The St. Regis environmental health issue: assessment of dental defects.

A descriptive epidemiologic study was undertaken to determine the nature, extent, and severity of defects of the dentition alleged to be fluorosis in Native American children. An examination of 520 Native American children living on the St. Regis Reservation, and 248 non-Native American children living in adjacent areas, disclosed a much higher prevalence of generalized pigmentation of the dentition in the former (114, 22%) as compared with the latter group (13, 5.2%). The pattern of enamel pigmentation, opacity, and hypoplasia observed was not typical of fluorosis. After careful consideration of various etiologic factors, use of the antibiotic tetracycline was determined to be the probable causative agent in 112 (21.5%) cases, of which 73 (14%) were classified as esthetically objectionable according to the tetracycline severity index devised. Confirmation of incorporation of the drug into the teeth was made possible in selected cases by histopathologic analysis of extracted teeth.

A review of the literature on use of chlorhexidine in dentistry.

In addition to its plaque-inhibiting effect, chlorhexidine possesses other properties beneficial for use in dentistry. These effects are outlined, and specific recommendations are given regarding chlorhexidine's use by general practitioners. The side effects of long-term use, such as staining, and the availability of chlorhexidine also are discussed.

The use of a direct bonded microfilled composite resin veneer.

This technique creates a direct bonded microfilled composite resin veneer that replicates the complex color distribution and surface texture of the natural tooth structure. Duplicating the complexity of natural tooth color can be repeated by recording the different layers of color used in their sequence of placement.

Bleaching teeth: new materials--new role.

Today, bleaching alone can be effective in restoring appearance to teeth stained from various causes. Moreover, bleaching can be combined with other restorative treatment to produce results not otherwise possible. Bleaching requires careful diagnosis and techniques but offers a relatively simple, safe, and successful way to significantly improve appearance. In the future, bleaching will be a routine, conservative treatment option.

Calcium hydroxide in the treatment of external root resorption.

A case is presented in which calcium hydroxide was used in endodontic treatment of external root resorption in a tooth with a necrotic pulp, during active orthodontic movement. A calcified deposit formed, filling a defect, and the tooth was subsequently obturated with gutta-percha. Thus, both types of therapy--endodontic and orthodontic--were performed simultaneously.

Dental esthetic satisfaction in adults.

This study determined the influence of teeth, mouth, and face on self-image and personal esthetic satisfaction in adults. A random sample of 125 patients completed a five-item questionnaire about personal esthetic satisfaction and oral self-image. As a group, general dental variables were stronger predictors of esthetic satisfaction than orthodontic variables (P less than .01). Discrepancies between clinical findings and patterns of self-perception and satisfaction suggest the dentist and patient should plan together for esthetic dental treatment.

Effect of toothbrushing with 0.4% stannous fluoride and 0.22% sodium fluoride gel on gingivitis for 18 months.

This study determined the effect of brushing with 0.4% stannous fluoride (SnF2) or 0.22% sodium fluoride (NaF) on clinical and microbial parameters associated with gingivitis. The study included three groups of 281 subjects. Subjects in all three groups were instructed to brush twice daily with an ADA-accepted fluoride dentifrice, rinse their mouths with water, and subsequently brush with 0.4% SnF2, 0.22% NaF, or a fluoridefree placebo gel. More stain was detected in the SnF2 group than in the other two groups at all periods except at baseline. However, no differences were observed in gingivitis, bleeding, or mean proportions of microbial forms in the SnF2 or NaF groups when compared with the placebo group at 18 months. Results indicate that 0.4% SnF2, or 0.22% NaF is no more effective than a placebo in reducing gingivitis.

Interpretation of base-metal dentinal radiopacities: survey results.

A survey was conducted to determine the familiarity with base metal dentinal radiopacity. The results show that although 91% of the respondents had observed this phenomenon, only 6% could correctly identify its cause. Despite the general misunderstanding concerning its cause, 48% of the respondents considered this radiopacity when making a diagnosis and providing treatment. To limit confusion, a standard term is suggested so this feature can be more consistently identified and properly considered in making diagnoses and in formulating treatment plans.

What about whiteners? Safety concerns explored.

The quest for a brighter, more attractive smile has fueled rapid growth in the marketplace for tooth whiteners. With names like BriteSmile, Denta-Lite, Ultra Lite and Whiter Teeth, these products are grabbing the attention of looks-conscious consumers. More than a dozen whiteners have flooded the market recently, most of them available by dentist prescription, a few being sold directly to consumers over the counter. There's no doubt these products work as whiteners, at least on mild to moderate stains. The looming questions is this: are they safe? This article explores that safety question and seeks to provide practicing dentists with some perspective on the issue. We don't pretend to have the definitive answer. As always, it's up to you, doctor, to decide what's best for your patients. It's up to us to provide information that helps you make those crucial decisions. That's our goal.

Intensive swimming: can it affect your patients' smiles?

Athletes who swim intensively, such as those who swim laps more than six hours a week, may develop unusual yellowish brown or dark brown stains on their teeth. The authors hypothesize that long-term contact of the teeth with swimming pool water, as well as the mixture of oral fluids with swimming pool water, leads to the formation of these deposits. The authors report two cases of development of such stains.

Assessing tooth color change after repeated bleaching in vitro with a 10 percent carbamide peroxide gel.

The aim of this study was to obtain information about tooth color changes in 25 extracted human incisors resulting from repeated bleaching with a 10 percent carbamide peroxide gel. Using a colorimeter, the author recorded color changes in the L*a*b* color space after each bleaching period. The observed tooth color change was found to be dependent on the bleaching time, the specific bleached section and the initial color. The most significant total tooth color change was observed in the incisal section of the crown, followed by the middle and the cervical sections.

A comparison of two prophylaxis angles: disposable and autoclavable.

In a clinical trial, the authors evaluated the effectiveness of stain, plaque and debris removal, as well as patient and hygienist acceptance, of the disposable prophylaxis angle vs. the autoclavable prophylaxis angle. Thirty patients received a dental prophylaxis by hygienists for up to 45 minutes. A clinician performed blinded pre- and post-prophylaxis evaluations for stain, plaque and debris. A matched pairs t-test determined significant differences (P < .05) between groups. Significantly less stain, plaque and debris remained following use of the disposable vs. the autoclavable angle.

Nightguard vital bleaching: current concepts and research.

Nightguard vital bleaching, or NGVB, which involves the use of a 10 percent carbamide peroxide in a custom-fitted mouthguard, has been used with much success since its introduction in 1989. Normal bleaching treatment time is one to two weeks, although times may be extended to months for difficult stains. When used in a professionally supervised manner, nightguard vital bleaching is as safe as any other routinely used dental treatment.
