Watermemories: A Swimming Club for Adults with Dementia
Authors: Neville Christine , Clifton Karen , Henwood Tim , Beattie Elizabeth , McKenzie Mary-Ann
Published: January 2013

The purpose of this article is to describe the conceptual model and implementation strategies of an evidence-based, aquatic exercise program specifically targeting individuals with dementia—The Watermemories Swimming Club (WSC). Physical exercise not only improves the functional capacity of people with dementia but also has significant effects on other aspects of quality of life such as sleep, appetite, behavioral and psychological symptoms, depression, and falls. Additionally, exercise can improve a person’s overall sense of well-being and positively enhance their sociability. The WSC was designed to increase physical exercise while being easy to implement, safe, and pleasurable. Many challenges were faced along the way, and we discuss how these were overcome. Implications for nurses are also provided.
Exploring Attitudes and Barriers Toward the Use of Evidence-Based Nursing among Nurse Managers in Taiwanese Residential Aged Care Facilities
Authors: Chang Hui Chen , Jones Mairwen K. , Russell Cherry
Published: January 2013

This article reports findings from a qualitative study on nurse managers’ perspectives of evidence-based practice (EBP) in residential aged care facilities (RACFs) in Taiwan. Six RACFs were randomly selected for inclusion in the study. The sample consisted of the nurse manager from each facility (
N
= 6) who participated in an in-depth interview. Thematic qualitative content analysis was used to identify patterns of experience. The majority of managers expressed positive attitudes toward research and EBP but reported little experience in its implementation. Barriers to EBP included individual barriers such as lack of motivation and confidence to embrace change. Research-related barriers included difficulty in finding and understanding research articles, and systemic barriers included lack of funding and time, lack of authority, and workplace culture. Some implications of these findings for policy and practice are discussed.
Bringing the Institute of Medicine’s Report to Life: Developing a Doctor of Nursing Practice Orthopedic Residency
Authors: Instone Susan L. , Palmer Debra M.
Published: January 2013

The increasing number of Americans needing orthopedic health care is a growing concern given the aging population and the diminishing pool of primary and specialty care physicians. In a call to action, the Institute of Medicine’s report,
The Future of Nursing
, advocates for innovative solutions, including the transformation of nursing education and practice, to meet the health care needs of our nation. Preparing nurse practitioners to fill this gap through the development of an orthopedic residency option within the Doctor of Nursing Practice (DNP) degree can fulfill this need. The logic model can serve as a guide to develop and evaluate such a program. The alignment between the American Association of Colleges of Nursing’s DNP
Essentials
and the resources, curriculum, outcomes, and impact of an orthopedic residency is described so similar programs can be established to improve the access to orthopedic care by doctorally prepared nurse practitioners.
Learning Through Collaboration: The NEXus Consortium as a Winning Collaborative
Authors: Komnenich Pauline , Hayes Janice S. , Magilvy Kathy , McNeil Paula A.
Published: January 2013

The Nursing Education Exchange (NEXus) is a consortium of academic doctoral programs in nursing, initiated in response to a national shortage of well-qualified nurse educators and the need to increase the number of doctoral faculty in nursing programs across the United States. The vision for the consortium was to use distance-accessible delivery methods to provide rural nurse educators and clinical nurses with access to quality doctoral programs in nursing while remaining in their home environments. In addition, smaller or newly established doctoral programs would be able to offer a wider variety of elective coursework without recruiting and hiring additional faculty, further decreasing their limited available resources. This article describes the initiation and implementation of a successful nursing education collaborative that has gained increasing influence across the country and is recognized by its acronym, NEXus.
Ketamine for the Treatment of Depression
Authors: Howland Robert H.
Published: January 2013

