Guidelines are systematically developed evidence-informed statements, including recommendations for clinical practice or public health policy.1,2 Guidelines are fundamental to translate and transfer scientific knowledge to patients, caregivers, clinicians, policy-makers, and other decision-makers.3 Ultimately, the optimal development, dissemination, and implementation of high-quality guidelines may improve the performance of health systems and enhance health outcomes.4
Recommendations or actionable statements contained in guidelines should be developed using systematic and transparent methods to identify and synthesize available evidence, as well as engage stakeholders and agreed upon recommendations.5 In the medical field, there is a wide consensus about well-conducted systematic review being the most reliable approach to synthesizing trustworthy evidence, and a considerable number of frameworks for addressing evidence to decision process are available,6 such as the GRADE-EtD framework7 (Grading of Recommendations Assessment, Development, and Evaluation - Evidence to Decision).
Multiple organizations worldwide, including scientific societies, professional associations, and Ministries of Health, produce guidelines to support dental practice and inform public oral health decisions. However, these organizations rarely follow appropriate methodologies, leading to guidelines with suboptimal quality.8–12 Despite the availability of standards and definitions for the different types of actionable statements contained in guidelines, policy guidance, and similar standards-setting documents in medicine,3 there is a vast set of terminologies used to categorize these documents among organizations developing evidence-informed guidelines in oral health globally. Such misclassification could hinder interprofessional communication and medical and dental care integration.
Developing high-quality healthcare guidelines is a complex and time-consuming process.2 However, there is growing demand from stakeholders globally in oral health for these products. In 2022, the World Health Organization officially approved and adopted the Global oral health strategy, which states that evidence-informed policies of cost-effective interventions must be developed and implemented to influence global and national oral health outcomes. The document also highlighted the importance of translating research findings into practice, including the development of regionally specific, evidence-informed guidance.13
Oral diseases are a global public health problem and decrease the quality of life and well-being of those affected. As the most prevalent diseases, such as dental caries, periodontal diseases, and oral cancer, are mostly preventable; high-quality guidelines to address oral diseases with evidence-informed, cost-effective, and safe interventions are much needed.14 To make the needed improvement to ensure that high-quality guidelines are available for all relevant oral health conditions, this systematic survey is a first step towards knowing the organizations that generate these documents worldwide and comprehensively understanding how such guidelines are been developed.
This systematic survey aims to identify organizations developing guidelines in oral health globally, and describe methods and processes used to formulate actionable statements.
We will include organizations that regularly develop guidelines in oral health, such as scientific societies, Ministries of Health, professional associations, non-governmental organizations, or any working group. For the purpose of this study, we will consider a ‘guideline’ any document or information product containing actionable statements that recommends or suggests a particular course of action for clinical practice or public health policy.1,2
Within the term ‘guideline’, we will consider clinical practice guidelines, guidances, and similar policy documents that enhance the decision-making process, by translating research findings into actionable statements for healthcare practice, public health or policy decisions at the local (national or sub-national level), regional, or global level, and for a diverse group of stakeholders, including but not restricted to patients, healthcare professionals, researchers, institutions, or organizations.1,2,4,5,15
To be included, organizations worldwide must fulfill the following criteria:
• Produce at least three guidelines on any oral health topic since 2012, according to the oral health definition provided by the FDI World Dental Federation and the WHO.16,17
• Produce guidelines that explicitly declare the inclusion of research evidence in its development processes, regardless of whether the organization performs a de novo systematic review, uses pre-existing systematic review, or conducts non-systematic literature reviews to support its decisions.
Organizations that solely produce educational documents or health system policy documents (documents containing actionable statements related to service delivery, health workforce, health information systems, access to essential medicines, vaccines, technology, financing, and leadership or governance) will be excluded.
To identify organizations responsible for guideline development in the field of oral health globally, we will perform both a systematic and manual search. First, we will systematically search for oral health guidelines in electronic databases (PubMed, Epistemonikos database) and guideline repositories, including the Clinical Practice Guidelines (CPG) Infobase, the International Guidelines Library from the Guideline International Networks (GIN), the Guideline Central, the Alliance for the Implementation of Clinical Practice Guidelines (AiCPG) and the Medical Information Distribution Service (Minds) database. We will not limit the search by language or publication status, but the date will be restricted (2012-present). Two reviewers will independently evaluate whether the documents identified are eligible, according to our definition of a guideline. Any disagreements will be resolved with discussions between the independent reviewers. If consensus cannot be reached, a third reviewer (FV-P), will resolve disagreements. The organizations’ names could be collected from various sources, such as the corresponding authors’ information, the supporter/funder organization, or the methods section of the identified document.
In parallel, we will perform a manual search on the websites of guideline developers, scientific societies, professional associations, and ministries of health globally. In addition, we will consult with experts in the field to identify missing organizations that meet the inclusion criteria.
Two reviewers will independently evaluate whether the organizations detected by systematic or manual search are eligible for inclusion in this study, according to the predefined criteria outlined above. The Figure 1 shows the flowchart of the organization’s search and selection. The electronic databases search strategy, the sources used, and the consulted websites are listed in the extended data (Extended data 1).
After an initial calibration exercise, two trained reviewers will extract data independently, using a previously piloted standardized form. Calibration will consist of performing the complete data extraction of two different organizations. Disagreements will be solved through discussion and consensus or with the help of a third reviewer. The data extraction will be divided into three phases: a) Organization level, b) Guidelines or policy documents level, and c) Actionable statement level (Figure 2).
