Work-related ocular events among Nigerian dental surgeons

Clement C Azodo, Ejike B Ezeja

Daily clinical activities in dental operatory expose dental surgeons to varied forms of ocular events. The purpose of the study was to determine the prevalence and pattern of ocular splashes and foreign bodies among dental surgeons in Nigeria. This questionnaire-based cross-sectional of dental surgeons in Southern Nigeria was conducted between September 2010 and August 2011. The information elicited were demography, experience and type of ocular event, implicated dental procedure and action taken. Of the 185 studied, 148 of them responded. Of these 148 respondents, 56 (37.8%) reported foreign body, 18 (12.2%) splash, 33 (22.3%) both foreign body and splash while 41 (27.7%) reported no ocular event. It therefore means that the overall prevalence of ocular events among the respondents was 107 (72.3%). The prevalence of ocular events was significantly associated with age (p = 0.014), years of practice (p = 0.033) and safety eye goggle use (p = 0.023). The main dental procedures implicated in the ocular events among the respondents were scaling 77 (72.0%), tooth/cavity preparation 17 (15.9%), polishing 11 (10.3%) and forcep tooth extraction 10 (9.3%). The major implicated aetiological agents in the ocular events were calculus 74 (69.2%), saliva 29 (27.1%), mixed blood & saliva 19 (17.8%), tooth particles 15 (14.0%) and blood 9 (8.4%). The predominant action taken by the respondents was to rinse the eye under running water 89 (83.2%). Ocular splash and foreign body events are high among dental surgeons in Nigeria. Age, years of practice and safety eye goggles wear were also found to be associated with ocular events. Eye safety awareness is therefore deemed a necessity for dental surgeon in Southern Nigeria.
