Trauma to the adjacent hard and soft tissue is the most common iatrogenic injury during extraction of the mandibular third molar. As every functional component of the dental arch is of prime importance in contemporary dental practice, the major concern must be in conserving the tooth and its structure as much as possible. The present case discusses the application of this conservative approach for management of iatrogenically damaged distal root of the mandibular second molar during extraction of impacted third molar, in which excessive guttering of alveolar bone and fractured apical third of distal root of 37 was observed radiographically...

OBJECTIVE: The objective of the study was to determine the potential risk of tooth/root displacement into the soft tissue during the third molar surgery. While performing third molar surgeries, one of the many complications is displacement of the tooth into the soft tissues. This can be due perforation of the lingual cortical bone during surgery or the position of the tooth root which may be close to the lingual bone. MATERIALS AND METHODS: Retrospective samples of 251 patients were collected who had undergone cone-beam computed tomography (CBCT) for various reasons...

Cerebrospinal fluid (CSF) contains several molecules which are essential for neurogenesis. Human dental pulp stem cells (hDPSCs) are putatively neural crest cell-derived that can differentiate into neurons and glial cells under appropriate neurotrophic factors. The aim of this study was to induce differentiation of hDPSCs into neuroglial phenotypes using retinoic acid (RA) and CSF. The hDPSCs from an impacted third molar were isolated by mechanical and digestion and cultured. The cells have treated by 10(-7) µM RA (RA group) for 8 days, 10% CSF (CSF group) for 8 days and RA with CSF for 8 days (RA/CSF group)...

AIM: This study aims to investigate the effect of casein phos-phopeptide-amorphous calcium phosphate and three calcium phosphate (CPP-ACP and TCP) on increasing the microhardness of human enamel after induction of erosion. MATERIALS AND METHODS: A total of 26 healthy human-impacted third molar teeth were chosen, and their hardness measured using a microhardness testing machine. The samples were immersed in Coca Cola (pH = 4.7) for 8 minutes. Then, micro-hardness was measured again, and these samples were randomly divided into four groups (two control groups and two experimental groups)...

AIM: Removal of impacted third maxillary molar is frequently carried out without difficulties and low rate of intraoperative complications. The rare and particularly challenger to manage it is the third molar dislocation into the infratemporal fossa (IF). In this clinical report, the authors present their solution to manage and resolve this particular complication. METHODS: A 28-year-old woman was referred to the emergency rescue unit of the authors' hospital by her dentistry, after the attempt to extract the left impacted maxillary third molar...

PURPOSE: The current data suggest that the presence of lower third molars predisposes the patient to a greater risk of mandibular angle fracture. Thus, the present review sought to determine whether an association exists between the presence of a lower third molar and the occurrence of a mandibular angle fracture in adults and to assess the influence of third molar position according to the Pell and Gregory classification. MATERIALS AND METHODS: The present study was a systematic review and meta-analysis of analytical observational studies...

Mesenchymal stem cells derived from the human tooth germ (hTGSCs) are a heterogeneous cell population that can differentiate into osteogenic, neurogenic, and adipogenic lineages. The aim of this study was to compare the osteogenic differentiation capacity of STRO-1 positive (STRO-1+) hTGSCs and unsorted heterogeneous hTGSCs and to establish if STRO-1+ cells are more committed to osteogenic differentiation. HTGSCs were isolated from impacted third molar tooth germ tissues of adolescents, and a subpopulation of STRO-1+ hTGSCs was obtained by fluorescence-activated cell sorting...

PURPOSE: We aimed to compare the effect of dexamethasone, 8 mg, and diclofenac sodium, 50 mg, associated with codeine, 50 mg, on the control of pain, swelling, and trismus after extraction of impacted third molars. MATERIALS AND METHODS: Fifteen healthy patients with a mean age of 22.8 years (SD, 12.62 years) received a single oral dose of either drug 1 hour before each surgical procedure (left and right teeth). At 24, 48, and 72 hours after surgery, swelling was determined by use of linear measurements on the face and trismus was determined by maximal mouth opening...

PURPOSE: Experience has shown that in malpractice cases patients often claim certain information was not provided during the informed consent process. The purposes of this study were to determine how much of an informed consent video patients initially remember and how much is recalled when there is a hiatus from viewing the video to the surgery. PATIENTS AND METHODS: In this prospective cohort study, patients presenting for impacted third molar removal in an academic setting (n = 50) or a private office (n = 50) viewed an informed consent video and then met with the treating doctor for further discussion and signing of an informed consent form...

PURPOSE: Application of platelet-rich fibrin (PRF) during tooth extraction is able to accelerate wound healing, stimulate osseous and soft tissue regeneration, and reduce unwanted side effects. The aim of this meta-analysis was to investigate the effect of local application of PRF on controlling postoperative signs and symptoms after the extraction of an impacted lower third molar. MATERIALS AND METHODS: A systematic search of PubMed, Web of Science, Embase, and the Cochrane Library was performed to identify all studies published up to October 2016 that investigated the effect of PRF on lower third molar extraction...

PURPOSE: To compare the efficacy of preoperative submucosal injection of 4 mg of dexamethasone versus 40 mg of methylprednisolone in reducing postoperative sequelae after surgical removal of impacted mandibular third molars. PATIENTS AND METHODS: This prospective, randomized, double-blind study included 65 patients who required surgical removal of impacted mandibular third molars with Class II or position B impaction (Pell and Gregory classification). Patients were randomly assigned to 1 of 3 groups: dexamethasone, methylprednisolone, or placebo (control)...

BACKGROUND: "Kissing" or "rosetting" of molars are extremely rare phenomenon with limited cases in the dental literature. It was first described in 1973, refers to contacting occlusal surfaces of the impacted mandibular second and third molars. The aim of the present study was to report the incidence of kissing molars (KMs), classification, incorporated pathologies, and its management in a group of Turkish population. MATERIALS AND METHODS: The panoramic radiographs of the patients who referred to Gaziantep University Faculty of Dentistry between January 2012 and November 2014 for surgical treatment retrospectively were evaluated...

In order to compare the efficacy of lidocaine and articaine for pain control during third molar surgery, 160 patients presenting bilateral asymptomatic impacted mandibular third molars were selected. They received 1.8 mL of 2% lidocaine with epinephrine 1:100,000 during inferior alveolar nerve block. In group 1 (n = 80), an infiltrative injection of 0.9 mL of 2% lidocaine with epinephrine 1:100,000 was performed in buccal-distal mucosa of the third molar. Group 2 (n = 80) received 0.9 mL of 4% articaine with epinephrine 1:100,000 in the contralateral side...

BACKGROUND: Caries in second molar is common and prophylactic removal of the impacted teeth may be considered appropriate. Caries detection and restoration can be difficult and a restored second molar can undergo recurrent caries if the third molar is not removed prophylactically. In this study, the clinical findings related to impaction and its association with angular position and depth of impacted third molar were evaluated. MATERIALS AND METHODS: A retrospective descriptive study was carried out among the patients visiting the outpatient, department of Dentistry, RIMS, Ranchi...
