The role of the fissure morphology in caries prevalence of the first permanent molar in Libyan children. |
p. 107 |
SM Omar, SH Meguid PMID:10635135Dental caries is one of the commonest of all dental diseases and is the main cause of loss of teeth in young people. It is a common belief that the high caries susceptibility of occlusal surfaces of posterior teeth is directly related to the morphology of the pits and fissures. Occlusal fissures are deep invaginations of enamel, they can be classified into V-type: Wide at the top and gradually narrowing towards the bottom U-type almost the same width from top to bottom. I-type an extremely narrow slit IK-type extremely narrow slit associated with large space at the bottom Y-type wide at the top and suddenly narrowing towards the bottom. |

Compound composite odontoma in primary dentition--a case report. |
p. 111 |
S Tandon, M Radhika PMID:10635136Compound composite odontoma, is a tumor formed by the overgrowth of transitory or complete dental tissue, made up of one or more rudimentary teeth. Although odontomes are considered to be quite common of odontogenic tumors, these rarely occur solely in primary dentition. This paper is a report of case of a compound composite odontoma, five year old child who presented to the Department of Pedodontics and preventive Dentistry, College of Dental Surgery, Manipal. |

Comparison of sealing efficacy of materials placed in lateral root perforations--an in vitro study. |
p. 115 |
MS Gulati, N Grewal, A Saini PMID:10635137An endodontic perforation interferes with the principal goal of sealing the root canal system. An in vitro study was conducted on comparative efficacy of three materials-Dispersalloy, Cavit and Prisma VLC Dycal when placed in lateral root perforations in cervical third areas. Root canals were prepared and irrigated thoroughly. Perforations were made with No. 2 round bur and sealed with Dispersalloy, Cavit and Prisma VLC Dycal. Dispersalloy Group I showed best sealing ability. Prisma VLC Dycal Group I too was comparable to Dispersalloy Group I in its sealing ability, followed by Cavit Group II, Prisma VLC Dycal Group II, Dispersalloy Group II in that order. Cavit Group I was least effective in sealing perforations. |

Foreign body in a mandibular permanent molar--a case report. |
p. 120 |
AR Prabhakar, N Basappa, OS Raju PMID:10635138A thirteen-year-old boy was examined in the Department of Pedodontics during a school-screening programme. On examination the left mandibular first permanent molar was found to be grossly destroyed. On radiographic evaluation a radio opaque screw shaped foreign object was seen in the pulp chamber of the said tooth. Retrieval of the foreign object was tried but the attempt was unsuccessful and an extraction was planned. A case of a unique foreign object in the pulp chamber of the tooth is reported. |

Comparison of sealing ability of three different root canal sealers--an in vitro study. |
p. 122 |
NS Jayalatha, S Kuriakose, KL Saradadevi PMID:10635139The main objective of endodontic therapy is complete obturation of the root canal system after it has been adequately prepared and sterilised. A wide variety of root canal sealers are available for obturation of the root canal system. A number of different invitro methods have been used to evaluate the sealing ability of endodontic filling materials. By combining one or two tests it may be possible to obtain information about sealing ability of the test material. Therefore, the present invitro study compared the sealing ability of three different root canal sealers, namely Sealapex, AH-26 and ZnOE by two different methods, bacterial leakage and dye penetration. The results showed that AH-26 has the maximum sealing ability followed by Sealapex and ZnOE. |

Congenital gingival granular cell tumor--a case report. |
p. 128 |
N Kalra, P Chopra, S Malik PMID:10635140Presented here is a case report of a congenital granular cell tumor commonly known as congenital epulis. It has been found to be ten time more common in females as compared to males. The most common presenting problem is that of difficulties in feeding and respiration. Surgical excision is indicated in case the above problems are present. In the absence of any respiratory or feeding difficulties it is advisable to wait for spontaneous regression. |

Shear bond strength of resin-modified restorative glass-ionomer cements to dentin--an in vitro study. |
p. 130 |
R Arora, SD Deshpande PMID:10635141An in vitro study was carried out on 40 periodontally involved, caries free human maxillary and mandibular molars to evaluate shear bond strength of resin- modified restorative glass-ionomer cements to dentin. Teeth were divided into four groups, Group I--Fuji II (Conventional glass ionomer) Group II (Fuji II LC), Group III (Vitremer), Group IV (Geristore). Shear bond strength was tested using a transaxial testing machine. Results showed that shear bond strength of all resin-modified restorative glass-ionomer cements was higher than conventional glass ionomer (Fuji II) tested. No statistical difference was found between Fuji II LC and Geristore. However, bond strength of Vitremer was lower than Fuji II LC and Geristore but higher than Fuji II. |

Crouzon disease--a case report. |
p. 134 |
A Sharma, N Dang, S Gupta PMID:10635142The present case of a ten year old boy with craniofacial dysostosis with the features of midfacial hypoplasia is a disease known as Crouzon disease. This disease is characterised by cranial deformities, facial malformation, eye changes and occasional other associated abnormalities. The aim of this case is to discuss the clinical, radiographic features and management of the problems. |
