The aim of this study was to evaluate the prevalence of bifid mandibular canal (BMC) using cone-beam computed tomography (CBCT) and panoramic images through meta-analysis.

Databases of Scopus, PubMed, and Web of Science were searched to find the relevant studies. Studies the met the inclusion criteria were selected. Variables of prevalence, side, length and diameter of BMC and sex were assessed. Data was analyzed using STATA software version 17.

Of the 1164 articles initially selected, 36 were enrolled. A total of 38077 patients were considered. The overall prevalence of BMC was 18.0%. Studies that evaluated CBCT images reported higher prevalence of BMC compared to panoramic images (25.0% vs 3.0%). The prevalence of BMC was higher in men than women and slightly higher in right side than the left side of the jaw, but none of those differences were significant.

The results have shown a total prevalence of 18.0% for BMC. Detection power of CBCT images were higher than panoramics. There was no significant relation between prevalence of BMC with sex or side of the jaw.

Lasers in oral surgery have been extensively studied in recent years. Laser treatment is now a well-known technology that is frequently employed on oral soft tissues. The carbon dioxide (CO2) laser was one of the first soft tissue removal lasers. Because of the strong affinity of the CO2 laser to water, it is best used for removing, vaporizing, and coagulating these tissues. In minor oral surgery, CO2 laser therapy has shown advantages. Therefore, this study examined the CO2 laser use in minor oral soft tissue surgery.

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards were followed in this study. A question for research encompassing the inclusion criteria for the participants, intervention, comparison, outcome, and study design (PICOS) was formulated. The search queries were entered into the PubMed/Medline, Scopus, and Embase databases. Consideration was given to publications published between January 1, 2018 and March 15, 2023.

The research included 37 studies after narrowing search results, eliminating duplicate titles, and conducting an eligibility review (three animal studies, seven case reports, three case series, and twenty-four clinical studies). CO2 lasers alone or in combination with other therapies successfully treated oral potentially malignant disorders (OPMDs), oral tumors, oral fibrous-epithelial lesions, gingival melanin hyperpigmentation, pyogenic granuloma, socket preservation, mucocele, high labial frenulum attachment, and so on. CO2 lasers reduced intra- and postoperative complications and adverse effects, improved postoperative functional results, ablated tissues with precision, and minimized disease recurrence and malignant transformation.

Our study found that the CO2 laser in oral minor surgeries is successful, but further randomized clinical trials and multicenter studies are recommended to compare CO2 laser surgery to other treatments.

This study aimed to compare the analgesic effects of Ibuprofen and Bromelain after periodontal surgery.

A double-blinded crossover clinical trial was conducted on 22 patients needing two crown lengthening surgeries without bone surgery or with limited bone surgery on two quadrants of the maxilla, with control and test sides. Each quadrant was randomly assigned to Bromelain (500 GUD) or Ibuprofen (400 mg). Immediately after the surgery and 6 hours after it, the first dose of the drugs was packaged in the same capsules in A and B. Postoperative pain was evaluated during the first 8 hours and on the following day using a visual analog scale (VAS).

Using the VAS, the Ibuprofen group showed significantly lower mean pain scores than the Bromelain group at 4 hours (P=0.047). In contrast, there were no significant differences between the two groups at 2, 6, 8, 10, 12, 24, and 48 hours (P>0.05).

The effectiveness of Bromelain for pain control following periodontal surgery was comparable to that of Ibuprofen. Therefore, Bromelain can be an efficient replacement for Ibuprofen in managing pain after periodontal surgery, especially in patients with gastric ulceration and increased bleeding tendency.

Ranula is a limited mucus retention on the floor of mouth. Due to the young age of patients, over the years, attempts were made to find minimally invasive and effective surgical techniques. To date, however, there is still no gold standard. The modified micro-marsupialization is an effective and minimally invasive technique, with minimal risk of relapse, although there are very few reports about it. 

Case Report:

A 12-year-old male presented to our ENT Clinic with a rounded swelling with regular and defined margins, measuring 4x3 cm, soft and painless, non-compressible and bluish. Clinical diagnosis of ranula was made and a modified micro-marsupialization was performed: eight interrupted sutures using silk 3-0 were placed perpendicularly to the major axis of the lesion, from one side of the lesion to the other, without reaching the underlying tissue. No sutures were lost during follow-up, no complications occurred. Complete healing was reached after removing sutures on the 30th postoperative day. At 6 months control no relapse was observed.

Modified micro-marsupialization is strongly indicated and recommended, especially in pediatric patient, due to its low invasiveness and its very low relapse rate. The poor case history found in the literature is probably an indication of the lack of knowledge of modified micro-marsupialization which, in our opinion, could be considered the gold standard.

Bichectomy consists of the partial removal of the Bichat ball (BB) of its buccal extension and smoothing the facial contour. The objective of this study is to present, by means of a clinical case, bichectomy surgery with the use of a high-power diode laser and cold scalpel on different sides of the same patient, analyzing the trans-surgical phase and the pain and edema like consequence operative of each technique and 6-month follow-up.

A 20-year-old female patient reported the occurrence of involuntary trauma to the cheek mucosa and rounded facial appearance. After anamnesis and clinical examination, bichectomy was proposed. For comparison, on the right side, an incision was made using a laser, while on the left side, with a cold scalpel. To assess and measure the progression of treatment, photographs and facial measurements were repeated before the procedure, 7, 14, and 28 days after the procedure, and 2, 3, and 6 months after the procedure.

