Correlation and regression 235 The final model with all variables and the interaction term included could be consid- ered to be over-fitted 250mg amoxil free shipping. By including variables that explain little additional variation and by including the interaction term 500 mg amoxil with visa, the model not only becomes complex but the preci- sion around the estimates is sacrificed and the regression assumptions of independence are violated purchase amoxil 250mg without a prescription. Head circumference should be omitted because of its relation with length and because it explains only a small additional amount of variation in weight. Once the final model is reached, the remaining regression assumptions should be confirmed. The residual distances are converted to standardized residuals that are in units of standard deviations from the regression. Standardized residuals are assumed to have a normal or approximately normal distribution with a mean of zero and a standard deviation of 1. Given the characteristics of a normal distribution, it is expected that 5% of stan- dardized residuals will be outside the area that lies between −1. In addition, 1% of standardized residuals are expected to lie outside the area between −3and+3 standard deviations from the mean. As the sample size increases, there will be an increasing number of potential outliers. In this sample size of 550 babies, it is expected that five children will have a standardized residual that will be outside the area that lies between −3and+3 standard deviations from the mean. The residual for each case can be saved to a data column using the Save option and the plots of the residuals can be obtained while running the model as shown in Box 7. The normality of the residuals can then be inspected using Analyze → Descriptive Statistics → Explore as discussed in Chapter 2. The Casewise Diagnostics table shows the cases that are more than three standard deviations from the regression line. There is only one case that has a standardized residual that is more than three standard deviations from the regression, that is, the baby with a weight of 5.

This is the minimum and maximum distances of babies from the equation, which is the variation about the regression. The standardized predicted values and standardized residuals shown in the Residuals Statistics table are expressed in units of their standard deviation and have a mean of zero and a standard deviation of approximately or equal to 1, as expected when they are normally distributed. The variance around the residuals can also be used to test whether the model vio- lates the assumption of homoscedasticity, that is, equal variance over the length of the regression model. Univariate outliers should be identified before fitting a model but multivariate outliers, if present, are identified once the model of best fit is obtained. Outliers that cause a poor fit degrade the predictive value of the regression model; however, this has to be balanced with loss of generalizability if the points are omitted. Multivariate outliers are data values that have an extreme value on a combination of explanatory variables and exert too much leverage and/or discrepancy (see Chapter 5). Data points with high leverage and low discrepancy have no effect on the regression line but tend to increase the R square value and reduce the standard errors. On the other hand, data points with low leverage and high discrepancy tend to influence the 238 Chapter 7 Histogram dependent variable: weight (kg) Mean = 1.

Data points with both a high leverage and a high discrepancy influence the slope, the intercept and the R square value. Thus, a model that contains problematic data points with high leverage and/or high discrepancy values may not generalize well to the population. Multivariate outliers can be identified using Cook’s distances and leverage values as discussed in Chapter 5. Mahalanobis distances are evaluated using critical values of chi-square with degrees of freedom equal to the number of explanatory variables in the model.

Drainage may be obtained during the removal of the cause 250mg amoxil, for example 250 mg amoxil with mastercard, a dental extraction buy 500mg amoxil, or may precede definitive treatment if this makes management easier, for example, incision and drainage of a submandibular abscess. When an extraoral incision is made it is made in a skin crease parallel to the direction of the facial nerve. Once skin has been incised the dissection is carried out bluntly until the infection has been located. Locules of infection are then ruptured using blunt dissection and a drain secured to the external surface. Any pus should be sent for culture and sensitivity testing to the microbiology laboratory. It is important to remember that acute infections are painful and that analgesics, as well as antibiotics, should be prescribed. Similarly, it is important that a child suffering from an acute infection is adequately hydrated. If the infection has restricted the intake of oral fluids due to dysphagia then admission to hospital for intravenous fluid replacement is required. Autotransplantation of teeth in children may be considered as a treatment for the following: (1) repositioning of an ectopic tooth; (2) replacement of an unrestorable tooth with a redundant member of the dentition. The ectopic tooth most commonly repositioned by surgical means is the unerupted, palatally placed, upper permanent canine. An example of using autotransplantation as a means of tooth replacement is the substitution of an upper incisor that is undergoing resorption by a premolar tooth scheduled for extraction as part of an orthodontic treatment plan (Fig. The management regimen for both treatments is similar and is as follows: (1) assessment of donor tooth and recipient site; (2) atraumatic extraction of donor tooth; (3) preparation of recipient site; (4) transplantation; (5) splinting of transplanted tooth; (6) root treatment of transplanted tooth. In addition, when autotransplantation is used to replace a tooth in the arch some coronal preparation and orthodontic movement of the donor tooth may be required. Transplantation surgery is usually performed under antibiotic prophylaxis (either oral or intravenous amoxicillin (amoxycillin)), as the use of systemic antibiotics has been shown to decrease the incidence of root resorption. Assessment of donor tooth and recipient site The tooth to be transplanted has to be appraised clinically and radiographically prior to surgery. The crown of an erupted tooth can be assessed for caries and its dimensions measured. Donor teeth should have an open apex with at least three-quarters of the root formed. The morphology of unerupted teeth for transplantation can only be determined radiographically. Teeth with severe root curvature are unsuitable for transplantation as it is unlikely they can be removed intact without trauma. In addition, the production of a donor site suitable for a dilacerated tooth may be difficult to produce without damaging neighbouring vital teeth. It is important to evaluate the recipient site both clinically and radiographically. The space available for the transplanted tooth must be assessed in both the horizontal and vertical dimensions. Periapical radiographs will alert the clinician to the presence of any bony pathology or retained dental remnants at the recipient site. Atraumatic extraction of donor tooth It is essential to remove the donor tooth using minimal trauma and avoiding contact with the root surface. Thus when removing an erupted tooth for transplantation the usual rules concerning the application of forceps beaks to the root surface do not apply. Prior to the application of the forceps a scalpel should be run around the gingival margin to the crest of the ridge to sever gingival attachments. When an unerupted tooth is being used as a donor great care must be exercised during its removal. As mentioned earlier, bone removal with hand chisels is less likely to damage the donor than the use of a bur.
