Lepore 2011.

Methods Trial design: parallel (2 arms)
Location: Columbia University Medical Center, USA
Number of centres: 1
Study duration: recruitment and follow‐up dates not reported. Participants followed‐up at 2 months
Participants Participants: 69 paediatric‐child patients between ages 1 and 6 years
Inclusion criteria: not reported
Exclusion criteria: not reported
Age (years): between ages 1 and 6 years, with the majority (90%) being 2 years to 5 years (mean age of 3 years)
Gender: not reported
Number randomised: 69 (intervention group: 37; control group: 32)
Number evaluated: 69 (intervention group: 37; control group: 32)
Interventions Intervention: dental prophylaxis and topical fluoride application, routine oral health instructions (as given to the control group). In addition a personalized oral health action plan which consisted of an assessment of the patient's current caries risk and a list of suggestions on how to improve that status. The parent and dentist together chose 1 particular suggestion they felt was achievable
Control: dental prophylaxis and topical fluoride application, routine, verbally dispensed oral hygiene and diet instructions targeting the specific needs of the patient
Prophylaxis provided: both groups received a dental prophylaxis and topical fluoride varnish application
Member of dental team delivering intervention: dentist
Frequency of intervention: intervention group: 1 initial visit with OHA; control group: 1 initial visit with OHA
Intensity of intervention (length of time): intervention group: not reported; control group: not reported
Setting: secondary care
Disease level: caries risk
Outcomes Data collected included DMFS, gingival health and plaque scores. During the first visit, the parents were questioned regarding the oral hygiene and diet behaviour of the child in order to fulfil the 6 survey topics (frequency of toothbrushing with a fluoridated dentifrice, parent‐assisted toothbrushing, bottle use, sippy cup use, frequency of juice consumption and frequency of between‐meal snacking). Data for the reported behaviour was categorized as low, moderate or high caries risk and assigned a numerical value of 0, 1 or 2, respectively
Notes Funding: not reported
Sample size calculation: not reported
Adverse effects: not reported
Declarations/conflicts of interest: not reported
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Quote: "divided randomly into control and intervention groups"
Comment: insufficient information on random sequence generation
Allocation concealment (selection bias) Unclear risk Comment: insufficient information on allocation concealment
Blinding of participants and personnel (performance bias) 
 All outcomes Unclear risk Quotes: "32 patients in the control group received routine, verbally dispensed oral hygiene and diet instructions targeting the specific needs of the patient. In addition to the routine oral health instructions given to the control group, the 37 patients in the intervention group received a personalized oral health action plan" and "The parent and dentist together chose 1 particular suggestion they felt was achievable"
Comment: blinding of participants was not possible; it is unclear the influence this would have on the risk of bias for this domain
Blinding of outcome assessment (detection bias) 
 All outcomes Unclear risk Quotes: "Finally, since this was a single blind study, upon follow‐up examination, experimenter bias has to be considered and results may be skewed" and "...This discrepancy could probably be accounted for considering the other 3 major limitations of this study: the sample size, observation time and potential examiner bias"
Comment: unclear on who was blinded to group allocation
Incomplete outcome data (attrition bias) 
 All outcomes Unclear risk Comment: no dropouts reported, however difference in group allocation (37 versus 32). The authors may not have reported any possible dropouts, only reporting those available at the end of the study
Selective reporting (reporting bias) Low risk Comment: all outcomes in methods section were reported. Unclear what plaque index and gingival health index were used but unlikely to influence outcome
Other bias Unclear risk Unclear baseline comparability and ITT not completed
Method states DMFS to be scored but within abstract and results table dmft is reported
