AbstractPurpose Hand function plays a major role in the successful performance of activities of daily living (ADLs), such as eating. There is a lack of data exploring how persons with hand impairment manage food packaging and its impact on eating.Methods A convenience sample of 12 inpatients with hand impairments undergoing rehabilitation participated in a qualitative interview where they were asked questions about their experiences with food packaging and independent eating, and asked to open a set of commonly available hospital food packages, first without any tools/aids, and then with tools/aids if they desired to use them. Audio data were transcribed and cross-referenced with video data. Data were analyzed using codebook thematic analysis.Results An overarching theme of "Messiness" along with four major themes were identified: a) Inaccessibility of food packaging; b) Lack of control; c) Eating avoidance; and d) Preferred packaging and strategies.Conclusions Inpatients with a hand impairment often experience several challenges with independent eating while in hospital as a result of their difficulties with hard to open food packaging. A greater consideration of universal design principles may be relevant for designers to make packaging more accessible.IMPLICATIONS FOR REHABILITATIONInaccessible food packaging may lead to psychological distress in patients with hand impairments, which can involve avoidance of eating.Food packaging that is large, lightweight and that has clear tabs or markers for pulling or tearing are better suited for patients with functional hand impairments.The use of a non-slip mat and/or tool with a sharp end might be useful aids to help patients be more independent with opening food packages while in hospital.Keywords: Hand impairmentfood packagingaccessible packagingactivities of daily livingqualitative analysis Disclosure statementAll authors declare no conflict of interests.Additional informationFundingThis project was completed as part of Susan Wang and Candice Tay's second year research project for the completion of their Masters of Science in Occupational Science and Occupational Therapy.

Sodium hypochlorite is an effective irrigant for chemical debridement of root canals. However, increasing the intracanal pressure during irrigant delivery may result in irrigant extrusion into the bone and soft tissues surrounding the tooth. Because clinicians often encounter teeth with intracanal communications, the objective of the present study was to examine the effects of canal anastomosis on the generation of periapical fluid pressure at different fluid flow rates and insertion depths. Two similar polycarbonate models were used to simulate a single root with double canals, one containing, and the other without communicating channels between the canals. For both models, periapical pressure increased with increasing irrigant flow rates and insertion depths of a 30-gauge side-venting needle. In the presence of communicating channels, the magnitude of pressure build-up decreased by almost 90% irrespective of the fluid flow rate or needle insertion depth. Pressure reduction in anastomoses-containing roots provides an explanation why pressure generation in single roots is considerably higher. Nevertheless, it is still possible in teeth with canal anastomoses for pressure exceeding the intraosseous pressure to be generated when the fluid flow rate is sufficiently high and when the needle tip is close to the apical terminus.
