In-vitro Comparative Evaluation of Cariostatic Potential And Marginal Microleakage Of Commonly-Used Glass-Ionomer Restorative Materials as Interim Therapeutic Restorations.

Introduction: Glass ionomer cements (GIC) can ideally serve many restorative purposes in paediatric dentistry as it has advantages of chemical adhesion to tooth structure, as well as fluoride release and uptake into hard tissues.

Aims: To compare four commercially available conventional GIC based on the amount of fluoride release, marginal integrity and ability to increase microhardness of underlying artificial dentinal caries via remineralization.

Methods and Material: Standardized cavities were prepared on the buccal surface of 60 extracted sound premolars and artificial caries were induced onto the dentinal floor. Specimens randomized into four groups of fifteen teeth and restored with Fuji VII®, Riva Protect®, Riva Self Cure® and Fuji IX GP® Extra respectively. Measurement of fluoride release was done for 60 days. Subsequently, similar restorations prepared on lingual surface for microleakage test according to standard protocols.Dentin underlying buccal restorations were subjected to microhardness test while lingual restorations were evaluated for marginal microleakage.

Results: One-way ANOVA statistical analysis revealed significant difference was found in the amount of f luoride release between materials on all days of measurement (p<0.05). Riva Protect® released the highest amount of fluoride, followed by Fuji VII®, Riva Self Cure® and Fuji IX GP® Extra. Wilcoxon signed-rank test showed Riva Protect has theability to significantly improve the microhardness of artificial caries to the depth of 100 µm (p<0.05). There was a significant difference in the marginal sealing ability between materials with more microleakage seen with low-viscosity materials, analysed by Pearson’s Chi-Square test.

Conclusions: All materials possess cariostatic potential. However, Riva Protect® is suggested to exert the greatest cariostatic effects among the test materials

Background: Scaling and Root Planning (SRP) is the most commonly used procedure for treating gingivitis and periodontitis, which may be perceived as painful. The fear of pain during treatment has been identified as a major factor in preventing patients from seeking dental care. Pain control is considered to be an extremely important outcome measure for successful periodontal therapy.

Methods: Local application of Eutectic Mixture of Local Anaesthetic agent (EMLA) having higher concentration of local anaesthetic agent, considered as an effective way to reduce pain.

Results: The mean Visual Analogue Scale (VAS) when EMLA cream was used was lower compared to when EMLA cream was not used. The mean Verbal Rating Scale (VRS) was also lower when EMLA cream was applied.

Conclusion: The results of the present study warrant the use of EMLA in routine practice.

The author has been involved in the placement of thousands of dental implants of all types and has particular expertise in managing “salvage” or multiply operated patients who have had failed implants placed by other providers. The author also has expertise in the surgical management of temporomandibular joint disorders and complex infections of the head and neck region. The author has appointments at several well-known academic institutions. T he use of dental implants to replace missing teeth and in fact replace a patient’s entire dentition has become more commonplace over the past several years. One only has to turn on the television to notice that there are multiple facilities offering “teeth-in-a-day” or cheap implants, to replace ones missing dentition. These commercials, although alluring, can be very confusing for prospective patients and may lead to inadequate research being done not only into the procedure, but also into the clinician performing the procedure. Dental implants are safely placed by multiple specialties within the realm of dentistry and good outcomes are not specifically dependent on one’s specialty training but more contingent upon actual clinical experience.

In the 1980s, the work of Professors Bräne mark and Schroeder led to the introduction of a new surgical technique: implantology. In the beginning, the position of the implant depended mainly on the available bone volume. Successful treatment was based solely on osteo integration. In a few years, the reliability of this therapy has allowed the treatment from single tooth replacement to full-archrestoration, thus paving the way for an additional requirement: an aesthetic integration. Consequently, the position of the implant had to coincide with the future prosthesis. We moved from an implant ology paradigm guided by bone anatomy to implant ology guided by prosthetic requirements.When it concerns a canine replacement, both fuctional and esthetic require mentsare considered. In fact, the replacement of a canine tooth by an implant will, in its neuro physiologic consequences, exchange a protection system based on the presence of periodontal membrane receptors with one that depends on an implant anky losed in bone that can transmit only feeble information to be filtered by sensitive superior ganglia.A bonded bridge on lateral in cisor and first premolar can be a temporary solution during peri-implant bone healing, it requires a reversible tooth preparation limited to enamel.
