| Abstract | Cilj istraživanja:
Utvrditi stavove ispitanika o konvencionalnoj i digitalnoj tehnici otiskivanja te utvrditi koja je tehnika otiskivanja vremenski zahtjevnija.
Materijali i metode:
U istraživanju je sudjelovalo 34 studenata četvrte, pete i šeste godine studija Dentalne medicine Medicinskog fakulteta Sveučilišta u Splitu. Koristili smo dva upitnika - jedan iz perspektive pacijenta, drugi iz perspektive terapeuta, sastavljena od dva dijela - prije i nakon otiskivanja, kako bi utvrdili mišljenje studenata o metodama otiskivanja. Digitalni otisak uzimao se intraoralnim skenerom Sirona Primescan (Dentsply Sirona, Sirona Dental Systems Bensheim, Germany), a konvencionalni Orthotrace alginatom (Zhermack SpA, Badia Polesine, Italy) u metalnoj konfekcijskoj žlici. Vrijeme potrebno za otiskivanje se mjerilo dva puta za digitalni otisak, a za konvencionalni jednom.
Rezultati:
Saznali smo da je 62% studenata u potpunosti upoznato s konvencionalnom tehnikom otiskivanja, dok je samo 12% studenata u potpunosti upoznato s digitalnom tehnikom otiskivanja.
Prije otiskivanja, 70,6% studenata očekivalo je da će im digitalna tehnika otiskivanja biti jednostavnija za izvođenje, no nakon otiskivanja mišljenje se značajno promijenilo (41,2%) (s, p =0.0145, χ2-test).
Ispitanici su i prije i nakon otiskivanja smatrali da digitalna tehnika ne izaziva ni nagon na povraćanje, ni otežano disanje. Većina ispitanika (79%) prije otiskivanja smatra da je digitalna tehnika ugodna, ali nakon otiskivanja mišljenje se značajno pogorša (s, p=0.0034).
Smatrali su da konvencionalni otisak izaziva nagon na povraćanje, a nakon otiskivanja mišljenje se promijenilo (s, p=0.0329, Wilcoxonov test usklađenih parova). I prije i nakon otiskivanja mišljenja su da konvencionalna tehnika otiskivanja izaziva otežano disanje.
Digitalna tehnika otiskivanja zahtijeva manje vremena u usporedbi s konvencionalnom tehnikom otiskivanja na nižim godinama studija (s, 4.godina psken1vsklas=0.0031, psken2vsklas<0.0001, Fisherov test najmanje značajne razlike). Vrijeme potrebno za konvencionalnu tehniku otiskivanja lineralno opada s višom godinom studija (p=0.0109).
Zaključak:
I konvencionalna i digitalna tehnika otiskivanja su jednostavne za izvođenje, ali konvencionalna tehnika je jednostavnija u usporedbi s digitalnom.
Konvencionalna tehnika otiskivanja izaziva otežano disanje, ali je ugodnija nego što su ispitanici to smatrali prije otiskivanja, dok digitalna tehnika ne izaziva ni refleks na povraćanje ni otežano disanje, ali je neugodnija za pacijenta nego što se smatralo prije otiskivanja.
Studentima nižih godina studija potrebno je manje vremena za digitalnu tehniku otiskivanja, a studentima viših godina potrebno je manje vremena za konvencionalnu tehniku otiskivanja.
Vrijeme potrebno za digitalnu tehniku otiskivanja linearno pada s rastom godine studija.
Potrebno je uključiti digitalne tehnike otiskivanja u kurikulume studija Dentalne medicine. |
| Abstract (english) | Objective:
To determine participants’ opinions on the use of conventional and digital impression techniques and to determine which impression technique requires less time.
Materials and methods:
The study was conducted on 34 students in 4th-, 5th- and 6th-year of study of Dental medicine at the University of Split. We used two questionnaires - one was from the patient's perspective, while the other one was from the practitioner's perspective. Both questionnaires consisted of two parts - before and after impression-taking. The aim of questionnaires was to determine students' opinions on impression. Intraoral scanner Sirona Primescan (Dentsply Sirona, Sirona Dental Systems Bensheim, Germany) was used for digital impression and metal stock trays and Orthotrace alginat were used for conventional impression (Zhermack SpA, Badia Polesine, Italy). The digital impression was timed twice, and conventional once.
Results:
62% of participants were completely familiar with conventional technique while only 12% of participants were completely familiar with digital impression technique.
Before impression taking, 70,6% of students expected digital technique to be easier to perform, but afterwards opinions significantly changed (41,2%) (s, p =0.0145, χ2-test).
The participants, both before and after the impression taking, considered that digital technique causes neither the gag reflex nor breathing difficulties. Before impression taking, majority of participants (79%) believe digital technique to be completely or partially pleasing, but after impression taking opinions worsened significantly (s, p=0.0034).
Before impression taking, the participants considered that conventional impression causes the gag reflex, but afterwards opinions change significantly (s, p=0.0329, Wilcoxon matched-pairs signed-rank test). They thought, both before and after the impression taking, that conventional technique causes breathing difficulties.
Digital impression technique requires less time compared to the conventional impression technique when performed by lower- year students (s, 4th year pscan1vsclass=0.0031, pscan2vsclass<0.0001, uncorrected Fisher’s LSD test). The time required for the conventional impression decreases linearly with the higher year of study (p=0.0109).
Conclusions:
Both conventional and digital impression techniques are simple to perform, but conventional impression technique is easier compared to the digital technique.
Conventional technique causes breathing difficulties, but it is more pleasant than the participants assumed before the impression taking. Digital technique causes neither the gag reflex nor breathing difficulties, but it is not as pleasant as considered before the impression- taking.
Lower- year students require less time for the digital impression technique, and upper- year students require less time for the conventional technique.
Conventional impression time decreases significantly with upper-year students.
New digital techniques should be included in the dental schools’ curricula. |
