Wisdom teeth

BACKGROUND AND AIM: The surgical extraction of impacted wisdom teeth is a standard practice in dentistry. Unfortunately, inflammatory reactions such as discomfort, edema, and trismus frequently jeopardize patients' well-being after the extraction of third molars. Saline solutions at room temperature (25°C) are routinely used in impacted tooth extraction. Refrigerated saline solutions were used to work with cold solutions, and as the refrigerator temperature was 4°C, this study was designed to have a cold solution temperature of 4°C...

Third molar surgery is one of the most common surgical procedures performed in oral and maxillofacial surgery. Considering the patient's young age and the often-elective nature of the procedure, a comprehensive preoperative evaluation of the surgical site, relying heavily on preoperative imaging, is key to providing accurate diagnostic work-up, evidence-based clinical decision making, and, when appropriate, indication-specific surgical planning. Given the rapid developments of dental imaging in the field, the aim of this article is to provide a comprehensive, up-to-date clinical overview of various imaging techniques related to perioperative imaging in third molar surgery, ranging from panoramic radiography to emerging technologies, such as photon-counting computed tomography and magnetic resonance imaging...

BACKGROUND: Pericoronitis is a common pathological condition related to mandibular third molar teeth (wisdom teeth). It is an inflammation of the soft tissue surrounding the crown of an erupted or partially erupted tooth that causes pain and discomfort. We aimed to investigate the relation between third molar impaction types and pericoronitis. METHODS: This cross-sectional study assessed 60 patients referred to the Oral and Maxillofacial Surgery Department of Mashhad Dental School, Mashhad University of Medical Sciences, Mashhad, Iran in 2022 for totally and partially impacted mandibular third molar tooth surgery with pericoronitis...

Hemophilia A is a recessive congenital deficiency of factor VIII that is characterized by normal bleeding time, normal prothrombin time, and prolonged activated partial thromboplastin time. In moderate and severe cases, abnormal bleeding is observed even after minor trauma, and the diagnosis is usually made by the age of 5-6 years, whereas in mild cases, abnormal bleeding is detected after major trauma or surgery. Herein, we present a case of hemophilia A that was discovered due to difficulties with hemostasis after tooth extraction...

BACKGROUND: The aim of the present study is to determine the possibility of isolation and characterization of the human periodontal ligament stem cells (hPDLSCs) using limited harvested periodontal ligament (PDL) tissue of only one patient's wisdom teeth (2-4 teeth) under the more compatible terms of use in clinical application without using the fetal bovine serum (FBS). MATERIALS AND METHODS: In this pilot study, hPDLSCs were isolated from the impacted third molar, and tissue was scraped from the roots of the impacted third molar of 10 volunteers to enzymatically digest using collagenase...

The evaluation of third molar eruption in dental panoramic radiographs (DPRs) constitutes an evidence-based approach for forensic age assessment in living individuals. Existing methodologies involve staging morphological radiographic findings and comparing them to reference populations. Conversely, the existing literature presents an alternative method where the distance between third molars and the occlusal plane is measured on dental plaster models. The aim of this study was to adapt this measurement principle for DPRs and to determine correlation between eruption and chronological age...

BACKGROUND: Few studies have compared the effects of piezosurgery and conventional rotary surgery for impacted wisdom teeth on the quality of life. Among these studies, the inclusion parameters and evaluation methods have varied. MATERIAL AND METHODS: This study aimed to compare the effects of piezosurgery and conventional rotary instruments on the quality of life using a standardised method. Patients with bilateral and symmetric mandibular impacted wisdom teeth were included based on the Winter and Pell-Gregory scale and Yuasa difficulty index criteria...

OBJECTIVE: This study aimed to analyze the crown and root morphology of maxillary and mandibular third molars, and assess their position in relation to adjacent anatomical structures using clinical examination and radiographic images. MATERIALS AND METHODS: A total of 176 extracted impacted or partially impacted third molars were included in this study. Orthopantomogram images (OPG) were used to evaluate the number of roots, position, depth of impaction relative to the occlusal plane of the second molar, and angulation of maxillary and mandibular third molars...

This study aimed to compare preoperative data relevant to third molar surgery based on radiographic orthopantomography (OPG) and orthopantomogram-like MR images (MR-OPG), using five different MR protocols. X-ray-based OPG and OPG-like MRI reconstructions from DESS, SPACE-STIR, SPACE-SPAIR, T1-VIBE-Dixon, and UTE sequences were acquired in 11 patients undergoing third molar surgery, using a 15-channel mandibular coil. Qualitative (image quality, susceptibility to artifacts, positional relationship, contact/non-contact of the inferior alveolar nerve (IAN), relationship to maxillary sinus, IAN continuity, root morphology) and quantitative (tooth length, retromolar distance, distance to the IAN, and distance to the mandible margin) parameters of the maxillary and mandibular third molars were assessed regarding inter-reader agreement and quantitative discrepancies by three calibrated readers...

