Abstract
When considering deaf and hard of hearing (DHH) population, research recognizes that fatigue due to communication challenges and multi-focal attention allocation is a significant concern. Given the putative heightened demands of distance learning on deaf and hard of hearing students, we investigate how an online environment might differently affect deaf and hard of hearing participants, compared to hearing participants, Portuguese Sign Language (PSL) users and non-users. Our findings show that the deaf and hard of hearing group present higher values in the post-task fatigue rates with significant differences from the hearing group (non-PSL users). Furthermore, our results revealed an association between post-task fatigue rates and lower performance scores for the deaf and hard of hearing group, and the gap is significantly bigger when compared with the hearing group (non-PSL users). We also found evidence for high levels of post-task fatigue and lower performance scores in the hearing group PSL users. These novel data contribute to the discussion concerning of the pros and cons of digital migration and help redesign more accessible and equitable methodologies and approaches, especially in the DHH educational field, ultimately supporting policymakers in redefining optimal learning strategies.

Sivaramakrishnan G, Sridharan K. Effect of clonidine on the efficacy of lignocaine local anesthesia in dentistry: A systematic review and meta-analysis of randomized, controlled trials. JOURNAL OF INVESTIGATIVE AND CLINICAL DENTISTRY 2018; 9:e12296. [PMID: 28944594 DOI: 10.1111/jicd.12296] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2017] [Accepted: 07/23/2017] [Indexed: 06/07/2023]
Abstract
Alternatives to adrenaline with lignocaine local anesthesia, such as clonidine, have been trialed in various randomized, controlled trials. Therefore, the aim of the present systematic review was to compile the available evidence on using clonidine with lignocaine for dental anesthesia. Electronic databases were searched for eligible studies. A data-extraction form was created, extracted data were analyzed using non-Cochrane mode in RevMan 5.3 software. Heterogeneity between the studies were assessed using the forest plot, I2 statistics (where >50% was considered to have moderate-to-severe heterogeneity), and χ2 -test. Random-effects models were used because of moderate heterogeneity. Five studies were included for the final review. While clonidine was found to significantly shorten the onset of local anesthesia when measured subjectively, no significant difference was observed objectively. No significant difference was observed in the duration and postoperative analgesia. Stable hemodynamic parameters within the safe range were observed postoperatively when clonidine was used. Clonidine could be considered as an alternative to adrenaline in cases of contraindications to adrenaline, such as like cardiac abnormalities, hypertension, and diabetes.

Fluoride varnish versus glutaraldehyde for hypersensitive teeth: a randomized controlled trial, meta-analysis and trial sequential analysis. Clin Oral Investig 2018; 23:209-220. [PMID: 29610982 DOI: 10.1007/s00784-018-2428-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2017] [Accepted: 03/19/2018] [Indexed: 01/27/2023]
Abstract
OBJECTIVE Reports indicate Gluma and Duraphat are commonly used in-office agents to treat hypersensitive teeth. Considering this, the aim of this paper is to compare Gluma and Duraphat using a randomized controlled trial, meta-analysis collating evidences from previous studies and trial sequential analysis. MATERIALS AND METHODS Thirty-eight participants were randomized. Hypersensitivity and visual analog scale (VAS) scores were recorded at baseline, 5 min and 7 days. Oral health-related quality of life (OHIP) questionnaire was administered at baseline and 7 days. Statistical analysis was performed to identify significant differences between the variables. For the meta-analysis, electronic data bases were searched and eligible data was extracted and analysed using RevMan 5.0. Trial sequential analysis was performed using O'Brien-Fleming boundary approach for the primary outcome. RESULTS Both agents caused significant reduction in hypersensitivity and VAS score at 5 min and 7 days in the randomized trial with no superiority. The quality of life significantly improved in patients treated with both the agents. Four studies including the present trial in meta-analysis and trial sequential analysis indicated that Gluma produced significant reduction in VAS scores at 7 days. CONCLUSION Gluma produces significant reduction in hypersensitivity at 7 days post treatment compared with Duraphat. There is definite lack of evidence on the long-term effect of these agents. CLINICAL RELEVANCE This paper provides strong evidence on the use of Gluma for hypersensitive teeth. This also is a way forward to future research on long-term effects, adverse effects and cost-effectiveness studies.

Rogus-Pulia NM, Gangnon R, Kind A, Connor NP, Asthana S. A Pilot Study of Perceived Mouth Dryness, Perceived Swallowing Effort, and Saliva Substitute Effects in Healthy Adults Across the Age Range. Dysphagia 2017; 33:200-205. [PMID: 28879557 DOI: 10.1007/s00455-017-9846-7] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Accepted: 08/22/2017] [Indexed: 11/29/2022]
Abstract
Xerostomia, or perceived mouth dryness, increases with advancing age, but its influence on swallowing effort is unknown. This study: (1) quantified relationships among age, perceived sense of swallowing effort, and ratings of perceived mouth dryness, and (2) examined changes in swallowing effort following application of a gel-based saliva substitute in healthy participants. This was a cross-sectional observational study and data were collected from attendees of a community healthy aging fair. Forty-two healthy participants (mean age = 65 years; 20 female) were enrolled. Each participant rated perceived effort with swallowing and perceived mouth dryness on a 10-cm horizontal, undifferentiated line. After participants applied a gel-based saliva substitute (Biotene® Oral Balance) to their tongue and oral mucosa, they rated perceived effort with swallowing again. Age was associated with greater perceived mouth dryness (r = 0.37, p < 0.03) but not with perceived swallowing effort (r = 0.16, p = 0.32). Perceived mouth dryness was associated with greater perceived swallowing effort (r = 0.62, p < 0.001). Perceived swallowing effort declined following application of the salivary substitute (mean difference = 9.39 mm, p < 0.002). Age was found to be a significant predictor of perceived mouth dryness (p < .02); and perceived mouth dryness was found to significantly predict perceived swallow effort (p < .001). Perceived mouth dryness increased with advancing age, but perceived swallowing effort did not. Regardless of age, participants with higher levels of perceived mouth dryness also reported more perceived effort with swallowing suggesting a role for adequate oral lubrication in this perception. Even in healthy participants, use of a gel-based saliva substitute lowered perceived swallowing effort.
