Oral Health and Vitamin B12: A Review

ABSTRACT Vitamin B12 occurs in various forms and has a variety of names. It is unusual in its origin. Most vitamins can be made by a wide variety of plants and specific animals but no plant or animal has been found capable of producing Vitamin B12 and the most common sources of this vitamin appears to be small microorganisms like bacteria, yeasts, molds, and algae. Its deficiency causes nervousness, generalized weakness, megaloblastic anemia, dementia, etc. Intra-oral signs and symptoms include pale mucosa, recurrent aphthous stomatitis, candidiasis, angular chielitis, glossitis, etc. This paper reviews vitamin B12 structure, metabolism, function, sources, deficiency and correlation with oral health along with therapeutic measures

Multidisciplinary Oral Management in Cancer Therapy Part III: Post Cancer Treatment

Post-therapy preventive and therapeutic strategies for dental management are essential. Usually most of the dental procedures that were postponed before and during oncologic therapy can be performed post therapy. This post-cancer therapy multidisciplinary oral management is directed at minimizing recurrence of disease, providing palliation, and improving the quality of life of patients. Hence, this paper provides a pathway of multidisciplinary oral management following cancer therapy

Multidisciplinary Oral Management in Cancer Therapy Part II: During Cancer Treatment

One of the most important patients-related variables is the patien

Multidisciplinary Oral Management in Cancer Therapy Part I: Pre-Surgical Management

Oral cavity suffers a short-term and long-term complication from cancer therapy. An appropriate evaluation and elimination of potential source of oral infection before cancer therapy is vital and must. The best management strategy encompasses a prophylactic local and systemic combination therapy that has implications for post-treatment oral comfort and function, thus promoting consistent high standards of oral care through a co-ordinated team approach is warranted. This paper provides a multidisciplinary oral management prior to cancer therapy

Engineering crops for tolerance against abiotic stress through gene manipulation

Plant genetic engineering took birth in the mid-eighties when, for the first time, plants were successfully engineered for improved virus, herbicide and insect resistance. This sphere has been ever-increasing since then. Abiotic stresses (such as high salt levels, low water availability leading to drought, excess water leading to flooding, high and low temperature regimes, etc.) adversely affect crop plants. The genetic responses of plants to these stresses are complex involving simultaneous expression of a number of genes. Till the early-nineties it was inconceivable that there would be any success in attaining the goal of improving resistance of crop plants to abiotic stresses. Continuing efforts of the stress biologists have resulted in engineering of plants resistant to low temperature, high temperature and excess salinity. A satisfactory progress has also been achieved in the area of generating plants resistant to water stress and flooding. While what has been achieved is impressive, it is still a challenging task to pyramid useful genes for high-level resistance to such stresses. The limiting factor in extension of biotechnology to abiotic stresses is the lack of information on what are the 'useful genes'-genes which would lead to better stress tolerance. We have reviewed how these genes are being searched to enable further development of strategies for stress management in crop plants. This is important because the strategics for coping with the abiotic stresses (and also for several other applications in plant biotechnology) have also come through the research work of scientists working on as diverse organisms as bacteria and fish

Single Visit Feeding Appliance for 1‑day‑old Neonate with Cleft Palate Using Safe Dental Putty‑Gauze Hybrid Impression Technique for Maxillary Impression

Cleft lip and palate is one of the most common craniofacial anomalies of humans. Intraoral impression making is the first clinical step in the fabrication of feeding appliance for infants with oro‑nasal communication. It is difficult to control the flow of the impression material in the cleft area and undercuts in a child patient. This clinical report presents a simple and safe impression technique for maxillary impression making in neonates and infants with cleft palate. A gauze piece was used to confine the impression material during functional movements of sucking while impression making in an awake child to avoid the risk of aspiration or swallowing.Key words: Cleft palate, feeding plate, maxillary impression, obturato

Basics of clinical diagnosis in implant dentistry

Implant-based prosthetic rehabilitation requires an understanding of associated anatomical structures. The ultimate predictability of an implant site is determined by the existing anatomy as related to dentition and the associated hard and soft tissues. Meticulous clinical assessment helps in determining the suitability of the potential site for implant placement. The purpose of this article is to present the clinical assessment for dental implants' placement to modulate peri-implant tissue characteristics in individual clinical need

Optimisation of FDM process parameters by Taguchi method for imparting customised properties to components

Customisation of material properties by route of controlling the process parameters is a landmark ability of the additive manufacturing (AM) processes. Parametric optimisation of fused deposition modelling process using Fortus 250mc modeller is accomplished for conical primitives of constructive solid geometry in the present research. Experiments were designed according to the Taguchi technique for four factors at three levels each – slice height (SH), contour width (CW), raster width and air gap (AG). Analysis of signal-to-noise ratios is utilised for establishing the optimal process parameters and the relative percentage contribution of factors is estimated using ANOVA. Optimal levels of process parameters are found to vary with the variation in the type of basic shape of primitive. It has been established that AG has a maximum impact over the part build volume followed by CW and SH. Also, it can be safely concluded that the interaction effect of parameters is relatively less important
