-4V, izdelani s postopkom SLM, z različnimi parametri, podobne mikrostrukturne in elektrokemijske lastnosti, medtem ko so bile elektrokemijske lastnosti referenčnega in termično obdelanega 3D natisnjenega vzorca različne, najverjetneje zaradi različne mikrostrukture te zlitine. Korozijske lastnosti so bile povezane z mikrostrukturnimi lastnostmi, pa tudi z gostoto por

The Influence of the Extent of Color-Vision Deficiency on Shade-Matching Ability

Cilj: Željelo se procijeniti utjecaj stupnja oštećenja kolornoga vida na sposobnost vizualnog određivanja boje. Materijali i metode: Ispitano je šest skupina: kontrolna skupina (N = 68), skupina sa srednjom protanopijom (PMED) (N = 5), skupina s jakom protanopijom (PSTD) (N = 5), skupina s blagom deuteranopijom (DMID) (N = 5), skupina sa srednjom deuteranopijom (DMED) (N = 5) i skupina s jakom deuteranopijom (DSTD) (N = 8). Kolorni vid sudionika ocijenjen je monokularno primjenom Hardy-Rand-Rittlerova testa (HRR) i na HMC anomaloskopu MR (Rayleighev test). Završni test sastojao se od 15 zadataka za određivanja svjetline – zasićenja – nijanse s pomoću Toothguide Training Boxa. Izračunata je razlika u boji (ΔE*ab) i ocjena je podudaranja boja (ΣΔE*ab). Izračunati su prosjeci i standardne devijacije za ΣΔE*ab. Za statističku analizu podataka upotrijebljen je neovisni t-test i usporedba sredina (α = 0,05) za skupine s protanopijom te jednosmjerna analiza varijance (ANOVA) i Bonferronijev post-hoc test (α = ,05 ) za skupine s deuteranopijom. Rezultati: Skupina s PSTD-om imala je prosječnu vrijednost za ΣΔE*ab od 63,38 ± 9,52, što znači da su odabiri ispitanika bili značajno lošiji u usporedbi sa skupinom s PMED-om (ΣΔE*ab = 47,62 ± 9,88, p = 0,033). Odabiri u kontrolnoj skupini bili su značajno bolji u usporedbi sa svim skupinama s poremećajem kolornoga vida (kontrola – PMED, p = 0,031; kontrola – PSTD, p <0,0001; kontrola – DMED, p <0,0001; kontrola – DSTD, p < 0,0001), osim u usporedbi sa skupinom s DMID-om (p = 0,082). Usporedbe između skupina s deuteranopijom nisu se značajno razlikovale (DMID – DMED, p = 0,352; DMID – DSTD, p = 0,323; DMED – DSTD, p = 1,000). Zaključak: Sudionici s jakom protanopijom lošije su sparivali uzorke boja u odnosu prema sudionicima sa srednjom protanopijom.Objective: To evaluate the influence of the extent of color-vision deficiency on visual shade-matching ability. Materials and methods: Six groups were investigated: the control group (N = 68), the protan medium deficiency (PMED) group (N = 5), the protan strong deficiency (PSTD) group (N = 5), the deutan mild deficiency (DMID) group (N = 5), the deutan medium deficiency (DMED) group (N = 5) and the deutan strong deficiency (DSTD) group (N = 8). The color vision of the participants was evaluated monocularly using the Hardy-Rand-Rittler (HRR) test and on an HMC Anomaloskop MR (Rayleigh test). The final exam on a Toothguide Training Box consisted of 15 lightness–chroma–hue tasks. The color difference (ΔE* ab) and the shade-matching score (ΣΔE* ab) were computed. The means and the standard deviations for the ΣΔE* ab were calculated. An independent t-test was used for statistical analyses of the data and a comparison of means (α = .05) for protan groups and a one-way analysis of variance (ANOVA) and a post-hoc Bonferroni test (α = .05) for deutan groups. Results: The PSTD group had a mean ΣΔE* ab of 63.38 ± 9.52, which means their elections were significantly worse in comparison to the PMED group (ΣΔE* ab = 47.62 ± 9.88, p = 0.033). The selections of the control group were significantly better in comparison to all groups with color-vision deficiency (control – PMED, p = 0.031; control – PSTD, p < 0.0001; control – DMED, p < 0.0001; control – DSTD, p < 0.0001), except in comparison with DMID group (p = 0.082). The comparisons between deutan groups were not significantly different (DMID – DMED, p = 0.352; DMID – DSTD, p = 0.323; DMED – DSTD, p = 1.000). Conclusion: Participants with strong protan color-vision deficiency are worse at shade matching than participants with medium protan color-vision deficiency

Minimally invasive prosthodontics using the concept of prosthetically guided orthodontics

Objective: This case report aims to present how digital technology can be employed to plan the orthodontic movement of teeth into their final positions for prosthodontic rehabilitation. An interdisciplinary approach to treatment planning and the result of prosthodontic treatment involves the cooperation of an orthodontist and a prosthodontist. When planned to achieve optimal results for a minimally invasive and functional prosthodontic treatment, orthodontic pretreatment provides superior esthetic results and favorable long-term success. Clinical Considerations: The orthodontic movements of the teeth were planned so that the prosthodontist could reconstruct an optimally functional and esthetic occlusion while preserving the hard dental tissues. The orthodontic pretreatment minimized the need to prepare the teeth, avoiding any mucogingival surgery to improve the gingival architecture. Conclusions: In complex clinical cases, it is essential to evaluate the advantages of an orthodontic pretreatment before starting a prosthodontic treatment. This pretreatment can help preserve dental tissues, reduce or eliminate the need for surgical intervention, and achieve long-term stability and esthetic results. Clinical Significance: This case clearly shows the benefits of orthodontic pretreatment for prosthodontic outcomes. With modern digital tools, such an orthodontic pretreatment should become standard clinical practice when planning a complex clinical case

