Nutrient canals (NCs) are passages containing neurovascular bundles (blood vessels, lymph vessels, and nerves). Best visualized on mandibular anterior intraoral periapical radiographs (IOPAR), their presence is usually associated with underlying pathological such as diabetes mellitus (DM), hypertension (HTN), advanced periodontitis, calcium deficiency, tuberculosis, and disuse atrophy. This study aimed to (a) evaluate NC prevalence in patients with DM, HTN, and chronic periodontitis and (b) correlate the detection of NCs as an important preliminary screening tool for inherent systemic diseases like DM, HTN, and chronic periodontitis and as an investigative clue in age and gender determination. This cross-sectional study was conducted on 200 subjects. Patients with complaints of pain in the mandibular anterior teeth, deep dentinal caries, abrasion, and attrition were subjected to IOPAR of the mandibular anterior teeth region to assess NCs. An increased frequency of NCs in DM (84%), HTN (66%), and periodontitis (52%) with a significant p-value was observed. Most NCs were seen beyond the root apex (72.4%). A notable association between the duration of disease and the presence of NCs in the diabetic and hypertensive cohorts (p-value 0.047 & 0.012, respectively) was observed. However, we could not establish any association between the prevalence of nutrient canals with age and gender. Our study suggested that a higher frequency of NCs on mandibular anterior IOPAR may be employed as an ancillary screening and investigative support in underlying systemic disorders., (© 2022 JOURNAL of MEDICINE and LIFE.)

Over the years, chemotherapy (CT) has evolved as an essential therapeutic modality for cancer, with oral manifestations frequently encountered as complications of cancer CT. Our study aimed to assess the prevalence of oral complications during CT and evaluate the significance of independent risk factors (age, gender, socio-economic status, oral hygiene practices etc). A cross-sectional study was carried out in a tertiary cancer hospital in Bhubaneswar, Odisha, India, in which a total of 138 hospitalized patients undergoing CT and fulfilling the inclusion and exclusion criteria were included. Comprehensive history and rigorous clinical examination eliciting the oral manifestations were carried out. Around 60% of patients exhibited oral manifestations. Xerostomia and lichenoid reactions were the highest and lowest recorded manifestations. Higher frequencies of oral lesions occurred in patients with breast cancer, TNM stage III, and with the administration of the docetaxel. Also, patients in the older age group, poor socio-economic status, poor quality of life, poor oral hygiene practices, and longer CT duration demonstrated more oral lesions. Individuals subjected to a dental evaluation either before or during CT exhibited a reduction in the number of oral features. Several oral complications were reported in the present study. All patients undergoing chemotherapy must receive reinforcement of oral hygiene instructions and dental evaluation before, during, and after chemotherapy treatment. The study also emphasizes the importance of oral health physician inclusion in the multidisciplinary cancer treatment team., (©2022 JOURNAL of MEDICINE and LIFE.)

The recent outbreak of coronavirus disease 2019 (COVID-19) is the worst global crisis after World War II. Since the vaccine trials are still ongoing, the national lockdowns have been the most effective way to contain its spread. The pandemic has been extremely stressful and full of anxiety for those with comorbidities as they are the most vulnerable to the COVID-19 infections. Various efforts to assess and enhance the knowledge, attitudes, and practice, especially the high-risk groups, are critical to managing the COVID-19 pandemic successfully. A cross-sectional online survey was carried out using a self-designed questionnaire. A total of 383 participants who were 30 years or older, with at least one comorbidity, were included in the study. The mean age of the participants was 50.63±11.83 years. The most common comorbidities among the included participants were hypertension, followed by diabetes mellitus and thyroid disorders (48.5%, 44.7% and 23.3%, respectively). Our study also showed the education (p=0.004) and occupation (p=0.04) had a significant association with the attitude and practices towards the COVID-19 pandemic. In conclusion, our study showed that a high level of knowledge, attitude, and practices are the backbone to combat a global crisis like COVID-19., (©2021 JOURNAL of MEDICINE and LIFE.)

Temporomandibular joint disorders (TMDs) encompass a wide array of ailments affecting the temporomandibular joint (TMJ), muscles of mastication, and the allied structural framework. Myofascial pain, internal derangement of the joint, and degenerative joint diseases constitute the majority of TMDs. TMDs usually have a multifactorial etiology, and treatment modalities range from conservative therapies to surgical interventions. Low-level laser therapy (LLLT) has evolved as an efficient non-invasive therapeutic modality in TMDs. Previously conducted systematic reviews and meta-analyses have shown variable results regarding the efficiency of LLLT in TMJ disorder patients. Hence, this systematic review was carried out as an attempt to evaluate the efficacy of LLLT in the treatment of temporomandibular joint disorder patients., (©2021 JOURNAL of MEDICINE and LIFE.)
