A full preventive programme must be instituted before any definitive restorations in a child with a high caries rate purchase viagra gold online. Repetitive treatment should be avoided and with careful treatment planning and choice of restorative materials long-lasting restorations can be carried out in children order viagra gold 800mg mastercard. The stainless-steel metal crown is the most durable restoration in the primary dentition for large cavities and endodontically treated teeth effective viagra gold 800mg. Resin-modified glass ionomers and polyacid-modified composite resins may have an increased role in the future in the restoration of primary teeth. Rubber dam should be placed, if at all possible, prior to the restoration of all teeth. Careful evaluation of the state of pulp inflammation should be carried out before the placement of proximal restorations in primary teeth. Wherever the pulp is deemed to be involved, pulp therapy should be carried out prior to the coronal restoration. Formocresol is likely to be replaced with newer, safer medicaments such as Ferric Sulphate. Response of the primary pulp to inflammation: a review of the Leeds studies and challenges for the future. Clinical evaluation of paired compomer and glass ionomer restorations in primary molars: final results after 42 months. The first permanent teeth erupt into the mouth at approximately 6 years of age, but may appear as early as the age of 4. However, the eruption of the first permanent molars largely goes unnoticed until there is a problem. The first permanent molars are teeth that commonly exhibit disrupted enamel; the reported incidence of defects range from 3. The occlusal surfaces of these molar teeth account for about 90% of caries in children. Restoration of the young permanent dentition is part of a continuum and cannot be regarded in isolation. It does nothing to cure the disease and must form part of a much wider treatment modality, which includes identification of the risk factors contributing to the disease followed by introduction of specific prevention counter measures. Efforts must be applied to all of these areas to attempt to provide the optimum conditions for future tooth survival. These risk factors and preventive measures are addressed in other chapters, such that the authors can confine themselves to appraisal of methods of treatment of caries in the young permanent dentition. They cannot hope to completely cover every aspect of operative treatment in one chapter; there are other texts that should be read to give a fuller account of the available techniques (see sections 9. The idea of a caries risk assessment for each child patient is to ensure that the chosen diagnostic tests, preventive treatment, and any provided restorations, are geared specifically to the need of that patient. Factors requiring consideration are: (1) present caries activity; (2) past caries activity; (3) parent /sibling caries activity; (4) sugar consumption; (5) oral hygiene; (6) fluoride exposure; (7) teeth morphology; (8) Streptococcus mutans levels; (9) saliva characteristics, flow rate, and consistency. Factors (1)-(7) will become clear when a full history and examination are carried out; while (8) and (9) will only come into play if there is rampant caries, which the dentist cannot explain from the history (Fig. The operator must keep this to a minimum, consistent with complete caries eradication. Every time an operator places a restoration, he or she destroys more of the original tooth structure, thereby weakening the tooth. Even though the occlusion in a young person changes as growth occurs and teeth erupt, it is important to realize, that when the operator places restorations, he or she must replicate the original occlusal contacts in the tooth. Although, it may be tempting to keep the restoration totally out of the occlusion, teeth will move back into the occlusion, which will thereafter be slightly different and the cumulative effect of a lot of little changes can severely disrupt the occlusion in the long term. When treating an approximal lesion on one tooth with an adjacent neighbour, the operator will almost certainly damage the latter. The important surface layer of the neighbouring tooth, which contains the highest level of fluoride is the most resistant, so damage inflicted increases the chances of the adjacent surface of the neighbouring tooth becoming carious. It also creates an area of roughness on that surface, which in turn will accumulate more plaque, thereby increasing the risk of further decalcification. When placing an interproximal restoration it is inevitable that there is some damage to the periodontal tissues. There is the transient damage caused by placement of the matrix band and wedge, and there is also an enduring effect caused by the presence of the restoration margin. The very presence of the new restoration results in a contour change of the interstitial space. However smooth the operator