Background:Skull radiographic examination is a potentially useful procedure for the personal identification in cases where fragments of skull persist with no likelihood of identification based on dental arch.Aims:The study was to determine the uniqueness and reliability of combined frontal sinus (FS) and nasal septum (NS) patterns as observed on posterioanterior (PA) cephalograms for personal identification.Materials and Methods:The randomly selected 149 digital PA cephalograms taken on Kodak 8000C Digital Panoramic and Cephalometric system were evaluated for patterns of FS and NS. Also the distribution of lobulations, area, and ratio of height/width of FS was calculated. The data obtained was statistical analyzed using Pearson's coefficient correlation.Results:FS symmetry was observed in 78.5% and asymmetry in 7.3% subjects. Bilateral aplasia was noticed in 5.3% and unilateral aplasia in 8.7% of subjects. The total lobulation of FS was noted more in males on both sides while center lobes were observed slightly more in females. The straight NS was maximally seen followed by reverse sigmoid. The mean ratio of width/height of FS was observed more in males and highly significant correlation was observed with both sexes. The mean area of FS was noted more in males. There was significant correlation found between patterns of NS and FS except in right dominated asymmetrical FS.Conclusion:The combined use of FS and NS patterns could be used as method for identification by exclusion in forensics.

PurposeThe present study was aimed to investigate the variation of soft palate morphology in different age and gender groups. The correlations of radiographic velar length (VL), velar width (VW), pharyngeal depth (PD), and Need's ratio with soft palate variants were also studied in the North Indian subpopulation.Materials and MethodsThe study sample consisted of 300 subjects aged between 15 and 45 (mean: 31.32) years. The velar morphology on lateral cephalograms was examined and grouped into six types. The results obtained were subjected to a statistical analysis to find the correlation between variants of the soft palate with gender and different age groups.ResultsThe most frequent type of soft palate was leaf shaped (48.7%), and the least common was crook shaped (3.0%) among both the genders and various age groups, showing a significant correlation. The mean VL, VW, and PD values were significantly higher in males and significantly correlated with the types of soft palate. A significant correlation was observed between the mean VL, VW, PD, and Need's ratio with various age groups, showing an inconsistent pattern with an increase in age. The types of soft palate, gender, and Need's ratio were also significantly correlated, with an overall higher mean value of the Need's ratio among female subjects and the S-shaped soft palate.ConclusionThe knowledge of a varied spectrum of velar morphology and the variants of the soft palate help in a better understanding of the velopharyngeal closure and craniofacial anomalies.

Objectives: The purpose of the study was to evaluate and compare the clinical efficacy and the durability of propolis and Light-cured ormocer-based desensitizer (Admira Protect, Voco: Cuxhaven Germany) in the treatment of dentin hypersensitivity (DH). Materials and Methods: The study was conducted over a period of 2 months on 13 patients with 72 hypersensitive teeth, randomly allocated into three treatment groups: Group A: Treated with Propolis, Group B: Admira protect (Voco: Cuxhaven Germany), and Group C: Sterile water (Placebo control). Baseline sensitivity was recorded by the operator using tactile and evaporative stimuli. Visual analog scale (VAS) was used to record the degree of sensitivity perceived by the patients. All the groups received applications of allotted materials on day 1, 7, 14, and 21. After each applications VAS scoring was recorded. On day 30 and 60, only pain evaluation was done to determine the durability of each test materials. Statistical Analysis: One-way ANOVA, repeated measure ANOVA and post hoc test was done for multiple comparison. Results: All the groups showed significant results in reducing DH. Among Groups A and B, Group B showed immediate postoperative result at the end of the 1 st week. Conclusion: Both the test materials were effective in reducing DH but Admira protect was found to be more efficient in reducing pain with longer duration of action (CTRI regd no: CTRI/2017/12/010755).

Resolution pharmacology has gained paramount importance in the field of medicine. Resolvins are specialized pro-resolving lipid mediators (SPMs). They are natural bioactive agents involved in the resolution of inflammation. They function when uncontrolled inflammatory processes are developed. Lipoxins, resolvins, protectins, and maresins are families of mediators that are under SPM. In recent years it has become evident that periodontitis is a multifactorial inflammatory disease initiated by oral microbial biofilm. This review focuses on understanding the role of resolvins, endogenous lipid mediators in overall oral health, and periodontal inflammation that modulate cellular fate and resolution.
