Purpose: To compare the effectiveness in reducing plaque and gingivitis of two fluoride toothpastes containing baking soda (35% and 20%) with a fluoride toothpaste control.
Methods: 319 subjects, who met entry criteria, participated in this single-center, three-cell, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed at baseline, and after 6 weeks, 3 and 6 months.
Purpose: To compare the effectiveness in reducing plaque and gingivitis of a fluoride toothpaste with 20% baking soda and a fluoride toothpaste control.
Methods: 159 subjects, who met the entry criteria, participated in this single-center, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed after 4, 8, and 12 weeks use of the assigned test or control toothpaste.
Objectives: This randomized, prospective clinical trial was conducted to determine the safety and effectiveness of a new whitening dentifrice formulation in comparison to that of both a negative and a positive control dentifrice.
Methods: Seventy-nine qualifying subjects were randomly assigned to either the new whitening dentifrice (Arm & Hammer® Truly Radiant™ Clean & Fresh Toothpaste), a positive control whitening dentifrice (Crest® 3-D White® Radiant Mint Toothpaste), or a negative control regular dentifrice (Colgate® Cavity Protection Toothpaste). The subjects brushed with their assigned dentifrice for two minutes, twice daily, for five days.
Objectives: The purpose of this study was to determine the plaque removal effectiveness of a new powered toothbrush and compare it to that of a manual brush.
Methods: This examiner-blind, randomized study used a cross-over design. Sixty-two (62) qualifying subjects were randomly assigned either to the powered brush (Arm & Hammer Spinbrush™ Truly Radiant™ Clean & Fresh Battery-Powered Toothbrush), or a standard manual toothbrush (ADA Standard Manual Toothbrush) and instructed to brush at home with a standard fluoride toothpaste twice daily for two minutes during a one-week familiarization period.
Objectives: The purpose of this study was to determine the safety and plaque-reducing effectiveness of a newly designed manual toothbrush compared to that of a leading marketed toothbrush and a reference standard manual toothbrush control.
Methods: This examiner-blind, randomized, single-use study used a cross-over design. Sixty-eight qualifying male and female subjects were randomly assigned either an Arm & Hammer™ Truly Radiant™ Deep Clean manual toothbrush (TR), a Colgate® Extra Clean manual toothbrush (C), or an ADA reference standard manual toothbrush (SM) according to one of three computer-generated sequences.
Context: The prevalence of sensitive skin among the general population in industrialized countries is reported to be over 50%. Sensitive skin subjects often report significant reactions to contact with cosmetics, soaps and other consumer products.
Objective: This paper describes the overall skin compatibility and mildness program for a newly developed, lightly fragranced, colorant free laundry product (i.
Objective: This randomized, controlled clinical trial was conducted to assess the extrinsic stain reduction achieved by brushing with a whitening dentifrice and powered toothbrush, and to determine whether the addition of a whitening booster paste to this regimen would enhance its stain reducing effectiveness.
Methods: Sixty qualifying subjects were randomly assigned either to Regimen One, a whitening dentifrice (Arm & Hammer Truly Radiant [TR] toothpaste] and powered toothbrush (Arm & Hammer Truly Radiant [TR] Extra Whitening Spinbrush); Regimen Two, the dentifrice and powered toothbrush with the addition of a whitening booster; or Regimen Three, a negative control (Colgate Cavity Protection toothpaste and an ADA standard manual brush). They were instructed in the use of their assigned products and then brushed unsupervised at home for two minutes, twice daily, for 14 days.
Objective: This study was conducted to evaluate the effectiveness of Arm & Hammer (A&H) Truly Radiant Rejuvenating toothpaste in removing extrinsic tooth stain compared to that of a conventional fluoride/silica-containing dentifrice.
Methods: This was a randomized, examiner-blind, parallel-design study with two groups of subjects who brushed unsupervised with their assigned dentifrice for two minutes, twice daily, for five days. Extrinsic stain was measured on the labial surfaces of the eight incisor teeth by the Modified Lobene Stain Index (MLSI) at baseline and following five days of product use.
Objective: This randomized controlled clinical trial was conducted to determine the effectiveness and safety of a new whitening dentifrice.
