Background: lip lengthening procedure is one of the surgical options for the correction of gummy smile in patients with short upper lip. Methods: A comparative clinical study was conducted on 15 patients requiring lip lengthening procedure for the esthetic correction of excessive gingival exposure with gummy smile. Scalpel was used in seven patients and diode laser in the remaining eight patients. Under infiltration anesthesia, about one cm strip of mucosa was excised at the vestibular depth and the mucosa of the lip was sutured to the alveolar mucosa. Results: The diode laser group demonstrated less postoperative pain and swelling. Regarding postoperative ecchymosis, three patients in the scalpel group developed ecchymosis and no cases were noted in the laser group, the difference was statistically significant. No patient in the laser group developed wound dehiscence and only one patient in the scalpel group had wound dehiscence at third postoperative day. Observed at one month postoperatively, the laser treated groups had less obvious scar than the scalpel group. Conclusion: Diode laser is a valuable tool in performing lip lengthening for gummy smile.

Background. The present study aimed to assess the effect of botulinum toxin type A (BTX-A) for the management of gummy smile and evaluate its stability after administrating BTX-A clinically and using electromyography. Methods. The investigators designed and implemented a prospective clinical study on 10 patients with a gummy smile. Patients with different types of gummy smile were injected with BTX-A in the levator muscles of the upper lip and were followed for six months. The effect of BTX-A was evaluated clinically and using electromyography preoperatively and after two weeks and three and six months. Statistical analyses were carried out using repeated measures ANOVA and post hoc Bonferroni tests for pairwise comparisons. Results. The sample consisted of 10 patients with an anterior gummy smile (n=3), posterior gummy smile (n=2), mixed gummy smile (n=3), and asymmetrical gummy smile (n=2). There were significant differences (P<0.001) between the mean gingival display and compound muscle action potential at two-weeks and three-month follow-ups. The maximum result was obtained at the two-week interval. The mean gingival display and C-MAP values increased slightly at the three-month postoperative interval and gradually increased to the baseline values at six-month follow-up. Conclusion. BTX-A is an effective, minimally invasive, and temporary treatment modality for gummy smiles. The electromyographic study is a convenient method for assessing changes in the upper lip muscle contractility to quantify the effect of BTX-A in the treatment of gummy smile.

The Difference

Background: This was a prospective, randomized, double blind, comparative, clinical study to assess the efficacy of Esmolol and Labetalol, in low doses, for attenuation of sympathomimetic response to laryngoscopy and intubation. Materials and Methods: This study was conducted on 50 ASA 1 patients of either sex undergoing elective surgeries under general anaesthesia. Patients were randomized into two groups; group E who received intravenous Esmolol (0.5 mg/kg) or group L who received intravenous Labetalol (0.25 mg /kg) prior to induction and hemodynamic parameters were recorded as per designed protocol to assess stress response to laryngoscopy and intubation. Results: Both the study groups had similar demographic profile. Instat version 3.10 was used for statistical calculations. The study data were analyzed using statistical methods of mean, standard deviation. Esmolol (0.5 mg/kg), abetalol (0.25 mg/kg) significantly attenuated the rise in heart rate, systolic blood pressure, and RPP during laryngoscopy and intubation. However, the difference was not statistically significant among the values for DBP and MAP. Conclusion: From our clinical study it can be concluded that in lower doses, intravenous Labetal ol (0.25 mg/kg) is a better agent than intravenous Esmolol (0.5 mg/kg) in attenuating the sympathomimetic response to laryngoscopy and intubation. Usual dose of esmolol used to obtund intubation response is 2-4mg/kg, while labetalol has been tried in all doses ranging from 0.25, 0.5, 0.75, and 1 mg/kg.

