Diode Laser-Assisted Surgical Therapy for Early Treatment of Oral Mucocele in a Newborn Patient: Case Report and Procedures Checklist

The Effectiveness of Lasers in Treatment of Oral Mucocele in Pediatric Patients: A Systematic Review

The mucocele is the most common minor salivary gland associated disease of the oral cavity. It is also considered one of the most common biopsied oral lesions in pediatric patients. In recent years, extensive evidence has been published about the usage of lasers in treating mucoceles in pediatric patients. The aim of the present study was to assess the effectiveness of laser irradiation in the treatment of pediatric mucocele. An electronic search of databases (PubMed, Scopus, Web of Science and Google Scholar) was carried out in order to identify all relevant articles using a combination of the following keywords: "Pediatric", "Oral", "Mucocele", "Dental", "Oral Medicine", "Soft Dental Lasers", "Hard Dental Lasers", and "Lasers," for all case reports, case series, case-control and cohort studies published from 2007 to 2021. After limiting the search results, removing duplicate titles, and eligibility evaluation, 17 papers were enrolled in the study. Out of the total studies included, 10 articles were related to the diode (635 nm, 808 nm, 810 nm, and 980 nm), 5 to CO₂ (10,600 nm), 3 to Er, Cr: YSGG (2780 nm), and 1 involving KTP lasers (532 nm). All studies indicated successful clinical results on mucocele excision with better intra- and post-operative indicators. The general characteristics and outcomes were summarized, and the quality of the studies was assessed using CARE guidelines in this systematic review. The reduction or absence of pain and bleeding, hemostasis, reduced operating time, minimal analgesic consumption, and an antibacterial effect were among the advantages of laser irradiation in the included studies. The laser has proven itself to play an effective role in the treatment of oral mucocele in paediatric patients.

Combination of strontium chloride and photobiomodulation in the control of tooth sensitivity post-bleaching: A split-mouth randomized clinical trial

Objective

This split-mouth randomized controlled clinical trial assessed the effect of 10% strontium chloride in combination with photobiomodulation (PBM) for the control of tooth sensitivity (TS) post-bleaching.

Methods

The upper/lower, right and left quadrants of fifty volunteers were randomized and allocated to four groups (n = 25): PLACEBO—placebo gel + simulation of PBM; Placebo + PBM; STRONTIUM—10% strontium chloride + simulation of PBM; and PBM + STRONTIUM—10% strontium chloride + PBM. All groups received tooth bleaching treatment with 35% hydrogen peroxide. For the PBM treatment, the laser tip was positioned in the apical and cervical regions of the teeth bleached in the respective hemi-arch. The laser system was operated in continuous mode, using 1.7 J of energy. A dose of 60 J/cm² was applied to each point for 16 seconds under 808 nm near-infrared light (100mW of power), with a point area of 0.028 cm². TS was assessed during a 21-day follow-up, using the modified visual analogue scale.

Results

In the intragroup assessment, the Friedman test indicated that PBM + STRONTIUM promoted the greatest reduction in TS after the second week of treatment (p ≤ 0.05). The Wilcoxon-Mann-Whitney test indicated that the groups Placebo + PBM, STRONTIUM, and STRONTIUM + PBM did not differ statistically (p ≥ 0.05) in the first and third weeks of treatment The group PLACEBO exhibited the greatest TS in the first three days after each bleaching session.

Conclusion

The combination of 10% strontium chloride with PBM was effective in reducing post-bleaching TS; however, the combination of 10% strontium chloride with PBM was effective in reducing post-bleaching TS; however, it did not differ from the individual use of Placebo + PBM or STRONTIUM groups assessed after 21 days of follow-up.

Recurrent Oral Mucocele Management with Diode Laser

Background

Mucocele is the most common minor salivary glands disease. Its management may present a challenge for dental professionals. The aim of the present clinical case was to describe mucocele treatment with diode laser and its benefits. Case Report. A case of lower lip mucocele in a 10-year-old female patient is reported. A conventional excision surgery was performed. Two months later, the patient reported discomfort and swelling at the same operative site. The lesion had recurred. Thus, mucocele was removed using a diode laser with wavelength of 980 nm, an initiated fiberoptic tip of 300 μm, in continuous mode, and a power setting of 2 Watts. The procedure was rapidly completed with no bleeding. The patient was followed-up after 2 weeks and 6 months. The wound healed without complications: no postoperative discomfort or pain and no infection. There was no recurrence.

Conclusion

Diode laser is an effective, easy, bloodless, and well-accepted procedure to treat mucocele in pediatric patients.

Clinical, Histopathological, and Management Challenges of Multiple Familial Trichoepithelioma: A Case Report of a Patient Presenting with Multiple Facial Papules

Trichoepitheliomas (TE) are benign skin tumours of the pilosebaceous apocrine unit with follicular differentiation. Multiple familial trichoepithelioma (MFT) is a considerably rare condition inherited in an autosomal dominant pattern. We present a case of a 15-year-old male who presented with multiple papulo-nodular lesions in the central face and a family history of a similar type of lesions from his mother. Significance of consideration of various clinical differential diagnoses with serious pathological outcomes, strategies followed in the diagnosis including histopathological evaluation aided by immunohistochemical investigations, and subsequent challenges that may be faced in the management of MFT in light of the presentation with multiple facial papules are documented in this case report.

