Hypothesis
This systematic review aims to analyze existing classification systems for rotated teeth and assess their clinical applicability.
Conclusion
There is no adequate classification system to assess the rotation of anterior teeth and mandibular teeth, and existing systems for posterior teeth need to be standardized.
Supporting Evidence
- The skeletal Class II and Class III groups exhibited similar average positions of the first molar.
- Upper molar rotation was primarily observed in dental Class II patients, with a higher mesial rotation angle of 78.6°.
- The incisors demonstrated the highest degree of rotation (7.4°–20.2°), while the molars displayed the lowest degree of rotation (0.8°–7.4°).
- Eight out of the 10 studies assessed the rotation of various teeth and provided quantitative outcomes.
Takeaway
This study looked at how teeth can be rotated and found that we need better ways to measure and classify these rotations to help with dental treatments.
Methodology
A systematic review was conducted by searching six databases for studies on tooth rotation, including both qualitative and quantitative outcomes.
Potential Biases
Nine studies were rated as moderate quality, indicating reasonable methodological soundness but with limitations.
Limitations
Only English language studies were included, and a meta-analysis could not be performed due to the diversity of techniques and outcomes.
Participant Demographics
Participants included patients with various malocclusions across all age groups.
