Key Takeaway
The Oral Health Reception and Risk Classification Protocol is valid and reliable for dental emergency triage.

A methodological study conducted at the Dental Emergency Service of the School of Dentistry, Federal University of Uberlândia (PSO-HOUFU) aimed to validate the Oral Health Reception and Risk Classification Protocol. The study included 80 patients and assessed the protocol's content validity, inter-rater reliability, and practical outcomes.

Results showed that 93.75% of patients reported pain upon arrival, highlighting the need for effective triage. Risk classification distribution was 50% yellow and 45% green, with no red or blue classifications reported. The average time between arrival and treatment was 1 hour and 33 minutes, and the dropout rate was low at 2.5%.

Inter-rater reliability was excellent, with 97% agreement (Kappa coefficient). The protocol demonstrated strong content validity in terms of appearance, clarity, and relevance. These findings support the safe use of this protocol by health professionals in dental emergency triage.

The study provides a validated tool for prioritizing dental emergency patients based on risk, potentially improving workflow and patient outcomes. However, as a methodological validation, it does not assess treatment efficacy or long-term outcomes.

Researchers evaluated a specific protocol designed for oral health reception and risk classification. The study looked at 80 patients who visited a dental emergency service to see if the system worked well for sorting patients based on their needs.

The results showed that the system was reliable, with a 97% agreement rate between different staff members. During the study, nearly all patients reported experiencing pain, and about half were classified as yellow risk while 45% were green risk. The average time from arrival to treatment was 1 hour and 33 minutes.

Because this is a methodological study, it focuses on how well the triage system works rather than the outcome of dental treatments. It confirms that the protocol is clear and relevant for professionals. Patients should know that while the tool helps staff organize care more effectively, it is a management tool for clinics to improve their workflow.

What this means for you:
The study validates a new triage protocol to help dental staff better organize and categorize emergency cases.

Common questions

How does this triage system help patients?

The system helps dental staff organize their workflow by categorizing patients based on risk levels. During the study, 93.75% of patients reported pain, and the protocol helped identify those needing immediate attention. This allows for a more structured approach to care in busy emergency settings.

How quickly were patients seen during the study?

The study recorded an average time of 1 hour and 33 minutes between a patient's arrival and their treatment. The goal of the triage protocol is to ensure that the process remains clear and relevant for health professionals managing dental emergencies.

Is this new system reliable for medical staff?

Yes, the study showed a 97% agreement rate between different raters when using the protocol. This high level of reliability suggests that the tool is consistent and can be used by health professionals to categorize patients accurately.

This study aimed to develop and validate an Oral Health Reception and Risk Classification Protocol for dental emergencies to optimize care and organize service demands. This methodological study was conducted in four stages: literature review to identify existing models, protocol development, content validation by expert judges, and a pilot study to analyze reliability. The protocol, based on the Manchester Triage System and the Oral Health Network Guidelines of Paraná, was structured in nine items: personal data, history of the current condition, pain, pain classification, vital signs, need for medication, medical history, priority, and risk classification. The pilot study included 80 patients treated at the Dental Emergency Service of the School of Dentistry, Federal University of Uberlândia (PSO-HOUFU). A total of 93.75% of patients reported pain, predominantly spontaneous and intense. The most frequent classifications were yellow risk (50%) and green risk (45%). The average time between arrival and treatment was 1 h 33 min, with a dropout rate of 2.5%. Ten on-call professionals participated in the validation using the Content Validity Index. The Kappa coefficient indicated a 97% agreement. The protocol was considered valid in terms of appearance, clarity, and relevance. It can be safely used by health professionals in dental emergency triage.
