Comparison of Short-Term Oral Impacts Experienced by Patients Treated with Invisalign or Conventional Fixed Orthodontic Appliances.

OBJECTIVES: Our objective was to test the hypothesis that thermoplastic clear aligners (Invisalign®; Align Technology, Santa Clara, CA, USA) are more pleasant for patients than conventional fixed orthodontic appliances. SUBJECTS AND METHODS: This was an observational retrospective study in which subjects were matched for age, treatment modality, and the treating orthodontist. A total of 60 adult patients (30 in the Invisalign group and 30 in the conventional buccal fixed appliance group) who met the inclusion criteria completed a validated self-reporting questionnaire, rating their experience after appliance activation in regard to oral impact experience and satisfaction of both treatment modalities. Categorical variables were compared using the χ2 test, Fisher's exact test, and the Z test. Continuous variables such as pain level and age were analyzed using the 2-sample t test. RESULTS: Patients on clear aligner therapy reported significantly more difficulty in speech (p = 0.035) necessitating change in speech delivery (p = 0.003). In addition, they reported better chewing ability (p < 0.001), no restrictions on amounts or types of food (p = 0.02), and less mucosal ulcerations (p = 0.01). Effects on daily routine, use of analgesics, and overall treatment satisfaction were not significantly different between the 2 groups. CONCLUSION: Clear aligner therapy is not necessarily more pleasant, but it is more tolerable as it satisfies patient needs over food consumption and absence of mucosal ulcerations. However, clear aligners affect pronunciation and speech delivery in the short term.

Knowledge and Sociodemographic Determinants of Emergency Management of Dental Avulsion among Parents in Kuwait: A Cross-Sectional Study.

OBJECTIVES: The aim of this study was to evaluate the knowledge of first aid measures for a permanent tooth avulsion among parents in Kuwait and to assess the effect of different sociodemographic characteristics. MATERIALS AND METHODS: A cross-sectional study was conducted among 554 parents who visited 5 dental specialty centers in Kuwait. Parent sociodemographic data and responses to avulsion management questions were collected through a self-administered questionnaire. Descriptive and binary logistic regression analyses were used for data analysis. RESULTS: In the 554 responses from patients, gaps were identified in the following areas: replantation (199, 35.9%), cleaning of the tooth (182, 32.9%), and transport media (84, 15.2%). Most parents demonstrated satisfactory knowledge levels regarding the urgency to seek professional help (391, 70.6%) and the first place of contact after the injury (525, 94.8%). Having previous information on emergency management of dental avulsion was a significant predictor of good knowledge (OR 2.138, 95% CI 1.347-3.395, p = 0.001). Of the 544 parents, 99 (17.8%) had received information on dental avulsion management: 30 (30.3%) from the Internet, 19 (19.2%) from books, 12 (12.1%) from television, 6 (6%) from smart phone applications, 2 (2%) from newspapers, and 30 (30.3%) from other sources. CONCLUSION: In this study, parents in Kuwait did not have adequate knowledge of emergency management for dental avulsion. Future educational campaigns on dental avulsion are urgently needed to educate parents.
