Definition of scoping review
⢠Exploratory projects that
systematically map the
literature available on a topic,
identifying key concepts,
theories, sources of evidence
and gaps in the research -
Colquhoun (2014)
What do you understand by the word âsystematicallyâ?
7. Dr. D. Y. Patil Dental College and Hospital, Pune Department of Public Health Dentistry
Dr. S. A. Rizwan, M.D.,Scoping reviews: An introduction
Birth of scoping reviews â 1/2
⢠Since early 2000s
⢠25 different types of knowledge
synthesis
⢠Most common member - systematic
review
⢠Terminology
⢠Mapping studies, systematic scoping
studies, scoping studies
⢠Donât confuse with evidence mapping
or evidence gap maps

Scope of a scoping review
⢠Precursor to systematic review
⢠Identify types of evidence available in a
field
⢠Analyze knowledge gaps
⢠Clarify key concepts/definitions
⢠Examine how is research conducted on a
certain topic
⢠Nature and diversity of knowledge in the
field

ScR is different from SR â 1/2
⢠Broad objective
⢠PCC instead of PICO(ST)
⢠Less restrictive inclusion criteria, not
restricted to one type of study design
⢠No synthesis of results (meta-analysis)
⢠No risk of bias assessment
⢠Limited in informing clinical practice or
policy making
What is the PICO(ST) format?

articulate the rationale for the
review and provide clear
explanations for PCC

Discussion
⢠Results should be discussed in the
context of current literature,
practice and policy
⢠Scoping reviews are subject to the
limitations
⢠As no rating of the quality of
evidence is provided, implications
for practice or policy cannot be
graded
31. Dr. D. Y. Patil Dental College and Hospital, Pune Department of Public Health Dentistry
Dr. S. A. Rizwan, M.D.,Scoping reviews: An introduction
Conclusions and recommendations
⢠Overall conclusion based on the
results
⢠Clear, specific implications for
future research
⢠Future conduct of systematic
reviews
⢠May not be possible to develop
implications for practice/policy
Regardless of the considered irrigation solution, most
existing cases corroborate the occurrence of some
damage to the mechanical properties of endodontically
treated teeth.
The findings from this scoping review show that aesthetic
perception is not directly related to acceptability and
satisfaction of patients and parents but related to a lower
professional's acceptance. Therefore, it is recommended
that professionals should be encouraged to offer this
treatment to patients and their parents, better advising
them about the facilities and effectiveness of the Silver
Diamine Fluoride technique.