Introduction: This study evaluated the effectiveness of an 810-nm diode laser as an adjunct to scaling and root planning (SRP) in improving periodontal parameters in patients with chronic periodontitis. Methods: This randomized clinical trial consisted of 36 patients (16 females and 20 males) with chronic periodontitis and pocket depths of 4-6 mm. The quadrants were randomly divided into two sides; one side of each patient was selected as the laser group (SRP + laser) and the other side served as the control group (SRP alone). An 810-nm diode laser was applied in the laser side to remove the outer gingival epithelium (1.5 W, CW) as well as the inner epithelium of the periodontal pockets (1 W, CW). The clinical parameters including bleeding on probing (BOP), probing depth (PD), plaque index (PI), and clinical attachment level (CAL) were measured at baseline and 6 and 18 weeks after therapy. Results: In both groups, there was a significant improvement in BOP, PD, PI and CAL over the course of the experiment (P<0.001). Significantly lower BOP was found in the SRP + laser group than the SRP alone group after 6 and 18 weeks of intervention (P<0.05). The difference in other parameters was not significant between the two groups, neither at 6 nor at 18 weeks after the treatment (P>0.05). Conclusion: Within the limitations of this study, the association of the diode laser with standard non-surgical periodontal therapy (SRP) provided minimal additional benefits for patients with moderate chronic periodontitis.

BACKGROUND Gingival melanin pigmentation (GMP) is a common aesthetic concern. The gold standard for depigmentation, is surgery. Recently soft tissue lasers have gained popularity. The purpose of this study was to compare and evaluate the clinical efficacy of surgical blade and laser treatment in terms of pain perception and wound healing outcomes, 7 and 14 days following the procedures for the treatment of gingival depigmentation. METHODS This 14 day follow up comparative clinical study, utilized a split mouth design, in the anterior region. Fifteen patients with moderate to heavy bilateral gingival pigmentation were included as per the criteria by Dummett et al. The patients’ right side (group 1) was treated with surgical blade and the left side (group 2) with diode laser (Picasso, AMD LASERS™) by a trained clinician. Pain perception was assessed using Visual Analog Scale (VAS) and wound healing was assessed using clinical parameters. RESULTS Data was analysed using paired t test and Wilcoxon’s signed rank test. P value of < 0.05 was considered statistically significant. On day 7, more than 70 % patients had slight pain in group 1. Whereas, 47 % experienced no pain in group 2. The mean difference in VAS scores between the groups at day 7, was statistically significant. No statistically significant distinction in wound healing was observed 7 days following both procedures. No pain, and complete epithelialisation was noted in both groups on day 14. CONCLUSIONS Pain experienced by the patients was slightly more in the scalpel group compared to laser. There was no difference in wound healing between both groups. KEY WORDS GMP, Gingival Melanin Pigmentation, VAS Scale, Depigmentation, Wound Healing, Laser, Surgical Blade, Split Mouth Design

Gummy Smile

Objective: This study aimed to compare the changes in the gummy smile in cases treated with botulinum toxin (BTX) application or orthognathic surgery. Methods: The retrospective sample comprised 61 subjects with gummy smile divided into 2 groups according to treatment received for gummy smile correction: 1-38 patients (6 male; 32 female), at a mean age of 28.60 years (s.d.=6.09), treated with BTX application; 2- 23 patients (7 males and 16 females) at a mean age of 29.59 years (s.d.=5.72) treated with orthognathic surgery. Patients from the BTX group refused to undergo orthognathic surgery. The measurement of the gingival exposure was performed in extraoral photographs of the posed smile, before and after treatment, and it was defined as the difference between the stomion of the upper lip and the incisal edge of the maxillary central incisor minus the height of maxillary central incisor obtained in the patient's dental casts. The data were obtained before (T1) and after treatment (T2) and change of gingival exposure with treatment (T2-T1). Intergroup comparison of gummy smile was performed with independent t-tests. Results: The surgical group presented significantly greater correction of the gummy smile with treatment than the BTX group. Conclusion: Gummy smile presented a greater improvement in patients treated with orthognathic surgery than with botulinum toxin application.
