As there is an increase in the rate of oral cancer,the surge for the various maxillofacial materials is increasing as well. Materials used for rehabilitation of congenital or acquired defects of patients should fulfil the requirements such as function, longevity, and aesthetics. Defects of face which may be congenital or acquired makes the condition of the affected person very disastrous mentally, physically as well as emotionally. Patient wants facial rehabilitation for a healthy happy life. To provide rehabilitation of these patients, re-evaluation of materials used in the field of maxillofacial prosthesis seems essential. Maxillofacial material should best suit the ideal selection criteria to satisfy the functionality, biocompatibility, aesthetics as well as durability. While the new materials have exhibited many desirable properties, there are also many insufficiencies involved in it. This article presents a systemic review of the evolution, current trends, and future requirements in maxillofacial materials for ensuring psychological well-being. In the recent years, a dramatic increase in the demand for prosthetic rehabilitation of patients with facial defects is seen. Increasing awareness of cancer is resulting in earlier diagnosis and treatment. Unfortunately, many of the surgical techniques are extensive and thus leave large defects that compromise not only function and aesthetics, but also psychosocial status of the patient. These problems require prompt rehabilitation with surgery or prosthetics.1 However, surgical reconstruction is often contraindicated in the presence of large defects or in high-risk patients. Prosthesis offers the advantage of quick, reversible and medically uncomplicated rehabilitation. In addition, the restoration may be readily removed to allow evaluation of the health of the underlying tissues. Historically, many types of materials have been used. Wood, wax metals, vulcanite and many types of plastics have been used as rigid materials while flexible ones like gelatin glycerine mixtures, latex and elastic plastics have also found some usefulness.2 Presently, materials used for the maxillofacial prosthesis are vinyl plastics, polyurethane, silicone rubber and acrylic types.

Geriatric patients (GP) have been on a rise in the past few decades. It is very essential to assess the nutritional status (NS) of such patients for constant care and support. So the aim of this bibliometric analysis was to provide a summary of countries, universities, authors, journals, and research data related to nutritional status in geriatric patients. Methodology: Many studies related to nutritional status (NS) in geriatric patients (GP) have been published in PubMed indexed journals from 2011 to 2021. Data was extracted from the Science Citation Index expanded core database. Publication of authors, journals, universities, and countries were retrieved and quantitatively analyzed using the R-Studio biblioshiny package.The core data set included a total of 43 Journals and books. 195 documents were recognized. Top 20 PubMed indexed journals were selected which published the data regarding NS. 20 universities were also analyzed for NS in GP. Average years from publication are 4.57 years. Results: A total of 195 documents were extracted. Documents were derived from 2011-2021. The number of documents/publications research steadily increased from 2011 to 2013. Then there was a fall in number of papers and research articles. Over the time, from 2015 till 2017, publications have steeply increased from all over the world. Again there was a gradual decrease in the articles from 2017-2021.

Background: Cranioplasty is considered an essential step for restoring defects in the skull, generally due to the esthetic appearance, safety of the brain, or handling the adverse effect of the Trephined Syndrome (TS) or sinking skin flap syndrome. Moreover, many studies saw the unexpected enhancement of cognitive and motor function after cranioplasty. These favorable progressive effects can be helpful in further therapy preparations in association with cranioplasty effects. Nevertheless, the proof is mainly restricted to case studies that do not target comparison between different materials in post-traumatic brain injury (P-TBI) people even though it is helpful but not enough. Objectives: To comparatively evaluate the effect of cranioplasty using autologous bone graft, polymethylmethacrylate (PMMA), titanium, and bone cement on cognitive and functional improvement in patients with P-TBI. Methodology: 40 subjects will be allocated into four groups. Group A (10 using Autologous bone graft) Group B (10 using PMMA), Group C (10 using Titanium), and Group D (10 using Bone cement). Glasgow Coma Scale (GCS) and Mini-Mental State Examination (MMSE) will be used for cognitive improvement. For functional improvement, Muscle power and Barthel index will be used. The data will be compared before and after cranioplasty. Expected Results: Cognitive and functional improvement will be present after cranioplasty. But the effect of cranioplasty using autologous bone graft, polymethylmethacrylate (PMMA), titanium, and bone cement has to be evaluated & compared to assess the patient’s cognitive and functional improvement and provide desired intervention as required. Conclusion: This study will comparatively evaluate the effect of cranioplasty using different prosthetic materials and determine which material is better for patients' cognitive and functional improvement.
