This report describes the case of an 8-year-old boy that was referred to endodontic and orthodontic treatment after suffering an injury that led to intrusion of the maxillary right permanent central incisor, palatal displacement of the upper right lateral incisor, and root fracture of both central incisors. Both injured teeth were immature and had open apices. The intruded tooth was repositione...

ciduous canines were found on the right side.(Fig. 1, 2) There was previous history of extraction of maxillary and mandibular deciduous canines on the left side 2 months prior. Radiographic investigation using orthopantomogram was carried out and showed bilateral maxillary and mandibular impacted permanent canines.(Fig. 3) There were no associated odonDear Editor, Detailed radiographic study us...

Traditional right ventricular pacing prolongs the electrical and mechanical activation of the heart, which reduces the pump function, and in selected patients may lead to pacing-induced heart failure. Pacing the His bundle preserves the normal or near-normal activation pattern of the ventricles that prevents the detrimental effects of right ventricular pacing. This review discusses the techniqu...

A harpoon accidentally entered the right eye of a 15-year-old boy. No loss of consciousness occurred. After neuro-radiological assessment, the object which had penetrated the sphenoid sinuses was removed without mishap. He made a good recovery but has, as permanent deficits, an inferotemporal field defect, diminished visual acuity with optic atrophy, a sensory pupillary defect and right ptosis....

In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...

INTRODUCTION A dentigerous cyst is the most common developmental odontogenic cyst and is frequently noted as an incidental finding on radiographs. The most common teeth affected are impacted mandibular third molars and permanent maxillary canines. This case involves a dentigerous cyst encompassing the right and left impacted mandibular canines and crossing the midline. This is, to the best of o...
