RESUMO
BACKGROUND: Maxillofacial deformities are skeletal discrepancies that cause occlusal, functional, and esthetic problems, and are managed by multi-disciplinary treatment, including careful orthodontic, surgical, and periodontal evaluations. However, thin periodontal phenotype is often overlooked although it affects the therapeutic outcome. Gingival augmentation and periodontal accelerated osteogenic orthodontics (PAOO) can effectively modify the periodontal phenotype and improve treatment outcome. We describe the multi-disciplinary approaches used to manage a case of skeletal Class III malocclusion and facial asymmetry, with thin periodontal phenotype limiting the correction of deformity. CASE SUMMARY: A patient with facial asymmetry and weakness in chewing had been treated with orthodontic camouflage, but the treatment outcome was not satisfactory. After examination, gingiva augmentation and PAOO were performed to increase the volume of both the gingiva and the alveolar bone to allow further tooth movement. After orthodontic decompensation, double-jaw surgery was performed to reposition the maxilla-mandibular complex. Finally, implant placement and chin molding were performed to restore the dentition and to improve the skeletal profile. The appearance and function were significantly improved, and the periodontal tissue remained healthy and stable. CONCLUSION: In patients with dentofacial deformities and a thin periodontal phenotype, multi-disciplinary treatment that includes PAOO could be effective, and could improve both the quality and safety of orthodontic-orthognathic therapy.
RESUMO
BACKGROUND: Patients with severe periodontitis often require multidisciplinary treatment to achieve healthy periodontal tissue, normal occlusion, and optimal aesthetics. In the present study, we aimed to evaluate the efficacy of multidisciplinary non-surgical treatment in a patient with stage IV/ grade C periodontitis, malocclusion, and dentition defects. CASE SUMMARY: A 47-year-old woman visited our periodontology department due to teeth mobility problems and difficulties chewing food. The patient had no history of drug allergies or systemic disease. Initial therapy involved scaling and root planning with a Gracey scaler and periodontal ultrasonic therapeutic apparatus using a periodontal endoscope (Perioscopy, Zest Dental Solutions, United States) to control the periodontal inflammation prior to treatment. Five months later, orthodontic treatment was then performed to treat occlusion and overall aesthetics. After completion, a Maryland bridge was used to restore Nos. 22, 31, and 41 teeth. Florida probing (Florida probe, United States) was performed every 2-3 mo to evaluate the periodontal condition throughout treatment. Overall, multidisciplinary non-surgical treatment resulted in satisfactory aesthetic results with healthy periodontal tissue and stable occlusion. CONCLUSION: In some patients with stage IV/grade C periodontitis, systematic and sequential non-surgical treatment can provide excellent therapeutic results.
RESUMO
BACKGROUND: We report three patients with drug-induced gingiva overgrowth (DIGO) caused by nifedipine, a calcium channel blocker, who were treated and followed up for 1-3 years. We discussed their symptoms, treatment process, treatment prognosis, and follow-up results. CASE SUMMARY: All the patients had a history of nifedipine treatment to control hypertension. Besides nifedipine, Patient 1 was prescribed immunosuppressant cyclosporine A to control nephritis, which is also implicated in GO. Thus, we assumed that a synergistic effect between the drugs contributed to the severity of Patient 1's condition. This condition has been reported to be more pronounced in patients with periodontitis. In the course of treatment, Patients 1 and 2 did not stop or change drugs. After initial periodontal treatment, periodontal surgery, and later periodontal support and better plaque control, their gingival hyperplasia was well managed and controlled. Under the guidance of a physician, Patient 3 replaced her calcium-channel blocker drug with losartan potassium and hydrochlorothiazide tablets. She received initial treatment without surgery, obtaining a good curative effect. CONCLUSION: Patients' compliance, self-plaque control, and professional periodontal therapy have a vital role in treating and preventing the recurrence of DIGO.
RESUMO
OBJECTIVE: To evaluate the efficacy of scaling and root planing (SRP) with a periodontal endoscope in the treatment of residual pockets in patients with periodontitis after initial periodontal therapy. METHODS: Patients with residual pockets [probing depth (PD)≥5 mm] were included and randomly assigned to the endoscope group (SRP with a periodontal endoscope) or SRP group (SRP alone). The PD, attachment loss (AL), and bleeding on probing (BOP) of residual pockets were recorded before treatment and at 3 and 6 months after treatment. Data were analyzed with SPSS 20.0 software. RESULTS: Compared with the baseline values, the percentage of PD≥5 mm sites, PD, AL, and BOP (+)% in the endoscope group and SRP group at 3 and 6 months after treatment decreased (P<0.05). Compared with the values at 3 months after treatment, the percentage of PD≥5 mm sites, PD, AL, and BOP (+)% at 3 and 6 months after treatment decreased in the endoscope group (P<0.05), whereas no statistical difference in these values was observed in the SRP group (P>0.05). Compared with those in the SRP group, the percentage of PD≥5 mm sites and PD at 3 and 6 months after treatment and AL and BOP (+)% at 6 months after treatment in the endoscope group decreased (P<0.05). CONCLUSIONS: SRP with a periodontal endoscope shows a better effect in improving the PD, AL, and BOP of residual pockets (PD≥5 mm) in patients with periodontitis after initial periodontal therapy and has advantages in improving the long-term curative effect of this therapy.
