Impact of Laughter Therapy on Anxiety and Pain in Pediatric Dentistry: A Double-Blinded Randomized, Controlled Clinical Trial

Abstract Objective: To evaluate the effect of laughter therapy on reducing anxiety and pain during dental procedures in children 5-7 years of age. Material and Methods: 48 children aged 5-7 years were included in this cross-over double-blinded clinical trial after the parents completed the Screen for Child Anxiety Related Disorder questionnaire (SCARED). After allocation into two groups: laughter intervention (A) and neutral intervention (B), the anxiety as well as pain were determined by Modified Child Dental Anxiety Scale Faces questionnaire (MCDASF) and the Wong-Baker Faces Scale, respectively. Also, the child's behavior during the treatment was recorded using the Sound, Eye, Motor scale (SEM). Data were analyzed by SPSS 21 using Paired t-test, Independent t-test, Chi-square, Mann-Whitney and Wilcoxon's test. Results: The mean score of anxiety in the laughter intervention group (17.42±2.74) was significantly less than (22.06±2.16) in the neutral intervention group (p=0.000) and lower in boys in both groups (p=0.000, p=0.047). The mean pain severity reported by the children in the neutral intervention group (5.33±1.81) was higher than in the laughter intervention group (2.38±1.87; p=0.00) and higher in girls in both groups (p=0.02; p=0.03). Conclusion: The laughter intervention before dental procedures had a significant effect on reducing anxiety and pain during dental treatment (AU).

Childhood Systemic Lupus Erythematosus; a Rare Multisystem Disorder: Case Report of a 3-year-old Girl with Oral Involvement as a Primary Sign.

Childhood-onset systemic lupus erythematosus (cSLE) is a severe, chronic, multi-organ, and systemic autoimmune disorder characterized by inflammatory and autoimmune reaction in several organs. The occurrence of systemic lupus erythematosus (SLE) in children is very rare. About 20% of all SLE cases are diagnosed during the first two decades of life and the disease is extremely rare before age of 5 years. In this case report, we present a 3-year-old girl presented with SLE symptoms similar to primary herpetic gingivostomatitis. Early diagnosis lead to proper treatment of the disease and it is important to decrease oral complications in children. Diagnosis could be improved by introduce new cases to provide valuable information for dentists based on diagnostic criteria, therapeutic steps and complication of treatment of SLE in Children. Therefore, it could be concluded that dentists involved in pediatric dentistry should consider and work out on the clinical signs of SLE in children with history of oral herpes virus infection.

Ergonomic Evaluation of Dental Professionals as Determined by Rapid Entire Body Assessment Method in 2014.

STATEMENT OF THE PROBLEM: In dentistry, incorrect working posture is the most important cause of musculoskeletal disorders. PURPOSE: The aim of this research was to evaluate the work postures of general dentists and specialists using rapid entire body assessment (REBA) method. MATERIALS AND METHOD: In this cross-sectional study, work postures were assessed in 90 dentists by employing REBA method. Stratified sampling method was used. Data were analyzed by analysis of variance (ANOVA), Independent t-test and Pearson's correlation test in SPSS 19. RESULTS: The results showed that work postures of 90% of dentists were at moderate- to high-risk levels. Among the specialists, periodontists, pedodontists and oral and maxillofacial surgeons had the worst body postures. CONCLUSION: In general, dentists' working postures need improvement and consequently, a more comprehensive ergonomic training and promotion is required in dentistry curriculum at Universities.

Aspergillosis in a Child with Acute Myeloid Leukemia: Complications, and Treatment.

Attention to early diagnosis and multidisciplinary treatment can reduce the wide range of complications of the infection in these patients. This article reports 4-year history of a child with leukemia, who suffered from a rare aspergillosis infection in the palatal region of oral cavity during chemotherapy. Early diagnosis and treatment of bacterial and fungal infections, especially rare types such as aspergillosis, in patients with leukemia is important for reducing widespread complications.
