Abstract only (at the time of collection of papers). However as the study lacked a negative control in the clinical trial design methodology it was excluded from the present review 13 Sauro et al.

Du et al. [27 ] No mention of randomisation and allocation concealment methods 18 Patsouri et al. [28 ] Abstract only 19 Surve et al. [29 ] Abstract only (at the time of collection of papers). However the study investigated the combination of an In-office application with or without a OTC desensitizing toothpaste following periodontal treatment and was therefore considered irrelevant for the present review 20 Yu et al. [30 ] Publication in Chinese (Abstract in English) 21 Milleman et al. [31 ] In-office agent (professionally applied polishing paste) and not as an OTC desensitizing toothpaste 22 Narongdej et al. [32 ] Novamin used as in-office agent 23 Banerjee et al. [33 ] Study duration ≤10 days 24 Tai et al. [37 ] Investigated the antigingivitis effect of Novamin on the gingival tissues (desensitizing toothpaste per se ) and therefore the study was considered irrelevant to this review 25 Acharya et al. [34 ] Excluded as the publication date was after December 31st and lacked a negative control in the clinical trial design methodology 26 Ananthakrishna et al. [35 ] Excluded as the publication date was after December 31st and lacked a negative control in the clinical trial design methodology 27 Neuhaus et al. [36 ] Excluded as the publication date was after December 31st and evaluated an In-office agent (professionally applied polishing paste) 28 Salian et al. [38 ] The negative control group contained fluoride whereas the test group (Novamin) did not 29 Sharma et al. [39 ] The negative control group contained fluoride whereas the test group (Novamin) did not 30 West et al. [40 ] The dentine specimens were placed in intraoral appliances worn by patients to establish an in situ effect of Novamin 31 Rajesh et al. [41 ] One further study was excluded due to the lack of description on the composition of the control randomization
