“…Failure to achieve this may lead to irrevers-ible tooth morbidity and unnecessary tooth mortality. Iatrogenic tooth damage is a common finding in some aspects of restorative dental interventions 4,5,6 . Therefore, concerns over patient safety have led to a decrease in the popularity of the practice whereby students practice new skills on patient 2,7 .…”

Abstract:Background: Though the use of simulators in operative dentistry is not new, the teaching and learning practices that take place during clinical sessions in skills laboratories are rarely reported. This study was designed to determine the current practices relating to teaching and learning of dental clinical skills in southern Nigeria. Methods: A cross-sectional study was conducted among the final year dental students in southern Nigeria using anonymous structured questionnaire as instrument for data collection. The questionnaire items included statements relating to existing teaching and learning practices. A five-point Likert scale response option was provided and descriptive summary statistics was computed. Results: There were 56 (34.8%) females and 105 (65.2%) males. Most of the students (41.0%) agreed that the theoretical concept behind clinical skills is taught prior to clinical sessions and most agreed that the objectives of each clinical session are stated and that the procedures are usually demonstrated. Most of the respondents (39.8%) agreed that feedback was sometimes embarrassing and given at the end of clinical sessions (76.6%). Equipment breakdown was a major challenge to learning. Conclusion: Dental education in the skills labs within the region appeared standard. However, feedback should be continuous and constructive. Equipment breakdown was the major constraint to learning.

“…1,4 However, Medeiros et al reported a lower frequency of damage (49-60%) and attributed this to elimination of small defects over time. 5 Iatrogenic damage to the enamel surface is most often in the form of vertical grooves up to 1 mm wide, and also appears as fine scratches, indentations and extensive damage (a combination of defects over a large surface area). 4,5 Such injuries can potentially increase the risk of dental caries developing on the affected surface by altering its properties.…”

“…1,2,4,6,10 Furthermore, there is a concern that enamel damage on approximal surfaces will appear as interproximal radiolucencies which could be misdiagnosed as carious cavitations, resulting in unnecessary restorative treatment of non-carious surfaces. 2,5 Despite their suitability, metal matrix bands are rarely used to prevent iatrogenic damage during Class II preparations. 1,5,11 The same is true for traditional tooth separators.…”

Background: This study examined the effect of operator experience, dominance, tooth position and access, on frequency and extent of iatrogenic damage to approximal tooth surfaces during conventional Class II cavity preparations. The effectiveness of protective devices in minimizing damage was also explored. Methods: 10 students and 10 experienced dentists each prepared 24 Class II cavity preparations in typodont teeth without protection; 10 utilizing stainless steel matrix bands and 10 utilizing protective wedges. The frequency and extent of damage were analysed with respect to the above variables. Subsequently, 20 natural and 20 typodont teeth were utilized to establish the relationship in depth of damage caused by a high-speed diamond bur on typodont versus natural teeth. Results: Dentists caused iatrogenic damage on 74% of approximal surfaces without protection, which fell to 50% and 46% respectively when matrix bands and wedges were used as guards. The corresponding rates of damage for students were 94%, 80% and 44%. There was no difference in depth of damage caused on the two types of teeth when bur was in contact with teeth for a very short time. Conclusions: Greater operator experience and the use of guards reduces iatrogenic damage to proximal surfaces during preparation with high-speed rotary instruments.