Ketamine (Ketalar®) is an anesthetic agent derived from the hallucinogenic drug phencyclidine (PCP). It is a high-affinity antagonist at N-methyl-D-aspartate receptors and also binds to opioid mu and sigma receptors. Ketamine is being intensively investigated as an antidepressant therapy. To date, five short-term controlled studies and other open-label studies in patients with unipolar or bipolar depression have demonstrated that intravenous ketamine is safe and has a rapid and profound short-term effect on depressive symptoms, including suicidal thoughts, even among patients considered treatment-resistant to standard medications or electroconvulsive therapy. Before ketamine can be incorporated into clinical practice, however, its long-term safety and effectiveness need to be evaluated. Although the effectiveness of alternative routes of ketamine administration (i.e., oral, intranasal, or intramuscular) needs to be determined, intravenous ketamine could be conceptualized as a clinic-based procedural therapy for treatment-resistant forms of depression.
Military Sexual Trauma: A Silent Syndrome
Authors: Burgess Ann W. , Slattery Donna M. , Herlihy Patricia A.
Published: January 2013

This article examines an age-old problem—sexual assault—through the lens of its occurrence within the military culture. Specific cases as well as U.S. Department of Defense responses to better handle these issues are offered to educate psychiatric-mental health nurses of the potential differences in symptomatology and presentation of military sexual trauma (MST). This appears to be an increasing problem with the predicted cohort of returning veterans appearing both in the U.S. Department of Veterans Affairs system as well as in civilian locations, hospitals, community centers, and especially the workplace. It will be critical to develop training materials and pursue further research to identify this silent syndrome of MST to better meet the needs of our returning veterans.
Reflective Assignments in Mental Health Nursing Courses: Factors to Consider
Authors: Cleary Michelle , Horsfall Jan , Hunt Glenn E.
Published: January 2013

It is important that mental health educators are clear about the nature and practice of reflective processes and their appropriate uses and inherent challenges. Active reflection was developed as a strategy for professional self-improvement in practice-based disciplines. Some mental health nursing courses use reflective exercises as a formal student assessment component. In this article, the authors draw on their experience and the literature to identify issues relating to aspects of the course, educators, and students that are associated with incorporating reflection-related activities as compulsory assessable items in an undergraduate nursing course.
Depression Treatment in Assisted Living Settings: Is an Innovative Approach Feasible?
Authors: Smith Marianne , Haedtke Christine
Published: January 2013

Depression is a common, disabling, and underrecognized problem among older adults in assisted living (AL) settings. The purpose of this study was to evaluate stakeholder perceptions of using a blended model of depression care that combines essential features of evidence-based collaborative care and older adult outreach for use in AL settings. A descriptive mixed-methods design was used to assess perceptions of the three main components of the depression model: onsite depression care management, staff development activities, and AL nurses as staff resources and liaisons to primary care providers. Quantitative and narrative responses were consistently positive and supportive of depression care approaches. Potential barriers included time constraints for staff and costs for residents. These data provide strong support for further evaluation of the blended depression model. Staff development activities may be implemented independent of the model to enhance depression recognition, assessment, and daily care approaches in AL.

Speleogenesis along deep regional faults by ascending waters: case studies from Slovakia and Czech Republic
Authors: Bella Pavel , Bosak Pavel
Published: January 2013

The most conspicuous six examples illustrating ascending (perascensum) speleogenesis linked with deep faults/fault systemswere selected from Slovakia and Czech Republic. In the past,the caves have been described as product of phreatic, epiphreaticand vadose speleogenesis related to the evolution of localwater courses and valley incision, and linked mostly with Pleistocenegeomorphic evolution. Our analysis illustrates severalcommon characteristics of caves: (1) they developed along or inclose vicinity of deep faults/fault zones, commonly of regionalimportance; (2) the groundwater ascended due to deep faults/fault systems mostly as results of deep regional circulation ofmeteoric waters from adjacent karst or nonkarst areas; (3) the3D mazes and labyrinths dominate in cave morphology; (4)speleogens (e.g., cupolas, slots, ceiling channels, spongework,rugged phreatic morphology especially along slots) indicateascending speleogenesis in deep phreatic to phreatic environments;(5) they exhibit poor relation to the present landscape;in some of them fluvial sediments are completely missing inspite of surface rivers/streams in the direct vicinity; (6) strongepiphreatic re-modelling is common in general (e.g., subhorizontalpassages arranged in cave levels, water-table flat ceilingsand notches) and related to the evolution of the recent landscape;(7) recharge structures and correlate surface precipitatesare poorly preserved or completely missing (denuded) on thepresent surface in spite of fact that recent recharges broadlyprecipitate travertines; (8) caves can be, and some of them are,substantially older than the recent landscape (Pliocene, Miocene),and (9) caves were formed in conditions of slow water ascent, which differentiate the process from faster vauclusianascending speleogenetical models. Any of described caves containsclear diagnostic features of real hypogene caves. There aremissing evidences that at least heated groundwaters took partduring speleogenesis of studied caves, nevertheless, somewhatincreased water temperature can be expected during speleogenesisat least in some of caves. Any of described caves cannotbe directly characterized as product of thermal waters or hydrothermalprocess (i.e. as real hyperkarst sensu Cigna 1978),therefore they do not represent hypogenic caves.
New data on the development of the Baradla Cave (Hungary, Aggtelek karst)
Authors: Márton Veress
Published: January 2013

