Odontomas are the most common type of odontogenic tumor occurring within the jaws and are frequently associated with the retained deciduous teeth interfering with the eruption of permanent teeth. Compound odontomas are usually diagnosed in the anterior portion of the jaws and resemble tooth-like structure. These are usually asymptomatic. Complex odontomas are normally diagnosed in the posterior part of the jaws and consist of a disorganized mass with no morphologic resemblance to a tooth. The present case report of a 16-year-old female is a typical case of compound odontoma in the maxillary anterior region associated with retained deciduous incisor, which also resulted in failure of eruption of the permanent maxillary right central incisor. An intraoral periapical radiograph revealed the presence of a radio-opaque tooth-like structure in the apical region of retained deciduous incisor and an impacted permanent right central incisor whose path of eruption was impeded by the structure. Treatment included the surgical removal of the lesion followed by orthodontic extrusion of the impacted incisor. Follow-up was done for one 1 year and no recurrence was seen.

Background: Organic tissue dissolution is considered as one of the most important and desirable property of endodontic irrigant, any soft tissue remnant, harboring bacteria, left in the canal after endodontic therapy may be the cause of failure. Aim: The present study aimed at assessing and comparing the human pulp dissolution (thereby eliminating the bacteria) capacity of some potential endodontic irrigants viz., sodium hypochlorite (NaOCl) (2.5% and 5.25%), chlorine dioxide (5%) and peracetic acid (5%). Materials and Methods: Forty human pulp specimens from extracted premolars were taken and weighed. They were immersed in test solution for 30 min, dried on filter paper and weighed again. The percentage weight loss was calculated and statistically analyzed. Conclusion: It can be concluded that NaOCl showed the best tissue dissolution capacity, followed by 5% peracetic acid.

Barodontalgia is the oral pain caused by the changes in the pressure caused due to altitude changes either on deep sea diving or inflight conditions. Barodontalgia is one of the important clinical entities which present with such overlapping signs and symptoms, that in normal clinical setup the pain due to barodontalgia goes unnoticed. Also the literature available in textbooks is also less informative and revealing of the nature of pain caused due to barodontalgia. Hence this article focuses on those untouched aspects of barodontalgia which are to be paid attention.
