Scientists have developed solutions, for oral health by leveraging advancements in medicine. These solutions, known as “ reconstructive dentistry “ aim to address the limitations and short lifespan of restorative methods. Unlike restorative treatments, reconstructive dentistry focuses on not only restoring the structure of tissues but also their physiological functions. To achieve this, it requires an effort among dentists, biologists, stem cell researchers, material scientists, tissue engineers and other experts. Consequently, this study was carried out to create and evaluate a fellowship program called “Reconstructive Medicine in Dentistry.” The program aims to foster an approach towards reconstruction, in dentistry.

This research involved three stages. Utilized a mixed method approach. In the first stage, we developed a design based on the Kern model, which involved conducting a review of relevant studies to extract and determine the goals and topics related to medical reconstruction, in dentistry. Expert panel meetings were held to finalize these goals and topics. For each target group, we identified the learners, learning environment and educational strategies. We also made arrangements for implementing the program. Established evaluation methods for both students and the program itself. Subsequently, we implemented the designed curriculum for two groups of students. Finally, we evaluated the program’s effectiveness through questionnaires and semi structured interviews, with students, professors and organizers. The collected data was analyzed using statistics.

In 2020 and 2021, two groups of students were meticulously selected from disciplines such as maxillofacial surgeons, oral medicine specialists, periodontists, endodontists, and more, after passing the entrance exam. The primary objective of this program is to educate graduates with the skills to restore missing tissues in the mouth, jaw and facial regions using cutting edge regenerative medicine techniques. The curriculum was developed in collaboration with experts from areas like tissue engineering, dental specialization (including maxillofacial surgeons) biomaterials and developmental biology. Both students and professors expressed satisfaction, with the program.

A group of professors, from specialties came together to implement a fellowship program in reconstructive dentistry. The main goal of this program was to train specialists in tissue reconstruction for patients who have suffered jaw and facial injuries; by using advanced methods in medicine. Additionally, this initiative can also be a step towards strengthening the university’s movement towards third and fourth-generation universities. The findings from this study can provide insights, for those involved in planning and implementing interdisciplinary fellowship programs.

Osteoblastoma (OSB) is an uncommon (3% of benign and 1% of all) primary bone neoplasm with extremely rare occurrence in head and neck, especially the maxillary bone region. OSB of the jaw mainly involves the mandible bone. We report a 10‑month‑old male who was admitted to the hospital because of a mass in the right maxillary jaw region. Clinicoradiopathologic features of the patient have been described. The histological examinations revealed OSB of the maxillary bone. Total surgical resection of the tumor was performed with 10 months of follow‑up and there is no evidence of recurrence. To the best of our knowledge, it is the first report of maxillary OSB in an infant.

Ameloblastoma is one of the most common types of oral odontogenic tumors. As per literature, ameloblastoma mostly occurs in the mandible butthe maxillary ameloblastoma has a more aggressive behavior due to anatomical features. Also, unicystic ameloblastoma may have lower recurrent rate. In this case report, we present a 60-year-old male patient with a history of unicystic ameloblastoma, which the intraluminal adenomatoid odontogenic tumor excisional biopsy surgery was performed but the patient didn’t follow the treatment completely, and after two years he came back with swelling of the right upper alveolar ridge. After the second surgery, the histopathologic report revealed a mixed plexiform-follicular ameloblastoma recurrence and it seemedthat previous surgery was not sufficient and more radical treatment is needed for the lesion.

Desmoplastic fibroma (DF) is a rare benign but aggressive fibrous lesion with an unknown etiology. It has an affinity for the mandible. DF has a high rate of recurrence after surgical resection. In this study, we report the therapeutic management of a recurrence of DF in the lower jaw in a 2‑year‑old boy. He responded well to second surgical intervention with wide resection and immediate reconstruction with plate. The purpose of this case report is to emphasize the particularity of the case, treatment modalities, and differential diagnosis in DF.

Subcutaneous emphysema of the face is an uncommon complication caused by dental procedures such as curettage, root canal treatment, extraction, restorative treatment and dental instruments like air-water syringe and hand piece. Subcutaneous emphysema can be life threatening if involved the spaces of neck and superior mediastinum. In this rare case, subcutaneous emphysema of the face was developed after potential removal of an amalgam tattoo with the help of an excavator. The patient was completely recovered after three days of timely medical treatment.

Cementoblastomas are rare benign odontogenic tumors. Diagnosis of these lesions must be made by an association of clinical, radiographic, and histopathological findings. Cementoblastomas rarely occur in both primary and permanent dentitions. We describe the sixth case of cementoblastoma in the literature with the involvement of both deciduous and permanent teeth. The aim of this case report is to present the clinicoradiopathologic features of a cementoblastoma in a 4.5-year-old boy with an unusual recurrence. The first clinical and radiographic features appeared on the deciduous mandibular second molar. The second lesion occurred 1 year after treatment at 5.5 years old, involving the permanent mandibular first molar, and a subsequent lesion was seen at age 8 years in the edentulous region of the extracted mandibular first molar. After the last surgery, there was no recurrence of the lesion at 6 months’ follow-up. Follow-ups of patients with cementoblastomas are highly recommended for an early detection of recurrences

