Surgical emphysema is well known and many case reports have been published on this. Many authors have reported this as a complication post dentoalveolar treatment. Diffusion of air into facial planes and periorbital area during endodontic procedures has been rarely reported. The use of three way air syringe and forceful irrigation of root canal can lead to surgical emphysema of subcutaneous tissue planes in and around the teeth which are involved. This case report highlights one such complication seen during endodontic treatment, discusses aetiology, complications and conservative management of this dental office emergency.
Ameloblastoma is a locally aggressive common odontogenic tumor of the jaws. Although histopathological and radiological findings have been extensively studied for the diagnosis of ameloblastoma, usefulness of fine-needle aspiration cytology (FNAC) has not been explored much. Here, we have reported four cases of ameloblastomas diagnosed by FNAC and subsequently confirmed by histopathology.
Candida is a commensal yeast. It can be infective when the host’s defense mechanism is weakened, as in the case of squamous cell carcinoma patients. We aimed to evaluate the prevalence and clinical mycological manifestation of candidiasis in 150 cancer cases comprised of preoperative and post-operative (with or without radiotherapy) upper aerodigestive squamous cell carcinoma. A total of 150 patients suffering from squamous cell carcinoma of the Upper Aero-Digestive Tract (UADT) were divided into preoperative (n = 48), post-operative without radiotherapy (n = 29) and post-operative with radiotherapy (n = 73). Samples were collected using cotton swabs and cultured. Candida species were identified according to color pigmentation on Candida Differential Agar (CDA) plate. The clinico-mycological association of patients was evaluated by the chi-square test, and 98 out of 150 patients showed the presence of various Candida species. The major species isolated was Candida albicans (53%), followed by Candida tropicalis (16%). There was a significant statistical difference between patients who showed mycological associations and patients who did not have any such association (p = 0.0008). The prevalence of oral candidiasis was found to be 65.33% among total cases of upper aero-digestive squamous cell carcinoma. Chronic erythematous cases of candidiasis were mainly seen in preoperative squamous cell carcinoma cases, whereas the acute erythematous type of candidiasis was mainly seen in post-operative cases who received radiotherapy. The clinicomycological assessment can help to correlate the signs and symptoms with the presence of candidiasis in upper aerodigestive squamous cell carcinoma patients. Meticulous testing and examination can help in the early detection of candidiasis. Future studies are needed to develop advance scientific preventive strategies for high-risk cases.
Background: Salivary pH plays a significant role in the pathogenesis of various oral diseases and conditions. Chewing of areca nut and various tobacco products changes salivary pH. Aim: The aim of the study was to measure the effect of habitual chewing of areca nut and various tobacco products on salivary pH. Materials and Methods: The present study included 360 individuals (chewers and nonchewers) of age group between 20 and 30 years who visited the Outpatient Department of Hi-Tech Dental College and Hospital. The patient's salivary pH was measured with the help of a digital pH meter before and after chewing areca nut and various tobacco products. Results: It was observed that, in all the groups of chewers, pH decreased after chewing except in the gutkha and lime chewing group, where pH increased (pH before chewing was 7.43 ± 0.41 and after chewing was 7.51 ± 0.399), the difference was strongly significant ( P < 0.001). pH was found to be less in lime and tobacco chewers (6.83 ± 0.33) and more in tobacco, betel nut, and lime chewers (7.50 ± 0.41) in comparison to other groups before chewing; the difference was strongly significant ( P < 0.001). In the mean ± standard deviation, increase in pH was found among chewers (7.32 ± 0.49) as compared to nonchewers (6.99 ± 0.14), which is the control group, and the data were statically significant ( P < 0.001). Conclusion: pH is altered in areca nut and various tobacco chewers, rendering the oral mucosa vulnerable to the toxic effects of areca nut and various tobacco products.
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.
