Bhatnagar P, Gupta I, Trivedi A, Kusum CK, Saxena D, Kaur J
Abstract
Aim:
The purpose of this survey was to find the attitude and practice of impression disinfection protocol employed by the practicing dentists in their clinical practice in Tamil Nadu.
Materials and Methods:
Self-administered validated online website based questionnaires were circulated among dentists practicing in Tamil Nadu. The questions were taken up by dentists who were willing to participate in the survey and a total of 200 responses were recorded. There were two sections to the questionnaire: one included demographic information and the other featured questions regarding the disinfection protocol. The responses were recorded in excel sheet followed by statistical analysis of the data.
Results:
97.5% of the dentists routinely rinse the impression with running tap water before sending it to the lab/ prior pouring the cast and 2.5% dentists do not rinse the impressions. 78.9% dentists routinely disinfect the working impressions, whereas 21.1% do not disinfect the working impressions before sending it to the laboratory/ before pouring the casts. 48.2% of the dentists stated that they are unsure whether their lab workers disinfect their preliminary/working impression before pouring casts. 46.9% dentists stated that they do not have disinfection guidelines in their clinic. 81.4% believe that covid-19 spreads by saliva and 73.9% dentists have changed the disinfection protocol for impressions after covid-19.
Conclusion:
It was found that the majority of respondents rinsed and disinfected the impression with running water and disinfected it on a regular basis for 1-10 minutes. This study also indicates a lack of interaction between the dentists and dental technicians about the information on the disinfection status of the impression sent, as well as a need for increased awareness in order to reduce the disease transmission in dental laboratories. Significant number of dentists have changed their disinfection protocol after covid-19 pandemic.

Pradhan A, Karmakar S, Bhattacharyya J, Das S, Ghosh S, Maji S.
Abstract
Technology has had an increasing impact on every facet of life and society. It has made almost every aspect of our lives easier, more productive, and delightful. Various aspects of technology are transforming dentistry for the better, Artificial Intelligence (AI) is one of them. It describes how technology develops software or a machine that can easily mimic human intelligence and perform specific activities. Nowadays, AI is gaining popularity because health science has adopted this dynamic technology. It executes various services precisely and saves time and money. AI is slowly digging its head in the sector of Prosthodontics and will continue to do so. It has shown the potential for providing a reliable diagnostic tool for tooth shade selection, automated restoration design, mapping the tooth preparation finishing line, but they are still in development. It is also helpful in patient documentation, diagnosis, patient management, health monitoring, robotic tooth preparation, and implant planning. So, the advancement of computer technology has introduced AI in health science that mimics human intelligence to accomplish miscellaneous work. So, applications of AI are widespread. In the recent pandemic, the COVID-19 era contribution of AI is ongoing. However, additional studies are needed to develop further and assess their clinical performance.
Keywords: Artificial Intelligence, tooth shade selection, automated restoration design, robotic tooth preparation, implant planning.

Stem cell-based regenerative prosthodontics: A new era in prosthodontics.
Ghoshal N, Pradhan A, Das S, Bhattacharyya J, Ghosh S, Niyogi S.
Abstract
The ultimate goal for tissue engineering and regenerative medicine is to develop therapies to rejuvenate lost or damaged tissue using engineered or regenerated products derived from either donor or autologous cells. Cell-based therapies are widely used in the field of regenerative medicine. Stem cells are undifferentiated or partially differentiated biological cells found in multicellular organisms that can differentiate into specialized cells. Two types of stem cells are present in humans. These are the embryonic and the adult stem cells. Embryonic stem cells are isolated from inner cell mass blastocytes, and adult stem cells are found in various tissues. The dental pulp stem cells are the pluripotent mesenchymal stem cells (MSC), which are the most commonly used. However, bone marrow-derived mesenchymal stem cells are another commonly used cell type in stem cell-based regenerative prosthodontics. They help to rebuild the bone structure of the defects of craniofacial region, particularly the maxilla and mandible. Stem cell therapy is the new horizon in the field of regenerative dentistry.
Keywords: Stem cell, embryonic stem cell, adult stem cell, regenerative prosthodontics.

