A Study on Marginal Continuty of Shoulder and Chamfer Finish Line of Metal Crown

Update Dental College Journal (2017)

Mahenaz Munira Faruk Nahar Nasima Khatun Mahamuda Khatun Alia Sultana

Background: Marginal continuty is very important for the longevity of restoration .The junction between the cemented restoration and the tooth is always a potential site for recurrent caries, gingivitis and periodontitis and ultimately failure of crown as well as teeth.Hypothesis: Marginal continuity for shoulder finish line for anterior teeth and chamfer for posterior teeth are equally effective.Objectives: To evaluate the marginal continuity of metal crown.Methods: Thirty extracted human teeth were prepared with shoulder margin (group-A) and another thirty teeth were prepared with chamfer (group-B) as methodically. Metal crown was fabricated by lost wax technique of casting procedure. All of the crowns (both group-A and group-B) were cemented by glass inomer luting cement. Each crown was sectioned in faciolingual direction at the midpoint of each surface by slow speed isomet saw. The sectioned crowns were examined under sreriomicroscope for measurement of marginal continuty. Data were collected on the basis of marginal continuty of each crown was compared. Collected data were processed and analyzed using SPSS (Statistical Package for Social Service) version 12.Results: The frequency distribution of marginal continuity were statistically non significant between two groups.Conclusion: All metal crowns had greater continued margin than discontinued margin.Update Dent.

Extraction Of Natural (Dab Shell And Latkan) Dyes Blended It With Synthetic (Reactive Red And Methyel Orange) Dyes And Observe Their Dyeing Effects On Silk And Cotton Fibre

Astaq Mohal Khan Md Lutfor Rahman Md. Kobad Hossain Debashis Talukdar Mahamuda Khatun

Natural (Dab shell and Latkan) dyes were extracted by the conventional method. Blended it with synthetic (Reactive Red and Methyl orange) dyes, applied on silk and cotton fibre and observed their dyeing effects. It was found that in case of silk fibre using dab shell + latkan dyes + Reactive Red dye and dab shell + Latkan dye + Methyl orange produced deep chocolate and deep brown colour and shades. But in case of cotton fibre the colour and shade changed to light pink and light cream shade respectively. Light and washing fastness were also observed both kinds of fibre and found fine fastness to light and then washing. Key Word: DabShell, Latkan fruits, Reactive Red, Methyl Orange, Coper Sulphate, Acetic acid and Soap.

An investigation on heavy metal tolerance and antibiotic resistance properties of bacterial strain Bacillus sp. isolated from municipal waste

Journal of Microbiology and Biotechnology Research (2017)

Amalesh Samanta Paramita Bera Mahamuda Khatun Chandrima Sinha Pinaki Pal

The objective of our present study was to isolate heavy metal tolerant and antibiotic resistant microorganisms, the site selected being the K.M.C.’s Waste Dumping Yard, Dhapa, Kolkata, West Bengal, India, based on the extent of pollutants being discharged and the land waterways being polluted by the effluents and waste being dumped by the household and numerous industrial units. The isolated strain showed amylase & protease positive, spore forming, Grampositive bacilli and exhibited growth in wide range of substrates, temperature (30°C-40°C) & pH (6.0-11.0). Based on the 16S rDNA molecular technique, it was found that the isolate was Bacillus sp. and has a mega plasmid. Moreover it was found to grow in presence of a wide range of metals namely nickel, cadmium, chromium and cobalt in the order Cd2+> Cr6+> Ni2+> Co2+. And also it was observed that the isolate was resistant to a wide range of antibiotics namely Kanamycin (30μg/disc), Ampicillin (25μg/disc) and Methicillin (5μg/disc). Plasmid curing result showed the loss of antibiotic and heavy metal resistance profile in the isolated strain and confirms a relationship between antibiotic and heavy metal resistance with plasmid. Heavy metal tolerance test showed maximum microbial tolerance to cadmium and minimum tolerance to cobalt. This heavy metal resistant organism could be a potential agent for bioremediation of heavy metals polluted environment. Keywords: Bacillus sp, heavy metals, MTC, antibiotic resistance, plasmid curing, 16S rDNA gene sequencing.