The development of karst landforms of the Aggtelek Plateau was investigated concerning the role of these valleys in the genesis of the Baradla Cave, which is located on the Plateau. New data were collected by geophysical method (Vertical Electrical Sounding) from a few dolines of a selected valley of the Aggtelek Plateau. The geophysical profiles confirm that the dolines of the valley bottom did not develop from sinkholes, but they are solution dolines. Morphological characteristics of the valleys of the Plateau suggest that these valleys are not the continuation of the valley of the recent covered karst. The former catchment area of these valleys might have been on the Plateau and north of Kecső valley. Their bottoms tilted into southern direction. Therefore the subsurface capture places of their streams might have been near to the recent sinking line.The sediments (Borsodi Gravel Formation) which were eroded from the above mentioned areas also contributed to the genesis of the Baradla Cave.
Water supply spring zone Novljanska Žrnovnica (Croatia) – new quantities of drinking water in the conditions of salt water intrusion
Authors: Biondić Ranko , Biondić Božidar , Meaški Hrvoje
Published: January 2013

This paper presents an approach for solving the problem of exploitation of freshwater in the coastal karst aquifer during summer dry periods in the conditions of potential salt water intrusion. The approach is presented on the example of spring zone Novljanska Žrnovnica, situated in the northern part of Croatian Adriatic coastal region. The spring zone is used for water supply (about 250 l/s) of an important tourist area of Crikvenica and Novi Vinodolski. After unsuccessful attempts of physical separation of freshwater system from the sea influence, by construction of grout curtain, hydrogeological studies have focused on the possibility of groundwater capturing in the hinterland of discharge zone, outside of the zone of periodical salinity. The final research results with the exploitation well in the spring hinterland can serve as a model for research and exploitation of drinking water in natural conditions of unstable freshwater-saltwater interface in similar natural conditions.
Fifty Years of the Hypotelminorheic: What Have We Learned?
Authors: Pipan Tanja , Fišer Cene , Novak Tone , Culver David C.
Published: January 2013

Originally described by Meštrov in 1962, hypotelminorheic habitats are superficial subterranean drainages, typically less than a meter or so in depth, that emerge at small seepage springs. These are persistent wet spots, typically with blackened leaves in small depressions. There may be no flow during dry periods, but the underlying clay retains water above. They share the landscape with other small bodies of water (močila in Slovenian), not necessarily connected with groundwater. Hypotelminorheic habitats (mezišča in Slovenian) usually harbor a fauna dominated by species adapted to subterranean life, characteristically without eyes or pigment. The basic chemistry and hydrology of the habitat is described as are the basic faunal elements. The habitat is placed in a more general context by reviewing how species invade the habitat, their morphology, and their possible connection to deeper subterranean habitats.

