Similarities and differences between kaiy in Persian medicine and moxibustion in Chinese medicine.

Kaiy (medieval cautery) is an ancient method of heat therapy in traditional Persian medicine (TPM). Some of its important applications have been neglected during the medical revolution. Meanwhile, different treatment modalities that incorporate heat, including moxibustion, have progressed in traditional Chinese medicine. In this study, we reviewed the main TPM textbooks that were written specifically in the field of kaiy. We considered the traditional teachings in the context of contemporary information, gathered from the scientific literature about moxibustion and modern cauterization. Some surgical therapeutic indications of kaiy (e.g., debridement and coagulative procedures) have been advanced by the innovation of electro-cauterization. However, those therapeutic applications that were based on the TPM humoral theory for relieving body coldness or myofascial pains-which are similar to moxibustion usages-have not received the same attention. Apart from the broad similarities of kaiy and moxibustion as thermal therapies with similar indications, there is a striking correspondence between kaiy point mapping and acupoints. Therefore, further research on different kaiy aspects is recommended. Please cite this article as: Jaladat AM, Alizadeh Vaghasloo M, Atarzadeh F, Ayati MH, Kazemi AH, Akin E, Hashempur MH.

Investigation of the Presence of SARS-CoV-2 in Aerosol After Dental Treatment.

AIMS: The objective of the present study was to investigate the presence of SARS-CoV-2 in aerosol and COVID-19 contamination distance asssociated with ultrasonic scaling and tooth preparation. METHODS: Twenty-four patients with COVID-19 were included in this study. Removal of supragingival plaque with ultrasonic instruments for 10 minutes and high-speed air-turbine using for the simulation of cutting the maxillary right canine tooth with a round diamond bur for 5 minutes were performed. Patients were randomly assigned to 2 groups: In group A, medium-volume suction was used during treatment. In group B, high-volume suction with an aerosol cannula was added to medium-volume suction. Prior to treatment, 5 glass petri dishes containing viral transport medium were placed in the operating room. After treatment, petri dishes were immediately delivered to a microbiology laboratory for real-time polymerase chain reaction (RT-PCR) analysis. RESULTS: RT-PCR test results were negative for all specimens in group B. However, 5 positive test results for COVID-19 were detected in group A specimens. CONCLUSIONS: Suction with an aerosol cannula is very important to prevent COVID-19 viral contamination via aerosol. In addition, a high-volume suction capacity (air volume) of 150 mm Hg or 325 L/min is sufficient for elimination of viral contamination. Thus, high-volume suction should be used during dental treatments in COVID-19 patients.

Evaluation of a self-adhering flowable composite in terms of micro-shear bond strength and microleakage.

PURPOSE: The objective of this study was to evaluate dentin bond strength and microleakage of a self-adhering flowable resin with or without adhesive resin. MATERIALS AND METHODS: Dentin pieces were randomly assigned to three groups (n = 10): Group OR (Optibond+Revolution Formula 2 Flow); Group VF (Vertise Flow); and Group OVF (Optibond+Vertise Flow). Then specimens were stressed in shear at a cross-head speed of 1 mm/min until the bond failed. Moreover, microleakage was determined by restoring Class V cavities. A statistical analyses was carried out using Mann-Whitney U and Kruskal-Wallis tests (p < 0.05). RESULTS: Group OVF specimens produced the highest mean shear bond strength. In addition, the results showed that the marginal seal in group VF was similar to that in group OR. CONCLUSION: Self-adhering flowable composite resin combined with adhesive resin provided stronger dentin bond strength and a better marginal seal than when it was used individually. VF is a useful material with an acceptable bond strength and marginal seal.

Multidisciplinary approach for esthetic, functional, and quality-of-life outcome in soft palate cleft patient.

The fabrication of a Suersen obturator prosthesis with titanium framework is described in the case of a 43-year-old man with congenital absence of the soft palate. The patient revealed an open soft palate, bilateral cleft lip and palate, Angle Class III dental malocclusion, and anterior and posterior crossbite. He was treated with a multidisciplinary approach. A Dolder bar was fabricated between the maxillary canines, and telescopic crowns were prepared for maxillary premolars. Angle Class III tooth relation was readjusted to tooth-tooth relation; closure of the nasopharynx and oropharynx was performed by Suersen method, which improves speech.
