Abstract
Background and Aim: Ossifying fibroma (OF) is a benign fibro-osseous lesion, which is usually diagnosed between the ages of 20 and 40 years. The female to male ratio is 5:1, with affinity for posterior mandibular region. The aim of the present report is to discuss a case of OF and its clinical, radiological and pathological characteristics and the related surgical approach.
Case presentation: A left mandibular impacted premolar with an associated lesion was incidentally found on a radiograph of a 27-year-old woman. The patient did not report any clinical symptoms. Inferior alveolar nerve involvement by the lesion was obvious in radiographic study. The tooth was extracted and the associated lesion was enucleated under general anesthesia through step-by-step surgery and after releasing the inferior alveolar nerve.
Conclusion: Surgical treatment of Ossifying fibroma consists of enucleation and curettage in small and well-defined lesions, while larger lesions are usually resected. Prognosis is good with a low recurrence rate even with enucleation and after long-term follow-up.

Abstract
Background and Aim: Research on reducing the symptoms and discomfort after periodontal surgery is a priority. This study aimed to evaluate the effect of cyanoacrylate adhesive on tissue healing after periodontal surgery.
Materials and Methods: In this split-mouth clinical trial, all patients who needed periodontal pocket removal surgery in two or more sextants were examined after receiving written informed consent. The mouth of each patient was randomly divided into control and case groups. Cyanoacrylate adhesive was used in the case group, and sutures were used in the control group to close the wound. Pain, plaque index of the surgical site, and tissue healing were evaluated in the first week of follow-up. The probing depth in the surgical site was assessed at the second follow-up (6 weeks after surgery). All the parameters were statistically analyzed by Mann-U-Whitney test.
Results: In the first week of follow-up, the level of pain was 4.7±1.34 in the control group and 4.4±1.68 in the case group with no statistically significant difference (P=0.2). The healing rate was 3.3±0.53 in the control group and 2.7±0.64 in the case group with no statistically significant difference (P=0.3). The plaque index in the first week of follow-up was 3.9±0.82 in the control group and 3.8±0.97 in the case group (P=0.2). The probing depth in the sixth week of follow-up was 2.5±0.67 in the control group and 2.8±0.6 in the case group (P=0.2).
Conclusion: Considering the results, it seems that cyanoacrylate adhesive can be a good alternative to sutures, especially when the patient cannot present for suture removal at the appointed time.

Abstract
Background and Aim: Computer-aided design/computer-aided manufacturing (CAD/CAM) has been widely used in implant dentistry. Recent computer-guided dynamic navigation systems promise an accurate approach to minimally invasive implant placement. Robot-assisted surgery has been used in dentistry since 2017. The present study aims to review the properties, clinical outcomes, advantages, and limitations of navigation, robotics, and CAD/CAM in implant placement surgery.
Materials and Methods: An electronic search of the literature was conducted mainly through PubMed, ScienceDirect, Cochrane Library, and Google Scholar databases. Studies in the English language were considered for inclusion if they evaluated robotics, CAD/CAM, and navigation in implant placement. Finally, 21 articles were selected.
Results: Guided implant surgery is assumed accurate, precise, and reliable; it also has a lower complication rate compared to freehanded implant surgery. Surgical guides could be indicated for patients with limited mouth opening, tight interdental spaces, a strong gag reflex, and distal implants. Several studies have reported that computer-assisted surgery improves the accuracy of implant placement. Expensive equipment, high costs, and gaps between the guides and drill bite are the disadvantages of digital implant placement.
Conclusion: Computer-aided implant navigation systems can improve implant placement outcomes. Digital procedures have shown accurate outcomes in implant surgery. Despite the advantages of guided surgery, deviation of implant position from the planned position still occurs. However, improvements in digital dentistry are slowly overcoming these challenges.

Abstract
Oral cancer is a major public health problem worldwide and is among the ten most common cancers. Despite the advances in research and treatment, oral cancer is still one of the major challenges in medical science. Common treatments for this cancer include surgery, radiotherapy, and chemotherapy, as well as adjuvant photodynamic therapy (PDT). The aim of this study was to evaluate oral cancer and its treatment methods with an emphasis on the use of adjuvant PDT. The present study is a review performed by searching the articles published in the past 20 years (2000-2020) in Elsevier, PubMed, Springer, and Wiley databases with “oral cancer”, “photodynamic therapy”, and “treatment modalities” keywords. Research shows that PDT can be an effective way to treat oral cancer due to its few side effects and minimal invasion. However, accurate evaluation of the efficacy of PDT requires further studies.

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to provide better results compared with conventional treatments, a significant variation exists in the applied laser parameters such as different wavelengths and energy densities of laser. The objective of this study was to collect preliminary information about the type and parameters of surgical lasers and how to use them technically based on the available literature on this topic.
Materials and Methods: After initial screening of 152 potentially relevant articles identified through an electronic search, 44 articles were selected based on the eligibility criteria by three independent reviewers. The inclusion criteria included studies on the outcomes of periodontal high intensity laser therapy in humans published in English between 2013 and 2021 in journals indexed in PubMed Central, Science Direct, Wiley Online Library, Springer or Google Scholar.
Results: The results showed that diode, Nd:YAG, Er:YAG, Er;Cr:YAG and CO2 lasers had the highest efficacy for frenectomy, gingivectomy, and osteotomy with specific wavelength, power density, frequency, and pulse mode. Various lasers have been suggested for the abovementioned purposes, and the method of choice depends on the efficacy and availability of laser.
Conclusion: This study confirmed higher efficacy of different laser types compared with conventional treatments.

Background and Aim: Considering the side effects of high doses of opioids taken postoperatively for pain control, paracetamol and magnesium sulfate may be able to aid in pain control. This study assessed the effects of paracetamol and magnesium sulfate on the level of pain and opioid intake following orthognathic surgery.
Materials and Methods: In this double-blind randomized clinical trial, patients scheduled for bimaxillary orthognathic surgery were randomly assigned to two groups of 25. Group 1 patients received 1 g infusion of intravenous acetaminophen (paracetamol) administered within 20 minutes while group 2 patients received 50 mg/kg magnesium sulfate infusion one hour prior to completion of surgery. The patients were asked to express their level of pain prior to discharge from the recovery, and every 4 hours for 12 hours using a visual analog scale (VAS). Patients with pain score > 5 at any time received 30 mg pethidine. The total received dosage of pethidine postoperatively was recorded and those that received pethidine were not included in pain score analysis. Data were analyzed by generalized estimating equation (GEE), and Mann-Whitney U, Chi-square, and t-tests.
Results: The pain score was not significantly different between the two groups at the time of recovery and 4 and 8 hours (P>0.05). The magnesium sulfate group had significantly lower pain score at 12 hours (P=0.009). The difference in pethidine dosage was not significant (P>0.05).
Conclusion: Both magnesium sulfate and paracetamol decreased postoperative pain and the need for opioid consumption, but magnesium sulfate was slightly more effective.