Surgical removal of inferior third molar tooth is associated with post operative complications such as pain, trismus and edema. Decreasing the post-operative inflammation and edema is one of the important goals in drug administration. For management of post operative pain, nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids can be administered. C-reactive protein (CRP) is one of the best paraclinical parameters for evaluation of tissue inflammation.
Thirty one patients aged 18 to 31years old were enrolled and evaluated in this randomized controlled clinical trial. They were classified into two groups, randomly. In one group, NSAID and in the other group tramadol was administered orally, after dental surgery. Blood samples were taken before procedure and 72 hours after procedure for CRP level evaluation.
Regardless of the type of drugs, CRP changes were statistically significant in both groups before and after operation. Elevation of CRP serum level was higher in tramadol group in comparison to Ibuprofen group and the difference was statistically significant. (P.value 0.05).
This study has shown that NSAIDs have more anti-inflammatory effect than opioids.

Our study was designed to assess the effect of the submucosal injection of dexamethasone on postoperative discomfort after surgical removal of impacted mandibular third molars.
Twenty six patients with bilaterally bony impacted mandibular third molars were recruited to this split mouth study. On the study side, prior to surgery, 8 mg of dexamethasone was injected in buccal vestibule submucosally, while the control side received no steroid. Complications such as swelling, trismus and infection were evaluated postoperatively.
The results showed that the patients experienced significantly less swelling (p= 0.001) on study side on the 3rd and 7th postoperative days compared to the control side. The amount of trismus was significantly less (p= 0.001) after submucosal injection of dexamethasone on both time intervals.
Perioperative submucosal injection of dexamethasone can significantly reduce postoperative swelling and trismus after surgical removal of the impacted teeth.

Surgical removal of third molar is one of the most common surgical procedures in oral surgery and is often associated with complications such as pain, swelling and trismus. The main purpose of the study was to assess the therapeutic effect of low level laser (LLL) irradiation on postoperative edema and wound healing compared to routine postoperative management after third molar surgery. A double blinded, randomized, controlled clinical trial was conducted in 2 groups of 20 patients, each undergoing surgical removal of their impacted mandibular third molars. Postoperatively, patients in study group were irradiated with Ga-Al-As laser with a diode wavelength of 890nm and a power output of 80 mw in pulsed mode for 6 minutes intraorally. The control group received only routine post-surgical management including 400 mg Ibuprofen 4 times daily and cold packs. Intraoral low level laser therapy (LLLT) resulted in a statistically significant reduction in the amount of swelling on the 2nd postoperative day compared to the control group. The healing process was significantly better in laser- irradiated wounds. The LLLT with Ga-Al-As laser seems to be safe and can be considered as an effective modality for reducing postoperative discomfort and promoting wound healing after third molar surgery.

Introducation: The long-term outcome and clinical results of gaparthroplasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared. The purpose of this study was to compare the effect of gap arthroplasty and costochondral graft methods on reankylosis, a mount of mouth opening and growth. A non-randomized, retrospective clinical study of l0 cases (5-12 years old) of condylar ankylosis of the mandible, surgically treated during a 10 year period from 2002 to 2012 was performed. Four patients were treated by condylectomy and interpositional flap, whereas six were treated by condylectomy and immediate costachondral rib grafts. The first group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, and computed tomography (CT) were used post surgically to evaluate rib graft, condylar growth and function, occlusion, facial, and condylar symmetry. Data were analyzed by SPSS 16 statistical software using Mann-Whitney, Paired T-test and Chi-square tests. Children with long-standing condylar ankylosis of the mandible treated by condylectomy and interpositional flap showed more favorably when activators were used post-surgically. Gaparthroplasty with functional activator post-operatively can be considering for TMJ ankylosis.

The long-term outcome and clinical results of gaparthro plasty used for the treatment of condylar ankylosis of the mandible in children with application of postoperative activator appliances and costochondral rib graft are evaluated and compared.

A nonrandomized, retrospective clinical study of 10 cases of condylar ankylosis (18 Joints) of the mandible surgically treated during a 12 year period from 1990 to 2002 was performed. Four patients were treated by condylectomy and interpositional Flap and Six patients were treated by condylectomy and Immediate costachondral rib grafts. The First group underwent long-term postoperative therapy using removable activator appliances. Casts, radiographs, photographs, computed tomography (CT) Scans, were Used post surgically to evaluate rib graft, condylar growth and function, occlusion, and Facial and condylar symmetry.

Symmetry, arch coordination, correction of occlusal canting, mandibular deviation, facial growth , and prevention of reandkylosis were obtained and better controlled in those cases that cnderwent long-tern orthodontic activator therapy post operatively and were followed closely.

Children with long-standing condylar ankylosis of the mandible and its resultant facial asymmetry and occlusal canting (Secondry to a non functional joint and Maxillary compensation) treated with condylectomy and interpositional flap treated more favorably when activators were used postsurgically. The patients that failed to comply with or continue activator therapy postsurgically developed complications relating to mandibular deviation , occlusal dysharmony, asymmetry and rankylosis of the temporo mandibular joint (TMJ).
