Introduction: The resin infiltration technique, a minimally invasive method, involves the saturation, strengthening, and stabilization of demineralized enamel by a mixture of polymer resins without the need to use rotary tools or the risk of losing healthy tooth structures. Aim of the study: 1. To design and synthesize an experimental infiltrant with potential bacteriostatic properties. 2. To compare the depth of infiltration of the designed experimental preparation with the infiltrant available in the market using a scanning electron microscope. Material and Methods: Composition of the experimental infiltrant was established after analysis of 1H NMR spectra of the commercially available compounds that can penetrate pores of demineralized enamel. As the infiltrant should have bacteriostatic features by definition, an addition of 1% of monomer containing metronidazole was made. Thirty extracted human teeth were soaked in an acidic solution, which was to provide appropriate conditions for demineralization of enamel. Afterward, each tooth was divided along the coronal-root axis into two zones. One zone had experimental preparation applied to it (the test group), while the other had commercially available Icon (the control group). The teeth were dissected along the long axis and described above underwent initial observation with use of a Hitachi S-4200 scanning electron microscope. Results: It was found that all samples contained only oxygen and carbon, regardless of the concentration of additions introduced into them. The occurrence of carbon is partially because it is a component of the preparation in question and partially because of sputtering of the sample with it. Hydrogen is also a component of the preparation, as a result of its phase composition; however, it cannot be detected by the EDS method. Conclusions: 1. SEM, in combination with X-ray microanalysis, does not allow one to explicitly assess the depth of penetration of infiltration preparations into enamel. 2. In order to assess the depth of penetration of infiltration preparations with use of X-ray microanalysis, it is recommended to introduce a contrast agent that is approved for use in dental materials, such as ytterbium III fluoride.

WSTĘP: Strach przed wizytą stomatologiczną jest poważnym problemem zarówno u dzieci, jak i u pacjentów dorosłych. Często staje się on przyczyną unikania wizyt, co może skutkować pogorszeniem nie tylko zdrowia jamy ustnej, lecz także całego organizmu. Istnieje wiele metod mających na celu zrelaksowanie i uspokojenie pacjenta przed samą wizytą oraz w jej trakcie. Wykorzystanie wirtualnej rzeczywistości stanowi jedną z nich. MATERIAŁ I METODY: Badanie pilotażowe przeprowadzono w grupie 100 dorosłych pacjentów, podczas gdy oczekiwali na wizytę stomatologiczną w poczekalni. Ankietowani wypełniali dobrowolny kwestionariusz wielokrotnego wyboru składający się z czterech pytań. WYNIKI: Wyniki pokazują, że najczęściej wybieranymi odpowiedziami były projekcja krajobrazów (40%) oraz interaktywny spacer, np. po plaży, lub trekking w górach (35%). Nie zaobserwowano różnic w zależności od płci. Zarówno mężczyźni, jak i kobiety najczęściej wybierali projekcję krajobrazów. Zdecydowana większość ankietowanych (87%) była skłonna skorzystać z dystrakcji z wykorzystaniem wirtualnej rzeczywistości podczas wizyty stomatologicznej. Pozostałe 13% pacjentów nie chciało w ogóle korzystać z wirtualnej rzeczywistości, niezależnie od proponowanego materiału audiowizualnego. WNIOSKI: Większość pacjentów była optymistycznie nastawiona do skorzystania z wirtualnej rzeczywistości podczas wizyty stomatologicznej. Najczęściej wybierane odpowiedzi były związane ze spokojnymi oraz relaksującymi materiałami niż z grami czy quizami. Badanie wskazuje, że pacjenci stomatologiczni są skłonni korzystać z nowoczesnych technologii w walce z dentofobią.

INTRODUCTION: Anxiety preceding dental appointment is a common problem among both children and adult patients. It is frequently the reason of avoiding visits what often results in poor oral health and deterioration of general well-being. There is a number of methods regarding patients’ relaxation as well prior the appointment as amid one, virtual reality among them. MATERIAL AND METHODS: The study was carried out among 100 adult dental patients while they waited for their appointment in the waiting room. Interviewees completed the multiple-choice, uncompelled questionnaire containing four questions. RESULTS: The results show that the most frequently chosen answer was projection of landscapes (40%) or an interactive journey like beach walk or mountain trekking (35%). No differences were observed between men and woman, in both groups projection of landscapes was the most common answer. The vast majority of interviewees (87%) was willing to try virtual reality during dental treatment while the remaining 13% did not want to experience virtual reality at all. CONCLUSIONS: Most of the participants were eager to try virtual reality amid dental appointment and they rather chose calm and relaxing contend instead of interactive quizzes or games. It is promising that dental patients are willing to be ready to try out innovative technologies in the fight against dental anxiety.
