唇部粘液腺囊肿手术体会

口唇部粘液腺囊肿临床多见 ,属口腔科常见病 ,确诊容易 ,应手术治疗。一般唇粘液腺囊肿为潴留性囊肿 ,无上皮衬里。手术必须切除与其相关的粘液腺体组织 ,避免复发。术中如果切破囊壁 ,易造成残留[1] 。若再次手术 ,因有瘢痕形成 ,手术层次不清 ,增加患者负担与痛苦 ,对术者也有困难 ,应避免。在这里谈谈有关手术体会。手术切口设计 ,根据囊肿大小定。需注意大囊肿梭形切口宽度要小于囊肿 ,太宽术后造成畸形。术前可用龙胆紫表出设计的切口线。手术 :用圆刀切开粘膜层 ,尤其大囊肿采用小切口时 ,这一刀就很关键 ,没有切开粘膜层或直接切破囊…

Clinical comparison between the bleaching efficacy of light‐emitting diode and diode laser with sodium perborate

The aim of this clinical study was to test the efficacy of a light‐emitting diode (LED) light and a diode laser, when bleaching with sodium perborate. Thirty volunteers were selected to participate in the study. The patients were randomly divided into two groups. The initial colour of each tooth to be bleached was quantified with a spectrophotometer. In group A, sodium perborate and distilled water were mixed and placed into the pulp chamber, and the LED light was source applied. In group B, the same mixture was used, and the 810 nm diode laser was applied. The final colour of each tooth was quantified with the same spectrophotometer. Initial and final spectrophotometer values were recorded. Mann–Whitney U‐test and Wicoxon tests were used to test differences between both groups. Both devices successfully whitened the teeth. No statistical difference was found between the efficacy of the LED light and the diode laser.

Effects of low-level laser therapy on the rate of orthodontic tooth movement

OBJECTIVES: To test the hypothesis that mechanical forces combined with low-level laser therapy stimulate the rate of orthodontic tooth movement. STUDY DESIGN: This study was a double blind, randomized placebo/control matched pairs clinical trial to test the efficacy of GaAlAs low-level laser therapy (LLLT) on 12 young adult patients who required retraction of maxillary canines into first premolar extraction spaces using tension coil springs with fixed edgewise appliance. LLLT was applied on the mucosa buccally, distally and palatally to the canine on the test side and using a pseudo-application on the placebo side. Dental impressions and casts were made at the commencement of the trial and at the end of the first, second and third months after starting the trial. Measurement of tooth movements was made on each stage model using a stereo microscope. RESULTS: There was no significant difference of means of the canine distal movement between the LLLT side and the placebo side for any time periods (p-value = 0.77). CONCLUSION: The energy density of LLLT (GaAlAs) at the surface level in this study (25 J/cm(2)) was probably too low to express either stimulatory effect or inhibitory effect on the rate of orthodontic tooth movement.     

Activation of ethylenediaminetetraacetic acid by a 940 nm diode laser for enhanced removal of smear layer

Laser enhancement of ethylenediaminetetraacetic acid with cetrimide (EDTAC) has previously been shown to increase removal of smear layer, for middle‐infrared erbium lasers. This study evaluated the efficiency of EDTAC activation using a near‐infrared‐pulsed 940 nm laser delivered by plain fibre tips into 15% EDTAC or 3% hydrogen peroxide. Root canals in 4 groups of 10 single roots were prepared using rotary files, with controls for the presence and absence of smear layer. After laser treatment (80 mJ pulse^?1, 50 Hz, 6 cycles of 10 s), roots were split and the apical, middle and coronal thirds of the canal were examined using scanning electron microscopy, with the area of dentine tubules determined by a validated quantitative image analysis method. Lasing EDTAC considerably improved smear layer removal, while lasing into peroxide gave minimal smear layer removal. The laser protocol used was more effective for smear layer removal than the ‘gold standard’ protocol using EDTAC with sodium hypochlorite (NaOCl). In addition, lasers may also provide a benefit through photothermal disinfection. Further research is needed to optimise irrigant activation protocols using near‐infrared diode lasers of other wavelengths.     

Successful hair removal on intraoral grafts using the diode laser: Report of two cases

Aim: The aim of this study was to describe the successful epilation of intraoral grafts using the diode laser system. Methods and Results: Two male patients at a 12‐month follow‐up – who underwent radical resection of oral cancer located in the mouth floor and tongue followed by reconstruction with cutaneous flap – showed hypertrichosis in the graft region, leading to dysphagia and dysphonia. The diode (980 nm) laser was performed for both cases in order to remove the ectopic hair. Excellent aesthetic and functional outcomes with total hair removal and alteration of the tissue surface were achieved. Conclusions: There is no currently standard protocol for the laser epilation use on hairy grafts because each graft required a different number of sessions for total epilation. The diode laser system appears to be a successful therapeutic option for patients suffering from hypertrichrosis in the oral cavity.     

Low level laser therapy for dentinal tooth hypersensitivity

A comparative double blind study testing low level laser therapy (Gallium/Aluminium/Arsenide laser [GaAIAs]) against placebo was carried out in the management of dentinal tooth hypersensitivity. Subjects demonstrating dentinal hypersensitivity and complying with strict selection criteria were randomly assigned to an active and placebo group. Low level laser therapy was applied for one minute to both the apex and cervical area of the tooth; and reapplied at one week, two-week and eight-week intervals. Dentinal hypersensitivity was rated at each visit.
There were 28 subjects in the placebo group and 22 and 21 subjects, respectively, in the tactile sensitivity and thermal sensitivity groups. Comparisons between the groups were conducted using independent groups t -test. In both the tactile and thermal sensitivity groups differences between the active and placebo groups were significant from the first week and increased further in the second and eighth weeks. The mean value of thermal sensitivity decreased 67 per cent (p < 0.001) compared with placebo (17 per cent) and tactile sensitivity decreased 65 per cent (p = .002) compared with placebo (21 per cent) at eight weeks.
Results demonstrate that the GaAIAs laser is an effective method for the treatment of both thermal and tactile dentinal hypersensitivity. There were no reported adverse reactions or instances of oral irritation.     

Preliminary experience with promethazine hydrochloride injection in the sclerotherapy of oral mucocele

Mucoceles are common in the minor salivary and sublingual glands. Sclerotherapy is a possible treatment strategy for mucoceles. The purpose of this study was to evaluate the clinical outcomes of sclerotherapy with promethazine hydrochloride injection in treating mucoceles. Thirty-seven patients were enrolled. Sclerotherapy was performed with promethazine hydrochloride injection (25 mg/ml) through the mucosa. Patients were followed up at 1, 3, and 6 months after the last sclerotherapy. Clinical data were reviewed. The lesions (range 2–30 mm in diameter) occurred on the ventral tongue tip (20 patients), lower lip (11 patients), and floor of the mouth (six patients). The amount of sclerosant per injection ranged from 0.2 ml to 1 ml. At the 6-month follow-up, 33 patients showed resolution with no recurrence. One patient showed a significant response with a 5-mm-diameter nodule remaining after two sclerotherapies. Three patients who underwent two or more sclerotherapies failed to show an improvement. The overall cure rate was 91.9% (96.8% for mucoceles of the minor salivary gland, 66.7% for ranulas). Complications were rare and mild. Sclerotherapy with promethazine hydrochloride injection for the treatment of mucoceles is safe. It is effective for mucoceles of the minor salivary glands, but its application for ranulas requires further investigation.
