Inverted tooth impaction is a rare occurrence. Third molar impaction is the most extensively studied, and only eight cases of inverted third molars have been reported in a literature search of 40 years from 1973 to 2013. In a study, 43.4% of the premaxillary supernumeraries were inverted and 21.1% were transversely oriented, while occasional inverted central incisors have been mentioned in the literature. Severe dilaceration makes the management of this case a big challenge. The case of an 8-year-old boy with an inverted, rotated, and impacted upper left central incisor obstructed by an odontome is presented here...

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...

Bilaterally mandibular and maxillary fourth molars, concomitant to hypodontia, are uncommon. These dental anomalies, called hypohyperdontia, are rare and etiology is not well defined. Several complications may occur as a consequence of supernumerary teeth, such as teeth impaction, resorption of adjacent teeth, and development of cysts and tumors. The authors present an uncommon occurrence of three-fourth molars concomitant to hypodontia and dentigerous cyst associated with impacted mandibular second and third molars in a nonsyndromic patient...

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)...

Introduction: Surgical procedures require informed patient consent, which is mandatory prior to any procedure. These requirements apply in particular to elective surgical procedures. The communication with the patient about the procedure has to be comprehensive and based on mutual understanding. Furthermore, the informed consent has to take into account whether a patient is of legal age. As a result of large-scale migration, there are eventually patients planned for medical procedures, whose chronological age can't be assessed reliably by physical inspection alone...

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...

Mandibular tooth impaction is a very common finding and is usually associated with so many local and systemic causes in which the pathway of tooth eruption is obstructed or misdirected. The local causes are either a local bony lesion or an abnormal position of the adjacent tooth. The case presented here is associated with a very rare cause of impaction, which is the hamartomatus growth of the first and second molars causing the obstruction and leading to the impaction of the adjacent third molar tooth.