The Effect of Immigration on Unskilled Native Workers: Evidence from a Natural Experiment
Authors: Asali Muhammad
Published: January 2013

This study exploits the natural experiment, provided by the start of the second intifada, to measure the effect of immigration on the wage and employment of unskilled native workers. It finds that immigration has no effect on the wage or employment of unskilled Jewish workers. The wage and employment of the least‐skilled Israeli Arab workers (with zero to five years of schooling) are adversely affected by immigration. The slightly more skilled Arab workers (with six to 11 years of schooling), in contrast, are positively affected by immigration, suggesting a complementarity effect with this group. Different explanations are proposed.

Correlation between Health and Nutritional Status in Geriatric Population
Authors: Kumar Dheeraj , Rastogi Namrata , Madan Ravi
Published: January 2013

Introduction

Impaired oral health interferes with the masticatory ability of an individual causing dietary restrictions, resulting in decreased intake for key nutrients, i.e. iron, fiber, vitamin C, etc. Therefore, the main aim of this survey was to assess whether the oral condition of geriatric population is directly or indirectly related to the intake of selected nutrients.

Aim

It is presumed that the number of teeth affect the type of food consumed by an individual. This choice of food may compromise the nutritional value of the diet. The aim of this study is to find a correlation between the nutritional statuses of an individual to the number of teeth present.

Materials and methods

The subjects from the local population available were equally divided on the basis of number of posterior occluding pairs (POP) present and the detailed information about the quantity and quality of food consumed was collected and then this available data was converted to nutritional intake value and then statistical analysis was undertaken.

Results

It is seen that body mass index (BMI) has no correlation with the dental status of an individual, but nutrient intake is directly related to the number of POPs of natural teeth.

Conclusion

In the present study, it was observed that edentulous participants consumed less dietary and crude fibers and consumed more saturated fat and cholesterol than participants with 21 or more teeth. Therefore, one must actively improve the oral care throughout his life to further increase the overall quality of life.

Injection Molding Technique for Fabrication of Flexible Prosthesis from Flexible Thermoplastic Denture base Materials
Authors: Singh Kunwarjeet
Published: January 2013

Purpose

To know properties, step-by-step procedure for fabrication and insertion of flexible prosthesis.

Background

Flexible denture base materials were introduced to dentistry by the name of Valplast and Flexiplast in 1950's. Injection molding technique is used for fabrication of various types of prostheses from these materials and fluid resins. Pryor used injection molding technique for introducing unpolymerized acrylic resin into the mold. In the mid 1970's Ivoclar introduced an injection molding system which used an acrylic resin modified for the injection molding process. Recently, numbers of dental manufacturing companies have introduced injection molding systems.

Materials and methods

The flexible denture base materials are superpolyamides which are available in the form of granules in cylinders of different sizes. These materials are thermoplastic in nature and needed to be converted into fluid form before pouring into mold under pressure. Each cylinder should be plasticized for 15 to 20 minutes at 550 to 560°F in an electric cartridge furnace before injecting the material into the flask. While injecting, the cylinder should be aligned with opening of flask and the levers of the press should be turned rapidly to apply firm pressure until the springs of the press are fully compressed. The pressure should be maintained for 3 to 5 minutes and the flask should be allowed to bench cool for 15 to 20 minutes before opening.

Conclusion

This technique can be used for fabrication of different types of prostheses from flexible denture base materials and fluid resins.

Effect of Acidic Environment on the Push-out Bond Strength of Biodentine™
Authors: Poplai Gaurav , Jadhav Sameer
Published: January 2013

Introduction

An apical sealing material may be exposed to an inflamed environment with low pH levels. The change in physical and chemical properties of mineral trioxide aggregate has been well-documented in the presence of low pH. However, on literature search there is no documentation of the effect of low pH on Biodentine™.

Aim

To compare the effects of various levels of acidic pH on the push-out bond strength of Biodentine™.

Materials and methods

Forty root dentin slices from single rooted human teeth were sectioned horizontally. The canal lumens were instrumented to obtain a standardized diameter of 1.3 mm and filled with Biodentine™. The specimens were then randomly divided into four groups (n = 10) and wrapped in pieces of gauze soaked in phosphate buffer saline solution (pH = 7.4) and butyric acid buffered at pH values of 4.4, 5.4 and 6.4 respectively. They were incubated at 37°C for 4 days. Push-out test were then carried out using universal testing machine. The data was analyzed using one-way analysis of variance (ANOVA) technique with Tukey's correction for multiple group comparisons.

