The Oblique Lateral Jaw Radiograph has been used as a routine diagnostic x-ray view for many years as an aid to orthodontic diagnosis and for the assessment of the positions of unerupted third molar teeth. Many methods for obtaining clear undistorted views of the teeth have been suggested from a freehand setting up of film, patient and x-ray tube, to the use of simple orientated devices. The present article describes a method of standardizing the relationship of film and x-ray tube to one another so that it is only necessary for the radiographer thereafter to place the patient on the film area in a manner depending on whether a view. is required of the third molars only or of the complete upper and lower buccal segments.

Abstract OBJECTIVE: To investigate the relationship between the presence and dynamics of mandibular third molar development and the occurrence and amount of late mandibular incisor crowding. MATERIALS AND METHODS: Dental plaster casts and panoramic radiographs of 72 orthodontically untreated subjects from the Nittedal growth study, Norway were analysed. The subjects were recalled for check-up at 12, 15, 18 and 21 years of age. Mandibular incisor crowding was assessed using the Little’s irregularity index and dental maturation of the third molars by the Cameriere’s index.RESULTS: The majority of the subjects (64%) had ≥1mm increase in irregularity; 22% experienced increase of 0.1-0.9mm and 14% had unchanged or decreased irregularity. Incisor irregularity increased with age, regardless of absence or presence of third molars. The amount of change in incisor irregularity from 12 to 21 years did not differ significantly between subjects with hypodontia of third molars, extraction and those with third molars present. No differences were observed between erupted, unerupted or impacted third molars. No correlation was found between the amount of change in irregularity and maturation of the third molars.CONCLUSIONS: Occurrence and amount of mandibular late incisor crowding is not significantly influenced by presence or development dynamics of mandibular third molars.

Objectives: To evaluate impacted mandibular third molar tooth region and obtain linear measurements using CBCT images and to assess the relationship between the impacted third molar and the mandibular canal. Methods: CBCT scans of 351 patients (208 females, 143 males) were assessed. Age, gender, and impaction site were recorded for each patient. The relationship of third molars with the vertical axis of second molars, 2nd molar resorption and the relationship between third molar apices and the mandibular canal were assessed. In addition, the distance between ramus and second molar, mesiodistal width of the third molar, the angle between third molar and second molar, and width of the third molar capsule were measured. Binary Logistic Regression, Chi-Square Test, and General Linear Model were used for statistical analysis. Results: The highest percentage of impaction was found for mesioangular followed by transversal and vertical. The transversal impacted third molars revealed a significant association with adjacent second molar root resorption (p<0.001). There was a statistical significance between the second molar resorption and distance between ramus and second molar (p<0.001). The mesioangular impacted third molars revealed significant relation with the mandibular canal (p<0.05). The most frequent variation found was the dental canal followed by the retromolar canal. In general, higher measurement values were obtained for men when compared to women (p<0.05). Conclusion: CBCT assessment of the third molar region provided useful information regarding impacted mandibular third molar surgery operations.

The Relationship

The objective of this study is to discuss problems associated with dental retention through three clinical cases of mandible fractures related to the presence of retained lower third molars, emphasizing the possibility of mandible fractures resulting from this or from the extraction procedure. The three evaluated patients had a fracture in the mandible angle. The third molars were present in all the cases, as was the relationship of the fracture with the teeth. After evaluating the three cases and reviewing literature, it is believed that the presence of the retained lower third molars and the surgical procedures for their extraction increase the risk of mandible angle fractures.

Negative Effect

Subject. The issues of indications, contraindications and the optimal timing for the removal of abnormally located lower third molars remain relevant in dentistry. Numerous evidence has been accumulated of their negative impact on the formation of the dentofacial system, however, X-ray patterns of patients with this pathology in the process of their formation, development and change in the angle of inclination, as well as the growing problems associated with the growth of these teeth in the dentition and bite have not been studied. The goal is to study the dynamics of the position of the rudiments of the abnormally located lower third molars in the process of their formation and growth and their influence on the state of the dentofacial system as a whole. Methodology. The study involved 28 patients with abnormally located impressive lower third molars, which were divided into 3 groups: in the first (8 people), the second molars were at the teething and growth stage, in the second (12 people) the second molar was in the occlusal plane at the stage closed apex, in the third (8 people) there was a multiple abnormal position of the mesially located teeth from the third molar. All measurements were performed using a virtual measuring device in the image mode of slices with Galileos Viewer software. Results. According to our results, a significant scatter was recorded in the timing of the formation of third molars from the period of mineralization of the crown of the teeth (12―15 years) to the end of growth and root formation (18―23 years). After 23 years, the roots of the abnormally located lower third molars in the patients examined by us had radiological signs of the end of formation (closed apex). Conclusion. Impact lower third molars continue their growth and have a negative effect on the condition of the teeth located mesial. This fact does not depend on concomitant orthodontic pathology, nor on the methods of orthodontic treatment (removable or non-removable equipment).

The Forensic Anthropology and Forensic Dentistry, in one of its branches, aim to base skills making possible to estimate the age period for an individual, through factors such as tooth mineralization and bone development. This paper aims to report on two cases from Scientific Expertise Center - Renato Chaves, Belém- PA, where two individuals after committing crime, were referred to under 18s without supporting documents. Through data collected in the archives of the Scientific Expertise Center, an analysis of the mineralization of the teeth were made, highlighting the third molars by panoramic radiography; as well as the study of bone development of the hands and wrists of individuals through radiographs. After, the analysis was compared to surveys conducted by Nicodemos, Moraes and Médici-Filho, befitting the chronology of mineralization of permanent teeth among Brazilian citizens together with the work of Greulich-Pyle, Radiographic correlation concerning the chronology of the development of the hand and wrist. As a result of the analysis, it was obtained, for case 01, an estimated age of 17; and for case 02 the estimated age was between 18-19 years.
