Redesign of an informed consent form to increase participation in a school-based dental program.

Objectives: The study aimed to determine if modifications to the design of a consent form and consenting process increased participation rates in the Indiana University School of Dentistry's Mobile School-Based Dental Program (Seal Indiana).

Methods: Kaizen methodology was followed to identify problem areas in the consenting process. Additionally, stakeholders were invited to participate in focus groups and fill out surveys to identify issues preventing participation in the Seal Indiana program (N = 48) and later to evaluate the changes made (N = 48).

Fluoride Content in Foods and Beverages From Mexico City Markets and Supermarkets.

Background: Sources of fluoride exposure for Mexicans include foods, beverages, fluoridated salt, and naturally fluoridated water. There are no available data describing fluoride content of foods and beverages consumed in Mexico.

Objective: To measure the content of fluoride in foods and beverages typically consumed and to compare their content to that of those from the United States and the United Kingdom.

Retention of dental sealants placed on sound teeth and incipient caries lesions as part of a service-learning programme in rural areas in Mexico.

Background: Dental sealants are an effective treatment for the prevention and management of caries.

Objective: To determine the retention of sealants placed in a rural setting in Mexico as part of an international service-learning (ISL) programme and to determine associations between dental sealant's retention and caries diagnosis at the time of sealant placement.

Methods: Children aged 6-15 were examined for dental caries, received sealants by dental students as part of an ISL programme, and were re-examined 4, 2, or 1 years after placement to assess sealant survival.
