Abstract

Aim

To evaluate the existence of different esthetic smile criteria in a section of North Indian population.

Materials and methods

A total of 100 students from Manav Rachna International University were selected based on the inclusion criteria. Two photographs were taken (smiling face and smile) using Digital Single Lens Reflex camera. The statistical analyses used were descriptive statistical tests and Spearman correlation after the images were analyzed using Digimizer image analysis software for different esthetic smile criteria.

Results

The coincidence of the facial midline with the arch midline occurred in more than half of the students. Most of the subjects presented parallelism between the incisal plane and the interpupillary line. Mostly parallel or straight smiles were also most commonly observed and the gingival display and the amount of gingival display were relatively less observed.

Conclusion

There exists a relationship between facial midline, interpupillary line, smile arc, gingival display, and facial esthetics.

Clinical significance

This article describes the existence of different esthetic smile criteria in enhancing the facial esthetics for a pleasing smile.

Corrosion Resistance of indigenously Fabricated Dental Magnets for Application in Prosthodontics

[Year:2017] [Month:April-June] [Volume:7] [Number:2] [Pages:5] [Pages No:48 - 52]

Abstract

Aim

The aim of the study is to evaluate the corrosion resistance of the indigenously fabricated dental magnet.

Materials and methods

The Teflon-encased Neodymium-Iron-Boron (Nd–Fe–B) magnet was put to test to comply with the standardized conditions. The corrosion behavior was examined using the statistical immersion analysis according to the International Organization for Standardization (ISO) 10271:2001: “Dental metallic materials corrosion test methods.” In this method, the maximum ion release after 7 days was evaluated. The test specimen (magnet) was dipped in corrosive solution for 7 days in polypropylene test tube. Both the control and test magnets were dipped in artificial saliva. The pH of artificial saliva was adjusted to 6.75. After 7 days, the eluate solution was subjected to inductively coupled plasma spectroscopy evaluation to trace the amount of metal ions leached out from the magnets.

Results

The mean values for Nd, Fe, and B were 329, 532, and 316 µg/cm2 respectively. According to the ISO standards, the tested product values of ions leached out should be within the value of 200 µg/cm2. The release of corrosion products stayed significantly under the limit as specified by the ISO standard 22674:2006 for all the specimens in the test groups.

Conclusion

Within the limitations of the study, the indigenously fabricated dental magnet had negligible corrosion in comparison with the control group.

Clinical significance

Magnetic attachments have most commonly been used for the retention of mandibular overdentures. Patients with magnet-retained overdentures have reported a high degree of satisfaction with their dentures. Due to the lack of indigenous fabrication and high costs of imported magnet has led to restricted use of magnets in developing countries. Indigenously developed dental magnets can reduce the cost and make them affordable to our native population. The abutment-friendly benefits of magnetic attachment will help retain the removable prostheses effectively.

Evaluation of Destaining Property of Denture Cleansers on Heat-cured Denture Base Resins using Common Indian Food Stains

[Year:2017] [Month:April-June] [Volume:7] [Number:2] [Pages:7] [Pages No:53 - 59]

Abstract

Aim

To compare the efficacy of two different denture cleansers in removing tea and paan stains from conventional and high-impact heat-cured denture base resins and also to find out the duration of contact required by the dentures with cleansers, for best results.

Materials and methods

A total of 80 specimens (40 conventional and 40 high impact) were fabricated. The samples were stained with tea and paan solutions. Stained samples were subjected to immersion in denture cleansers, namely Dentural (sodium hypochlorite) and Fitty Dent (sodium perborate). Optical density values were measured using spectrophotometer at prestain, poststain, postcleansing 15 minutes, postcleansing 8 hours, and post cleansing brushing. The data were analyzed statistically.

Results

High-impact denture base resins stained more than the conventional denture base resin. Staining potential of paan solution was higher than that of tea solution. Dentural (sodium hypochlorite) is superior to Fitty Dent (sodium perborate) in the removal of stains at postcleaning 15 minutes and 8 hours immersion time in both the denture bases and 8 hours immersion time is better.

Conclusion

Both cleansers were effective in removing stains from denture surface, and Dentural is a better cleanser than Fitty Dent for all the postcleansing stages.

Clinical significance

Adequate removal of extrinsic stains from denture surface is essential for the health of the supportive area. The clinician must suggest an acceptable cleansing regime to the patient.

Comparative Evaluation of Antimicrobial Efficacy of Neem, Miswak, Propolis, and Sodium Hypochlorite against Enterococcus faecalis using EndoVac

Abstract

Aim

To compare the antimicrobial efficacy of herbal irrigants neem, miswak, propolis with sodium hypochlorite using conventional needle irrigation and EndoVac irrigation system against Enterococcus faecalis.

Materials and methods

A total of 120 extracted single-rooted mandibular premolar teeth were infected for 21 days with E. faecalis after instrumentation with ProTaper system. Before irrigation procedure, dentinal shavings were collected in 1 mL of sterile broth and incubated. The optical density of each broth was measured using digital colorimeter and initial readings were recorded. Samples were then divided into four groups of 30 teeth each – Group I: Sodium hypochlorite irrigation, group II: Neem irrigation, group III: Miswak irrigation, group IV: propolis irrigation. Each group was further divided into two subgroups – (a) EndoVac irrigation (b) conventional needle irrigation. After irrigation, dentinal shavings were collected and optical density recorded. The values were analyzed statistically with Student's t test and analysis of variance followed by Tukey's honest significant difference test; p-value < 0.05 was considered to be statistically significant.

Results

The postirrigation optical densities in all the groups were significantly lower than preirrigation values. Sodium hypochlorite demonstrated better antimicrobial efficacy followed by propolis, neem, and miswak. Differences in optical density values for all irrigants are higher in EndoVac (p < 0.0001) compared with needle (p = 0.0009) group, but it failed to reach statistical significance.

Conclusion

Sodium hypochlorite proved to be a better irrigant followed by propolis, neem, and miswak. EndoVac irrigation system was more effective for elimination of E. faecalis than needle irrigation group.
