Hypothesis
The study aims to evaluate the positional changes of periodontal tissues, particularly the biological width, following surgical crown-lengthening in human subjects.
Conclusion
The biological width was reestablished to its original vertical dimension at all sites after 6 months.
Supporting Evidence
- Significant apical displacement of the free gingival margin was observed at treated sites.
- The biological width was reestablished to its original vertical dimension at all sites after 6 months.
- Statistically significant changes were noted in probing depth and attachment level at treated sites.
Takeaway
Doctors did surgery to make teeth longer, and after 6 months, the space around the teeth was back to normal.
Methodology
A clinical trial study involving 15 patients was conducted over 6 months, measuring various periodontal parameters at baseline, 1, 3, and 6 months.
Limitations
The study only included patients from one dental college and may not be generalizable to all populations.
Participant Demographics
Patients aged 15 to 72 years requiring surgical crown-lengthening.
