“…In line with the studies suggesting that pathological change occurs more frequently after age 20 and is par- ticularly high among individuals aged 20-30, [21][22][23] our study does not correlate with the previous study, as the youngest patient recorded in our study is of 14 years and the oldest patient is of 72 years. Previous reports by various authors recommended age as an indication for surgical removal of impacted, unerupted, and embedded tooth, as the risk of surgical morbidity increases with age.…”

“…Many authors consider that the extraction of the LTM is reasonable in case of the developed pericoronitis, particularly in combination with deep and complicated caries, apical periodontitis, osteomyelitis, paradental cysts or abscesses [10,17,18,22]. However, a range of researchers, including those who conducted histological examination of the resected tissue, insist on the «preventive» extraction of the intact LTM relying only on the probability of the complications development, which indeed are more frequently observed in this region rather than in other places of a dental arch [6][7][8].…”

“…There is no consensus in the related reference sources on the issue of the indications for the extraction of the intact LTM in case of complications of their eruption. A range of authors, who identified more frequent development of pathological changes in paradental tissue in the region of the LTM, support an idea of the relevance of «preventive» extraction of the intact LTM [4][5][6][7][8][9]. Other authors highlight the relatively low frequency of complications in the «restricted» LTM, which evidences in favor of an expectant treatment [10][11][12][13].…”

The aim is to determine the clinical and morphological dependencies, which are important for diagnostics, treatment and prediction of outcomes of pathological processes in the region of the LTM with complicated eruption, as based on the study of histopathological changes of paradental tissue (mucous membrane, walls of retromolar pocket, alveolar bone tissue). Materials and methods: The materials of the study were 34 biopsy specimens of pathologically altered soft tissue and parodontium obtained as a result of pericoronectomy, extraction of the LTM and other surgical interferences performed based on the relevant indications in 28 patients in the region of the LTM with complicated eruption. Morphological and statistical research methods were used. Results: The local pathological processes, which chronologically precede the destructive changes in the hard tissue of a tooth (caries), are developed in patients of both genders with complicated LTM eruption in soft tissue of parodontium and the adjacent bone tissue of the alveolar wall in the majority of cases. As per biopsy examinations, the frequency of the main pathological processes in paradental tissue in case of complicated LTM eruption varies from 25 to 60 % of the number of biopsy specimens and occurs in various combinations in patients with different values of clinical parameters. The correlation relationships between the patients’ clinical data and the morphological parameters of damage to paradental tissue are weak, multidirectional and uncertain in the majority of combinations (considering the available number of biopsy specimens studied). The close certain positive dependence between the damage of the squamous epithelium and the inflammation activity in the lamina propria mucosae, covering the tooth: in the vast majority of cases, the presence of damaged epithelium (within the biopsy specimen) is associated with the inflammation of high activity, was established as based on correlation relationships between the morphological parameters of damage to paradental tissue. Conclusions: The found pathological changes and the correlations justify surgical tactics on paradental soft and osseous tissues that are directed on the LTM sparing.

“…(1,12,13) Some authors believe that all impacted third molars should be extracted whether they are symptomatic or not, because if they later become symptomatic, the risk of post-extraction complications can increase with the patient's age. (14)(15)(16) Conversely, other authors believe that due to lack of evidence and knowledge about the incidence of pathologies or the low rate of most complications associated with third molars, the decision to remove asymptomatic third molars is questionable. (13,14,(17)(18)(19)(20)(21) Recent studies suggest that incidence of pathologies associated with retained third molars is low; hence, the most appropriate treatment for asymptomatic impacted third molars in young adults might be observa-tion instead of prophylactic removal.…”

Impacted and partially erupted third molars can cause various symptoms and pathologies. The aim of this study was to determine the association between commonly observed pathological conditions and the impaction depth of lower third molar teeth. Materials and methods: In this retrospective study, 370 panoramic radiographs including 724 lower third molars were evaluated to assess several pathologies according to impaction depth. The patients were also examined clinically for pericoronitis. Impaction depth was defined according to horizontal indices in class I, II, or III, where none, less than half, or more than half of the crown was in the ramus of the mandible, respectively. The vertical indices for teeth, classes A, B, and C, were defined by the highest portion of the tooth being on a level with or above the occlusal plane, below the occlusal plane but above the cervical line of the second mandibular molar, or below the cervical line of the second mandibular molar, respectively. The data were analyzed using Chi-squared tests. Results: Of the teeth analyzed, 57%, 28.4%, and 14.6% were at vertical level A, B, and C, respectively. Of the 605 mandibular third molars, 363 (60%) were in horizontal class I, 212 (35%) were in class II, and 31 (5%) were in class III. Incidence of pericoronitis was significantly associated with partially erupted third molars and impactions of class AII (P = 0.028). Class A impaction showed a stronger association than classes B or C with all conditions (P = 0.04) except for bone loss and root resorption of second molars (P = 0.07). Conclusion: Class A impaction depth, where the highest portion of the tooth was on a level with or above the occlusal plane, was associated with more pathological conditions than classes B or C.