Results

Data was subjected to one-way ANOVA using Tukey's post hoc test. Group I (control, pH = 7.4) showed greatest bond strength of 19.5 ± 0.9 MPa. The least push-out bond strength of 11.7 ± 0.5 MPa was observed in Group IV where the specimens were soaked at pH 4.4. A p-value less than 0.05 were considered to be statistically significant.

Conclusion

The force needed to displace Biodentine was significantly lower in samples stored at lower pH values.

Application of Er:YAG and Er, Cr:YSGG Lasers in Cavity Preparation for Dental Tissues: A Literature Review
Authors: Bandéca Matheus Coelho , Santos CR , Tonetto MR , Presoto CD , Oliveira OB , Calabrez-Filho S , Andrade MF
Published: January 2013

The laser has been widely used in many specialties of dentistry and several wavelengths have been investigated as a substitute for high-speed handpiece. The purpose of this paper is to review the literature about the use of Er:YAG and Er, Cr:YSGG lasers in cavity preparation for dental tissues. Despite the differences in wavelength, pulse duration and energy, the morphological characteristics of the irradiated dentin surface with these lasers are comparable, as well as its effects as methods of dental caries prevention. Thus, Er:YAG and Er, Cr:YSGG lasers prepared cavities with similar effects on the dental tissue, however, further investigations about ideal irradiation conditions are needed for both lasers.

Clear Cell Tumors of the Head and Neck: An Overview
Authors: Premalatha BR , Neethi H
Published: January 2013

Clear cells are routinely encountered in the histopathological sections. They most frequently result from fixation artefacts; cytoplasmic accumulation of water, glycogen, lipids, mucins; hydropic degeneration of organelles, etc. When these clear cells predominate in a tumor, arriving at a definitive diagnosis becomes problematic. Thus, this review gives an idea of clear cells associated with various conditions, causes for clearing of these cells, clear cell tumors of the head and neck and a systematic approach towards arriving at an appropriate diagnosis of these tumors.

A Case Report of Mucormycosis of Faciotemporal Region Mimicking as Bacterial Necrotizing Fasciitis
Authors: Jeelani Waqar , Kamal Yousaf
Published: January 2013

Mucormycosis is an invasive and unyielding fungal disease of immunocompromised patients with a reported increase in incidence over last couple of decades. The close resemblance of clinical features of mucormycosis with that of bacterial necrotizing fasciitis can lead to misdiagnosis and thus delay in appropriate management. The case presented here involves a similar scenario when a middle-aged patient with multiple systemic problems reported to the tertiary care hospital 7 days after facial trauma from a road traffic accident. There was a purple black ulcerating lesion over left midface that was misdiagnosed and treated as a case of bacterial necrotizing fasciitis. Despite extensive debridement under general anesthesia and administration of parentral antibiotics, the patient failed to survive. The results of histopathological examination of the debrided tissue, that became available after the death of the patient showed, growth of broad aseptate hyphae characteristic of mucorales. Late presentation, multiple systemic diseases and missed diagnosis of the condition were the main factors that resulted in the death of the patient within 72 hours of presentation.

Underlying immunocompromised states and late diagnosis of this condition remain the key issues that need to be addressed in developing countries. A high degree of clinical suspicion and aggressive diagnostic measures combined with prompt medical and surgical treatment are essential to improve the outcome.

Effect of Methylxanthines (Coffee/tea Consumers) on Oral Precancer and Oral Cancer Patients with Smoking and Smokless Tobacco Habits
Authors: Ahmed Bijle Mohammed Nadeem , Zubairy Yasmeen F , Patil Vinayak W , Benjamin Tabita , Jangam Daya
Published: January 2013

Aim

To study, whether the consumption of regular tea/coffee (methylxanthines) increases the risk of oral cancer in patients with smoking and smokeless tobacco habits.

