Q

Anatomy of a scientific paper

A

Scientific papers may be published on subjects of relevance to HCPs
Majority focused on ‘discovery; research, and therefore are generally pre-clinical
Clinically relevant data might be present (e.g. F release data, cytotoxicity, mechanical properties etc BUT
Most highly regarded scientific publications deal with experimental materials/ systems AND
Scientific papers based on commercial material data held in lower regard (and may not be as well-reviewed)
First page provides title, authors and affiliations, and usually a short abstract of the whole paper (that may include a graphical abstract)
Content sections may also start on page 1. Here the intro describes the background, context and rationale for research, and may conclude with an aim or hypothesis
Next is generally “Methods” or “Experimental” section
-meant to describe the experimental design and steps, including stats, in sufficient detail to repeat study
Next is “Results”
-provides data generated by experiments in previous section
Next is “Discussion”
-provides author’s considered interpretation of data generated by experiments
Followed by Conclusions

Q

Marketing materials

A

All leading manufacturers invest in publication of marketing materials (paper and online) to persuade dentists of their merits
while > sales is primary objective, marketing materials from reputable businesses may still be useful
They may signpost key publications including clinical (albeit favourable), and include useful info on correct use e.g. with step-bu-step guides to > likelihood of successful adoption
Unless referenced, not peer reviewed
Confidence substantially reduced
Are these measures clinically relevant? Is clinical data available?
