Research Article: Evaluation of the Effect of Maxillary Incisor Labiolingual Inclination & Antero-Posterior Position on Smiling Profile Esthetics – A Computer Aided Photographic Study
Prathik Doshi, Ajit Kalia, Wasu Patil, Gaurav Gupta and Danish Intesaab Ahmed*
Objective: To test the null hypothesis that there was no effect of maxillary incisor labiolingual inclination and Anteroposterior (AP) position on smiling profile esthetics in young adult females.
Sample population: Subjects to be screened were young adult females from Indian population.
Subject and method: A total of 5 subjects were selected after screening Indian population for the study. A total of 145 images of 5 subjects were assessed by each member of professional and non-professional groups. Professional group consist of 10 orthodontists of age group 28-35 years & non-professional group consist of 10 laypersons of age group 28-35 years.
Results: the average ratings for overall images (all images combined) did not differ significantly between orthodontists and laypersons. (P-value > 0.05).The overall distribution of attractiveness significantly differs across various types of images (P-value < 0.001) Depending on rating received images were grouped as most attractive, attractive, interim attractive, relatively unattractive and unattractive.
Conclusion: This study concludes that there is an effect of maxillary incisor labiolingual inclination and Anterioposterior (AP) position on smiling profile esthetics in young adult females selected from Indian population

Research Article: Evaluation of the Effect of Three Different Esthetic Components on Smile Attractiveness
Navid Haghayegh Khorasani*
Objectives: To evaluate the perceptions of dental students, art students and lay-people, on the impact of different esthetic components on smile attractiveness.
Materials and methods: A photograph of an ideal smile was selected and digitally manipulated to create the following smiles: an ideal smile (IS), a smile with midline diastema (D1), a smile with Midline Deviation (MD), and a smile with Reversed Smile Line (RSL). The manipulated photographs were presented to three groups: 44 dental students, 44 art students and 44 lay-people. Raters were asked to rank the photographs from the least to the most attractive; then, each photograph was awarded a mark from 0.0 to 10.0.
Results: In all groups, ideal smile received the most score. Regarding the variations, dental students and art students rated MD the most attractive and D1 and RSL the least attractive, but lay people rated MD the best, D1 less attractive and RSL the least attractive.
Conclusion: Reverse smile line, midline diastema and maxillary midline deviation have a great negative impact on the attractiveness of the ideal smile. However, reverse smile line and midline diastema, overwhelmingly decrease attractiveness ratings, in comparison with maxillary midline deviation.

Review Article: Bioactive Compounds from Mentha Spp. As a Potential Antifungal against Species of Candida. A Review Article
Paula Cristina Anibal, Simone Nataly Busato de Feiria, Anderson Laerte Teixeira, Jose Francisco Hofling*
Fungi of the genus Candida, have become more frequent as agents of fungal infections, particularly associated with immunocompromised patients. It has been reported in the literature an increasing occurrence of resistance of these microorganisms to antifungal drugs available for the treatment of these pathologies, such as polyenes and azoles agents, which has led researchers in this field to seek new alternatives for drugs that have action against these organisms. Medicinal plants have long been used in the treatment of diseases through their extracts, essential oils and their bioactive components which makes them great source of new drugs research. Essential oils extracted from plants of the genus Mentha spp. have demonstrated potential of antimicrobial action, especially antifungal activity against fungi of the genus Candida.

Detection of early stage carious lesions is critical for active prevention. Near-Infrared Fluorescence (NIRF) is an investigational imaging modality. The purpose of this study was to investigate the feasibility and validity of NIRF imaging using an imaging agent in the detection of early occlusal and interproximal caries on extracted human teeth.
Method: Infiltration rate of OsteoSense750 (OS750, bisphosphonate derivative) into enamel carious lesions was measured using a florescence microscope, and the correlation between infiltration and lesion depth was determined. Stability of OS750 fluorescence signal intensity was examined as a factor of dilution ratio and time of excitation illumination exposure. The correlation between fluorescence intensity and carious lesion depth measured by high resolution 3D X-ray microscope was assessed. Finally, diagnostic performance (sensitivity and specificity) of NIRF imaging was compared to ICDAS for occlusal caries and to bitewing radiographs for interproximal caries using bootstrap resampling methods.
Results: The mean infiltration rate of OS750 into enamel carious lesions was 93% and there was little correlation between infiltration and lesion depth (R= -0.08987). OS750 maintained 100% of fluorescence intensity for 15 minutes with 1:10 dilution and 80% intensity for 5 minutes with 1:100 dilution. The correlation between OS750 fluorescence intensity and lesion depth was 0.64745. The sensitivity and specificity for occlusal caries with OS750 were 1.0 and 0.66 versus 0.81 and 0.8 for ICDAS. Interproximal caries values were 0.86 and 0.8 using OS750 and 0.34 and 0.9 by bitewing.
Conclusion: NIRF imaging using OS750 showed excellent properties in infiltration rate and intensity representative of the magnitude of the carious lesion. Diagnostic measures demonstrated much higher sensitivity and NPV than conventional clinical methods supporting the potential of NIR fluorescence imaging with OS750 for early stage caries detection.

Opinion: Periodontal Muscle Training Can Strength the Periodontal Support, Fit Your Teeth, Periodontal Fitness
A total of 505 patients in general practice were asked to respond to a list of 25 obligatory nourishments for a child while going to have the first teeth, for its effectiveness in dealing with patient's periodontal health especially include chewing hard food. They were also asked to select the three effective nutrition for periodontal tissue. The indicts of patient perceived importance of the periodontal health were derived and each compared with actual effectiveness as determined from a sample of 250 patient's opinion.
Although the majority of patient's 18 of 25 nutritions as being very effective, there was no significant association with patient perceived nourishment effectiveness and actual effectiveness. The implications for patient training are discussed.
