Tooth color: effects on judgments of attractiveness and age.

Tooth whitening has become a very popular procedure. Advertisements for whitening products imply that whiter teeth are more attractive than yellower teeth. We tested this idea empirically by manipulating the tooth color of pictures of male and female targets. Participants' ratings of attractiveness were not influenced by tooth color. Exp. 2 yielded a negative correlation between attractiveness and age ratings: targets judged to be older were rated as less attractive. Unless whiter teeth help in some other way, e.g., improved self-esteem or confidence, it seems that tooth whitening procedures or products are not associated with increased attractiveness to others.

Clinical evaluation of a new 10% carbamide peroxide tooth-whitening agent.

NUPRO Gold Tooth Whitening System was evaluated for efficacy according to the proposed ADA guidelines for acceptance. Sixty participants with discolored anterior teeth participated in a 14-day, double-blind, clinical trial. The participants were matched for age, gender, and oral health status and were given either a placebo gel without the active agent or the NUPRO Gold active gel, which they wore in a custom-fabricated mouth guard for home use. The shade of each participant's maxillary anterior teeth was evaluated using a value-oriented Vita Lumin Vacuum Shade Guide before the study. The same shade guide was used to determine shade changes. Time of use of the agent and potential side effects, such as tooth and gingival hypersensitivity and tissue irritation, were assessed at all recall examinations and were recorded by participants in daily diaries. The average shade change for the placebo users was less than one shade. The average shade change for the NUPRO Gold users was 6.96 shades. Tooth hypersensitivity varied from none to severe. Tissue irritation was minimal. The results of these evaluations indicate that NUPRO Gold is effective as a tooth-whitening system, when administered properly under the supervision of a dentist, with commonly reported side effects of transient tooth sensitivity and minimal gingival sensitivity. Little or no change in tissue health was noted. This study was supported by Dentsply Preventive Care (York, Pennsylvania).

Enamel staining and hypoplasia due to multiple causes in a Nigerian adolescent: report of a case.

The aim of this report is to discuss the effects of childhood drug ingestion and metabolic disturbances of ill health in childhood on the coloration, structure and therefore the aesthetics of permanent dentition. To illustrate this, the report presents a case of a 15 year old Nigerian girl with combined tetracycline staining and chronological enamel hypoplastic defects on her teeth. The relationship between the clinical appearance of her teeth and her childhood medical and drug history are analysed. The various treatment modalities available for the management of the dental anomalies are discussed along with the rationale for the treatment given. Strategies for the prevention of these conditions are emphasised.

Efficacy of two dentifrices on removal of natural extrinsic stain.

PURPOSE: To evaluate the 6-week effect on natural extrinsic dental stain from the use of a dentifrice containing 10% aluminum oxide, 1500 ppm sodium monofluorophosphate in a precipitated calcium carbonate (PCC) base or a second dentifrice containing 0.5% calcium peroxide (CP), 1500 ppm sodium monofluorophosphate in a PCC base compared to a fluoride placebo dentifrice without stain removal ingredients. MATERIALS AND METHODS: A total of 94 subjects were entered in the study, and stratified into three balanced groups according to their baseline mean Lobene Stain Index scores. The three groups were randomly assigned to use one of the two test dentifrices or the placebo dentifrice. The three groups were well balanced with regard to their mean baseline stain index scores, gender and tobacco habits. Subjects were instructed to brush their teeth twice daily (morning and evening) for 1 minute with their assigned dentifrice and a commercially available soft bristled toothbrush. Extrinsic dental stain examinations, which included mean stain area and mean stain intensity, were conducted at baseline and 6 weeks. Examinations were conducted by the same dental examiner (F.A.) on the subjects at each examination. RESULTS: After 6 weeks' use of their assigned products, those subjects in the aluminum oxide/PCC dentifrice group and those subjects in the CP/PCC dentifrice group demonstrated statistically significant improvements, as compared to the fluoride placebo dentifrice group without stain removal ingredients.

The current status of vital tooth whitening techniques.

Tooth whitening of vital teeth continues to have a major impact on the practice of dentistry. The growing public interest in having whiter, brighter teeth is clearly evident in the advertisements from toothpaste manufacturers on "whitening" formulations of their products and by the number of individuals seeking whitening procedures from their dentists. In addition, new over-the-counter whitening products continue to emerge in a marketplace that cannot seem to get teeth white enough, bright enough, fast enough. What new products and procedures have evolved over the past decade to whiten teeth? Are they better, safer, faster, and more effective now? Are dentists meeting public demand for whiter teeth and is this quest having a positive or negative impact on the practice of dentistry or the patient's dental health? I posed these questions to a group of experts on whitening procedures to get their opinions and recommendations.

A six-week clinical efficacy study of a tooth whitening tartar control dentifrice for the removal of extrinsic tooth stain.

The objective of this double-blind clinical study was to investigate the tooth whitening efficacy of a new commercially available calculus-inhibiting dentifrice (Colgate Tartar Control Plus Whitening Fluoride dentifrice) containing tetra-sodium pyrophosphate, sodium tripolyphosphate, and PVM/MA copolymer in a 0.243% sodium fluoride/silica base (test dentifrice), compared to a commercially available, non-tooth whitening dentifrice containing 0.243% sodium fluoride in a silica base (control dentifrice). Following a baseline examination for, extrinsic tooth stain, qualifying adult male and female subjects from the Manchester, United Kingdom area were randomized into two treatment groups which were balanced for gender, age and level of extrinsic tooth stain. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice using a soft-bristled toothbrush. Examinations for extrinsic tooth stain were repeated after six weeks' use of the study dentifrices. Seventy-nine(79) subjects complied with the protocol and completed the entire study. At the six-week examination, subjects assigned to the test dentifrice treatment group exhibited statistically significant reductions of over 40% with respect to both extrinsic tooth stain area and extrinsic tooth stain intensity relative to those subjects assigned to the control dentifrice treatment group.

