A clinical assessment of the effectiveness of mouthwashes in comparison to toothbrushing in children. |
p. 38 |
U Sharma, RL Jain, A Pathak PMID:15491083The study compared the efficacy of unsupervised tooth-brushing done once a day before breakfast (phase 1), with twice daily mouthrinsing with the three different commercially available mouthwashes containing 0.2% sodium fluoride (phase 2), a combination of 0.03% triclosan and 0.05% sodium fluoride (phase 3), and 0.2% chlorhexidine (phase 4) in 20 children aged 13-14 year, in reducing dental plaque formation. The results showed that there was a statistically significant difference in plaque reduction between phases 1 & 2; 1 & 3; 2 & 4 and 3 & 4. The mandibular arch harboured more plaque than the maxillary arch in phase 1 (p<0.05). Irrespective of the mouthwash used, the lingual/palatal surfaces had less plaque than the facial surfaces (p<0.05). The mean cumulative plaque scores of the mandibular lingual surfaces was more in comparison to the maxillary palatal surfaces in phases 1, 2 and 3 (p<0.05). It was therefore, concluded that 0.2% chlorhexidine was comparable to tooth brushing done once a day, before breakfast. |

Inverted central incisor--a case report. |
p. 45 |
ND Shashikiran, G Dhananjaya, VV Subba Reddy PMID:15491084An unusual case of inverted central incisor in a nine year old girl is reported here. The case was diagnosed as an infected dentigerous cyst.

Prevalence of DMFT and fluorosis in the students of Dayer city (Iran). |
p. 49 |
Gh H Ramezani, N Valaei, H Eikani PMID:15491085The survey was performed using the cross-sectional method on 506 students selected using multi-stage random sampling. The fluorosis level according to Deans classification and DMFT with its standard method were surveyed. The water fluoride level was estimated in 6 town sources twice, using Alizarin chemical method. The fluorosis and DMFT prevalence in the samples was determined. A total number of 506 students (55.6% boys and 44.4% girls) aged 13 +/- 3 years were examined. The water fluoride level was 2.43 +/- 0.23 ppm and in all the samples, which was more than normal. 19.9% of the subjects being surveyed were healthy 43.6% had mild, 25% moderate and 11.5% had severe fluorosis. Severe fluorosis was found in 65.8% of girls and 34.2% of boys (p < 0.05). The mean DMFT value was 1.8 +/- 1.73 and was higher in girls in comparison with boys (p < 0.05). |

Reattachment of fractured fragments of maxillary central incisors--report of a case. |
p. 54 |
G Lehl, R Luthra PMID:15491086Reattachment of the original tooth fragment to the fractured tooth helps in maintaining the tooth's colour, wear resistance, morphology and translucency in the restoration. This paper describes the reattachment of fractured fragments using metallic post and core in case of a 12 year old patients who suffered a complicated facture of maxillary central incisors. |

Comparative evaluation of glass ionomer and resin based fissure sealant using noninvasive and invasive techniques--a SEM and microleakage study. |
p. 56 |
GP Herle, T Joseph, B Varma, M Jayanthi PMID:15491087The efficacy of using invasive and non-invasive techniques was assessed by Scanning electron microscopy, and by microleakage of Glass ionomer (GC VII, Fuji) and Resin based sealant (Helioseal-F, Ivoclar Vivadent). 100 young premolars were used for this study, and they were divided into four groups: Group I: non-invasive technique GC VII, Group II: Invasive GC VII, Group III: Non-Invasive Helioseal-F, Group IV: Invasive, Helioseal-F. 5 teeth from each group were evaluated under SEM. It was seen that the flow and adaptation of GC VII was slightly better than Helioseal F, and the invasive technique provided the best flow and adaptation. For microleakage analysis 5% methylene blue was used. It was seen that minimal microleakage was seen in Group IV (P<0.01). Considering the recent controversies using resin based sealants, it can be said that GC VII can be a viable alternative for pit and fissure sealants. |

Congenital granular cell lesion "congenital epulis"--report of a case. |
p. 63 |
JK Dash, PK Sahoo, SN Das PMID:15491088Congenital granular cell lesion (CGCL) or "congenital epulis" is a rare lesion of newborn also known as Neuman's Tumor, which is benign in nature, mostly occurs as a single tumour but rarely as multiple. The histogenesis and natural clinical history of the lesion remains obscure. Even with the advent of modem histopathological techniques, it has not been possible to depict specific cellular features unique to this lesion. This lesion arises from mucosa of gingiva either from maxillary or mandibular alveolar ridge. The appearance of the lesion is most common in maxillary alveolar ridge than mandibular with predominance in females than in the males. The present report describes a case of congenital granular cell lesion (CGCL) in the incisor region of mandibular alveolar ridge. This lesion was causing feeding problem and was excised under local anaesthesia. |

Comparative evaluation of clinical efficacy of gallium and amalgam alloys in primary molars. |
p. 68 |
R Singh, S Tandon, M Rakhee PMID:15491089The present study was conducted to compare the clinical efficacy (marginal integrity and bulk fracture) of two alloys--Galloy (gallium based) and Aristaloy (amalgam based) in primary molars. 90 primary molars with initial caries formation were selected. 45 were restored with Galloy and 45 with Aristaloy in Class I and II preparations. They were evaluated at two-month intervals for 6 months. The results showed that Galloy performed at par with Aristaloy with regards to marginal integrity and bulk fracture. Hence Galloy can be considered as an interesting substitute in Pedodontic practice. |

Leach out of inorganic and trace elements at the time of etching. |
p. 76 |
S Sarkar, P Roychoudhary PMID:15491091The enamel is the hardest biological structure made up of inorganic ions, organic substances, trace elements and water and it covers the coronal part of dentin. Acid etching causes leaching out of inorganic and trace elements from the enamel surface. In the present study leach out pattern of 11 elements from the enamel surface during etching was studied. |

Folic acid and phenytoin induced gingival overgrowth--is there a preventive effect. |
p. 82 |
VN Prasad, HS Chawla, A Goyal, K Gauba, P Singhi PMID:15491092The role of folic acid (5mg/day) in combination with oral hygiene measures (group II) vis-a-vis oral hygiene measures alone (group I) in prevention of phenytoin-induced gingival overgrowth was investigated in a one-year follow-up study on sixty, 8-13-year-old epileptic children receiving phenytoin. The allocation of the children to the two groups was done alternately. In these children, at baseline, plaque (Silness & Löe), gingivitis (Löe & Silness) and probing depths of gingival sulcus were recorded. These parameters were re-evaluated at 3-monthly intervals when gingival overgrowth was also recorded (Modified Harris & Ewalt Index). It was seen that, after a period of one year, gingival overgrowth occurred in 60 and 50 percent children of groups I & II respectively and its development, too, was delayed in group II. More cases (93 percent) in group II exhibited minimal overgrowth as against 78 percent in group I. The study concluded that systemic folic acid prescribed along with phenytoin delays the onset and reduces the incidence and severity of gingival overgrowth induced by phenytoin. |
