Maxillary defects can occur due to certain bacterial, fungal and viral infections. But in recent time mucormycosis has become prevalent secondary to covid-19 infection. Mucormycosis is an opportunistic fungal infection, which primarily affects diabetic and immunocompromised patients. Surgical excision and debridement of the affected areas can result in significant defects. Reconstruction and rehabilitation of these defects remains a significant challenge for the clinicians because 3-D anatomy of the maxilla serves speech, swallowing and aesthetic roles. This review article discusses the reconstructive and rehabilitative methods of mucormycosis maxillary defects.

Tobacco consumption takes away millions of lives worldwide each year. Several approaches have been adopted to curb this tobacco pandemic. Motivational Interviewing (MI) is a technique that amalgamates several theories of behavior change and models of psychotherapy to overcome the ambivalence of these tobacco users, to motivate them to quit the habit. This article bestows an overview of MI, its principles, core skills, and essential strategies, explicating its application for tobacco cessation.

Objective: The objective was to evaluate the efficacy of MI varnish in preventing white spot lesions in patients with fixed orthodontic therapy. Method The study was performed where 100 patients undergoing orthodontics treatment were allocated randomly to 2 subgroups with differing frequencies of MI varnish application. Degree of mineralisation was measured on the vestibular surfaces of 12 teeth (6 varnish & 6 unvarnished controls) Measurement were taken at 4 sites using camera EOS 750D and then subjected to statistical analysis. Results: The statistical analysis showed difference in the degree of demineralization between treated and untreated teeth, and was statistically significant in terms of time point, frequency of application or specific tooth site. Conclusion: Periodic application of MI varnish can offer some protection against white spot lesions and it is not statistically significant degree if patients have excellent oral hygiene. Additional protection is conferred by applying the product every 3 months compared with every 6 months

Demineralization of teeth or caries is a common health problem among pediatric patients. It is a more serious issue among children from low-income households due to their lack of access to proper dental care. Silver diamine fluoride (SDF) is an effective agent used to treat demineralization, but experiments are being done to replace it with nanosilver fluoride (NSF). The purpose of this study was to assess the effectiveness of nanosilver fluoride varnish in containing demineralization of primary teeth. A systematic literature review method was used. About 15 articles met the inclusion criteria. Findings are conflicting, but most of the reviewed studies confirmed the effectiveness of an agent with nanoparticles compared to all other alternatives, especially SDF. Apart from suppressing microorganisms that cause demineralization at very low concentrations, agents with nanoparticles protect patients from discoloration of teeth and formation stains. Nanosilver fluoride varnish can be used to replace the current alternatives, but the findings should be used with caution since most of the present studies are experimental.

For the child living in institutions or in foster care homes, the continued Covid-19 pandemic had a major effect and posed many challenges. It includes a scarcity of access to health & oral health care, lack of schooling, poor infrastructure maintenance, lack of nutrition and healthy diet, similarly, as well as lack of emotional and social support, all of which leads to increase prevalence of mental illness among them. If these problems are ignored any further and not detected or managed early, can have a greater impact on overall wellbeing and development of the child. For the event of personality and emotional resilience in any person’s life, Childhood is that the significant time for overall development and health. It's the responsibility of each nation to take care of the children the marginalized and underprivileged. During the current challenging Covid-19 Pandemic, we must always take the commitment of reducing its impact on institutionalized children by addressing the factors and taking measures for overall development of this vulnerable group. The current review was an attempt of addressing the factors or concerns that can arise due to Covid-19 pandemic situation and measures recommended for improving the overall health and wellbeing of the child living in institutions in India.

Short clinical crowns are more prone to crown dislodgment. Therefore, extra retentive features may be warranted. Though, classic retentive techniques are not always possible to apply in fixed prosthodontics. Hence, it may be beneficial to utilize non-conventional methods to enhance retention in situations where retention cannot be obtained from primary and secondary retentive factors. This article describes a modified technique to increase cast metal and porcelain fused to metal crowns’ retention to cast post and core by using a horizontal retentive pin and hole to lock the crown to the cast post and core.

Background/Aim: To date, there is no standard method to evaluate the fit of the implant framework. However, there are many proposed clinical and laboratory methods in the literature with varying accuracies based on numerous factors involved. Therefore, we conducted the current investigation to review the available evidence in the literature, comparing the available clinical as well as laboratory methods in assessing the fit of implant prostheses. Materials and Methods: We searched MEDLINE, PubMed, and Google Scholar databases for relevant studies related to the fit of the implant framework or the degree and effect of misfit. We also used the manual search method to search for any missing articles. Various combinations of key words were used to fit the searching guidelines of each database. Relevant studies of in-vitro and clinical design were included in this review. Results: The majority of the reviewed studies were either clinical or technique papers that proposed various strategies in detecting the fit of the implant framework, with a very limited number of clinical trials related to the topic. Multiple factors suggest that the concept ‘passive fit’ could be achieved in implant prosthodontics with the use of advances strategies. Various clinical and laboratory techniques in assessing the fit of the implant framework were identified. The advantages, drawbacks, and applicability of each technique are discussed. However, the applicability of these technique is clearly limited due to the absence of clinical trials (in vivo studies) assessing their validity and efficacy of such techniques. A slight misfit of the framework to the implant abutment/analogue was also observed in many of the investigated strategies. Conclusions: Due to the variations of techniques and the various parameters assessed by each, we suggest that it might be useful to combine several techniques to determine the accuracy of fit, quantify the effect and degree of misfit, and subsequently estimate the acceptable level of fit, using the reference system for each technique used accordingly.

To integrate with the jawbone and gum tissues, a prosthetic dental material must be appealing, long-lasting, repairable, cleanable, and bio-compatible. In terms of new prosthetic materials, prosthodontics is rapidly evolving. Despite the fact that all artificial materials emit compounds into the oral environment, side effects and unpleasant responses are possible. We utilized Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to conduct an automated and manual search to find clinical studies that looked at the relationship between prosthetic materials and biohazards. A 'ideal' material will have properties that are equal to or very close to those of the material being replaced. One of the most important properties for any material used in the human body is biocompatibility, or more specifically bioactivity. Unlike other implanted materials, the biocompatibility of dental materials varies depending on their structure and state.

Objective: To evaluate the relationship between canine guided and group function occlusion schemes and tooth wear along with salivary factors such as salivary flow rate and salivary pH. Methodology: A cross sectional descriptive study was conducted among 50 subjects, 25 of group function and 25 of canine guided occlusion. Type of occlusion pattern and tooth wear was assessed through clinical intra-oral examination. Lateral excursive occlusion was determined with the aid of Shimstock to confirm tooth contact and the modified ordinal scale was used for evaluating tooth wear. Working side occlusal contact patterns were determined and classified into two groups: canine guided and group function. Unstimulated and stimulated whole saliva sample was collected to assess the pH and salivary flow rate. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 21, IBM Inc. Descriptive data was reported for each variable. As the data was found to be normally distributed bivariate analyses was performed using Independent t test. Level of statistical significance was set at p-value less than 0.05 Results: No significant difference was seen in pH when compared between canine guided and Group function occlusion as p >0.05 whereas flow rate was found to be significantly more in group function. Conclusion: Most of tooth wear in canine guidance is reported in mandibular incisor followed by mandibular molar. No wear was seen in both maxillary and mandibular canines and minimal wear was reported in maxillary incisor. Type of occlusion did not affect the salivary pH rather it affected salivary flow rate.
