Orthokeratology (also known as Ortho-K) uses an extremely high oxygen permeable corneal mold to temporarily reshape the cornea. The molds are worn while sleeping and taken out upon wakening. This means that your child’s sight will be good during the day hence allowing him/her to go to school, exercise and swim without needing glasses or contact lenses. What can we achieve with Ortho-K? The aim of Ortho-K is to control progression of myopia with the additional benefit of independence from glasses and contact lens in the day.
When a light-cured orthodontic adhesive is used with a metal bracket, it is usually cured only at the incisal and cervical edges.When the adhesive is irradiated directly through a translucent bracket, the degree of cure of the adhesive is influenced by the translucency of the bracket. Self-ligating brackets are defined as "a [dental] brace, which generally utilizes a permanently installed, moveable component to entrap the archwire". Self-ligating brackets have also been designed without a movable component to hold the wire in place. self-ligating (SL) brackets are not something new to orthodontics; they are available from the early 20th century. In the mid 1930s, the Russell attachments were an attempt to enhance clinical efficiency by reducing the ligation time.
The proposed core advantages of self-ligating system19 ● More certain full archwire engagement ● Low friction between the bracket and the archwire ● Greater arch expansion with less incisor proclination ● Faster archwire ligation and removal Particularly, claims that more stable transverse arch expansion with minimal incisor proclination can be achieved with self-ligating systems, offer a paradigm shift in treatment that entails fewer extractions and more arch expansion.17 However, it subsequently raised questions about the stability of results and the feasibility of long-term retention provided by this technique.16 Dwight Damon (1998)17 clarified the dubiety with his philosophy of ‘Bioadaptive response’ and ‘Biozone’. Bioadaptive
The patient’s interview resulted in 535 statements which were reevaluated and the result was 46 unique statements .The statements were divided into 7 conceptual dimensions and three statements were added to cover the handicap dimension. 3.Structure of questionnaire : OHIP questions evaluated on five point Lickert scale, for example when the patient choose there is only the following choices (S.Adulyanon & Sheiham): Occasionally. Hardly ever /never. Very often. Fairly often.
The term functional amblyopia often is used to describe amblyopia, which maybe transformable by occlusion therapy. Organic amblyopia means changeless amblyopia. Majority of vision losses from amblyopia is avoidable or changeable with the proper type of interference. The improvements of vision build upon by mean of mature visual relation are, the period of loss and what age the therapy is started. It is essential to eliminate all organic cause of impaired sightness as various disorders cannot be visible on usual
Table 3 shows the results of the descriptive analysis. When interpreting the results, be advised that the mean can take values between 1 and 7, where proximity to 1 indicates lack of importance and proximity to 7 denotes a high importance attributed. Please note that in the analysis of the last factor - Possibility of parent-children activities, the sample size has been reduced to only those respondents who declared having children in the demographic questions
INTRODUCTION The principal goal of the Prosthodontics is to control oral disease while restoring aesthetics and function with durable biocompatible restorations. Knowledge of the responses of periodontal tissues to fixed partial dentures is crucial role in in the development of treatment plans with predictable prognoses. During diagnosis, treatment planning, and active therapy, each patient’s needs must be considered in light of the available evidence, which includes published clinical trials, anecdotal reports from peers, and personal clinical experiences. Critical evaluation of available evidence should be included in the decision-making processes for a predictable result. The fixed partial denture (FPD) is a common treatment available for
While directly computing the expected value is not possible for most problems, it can be approximated through Monte Carlo sampling in some situations. The expected value, with sample size N, can be approximated by the average of the realizations: E_(ξ∈Ξ) [∑_(p∈P)▒〖o_p .x_p^ξ 〗]≈1/N ∑_(n=1)^N▒∑_(p∈P)▒〖o_p .x_p^n 〗
Results of measures The measurements were subjected to various exploratory factor analyses by using principle components with varimax rotation. Few of the items had loading problems below the accepted cut level of 0.50 and were not logically identified with any of the factors (Heene, M., Hilbert, S., Draxler, C., Ziegler, M., & Bühner, M., 2011). Due to these reasons, one item from E-service quality, one item from Tourists personal income and one item from intention to visit were dropped. The final results suggested a five factor solution with eigenvalues more than 1.0 that accounted for 69.2 percentage of the total variance. In order to obtain more detailed estimations, confirmatory factor analysis using SPSS was enlisted.
3.5 The Analysis A statistical analysis of politeness score level was found out using the test of significance (t-test) and Analysis of variance (ANOVA) to show the significant difference (if any) between the variables. For this purpose SPSS software was used. 3.6 Designing the framework for analysis of speech act patterns : The coding Scheme : The politeness score for request situations were studied and analysed. A politeness score was found out by adding the ratings given for each of the six request situation. The scores will reveal on the whole the extent of politeness among the respondents.
