ABSTRACT
Ozone is utilized in dentistry as ozonated oils, ozonated water, and gaseous ozone. The application of ozone in all specialties of dentistry has been demonstrated to be biocompatible. It has been demonstrated to encourage the remineralization of recently carious teeth, and it is utilized in dental caries and intracanal irrigants in endodontic treatment. Herpes virus infection, avascular osteonecrosis of the jaw, and alveolitis have all been treated with it. It can be applied as a supplement in the surgical and ongoing stages of periodontal disease and also hinders plaque formation. The purpose of the present review article is to discuss the numerous application of ozone in dentistry.
ABSTRACT
Transcutaneous electrical nerve stimulation (TENS) therapy has been accepted to treat a wide range of illnesses, including phantom limb pain, joint pain, low back pain, and cervical discomfort. TENS is not frequently used in dentistry, despite its potential advantages. 3, 4 Therefore, the rationale of present review is to discuss its dental applications in order to spread awareness of them among the dental profession.
ABSTRACT
Introduction: For the complete removal of the intracanal debris and the infectious agents, the intracanal irrigation plays a significant role. Hence, in our study, we assessed the efficiency of diode laser in root canal disinfection. Materials and Methods: We conducted an in vitro study on 45 extracted single noncarious teeth. We equally divided the teeth into controls, Endovac, and diode laser. Later the mean colony-forming units (MCFU) of the Enterococcus faecalis were calculated and compared statistically. Results: We observed that the MCFU in the controls, Endovac, and diode laser was 108/ml, 104/ml, and 0, respectively, after the incubation. Conclusion: We can conclude that diode laser can be successful in irrigation of the root canals.
ABSTRACT
A new artificial intelligence (AI) supported T-Ray imaging system designed and implemented for non-invasive and non-ionizing screening for coronavirus-affected patients. The new system has the potential to replace the standard conventional X-Ray based imaging modality of virus detection. This research article reports the development of solid state room temperature terahertz source for thermograph study. Exposure time and radiation energy are optimized through several real-time experiments. During its incubation period, Coronavirus stays within the cell of the upper respiratory tract and its presence often causes an increased level of blood supply to the virus-affected cells/inter-cellular region that results in a localized increase of water content in those cells & tissues in comparison to its neighbouring normal cells. Under THz-radiation exposure, the incident energy gets absorbed more in virus-affected cells/inter-cellular region and gets heated; thus, the sharp temperature gradient is observed in the corresponding thermograph study. Additionally, structural changes in virus-affected zones make a significant contribution in getting better contrast in thermographs. Considering the effectiveness of the Artificial Intelligence (AI) analysis tool in various medical diagnoses, the authors have employed an explainable AI-assisted methodology to correctly identify and mark the affected pulmonary region for the developed imaging technique and thus validate the model. This AI-enabled non-ionizing THz-thermography method is expected to address the voids in early COVID diagnosis, at the onset of infection.
ABSTRACT
INTRODUCTION: Diabetes is associated with the vascular and the neuronal damage of the eye leading to diabetic retinopathy (DR). The circadian rhythms and also the quality of life (QoL) are known to be impacted by the photosensitive retinal ganglion cells, which are seen to be affected in the DR. Hence, we aim to find a relation between the DR and its impact on the life quality. MATERIALS AND METHODS: Thousand participants were equally divided into two groups of case and controls (DR). The control group was further divided into three subgroups based on the severity of the disease as proliferative and nonproliferative (mild, moderate, and severe). The impact on the QoL was assessed using the Short Form Health Survey-36. The collected data were analyzed for the various grades of the severity of DR on the quality of the life. RESULTS: There was a notable change between the case and the controls and the QoL deteriorated with the severity of the disease. However, these findings were insignificant statistically. CONCLUSION: DR impacts the QoL of the patients, and the severity of the disease is proportional to the worsening of the disease. Further, research is warranted for the association.
ABSTRACT
INTRODUCTION: In oral and maxillofacial surgery, their clinical application has largely been restricted to soft tissue. Hence, the aim of this study was to assess the feasibility of erbium-yttrium aluminum garnet (Er: YAG) laser in bone cutting for removal of impacted lower third molar teeth and to compare its outcomes with that of surgical bur. MATERIALS AND METHODS: The study comprised forty subjects requiring removal of impacted mandibular third molar, randomly categorized into two equal groups of 20 each, who had their impacted third molar removed either using Er: YAG laser or surgical bur as per their group, using standard methodology of extraction of impacted teeth. Clinical parameters such as pain, bleeding, time taken for bone cutting, postoperative swelling, trismus, wound healing, and complications were compared for both groups. RESULTS: Clinical parameters such as pain, bleeding, and swelling were lower in laser group than bur group, although the difference was statistically not significant. However, postoperative swelling showed a significant difference in the two groups. Laser group required almost double the time taken for bone cutting with bur. Trismus persisted for a longer period in laser group. Wound healing and complications were assessed clinically and there was no significant difference in both the groups. CONCLUSION: Based on the results of our study, the possibility of bone cutting using lasers is pursued, the osteotomy is easily performed, and the technique is better suited to minimally invasive surgical procedures. The use of Er: YAG laser may be considered an alternative tool to surgical bur, especially in anxious patients.