attempts to make it, the altered state will increase plaque accumulation. Key Point Every time a restoration is placed, more of the original tooth structure will be destroyed, thereby weakening the tooth. There is little evidence to suggest that remineralization occurs in lesions already into dentine. The rate of caries progression is usually slow but can be rapid in some individuals, particularly younger children. In general, the older the child is at diagnosis of a carious lesion the slower the progress of the lesion, assuming constancy of other risk factors. Small restorations are generally more successful than large, so a balance has to be struck, allowing preventive procedures adequate time to function, against the risk of lesion enlargement. The progression rate of approximal caries can vary from tooth to tooth within the same mouth. Remineralization sources available are: • fluoride rinse, • fluoride varnish, • chlorhexidine thymol varnish, • oral hygiene measures, • adjacent glass ionomer restorations. Determination of the most effective method to retard the progression of approximal caries requires not only identification of the most effective remineralizing agent but also the frequency with which to employ it. Key Point The remineralized tissue of early caries is less susceptible to further caries. Existing studies indicate that fluoride varnishes, solutions, and toothpastes all provide a significant effect on the progression of approximal caries in permanent molars when assessed radiographically. It would be interesting to know what happened after the completion of the studies and poses the following questions: • Would the lesions have developed to the restorative stage? Progress of caries through the enamel seems to be fairly slow but once the dentine is reached it accelerates. So as a rule of thumb, restore approximal surfaces once the lesion reaches the enamel/dentine interface. Where there is no overt or open cavity, diagnosing the status of a discoloured or stained fissure can be incredibly difficult if not impossible on occasions. These include: • visual methods (dry tooth); • probe/explorer; • bitewing radiographs; • electronic; • fibre optic transillumination; • laser diagnosis. When two or three methods are used in combination, there is greater accuracy and higher rates of detection of caries.

Logistic regression is similar to the linear regression in that a regression equation can be used to predict the probability of an outcome occurring cheap 800mg viagra gold with visa. However discount 800 mg viagra gold overnight delivery, the logistic regression equation is expressed in logarithmic terms (or logits) and therefore regression coeffi- cients must be converted to be interpreted discount 800 mg viagra gold mastercard. Although the explanatory variables or predictors in the model can be continuous or categorical variables, logistic regression is best suited to measure the effects of exposures or explanatory variables that are binary variables. Continuous variables can be included but logistic regression will produce an estimate of risk for each unit of measurement. Thus, the assumption that the risk effect is linear over each unit of the variable must be met and the relationship should not be curved or have a threshold value over which the effect occurs. Logistic regres- sion is not suitable for matched or paired data or for repeated measures because the measurements are not independent – in these situations, conditional logistic regression is used. In addition, variables that are alternative outcome variables because they are on the same pathway of development as the outcome variable must not be included as independent risk factors. A large sample size is usually required to support a reliable binary logistic regression model because a cell is generated for each unit of the variable. If three variables each with two levels are included in the analysis, for example, an outcome and two explanatory variables, the number of cells in the model will be 2 × 2 × 2, or eight cells. As with chi-square analyses, a general rule of thumb is that the number of cases in any one cell should be at least 10. When there are empty cells or cells with a small number of cases, estimates of risk can become unstable and unreliable. Using this method, variables are added to the model one at a time in order of the magnitude of the chi-square association, starting with the largest estimate. At each step, changes to the model can be examined to assess multicollinearity and instability in the model. If an a priori decision is made to include known confounders, these can be entered first into the logistic regression and the model built up from there. Alternatively, Risk statistics 301 confounders can be entered at the end of the model building sequence and only retained in the model if they change the size of the coefficients of the variables already in the model by more than 10%. At each step of adding a variable