Methods: One hundred eighty-two qualifying subjects were randomly assigned to either a whitening dentifrice group (Arm & Hammer Truly Radiant Toothpaste), a negative control dentifrice group (Colgate Cavity Protection Toothpaste), or a positive control dentifrice group (Crest 3-D White Radiant Mint Toothpaste) and were instructed to brush twice daily with their assigned dentifrice for six weeks. Extrinsic tooth stain was assessed using a Modified Lobene Stain Index (MLSI) and tooth shade was assessed using the VITA Classic Shade Guide at baseline and after five days and two, four, and six weeks of dentifrice use.
Objective: The purpose of this study was to determine the plaque-reducing effectiveness of two new powered toothbrushes and compare them to a manual toothbrush control.
Methods: This examiner-blind, randomized study used a crossover design. Sixty-five qualifying male and female subjects were randomly assigned one of the two test powered brushes (Spinbrush Truly Radiant Deep Clean [TRDC] or Spinbrush Truly Radiant Extra Whitening [TREW], Church & Dwight Co.
Objective: The purpose of this study was to determine the plaque removal effectiveness of a new children's powered toothbrush and compare it to that of a manual brush.
Methods: This examiner-blind, randomized study used a cross-over design. One-hundred and five qualifying male and female subjects (52 ages 8-12 and 53 ages 13-17) were randomly assigned either the powered brush (Spinbrush GLOBRUSH) or a manual toothbrush (Oral-B Indicator 30 Compact Soft Toothbrush) and instructed to brush at home with a standard fluoride toothpaste twice daily for two minutes during a one-week familiarization period.
Objective: The primary purpose of this randomized, controlled, six-week clinical trial was to determine the effectiveness and safety of a new whitening dentifrice in removing extrinsic tooth stain and whitening teeth. An additional two-week exploratory study was conducted to determine whether the whitening or stain-prevention activity of the dentifrice would persist following cessation of use.
Methods: In the first study (Phase I), one-hundred and forty-six qualifying subjects were randomly assigned to either a sodium bicarbonate whitening dentifrice group (Arm & Hammer Advance White Extreme Whitening Baking Soda and Peroxide Toothpaste) or a silica-based negative control dentifrice group, and brushed twice daily with their assigned dentifrice for six weeks.
Objective: The purpose of this study was to validate and calibrate an in vitro test method for screening the performance of peroxide-containing toothpastes against actual clinical whitening performance. An additional objective was to estimate the whitening performance of a new peroxide-additive gel using the in vitro methodology.
Methods: A one-month longitudinal clinical study was performed to provide a benchmark for the in vivo intrinsic whitening performance of a peroxide-containing fluoride toothpaste.
Objective: To evaluate and compare the effectiveness in reducing plaque of a fluoride dentifrice containing baking soda and a non-baking soda fluoride dentifrice containing an antimicrobial (triclosan/copolymer) system after a single brushing and over a four-week period of daily brushing.
Methods: A total of 207 subjects completed this randomized, blinded, parallel-group clinical study. Twenty-four hour plaque buildup was scored at baseline and after two and four weeks of twice-daily use of the products.
Objective: An earlier clinical study demonstrated that brushing with a commercial Arm & Hammer dentifrice containing baking soda physically removed significantly more plaque than brushing with either of two commercial dentifrices which did not contain baking soda. However, little has been done to confirm these results and to compare baking soda-containing dentifrices with more recently commercialized non-baking soda dentifrice formulations. The objective of this study was to compare commercial dentifrices containing 20% to 65% baking soda and commercial dentifrices without baking soda in enhancing plaque removal efficacy of tooth brushing.
View Article and Find Full Text PDFNew dual-phase fluoride toothpastes that contain soluble calcium, phosphate, and baking soda have recently been introduced into the market. These toothpastes are designed to fill in small surface defects in tooth enamel and thereby enhance tooth esthetics such as gloss. This two-part study was designed to assess these superficial mineralizing effects from using one of these products compared with an experimental calcium-containing, bicarbonate-free formulation and a conventional fluoride toothpaste using an intraoral model.
