Computational Simulation of Fluid Dynamics in Thin Films

We investigate the formation of droplets in a thin liquid film on a solid substrate due to the combined action of surface tension and van der Waals forces. Current models for droplet formation assume that droplets have a shallow profile. By removing that assumption and numerically solving for stable droplet profiles, we have modelled droplets that separate from the substrate on which they sit

Evaluation of shear bond strength of a composite resin to white mineral trioxide aggregate with three different bonding systemsa: an in vitro analysis

Background: Mineral trioxide aggregate (MTA) is a biomaterial that has been investigated for endodontic applications. With the increased use of MTA in pulp capping, pulpotomy, perforation repair, apexification and obturation, the material that would be placed over MTA as a final restoration is an important matter. As composite resins are one of the most widely used final restorative materials, this study was conducted to evaluate the shear bond strength of a composite resin to white mineral trioxide aggregate (WMTA) using three different bonding systems namely the two-step etch and rinse adhesive, the self-etching primer and the All-in-one system. Material and Methods: Forty five specimens of white MTA (Angelus) were prepared and randomly divided into three groups of 15 specimens each depending on the bonding systems used respectively. In Group A, a Two-step etch and rinse adhesive or ‘total-etch adhesive’, Adper Single Bond 2 (3M/ESPE) and Filtek Z350 (3M ESPE, St Paul, MN) were placed over WMTA. In group B, a Two-step self-etching primer system, Clearfil SE Bond (Kuraray, Medical Inc) and Filtek Z350 were used. In Group C, an All-in-one system, G Bond (GC corporation, Tokyo, Japan) and Filtek Z350 were used. The shear bond strength was measured for all the specimens. The data obtained was subjected to One way Analysis of Variance (ANOVA) and Scheffe’s post hoc test. Results: The results suggested that the Two-step etch and rinse adhesive when used to bond a composite resin to white MTA gave better bond strength values and the All-in-one exhibited the least bond strength values. Conclusions: The placement of composite used with a Two-step etch and rinse adhesive over WMTA as a final restoration may be appropriate

Report of Platythomisus octomaculatus (C. L. Koch, 1845) and Platythomisus sudeepi Biswas, 1977 from India (Araneae, Thomisidae)

The genus Platythomisus Doleschall, 1859 presently comprises 13 valid species, nine known from Africa and four from Asia. All Platythomisus species are known from females only, except P. jucundus Thorell, 1894 and P. sudeepi Biswas, 1977 from both sexes and P. quadrimaculatus from juvenile. Only, P. sudeepi was reported from India. Platythomisus octomaculatus (C. L. Koch, 1845) is recorded after 120 years of its last report; newly recorded from Assam, India which extends its distribution from the previously known localities, Java and Sumatra. Platythomisus sudeepi is newly recorded from the Maharashtra State. The variation in the number of abdominal spots on juvenile, sub-adult and adult of P. octomaculatus observed during rearing is reported. Although, the species name 'octomaculatus' suggests eight spots, we observed that the anterior pair of abdominal spots is fused in adults

Acupuncture in the Management of Orofacial Pain and Related Disorders: A Review

Oro-facial pain and temperomandibular dysfunction are deemed upon as multifaceted problems and can pose major therapeutic problem in dealing with them. Evidence from clinical studies suggests that acupuncture may be useful in the treatment of orofacial pain, temperomandibular dysfunction and related disorders otherwise resistant to conventional treatment modalities.  Acupuncture is an ancient healing technique that has regained its lost popularity in the last two decades. The present paper attempts to review this forbidden procedure and its role in improving the quality of dental care provided to the patients especially in the management of orofacial pain, temperomandibular dysfunction, dental anxiety, gag reflex, xerostomia and trigeminal neuralgia. &nbsp

Drug utilization study of antibiotics in infectious diseases in a tertiary care hospital