to the model, it is important to compare the P values, the standard errors and the odds ratios in the model from Block 1 of 1 with the values from the second model in Block 2 of 2. A standard error that increases by an impor- tant amount, say by more than 10% when another variable is added to the model, is an indication that the model has become less precise. In this situation, the model is less stable as a result of two or more variables having some degree of multicollinear- ity and thus sharing variation. This indicates that the variable added to the model is a good predictor of the outcome and explains some of the variance. As with any multivariate model, the decision of which variable to remove or maintain is based on biological plausibility for the effect and decisions about the variables that can be measured with most accuracy. All people with the disease are 56 years and older and all people aged less than 56 do not have the disease. Therefore, age group 3 predicts the presence of the disease and the age groups of 1 and 2 predict the absence of the disease. Here, the outcome groups (presence or absence of a disease) can be separated by the explanatory variable. Complete separation results in large standard errors as a result of overfitting the regression model. The Cox and Snell R square is similar to the multiple correlation coefficient in linear regression and measures the strength of the association. This coefficient which takes sample size into consideration is based on log likelihoods and cannot reach its maximum value of 1. Consequently, the Nagelkerke R square is generally higher than Cox’s and has values that range between 0 and 1. To evaluate the contribution of an explanatory variable to the model, the Wald statis- tic can be used. This statistic has a chi-square distribution and is the result of dividing the B value by its standard error and then squaring the result. This value is used to cal- culate the significance (P) value for each factor in the model. In logistic regression, the constant is used in the prediction of probabilities but does not have a practical interpre- tation. It should be noted that when the absolute value of the B coefficient is large, the standard error increases which results in the Wald statistic being underestimated. In this case, other methods such as a sequential method of entering variables should be used to assess the contribution of the variable to the model. In this model, the comparison model is no predictors, with only the constant (intercept) included. The Variables in the Equation table shows the model coefficients but the interpretation of the coefficients is different to those obtained in linear regression. A positive coefficient indicates that the predicted odds increase as the explanatory variable increases. A negative coef- ficient indicates that the predicted odds decrease as the explanatory variable increases. When adding further variables to the model, it is important that this standard error does not inflate by more than 10%. This value indicates the changes in odds associated with a unit increase in the explanatory variable and when there is only one explanatory variable in the model is the same as the estimate from the 2 × 2 crosstabulation.

The Omnibus Tests of Model Coefficients table indicates the change in the chi-square value from the previous model and whether this change is significant. The odds ratio for infection, which is the exponential of the beta coefficient (B) 0. The Omnibus Tests of Model Coefficients table shows that the chi-square value has slightly changed, which is not significant indicating that adding gender to the model did not improve the fit of the model. Crosstabs Early infection * Gender Crosstabulation Gender Female Male Total Early infection No Count 1016 1005 2021 % within gender 85. Examination of the Crosstab- ulation tables shows that males have a higher percentage of allergy and early respiratory infections compared to females. Thus, gender was a risk factor in the unadjusted esti- mates because of confounding between gender and the other two risk factors. The logistic regression shows that once the effects of confounding are removed, gender is no longer a significant independent risk factor for diagnosed asthma. Separating out the confounding and identifying the independent effects of risk factors makes an invaluable contribution towards identifying pathways to disease. In this research question, the data were derived from a cross-sectional study and thus it is important to report the proportion of children who had asthma in the groups that were exposed or not exposed to the risk factors of interest as shown in Table 9. In a case–control study, it would be important to report the per cent of par- ticipants in the case and control groups who were exposed to the factors of interest. It is also important to report the unadjusted and adjusted values so that the importance of confounding factors is clear.

