Minimally Invasive Transalveolar Sinus Augmentation: An Answer to Sinus Conundrum p. 4
Jaibin George, Saumiya Gopal, Febel Huda, Niti Thomas
DOI:10.4103/dmr.dmr_3_20  
Dental implants have become the routine option for replacement of missing teeth, but it is challenging to place implants in the posterior maxilla due to inadequate bone dimensions and pneumatization of the maxillary sinus. Several techniques have been introduced over the years for sinus augmentation and bone grafting; both lateral and crestal approaches to sinus lift have been used with good results. In recent times, a minimally invasive technique has been used as a modification of crestal approach to sinus augmentation called minimally invasive technique sinus augmentation (MITSA). This method utilizes the calcium phosphosilicate putty for hydraulic sinus membrane elevation along with osseodensification drills. MITSA has simplified the sinus lift technique with predictable good results.

Public health significance of head and neck cancer – A narrative review p. 10
Fatma Ahmed, Sabria Al Marshoudi, Syed Wali Peeran
DOI:10.4103/dmr.dmr_4_20  
Head and neck cancers (HNCs) are a term describing the biologically heterogeneous group of cancers that affect the upper aerodigestive tract and share a common anatomic origin. HNC is one of the most prevalent types of cancers globally. This narrative review is based on a comprehensive search of Medline, Google Scholar, the Cochrane Database of Systematic Reviews, and other electronic databases. The scientific literature in English language dealing with HNCs with relevance to public health significance was reviewed. Various topics of controversy in dealing with the public health significance of HNC have been highlighted in this report in context to the needs of the HNC patients. The search revealed significant gaps in public health delivery for HNC patients. Moreover, conclusively, we recommend that the health-care professionals should be better trained to handle the needs of HNC patients.

Effect of sliding wear mechanism condition on the wear behavior of dental biocomposite materials p. 18
Efe Çetin Yilmaz
DOI:10.4103/dmr.dmr_2_20  
Background: The purpose was to study the effect of sliding condition on the wear behavior of nanofilled composite material under two-body wear test mechanism. Materials and Methods: In this study, a supreme composite material with nanofiller was subjected to abrasion test procedures' in vitro conditions. In this study, the test samples were divided into two groups and subjected 50 N wear force, 1.6 Hz wear frequency, 240,000 wear cycles, constantly 37°C temperature, and 0.3 mm and 0.6 mm sliding conditions through wear test procedures, respectively. The volume loss in the wear area of the test samples after the wear test procedures was analyzed using a noncontact three-dimensional profilometer. In addition, microstructure analysis was performed by selecting random test samples from each group using scanning electron microscopy. Results: As per the data obtained during this study, with an increase in the amount of lateral movement, the volume loss in the composite material had also increased after wear test procedures. Conclusion: However, the increase in volume loss in the wear area of the composite material did not show a linear relationship with the amount of lateral movement.

Assessment of common errors and subjective quality of digital panoramic radiographs in a dental institution p. 23
Nithin Kumar
DOI:10.4103/dmr.dmr_22_19  
Aim: The aim of the study was to determine the incidence of patient preparation and positioning errors during panoramic radiographic imaging and to assess the subjective quality of panoramic radiographs in a sample of records collected from a dental institution. Materials and Methods: The study material was 1000 randomly selected panoramic radiographs obtained from the database of the department of oral and maxillofacial radiology. Patient preparation and positioning errors of the radiographs were evaluated and categorized into nine groups. The sample radiographs were also evaluated for subjective quality according to a three-point quality scale by the National Radiological Protection Board (United Kingdom) as “excellent,” “diagnostically acceptable,” or “unacceptable.” Results: Out of 1000 radiographs evaluated, failure to position the tongue against palate was the most common error at 69.5% and patient movement during radiographic exposure was the least common error at 0.4%. As per the subjective quality ratings, 22.4% of the radiograph had excellent quality, 66.4% were diagnostically acceptable, and 13.2% were unacceptable. Conclusion: The incidence of patient positioning errors in the panoramic radiographs was relatively common. The quality of the diagnostic panoramic radiographs could be improved by better operator education and awareness in relation to patient preparation and positioning.

Dentist's role in maxillofacial prosthetic rehabilitation: Outlook of undergraduate dental students of aimst university: A questionnaire-based study p. 27
Ajay Jain, Sridevi Ugrappa, Jong Fong Hui, Khaw Soon Kai, Min Jing Koay
DOI:10.4103/dmr.dmr_27_19  
Statement of Problem: Anecdotal evidence suggests that there is a lack of literature regarding the awareness of maxillofacial prostheses among dental students. Purpose: This study identifies the level of cognition of undergraduate dental students in various aspects of maxillofacial prosthetic rehabilitation using a questionnaire. Materials and Methods: A total of 180 undergraduate dental students were involved in the study for the analysis of a series of structured questionnaires, related to awareness of dentist's role in maxillofacial prosthetic rehabilitation. Results: The results of the study showed that 90% of the cohort were aware of a maxillofacial prosthesis. About 78% of the cohort had heard of various types of maxillofacial prosthesis. Only 18.3% and 28.9% of the cohort had knowledge that silicone elastomer and acrylic is used in the fabrication of such prosthesis, respectively, but 41.7% were not sure about it. About 80% and 86.1% of the cohort think that maxillofacial prosthetic rehabilitation is an alternative treatment option for plastic reconstructive surgery and maxillofacial prosthetists should be the team member of anaplastology team, respectively. Conclusions: The majority of the students were aware of maxillofacial prosthetic rehabilitation to a certain degree. This survey underlines the need for providing adequate awareness initiatives for dental students to further enhance their knowledge and exposure regarding this field of expertise.