Materials and methods

This study was conducted on a total of 90 oral cancer and precancerous patients, from western Maharashtra (India) males in the age group of 20 to 45 years who were with smoking and smokeless tobacco habits; also regular tea/coffee consumers were subjected to biochemical parameters such as aspartate transaminase (AST) and alanine transaminase (ALT) from saliva and serum of patients with oral precancer (submucous fibrosis, leukoplakia) and oral cancer patients and compared with 90-age and sex-matched controls. Individuals consent was taken to measure their biochemical parameters, by using Hafkenscheid method in whole saliva and serum. Statistical analysis of variance (ANOVA) with Tukey's correction for multiple group comparisons was performed using Student t-test.

Results

Results show, that a statistically significant increase in value (p < 0.05) in ALT, AST in both saliva and serum was observed in precancerous and oral cancer patients among the study group as compared to the control group.

Conclusion

In the present study, there was increase in the levels of ALT, AST enzymes in both saliva and serum levels in the study group as compared to the control group which was statistically significant (p < 0.05) suggesting that long-term exposure of methylxanthines results in impairment of salivary gland antioxidant system which may affect the anticarcinogenic action of saliva.

Clinical significance

Oral fluids may be utilized effectively to study the variations in the biochemical constituents of saliva of leukoplakia, submucous fibrosis and oral cancer patients.

A Clinical Study to Evaluate and Compare the Masticatory Performance in Complete Denture Wearers with and without Soft Liners
Authors: Tata Sreeharsha
Published: January 2013

Aims and objectives

Soft liners are mainly used with complete dentures in case of poor mucosal conditions and for the even distribution of masticatory forces. However, there is some doubt as to whether the elasticity of the soft liner disturbs masticatory function because denture wearers may need extra force to compress the soft liners, leading to muscle fatigue. So, this clinical study was done to evaluate and compare the masticatory performance in patients wearing complete dentures with and without the use of soft liners.

Materials and methods

Twenty edentulous subjects were selected for the study. For each patient two sets of complete dentures were fabricated. First set without the use of soft liner and the second one for using with soft liner. Peanuts were selected as test food for the study and the chewed food was pooled for a single measurement and then poured on sieves. Both filter and filtrate were collected and was centrifuged. Masticatory performance in this study has been quantitated by dividing the volume of test food passing through the sieve by the total volume of test food recovered. The fraction is then expressed as a percent.

Results

With the paired t-test performed, significant difference was found between the masticatory performance in patients wearing complete dentures with and without the use of soft liners. 5% difference was seen in the mean performance.

Conclusion

It has been concluded from this study that, masticatory performance in patients wearing complete dentures with the use of soft liners was improved by 5% when compared to the patients wearing complete dentures without using soft liners.

Clinical significance

This present study indicates that the masticatory performance enhanced with the use of soft liners for complete denture patients.

Evaluation of Canine Retraction through Distraction of the Periodontal Ligament: A Clinical Study
Authors: Kumar KV Sujan , Umashankar K , Kumar D Pradeep , Kumar D Praveen
Published: January 2013

Aim

The aim of this study is to evaluate the efficiency of canine distraction and also to evaluate the position of canine in the arch after distraction.

Materials and methods

The study sample consisted of five patients, (4 males and 1 female), in the age group of 14 to 25 years who needed canine retraction (ten maxillary canines including both left and right) and first premolar extraction as their treatment protocol were included in the study. This study used a in-house manufactured periodontal ligament distractor.

Results

The maxillary canines were distracted distally by 6.42 mm in three and half weeks with a distal tipping of around 15.1° and the maxillary first molars tipped mesially by an average of 6.1°. The maxillary canines rotated mesiobucally by an average of 7.8° bilaterally. Conclusion: Canines can be distracted rapidly with minimal effects on the vitality and the periodontal condition and almost all of extraction space can be used for anterior dental alignment or retraction. Maxillary canines can be rapidly retracted into the first premolar extraction space at the rate of about 2.43 mm per week.

Conclusion

Canines can be distracted rapidly with minimal effects on the vitality and the periodontal condition and almost all of extraction space can be used for anterior dental alignment or retraction. Maxillary canines can be rapidly retracted into the first premolar extraction space at the rate of about 2.43 mm per week.