Massive Radicular Cyst in the Maxillary Sinus as a Result of Deciduous Molar Tooth Pulp Necrosis

The article describes a rare case of radicular cyst associated with deciduous right upper molars in a 5 y.o. male patient. The cyst developed asymptomatically in the maxillary sinus, thus causing considerable displacement of both premolar germs. Due to the severity of surgery, the patient was treated under general anesthesia in a one-day surgery system with use of the enucleation method. The extent of the lesion results in necessity of removal of the second premolar germ. Early diagnosis of the lesion would have resulted in a more conservative treatment plan. The purpose of this article is to lay emphasis on the pedodontist's role in early diagnosis of such lesions.

Alencar C, de Paula BLF, de A. Jassé FF, Araújo JLN, Silva CM. Photobiomodulation vs. Placebo on Post-Bleaching Sensitivity and Color Change: A Split-Mouth Clinical Study

Objective:

This study aimed to investigate the efficiency of Photobiomodulation (PBM) with low-level LASER therapy compared to placebo in post-bleaching sensitivity and color change during a three-week office bleaching treatment.

Methods:

A split-mouth model was used to evaluate 21 subjects. The right and left hemi-archs were randomized to one of two groups: GP (placebo): simulated LASER application followed by tooth bleaching with 35% hydrogen peroxide; and GL: treated with PBM followed by tooth bleaching with 35% hydrogen peroxide. A four-degree modified Visual Analog Scale (VAS) was used to assess tooth sensitivity after the application of an evaporative stimulus (stimulated pain). In addition, a daily questionnaire was used to measure unstimulated pain. The color change was measured using a spectrophotometer. The Friedman and Wilcoxon tests were used to analyze data sensitivity. Color results were statistically analyzed using Analysis Of Variance (ANOVA) followed by the Tukey post-hoc test.

Results:

There was no significant difference between GP and GL for stimulated pain evaluation (p> 0.05). However, there was a significant difference between the groups for unstimulated pain evaluation (p≤ 0.05). In addition, ΔE data did not reveal any significant difference in tooth color between groups at any time (p> 0.05).

Conclusion:

PBM prevented post-bleaching sensitivity compared to placebo, based on the daily pain assessment questionnaires. PBM did not compromise the quality of bleaching treatments.

Photobiomodulation and Pain Reduction in Patients Requiring Orthodontic Band Application: Randomized Clinical Trial

PURPOSE

The aim of this study was to investigate the effect of Photobiomodulation (PBM) in managing orthodontic pain intensity over time in patients requiring band application on upper first molars.

METHODS

Maxillary first molars were banded. In the trial group, each molar received single-session PBM on two buccal and two palatal points (λ = 830 ± 10 nm; 150 mW, 7.5 J/cm2; spot of 0.1 cm2; 5 sec per point), while the control group received a placebo treatment. All patients were asked to answer five pain rating scales to assess pain intensity at 5 minutes and 1, 12, 24, and 72 hours and completed a survey describing the type of pain and its temporal course in the next 7 days.

RESULTS

26 patients (mean age 11.8 years) were randomly assigned to a control or a trial group. The trial group showed significantly lower pain intensities (p < 0.05) at 5 min (M = 0.92, SD = 1.32), 1 h (M = 0.77, SD = 1.01), and 12 h (M = 0.77, SD = 1.54) after band application compared to the control group (5 min: M = 1.62, SD = 1.26; 1 h: M = 1.77, SD = 1.92; and 12 h: M = 1.77, SD = 2.17), whereas no difference between groups (p > 0.05) was found at 24 h (trial: M = 0.62, SD = 1.71; control: M = 1.08, SD = 1.75) and 72 h (trial: M = 0.31, SD = 0.75; control: M = 0.15, SD = 0.55). Patients in the control group reported more frequently the presence of "compressive pain" (58.8%, p < 0.05) from the appliance during the week after the application, while the trial group showed higher frequency of "no pain" (46.2%, p < 0.05). However, PBM did not affect the pain onset (trial: M = 10.86, SD = 26.97; control: M = 5.25, SD = 7.86), peak (trial: M = 15.86, SD = 26.29; control: 6.17, SD = 7.96), and end time (trial: 39.57, SD = 31.33; control: M = 22.02, SD = 25.42) reported by the two groups (p > 0.05).

CONCLUSIONS

PBM might be considered a promising alternative to decrease general pain intensity, although not affecting the typical pain cycle, in terms of the onset, peak, and ending times.

Healing without Surgery: A Case of Supernumerary Tooth,

Background:

Supernumerary teeth are present in 0,2-3% of the population. Multiple supernumeraries are often associated with syndromes such as cleidocranial dysplasia and Gardner's syndrome. They often hinder the permanent eruption’s teeth, causing cavities, periodontal lesions, pulp necrosis, and in some cases follicular cysts. Reactive lesions such as fibroma, local fibrous hyperplasia, pyogenic granuloma, and peripheral ossifying fibroma are frequent gingival lesions.

Materials and Methods:

We reported a case of a 9 years old patient with the missed eruption of a permanent element caused by a supernumerary tooth, associated with an exophytic palatine lesion. The deciduous incisor was still present and the supernumerary included. It was decided to proceed with the extraction of the deciduous and to wait for scheduling checks every two months. After a few months, the conoid shape supernumerary tooth erupted in the maxillary arch, so a fixed orthodontic therapy was performed to create the space for the central incisor’s eruption.

Results:

After a few months, the tooth began to erupt in the arch thanks to orthodontic traction. The patient was instructed to correct and specific oral hygiene maneuvers to lower the plaque index and try to reduce gingival hypertrophy.

Conclusion:

Supernumerary teeth often hinder the eruption and development of the related permanent tooth causing localized periodontal problems. Corrective fixed orthodontics requires more strict oral hygiene to avoid periodontal complications.