If goals are manifestly impossible then parents and child patients become disillusioned viagra gold 800mg low cost. Parents feel that the dentist does not understand their problems and complain that they are being blamed for any dental shortcomings viagra gold 800mg sale. So always ensure that you plan goal setting carefully in a positive and friendly manner purchase genuine viagra gold line. This is the final part of the visit and should be clearly signposted so that everyone knows that the appointment is over. The objective should be to ensure that wherever possible the patient and parents leave with a sense of goodwill. However, the basic element of according the patient the maximum attention and personalizing your comments should never be forgotten. Dentists do not want to be considered as people who inflict unnecessary anxiety on the general public. However, anxiety and dental care seem to be locked in the general folklore of many countries. Many definitions of anxiety have been suggested and it is a somewhat daunting task to reconcile them. If, for example, a person is anxious, then she/he will act in a particular manner. Thus, anxiety should be seen as a multi- factorial problem made up of a number of different components, all of which can exert an effect. Anxiety must also be seen as a continuum with fear⎯it is almost impossible to separate the two in much of the research undertaken in the field of dentistry, where the two words are used interchangeably. One could consider that anxiety is more a general feeling of discomfort, while fear is a strong reaction to a specific event. Nevertheless it is counterproductive to search for elusive definitions as both fear and anxiety are associated with dental visiting and treatment. From a common-sense point of view it is clear that some situations will arouse more anxiety than others. For example, a fear of heights is relatively common, but it is galling to note that in the United States a study by Agras et al. Clearly then, anxiety about dental care is a problem that we as a profession must take seriously, especially as children remember pain and stress suffered at the dentist and carry the emotional scars into adult life. Research in this area suggests that the extent of anxiety a person experiences does not relate directly to dental knowledge, but is an amalgamation of personal experiences, family concerns, disease levels, and general personality traits. Such a complex situation means that it is no easy task to measure dental anxiety and pinpoint aetiological agents. Questionnaires and rating scales are the most commonly used means by which anxiety has been quantified, although there has been some interest in physiological data such as heart rate. A high score should alert the dental team that a particular patient is very anxious. Therefore there has been great interest in measuring anxiety by observing behaviour. One such scale was developed by Frankl to assess the effect of a parent remaining with a child in the surgery (see Kent and Blinkhorn 1991). Another scale which is popular with researchers is one used by Houpt, which monitors behaviour by allocating a numerical score to items such as body movement and crying (see Kent and Blinkhorn 1991). Recent studies have used the Frankl scale to select subjects for studies, and then more detailed behaviour evaluation systems are utilized to monitor the compliance with treatment (see Kent and Blinkhorn 1991). Behavioural observation research can be problematical as the presence of an observer in the surgery may upset the patient. In addition, it is difficult to be totally objective when different coping strategies are being used and some bias will occur. However, few physiological signs are specific to one particular emotion and the measuring techniques often provoke anxiety in the child patient, so they are rarely used. As yet, there is no standard measure of dental anxiety for children as the reproducibility and reliability of most questionnaires have not been demonstrated, plus observational and physiological indices are not well developed. This is a serious problem as the assessment of strategies to reduce anxiety is somewhat compromised by a lack of universally accepted measuring techniques. Uncertainty about what is to happen is certainly a factor, a poor past experience with a dentist could upset a patient, while others may learn anxiety responses from parents, relations, or friends. A dentist who can alleviate anxiety or prevent it happening in the first place will always be popular with patients. Clearly, the easiest way to control anxiety is to establish an effective preventive programme so that children do not require any treatment. Try to see young patients on time and do not stress yourself or the child by expecting to complete a clinical task in a short time on an apprehensive patient. An increasingly popular choice is the use of pharmacological agents; these will be discussed in Chapter 4. The alternatives to the pharmacological approach are: (1) reducing uncertainty; (2) modelling; (3) cognitive approaches; (4) relaxation; and (5) systematic desensitization. Most children will cope if given friendly reassurance from the dentist, but some patients will need a more structured programme. While it is a popular technique there is little experimental work to support its use. Another technique to reduce anxiety among very worried children is to send a letter home explaining all the details of the proposed first visit so that uncertainty will be reduced. Acclimatization programmes gradually introducing the child to dental care over a number of visits have been shown to be of value. This approach is rather time consuming and does little for the really nervous child. You or I might repeat an action if we see others being rewarded, or if someone is punished we might well decide not to follow that behaviour. If a child could be shown that it is possible to visit the dentist, have treatment, and then leave in a happy frame of mind (Fig. It is not necessary to use a live model, videos of co-operative patients are of value. However, the following points should be taken into consideration when setting up a programme. The model should be shown entering and leaving the surgery to prove treatment has no lasting effect. People may heighten their anxiety by worrying more and more about a dental problem so creating a vicious reinforcing circle. Thus there has been great interest in trying to get individuals to identify and then alter their dysfunctional beliefs. Cognitive therapy is useful for focused types of anxiety⎯hence its value in combating dental anxiety.
