UV Irradiation as a Disinfection Method to Reduce Covid-19 Cross-Contamination in Dentistry: A Scoping Review

Abstract

The new coronavirus (COVID-19) quickly became a pandemic. Its transmission occurs mainly by direct contact, but its indirect transmission cannot be neglected. The dental office becomes a place of a high risk of contamination, mainly through aerosols and particles decanted on the surface. Concern about biosafety has become imminent and essential supplies of personal protection have become scarce. Several methods of disinfecting protective materials, the environment, and surfaces are being studied to reduce cross-infection, such as ultraviolet (UV) light. Our objective was to conduct a review of the recent literature in order to elucidate the use of UV technology in disinfecting environments and surfaces to reduce crosscontamination of COVID-19 in the health area, and how it can be used in the dental area. The PubMed database was used, and the articles were selected according to their relevance between 2018 and 2020. It is concluded that decontamination in environments and surfaces is effective, while the use of UV in PPE seems to be possible but deserves attention. It is suggested to carry out further studies aimed at disinfection by UV light in the dental area so that it can be used safely and effectively.

  Authored by  Chaza Kouchaji, Introduction ECC experience is defined as the presence of one or more decayed (noncavitated or cavitated lesions), missing (due to caries) or filled tooth surfaces in any primary tooth in a child aged 71 months or younger [1]. ECC is the most commonly observed chronic disease in children [2]. ECC continues to be pandemic disease according to World Health Organization. The prevalence generally ranges from 27%-48%, with more than 76% reported from the Middle East [3]. While in Syria the burden of ECC amongst Syrian children aged 3-5 years was dmft value of 4.25 ± 4.2 per child [4]. Main risk factors that contribute to the formation of ECC were microbiological, environmental and dietary factors [5]. The clinical appearance of the teeth in S-ECC in a child 2, 3, or 4 years of age is typical and follows a definite pattern. There is early carious involvement of the maxillary anterior teeth, the maxillary and mandibular first primary molars, and sometim...

Oral Pyogenic Granuloma: Case Report of an Atypical Presentation

Abstract “Granulomas seem to be a defensive mechanism that triggers the body to “wall off” foreign invaders such as bacteria or fungi to keep them from spreading” [1]. Pyogenic granuloma is a relatively common benign skin growth that consists of vascular nodules of proliferating capillaries [2]. They grow rapidly and often occur following a minor injury or trauma, most likely as a vascular or fibrous response to injury or irritant [2]. Ultimately, the etiology of pyogenic granuloma is still unknown. Oral pyogenic granuloma is most commonly found on the gingiva, followed by the lips, tongue, buccal mucosa, and hard palate [3]. It often presents as a red, smooth, or lobulated exophytic lesion which can be pedunculated or sessile and often bleeds on provocation [4]. A microscopic evaluation of pyogenic granuloma often reveals that the lesion is fully or partially covered by parakeratotic or non-keratinized stratified squamous epithelium. The majority of the lesion is formed by a lobulated...

Hepatitis B Virus among Dental Clinic Workers and the Risk Factors Contributing for its Infection

Abstract Objectives:  Dental clinic workers (DCWs) in Yemen have an additional risk of getting infected with HBV from their workplace and till now they are not routinely vaccinated against HBV infection. This study aimed to estimate prevalence of hepatitis B virus infection and associated risk factors among DCW in selected dental clinics in Sana’a city. Study design:  Data were acquired from a cross sectional survey conducted among DCWs in 2014 at the Faculty of Dentistry, Sana’a University, in Sana’a city. A proportionate to size random sample was drawn per DCW category. A structured questionnaire was used to collect data about socio-demographic characteristics and risk factors. ELISA was used to test sera for HBV markers. Result:  The study included 246 dentists and 263 dental assistants, the sero-prevalence of current hepatitis B virus infection was 6.1%; while prevalence of life time exposure to hepatitis B virus infection was 18%. Prevalence of needle stick injuries,...
