Aims: Though use of transcutaneous electrical nerve stimulation (TENS) in dentistry was first described in 1967 by Shane and Kessler, it has yet to gain widespread acceptance in dentistry. This study was designed to evaluate and compare the effectiveness of active and placebo TENS therapies in the treatment of temporomandibular disorder.Methods: Thirty patients received active TENS therapy and 15 received placebo TENS therapy. VAS was used to measure changes in pain and tenderness in the muscles of mastication and TMJs during and after therapy. Also, changes in mouth opening was recorded and analyzed.Results: A significant improvement was observed in both active and placebo TENS therapies regarding orofacial pain, muscles and TMJs tenderness and interincisal distance. None of the parameters except medial pterygoid muscle tenderness revealed any differences between the methods. Conclusion:This study justifies the use of TENS therapy as well as placebo in the management of TMD. TENS therapy appears to be useful in relieving pain, especially muscular and chronic pain. Hence, along with TENS therapy, placebo should also be considered as a potent and independent therapeutic modality in its own right.
There was gradual but significant reduction in Candidal CFU count in both groups. At the end of the treatment, Candidal CFU count reduction in ozone group (60.5% reduction) was more than the clotrimazole group (32.3% reduction). 14 patients (70%) with candidiasis in ozone group were reduced to 6 (30%) whereas only 8 patients (40%) out of 13 (65%) in clotrimazole group, although intergroup comparison was not statistically significant. Ozone therapy was much more effective in reducing the patients with candidiasis to a state of carriers. These findings suggest that ozonated water might be useful to treat oral candidiasis.
Background:Ionizing radiation is a potent mutagenic agent capable of inducing both mutation and chromosomal aberrations. Non-lethal doses of ionizing radiation may induce genomic instability favoring carcinogenesis. In spite of their mutagenic potential, this kind of radiation is an important tool for diagnosis of the disease and is used in medical and dental practice. It has been believed that the number of micronucleus and increased frequency of other nuclear alterations, including karyorrhexis, condensed chromatin and pyknosis, are related to the increasing effects of carcinogens. Many approaches and techniques have been developed for the monitoring of human populations exposed to various mutagens, but the analysis of micronuclei (MN) has become a standard approach for the assessment of chromosomal damage in human populations.Aim:To assess the effects of radiation exposure from panoramic radiography on the buccal epithelial cells (BECs) of pediatric patients.Materials and Methods:The study included 20 pediatric patients who had to undergo panoramic radiography for further dental treatment. Exfoliated BECs were obtained and examined immediately before and 10 days after radiation exposure. The cells were stained using rapid Papanicolaou (PAP) kit. Evaluation for MN and nuclear alterations was carried out by an oral pathologist and data were statistically analyzed using the “t” test.Results:The mean number of MN in the BECs before exposure of pediatric patients to panoramic radiography was 4.25 and after exposure was 4.40. This difference was not found to be statistically significant (P < 0.0001). However, the mean nuclear alterations of 8.70 and 15.75 before and after exposure were statistically significant (P < 0.0001).Conclusion:Panoramic radiographs can induce cytotoxicity but not genotoxic effects in buccal mucosal cells. Hence, dental radiographs should be prescribed only when deemed indispensable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