Clinical significance

The overall treatment time is reduced as the time taken for retraction of canine is decreased considerably from 6 and 8 months to 3 weeks. Also there is no significant anchorage loss during this period and is well suitable for cases with group a anchorage where the whole extraction space is needed for retraction of anterior teeth.

Over-bite and Vertical Changes following First Premolar Extraction in High Angle Cases
Authors: Girish KS , Ramesh GC , Pradeep MC , Kumar G Arun , Suresh BS
Published: January 2013

Aims and objectives

Orthodontists generally agree that nonextraction treatment is associated with downward and backward rotation of the mandible and an increase in the lower anterior face height (LAFH). They also agree that extraction line of treatment is associated with upward and forward rotation of the mandible and decrease in the LAFH. The intent of this cephalometric investigation was to examine the wedge hypothesis, that the vertical dimension collapses after first bicuspid extraction. The present study was undertaken to evaluate the cephalometric overbite and vertical changes following first premolar extraction in high angle cases.

Materials and methods

Forty-five adult patients having high mandibular plane angle, i.e. Gogn – SN more than or equal to 32° having class I molar and canine relation were included. Preand post-treatment lateral cephalograms were measured and compared to analyze the cephalometric changes.

Results

There was no decrease in the overbite and vertical changes following first premolar extraction in high angle cases.

Clinical significance

The facial complex does increase in size with growth, but mandibular plane while moving inferiorly, remain essentially parallel to its pretreatment position due to residual growth and treatment mechanics.

Conclusion

The study concluded that, There was no decrease in the vertical facial dimension, overbite and mandibular plane angle. However, it should be interpreted with caution, given the small sample size.

Aim

The aim of this study is to evaluate the dimensional accuracy of heat polymerized acrylic resin denture base clamped by the conventional method and by new-press technique and cured by long curing cycle.

Materials and methods

In this study, a total of 60 standardized maxillary record bases were fabricated with seven reference points as follows:

• Point A

Incisive papilla,

• Point B and C

Canine region on either side

• Point E and G

Midpoint of tuberosities on either side

• Point F

Midpoint of the line joining the two tuberosities

• Point D

Midpoint between the line joining A and F

Group A

Ten maxillary record bases were fabricated by conventional clamping method and cured by long curing cycle.

Group A’

Ten maxillary record bases were fabricated by New Press or RS tension clamping method and cured by long curing cycle.

Promising Role of Calcium Hypochlorite as a Disinfectant: An in vitro Evaluation Regarding its Effect on Type V Dental Stone
Authors: Swain Prasanta Kumar , Nagaral Sharanbasappa C , Kamalapurker Pawan Kumar , Damineni Ravishankar
Published: January 2013

Aim

The current study has been chosen to evaluate the efficacy of calcium hypochlorite as a disinfecting additive for the gypsum products and its effect on compressive and tensile strength of the set material. It is hypothesized that, the addition of calcium hypochlorite to type V dental stone in sufficient quantity to disinfect the material would have no deleterious effect on compressive or tensile strength.

Materials and methods

Total of 160 samples made up of type V dental stone were divided broadly into two groups of 80 samples each for the sake of compressive and tensile strength testing in dry and wet conditions: Out of each group, 10 samples without addition of any disinfectant (0% calcium hypochlorite) was compared with other group of 30 samples after adding disinfectant, i.e. each subgroup containing 10 samples each (0.5, 1.0 and 1.5% calcium hypochlorite).

Conclusion

Within limitations of thisin vitrostudy it is assumed to prepare type V dental stone that contains a disinfectant, has adequate compressive strength and tensile strength, and can significantly act against a resistant species likeBacillus subtilis.

Clinical significance

When calcium hypochlorite was added to dental stone, extra mixing water was required to produce a material of nearly same pouring consistency. The samples, which were put to microbiological tests, showed effective action of disinfectant onBacillus subtilis. No deleterious effect on compressive or tensile strength could be found after putting the selected samples with calcium hypochlorite.
