Knowledge, Attitude, and Practices in Research among Postgraduate Students in Dental Schools of Udaipur, Rajasthan, India

Results: In the present study, 27.7% from second year and 45.6% from third year PGs know the definition of research hypothesis, and this difference was statistically significant (p < 0.05). The difference in research practice of second and third year PG students was statistically significant for all parameters except presented poster or research paper in a conference and experience in writing research protocols. The lack of time due to vast curriculum of PG students (37.7%) and lack of interest (36.6%) were the personal reasons, and lack of time (28.1%) and inadequate support by mentors/assistant (23.5%) were among the institutional reasons for not conducting research.

Perception about Self-medication Practices for Oral Health Problems among Patients attending Dental Hospital, Udaipur, Rajasthan, India

Self-medication is the treatment of common health issues with pharmaceuticals, particularly, planned/designed and labeled for use without medical supervision and endorsed as protected and effective for such use.1 Self-medication is commonly practiced everywhere throughout the world.2-4 Medicines for self-medication are frequently called “nonprescription” or “over the counter” (OTC) and are accessible without a specialist’s prescription through pharmacies. Self-medication is now progressively being considered a part of self-care.5 “The desire to take medicine is perhaps the greatest feature which distinguishes man from animals” — William Osler.6 According to WHO, health is characterized as a state of complete physical, mental, and social well-being and not merely the absence of diseases or infirmity.7 Self-administered medicines is an age-old practice. Some of the reasons for growth in self-medication are the inclination of self-care, feeling of sympathy toward relative in sickness, lack of health administrations, poverty, ignorance, doubts, extensive advertisements of drugs, and accessibility of medications in establishments other than pharmacies.8 Sale of antibiotics and physician-endorsed drugs which are part of schedule H, by a nonpharmacist and without a valid prescription are banned/prohibited according to the Drug and Cosmetics Act of 1945 in India.6 Poor diagnostic ability compounded by a constrained knowledge of proper administration results in 1,2,5Postgraduate Student, 3Professor and Head, 4Private Practitioner, 6-8Intern 1-3,5-8Department of Public Health Dentistry, Pacific Dental College & Hospital, Udaipur, Rajasthan, India

Assessment of Patient Satisfaction toward Dental Care Services of Patients visiting Dental Schools in Udaipur, Rajasthan, India

Dental problem are normal now a days.1 Major and minor oral and dental problems require dental schools and hospital services for overall population.2,3 Oral health of the patient has an important effect on patient satisfaction.4 Patient satisfaction with dental care also will impact the future usage of the utilization of dental services.5 Satisfaction can be characterized as the degree of an individual experience compared with his or her desires.6 Nature of treatment depends on facilities available.7,8 Awareness in regards to dental wellbeing has prompted to change in patients’ state of mind towards nature of dental treatment.9 The role of dental specialist is critical to enhance the nature of dental administration and to expand patients’ fulfillment level, readiness to utilize the administration once again and to refers the dental services to others.10 So, as to enhance the patients’ fulfillment, the nature of dental treatment gave alone is insufficient, alternate components which have a role are the environment in which it is given, the free charged gave in the dental school and hospital.11 Dentist-patient interaction quiet association amid a discussion including subjective and emotional viewpoints have been exhibited to influence tolerant consistence with clinical guidance and follow-up visits.5 Understanding variables and components that influence fulfillment level can help as enhance the nature of administrations gave by the dental group, fortify the trust amongst patient and dental practitioner and subsequently enhance oral wellbeing.5,12,13 Chung et al recommended elements that specifically influence ability to visit a hospital again are desire level toward hospital, reliability of the medicinal care, accessibility to the diagnosis, expanses for medicinal care and patient fulfillment level.13 1Professor and Head, 2,5,8Postgraduate Student, 3,4,6,7Final Year Undergraduate

ielectric Studies of Cd-Substituted PMN Relaxor

Single phase perovskite ceramic Pb(Mg1/4Cd1/12Nb2/3)O3 (PMCN) was prepared by the high temperature solid-state reaction method. Dielectric constant and loss tangent were measured over a frequency range 1 kHz to 1 MHz in the temperature region −40 to 115°C. Dielectric studies revealed the relaxor behaviour with diffuse phase transition. The frequency dependence of the temperature of the permittivity maximum (T m ) has been modeled using Vogel-Fulcher relation. The dielectric relaxation in PMCN is found to be analogous to the magnetic relaxation in spin-glass system.

Diffuse Phase Transition in Pb2Sb3DyTi5O18 Ceramic

Polycrystalline sample of Pb 2 Sb 3 DyTi 5 O 18 , a member of tungsten-bronze (TB) family, was prepared using a high temperature solid-state reaction technique. XRD analysis indicated the formation of a single-phase orthorhombic structure. The dielectric studies revealed the diffuse phase transition and the transition temperature found to be at 301°C. The activation energy was estimated to be 0.62 eV from the temperature variation of dc conductivity. The nature of variation of dc conductivity with temperature suggested NTCR behaviour.

Ferroelectric Phase Transition in Pb[(Mg3/4Zn1/4)1/3Nb2/3]O3 Ceramic

Pb[(Mg 3/4 Zn 1/4 ) 1/3 Nb 2/3 ]O 3 (PMZN) ceramic was prepared by columbite precursor method. The structural analysis revealed the cubic phase of PMZN at room temperature. Dielectric studies show the relaxor behaviour with diffuse phase transition. The transition temperature (T m ) was found to be at 40°C at 1 kHz. The frequency dependence T m has been modeled using Vogel-Fulcher relation. The dielectric relaxation in PMZN is found analogous to the magnetic relaxation in spin-glass system. The relaxor behaviour in PMZN has also been examined through admittance spectroscopy.
