The Development of an Authentic Professional Identity on Role-Emerging Placements
Authors: Clarke Channine , Martin Marion , Sadlo Gaynor , de-Visser Richard 
Published: May 2014

Introduction: Role-emerging placements are increasingly used to help occupational therapy students develop the skills, knowledge, and attributes needed to become the therapists of tomorrow. Whilst literature on role-emerging placements is growing, studies have tended to be general placement evaluations, with only a limited number exploring students' experiences in detail. Method: This study used interpretative phenomenological analysis to gain a deeper understanding of how five MSc pre-registration occupational therapy students experienced and ascribed meaning to their role-emerging placements. Findings: The role-emerging placements acted as a strong catalyst for the students' ontological development (that is, their understanding of self and development of ways of being and enacting occupational therapy practice). Through engaging in challenging and autonomous learning experiences, students developed deeper insights into who they were becoming as professionals, leading to a professional identity of their own making. Conclusion: Having to continually reflect on and verbalize the core essence and contribution of occupational therapy, students developed clarity of understanding about the uniqueness of the profession. This is important in light of the historical difficulty occupational therapists have had in articulating their unique role and professional identity.
Home Safety for Children with Autistic Spectrum Disorder: Local Authority Occupational Therapy Intervention
Authors: Boyle Paul , Haines David , Lovelock Linda , Innes Kati 
Published: May 2014

Introduction: Health and social care agencies are encouraged to provide child-centred services that respond to needs that change over time. There is evidence that occupational therapists are concerned about how to respond to issues of harmful behaviour in the home environment whilst promoting child development. This study explored occupational therapists' experiences regarding harmful behaviour and the safety of children with Autistic Spectrum Disorder. Method: Seven community occupational therapists, employed by a local authority and working in social care, participated in two focus groups. Findings: An inductive thematic analysis identified five broad themes. These were: ‘assessment is complex’, ‘child development and the home environment’, ‘importance of family-centred services’, ‘the need for additional services’, and ‘management of the disabled facilities grant’. Conclusion: Local authority occupational therapists prioritize supporting families to keep children safe. It is necessary to adapt the home to reduce hazards and for alternative interventions to be made available to address behavioural and sensory needs. Services such as sensory integration are lacking, and where they are available access is difficult. It is common for disabled facilities grants to fund adaptations; however, management of grants could be improved to meet the needs of these children and their families.
Evaluating the Impact of Audits and Feedback as Methods for Implementation of Evidence in Stroke Rehabilitation
Authors: Kristensen Hanne , Hounsgaard Lise 
Published: May 2014

Introduction: This paper evaluates audits and feedback as methods to increase implementation of evidence in stroke rehabilitation. Method: The study used an action research approach and theories of knowledge translation. A sample of 22 occupational therapists participated from two Danish hospitals that admitted stroke patients. Data collection methods included audits of occupational therapy medical records, documentations of daily practice, and collaborative discussions. Active feedback and discussions of the findings took place, at a group level in four local clinical audits. Data analysis of daily self-reported recordings and audits was descriptive. Audit data were analysed using descriptive statistics. A phenomenological hermeneutical interpretive methodology was used for analysing qualitative data. Findings: Audits and feedback were based on clear standards and contextual developing action plans. Daily practice in both settings adapted to the clinical guidelines. Implementations of the standardized assessment tools seemed to be the most successful. Conclusion: The effects of audit and feedback profited from the active participation of the therapists, as well as local gatekeepers having formal responsibilities for implementing change. The process was strengthened by providing the audits and feedback more than once. The effect of audits and feedback was positively influenced by being in line with current conceptual frameworks, local policies, and values.

ABSTRACT

Objective
The aim of this study was to assess the incidence of micronuclei (MN) in buccal mucosal cells of professionals working in radiology area to determine the risk of stochastic effects of radiation.