1) Organization level
The form will cover information on the main characteristics of the included organizations, including the organization type (e.g, non-governmental organization, governmental organization, or academic and research institution), country, language, oral health clinical specialty, number of documents produced over the last ten years, and the types of documents produced. The oral health clinical specialty will be classified according to the list and definition of the recognized dental specialties approved by the National Commission for the Recognition of Dental Specialties and Certification Boards of the American Dental Association (ADA)18 and the European recognized dental specialties.19 Regarding the types of documents, we will extract the document name and their description, according to the information provided by the organization (e.g, an organization produces “Clinical Guidelines”, defined as recommendations for clinical practice based on a systematic review of the evidence, along with an assessment of the benefits and possible harms of alternative dental care options, and the same organization also produces “Oral Health Policies”, defined as evidence-informed statements relating to the organization positions on various public health issues). We will categorize these documents into the following categories: 1. Clinical practice guidelines, 2. Public health guidelines, 3. Health products policy and standards (including Health Technology Assessment and Policy statements), and 4. Other, according to the following definitions:
Guidelines: Corresponds to any product that includes systematically developed statements recommending or suggesting a particular course of action for clinical practice or public health decisions. Recommendations are actionable statements designed to help end-users make informed health decisions related to clinical interventions, diagnostic tests, or public health measures to achieve the best individual or collective health outcomes.1,2,5
Policy statements: evidence-informed statements addressing issues of concern and importance to the public health community. “Policy statements should describe and endorse a defined course of action, ranging from legislation and regulations desired to needed new policies of non-governmental organizations and private enterprises”.20
Health technology assessment: “Health technology assessment (HTA) refers to the to the systematic evaluation of health technology’s properties, effects, and/or impacts. It is a multidisciplinary process to evaluate the social, economic, organizational, and ethical issues of a health intervention or health technology. The main purpose of conducting an assessment is to inform a policy decision-making. Considering the definition of health technology, as the application of organized knowledge and skills in the form of medicines, medical devices, vaccines, procedures, and systems developed to solve a health problem and improve quality of life”.21
2) Guidelines or policy documents level
For each document type produced by a single organization, we will extract the information about the main characteristics of the guideline documents, as well as characteristics of the methodology, including the intended users, stakeholders’ involvement, information about the working group or panel composition, conflicts of interest (COI) management policy, and sources of funding. For example, if an organization produces more than one document type with a distinct methodology (for example, a Ministry of Health produces clinical practice guidelines and policy statements), we will extract the data for each document type independently. If this information has changed over the years, we will extract the data from the latest published document.
Finally, we will use the taxonomy developed by Lofti et al. to classify the statements types used within guidelines, to determine which guideline or policy document contains formal recommendations. A formal recommendation is an actionable statement about the selection between two or more interventions in a specific population and, if applicable, in a particular setting. These statements are the results of a structured process, and they are explicitly linked to the evidence resulting from a systematic literature search and appraisal process.3
3) Actionable statement level
We will extract the development process information of the formal recommendations contained in the guidelines. The extraction form will cover information on the type of methodological handbook used (e.g., International organization handbook, In-house handbook), the methods for searching and identifying the research evidence (e.g., systematic review, non-systematic literature review), and information about the evidence-to-decision (EtD) process, including the use of frameworks (e.g., GRADE-EtD, the Scottish Intercollegiate Guidelines Network framework, the United States Preventive Services Task Force framework). A framework is defined as any structure of concepts underlying a structured process, in this case, the process of formulating recommendations (EtD process).6
The information from each organization, the document type, and the formal recommendation development processes will be collected from various sources, such as the organization’s official website, the methods section of each guideline, a reference manual, or a methodological handbook. If available, we will include the latest version of the methodological handbook. If the methods for developing formal recommendations have changed over the years, we will extract the data from the latest published document.
Tables 1, 2, and 3 show the characteristics that will be extracted for each organization and document type.

* The list of options is based on the results reported by Meneses-Echavez et al.6 We will add new options if new approaches and frameworks are used in the oral health field.
The results and data will be analyzed using descriptive statistics, including mean and median and their corresponding measures of dispersion. Frequencies and proportions will be calculated for all variables. We have identified a series of taxonomies, for example, to classify how the organizations describe their methodology to assess the certainty of the evidence, the determination of the direction and strength of actionable statements, and frameworks to move from the evidence to the decisions. These taxonomies will be reviewed and updated in an iterative process as new categories emerge (Tables 2 and 3). Data will be presented in text and tables using narrative synthesis.
We will use the synthesized quantitative and qualitative data to produce a series of recommendations to improve the production of oral health guidelines worldwide. These recommendations will be formulated in a panel meeting including experts in the conduct of evidence synthesis and the creation of guidelines and policies. This group will include epidemiologists, statisticians, methodologists with expertise in systematic reviews and meta-analysis, experts trained in the use of the GRADE approach, investigators with expertise in patients’ values and preferences elucidation, policymakers, and a patient partner member.
Scant information is available about how guidelines are being developed in the oral health field worldwide. Guidelines and policy documents available are dispersed in different sources, and there is a lack of coordination and dialogue among the different institutions, leading to wasted resources.
This systematic survey will synthesize the main characteristics and the methodology used by organizations dedicated to guideline and policy development to formulate actionable statements in oral health. This is the first study that seeks to identify the organizations responsible for developing oral health policies and guidelines worldwide, as well as describe the processes and methods followed.
By summarizing this information, we will gain insight for future assessment of potential barriers to and facilitators for using research evidence and applying EtD frameworks in these documents. This study will provide a foundation for the future development of a sustainable and connected collaborative network for evidence-informed guidelines and policies in oral health globally. The results will be disseminated through peer-reviewed publications, conference presentations, and targeted dissemination of findings with the identified organizations and other stakeholders in the area of clinical and policy decision-making. Our systematic survey represents an important first step toward informing the adoption and creation of standardized processes for the development of oral health policies and guidelines that meet current methodological standards in the medical field. This goal further contributes to the dental and medical integration paradigm.
