Objective: Chemotherapy and radiotherapy, used to treat childhood hematological malignancies (acute lymphocytic leukemia [ALL] and acute myelocytic leukemia [AML]) can negatively affect oral tissues and organs. This study aimed to evaluate the oral health‐related quality of life in children with ALL/AML. Materials and Methods: A total of 99 children, including 49 undergoing ALL/AML (41 with ALL and eight with AML) and 50 healthy volunteers, were included in this cross‐sectional study. The mean age of the entire study group was 78.63 ± 34.41 months. The mean age of the ALL/AML and control groups was 87.12 ± 35.04 and 70.95 ± 34.85 months, respectively. The Simplified Oral Hygiene Index (SOHI), the Decayed, Missing, and Filled Teeth (DMFT/dmft) index, and the Turkish version of the Early Childhood Oral Health Impact Scale (ECOHIS‐T) were administered to all children. The data were analyzed using SPSS software (version 22.0). The Pearson chi‐square and Fisher's exact tests were used to compare demographic data. Results: The age and gender distributions of the two groups were similar. According to ECOHIS‐T, the children in the ALL/AML group had significantly more loss of function (eating, drinking, sleeping, etc.) than those in the control group. Conclusions: Oral health and self‐care were negatively affected by childhood ALL/AML and its treatment. [ABSTRACT FROM AUTHOR]

Aim: To assess trends and seasonal variation of dental trauma by using the Google Trends data. Design: Google Trends was used to obtain relative search volume (RSV) of search terms such as dental trauma, broken tooth, chipped tooth, knocked‐out tooth, avulsed tooth, and gum trauma. The search strategy was set to the time period (January 2004 to December 2019), region (worldwide, the United States, the UK, Australia, Canada, New Zealand, Ireland, and Turkey), Web search, and all categories. Seasonal variation was evaluated using the cosinor analysis. Results: The worldwide RSV values of broken tooth, chipped tooth, knocked‐out tooth, and avulsed tooth have shown a general increase in recent years with an upward forecast line. The RSV values of dental trauma have shown a general increase in recent years with a plateau forecast line, and gum trauma has shown a stable trend with a plateau forecast line. Seasonal variation of chipped tooth, broken tooth, dental trauma, knocked‐out tooth, avulsed tooth, and gum trauma was not found statistically significant in any of the countries (p >.025). The top related queries of chipped tooth and broken tooth were about pain, fix/repair, and cost. The top related topics for avulsed tooth and knocked‐out tooth are about infant, child, toddler, and primary tooth. Conclusions: People's interest on dental trauma, broken tooth, chipped tooth, knocked‐out tooth, and avulsed tooth has shown a general increase in recent years without showing a seasonal pattern. Healthcare professionals should pay more attention to people's concerns and informational needs. [ABSTRACT FROM AUTHOR]
