RESUMO

Abstract Objective: To evaluate root canal configuration and morphology of premolar teeth among Saudi subpopulations using cone beam computed tomography (CBCT). Material and Methods: In this retrospective cross-sectional study, CBCT images of 314 patients comprising 346 maxillary and 412 mandibular first premolar (FPM) teeth, 298 maxillary and 387 mandibular second premolar (SPM) teeth were analyzed to evaluate the number of roots, root canal morphology, and configuration based on the Vertucci's classification. The average intra-class correlation coefficient value was 0.931. Results: In the maxillary first premolar, 52.6% were two separate rooted and single rooted teeth, with one canal in 81.2% of the maxillary second premolar. Among the mandibular FPM, 96.6% of the teeth had one root and canal, and 97.9% of mandibular SPM had one root and canal. Type 1 canal configuration was seen as most common in all premolars. The number of roots in mandibular premolars did not reveal the difference among gender. Conclusion: Wide variations in root canal morphology and canal configuration system exists among maxillary and mandibular premolar teeth (AU).

RESUMO

CONTEXT: The accurate determination of vertical jaw relation is extremely important for successfully achieving comfort, function and esthetics for an edentulous patient.AIM:The aim of this study was to find a correlation between vertical dimension of occlusion (VDO) and length of right hand palm.METHODS AND MATERIAL:The study was conducted on 60 dentate subjects (30 Males and 30 Females) who fulfilled the inclusion criteria. Anthropometric measurements of vertical dimension of occlusion and length of right hand palm were recorded. Correlation between VDO and length of right hand palm was studied using Pearson's correlation test and unpaired t test used to find correlation among males and females VDO & right palm.RESULTS:Pearson's correlation test showed that VDO in both males (r=0.8001, p value=000) and females (r= 0.9556, p value=000) has strong coefficient correlation with the length of right hand palm. The study also suggested by unpaired t test that there is no statistical correlation between the males and females VDO (t= -0.3366, p value=0.7377) and length of right palm (t= -0.1046, p value=0.9170)CONCLUSIONS: Within the limitations of this study, it was concluded that for males and female subjects VDO and length of right hand palm was highly correlated and this anthropometric measurement can be used to determine VDO in edentulous patient.

RESUMO

Currently, natural products have been used in treating gouty arthritis and are recognized as xanthine oxidase inhibitors. Current study was designed to evaluate in vitro xanthine oxidase inhibitory potential of Gouticin and its ingredients extracts and in vivo hypouricemic activity of gouticin tablet 500 mg twice daily. Ethanol extracts of Gouticin and its ingredients were evaluated in vitro, at 200, 100, 50, 25 microg/ml concentrations for xanthine oxidase inhibitory activity. IC[50] values of Gouticin and its ingredients were estimated. Further, in vivo therapeutic effect of Gouticin was investigated in comparison with allopathic medicine [Allopurinol] to treat gout. Total patients were 200 that were divided into test and control group. Herbal coded medicine [Gouticin] was given to test group and allopathic medicine allopurinol was administered to control group. In vitro, Gouticin has the highest percent inhibition at 96% followed by Allopurinol with 93% inhibition. In vivo study, mean serum uric acid level of patients was 4.62 mg/dl and 5.21mg/dl by use of Gouticin and Allopurinol at end of therapy. The study showed that herbal coded formulation gouticin and its ingredients are potential sources of natural xanthine oxidase inhibitors. Gouticin 500 mg twice daily is more effective than the allopurinol 300mg once daily in the management of gout.

RESUMO

Pyrexia and inflammation are indicatives of various disorders. Modern medicines are available for treatment of pyrexia, but they have few side effects. Several studies are ongoing Worldwide to search natural antipyretic agents with better efficacy and fewer or no side effects. This study was aimed at evaluating the antipyretic activity of Moringa oleifera bark in rabbits against E. coli induced pyrexia. Rectal temperature was recorded with digital thermometer at 0 h and E.coli suspension was injected. After 1 h again rectal temperature of the animals was recorded and hydro-alcoholic extract were administered to the treatment groups and paracetamol hydro-alcoholic 50 mg/kg orally to the positive control group. Then rectal temperature was recorded at the interval of one h for 4 h. After the drug administration [at h 1], the decrease in body temperature with the dose of 25mg/kg[-1] during next four h ranged between 1.9-2.6 [degree sign]F as compared to the negative control. At the dose of 50mg/kg[-1] the decrease in temperature was 1.9-3.0 [degree sign]F. The decrease in body temperature at the dose of 100mg/kg[-1] was high, which ranged from 2.3-3.1oF as compared to negative control. Paracetamol, a standard drug, also significantly lowered the temperature but Moringa oleifera at the concentration of 100mg/kg[-1] lowered the body temperature significantly as compared to the negative as well as positive control. Moringa oleifera bark has marked antipyretic activity in animal models and this strongly supports the ethnopharmacological uses of Moringa oleifera bark as an antipyretic plant
