Dugotrajno noŔenje maski za lice kod stomatologa pogorŔava samoprijavljene simptome suhog oka tijekom pandemije bolesti COVID-19
Objectives: The aim of the study was to evaluate self-reported MADE during the COVID-19 pandemic in dental healthcare practitioners and identify their possible risk factors. Material and Methods: An anonymous questionnaire was sent to doctors of dental medicine in the time period from February 2022 to August 2022. The online questionnaire included demographic characteristics and clinical characteristics: presence and deterioration of DED symptoms while wearing the face mask, personal protective face equipment, use of contact lenses, history of eye surgery, current use of medica-tions, number of hours wearing face mask, and evaluation of subjective DED symptoms using modified Ocular Surface Disease Index (OSDI). Results: A total of 405 participants were included in the study and an overall prevalence of MADE was 29.1% (95% CI: 24.7 - 33.6). The participants who used masks more than 6 hours per day during the whole day reported a higher OSDI score (12.5 (IQR = 2.6 ā 29.2)) compared to the participants who used masks less than 6 hours/day (6.25 (IQR = 0 ā 22.92); Mann-Whitney U Test p = 0.066). Multivariable logistic regression revealed the following possible risk factors for self-reported MADE: age (older than 61 years) OR: 3.522 (95% CI 1.448 -8.563); p=0.05, and wearing the face mask more than 6 h at work OR: 1.779 (95% CI 1.017 ā 3.113); p=0.044. Conclusion: The prevalence of self-reported MADE among dental healthcare practitioners appears to be significant. The use of a face mask for a prolonged duration increases OSDI scores. MeSH Terms: face masks, dry eye, MADE, ocular discomfort, COVID-19, protective face equipment.Cilj: Željelo se procijeniti samoprijavljeni MADE kod stomatologa tijekom pandemije bolesti COVID-19 i identificirati moguÄe Äimbenike rizika. Materijal i metode: Anonimni upitnik poslan je doktorima dentalne medicine u razdoblju od veljaÄe 2022. do kolovoza iste godine. Postavljena pitanja obuhvaÄala su demografske i kliniÄke podatke: prisutnost i pogorÅ”anje simptoma DED-a tijekom noÅ”enja maske za lice, osobne zaÅ”titne opreme za lice, koriÅ”tenje kontaktnih leÄa, povijest operacija oka, trenutaÄnu upotrebu lijekova, broj sati noÅ”enja maske za lice i procjenu subjektivnih simptoma DED-a s pomoÄu modificiranog indeksa za bolesti oÄne povrÅ”ine (OSDI). Rezultati: U studiju je bilo ukljuÄeno ukupno 405 sudionika, a ukupna prevalencija MADE-a bila je 29,1 % (95 % CI: 24,7 ā 33,6). Sudionici koji su se koristili maskama viÅ”e od 6 sati na dan tijekom cijelog dana prijavili su viÅ”i OSDI rezultat (12,5 (IQR = 2,6 ā 29,2)) u usporedbi s onima koji su nosili maske kraÄe od 6 sati na dan (6,25 (IQR = 0 ā 22,92); Mann-Whitneyjev U test, p = 0,066) Multivarijabilna logistiÄka regresija otkrila je sljedeÄe moguÄe Äimbenike rizika za samoprijavljeni MADE: dob (stariji od 61 godine) OR:3,522 (95 % CI 1,448 ā 8,563); p = 0,05 i noÅ”enje maske za lice dulje od 6 sati na poslu OR: 1,779 (95 % CI 1,017 ā 3,113); p = 0,044. ZakljuÄak: Äini se da je prevalencija samoprijavljenog MADE-a meÄu stomatolozima znaÄajna. Dulje koriÅ”tenje maske za lice tijekom rada poveÄava OSDI rezultate
Current state of the art in 3D printing of metals in dental medicine
Napretkom tehnologije i digitalizacijom dentalne medicine razvile su se nove tehnike proizvodnje metalnih nadomjestaka i njihovih konstrukcijskih elemenata koje su dovele do unaprjeÄenja mnogo industrija. Aditivna tehnologija, odnosno 3D gradnja, svoju primjenu naÅ”la je i u dentalnoj medicini. Zbog svojih je prednosti poput obrade metala, oÄuvanja izvrsnih svojstava, brzine i
jednostavnosti proizvodnog postupka te konaÄno cijene, zamijenila analogne tehnike, ali i digitalne reduktivne metode. NajÄeÅ”Äe koriÅ”tene tehnike 3D gradnje metala u stomatologiji temeljene su na PBF-u, a to su DMLS, SLM i EBM. Nadalje, tehnikama 3D gradnje pojednostavila se obrada legura koje se, unatoÄ biokompatibilnosti i dobrim mehaniÄkim svojstvima, zbog složene izrade
analognim tehnikama nisu Äesto koristile. Razvojem tehnologije 3D gradnje poveÄala se izrada konstrukcijskih dijelova protetskih nadomjestaka od legura Co-Cr i titanija, koje su danas zlatni standard u dentalnoj medicini. Metali i njihove legure najÄeÅ”Äe se koriste u dentalnoj protetici i implantologiji za izradu metalnih osnova krunica, mostova, implantata i implantoloÅ”kih suprastruktura pa je i upotreba 3D gradnje metala najveÄa u tim granama dentalne medicine.Through advances in technology and digitalization of dental medicine, new techniques have developed for the production of metal-based dental appliances and their structural elements that have led to the progress of many industries. Additive technology, i.e. 3D printing, has found its application in dental medicine as well. Due to its advantages in terms of metal processing, the preservation of excellent properties, speed, simplicity of production and, finally, in terms of price, it replaced analogue techniques, as well as digital reductive methods. The most commonly used 3D metal printing techniques in dentistry are based on PBF, namely DMLS, SLM and EBM. Furthermore, 3D printing techniques have simplified the processing of alloys that, despite their biocompatibility and favourable mechanical properties, were seldom used due to complicated
analogue manufacturing techniques. The development of 3D printing technology has increased the production of structural elements for prosthetic dental appliances made from Co-Cr and titanium alloys, which are considered the current professional standard in dental medicine. Metals and their alloys are most often used in dental prosthodontics and implantology for the production of metal bases for crowns, bridges, implants and implantological superstructures. Therefore, the use of 3D metal printing is the most substantial in these fields of dental medicine
