Prevalence and Risk Factors of Bruxism in a Selected Population of Iranian Children

ABSTRACT Objective: To investigate the prevalence of bruxism in Iranian children aged 6 to 12 years. Material and Methods: This cross-sectional study was conducted on 600 schoolchildren aged 6-12 years. The questionnaire consisted of two sections: the first section included demographic information, while the second evaluated the occurrence of bruxism. Kruskal-Wallis, Chi-Square, Fisher and Multinomial logistic regression were used. A level of p<0.05 was considered statistically significant. Results: 698 questionnaires were distributed, of which 600 participants were returned. According to Multinomial logistic regression, awake bruxism was associated significantly with the following variables: age, sequence of birth, recurrent headache, gastrointestinal disease, nasal obstruction, neurological disorder, easy child crying, sleep disorders, talking in a dream and snoring and jaw disorder. Sleep bruxism was associated significantly with age, premature birth, allergy, gastrointestinal disease, drooling, mouth breathing, nasal obstruction, oral habit, nail biting, sleep disorder, jaw disorders, and family history. Conclusion: Pre-birth and post-birth factors play an important role in the prevalence of bruxism in society. It is possible to prevent complications of bruxism by informing parents and making a timely diagnosis. Parents should be aware of this occurrence to reduce possible related factors to teeth and the masticatory system.

Clinical and Radiographic Success Rates of Pulpotomies in Primary Molars Treated with Formocresol, BiodentineTM, and Endo Repair: A Randomized Clinical Trial

ABSTRACT Objective: To compare the clinical and radiographic success rates of formocresol, BiodentineTM, and Endo Repair agents in primary molars after 12 months. Material and Methods: This randomized double-blind clinical trial was conducted on healthy children referred to the Department of Pediatric Dentistry, Kerman, Iran, in 2018. One hundred twenty children (human primary molar teeth) aged 3-9 years were selected and randomly divided into three interventions (with pulpotomy medicament agents), including formocresol, BiodentineTM, and Endo Repair. All pulpotomized teeth were restored using stainless steel crowns and evaluated clinically and radiographically during a 12-month follow-up. Fisher exact test was used to determine the association of categorical variables and the data were analysed with SPSS 25. Results: All the available teeth in formocresol and BiodentineTM groups obtained clinical success, whereas 62.5% of the Endo Repair group was successful in this regard. Radiographic success rates of the formocresol, BiodentineTM, and Endo Repair groups were 94.7%, 70%, and 28.1% after a 12-month follow-up, respectively. Moreover, pulp canal obliteration was observed in 26.3%, 25%, and 12.5% of the formocresol, BiodentineTM, and Endo Repair groups. Conclusion: This study reported a high rate of clinical success using both BiodentineTM and formocresol pulpotomy techniques. However, the radiographic success rate of formocresol was higher than that of BiodentineTM, and Endo Repair was not considered a suitable pulpotomy medicament agent.

Oral Manifestations and Dental Management Considerations of Lipoid Proteinosis: A Case Report and Review of Literature.

Lipoid proteinosis (LP) is a sporadic congenital metabolic disorder characterized by deposition of hyaline material in various organs. It has a very low prevalence rate of approximately 300 cases reported up to now. It has a vast spectrum of manifestations ranging from asymptomatic skin lesions to the rare but life-threatening laryngeal obstruction. The knowledge of the clinical features of the disease such as hoarseness of voice from infancy, mucocutaneous manifestations, moniliform blepharosis (multiple, beaded papules along the eyelash line) and dental anomalies such as hypoplasia or aplasia of teeth may help oral health care practitioners improve the quality of their patient's life. This case report describes a typical 10-year-old boy who presented to the Department of Pediatric Dentistry, Faculty of Dentistry, University of Medical Sciences, Kerman, Iran with the typical recurrent skin and mucosal lesions, hoarseness, and blepharosis. In addition, he stated a gradual hearing loss, which is not reported as a common manifestation. Moreover, psychosocial issues regarding his appearance and quality of voice had led to absenteeism from school. A punch biopsy obtained from a lesion on his forearm revealed the characteristic histopathological view and directed to the diagnosis of lipoid proteinosis. Dental treatment was initiated with focus on preventive dentistry due to the restricted mouth opening, which was expected to get worse overtime. There is no definitive cure for this disease and the treatment is symptomatic in most cases. A proper workup can result in early diagnosis and management of dental complications, which are difficult to control due to restricted mouth opening, which may significantly affect the patient's social life.

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).

Baby-Risk of malocclusion assessment index: An assessment tool for preventive orthodontic treatment needs in a selected population of children in southeast of Iran.

