Authors, year	Sample (participants)	Age (years)	Interventions	Controls	Supervision time	Method of assessment	Results
Acharya et al., 2013	20	18–65	Dentifrice containing CSPS	Dentifrice containing potassium nitrate.	Baseline, 2, 4 and 8 weeks	EVA	CSPS showcased a higher reduction in DH in comparison to potassium nitrate.
Bansal and Mahajan, 2017	45	20–50	Dentifrice containing 5% NovaMin	Dentifrice 8% (Arginine) Herbal dentifrice	Baseline, 2 and 4 weeks	EVA	Toothpaste may be an effective and inexpensive option in the treatment of DH.
Bevilacqua et al., 2016	30	18–60	Biosilicate	Fluorine gel and nanostructured desensitizer	Baseline; 1, 2 and 12 weeks	EVA	Regardless of the assessment period, there was no statistical difference between the treatments in pain reduction. Both were effective in reducing DH.
Du et al., 2008	71	21–56	Dentifrice containing 5% NovaMin	Dentifrice containing SrCl2	Baseline, 2 and 6 weeks	EVA	NovaMin® more effective in reducing DH compared to control.
Gopinath et al., 2015	36	18–60	Dentifrice containing CSPS	Nano-HAP dentifrice	Baseline and 4 weeks	EVA	Both groups reduced sensitivity.
Hall et al., 2017	135	18–60	Dentifrice containing 5% CSPS	Colgate Pro Alivium (8% Arginine) Colgate Triple Protection	Baseline, 1, 2, 4, 6 and 11 weeks	EVA	Dentrifices containing 5% CSPS was as effective as positive control.
Narongdej et al., 2010	60	26–70	Novamin power in dentifrice containing NovaMin	Placebo powder in dentifrice. Placebo powder with dental cream containing NovaMin®	Baseline, 1, 2 and 4 weeks	EVA	The use of NovaMin® powder and toothpaste containing NovaMin is more effective than the other groups.
Neuhaus et al., 2013	151	18–70	Toothpaste with 15% NovaMin with 2.7% sodium fluoride; toothpaste with 15% NovaMin without fluoride.	Paste without NovaMin® and without fluorine	Baseline and 4 weeks	Yeaple Probe	The CSPS was able to reduce the DH and this effect was independent of the presence of fluorine.
Pradeep and Sharma, 2010	110	20–60	Dentifrice containing CSPS	Placebo dentifrice containing NaNO3 and KNO3	Baseline, 2 and 6 weeks	EVA	The CSPS group was significantly better at reducing DH.
Rajesh et al., 2012	30	18–65	Dentifrice containing 5% NovaMin	Placebo	Baseline, 2, 6 and 8 weeks	EVA	Novamin® significantly reduced DH when compared to a placebo dentifrice.
Salian et al., 2010	30	20–50	Dentifrice containing 5% NovaMin Dentifrice with 5% potassium nitrate	Non-desensitizing dentifrice	Baseline, 2 and 4 weeks	EVA	The dentrifice containing 5% NovaMin provides rapid and significantly greater relief from DH compared to the other groups.
Samuel et al., 2015	56	18–65	Dentifrice containing 5% NovaMin	ProArgin™ (8% arginine) Gluma®	Baseline, 2 and 4 weeks	EVA	The three groups showed significant reductions in DH.
Sharma et al., 2010	120	20–50	Dentrifice containing 7,5% calcium phosphate sodium (NovaMin)	Dentifrice with 5% potassium nitrate; dentifrice with 0,4% tin fluoride	Baseline, 2, 4 and 12 weeks	EVA	NovaMin® provided significant improvements in the early stages compared to the other groups.
Shashirekha and Jena, 2015	45	18–50	5% NovaMin	8% arginine, 15% n-hp	Baseline, 1 and 4 weeks	EVA	Toothpaste containing 15% n-HA was more effective in reducing DH followed by 8% arginine and 5% novamin toothpastes.
Tirapelli et al., 2011	160	18–70	1% biosilicate gel Biosilicate® in distilled water at 10%	Sensi Kill® Dentrifice Sensodyne®	Baseline and 4 weeks	EVA	Biosilicate, gel or mixed with distilled water is efficient in the treatment of DH.
