“…It is present among European early modern humans (Table 3), but none of them is old enough to represent the ancestral lineage of Oase 1. The etiology of lingual bridging is poorly known, but its pattern of populational distribution suggests a strong genetic component (57). As previously argued (58), its presence in moderate frequencies among European early modern humans, now including Oase 1, implies some genetic contribution of the Neandertals to those subsequent populations.…”

The 2002 discovery of a robust modern human mandible in the Peştera cu Oase, southwestern Romania, provides evidence of early modern humans in the lower Danubian Corridor. Directly accelerator mass spectrometry radiocarbon ( 14 C)-dated to 34,000 -36,000 14 C years B.P., the Oase 1 mandible is the oldest definite early modern human specimen in Europe and provides perspectives on the emergence and evolution of early modern humans in the northwestern Old World. The moderately long Oase 1 mandible exhibits a prominent tuber symphyseos and overall proportions that place it close to earlier Upper Paleolithic European specimens. Its symmetrical mandibular incisure, medially placed condyle, small superior medial pterygoid tubercle, mesial mental foramen, and narrow corpus place it closer to early modern humans among Late Pleistocene humans. However, its cross-sectional symphyseal orientation is intermediate between late archaic and early modern humans, the ramus is exceptionally wide, and the molars become progressively larger distally with exceptionally large third molars. The molar crowns lack derived Neandertal features but are otherwise morphologically undiagnostic. However, it has unilateral mandibular foramen lingular bridging, an apparently derived Neandertal feature. It therefore presents a mosaic of archaic, early modern human and possibly Neandertal morphological features, emphasizing both the complex population dynamics of modern human dispersal into Europe and the subsequent morphological evolution of European early modern humans.

“…23 In some cases, however, part of the course of this nerve may involve an intra-osseous component. 24,25 Anatomical variabilities such as this, or variation in the height at which the nerve to mylohyoid branches off the IAN, may ultimately influence whether this nerve is anaesthetized during an IANB. This is relevant for local anaesthesia as the nerve to mylohyoid can provide accessory innervation to mandibular teeth.…”

A thorough knowledge of the anatomy of the pterygomandibular space is essential for the successful administration of the inferior alveolar nerve block. In addition to the inferior alveolar and lingual nerves, other structures in this space are of particular significance for local anaesthesia, including the inferior alveolar vessels, the sphenomandibular ligament and the interpterygoid fascia. These structures can all potentially have an impact on the effectiveness of local anaesthesia in this area. Greater understanding of the nature and extent of variation in intraoral landmarks and underlying structures should lead to improved success rates, and provide safer and more effective anaesthesia. The direct technique for the inferior alveolar nerve block is used frequently by most clinicians in Australia and this review evaluates its anatomical rationale and provides possible explanations for anaesthetic failures.Keywords: Inferior alveolar nerve block, dental anaesthesia, mandibular nerve, sphenomandibular ligament, lingual nerve.Abbreviations and acronyms: IAA = inferior alveolar artery; IAN = inferior alveolar nerve; IANB = inferior alveolar nerve block; IAV = inferior alveolar vein; LN = lingual nerve; PVP = pterygoid venous plexus.

“…It was asserted to have a genetic trait and be a useful genetic marker for population related studies (Kılıc et al, 2010;Ossenberg, 1974;Jidoi et al, 2000). Even though the affinity for certain population groups was falsified (Lundy, 1980), bony variations such as mylohyoid bridging may be reliable markers (Sawyer, 1990).…”

SUMMARY:Bilateral mylohyoid bridging, hyperplasia of the coronoid process and bifid condylar process were detected in a human mandible. It is of great interest that such rare morphological anomalies can occur in the same mandible. Since sound understanding of the anatomical variations of the mandible, in conjunction with a careful pre-operative review of radiographs, are essential in the safe and complete performance of surgical and prosthetic rehabilitation, the authors of the present report believe that this case may add to the existing literature.
