[Observation of osteoclasts on the root surface during human deciduous teeth resorption].

OBJECTIVE: To observe osteoclasts on the resorbing surface of human deciduous teeth. METHODS: After fixing the collected deciduous teeth, we prepared the tooth slices without decalcification, treated them with HE and TRAP dyestuff, and observed the osteoclasts under light and scanning electron microscope. RESULTS: There were large quantity of various forms of overlapping and huge osteoclasts with many nuclei and silk-like protuberances on the resorbing surface of deciduous teeth. The multinucleated osteoclasts align on the surface of coarse dentin. CONCLUSION: On the resorbing surface of human deciduous teeth there are large amount of osteoclasts which can be used as a source of studying human osteoclast.

Achieving optimal aesthetics using contemporary porcelain materials: a case report.

While the selection of an appropriate material contributes to restorative success, a thorough treatment plan with enhanced clinician/technician communication is required to ensure an appropriate and aesthetic result. A concise understanding of the patient's existing condition, desires, and expectations is critical to ensure restorative success. This case presentation demonstrates the clinical and laboratory protocols for the development of predictable, functional, and aesthetic porcelain restorations in treating severely compromised maxillary anterior dentition.

Using the golden proportion in aesthetic treatment: a case report.

Many dental patients are unhappy with their smile but believe a beautiful smile is outside their budget. The first step is to listen to the patient in order to understand what his or her primary concerns are. The second step is to examine carefully and analyze the case to develop a treatment plan that will fulfill as much as possible of the patient's desires within the context of his or her constraints (financial or otherwise). Also, remember that dentistry doesn't end when the last veneer is placed or the last bill is paid. The final step is to maintain a strong relationship with your patients to ensure good oral hygiene and restorations that are as long-lasting as they are beautiful.

[Comparison of the clinical efficacy of self-etching bond system and composite resin in repair of dental defects].

PURPOSE: To compare the efficacy of self-etching bond system and composite resin in repair of dental defects. METHODS: 201 teeth were randomly divided into two groups. 101 teeth in the experimental group were treated with CLEARFIL self-etching bond and AP-X to repair dental defects, while 100 teeth in the control group were treated with Durafill bond and Charisma. 201 teeth were followed up for 1,3,6 months, respectively. The date was analyzed by Chi square test. RESULTS: The result showed that the successful effective rate of the experimental group (98%) was significantly higher than that of the control group (90%, P<0.05) statistically. CONCLUSIONS: Using of self-etching bond system and composite resin to repair dental defects has indicated perfect retention and marginal sealing, which is worthy of wide clinical application.

The use of a rotational-path design for a mandibular removable partial denture.

The lack of display of anterior metal clasps is a primary advantage of the A-P rotational-path mandibular RPD design. A disadvantage of this design is that it relies on rigidmetal guiding plates for anterior retention and stability. Loss of retention may require procedures much more involved than the simple adjustment of conventional RPD clasps. Proper adherence to design, survey, fabrication, and adjustment procedures described by the authors should result in an esthetically pleasing and well-retained tooth-supported removable prosthesis. This article recommends the A-P rotational-path mandibular RPD as a treatment the clinician can use to restore multiple missing anterior teeth and satisfy a patient's financial, esthetic, and functional requirements.

Evidence-based approach for treatment planning options for the extensively damaged dentition.

Restoring the extensively damaged dentition has always been a difficult decision-making process for the dental practitioner. Decisions to restore these teeth were primarily based on the fact that "fixed" teeth are typically better functionally than "removable" teeth and better esthetically than "no" teeth. Prior to dental implants, restoring missing teeth and extensively damaged teeth utilizing traditional therapy such as crown lengthening, root hemisection/amputation, endodontic therapy, apical surgery, post and cores and splinting were the options available to our patients. These teeth typically required the expertise of additional specialist, however their prognosis and success rates were typically guarded at best. Presently, dental implant success rates have been clearly identified and documented in the literature which now questions the survivability and success rates of the traditional mode of therapy for extensively damaged teeth. This paper will attempt to review the dental literature for various traditional modes of therapy for restoring the extensively damaged to provide a consensus of their survivability to help the practitioner to present options and prognosis for their patients.

Five-year follow-up with Procera all-ceramic crowns.

OBJECTIVE: The purpose of this study was to evaluate the clinical performance of Procera AllCeram crowns placed over a 5-year period at three different private dental practices. METHOD AND MATERIALS: Two hundred five Procera AllCeram crowns (50 anterior and 155 posterior) were evaluated in a prospective study from a minimum of 6 months to a maximum of 60 months, with a mean of 23.52 months. RESULTS: A restoration was considered to be a failure when it impaired esthetic quality or function, thus necessitating remake of the crown. The survival rate was determined with the use of the Kaplan-Meier survival rate, which gave an overall survival rate of 96.7% (100% for the anterior crowns and 95.15% for the posterior crowns). CONCLUSION: The Procera AllCeram system seems to have a good prognosis for the posterior teeth and an excellent one for the anterior teeth.

Porcelain laminate veneers: 6- to 12-year clinical evaluation--a retrospective study.

The purpose of this study was to retrospectively evaluate the clinical performance of laminate veneers placed in the anterior segments of the dental arches over a 12-year period at two different private dental practices. Forty-six patients were restored with 182 porcelain laminate veneers. The veneers were studied for a mean observation time of 5.69 years. Color match, porcelain surface, marginal discoloration, and marginal integrity were clinically examined following modified CDA/Ryge criteria. On the basis of the criteria used, most of the veneers rated A. Risk of fracture was determined with a Kaplan-Meier survival analysis. Probability of survival of the 182 veneers was 94.4% at 12 years, with a low clinical failure rate (approximately 5.6%). Porcelain veneers must be bonded with a correct adhesive technique to reach this successful survival rate.
