OBJECTIVE Radiographic evaluation of the third molar tooth to determine its position and degree of development is an important part in diagnosis and treatment planning, as well as in forensic dentistry procedures. The objective was to investigate the developmental stages of third molars in relation to chronologic age, gender and location (maxillary/mandibular) in an Iranian population. MATERI...

third molar eruption is an unpredictable event. occasionally, mandibular third molars undergo angular changes in young adults. this rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the impaction worse. a rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.

To evaluate the effect of third molar impaction and impaction-related parameters on development. Panoramic radiographs (N=3972) from 473 males 558 females between 3.2 23.5 years old were analysed. Three examined: hindering contact adjacent second molar, retromolar space availability (only in lower molars), angulation molar. From separate parameters, a definition for was derived. Third molars’ d...

BACKGROUND First, first permanent molars (FPMs) of poor prognosis are often planned for extraction at an 'ideal time' so that second permanent molars (SPMs) erupt favourably to replace them. However for lower FPM extractions, timing is not an accurate predictor of success. OBJECTIVE The aim of this study was to identify additional radiographic factors that could better predict the degree of s...

conclusions the relationship between calcification of tooth and maturation of cervical bones was significant. this suggested that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator. results all correlation values obtained were statistically significant (p < 0.001). correlations between dental development and skeletal maturity stage due to cv...

  Abstract Introduction: Third molars  are the last teeth to grow and require more attention in the oral cavity because they can leave pathological effects. Considering the controversy clinical decisions about asymptomatic third molars, dentists’ lack of attention to over third molars developed during therapeutic recom-mendations for patients, and limited evidence about the effects of asympt...

introdouction: 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 s...