Retention in maxillofacial prostheses: The ultimate challenge.
Sarkar S, Saha S, Giri TK, Ghosh G, Mukherjee S.
Abstract
The defects in facial regions caused by accident, trauma, tumour or congenital defects are treated with maxillofacial prostheses. Apart from esthetics, the most common problem encountered with these prostheses is the retention of prostheses. Increase in retention provides easy use and psychological acceptance by the patient thereby up the long prognosis of the prosthesis. In this review article, the methods used for the retention of prostheses from past to present along with the benefits of adhesives and implants, implementation of 3D technology and rapid prototyping were critically appraised.
Keywords: Maxillofacial prosthesis, adhesives, retention, implants, rapid prototyping, 3D technology.

Balanced Occlusion – A Myth or Reality.
Saha S, Das S, Niyogi S
Abstract
The search for the ideal denture occlusion in an effort to find out the tooth forms which provides aesthetic, stability, and masticatory efficiency without compromising the health of underlying hard and soft tissues of the edentulous arch has always been elusive. The occlusal contacts between the opposite teeth during centric and eccentric movements of the mandible will be based on the type of occlusal schemes. One such scheme is balanced occlusion. Balance or equilibrium is the condition in which forces act on a body in such a way causing no motion. This should be the principal consideration of the dentist while considering the forces that act on the teeth and the denture bases. A stable base is the ultimate goal. Hence balanced occlusion can be a key to achieve this stability in a myriad of situations. This case report exhibits how bilateral balanced occlusion can be applied in our routine practice.

Combination Syndrome: A case report.
Mandal G, Das S, Ghosh S.
Abstract
Combination syndrome (CS) is a dental condition that is generally seen in patients with a fully edentulous maxilla and partially edentulous mandible with preserved anterior teeth. This syndrome is characterised by presence of anterior maxillary resorption in combination with hypertrophic and atrophic changes in different quadrants of maxilla and mandible. This makes it a grueling condition in dentistry that requires significant experience along with advanced restorative and surgical expertise. Conventional treatment with full upper and partial lower dentures for the CS cases are not always acceptable or satisfying for patients and it frequently requires multiple remakes due to continuing bone resorption. Dental implant rehabilitation challenges conventional treatment with bone-anchoring strategies to provide improved retention and stability for implant-retained and supported prostheses. This case report portrays a successful treatment of the edentulous maxilla and partially edentulous mandible in CS patient. The necessity of an interdisciplinary approach for early prevention and treatment of this complex condition is emphasized.
Keywords: Combination syndrome, resorbed maxilla, flabby tissue, atrophic bone.

Demystifying resorbed ridges- The neutral way.
Chatterjee S, Das S, Niyogi S.
Abstract
One of the most challenging tasks for a prosthodontist is to rehabilitate a patient with severely resorbed ridges with proper retention, stability and support. Stability is an important factor in a denture when retention and support cannot be provided well by the reduced denture bearing areas of the resorbed ridges. Many techniques have been adopted to increase the stability of the denture. The most promising among them is the neutral zone technique which focuses on arranging the teeth in harmony with the stomatognathic system resulting in a stable denture. But not only the position of the teeth but the flanges of the denture also contribute to the stability of the denture which is recorded with the help of cameo surface recording. In this case report, neutral zone technique with cameo surface recording was done to fabricate a denture with severely resorbed mandibular ridge.
Key words: Residual ridge resorption, neutral zone technique, cameo surface recording.

Bhattacharjee S, Das S, Roy S.
Abstract
Rehabilitation of an orbital defect is a challenging task, which requires a multidisciplinary approach. The aesthetic and psychosocial impairment associated with ocular defects may cause significant physical and emotional problems. Various treatment modalities are available such as the conventional ocular prosthesis retained by bony and soft tissue undercuts, implant-supported orbital prosthesis etc. Although implant-supported orbital prosthesis encompasses a superior outcome, it may not be advisable in all patients due to economic factors. The present article describes a simplified technique for the fabrication of an interim customized ocular prosthesis that rehabilitates the patient with ideal fit and aesthetics.
Keywords: Ocular defects, ocular prosthesis.
