Objective: To investigate whether the use of cone beam CT (CBCT) changes the diagnosis of external root resorption (ERR) or marginal bone loss (MBL) involving a second molar adjacent to an impacted third molar. Methods: A systematic search was applied in PubMed, EMBASE, Scopus, Web of Science, LILACS, Google Scholar, OpenGrey, and ProQuest. Studies assessing the detection of ERR or MBL in a second molar adjacent to an impacted third molar through CBCT and panoramic radiography (PAN) were included. Prevalence and agreement between PAN and CBCT on the detection of ERR and MBL were collected. The risk of bias was assessed using the MAStARI. Results: A total of 593 papers were identified, and after a 2-phase selection, 5 studies were included in the narrative synthesis. Regarding ERR, its prevalence in PAN was reported from 5.31 to 19.5% and from 22.8 to 62.0% in CBCT. The percentage of agreement varied from 28.5 to 74.0%. The prevalence of MBL varied from 21.9 to 62.9% in PAN, while those values varied from 21.6 to 80% in CBCT images. The percentage of agreement between PAN and CBCT for the detection of MBL ranged from 66.0 to 85.0%. Four studies presented low risk of bias and one had moderate risk. Conclusions: More ERR and MBL are assessed in CBCT compared to PAN. There is a considerable agreement between PAN and CBCT assessment of ERR and MBL, however, mostly related to the absence of the pathology rather its presence.

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.

SUMMARYThe development of the maxillary teeth in cattle was studied by recording eruption into the oral cavity and by radiographic examination following bisection of the skull. Observations of second molar intra-oral eruption showed that varying stages were seen at different ages. Radiography of the teeth allowed determination of the degree of crown and tooth development in the permanent premolar and molar teeth as well as stages of temporary premolar tooth resorption. Radiographic inspection showed that in the same animal all the permanent maxillary cheek teeth except the first premolar were less well developed than their mandibular counterparts. It was suggested that the intra-oral eruption of the second maxillary molar and radiography of the maxillary teeth provided a better method of age estimation in cattle than the traditional one of examining the intra-oral eruption of the incisor and canine teeth.

Pathology of an eruption of wisdom teeth is importance for a military odontology because the vast majority of the military contingents on age coincides with time of their physiological eruption (16-40 years). In work, on the basis of clinic-radial methods of a research, features of a teething of wisdom at young people of military age are studied and analyzed 3D-tomograms and orthopantomograms of 325 servicemen aged from 18 up to 27 years. During work estimated existence of wisdom teeth on top and lower jaws, extent of their eruption, existence of a retention (or dystopias) and also an adentia or loss of wisdom teeth. It was established that most often eruption of the third molar teeth of jaws at recruits occurs at the age of 23-27 years, at the same time at a series of recruits eruption of the lower wisdom teeth usually is followed by various complications, such as pericoronitis, an acute purulent periostitis of a mandible, a false «acute periodontitis» of the lower second molar tooth that becomes perceptible at mesial shift of a wisdom tooth and dense contact of its coronal part with a distal root of the second molar tooth. The essential value for a full-fledged teething of wisdom has their situation in an alveolar process (part) of a jaw, and further - in dentition. It in many respects defines a clinical picture of the shown eruption complications and also tactics of stomatologic treatment - orthodontic treatment, surgical treatment or their combinations. The infectious and inflammatory complications bound to the complicated their eruption (85,93% of cases) served as the reasons of an exodontia of wisdom. In 14,07% of cases wisdom teeth on both jaws were extracted in a planned order in connection with the forthcoming orthodontic treatment on elimination of dentoalveolar anomalies. Thus, terms and features of a teething of wisdom at recruits need to be considered in clinical practice of a military odontology as their military service can pass in specific living conditions and activity of troops and health service, and at complications of a teething of wisdom the acute stomatologic surgical management, including stationary is in most cases necessary.

At the beginning of the growth, tooth inclination is mesioangular, then move gradually to come into contact with thedistal surface of the second molar and further commit to sliding movement parallel to second molar axis. This positionwill be retained to achieve the eruption way to oral cavity. However, the last decade reported incidence increasedimpaction of the third molar teeth in the lower jaw. This study was aimed to study the level of pre-eruption of mandibularthird molar in the population group aged 14-17 years to predict the risk of tooth impaction or not. Differentiatedpopulations on cluster I, age 14-15 years old; group II, 15.1-16 years old; and group III 16.1-17 years old. Researchcarried out by clinical observation and measurement of at Department of Radiology in Jember University with 48people selected based on predetermined criteria. X-ray projection was exposed by paralleling technique on the lowerthird molar teeth, left and right. The results showed 43.75% of 14-15 year old group had the third molar angle interval50-56°; 15.1-16 year age group, 80% have 57-70° angle interval, and 16.1-17 years age group, 46.67% has angularinterval 64-70°. It was concluded that a large interval of the third molar angle increase due to the increased of age,and the angle is different between groups based on gender.

AbstractThere have been infrequent case reports of bilateral root resorption in the lower second molar secondary from impacted third molar removal with bone regeneration without pain. Root resorption is commonly observed during third molar surgical impaction that affects mandibular second molars. The bone regeneration into the adjacent affected tooth is evident simply after the surgical extraction of the impacted tooth. However, there have been a few previous reports on the prognosis of the remaining resorbed tooth. Most dentists often choose to extract them when damaged if root resorption is observed. This report case involved bilateral root resorption of the lower second molar due to lower adjacent impacted third molar teeth and bone regeneration without pain sensation. After surgical extraction of bilateral lower impacted third molar teeth, the remaining teeth retained vital pulp and survived as functional teeth.

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.
