The study demonstrated that the performance of specialized periodontal procedures was associated with the presence of BDSC that had bicarbonate jet prophylaxis devices. Previous studies have already shown that the use of ultrasonic instruments, compared to periodontal curettes, reduces treatment time and increases the number of patients treated13.
New instrumentation methods have been developed to achieve excellent clinical outcomes in a shorter time frame. Manual instrumentation typically requires more time in the office to achieve similar levels of effectiveness compared to ultrasonic instruments14. The use of the latter can significantly reduce the needed time, with reductions of up to 50%15. These results are consistent with other studies and indicate that, in comparison to manual instruments, ultrasonic instruments can statistically decrease treatment time by over 30%13.
Another variable with a positive impact on the completion of all specialized procedures by the BDSC was the proportion of periodontics specialists. When a dentist has specialization and works in their specific area, the workflow becomes more efficient and agile. This results in an increase in the number of appointments and a reduction in the waiting list. As a consequence, the service can achieve the goals set by the Ministry of Health16;17.
The research conducted by Galvão in 202118 revealed that the quality of secondary oral health care was positively influenced by the workload and the number of specialized professionals in each area. According to the authors, these factors explain the differences in the performance of municipalities regarding the provision of specialized dental services.
Regarding the achievement of goals, one of the significant factors in the present study was the presence of a manager dedicated exclusively to the area, along with additional training in Public Health/Public Management. A study conducted by Lucena and colleagues in 201919 found that in BDSCs where managers exclusively performed this role and had additional training in public management or public health, there was a notable increase in the execution of planning activities, resulting in a higher and more efficient number of appointments.
In this context, it becomes crucial for BDSCs to have managers, preferably dedicated solely to the administration of the service, who possess the necessary skills to carry out planning, self-assessment of the service, and rigorous monitoring of established goals. However, it is essential to emphasize that these activities and actions should not be seen merely as bureaucratic procedures devoid of meaning; they should involve managers and professionals who are directly involved in the provision of services and care19.
However, it is important to highlight that the situation in Brazil presents significant challenges in practice, especially in public healthcare institutions. The task of effectively training managers faces considerable obstacles, which resemble the challenges associated with the consolidation of the Brazilian Unified Health System (SUS, Sistema Único de Saúde) and the expansion of healthcare services20.
Regardless of the type of BDS (I, II, or III), they are needed to work a minimum of 40 hours per week, with the number of dental surgeons and assistants varying depending on the size of the service21. The decision regarding the weekly working hours of dental surgeons specializing in periodontology is the responsibility of the service manager, but it is expected that this choice aligns with the number of procedures necessary to achieve established goals. This is because the higher the professional's workload in this specialty, the greater the number of patient appointments they can accommodate.
The lack of compliance with the working hours of dental surgeons in public dental services significantly hinders the production capacity and utilization of the service by users. This becomes the main organizational barrier that directly impacts the achievement of service goals22.
It was observed that type III BDSCs showed superior performance in terms of the number of specialized procedures and were able to achieve the established goals in the field of periodontology. These results are in line with the research conducted by Da Silva and colleagues in 202123, where it was observed that services with more dental chairs and a more skilled team recorded a higher volume of appointments.
As a limitation of this study, it is important to emphasize that the use of secondary data from information systems may be subject to recording errors, which can lead to underestimation or overestimation of study estimates. Furthermore, the use of performance indicators that rely solely on goal fulfillment, without considering changes in population demands that influence the demand for dental services, is also a point to be considered. On the other hand, among the study's advantages, the evaluation of all existing BDSCs in Brazil stands out, as well as the use of the largest available database on procedures performed in specialized dental care, which currently represents the most comprehensive source of information on the subject in the country.
Future research should continue with the supervision and ongoing analysis of service indicators, prioritizing the investigation of the reasons behind their deficiencies. It is crucial to assess and propose measures to reverse this situation. Furthermore, it is imperative to evaluate the utilization of dental care, as the use of these services can highlight regional disparities in their availability and access.