A six-week clinical efficacy study of a new dentifrice for the removal of extrinsic tooth stain.

The objective of this double-blind clinical study was to investigate the tooth whitening efficacy of a new dentifrice (Colgate Tartar Control Plus Whitening Fluoride Toothpaste) for the removal of extrinsic tooth stain, through a comparison with two commercially available dentifrices, Aquafresh Whitening Toothpaste with Fluoride, and Crest Regular Fluoride Toothpaste. Following a baseline examination for extrinsic tooth stain area and intensity, qualifying adult male and female subjects from the Mississauga, Ontario, Canada area were randomized into three treatment groups which were balanced for age, gender, and level of extrinsic tooth stain. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice using a soft-bristled toothbrush. Examinations for extrinsic tooth stain were repeated after six weeks' use of the study dentifrices. One hundred twenty-two (122) subjects complied with the protocol and completed the entire study. At the six-week examination, subjects assigned to the Colgate Tartar Control Plus Whitening treatment group and subjects assigned to the Aquafresh Whitening treatment group exhibited statistically lower levels (p < 0.0001) of extrinsic tooth stain area and intensity than did those subjects assigned to the Crest Regular Fluoride treatment group. Further, subjects assigned to the Colgate Tartar Control Plus Whitening treatment group exhibited significantly lower levels of extrinsic tooth stain area and intensity than did those assigned to the Aquafresh Whitening treatment group (p < 0.0001).

A six-week clinical efficacy study of three commercially available dentifrices for the removal of extrinsic tooth stain.

The objective of this double-blind clinical study was to compare the extrinsic tooth stain removal efficacy of three commercially available dentifrices: Colgate Platinum Whitening Toothpaste with Fluoride, Aquafresh Advanced Whitening Toothpaste with Fluoride, and Crest Regular Fluoride Toothpaste. Following a baseline examination for extrinsic tooth stain, qualifying adult male and female subjects from the Toronto, Ontario, Canada are were randomized into three treatment groups which were balanced for age, gender, tobacco habits, and level of extrinsic tooth stain using the Lobene Stain Index. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice using a soft-bristled toothbrush. Examinations for extrinsic tooth stain were repeated after six weeks' use of the study dentifrices. One-hundred forty-nine (149) subjects complied with the protocol and completed the entire study. At the six-week examination, subjects assigned to the Colgate Platinum treatment group exhibited statistically significant reductions (p < 0.05) from baseline level with respect to extrinsic tooth stain area (49.4% reduction) and extrinsic tooth stain intensity (52.4% reduction). Statistically significant reductions (p < 0.05) for both extrinsic tooth stain parameters were also exhibited by the subjects assigned to the Aquafresh Whitening treatment group (14.0% reduction for area, 15.5% reduction for intensity). Both tooth whitening treatments provided statistically significantly greater reductions (p < 0.05) in extrinsic tooth stain than did the Crest Regular Fluoride dentifrice, which exhibited a small increase in the extrinsic tooth stain parameters over the course of the study. Additionally, the Colgate Platinum dentifrice provided statistically significantly (p < 0.05) greater removal of extrinsic tooth stain over the course of this six-week study than did the Aquafresh Whitening dentifrice. Thus, the results of the double-blind clinical study support the conclusion that the two tooth whitening dentifrices, Colgate Platinum and Aquafresh Whitening, provide significantly greater (p < 0.05) removal of extrinsic tooth stain than does Crest Regular Fluoride, a sodium fluoride/silica dentifrice. Further, the results of the study support the conclusion that Colgate Platinum dentifrice provides a greater (p < 0.05) level of extrinsic tooth stain removal efficacy than does Aquafresh Whitening dentifrice.

A six-week clinical efficacy study of four commercially available dentifrices for the removal of extrinsic tooth stain.

The objective of this double-blind clinical study was to compare the efficacy for extrinsic tooth stain removal of four commercially available dentifrices: Colgate Tartar Control with Baking Soda & Peroxide Fluoride Toothpaste; Aquafresh Advanced Whitening Toothpaste with Fluoride; Rembrandt Tartar Control Low Abrasion Fluoride Whitening Toothpaste; and Crest Regular Fluoride Toothpaste. Following a baseline examination for extrinsic tooth stain on the anterior six mandibular and maxillary teeth, qualifying adult male and female subjects from the Philadelphia, Pennsylvania area were randomized into four treatment groups which were balanced for age, gender, tobacco habits, and level of extrinsic tooth stain. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice using a soft-bristled toothbrush. Examinations for extrinsic tooth stain were repeated after six weeks' use of the study dentifrices. One hundred eighty (180) subjects complied with the protocol, and completed the entire study. At the six-week examination, subjects assigned to the Colgate Tartar Control with Baking Soda & Peroxide Fluoride Toothpaste treatment group exhibited statistically lower levels of extrinsic tooth stain area and extrinsic tooth stain intensity than did those subjects assigned to the Crest Regular Fluoride treatment group. Subjects assigned to the Aquafresh Advanced Whitening treatment group exhibited significantly lower levels of extrinsic tooth stain area than did those assigned the Crest Regular Fluoride group. No other significant differences among the four study dentifrices were noted. Thus, the results of this double-blind clinical study support the conclusion that Colgate Tartar Control with Baking Soda & Peroxide Fluoride Toothpaste provides significantly greater control of extrinsic tooth stain than does Crest Regular Fluoride, a sodium fluoride/silica dentifrice.
