A Chinese version of the ECOHIS was developed and demonstrated acceptable validity and reliability. These findings can enable assessments of pre-school child oral health-related quality of life in Chinese speaking communities.

The Chinese version of ECOHIS is sensitive and responsive to dental treatment of ECC under GA.

Countries with more physicians and more dentists were more likely to have ECC data. Among those with data, countries with higher economic growth had higher ECC prevalence.

The oral health-specific measure, ECOHIS, shows better discriminant property between children with S-ECC and caries-free children than the generic measure, PedsQL 4.0. The ECOHIS appears more sensitive than PedsQL 4.0 in assessing the impact of dental caries on the life quality of preschool children.

GDPs and PDs have different dental care approach patterns for pre-school children with dental caries. Wide variation in the views about the best way to treat the child exists within both groups.

BackgroundThis study aims to develop consensus evidence-based clinical guidelines for caries prevention and management by caries risk assessment for pre-school children in Hong Kong.MethodsEmploying the ADAPTE process, guidelines for caries prevention and management by caries risk assessment for pre-school children with a preliminary list of 91 recommendations was complied. External review of the guidelines was conducted by a panel of 41 reviewers from the Hong Kong Society of Paediatric Dentistry using a two-round web-based Delphi process. The reviewers were invited to contribute any comments on the draft-adapted guidelines and rated their agreement with each recommendation using a 9-point Likert scale. During the second round, 36 participants received anonymous feedback from the first round and assessed a narrowed list of 28 recommendations. Recommendations were retained and classified according to the median score and rating percentages by the reviewers.ResultsA total of 70 out of 91 recommendations were retained (five reached high consensus, 65 reached consensus), and 21 recommendations were discarded. Recommendations and guidelines were outlined.ConclusionsCaries prevention and management guidelines for pre-school children were developed for use in Hong Kong using the ADAPTE process and Delphi consensus to develop evidence-based recommendations. This can facilitate the translation of guidelines into dental practice.
