The purpose of this study was to evaluate the pulp chamber morphology in primary mandibular molars using spiral computed tomography (SCT).Sixty extracted primary mandibular molars were scanned using SCT for the (i) distance between the central fissure to furcation, (ii) distance between the central fissure to the floor of the pulp chamber, (iii) height of the pulp chamber (roof-floor), (iv) distance between the floor of the pulp chamber to the furcation. The mean and standard deviation was analyzed using statistical package for the social sciences (SPSS) program.The results of this study show that the average mean distance from the central fissure to the floor of the pulp chamber is 5.07 mm in first mandibular primary molar and 5.54 mm in second mandibular primary molar.It can be concluded that the greatest depth to which a bur can go during access opening without perforating the furcation in first primary mandibular molar is 5.07 mm and 5.54 mm in second primary mandibular molar.

Human beings are being subjected to a variety of disease processes, a majority of which can be cured. However, cancer remains an endangering disease that affects various body parts. Though cancers can be prevented by various therapeutic modalities, the patient survival and the prognosis are questionable, as they are detected at very late stages. The aim of improving the prognosis lies in an early detection of the cancer, which can be brought about by an analysis of the changes in the cellular biomolecules.

Myoepithelioma is a benign salivary gland tumor in the head and neck region, accounting for 1-1.5% of all glandular tumors. The diagnosis is rendered histopathologically, and it includes the proliferation of myoepithelial cells, without chondroid or myxochondroid stroma and ductal components (up to 5% of ductal component is acceptable). In our case report, this lesion has occurred in a 46-year-old female patient, and presented as well defined, nodular growth on the right posterior palatal region. Bony erosion and invasion were observed radiographically, and the lesion was excised surgically, with 1-2 cm of clear margin. The microscopic features included proliferating tumor sheets, composed of bland looking spindle and plasmacytoid shaped myoepithelial cells, and few cells showed clear cytoplasm, which were confirmed immunohistochemically as myoepithelial cells. Thus, the final diagnosis of benign myoepithelioma was rendered and no recurrence had been reported so far in the regular follow-up.

Background: Tooth development may be hampered following traumatic injuries to maxilla or mandible. The developmental deviations that occur in a tooth bud in the line of a jaw fracture range from agenesis to hamartomatous proliferation. Odontomas are benign odontogenic hard tissue tumors, which are hamartomas characterized by slow growth and non-aggressive behavior. 'Erupted odontoma' is a term used to specifically denote odontomas, which are exposed into the oral cavity. These are rare entities with only 25-30 cases being reported so far in the dental literature. Case Description: This clinical report is pertaining to a rare case of an erupted odontoma in an adolescent patient which was presenting as a hard tissue outgrowth along with an extra-oral sinus in the posterior mandibular region. The surgical excision of the odontoma along with the associated malformed teeth resulted in resolution of pain and sinus discharge associated with this lesion. Conclusions: Erupted odontomas need to be considered in the differential diagnosis of hard tissue projections or outgrowths in the site of past maxillofacial injuries. Surgical excision of these lesions enable resolution of patient symptoms associated with this condition as evidenced in the present case and in other cases cited in the literature. The erupted odontoma attached to malformed molars and presenting with signs and symptoms suggestive of osteomyelitis is a rare combination of developmental aberrations following maxillofacial injury.

The subject of sleep medicine, for dental profession in general and prosthodontists in particular, continue to offer great challenges and opportunities in terms of diagnosis, treatment planning and treatment based on qualitative evidence. Although the role played by the prosthodontists is still in its infancy, there is much to learn and understand in the rapidly evolving field of sleep medicine as the recognition of co-managing patients with sleep disorders by the prosthodontists is fast becoming a reality. This article discusses at length the prosthodontic perspectives of the research in the field of sleep medicine, particularly on obstructive sleep apnea.

Background The aim of this investigation was to compare the effectiveness of 3% sodium hypochlorite (NaOCl), 2% chlorhexidine, 1% peracetic acid, and 10% povidone-iodine in the rapid disinfection of Resilon (Pentron Clinical Technologies, LLC, Wallingford, CT) and gutta-percha cones contaminated with Enterococcus faecalis and Bacillus subtilis. Methods Two hundred fifty-six samples consisting of 128 gutta-percha cones and 128 Resilon cones were used in this study. The materials were tested for disinfection according to the type of solution (3% NaOCl, 2% chlorhexidine, 1% peracetic acid, or 10% povidone-iodine), the time of exposure to each solution (1 or 5 minutes), and the type of microorganisms (E. faecalis or B. subtilis). Subsequent to the disinfection, samples were placed in test tubes containing 10 mL Mueller-Hinton broth and incubated at 37 C for 7 days. All test tubes were observed at 24-hour intervals and visually checked for turbidity, signifying microbial growth. Results In this study, 1% peracetic acid showed the best results for both 1 minute and 5 minutes of disinfection, 2% chlorhexidine showed the second best results although it was statistically at par with peracetic acid, and 3% hypochlorite ranked third in disinfection; this was statistically significant when compared with peracetic acid and chlorhexidine. Disinfection by povidone-iodine was the least within all the groups for both contact times although disinfection for 5 minutes showed better results than disinfection for 1 minute for gutta-percha. Conclusions The outcome of this study confirmed the efficacy of 1% peracetic acid and 2% chlorhexidine in the rapid disinfection of both Resilon and gutta-percha. © 2013 American Association of Endodontists.

Contamination and subsequent retention of foreign bodies within wound surfaces may negatively influence healing following maxillofacial injuries. Larger foreign bodies that produce embedded or impalement injuries of soft tissues are easily detected. However, smaller contaminants, such as sand, gravel, food particles, wood splinters, and glass fibers, may not be easily identified in the initial examination, and their remnants may remain within the injury site even after debridement. Tissue reactions depend on the host response, type of foreign body, and nature of the wound surface. The purposes of this report are to: (1) detail the diagnosis and management of a peripheral pulse granuloma following retention of food particles within gingival sulci during a dental injury; and (2) provide a brief review of the diagnosis of foreign body-induced granulomas following maxillofacial injuries in children.

Dental caries an ever growing public health problem is not much amenable to existing preventive measures. The aim of this study was to compare and evaluate the effectiveness of mouth rinse containing chicken egg yolk antibodies generated against whole cell antigen and cell associated glucosyltransferase enzyme (CA-GTF) of Streptococcus mutans in preventing recolonization of S.mutans in dental plaque of human volunteers. The experimental period was up to 210 days. At the end of the experimental period, in the experimental group treated with IgY to whole cell S.mutans reduction in reestablishment of S.mutans from base line value was 67.66% and the group treated with IgY to CA-GTF it was 89.66%. But in the control group treated with non-immune IgY reestablishment was greater than its baseline value with the increment of 9.67%. The promising results in the experimental studies vividly reveal that immune IgY to CA-GTF has significant influence in preventing caries development.

Rapp-Hodgkin syndrome (RHS) is a rare type of autosomal dominant disorder characterized by association of ectodermal dysplasia (ED) with cleft lip/palate. The main features include dry, brittle hair with alopecia in adulthood, dental anomalies (hypodontia, microdontia with delayed eruption, fissured tongue, and retruded maxilla), hypohidrosis, dysplastic nails, and clefting. Palmar-plantar keratoderma is seen frequently. RHS has signs and symptoms that overlap considerably with those of ankyloblepharon-ED-clefting syndrome and ectrodactyly-ED-clefting syndrome. This manuscript discusses a case of RHS, one of the four members in three generations who had ED with variable degree of involvement of hair, teeth, nail, and sweat glands.
