Predictors of non-carious loss of cervical tooth tissues.

This Predictor Variables study is designed to determine which one of 11 factors evaluated may be correlated to Non-carious Loss of Cervical Tooth Tissues (NLCTT) using subjects with and without NLCTT. The ultimate objective is to successfully predict the path toward risky behaviors and reduce the incidence of NLCTT.

A 24-month follow-up of flowable resin composite as an intermediate layer in non-carious cervical lesions.

This study compared the clinical performance of a microhybrid resin composite to lined Class V restorations or to those restorations without a flowable resin composite over a 24-month period. Nineteen patients with at least 2 pairs of equivalent cervical erosion/attrition/abfraction lesions, under occlusion, were enrolled in this study. A total of 74 restorations were placed, half for each group (Single-Bond + Filtek-Flow + Filtek Z250 or Single-Bond + Filtek Z250). According to the manufacturers' instructions, 2 calibrated operators placed all restorations. Two other independent examiners evaluated the restorations at baseline and after 24 months, according to the USPHS criteria and modified criteria for color match. The classic alpha score was divided into A1 for "not detectable" and A2 for "slightly discernible" filling. Statistical analysis was conducted using Fisher's exact test (alpha=0.05). For each group, 8 restorations were lost after 24 months (retention rate of 89.2%). All the restorations showed a trend toward dark yellowing after 24 months (color match A2).

Acupuncture and occlusal splint therapy in the treatment of craniomandibular disorders. II. A 1-year follow-up study.

Eighty patients, of whom 22 were men and 58 women, participated in a 1-year follow-up study. All participants in the study showed signs and symptoms of craniomandibular disorders (CMD) and had had pain for more than 6 months at treatment start. The patients were randomly assigned to either acupuncture or occlusal splint therapy. Those patients who did not respond to either of the treatment modes were offered various additional therapies. The result showed that 57% of the patients who received acupuncture and 68% of the patients treated with occlusal splint therapy benefited subjectively (p < 0.01) and clinically (p < 0.001) from the treatment over a 12-month period. No statistically significant difference was found between the two groups as to the assessment variables. Those patients who received various additional therapies after acupuncture and/or occlusal splint therapy responded favorably to additional treatment in only a few instances. The study showed that acupuncture gave positive results similar to those of occlusal splint therapy in patients with primarily myogenic CMD symptoms over a 1-year follow-up period.

Hypothyroidism and anemia related to fluoride in dairy cattle.

Blood and urine were collected from 72 cows in six dairy herds with varying severity of dental and bone fluorotic lesions. Urinary fluoride averaged 5.13 ppm and ranged from 1.04 to 15.7 ppm fluoride. Thyroxine and triiodothyronine in serum decreased with increasing urinary fluoride, eosinophils increased, and cholesterol tended to decrease. Cattle afflicted with fluorosis developed hypothyroidism, anemia, and eosinophilia of leukocytes. Bone ash averaged 2400 ppm fluoride in 22 specimens from eight herds (range 850 to 6935 ppm fluoride). Mineral supplements were the main sources of excess fluoride. Fluoride lesions were on some cows of all herds suggesting that fluoride may affect the health and performance of some cows in "normal" herds. Fluoride lesions were on young cattle and calves in fluorosis herds.

1-year clinical evaluation of Compoglass and Fuji II LC in cervical erosion/abfraction lesions.

PURPOSE: This study was undertaken to compare the clinical performance of a polyacid-modified resin-based composite and a resin-modified glass-ionomer restorative material over 1 year. MATERIALS AND METHODS: Thirty-four pairs of restorations of Compoglass (C) and Fuji II LC (F) were placed in 31 patients, with no patient receiving more than two pairs, and with materials assigned at random within the pairs. Caries-free cervical erosion/abfraction lesions of the facial surface were restored without tooth preparation according to manufacturers' instructions, except that tooth structure to be restored was etched with 37% phosphoric acid prior to placement of Compoglass. Restorations were clinically evaluated by two blinded examiners at baseline, 6 months, and 1 year, using modified Ryge/USPHS criteria. Restorations receiving a score of "Charlie" in either retention or secondary caries were classified as failed restorations. The incidence of failures was statistically analyzed as a pairwise comparison, using an exact binomial test. RESULTS: Thirty-one pairs of restorations were available for recall at 1 year. The percentage of Alfa scores for each material in each category were: Retention (C = 84%, F = 100%), Color match (C = 81%, F = 100%), Marginal discoloration (C = 78%, F = 97%), Secondary caries (C = 88%, F = 100%), Anatomic form (C = 92%, F = 100%), and Marginal adaptation (C = 26%, F = 46%). Except for the failed restorations, no other Charlie scores were assigned. A significant difference in the incidence of failed restorations was found between the materials (P = 0.01).

Evaluation of esthetic parameters of resin-modified glass-ionomer materials and a polyacid-modified resin composite in Class V cervical lesions.

OBJECTIVE: The purpose of this study was to compare the esthetics of 3 resin-modified glass-ionomer materials and 1 polyacid-modified resin composite to the esthetics of a conventional glass-ionomer control material. METHOD AND MATERIALS: One hundred eighty-seven Class V cervical restorations were observed clinically over 18 months. The esthetic index system that was used evaluated color match, translucency or opacity, and surface roughness. RESULTS: The tested materials behaved very dissimilarly and inconsistently. In general, the esthetic results of the resin-modified glass-ionomer materials and the polyacid-modified resin composite were far from optimal. The esthetic appearance of restorations seriously deteriorated during clinical service, mainly because of discoloration of margins, changes in translucency and opacity, and rapidly appearing roughness or dullness on the surface. Both the resin-modified glass-ionomer materials and the polyacid-modified resin composite evaluated in this study performed better esthetically than did the conventional glass-ionomer material. CONCLUSION: Indications for these combination materials are limited to areas where esthetics is not a primary concern but where their ease of application may guarantee a more durable functional result.

Recognition of bulimia nervosa in dental patients: implications for dental care providers.

Patients with bulimia nervosa commonly exhibit distinctive oral characteristics. Dental health providers should be able to recognize these signs and identify patients with this condition. Members of the dental health team then must intervene and assist in facilitating treatment of the eating disorder. Current knowledge about bulimia nervosa and its oral signs and preventive, interventive, and restorative strategies for dental health practitioners are presented.

Etiology and diagnosis of tooth wear: a literature review and presentation of selected cases.

PURPOSE: This article presents an overview of etiologies associated with tooth wear. MATERIALS AND METHODS: Specific types of wear based on clinical findings and patient history are described. RESULTS: The occurrence and pattern of tooth wear are related to cultural, dietary, occupational, and geographic factors. Examples of tooth wear related to these factors with regional specificity are presented. CONCLUSION: The dental practitioner should recognize the characteristic signs of tooth wear, as they may be the first to discuss the problem with the patient. Management should be based on accurate diagnosis.