Materials and methods
All the professionals and students working in King Khalid University - College of Dentistry radiology area were included in the Risk Group (RG = 27). The Control Group (CG = 27) comprised of healthy individual matching the gender and age of the RG. Buccal mucosal scraping from all the 54 subjects of RG and CG were stained with Papanicolaou stain and observed under oil immersion lens (×100) for the presence of micronuclei (MN) in the exfoliated epithelial cells.

Results
There was no significant difference between the incidence of MN in RG and CG (p = >0.05) using t-test.

Conclusion
Routine radiation protection protocol does minimize the risk of radiation induced cytotoxicity, however, screening of professionals should be carried out at regular intervals.

Authors: Borges Alvaro Henrique , Bandéca Matheus Coelho , Leite Fabio Renato Manzolli , Leite Amauri Antiquera , Sampaio José Eduardo Cezar , Pinto Shelon Cristina Souza , Fontanari Lucas Amaral , Cavassim Rodrigo 
Published: May 2014

ABSTRACT
This study analyzes the clot stabilization on root surfaces of teeth impregnated with cotinine and nicotine and the influence of the scaling in the adhesion of blood components, observing the influence of new exposition to nicotine and/or cotinine after scaling. Fifteen human teeth extracted due to periodontal disease of non-smokers patients were selected and manually scaled. Four dentin blocks were obtained from each tooth (n = 60). Samples received blood application or reimpregnation with nicotine and/or cotinine, depending on the groups. Group 1: PBS immersion + root scaling + blood; group 2: nicotine + root scaling + blood; group 3: nicotine + root scaling + nicotine reapplication + blood; group 4: cotinine + root scaling + blood; group 5: cotinine + root scaling + cotinine reapplication+ blood; group 6: nicotine and cotinine + root scaling + nicotine and cotinine + blood. Samples were kept in 2 ml of each substance for 24 hours. Each group received a blood drop and was analyzed by SEM. The higher amount of blood components was present in teeth exposed to cotinine and the groups submitted to scaling and blood application in comparison with groups that received reapplication of toxic substances after scaling. The greater toxic effect on root dentin surface was after the exposure to nicotine and cotinine. Results suggest that periodontal healing may be delayed in smokers due to the direct inhibition of clot stabilization on the root surface when nicotine and cotinine are present concomitantly.

Authors: Can Gülsen , Özmumcu Baransel , Altinci Pinar 
Published: May 2014

ABSTRACT

Aim
To investigate the importance of attachment types on the retention loss of extracoronal attachment-retained removable partial dentures depending on the usage period.

Materials and methods
In order to observe the retention loss of 5 different attachments (OT Strategy, OT Strategy-metal protected, Vario-stud-snap and Vario-soft 3 and ERA-RV) over time, attachment-retained partial dentures representing Kennedy II mod. I case were placed in a custom-made, retention test machine. For each minute, eight separating and joining movements were performed and retention values (Newton) of the attachments were recorded by computer. The retention tests implemented in 540,1080 and 2160 cycles. The data were evaluated statistically according to the two-way ANOVA and Tukey parametrical tests.

Results
The slide type attachment providing the best retention force was observed to be the most worn out by this process (p < 0.01) while the ball type attachments, which typically have the lesser retention force, showed less retention loss (p < 0.01).

Conclusion
It can be concluded that the retention attributes of the attachment-retained dentures were affected by the specific type of precision attachment as well as the usage period.

Clinical significance
Precision attachments with ball-type plastic matrices may be recommended for the clinical use due to their retention stability over time.

Authors: Belludi Sphoorthi Anup , Verma Shiras , Banthia Ruchi , Bhusari Prashanth , Parwani Simran , Kedia Sameer , Saiprasad SV 
Published: May 2014

ABSTRACT

Purpose
Several epidemiologic studies have suggested a role of tomato products in decreasing the risk of the development of diseases related to oxidative stress (cancer and other chronic diseases). Oxidative stress may result in periodontal tissue damage either directly or indirectly. Lycopene, a powerful antioxidant and the main carotenoid in tomato products possesses the greatest quenching ability of singlet oxygen among the various carotenoids and is effective in protecting blood lymphocytes from NOO-radical damage. Hence, the aim of the present study is to compare the effect of systemically administered lycopene as an adjunct to scaling and root planing in patients with gingivitis and periodontitis.

