    Saliva is a fluid secreted by the salivary glands that keeps the oral cavity moist and also coats the teeth along with mucosa. The salivary gland possesses tubuloacinar units, and these are merocrine. The functional unit of the salivary glands is the terminal secretory piece called acini with a roughly spherical or tubular shape. It also consists of branched ducts for the passage of the saliva and also plays an important role in the production and modification of saliva. Each type of duct is lined by different types of epithelia, on the basis of its location. Myoepithelial cells are contractile cells with respect to intercalated and secretory endpieces. Parotid, submandibular, and sublingual glands are the major salivary glands. The minor salivary glands are labial and buccal gland, glossopalatine gland, and palatine and lingual glands. Saliva plays an important role in mastication, speech, protection, deglutition, digestion, excretion, tissue repair, etc. Secretion stimulated in response to sympathetic stimulation will differ in protein and electrolyte from that due to parasympathetic stimulation. The concentration of saliva depends only on the rate of flow and not on the nature of stimulus. Saliva guides the clinician toward the optimal mode of treatment and guides the patient toward ultimate prognosis

    Get PDF
    ABSTRACTOral route is the most convenient route of drug administration in many diseases and till today it is the first way investigated in the development ofnew dosage forms. The major problem in oral drug formulations is low and erratic bioavailability, which mainly results from poor aqueous solubility,thereby pretense problems in their formulation. More than 40% of potential drug products suffer from poor water solubility. For the therapeuticdelivery of lipophilic active moieties (biopharmaceutical classification system Class II drugs), lipid-based formulations are inviting increasingattention. Currently, a number of technologies are available to deal with the poor solubility, dissolution rate, and bioavailability of insoluble drugs.One of the promising techniques is self-microemulsifying drug delivery systems (SMEDDS). SMEDDS have gained exposure for their ability to increasesolubility and bioavailability of poorly soluble drugs. SMEDDS, which are isotropic mixtures of oils, surfactants, solvents, and co-solvents/surfactantscan be used for the design of formulations to improve the oral absorption of highly lipophilic drug compounds. Conventional SMEDDS are mostlyprepared in a liquid form, which can have some disadvantages. SMEDDS can be orally administered in soft or hard gelatin capsules and form finerelatively stable oil-in-water emulsions. Solid-SMEDDS are prepared by solidification of liquid/semisolid self-micron emulsifying ingredients intopowders, have gained popularity. This article gives a complete overview of SMEDDS, but special attention has been paid to formulation, design,evaluation, and little emphasis on application of SMEDDS.Keywords: Self-microemulsifying drug delivery system, Surfactant, Oil, Co-surfactant, Bioavailability, Lipophilic, Biopharmaceutical classificationsystem Class II drugs

    Background: Anatomy provides a platform of knowledge indispensable to all the branches of medicine. Students have to learn many new concepts and tongue-twisting terminologies, making this subject difficult to comprehend. It has been seen that a range of innovative, proactive, simple, hands-on approach strategies can achieve maximum student engagement and help them learn. Aim is to take students from the traditional view of anatomy as a subject that require surface learning (rote learning, memorization) to one that can lead to deep learning through understanding. Keeping all this in mind a study was planned to develop an innovative method of teaching anatomy to 1st year MBBS students.Methods: The diagrams of sagittal and horizontal sections of the brain were selected, marked and cut into jigsaw pieces. Students were given an incomplete jigsaw puzzle and a set of questions. The answer to these questions helped them complete the puzzle. Perception of students who consented to participate in the study was noted.Results: Out of 98 students who participated in the study 61.2% wanted to participate in similar activities in future in anatomy and 57.1% felt that it helped them in understanding the topic. For 52.1% it was a useful self-learning tool and for another 48.9% students solving the puzzle was a challenging experience.Conclusions: Jigsaw puzzle is an efficient way for students to become engaged in their learning.

    Get PDF
    Dermoid cyst (cystic teratoma) showing well differentiated derivatives of all three germs cell layers, is a benign germ cell tumour. Ovaries remain the commonest site. Paravaginal dermoid cyst is a rare occurrence. Pre-operative diagnosis is usually difficult in majority of cases. They constitute less than 4% of all extragonadal teratomas. A 28-year old, P2L2 female presented with paravaginal cyst, 10Ă—10cms, non-tender, soft swelling, cystic in consistency occupying posterior and left part of rectovaginal septum. Trans vaginal excision of cyst under regional anaesthesia done. Cyst was ruptured while excision showing putty material with tuft of hairs. A retrospective diagnosis of mature teratoma/paravaginal dermoid cyst was made on histopathological examination. Paravaginal dermoid cyst, a benign cystic teratoma is a very rare occurrence. Transvaginal excision of dermoid cyst under anaesthesia remains treatment of choice. Retrospective diagnosis on histopathological examination remains confirmatory as it may be missed on sonography if teeth are not present in dermoid cyst

    Objective: To evaluate Indian dental students’ perception of seeking international dental higher education during COVID-19. Material and Methods: We conducted an online survey among the dental students. A self-administered questionnaire was prepared, which had information on country choice, reasons for the decision to study abroad, measures to be taken by the foreign universities because of COVID-19, the application’s status, current plan, and opinions on exploring other possibilities. Results: Four hundred students constituted the final sample, out of which the majority were females (69.3%). Most of the students were not sure about their status in the application process (63%). The current plan to study abroad remained uncertain for almost half of the students (50.2%). Concerning the status of the application process, a significantly higher number of female students were “not sure” and are still “searching colleges” (p<0.001). Similarly, a higher number of females were “uncertain” or “postponed” or “canceled” when compared to the males concerning the current plan to study abroad (p=0.001). Also, a significantly higher proportion of female students cited the study budget as the main deterrent for pursuing a career abroad and opined that “flexible study options” will help them get admissions post-COVID-19 (p=0.001 and 0.035). Conclusion: A substantial impact was perceived by Indian dental students concerning higher education abroad, more among females