Differences between 3-D printed and traditionally milled CoCr dental alloy from casted block in oral environment

The aim of this study was to compare corrosion resistance and ion release in CoCr dental alloys with identical chemical compositions produced using different technologies (SLM – selective laser melting and milling from cast blocks) and heat treatment (SLM parts only). The corrosion properties were tested in artificial saliva, artificial saliva with fluoride ions, and artificial saliva with added lactic acid to simulate inflammations. The study included electrochemical tests, microstructural investigation and ion release tests in the three different environments for a total of 42 days. The best performance of CoCr as a result of potentiodynamic polarization was observed in the artificial saliva with added lactic acid, which is in contradiction with the highest ion release measured from all the materials tested and electrochemical impedance spectroscopy that showed a deterioration of the passive layer in an acidic environment. Microstructural investigation revealed that different phases precipitated by heat treatment trigger increased release of Mo and W ions. The printing method does not raise critically ion release from CoCr alloy, while the state of the surface greatly impacts the extent of the ion release. This study demonstrates the importance of an interdisciplinary approach to the study of corrosion and biocompatibility in dental alloys

Primerjava korozijskih lastnosti CoCrMo dentalnih zlitin v umetni slini

CoCrMo alloys are known for their biocompatible properties, which, together with their favorable mechanical properties, mean they can be efficiently used in dentistry. With the development of selective laser melting for the fabrication of 3D-printed ob - jects, interest in the corrosion properties of this alloy has risen in the field of prosthodontics. In the study, CoCrMoW dental al - loys were studied in artificial saliva at body temperature, i.e., 37 °C. Different forms of CoCrMoW alloy were selected: a refer - ence sample, i.e., original material as received from the supplier, a cast sample acquired from an ordinary procedure in a dental laboratory, and two 3D-printed samples made from CoCrMoW powder using the selective laser melting (SLM) method. Electro - chemical, spectroscopic and hardness measurements were conducted. It was shown that the reference and cast samples have similar microstructural and electrochemical properties, while the electrochemical properties of the 3D-printed samples differ, most probably due to the effect of the higher micro porosity and chemical composition of the alloys.CoCrMo-zlitine so znane po svojih biokompatibilnih lastnostih, ki jih zaradi ugodnih mehanskih lastnosti vse pogosteje uporabljamo v zobozdravstvu. Z razvojem selektivnega laserskega taljenja (SLT) se je zanimanje za izdelavo 3D tiskanih predmetov in preučevanje korozijskih lastnosti teh zlitin povečalo tudi v stomatološki protetiki. V študiji je bila preučevana CoCrMoW-zlitina v umetni slini pri telesni temperaturi 37 °C. Izbrane so bile različne oblike zlitin CoCrMoW: originalni referenčni vzorec dostavljen od dobavitelja, kovinski ulitek, pridobljen z ustaljenim postopkom v zobotehničnem laboratoriju in dva 3D vzorca iz prahu CoCrMoW, ki sta bila izdelana z uporabo metode selektivnega laserskega taljenja. Izvedene so bile elektrokemijske in metalografske preiskave z merjenjem trdote. Ugotovljeno je bilo, da imata referenčni in ulit material podobne mikrostrukturne in elektrokemijske lastnosti, medtem ko imajo vzorci 3D tiska različne elektrokemijske lastnosti, najverjetneje zaradi učinka večje mikro poroznosti in kemijske sestave zlitin

Position on the follow-up of patients after a bout of COVID-19 pneumonia

Pljučnica je najpogostejši vzrok za težji potek okužbe z virusom SARS-CoV-2 in s hospitalizacijo. Potek covidne pljučnice je lahko različeninfiltrati, vidni na rentgenski sliki, se lahko resorbirajo spontano, včasih pa je potrebno zdravljenje s sistem-skimi glukokortikoidi. Ob odpustu iz bolnišnice zdravljenje običajno še ni končano, zato je Združenje pulmologov Slovenije v želji po enotnem obravnavanju bolnikov s covidno pljučnico izdelalo mnenje za obravnavo in sledenje bolnikov po od-pustu iz bolnišnice. Zavedamo se, da ob novi bolezni ne gre za dokončno priporočilo, saj bodo nova spoznanja o covidni pljučnici zanesljivo zahtevala obnavljanje priporočil.Pneumonia is the most common complication of SARS-CoV-2 infection. Covid 19 - pneumonia is a serious illness and can lead to respiratory failure. Pulmonary infiltrates often resorb spontaneouslyhowever, sometimes treatment with systemic glucocorticoids is required. Upon discharge from the hospital, treatment is usually not yet completed. The Slovenian Respiratory society made suggestions for the treatment and follow-up of patients with covid 19 pneumonia after discharge from hospital. We are aware that with new findings we will need to update these recommendations
