Introduction Studies across the health service reveal benefits of teamwork and barriers to its optimal use. Drawing upon the established Maturity Matrix Dentistry method, the Skills Optimisation Self-Evaluation Toolkit (SOSET) was developed to enable the whole dental team to critically review how they address skill-mix in delivery of patient-centred oral healthcare in their practice. This paper outlines the development of the SOSET and explores its usefulness to general dental practice teams.

Methods Research literature and interview data from general dental practice teams were coded for high-level factors (positive and negative) influencing teamwork. We used this coding to identify skill-mix domains, and within each, define criteria. The SOSET process was refined following consultations with dental professionals and piloting.

Results Eighty-four papers were coded and 38 dental team members were interviewed across six sites. The SOSET matrix was developed containing nine domains reflecting the use of skill-mix, each containing six development-level criteria. The domains addressed factors such as team beliefs on skill-mix and knowledge of team members' scope of practice, patient demand, the business case, staffing and training, and the practice premises. The process was piloted in 11 practices across South Wales, and feedback was received from 92 staff members. Results showed that the SOSET process was straightforward, that the whole team could contribute to discussion and that it would be used to improve practice. Following piloting, four domains were merged into two new domains, and the number of criteria within all domains was reduced and the wording simplified (seven domains, with four criteria each).

Conclusion We used a systematic and rigorous process to develop the SOSET to support dental teams to progress their teamwork practices. Its usefulness was demonstrated in the pilot. The SOSET is now being offered to general dental practices across Wales.

简介整个卫生服务机构的研究表明了团队合作的好处和对其最佳使用的障碍。借助已建立的成熟度矩阵牙科方法，开发了技能优化自我评估工具包（SOSET），以使整个牙科团队能够严格审查他们在实践中如何解决以患者为中心的口腔保健的技能组合。本文概述了SOSET的发展，并探讨了其对一般牙科实践团队的用处。

方法对来自普通牙科实践团队的研究文献和访谈数据进行编码，以分析影响团队合作的高层因素（正面和负面）。我们使用此编码来识别技能组合领域，并在每个领域内定义标准。在与牙科专业人士协商并进行试点之后，SOSET流程得到了完善。

结果 编码了84篇论文，并在六个地点采访了38个牙科团队成员。SOSET矩阵的开发包含9个领域，反映了技能组合的使用，每个领域包含6个开发级别的标准。这些领域解决了诸如团队对技能组合的信念以及团队成员的实践范围，患者需求，业务案例，人员配备和培训以及实践前提等知识。该过程在南威尔士的11种实践中进行了试点，并收到了92名工作人员的反馈。结果表明，SOSET过程非常简单，整个团队可以为讨论做出贡献，并将其用于改进实践。试行后，四个域合并为两个新域，

结论我们使用了系统且严格的流程来开发SOSET，以支持牙科团队改进其团队合作实践。在试点中证明了其有用性。现在，SOSET已提供给整个威尔士的普通牙科诊所。
