Abstract

Objective: In this study, the carriage of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible Staphylococcus aureus (MSSA)(S. aureus) was investigated in preclinical and clinical student groups at the IYY University Faculty of Dentistry.
Methods: The present study was an in vivo study carried out between December 03 and 21, 2018 at the Dentistry Faculty of İstanbul Yeni Yüzyıl University. A total of 76 preclinical and 76 clinical students provided nasal swab samples for the study. Samples were obtained from the first one-third of the anterior nasal region of both nostrils and examined microbiologically. The study findings were statistically evaluated using a chi-square continuity test with (Yates) correction (P < .05).
Results: S. aureus was detected in 16 of 76 (21.1%) clinical students who treated patients, and 3 of the 76 (3.9%) preclinical students who did not treat patients. No MRSA colonization was found in any group. There was a statistically significant difference in the prevalence of S. aureus between the clinical students who had contact with patients and the preclinical students who did not provide care (P = .003, P < .05).
Conclusion: In this study, the frequency of S. aureus findings in the group of clinical students who cared for patients was statistically significant (P = .003, P < .05). This result indicates that infection control protocols should be followed more closely and that, in particular, the clinical students who care for patients should pay more attention to the established rules of hygiene.
Keywords: Dentistry, methicillin-resistant, Staphylococcus aureus.

ÖZ
Amaç: Bu çalışmada, Yeni Yüzyıl Üniversitesi Diş Hekimliği Fakültesi’ nde, hasta bakmayan 76 preklinik öğrencisi ile, hasta bakan 76 klinik öğrencisinin ön burun bölgesinden alınan sürüntü örneklerinde, metisiline dirençli Staphylococcus aureus (MRSA) ve Staphylococcus aureus (S. aureus) taşıyıcılığı araştırıldı.
Yöntemler: Çalışmamız, burun sürüntü örneği alınmasını kabul eden, hasta bakmayan 76 preklinik öğrencisi ile hasta bakan 76 klinik öğrencisi arasında yapıldı. Araştırmaya katılan öğrencilerin her iki burun deliğinin 1/3 ön burun bölgesinden sürüntü örnekleri alınarak mikrobiyolojik olarak incelendi. Çalışmada elde edilen bulgular, istatistiksel olarak Continuity (Yates) Düzeltmeli Ki-Kare Testi kullanılarak değerlendirildi (P < ,05).
Bulgular: Çalışmamızda hasta bakmayan 76 preklinik öğrencisinin 3’ünde S. aureus saptanırken (%3,9), hasta bakan 76 klinik öğrencisinin 16’ sında S. aureus saptandı (%21,1). MRSA kolonizasyonuna ise hiçbir grupta rastlanmadı. Hasta bakmayan preklinik öğrencileri ile hasta bakan klinik öğrencileri arasında S. aureus görülme oranları açısından istatistiksel olarak anlamlı farklılık saptandı (P = ,003; P < ,05).
Sonuç: Yaptığımız araştırmada, klinikte hasta bakan öğrenciler grubunda S. aureus oranı istatistiksel olarak anlamlı derecede yüksek bulundu (P = ,003; P < ,05). Bu sonuç, enfeksiyon kontrol protokollerine daha sıkı uyulması ve klinikte hasta bakan öğrencilerin, hijyen kurallarına daha fazla dikkat etmeleri gerektiğini göstermektedir.
