Participants will be assigned to one of three treatment groups: treatment for the child only, treatment for the child and parents, or treatment for all family members. Researchers will collect oral bacterial samples from family members before and after treatment and will monitor close-contact interactions within the household using wearable proximity-tracking devices.\n\nThe study will also collect information about oral health habits, family interactions, and environmental factors that may influence bacterial transmission. By combining bacterial DNA analysis with information about family contact patterns, researchers hope to better understand how oral bacteria are shared within households and whether family-based treatment approaches can reduce bacterial recolonization after dental therapy.\n\nThe results of this study may help improve strategies for preventing childhood tooth decay and gum disease by addressing family-level sources of bacterial transmission.",[70,71,72,73],"Dental Caries","Periodontitis","Oral Microbiome","Bacterial Transmission",[75,76,77,78,79,80,81,82,83,84,85,86,87],"family microbial transmission","Oral microbiome","Plaque recolonization","Pediatric oral health","Real-time proximity tracking","Ultrawide Band (UWB)","Oral bacterial transmission","Intergenerational pathogen transfer","Biofilm disruption","Periodontal disease","Family-based intervention","Microbial source tracking","Oral Health","NOT_YET_RECRUITING","2026-06-25",{"date":91,"type":92},"2026-06-30","ACTUAL",{"date":94,"type":64},"2026-09-30",{"date":96,"type":64},"2028-06-30",{"name":5,"class":6},1]