Background: Infectious diseases represent a major cause of mortality and morbidity in India. Irrational use of antibiotics can cause increase adverse drug reaction, leading to antibiotic resistance and increase in the treatment cost. Hence pattern of use of antibiotics need to be studied, therefore the aim of our study is to observe the antibiotics prescription pattern and drug utilization in department of medicine indoor patients at our tertiary care hospital.Methods: This was a prospective observational study carried out among indoor patients admitted in medicine ward and was conducted between January 2018 to March 2018 in Basaveshwara Teaching and General Hospital attached to M.R. Medical College, Kalaburagi. The data that was obtained was analysed and presented as percentages using descriptive statistics.Results: 100 patients were enrolled. The main reasons for admission were for diagnosis of respiratory tract infection (36%), GIT disorders (24%), Zoonotic disease (10%), Urinary tract infection (19%) and viral fever (11%). Most common antibiotic prescribed was ceftriaxone (40%), followed by piperacillin (26%). Average number of antibiotics per prescription was 1.7.Conclusions: For a wide spectrum of clinical diagnoses variety of drugs were utilized from various drug classes. Results showed that Cephalosporin was extensively used. As antibiotics are most commonly prescribed drugs and report of misuse is not uncommon so proper strategy like educational intervention and antibiotic policy are necessary to control this

Accelerated Orthodontics

Clinical orthodontics is ever dynamic branch of Dentistry. Traditionally orthodontics was always considered as aesthetic treatment of face & also needed for proper oral oral function. This treatment may take up 2–3 years of total duration. The chapter describes changing trends in this aspect wherein we speed up the treatment by various methods thus reducing the overall time duration. These modalities include alteration in bio mechanics, pharmacological, chemical & by biological means. It is also cautioned here that the clinician has to take up these changing trends based on sound clinical knowledge & evidence based applicability

Management of a permanent maxillary first molar with two disto buccal canals with the aid of spiral computed tomography: a case report

Human molars show considerable anatomic variations with respect to number of roots and root canals. The most common form of the permanent maxillary first molar has three roots and four canals, two mesiobuccal canals and one distobuccal and palatal canal each. 98.3% of maxillary first molar have been reported to have a single distobuccal canal. Two canals were found only 1.7% of the time, hence showing the second disto buccal canal to being a rare occurrence. Conventionally radiographs are used to determine root canal anatomy, which is a 2- dimensional representation of a 3-dimensional object. Diagnostic methods like spiral computerized tomography where a 3 dimensional data is acquired are useful to determine complex morphology. This case report presents the management of a maxillary first molar with two disto buccal root canals confirmed with the aid of computed tomography along with the conventional radiographic method. Computed Tomography scan slices revealed two separate distobuccal canals at the coronal 3rd of the root. The second distobuccal canal was missing in the middle and apical 3rd indicating; it might have joined the distobuccal canal at the middle 3rd area

Ultrasonographic evaluation of cervical length and amniotic fluid index as predictor of pregnancy outcome in case of preterm premature rupture of membrane

Background: Preterm premature rupture of membrane (PPROM) is among the most important cause of the perinatal morbidity and mortality. We sought to determine whether cervical length and amniotic fluid index individually or in combination can predict the pregnancy outcome in cases of PPROM.Methods: The prospective observational study was done on 170 women complicated by PPROM with gestational age between 24-36+6 weeks. They were categorized into three groups Group I.24-28 weeks, Group II.28+1 to 32 weeks and Group III. 32+1 to 36+6 weeks. Cervical length and amniotic fluid index were measured using trans abdominal ultrasound within 24 hr of admission. Maternal outcomes were recorded in terms of latency period, chorioamnionitis, and abruption , and neonatal outcomes were recorded in terms of birth weight, first minute APGAR score 5 cm had a greater mean latency period (8.32±1.25 days) which increased their risk of developing chorioamnionitis as compared to women with PPROM having AFI ≤5 cm, who had a shorter mean latency period (7.63±1.07 days) and a lower risk of developing chorioamnionitis (p value <0.0001).Conclusions: Latency is inversely related to period of gestation. A long cervical length and increased amount of AFI correlates with increased latency, increased risk of chorioamnionitis and increased neonatal complications
