ABSTRACT
@#Increasing numbers of adult patients are seeking orthodontic treatment, which increases the need for orthodontists to treat malocclusion in periodontally compromised teeth affected by periodontitis. It is essential to control active inflammation prior to initiating an orthodontic protocol to avoid further breakdown of alveolar bone caused by periodontitis. However, whether the condition of periodontal ligaments can completely recover to a normal condition after controlling inflammation and tolerate orthodontic tooth movement remains controversial. The present review elaborates, from clinical trials (macroscopic) to biological tests (microscopic), the characteristics of periodontal tissue and periodontal ligament cells with a history of periodontitis that are submitted to orthodontic force loading. The following conclusions are made: 1. Orthodontic treatment in periodontally compromised patients is unusual because of changes in periodontal condition. 2. The combination of orthodontic force loading and uncontrolled periodontal inflammation aggravates pathological bone resorption; therefore, it is crucial to perform periodontal therapy prior to orthodontic treatment. 3. The periodontal ligament can withstand proper mechanical force loading after periodontal treatment. 4. Orthodontic treatment, as an adjunctive therapy, can improve periodontally compromised tissue and pathological tooth movement.
ABSTRACT
Objective:To identify the influence of personality characteristics on adult patients' satisfaction after initial orthodontic treatment and offer references to rise quality of orthodontic treatment.Methods:85 patients(34 males and 51 females;average age 23.3years?4.4years who treated their teeth by fixed orthodontics were included in the study.Satisfaction questionnaire was used to assess the satisfaction with the dentition in the study sample.The NEO Five Factor inventory was used to assess personality profiles and traits in the study samples.Comparisons between groups were made by using Logarithm of likelihood ratio test.Results:This test provides a comprehensive assessment of personality according to the five major domains namely Neuroticism,Extroversion,Openness,Agreeableness and Conscientiousness.Satisfaction of higher neuroticism scores is relative low(P0.05).Conclusion:Different personality traits were found to be correlated with adult patients' satisfaction with their dentition during initial orthodontic treatment.The orthodontists should pay more attention to higher neuroticism scores adult patients during treatment.In according to strengthen the communication between the orthodontists and outpatients,the therapeutic effect of adult orthodontic treatment could be increased.
