BACKGROUND AND AIM: In this manuscript, fluoride releasing dental materials controlling demineralization in fixed orthodontic patients, and the current strategies to prevent white spots were evaluated.METHODS: General literature review was carried out in SciVerse ScienceDirect databases. The search strategy included the terms from Medical Subject Headings (MeSH) created by National Library of M...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
One of the most important concerns of patients is the need for orthodontic treatment, is the long duration of treatment and pain and discomfort during treatment.

Angle, Tweed, and Moyers classified Class III malocclusions into 3 types: pseudo, dentoalveolar, and skeletal. Clinicians have been trying to identify the best timing to intercept a Class III malocclusion that develops as early as the deciduous dentition. With microimplants as skeletal anchorage, orthopedic growth modification became more effective, and it also increased the scope of camouflage...
Our aim was to evaluate the long-term treatment outcome of a systematically applied orthodontic screening and early treatment strategy in a public dental health care system, with special reference to occlusal stability at least 5 years post-retention. The subjects (N = 68) belonged to one age cohort born in a Finnish rural municipality (N = 85), and they were regularly followed from 8 to 20 yea...

BACKGROUND AND AIM: Clinical indices that determine the need for orthodontic treatment do not provide information about the impact of malocclusion on the quality of life. The present study was carried out to assess the correlation between the aesthetic component of the Index of Orthodontic Treatment Need (IOTN) and the Child Perception Questionnaire (CPQ11-14) in determining the need for orthod...
background: orthodontic therapy has oral ecological changes causing increased numbers of mutans streptococci in saliva and plaque. the purpose of this study was to estimate counts and colonization pattern of streptococcus mutans after application of fixed orthodontic appliances. materials and methods: plaque samples of randomly selected sixty patients were collected before placement of orthodon...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
