Rigidity, retention, and resistance of titanium versus double taper light root canal posts: An in vitro evaluation

Aim: to evaluate and compare the physical properties of titanium posts and double taper (DT) light posts. Materials and Methods: Sixty posts (30 titanium post and 30 DT light post) were selected and divided into three groups. In Group I: Ten posts of each type were subjected to a three-point bending test. In Group II: 20 posts extracted maxillary central incisors were restored with ten posts of each type and subjected to tensile loading. In Group III: 20 posts extracted maxillary central incisors were restored with ten posts of each type and subjected to compressive loading at an angle of 135°. Results: The results showed that DT light posts were significantly less rigid (P <0.001), more retentive and significantly less resistant to fracture (P <0.001) as compared to titanium posts. Conclusion: It is suggested that although the DT light post system does not completely fulfill the requirements claimed by manufacturer but it would meet the requirements to combat the physiological forces operating in the oral cavity

Neurological manifestation of Vitamin D deficiency

Idiopathic intracranial hypertension, also known as pseudotumor cerebri, is a disorder with raised intracranial pressure, headache, papilledema, visual disturbances with a normal cerebrospinal fluid examination, and normal neuroimaging. It is rare in the pediatric population and may occur as a manifestation of underlying disorders. Vitamin D deficiency is a common deficiency in the pediatric age group. However, neurological manifestations are rare. Here, we present the case of a 5-year-old male child who presented with headache, vomiting, and hypertension; however, the neurological examination was normal but the neuroimaging was suggestive of pseudotumor cerebri. Appropriate investigations were done. The most likely cause of pseudotumor cerebri in this patient was the deficiency of Vitamin D. We have reported this case as pseudotumor cerebri is a rare neurological manifestation of Vitamin D deficiency.</jats:p
