“…The exposure of dentin cores through the loss of the enamel cover can also be clearly delimited. The loss of one‐third of the crown length sometimes appears less clear, however, studies 14,16,17 have shown that the evaluation of tooth wear is reproducible at this level of differentiation. The original 5‐point ordinal scale had been developed in Amsterdam as early as in 2001 16 .…”

“…The original 5‐point ordinal scale had been developed in Amsterdam as early as in 2001 16 . Reproducibility has also been demonstrated for the 8‐point ordinal scale, which includes further subdivisions of Grades 1 and 3 12,17 . It is helpful that this evaluation is reproducible not only clinically (intra‐orally), but also if intra‐oral photographs and/or dental casts are used instead 17 .…”

“…In order to determine the Tooth Wear Status, one grade is recorded for each tooth surface (occlusal/incisal, vestibular and oral). The individual values are entered in a graphical diagnostic form (Table 2) based on the above‐mentioned five‐point ordinal scales 14,16 ; optionally, the 8‐point occlusal/incisal ordinal scale can be used 12,17 . In contrast to the Tooth Wear Screening, where the highest grade per sextant determines the overall evaluation, in the Tooth Wear Status, the highest grade per tooth is relevant for this determination.…”

Background: Tooth wear is a multifactorial condition, leading to the loss of dental hard tissues. Physiological tooth wear is a slow process that normally does not lead to any subjective symptoms. When the condition progresses, it can become pathological, and several signs and symptoms may occur. The Tooth Wear Evaluation System (TWES) was described to implement a systematic diagnostic and management approach. Recently, management guidelines were presented in a European Consensus Statement (ECS) as well.Objectives: To evaluate the TWES in practice and to integrate the principles described in the ECS in order to compose a renewed TWES 2.0 and a new taxonomy. Methods:The TWES and the recommendations of the ECS were used by dental clinicians, in order to test its applicability in practice.Results: Agreement was reached that the TWES 2.0 will use a stepwise approach, with a straightforward Tooth Wear Screening part and a more detailed Tooth Wear Status part. Also, the assessment of pathology from the ECS is incorporated in the TWES 2.0 (both classification and taxonomy). Conclusions:In the TWES 2.0 is described that tooth wear is pathological if moderate/severe/extreme tooth wear is present, in combination with one or several described signs and symptoms. Aetiology can be assessed by findings that indicate a chemical and/or a mechanical cause. The taxonomy may help to identify situations in which preventive (restorative) interventions in early stages of tooth wear can be indicated. The reliability and validity of the adapted parts must be proven.

“…Consequently, when time progresses, these surfaces become more difficult to restore. 11 In the future, intra-oral scans can be used to measure objectively the amount of loss of the dental hard tissues. 4,10 The dental team has two treatment options available, namely counselling/monitoring and a restorative treatment.…”

“…Monitoring can be done by quantifying the amount of tooth wear with an evaluation system, intra-orally, on casts and/or on intra-oral photographs. 11 In the future, intra-oral scans can be used to measure objectively the amount of loss of the dental hard tissues. The main goal of counselling and monitoring is to avoid further loss of hard dental tissues as much as possible, as well as measure and determine tooth material loss over time.…”

Objectives Tooth wear is a multifactorial condition leading to the loss of dental hard tissues. A counselling/monitoring protocol is of importance in order to keep that loss as limited as possible. Since many factors are involved and a time span of decades is included, research to disentangle all these processes in patients is difficult. Instead, a modelling technique was used that is able to deal with time, costs and probabilistic and stochastic information. The aim was to shed light on the question: does a yearly or a once‐in‐five‐years counselling/monitoring protocol yield better outcome measures? Methods A so‐called timed automata model was adopted, analysed with the tool UPPAAL. To our knowledge, this is the first time that formal modelling is applied in dentistry. In this article, a UPPAAL model for the evaluation of tooth wear is described. Results Using the UPPAAL model, it was calculated that with a yearly counselling/monitoring protocol the severity of tooth wear at age 74, the total costs per person and the number of restorative treatments were less, and the number of so‐called “good years” was higher. Conclusions With the use of the UPPAAL model, it may be concluded that a yearly counselling/monitoring protocol can yield better outcome measures. Clinical Significance Regarding dentistry in general and tooth wear in particular, with the use of a timed automata model in UPPAAL, actual research questions can be answered, factors of influence in a multifactorial condition like tooth wear can be clarified, and future research topics can be determined.