Materials and methods
Twenty systemically healthy patients were involved in a randomized, double-blind, parallel study and based on their clinical signs were divided into two groups of mild to moderate periodontitis (A) and moderate gingivitis (B). The subjects under the groups A and B were randomly distributed between the two treatment groups: test group (n = 5), 4 mg lycopene/day for 2 weeks with oral prophylaxis (full mouth scaling and root planing (SRP) completed within 24 hours) and controls (n = 5), receiving only oral prophylaxis. Pre- and post-therapeutic periodontal parameters were evaluated.

Results
In group A, statistically significant improvement in CAL was reported in test group as compared to control group. In group B, the difference between pretreatment and post-treatment bleeding on probing scores was found to be statistically non-significant in both groups.

Conclusion
Results show that lycopene is a promising treatment modality as an adjunct to full mouth SRP of the oral cavity in patients with moderate periodontal disease.

Clinical significance
Modulation of the free radical production seems to be essential for the inhibition of tissue destruction, and treatment with antioxidants, like lycopene, which is the most potent among them will block the production of free ROS or its effects might prove to be therapeutically valuable.

Published: May 2014

ABSTRACT

Background
Local delivery of antimicrobial agents provides higher concentration of the drug in the periodontal site for longer periods than systemically delivered methods. In the present study an attempt is made to know the efficacy of controlled local drug delivery of doxycycline as an adjunctive treatment in the management of chronic periodontitis.

Materials and methods
A total of 12 patients, diagnosed as Chronic Periodontitis in the age of 25 to 55 years, were selected of both the sexes in this study. They were divided into Experimental group consisted of 30 sites who received complete scaling and root planing (SRP) followed by placement of Atridox gel and control group consisted of 30 sites who received only SRP. Clinical parameters were recorded at, baseline, days 30, 90 and 180. Parameters were plaque index, gingival index, gingival bleeding index and microbial analysis, probing pocket depth and Clinical attachment level (CAL). The microbiological analysis was done at baseline visit and at 90th day. Probing pocket depth and CAL were recorded only on day 0 and 180th day.

Results
In 180 days study, both the groups exhibited a significant improvement in periodontal status. Significant gain in attachment level was observed in both the group. Between both the groups the clinical parameters in the experimental groups exhibited better results as compared to the control group. Both the groups exhibited significant reduction in the number of spirochetes.

Conclusion
Combination therapy of SRP and 10% DH gel demonstrated better results at all levels suggesting that this therapy can play a significant role as an adjunct to SRP in the management of chronic periodontitis.

Effects of Bimax and Segmental Surgeries for Correction of Bimaxillary Dentoalveolar Protrusion Class I on Soft Tissue Parameters: Upper lip Thickness and Curvature, Nasolabial Angle and Nasal Prominence
Authors: Rahpeyma Amin , Khajehahmadi Saeedeh 
Published: May 2014

ABSTRACT

Aim
Results of this study can show if bimax surgery for posterior repositioning of maxilla and correction of BPCLI has priority to the currently used segmental orthognathic surgery or not.

Materials and methods
This study was done on 40 whiteskinned Iranian patients with bimaxillary dentoalveolar protrusion class I (BPCLI) who sought treatment for their deformity. In the first group, treatment includes segmental surgery for backward replacement of anterior segment of the upper and lower jaw. In the second group, treatment was bimax surgery, in which whole upper and lower jaw moved backward. Twenty patients were included in each group. For this purpose, we measured upper lip thickness (ULT, distance between LS and IA), nose prominence (NP, distance between nasal tip and the perpendicular line from upper lip vermilion on FHP), subsulcus depth (SSD, distance of SLS from this perpendicular line), SN to H line distance and finally, nasolabial angle (NLA) before and after surgery.

