administered with a response rate of 90.4%. The health
care workers were 331 between the ages of 18years to
64years. There were 200(60.4%) females and
131(39.6%) males (ratio 3:2). Less than half (41.7%) of
the respondents rated their knowledge on avulsion as
About half of the respondents 156(47.1%) reported that
primary tooth should be replaced into the socket. The
