BACKGROUND: Cervical enamel projections (CEPs), particularly grade III lesions, are recognized as local anatomical factors in the progression of furcation involvement by impeding effective plaque control and promoting periodontal tissue destruction. Conventional removal methods often require invasive flap surgery. This retrospective study evaluated the short-term clinical outcomes of a minimally invasive technique combining endoscopic visualization with ultrasonic instrumentation for the removal of CEPs in molars with furcation involvement.
METHODS: Clinical records of patients who underwent endoscope-guided ultrasonic removal of grade III CEPs between 2024 and 2025 were retrospectively reviewed. All consecutive eligible cases were screened to minimize selection bias. Periodontal parameters, including probing depth (PD), clinical attachment loss (CAL), bleeding on probing (BOP), and tooth mobility were collected at baseline, 6 weeks and 6 months after therapy.
RESULTS: A total of 68 patients (147 molars) were included. Statistically significant short-term improvements in periodontal parameters were observed. The median PD decreased from 6 mm (interquartile range [IQR]: 4–7) to 3 mm (IQR: 2–3) at the 6-month follow-up (P < 0.001) and CAL values also improved over time. The proportion of BOP (+) sites declined from 82.99% to 30.61%. The procedure was performed safely, allowing clear visualization and removal of CEPs under endoscopic guidance. Patient-reported satisfaction was high, and no significant adverse events were reported.
CONCLUSION: Within the limitations of this retrospective study and short-term follow-up, endoscope-guided ultrasonic removal of CEPs was associated with improvements in early periodontal clinical parameters. These changes likely reflect clinical attachment gain related to soft tissue adaptation rather than periodontal regeneration. The preliminary findings suggest that endoscopic visualization may facilitate precise anatomical correction in furcation areas. Further well-designed prospective studies are required to confirm these findings.