Results
In our study, 65% of patients were female and the mean of age was 27 (17-39) years old. The mean of SNA, SNB, ANB and INA in our patients were 81.7 ± 2.9, 78.8 ± 2.8, 4.50 ± 1.4 and 120 ± 8.7, respectively. All variables except SSD were analyzed with t-test to compare the results of two methods of surgery. Differences in the values of NP, NLA, SN to H line distance and ULT before and after segmental and bimax surgeries between before and after surgery were significant. After surgeries, ULT and the SN to H line distance reduced significantly, and NLA became corrected to its normal range (90-110).

Conclusion
The results of this study showed that bimax and segmental surgeries can effectively correct BPCLI. Because of possible dental and periodontal complications of segmental surgery, we highly recommend bimax surgery for treatment of BPCLI.

ABSTRACT

Aim
This study investigated the flowability, setting time, pH, calcium release and bond strength of a MTA-based cement (MTA Fillapex®) compared to AH Plus and Sealapex.

Materials and methods
For the flowability test, the ISO 6876:2001 specification was utilized and for the setting time test, the ASTM C266-03 specification was utilized. For the pH and calcium release measurements, 10 samples were prepared for each group and analyzed for several different periods. For the push-out test, dentin disks were distributed into three groups, according to the cement utilized and into three subgroups, according to the root third (n = 10). After obturation, the specimens underwent push-out testing. The data were compared statistically using a significance level of 5%.

Results
The flowability of all materials was found to be similar (p > 0.05). The setting times were different among the groups tested (MTA Fillapex < Sealapex < AH Plus) (p < 0.05). At days 7 and 28, the MTA Fillapex presented the higher pH values (p < 0.05). At 24 hours and at 14 days, the calcium release of the MTA Fillapex was similar to that of Sealapex (p > 0.05). AH Plus presented the lowest pH and calcium release values (p < 0.05). In all root thirds, the adhesion to the dentin of the MTA Fillapex and Sealapex were significantly lower than that of AH Plus (p < 0.05).

Conclusion
MTA Fillapex and Sealapex presented several similar properties and both were found to be different than AH Plus.

Clinical significance
This study evaluated the physicochemical and mechanical properties of new MTA-based root canal cement, in order to use this scaler in root canal fillings. MTA Fillapex showed satisfactory properties for clinical use.

ABSTRACTThe denture bases made by using polymethyl methacrylates of Acrylic resin family have excellent physical properties, simple to process and easy to reline, rebase and repair. One of the inherent disadvantages of this material is the liability to break during function. The strength assessment of acrylic resins have been made generally by transverse deflection tests.AimTo evaluate the impact strength valves of certain brands of commercially available denture base resins and suggest their suitability.Materials and methodsThe denture bases we made using polymethyl methacrylates of acrylic resin family because they have excellent physical properties, simple to process and easy to reline and rebase. Six commercial brands of polymethyl methacrylate, namely Stellon (DPI-India), Acralyn-H (Asian Acrylate, India), Trevalon (Dentsply-England), Lucitone 199 (Dentsply/ York division), Acralyn-H (Super Unbreakable), Trevalon HI (Dentsply, Detray division, England) were tested by breaking them using Analog Pendulum (ASTM D 256).ResultsFrom the entire study the maximum impact strength was reported for Acralyn-H super unbreakable (Asian Acrylates, India) 62.19 joules.ConclusionAll the analysis led to conclusion that there is basic change in material composition within and among the different groups of denture base resins.Clinical implicationsThe complete dentures made using denture base resins with high impact strength valves (e.g. Acralyn-H super unbreakable) will be more durable and can be used by the patient for considerable period of time, i.e. beyond 4 to 5 years.How to cite this articleNarendra R, Reddy NS, Reddy SD, Purna CRS, Shekar MC, Balasubramanyam S.