CONTEXT: Preventive orthodontic treatments are performed in the primary or mixed dentition period and provide a proper development of occlusion to avoid dentofacial anomalies. AIMS: This study aims to evaluate the Baby-Risk of Malocclusion Assessment Index (ROMA) index regarding ease of use, reproducibility, and the epidemiological assessment of major orthodontic problems in children aged 4-6-year-old in Kerman (Iran) kindergartens. SETTING AND DESIGN: This cross-sectional study was conducted on 1000 children aged 4-6 in Kerman (Iran) kindergartens, selected by cluster sampling, and data were collected using the Baby-ROMA index. METHODS: After recording a demographic data collection form, the clinical examination of the teeth was carried out by a dental student. The data were analyzed with SPSS 18 using t-test, analysis of variance, Chi-squared test, and Mann-Whitney test at a significance level of P < 0.05. RESULTS: In this study, the most common cause of malocclusion was dental caries (7.5%), followed by crossbite (6.1%). Furthermore, 31.6% of the subjects had one type of malocclusion, and 20.5% needed monitoring the occlusion before the growth spurt, while 11.1% needed immediate orthodontic treatment (mostly 6-year-old children). Moreover, 15.3% of the subjects had systemic problems; 3.4% had craniofacial, 22% had dental, and 2% had functional problems. The prevalence of class I canine relationship in the right canines was 82.32%, with 82.5% on the left side. The prevalence of open bite was higher in females with thumb-sucking habit. CONCLUSION: The Baby-ROMA index presented good reliability and ease of use for evaluating early orthodontic treatment needs in primary and mixed dentition periods.

Prevalence and Associated-Factors for Entamoeba gingivalis in Adolescents in Southeastern Iran by Culture and PCR, 2017.

BACKGROUND: This study aimed to identify the prevalence and potential factors associated with Entamoeba gingivalis in adolescents in the city of Kerman, southeastern Iran, 2017. METHODS: In this descriptive cross-sectional study, 315 adolescents (mean age; 15 yr) consisting of 189 males and 126 females were randomly selected. For each adolescent, two specimens were collected for culturing and examination by polymerase chain reaction (PCR). Univariate and multivariate logistic regression models were performed to explore any association with demographic and clinical variables. RESULTS: The prevalence of E. gingivalis was 11.7%. Totally, 30 (15.9%) males and 7 (5.6%) females were infected with E. gingivalis. The rate of infection in males was 2.8 times higher than that in females (P<0.001). Statistical analysis identified 4 major factors including sex (OR=4.12, P<0.001), gingival index with severe inflammation (OR = 50, P<0.001), Candida spp. infection (OR=4.41, P<0.001) and decay-missing-filled teeth [DMFT (OR=3.27, P<0.001)]. In contrast to the aforementioned factors, adolescents with history of antibiotic consumption were significantly protected from E. gingivalis infection (OR= 3.24, P<0.001). Culture media detected 9.2% (n= 29), whilst PCR identified 11.4% (n= 36) of infection. CONCLUSION: The present findings clearly demonstrate a positive association between E. gingivalis and distinct demographic and clinical risk determinants. Therefore, dental practitioners and health surveillance personnel should be aware of these confounding factors to rigorously detect and critically manage oral health issues in school-age children in order to prevent or at least minimize the eventual periodontal complications in later life.

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.

A Survey of Knowledge, Attitude and Practice of Iranian Dentists and Pedodontists in Relation to Child Abuse.

STATEMENT OF THE PROBLEM: Since almost half of the child abuse cases affect the head and neck region, dentists have an important role in the diagnosis and report of oral and dental aspects of child abuse cases. PURPOSE: The objective of the current study was to evaluate the knowledge, attitude and practice of the general dentists and pedodontists regarding child abuse and child neglect. MATERIALS AND METHOD: This cross-sectional study was carried out on the participants of the 12th congress of pedodontists of Iran. A self-administered questionnaire was used for evaluating their knowledge, attitude and practice toward child abuse. T-test and ANOVA were applied to analyze the data by SPSS software. p <0.05 was considered statistically significant. RESULTS: The mean score of knowledge, attitude and practice of the participants regarding child abuse was 10.24±2.68, 41.54±11.24 and 2.78±1.05, respectively. The knowledge of pedodontists was significantly higher than knowledge of general dentists. No statistically significant difference was observed in attitude and practice (p> 0.05). CONCLUSION: Dentists had a moderate knowledge, poor attitude and moderate practice regarding child abuse. Considering this fact, improvements in child abuse education for undergraduate students and continuing post-graduate training in this field are recommended.

Clinical, Radiographic, and Histologic Evaluation of Regional Odontodysplasia: a Case Report with 5-year Follow-up.

Regional odontodysplasia is a developmental anomaly that affects the primary and permanent dentitions. This disorder is generally localized in only one arch and its etiology is still unknown. Clinically, the affected teeth have an abnormal morphology and are typically discolored. Radiographically, these teeth show a ghost-like appearance. This paper reported the results of radiographic, histologic and laboratory findings about the case of a 5-year-old girl presenting this rare anomaly. Her familial history was negative for any genetic anomaly, regional odontodysplasia or other dental anomalies. The patient's general health was good and no congenital or acquired disease was reported. She was kept under follow-up care until she reached the age of 10 years. Panoramic radiograph showed the involvement of permanent teeth on the right maxillary quadrant. The affected edentulous quadrant was rehabilitated with temporary acrylic maxillary partial denture. The presentation of this case would hopefully have valuable information for pediatric dentists to review the clinical and radiographic features of regional odontodysplasia, yet expediting the diagnosis and treatment of patients with this condition.
