Prevalence and Distribution of Dental Anomalies in Schoolchildren in Kuwait.

OBJECTIVE: Dental anomalies (DA) can affect paediatric patients' aesthetics, function, and psychological well-being. There is a lack of data about the prevalence of DA in children in Kuwait. This study aimed to investigate the prevalence and distribution of DA amongst schoolchildren aged 8 to 12 years. METHODS: A retrospective study was conducted using panoramic digital radiographs of children who attended a single dental center. All radiographs were evaluated by 2 calibrated and trained examiners. RESULTS: DA were present in 110 (20.1%) out of the 546 panoramic radiographs examined: 53.6% in females and 46.4% in males. The mean age of children with DA (9.83 ± 1.29) was similar to that of children with no anomalies (9.96 ± 1.46). The most prevalent anomaly was dental agenesis (9.3%), followed by taurodontism (6.6%) and ectopic eruption (EE, 2%). DA were more common in the maxilla (58.2%) compared to the mandible (41.8%, P = .042). Congenitally missing teeth were significantly more frequent in the mandible (56.9%) than in the maxilla (43.1%, P = .003). EE was significantly more common in the maxilla (90.9%) than in the mandible (9.1%, P = .024). Microdontia and root dilacerations were only present in males, whilst supernumerary teeth, transposition, and impacted teeth were noted in females only. CONCLUSIONS: The prevalence of DA amongst schoolchildren in Kuwait was considered to be relatively high. Certain DA were associated with gender. The significant prevalence of DA highlights the need for early diagnosis using panoramic radiographs, particularly during the ages of 9 and 10, in order to ensure effective patient management.

Oral health knowledge, attitude and practice among adolescents in Kuwait.

OBJECTIVES: Adequate knowledge about oral health at a young age is essential in establishing good oral health related behaviors and in developing a positive attitude towards oral health. This study aims to assess the oral health knowledge, attitude and practice of adolescent children aged 15-17 years in Kuwait. METHODS: This cross-sectional survey was conducted in 12 randomly selected public schools in Kuwait using a two-stage cluster sampling method. An Arabic questionnaire with 29 questions were distributed to the students from selected classes. The questionnaire was divided into four sections: the first section gathered information on the sociodemographic characteristics of the participants; the second section assessed the oral health knowledge of the respondents; the third section assessed the students' attitude towards professional dental care and the last section assessed the students' oral health behaviors and practice. Frequency distributions were obtained for each variable and the differences between genders were analyzed using chi-squared statistics and the mean difference in the knowledge and attitude scores were analyzed using independent sample t-test. RESULTS: A total of 3,091 students aged 15-17 years (52.8% girls) participated in this study. The mean (SD) knowledge score of the respondents was 8.62 (2.53) and this was significantly higher for girls compared to boys (p<0.001). Significantly higher percentage of girls than boys knew the role of diet and oral hygiene in preventing caries (p<0.001). Knowledge about dental plaque was very limited in this population. Majority of the respondents believed that regular dental visits were essential (87.1%). The mean (SD) attitude score of the respondents was 3.30 (2.72) and this was significantly higher for girls compared to boys (p<0.001). Majority of the students used toothbrush and toothpaste to clean their teeth (60%). CONCLUSION: Significant gender differences were observed in the oral health knowledge and attitudes in this population. School based oral health promotion programs can be effective in promoting good oral health attitudes and practice among children.
