Two-year clinical performance of a polyacid-modified resin composite and a resin-modified glass-ionomer restorative material.

This study compared the clinical performance of a polyacid-modified resin composite and a resin-modified glass-ionomer restorative material over two years. Thirty-four pairs of restorations of Compoglass and Fuji II LC were placed in caries-free cervical erosion/abfraction lesions without tooth preparation. Restorations were clinically evaluated at baseline, 6, 12, 18 and 24 months using modified Ryge/USPHS criteria. A significantly higher incidence of failed restorations was found with the polyacid-modified resin composite (p < 0.05).

Tooth-colored filling materials for the restoration of cervical lesions: a 24-month follow-up study.

The recently developed resin-modified glass ionomer cements and the polyacid-modified composites are promising alternatives to conventional materials for restoring cervical defects. This clinical study evaluated the clinical condition of cervical fillings 24 months following placement. The study subjects were 197 cervical restorations placed on incisors, canines and premolars in 37 patients for restoration of erosion/non-carious lesions (69 cases), primary carious lesions (57 cases) and the replacement of deficient restorations (71 cases). The teeth were randomly divided into four groups for restoration with either Tetric (composite, Group A: n = 36), Dyract (compomer, Group B: n = 79), Fuji II LC (resin-modified glass ionomer cement, Group C: n = 51) or Photac-Fil (resin-modified glass ionomer cement, Group D: n = 31). The evaluation was done single-blind at baseline, 8 and 24 months after the placement of the fillings, according to a modified USPHS rating scale. The assessment criteria were color stability, anatomical form, surface texture, marginal integrity, marginal discoloration and loss of filling. Statistical analysis was completed using Pearson chi-square and Fisher's exact test at a significance level of 5% (p < 0.05). After the 24-month period, the composite restorations showed superior results. The compomer fillings demonstrated conditions that were only slightly worse. A substantial number of the resin-modified glass-ionomer fillings were evaluated with bravo or even charlie scores in respect to at least one of the criteria assessed.

Women's oral health issues.

Hormonal fluctuations affect more than a woman's reproductive system. They have a surprisingly strong influence on the oral cavity. Puberty, menses, pregnancy, and menopause all influence women's oral health and the way in which a dentist should approach their treatment. This paper will review aspects of a woman's life when hormonal fluctuations may affect oral tissues.

[Adhesive techniques in the treatment of tooth wear due to bruxism].

Wear due to bruxism is not restricted to those surfaces of the tooth that are loaded by occlusion and articulation. Due to tooth flexure wedge-shaped lesions, so-called abfractions, may develop. In the treatment of wear caused by bruxism, direct composite restorations may play an important role. Composite resin can be used to cover exposed dentin and to restore the incisor and canine guidance. In combination with a nightguard, such a treatment may prevent further wear.

Eating disorders in women's oral health.

Eating disorders such as anorexia nervosa, bulimia nervosa, and binge-eating disorder are a serious concern in women's oral health and a clinical challenge to dental professionals. Each of these eating disorders presents with unique patterns of psychologic, medical, and dental characteristics. Appropriate dental treatment is based in the multidisciplinary facets of these conditions. The dental team should be mindful that individuals who suffer from these disorders may relapse into previous negative eating behaviors. The knowledgeable dental professional may be able to intercept these habits through regular recall intervals and thorough examination.

Presentation, diagnosis and initial management of patients referred to a hospital tooth wear clinic.

Information on presenting complaints, diagnosis and initial management strategy was recorded on a proforma for 114 consecutive patients referred to a hospital tooth wear clinic over a two-year period. Over twice as many male patients were referred as females. Twenty percent of patients had no presenting complaint and the others shared the common complaints concerning appearance, sensitivity and their deteriorating dentitions. The assessment of aetiology identified attrition as the most common cause of tooth wear in the subject group studied. About half the group were prescribed preventative treatment only and the other half were deemed to require restorative dental treatment.

The use of adhesive restorations in the management of localised anterior toothwear.

Toothwear appears to be increasingly common, particularly in the younger age groups, and will often require restorative intervention to provide satisfactory appearance and function. Well established conventional restorative techniques can be relatively complex and time-consuming and as a consequence may not be accessible for many patients. This paper, with the help of the literature, discusses the alternative application of a variety of adhesive materials and techniques used in the restoration of moderate to severe anterior toothwear.

[Evaluation clinical long-term curative effect and analysis of its influence factors after restoration of teeth with wedge-shaped defects].

OBJECTIVE: To evaluate the long-term curative effect clinically and analysis of its influence factors after restoration of teeth with wedge-shaped defects. METHODS: Seventy five cases of 509 teeth with various degrees of dental wedge-shaped defects were randomly divided into two groups--the group restored by Dyract Cement and the group restored by 3M-Vitremer. Evaluation was made with the modified USPHS evaluation criterion after restoration for 1,2,4 years respectively. RESULTS: The successful rate dropped down from 2 year successful rate 85.5% to 4-year 27.7%. The new wedge-shaped defects were presented at the cervical margin of the original restoration in 1.8% (2 years later) and 6.6% (4 years later). There were a lot of influence factors on long-term curative effect. The failure rate in the group with occlusal interference was significantly higher than that without occlusal interference. CONCLUSIONS: The clinical successful rates are affected by the value of occlusal force on the restored teeth and the physical properties of the restorative materials. It is suggested that the process of restoration of dental wedge-shaped defect should include obviating occlusal factors as well as to improve the properties of restorative materials.

One-year clinical performance of a resin-modified glass ionomer and a resin composite restorative material in unprepared Class V restorations.

This study evaluated the clinical performance and appearance of a resin-modified glass ionomer and a resin composite over one year. Thirty-seven pairs of restorations of Fuji II LC and Z250/Single Bond were placed in caries-free cervical erosion/abfraction lesions without tooth preparation. Restorations were clinically evaluated at baseline and 6 and 12 months, using modified Ryge/USPHS criteria. No significant difference (p>0.05) was observed in performance of both materials, although retention of the Z250 restorations was below the minimum specified in the ADA Acceptance Program for Dentin and Enamel Adhesives. Little difference in the restorations' appearance was observed.

One-year clinical performance of a self-etching adhesive in class V resin composites cured by two methods.

This study evaluated the clinical performance of a self-etching adhesive for resin composites over one year. Thirty pairs of restorations of Pertac II, using the adhesive Prompt L-Pop, were placed in caries-free cervical erosion/abfraction lesions without tooth preparation. One of each pair was cured using "soft-start" polymerization, while the other was polymerized with high-intensity halogen light. Restorations were clinically evaluated at baseline, six and 12 months using modified Ryge/USPHS criteria. Although no significant difference (p>0.05) was observed between the curing methods, adhesive performance was poor, with a 35% loss of restorations overall.
