RESUMO
Introduction: The aim of this study was to evaluate soft-tissue changes in Egyptian cleft lip/palate (CLP) patients after conservative non-surgical maxillary advancement using face mask therapy. Methods: This prospective cohort study included 20 Egyptian patients with unilateral CLP, six females and 14 males, ranging in age from 10 to 15 years and suffering from moderate maxillary deficiency. These patients had been chosen randomly from the Oro-dental Genetics Clinic at the National Research Centre, Egypt. For lateral cephalometry tracing and superimposition of pre-operative and post-treatment data, this study used Dolphin 11.0 software. Subnasal (Sn), pronasal (Pn), soft tissue pogonion (Pg), labial superior (Ls), stomion superioris (Ss), labiale inferior (Li), stomion inferioris (Si) and soft tissue Menton (Me) were the soft tissue points used in this analysis. Results: All of the cases were successful and demonstrated a positive response to the orthodontic traction. All post-operative linear measurements of the measured soft-tissue points showed statistically significant advancement (P = 0.05) except for pronasal linear measurements, which did not show a significant difference post-treatment (P = 0.84). Discussion: With the use of the face mask procedure, both upper and lower lip soft-tissue points improved significantly, but nasal points remained unchanged, requiring more management.
RESUMO
INTRODUCTION: Gummy smile (GS) is a nonesthetic condition that affects the confidence of many young people. The present study aimed to compare the results of two approaches used in the management of GS in a group of Egyptian females. MATERIALS AND METHODS: This comparative cohort study included 24 female patients aged 25-35 years, divided into two groups. Group A included patients treated with diode dental laser gingivectomy, while Group B included patients who were treated with Botox injection. The clinical assessment of the pre-and post-operative measurements of exposed gums in millimetres on an active full smile was analyzed and compared for both groups. The paired t-test was used to compare pre and post measurements in each group, and the mean difference between the groups was compared using the independent t-test. RESULTS: Group A showed instant improvement, while Group B results appeared 1 week later. The variation between preoperative and postoperative GS measurements in both groups was statistically significant. The preoperative and postoperative mean ± standard deviation was (5.17 ± 0.9 and 1.89 ± 0.5) in Group A and (4.27 ± 1.0 and 1.79 ± 1.0) in Group B. Comparison between the two groups revealed a highly significant greater mean difference of 3.27 ± 0.5 mm in Group A than Group B (P < 0.001). The findings were satisfactory in all cases of both approaches, and there were no complications. DISCUSSION: Using a diode laser to treat gummy smiles for oro-dental genetics case with gingival hypertrophy saves time and effort compared to conventional surgical techniques. Diode dental laser is a safe fast and effective method of treatment giving more superior results than Botox injection which showed a less invasive alternative temporary GS therapy that is easily guaranteed and more patient-favored.