The high-power diode laser showed excellent applicability for bichectomy due to its hemostatic properties in the trans-surgical phase. In addition, it promoted greater patient comfort, with less edema and pain on the side of the face where it was used.

Blue and blue-violet diode lasers (450 and 405 nm) seem to represent an interesting approach for several clinical treatments today. The aim of this narrative review is to describe and comment on the literature regarding the utilization of blue and blue-violet lasers in dentistry.

A search for “blue laser AND dentistry” was conducted using the PubMed database, and all the papers referring to this topic, ranging from 1990 to April 2020, were analyzed in the review. All the original in vivo and in vitro studies using 450 nm or 405 nm lasers were included in this study. All the articles on the LED light, laser wavelengths other than 405 and 450 nm and using lasers in specialties other than dentistry, as well as case reports, guideline papers and reviews were excluded.

From a total of 519 results, 47 articles met the inclusion criteria and were divided into 8 groups based on their fields of application: disinfection (10), photobiomodulation (PBM) (4), bleaching (1), resin curing (20), surgery (7), periodontics (1), endodontics (1) and orthodontics (3).

Blue and blue-violet diode lasers may represent new and effective devices to be used in a large number of applications in dentistry, even if further studies will be necessary to fully clarify the potentialities of these laser wavelengths

The novel coronavirus disease (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus, is rapidly expanding. Due to the rapid spread of this disease through respiratory droplets, oral and maxillofacial surgery can be correlated with a high risk of Covid 19 transmission.

A comprehensive review of the literature has been done for this purpose. Interventions were prioritized based on their necessity and urgency for the well-being of the patients.

Although Elective surgery must be delayed until COVID-19 pandemic situation has been insolvent, urgent surgery can be done in negative pressure operative room on the patients with Covid 19 and with the adequate personal equipment protection in healthy patients.

Triage and prioritize of procedures in oral and maxillofacial surgery during Covid 19 pandemic is of great importance.

 An alternative to interrupted sutures for implant surgery at sites of edentulous ridges is the continuous locking suture, however it tends to loosen and time-consuming as the result.

The modified continuous double locking suture is a modification of continuous locking suture, which is designed to approximate flap margins of an edentulous area.

 Application of modified continuous double locking suture, reduces the chance of suture loosening by adding an extra knot at each area.

 By utilizing modified continuous double locking suture, it is easier to manipulate flap margins; nonetheless, more studies are needed to evaluate its efficacy in dental practice.

Preoperative anxiety is the subject of major concern for many patients.

The current study aimed at determining the effect of anesthesia consultation on decreasing anxiety in patients undergoing oral and maxillofacial surgery.

This randomized clinical trial was conducted on 250 patients undergoing different maxillofacial surgeries. The data collection instruments included a questionnaire containing the Spielberger state-trait anxiety inventory (STAI) and a researcher-made questionnaire with queries on the demographic characteristics and surgery-related information. Analysis of the data was performed in SPSS, using descriptive and inferential statistics.

The findings showed that the majority of patients (38.4%) had moderate anxiety; there was no significant difference between the consultation and control groups in terms of age and gender. Also, the scores of state and trait anxiety were significantly lower in the consultation group, compared with the control group.

The present results showed that preoperative anesthetic consultation reduced preoperative anxiety, compared with the control group. Our findings suggest that anesthetic counselling services should be provided for individuals experiencing high levels of stress.

 Photobiomodulation (PBM) has been considered a popular technique for reducing the post-operative complications after periodontal surgeries. The aim of this case series study was to evaluate the PBM effect on accelerating wound healing after crown lengthening procedure.

 Four patients were referred to a private office for crown lengthening surgery. After completion of medical history and oral examination, the surgery for patients were done. Then, PBM was done by diode laser at 980 nm, in continuous mode with output power of 0.3 w for 20 sec.

 On follow up session after 2 weeks, satisfactory results of PBM were detected in all patients.

 The application of 980 nm diode laser for PBM after oral soft tissue surgeries can be beneficial due to accelerating wound healing.

Third molars  are the last teeth to grow and require more attention in the oral cavity because they can leave pathological effects. Considering the controversy clinical decisions about asymptomatic third molars, dentists' lack of attention to over third molars developed during therapeutic recommendations for patients, and limited evidence about the effects of asymptomatic third molars on adjacent teeth, the purpose of this study was an assessment of the effect of asymptomatic erupted third molar on periodontal status and a distal caries of the adjacent second molar.

In this cross-sectional study, the distal caries of second molars as examined using panoramic radiography, clinical examination and periodontal parameters including plaque index, gingival index, bleeding on probing, periodontal pocket depth and clinical attachment loss in 134 jaw quadrants patients. The patients were divided into two groups of asymptomatic erupted third molars and without erupted third molars. The independent samples t-test was used to compare periodontal parameters between the two groups while chi-square test was used to compare the frequency of caries.

In periodontal parameters evaluation in mandible, periodontal pocket depth and clinical attachment loss in third molar group were higher than in without third molar group, whereas in maxilla all periodontal parameters in third molar group were higher than without third molar group. In the caries evaluation, both maxillary and mandibular distal caries of the second molar were significantly higher in the third molar group than in the without third molar group.

Erupted third molars increase the risk of periodontal disease and distal caries in the adjacent second molars, and dentists should be particularly attentive to the third molars in examination sessions.
