INTRODUCTION: Bone removal is necessary for extracting the third molars that are erupted, partially erupted, and/or impacted in bone. Hence, it is necessary to choose a surgical method or instruments that conform to anatomic landmarks and are based on physiological principles. Many authors have reported injuries to the adjacent tooth, especially the distal part of periodontium after removal of second molar. Hence, the present study was undertaken to assess and compare the surgical and postsurgi-cal outcomes of third molar removal using piezoelectric surgery and rotary bur...

Iatrogenic lingual nerve lesion is a well-known and unfortunate complication after mandibular third molar removal. Occasionally, the nerve injury can cause severe neuropathic pain.Here, the authors present the history of 2 patients with lingual nerve injury due to mandibular third molar removal, and with severe neuropathic pain in the craniomandibular region. Pharmacotherapy and physiotherapy did not reduce the pain, and ultimately, the lingual nerve was surgically explored. Scar tissue and a lingual nerve neuroma were observed and resected in both patients...

The objective of the present study was to test the hypothesis that nutrient deprivation by effective isolation should inactivate causative saccharolytic bacteria occupying carious lesions. Vital maxillary third molar teeth were prepared by removing only the superficial necrotic material, leaving behind infected dentinal matrix, before the cavity was sealed with glass ionomer cement (GIC). Before sealing, lesions were biopsied to provide reference bacterial DNA for microbial analysis. After an interval of 10-12 months, the teeth were extracted and, after careful removal of GIC restoration, the underlying dentine was biopsied again for post-treatment microbial analysis...

Extractions of mandibular third molars are a common procedure in dental practice. In cases where a close anatomical relationship of the root and the inferior alveolar nerve exists, the risk of transient or even permanent nerve injury increases. Nerve injury is difficult to manage and symptoms may cause severe patient discomfort, i.e. lifelong dysesthesia, i.e. painful sensation of the lower lip and chin area on the affected side. An alternative surgical procedure is coronectomy, which has first been described 25 year ago...

The study on the efficacy of oral analgesics reported that no single class of drug is effective in post-surgical dental pain. Pain following removal of third molar is most commonly used and widely accepted acute pain model for assessing the analgesic effect of drugs in humans. Reports demonstrated that analgesic efficacy in the human dental model is highly predictive. The high incidence of false-negative findings in analgesic investigations hinders the process of molecular discovery. Molecular mechanism of post-surgical pain is not known...

Mandibular third molar impaction causes many problems in the lower jaw. It has been assumed, for example, that impacted third molars are the cause of recurrent problems following orthodontic treatment. In order to prevent problems surgical removal of third molar buds, a germectomy, was proposed. An important factor was to predict the development of the third molar. In doctoral research, this was investigated. The causal relationship between the eruption of third molars and crowding of the lower front has never been proven...

BACKGROUND: Although the removal of impacted third molars (I-M3s) is common in dental clinics, the decision to retain or remove asymptomatic non-impacted third molars (N-M3s) presents a significant challenge. This study investigated the influence of N-M3s on the pathologies of the adjacent second molars (A-M2s). METHODS: The clinical status of M3s was evaluated, and the presence of distal caries, the external root resorption (ERR) and the alveolar bone loss of A-M2s were assessed by orthopantomograms (OPGs)...

Analysis of adjacent tooth resistance is essential in wisdom teeth extraction to prevent adjacent tooth trauma, however it lacks adequate attention nowadays. This study aims at suggesting special extraction methods based on adjacent tooth resistance analysis for prevention of adjacent tooth damage. In this study, 136 complicated mandibular third molars extracted using piezosurgery were reviewed and classified based on the adjacent teeth resistances shown in orthopantomogram (OPG) during their mesio-distal rotations: degree I refers to teeth with no adjacent teeth resistance; degree II refers to teeth with resistance released after mesial-half crown sectioning; degree III refers to teeth which still had resistance after mesial-half crown sectioning...
