Incorporating critical appraisal into your academic writing or when debating use of evidence in practice In this chapter so far, we have considered ways of making sense of research and non-research evidence you may encounter. Overall, the purpose of criti- cal appraisal is to enable you to make sense of the evidence you come across. It takes you from a position of ‘do not believe everything you read’ to the position in which you have the skills to assess and evaluate what you read so that you can determine the strengths and weaknesses of the evidence you encounter. It is important to remember that you need to critically appraise – make sense of – all the evidence you read, whether you are using that evidence in your 140 How do I know If tHe evIdence Is convIncIng and useful? However, when you are using evidence in your academic work, it is useful to be mindful of the following points. As can be seen in the example above, it is important to distinguish between a research study based on evidence, and if so what type of evidence, or merely an opinion. This is relevant whether you are debating the use of evidence in practice or in academic writing. As a general rule, avoid writing a statement and only giving the author’s name (such as ‘Jones (2006) says’) as the reader is completely unaware of the context of Jones work. In summary Once you have found your evidence, it is vital that you are able to look at it objectively and work out frstly what it is, and secondly, whether it helps you to address what you need to fnd out. The purpose of critical appraisal is to determine the relevance, strengths and limitations of the information key poInts 141 collected so that you can determine how helpful the evidence is in answer- ing your question. A study might be well carried out but not very relevant to your research question. Alternatively, a study might be very relevant to your research question but not well designed or implemented. Furthermore, discus- sion and expert opinion might add interesting insight to your argument, but the quality of this information also needs to be assessed. In a society with well-informed or ‘expert patients’ and free and easy access to informa- tion we are more likely to be challenged and called to account for our practice decisions. Throughout this book, we have outlined the steps you need to take when you defne an area for exploration, and start to search for and evaluate the evidence you fnd. Even searching for and evaluating the evidence is fairly straightforward once you have worked out how to do it. We should perhaps be more aware of this and address the implementation and uptake of evidence. They emphasize: Simply making research available does not ensure that those who need to know about it get to know about it, or can make sense of the fndings. Once we know about the evidence, we need to use it and evaluate its use in practice. Over recent years there has been a large body of literature that has explored the problems of implementing an evidence-based approach. Identify how this relates to the issues you have identifed, read the rest of this chapter and then set a goal to adopt some of the ideas that may help you to overcome some of these barriers. Looked at broadly, these barriers relate to both individual and organizational factors. In the next section, we will consider what we can do at an individual and an organizational level to reduce these barriers to the implementation of an evidence-based approach in professional practice. The individual prac- titioner needs to have certain motivations, knowledge and skills in order to adopt evidence-based practices.

Maxillary primary to primary canines and just mesial to primary second second molars may even have a cusp of Carabelli molars. The crown of the maxillary second premolar develops in the space bounded by these roots. From this aspect, the primary maxillary second molar resembles a miniature 6-year first molar (even with a Carabelli cusp). Since these teeth are adjacent to one another during an important clue for tooth identification.

In the maxillary arch, the fifth tooth from the midline on the left side of the photograph is a second premolar. On the right side, a retained primary canine is still present and the permanent canine has erupted quite labial to the arch, but if you consider that the third position from the midline is reserved for the permanent canine, then the fifth tooth on the right side is a primary second molar. Notice the similarity of the primary second molar with the larger 6-year molar just distal to it. Also notice the position of the secondary maxillary canine, which is normally the last succedaneous tooth to erupt (positioned just labial to the primary canine, which is still present). In the mandibular arch, the fifth tooth from the midline on both the right and left sides is a primary second molar. Notice the similarity in morphology with the larger 6-year molar just distal to it (sixth from the mid- line). Unique traits of Primary Mandibular permanent molar crown is that primary molars have Second Molars a much more prominent mesiobuccal cervical ridge As on permanent mandibular first molars, primary and constricted crown cervix compared to permanent mandibular second molars have five cusps: three buc- molars.

Muscular Strength Although muscular strength refers to the external force (properly expressed in newtons, although kilograms and pounds are commonly used as well) that can be generated by a specific muscle or muscle group, it is commonly expressed in terms of resistance met or overcome. Static or isometric strength can be measured conveniently using a variety of devices including cable tensiometers and handgrip dynamometers. Measures of static strength are specific to the muscle group and joint angle involved in testing and thus may be limited in describing overall muscular strength. Despite this limitation, simple measurements such as handgrip strength have predicted mortality and functional status in older individuals (99,109). Adjust the grip bar so the second joint of the fingers fits snugly under the handle and takes the weight of the instrument. The subject holds the handgrip dynamometer in line with the forearm at the level of the thigh, away from the body. The subject squeezes the handgrip dynamometer as hard as possible without holding the breath (to avoid the Valsalva maneuver). Neither the hand nor the handgrip dynamometer should touch the body or any other object. The score is the highest of the two readings (to the nearest kilogram) for each hand added together. Norms based on resistance lifted divided by body mass for the bench press and leg press are provided in Tables 4. Free weights and other brands of resistance exercise machines which are more commonly used today may not provide the same weight–press ratio and to date have not been validated (54). Select an initial weight that is within the subject’s perceived capacity (~50%–70% of capacity). Such devices measure peak rotational force or torque, but an important drawback is that this equipment is substantially more expensive compared to other strength testing modalities (39). If the total number of repetitions at a given amount of resistance is measured, the result is termed absolute muscular endurance. A simple field test such as the maximum number of push-ups that can be performed without rest may be used to evaluate the endurance of upper body muscles (18). Previous editions of this publication included the curl-up (crunch) test as a simple field test for the measurement of muscular endurance. This edition of the Guidelines does not include the curl-up test in light of recent research suggesting that the test may not be sensitive enough to grade performance and may cause lower back injury (77,78,107). The push-up test is administered with men starting in the standard “down” position (hands pointing forward and under the shoulder, back straight, head up, using the toes as the pivotal point) and women in the modified “knee push-up” position (legs together, lower leg in contact with mat with ankles plantar-flexed, back straight, hands shoulder width apart, head up, using the knees as the pivotal point). The client/patient must raise the body by straightening the elbows and return to the “down” position, until the chin touches the mat. For both men and women, the subject’s back must be straight at all times, and the subject must push up to a straight arm position. The maximal number of push-ups performed consecutively without rest is counted as the score. The test is stopped when the client strains forcibly or unable to maintain the appropriate technique within two repetitions. Flexibility depends on a number of specific variables including distensibility of the joint capsule, adequate warm-up, and muscle viscosity. Just as muscular strength and endurance is specific to the muscles involved, flexibility is joint specific; therefore, no single flexibility test can be used to evaluate total body flexibility. Common devices for this purpose include goniometers, electrogoniometers, the Leighton flexometer, inclinometers, and tape measures.