OBJECTIVE: The aim of this study was to determine the prevalence of mandibular third molar malposition and its impact in relation to the lower second molar using panoramic radiography. METHODS AND MATERIALS: This was a cross-sectional descriptive study of 353 panoramic images of patients who visited the Dental Clinic of the International University of Rabat. Panoramic images were analyzed in order to determine the number of second molar pathologies associated with the positions of third molars...

BACKGROUND: Peripheral facial palsy is characterized by acute peripheral facial nerve paralysis. While most cases have no identifiable cause, some are linked to infectious or non-infectious factors. The potential connection between herpes simplex virus-1 (HSV-1) and peripheral facial palsy has been studied since the 1970s, with a small number of cases reported following tooth extraction. Patients who have treatment delayed for over a year and still exhibit no signs of recovery have a bleak prognosis...

OBJECTIVES: To assess the scientific evidence related to the role of the mandibular third molars on the late crowding of the lower anterior teeth in patients with or without previous orthodontic treatment. The secondary outcomes included changes in mandibular arch width and arch length. MATERIALS AND METHODS: The databases PubMed, Scopus, ProQuest, and Google Scholar were searched from inception until April 2022. The included papers were studies evaluating the role of mandibular third molars on crowding of mandibular anterior teeth in patients of any age and gender, with mandibular third molars impacted or semi-impacted or erupted...

The aim of this study was to determine the content of mercury in impacted third molars from Legnica-Głogów Copper Area residents to emphasize the effects of environmental pollution on the human body. A group of 72 patients with an average age of 27.3 ± 6.9 years participated in the study. Within this study, the research group (Legnica-Głogów Copper Area residents) comprised 51 individuals, while the control group (residents of Wrocław) consisted of 21 participants.

Double teeth, like fusions and geminations, are rare disorders of tooth development. In this short case presentation, we describe the unique appearance of a fully erupted mandibular wisdom tooth in a 72-year-old patient whose tooth exhibited gemination. This was possible because tooth 46 had to be removed from the patient at the age of 20 and the missing molar was not replaced. This geminated tooth of 48 had been in function for almost 50 years and finally had to be removed due to a periodontal inflammation...

Thyroid gland dysfunctions can adversely affect patients' systemic health and well-being. Thyroid disease is the most common endocrine disorder. Recognizing early signs and symptoms of hypothyroidism is crucial in the early diagnosis of hypothyroidism. Oral health care providers must obtain comprehensive medical records from patients with hypothyroidism before dental treatments.

BACKGROUND: The dermatoglyphics have been used in several researches for predicting various pathologies of oral cavity like periodontitis, dental caries, impacted teeth, mal-occlusion, developmental defects such as cleft lip and palate, and potentially malignant disorders. Impacted teeth may be associated with various pathologies such as caries, pericoronitis, dentigerous cysts, and keratocystic odontogenic tumors; therefore, predicting impacted teeth through dermatoglyphic patterns can help in diagnosis and future treatment planning of such event...

Tooth autotransplantation is an effective treatment to replace missing teeth. Digital planning can facilitate successful autotransplantation. Guiding templates are highly recommended when performing cases in healed ridges in the posterior area to reduce excessive bone subtraction and increase the chances of fitting of the donor tooth in the new socket. This case report highlights the use of three-dimensional planning tools and fully-guided drilling templates for successful tooth autotransplantation in the posterior area...

METHODOLOGY: Retrospective data were analyzed using panoramic radiographs of 1,500 subjects were correlated with demographic details age and gender...

BACKGROUND: Facial swelling, pain, and trismus are the most common postoperative sequelae after mandibular third molar (M3M) surgery. Corticosteroids are the most used drugs to reduce the severity of inflammatory symptoms after M3M surgery. This study aimed to evaluate the effect of a single pre-operative dose of prednisone on pain, trismus, and swelling after M3M surgery. METHODS: This study was designed as a split-mouth randomized, controlled, triple-blind trial with two treatment groups, prednisone (PG) and control (CG)...

Oroantral communication is an unnatural communication of the maxillary sinus with the oral cavity, often resulting from dental extractions, infection, trauma, or excision of cysts or tumors. Pathological epithelialization of oroantral communication leads to oroantral fistula. Various techniques have been proposed for surgical closure. Uneventful healing of the defect can be achieved in the absence of antral infection. Hence, medical management of maxillary sinusitis should precede surgical closure of the defect...
