RESUMEN
Important counter measures to combat an infectious disease pandemic include vaccination, antiviral therapy, and immunomodulation therapy. Vaccinations are disease specific and moreover strain specific, so the protection provided is also specific and limited. Antiviral therapies are costly and require bulk production of drugs, hence globally there is an increased interest toward low-risk, cost-effective complementary alternative therapies, such as Yoga and Ayurveda to tackle the infectious pandemic, coronavirus disease 2019 (COVID-19). There is clinical evidence available on the potential complementary role of yogic practices in the management of noncommunicable and communicable diseases. Various online databases were searched for articles published between 2000 and 2020. Databases explored were Medline, EMBASE, Indian Citation Index, PsycINFO, Index Medicus for South-East Asia Region, and Google Scholar. All search results were screened, and articles related to keywords such as COVID-19, yoga therapy, and Sudarshan Kriya Yoga (SKY) were selected for data extraction. Quality of the studies included was evaluated on the basis of the construct validity, content validity, relevance, bias, credibility relating to information, and data sources. SKY is a unique yogic practice that includes specific sequential breathing techniques. It balances the autonomic nervous system and thus can alleviate anxiety, routine stress, depression, stress-related medical disorders, and posttraumatic stress. It potentiates natural host immune defenses that are essential to tackle a plethora of microbial infections. This narrative review article provides an overview of potential therapeutic benefits that SKY can offer to the population at large during this COVID-19 pandemic.
RESUMEN
BACKGROUND: Periodontitis and osteoporosis are two diseases found worldwide and increase in intensity with increasing age of the patients. The severity of osteoporosis and periodontitis are found to be more in women during menopause. The aim of this study was to assess and correlate osteoporosis and periodontal disease among post-menopausal women. MATERIALS AND METHODS: The study consisted of 94 postmenopausal women in the age range of 45-65 years. All the women underwent dual-energy X-ray absorptiometry (DXA) scan to measure bone mineral density (BMD) and were graded as normal, osteopenic, and osteoporotic based on the T score obtained. Data regarding patient's educational level, socioeconomic status (SES), and body mass index (BMI) was recorded. A detailed periodontal examination was carried out using clinical parameters such as oral hygiene index (OHI), plaque Index (PI), probing pocket depth , and clinical attachment loss to check the level of periodontitis. The level of osteoporosis was correlated with the level of periodontitis. RESULTS: The DXA scan revealed that four women were normal, 44 were osteopenic and 46 were osteoporotic. There was no association found between BMD and OHI, PI, educational status, SES, and BMI. Slight periodontitis was observed in eight women, moderate periodontitis in 62, and severe periodontitis in 24 women. Result suggests that there was a statistical correlation between periodontitis and osteoporosis (P = 0.045). CONCLUSION: There is a definite correlation found between the severity of periodontitis and osteoporosis among postmenopausal women. A close cooperation between general practitioners and dentists in early diagnosis and treatment of both the diseases will reduce the risk and morbidity among postmenopausal women.
RESUMEN
INTRODUCTION: Clinical and aesthetic outcomes after periodontal or implant surgical procedures are determined by anatomical and morphological characteristics of the gingiva like width of keratinized gingiva, thickness of gingiva and alveolar bone. Therefore, the knowledge of gingival biotype plays an important role in modifying the dental therapeutic procedures for the desired outcome and predictability. AIM: The aim of the present study was to assess and compare the gingival biotype among genders by clinical, photographic and radiographic parameters. MATERIALS AND METHODS: A total of 800 subjects (400 males and 400 females) were considered for the study. Width of keratinized gingiva (GW), transparency of the periodontal probe through the sulcus (TRAN) were assessed clinically; Crown Width/Crown Length ratio (CW/CL) and Papillary Height (PH) were assessed photographically; Gingival Thickness (GT1, GT2, GT3) and Alveolar bone Thickness (AT1, AT2, AT3) were assessed radiographically. The obtained data was correlated to compare the gingival biotype between males and females. The collected data was statistically analysed using Pearson correlation coefficient (r) with the corresponding 95% confidence interval. RESULTS: The TRAN at GT1, GT2 and GT3 as well as at AT1, AT2 and AT3 showed a very strong positive correlation in males (r>0.8) as compared to females (r<0.8). A very strong positive correlation was observed between GT1, GT2, GT3 and AT1, AT2, AT3 in males (r>0.9) as compared to females (r<0.7). CONCLUSION: There are definite differences in the gingival biotype among different genders with predominance of a thin gingival biotype with reduced alveolar bone thickness in females as compared to males.
RESUMEN
INTRODUCTION: Dentinal Hypersensitivity (DH) is one of the most commonly encountered clinical problems. Literature reveals no specific therapy to satisfactorily eliminate dentinal hypersensitivity. AIM: The aim of this study was to assess and compare the efficacy of iontophoresis with 0.33% Sodium Fluoride (NaF) gel and diode laser alone in dentinal tubule occlusion. MATERIALS AND METHODS: This in vitro study included 20 teeth with intact root surfaces unaltered by extraction procedure for specimen preparation. Each tooth was cleaned, air dried and cut into three sections. Total 60 sections were prepared (30 longitudinal and 30 transverse sections), which were acid etched. In control group, no treatment was carried. In iontophoresis treatment group, samples were inserted into a foam tray containing 0.33 % NaF Gel and subjected to 1.5 mA output current for three minutes. In laser treatment group, specimens were lased with 980 nm diode laser at 0.5 W/PW (62.2J /cm2) in a noncontact mode for 30 seconds. Specimens were evaluated under Scanning Electron Microscope (SEM) at 10KV to 20KV under x 2000, x5000 magnification for surface characteristics and patency of dentinal tubules. Total number of tubules visible, open, completely and partially occluded were recorded in each microphotograph and compared. RESULTS: On comparison, laser group showed the least number of open tubules i.e., 130 (31.1%) followed by iontophoresis group, 155 (51.32%) and control group 417 (100%). CONCLUSION: Diode laser application provided better results as compared to iontophoresis on occlusion of dentinal tubules. Hence, it can be used to treat the patients with DH.
RESUMEN
Periodontitis is a disease of the periodontium, characterized by loss of connective tissue attachment and supporting the alveolar bone. Therefore, to regenerate these lost tissues of the periodontium researchers have included a variety of surgical procedures including grafting materials growth factors and the use of barrier membranes, ultimately resulting into regeneration that is biologically possible but clinically unpredictable. Recently a newer approach of delivering DNA plasmids as therapeutic agents is gaining special attention and is called gene delivery method. Gene therapy being considered a novel approach have a potential to channel their signals in a very systematic and controlled manner thereby providing encoded proteins at all stages of tissue regeneration. The aim of this review was to enlighten a view on the application involving gene delivery and tissue engineering in periodontal regeneration.
