Loss of space and changes in the dental arch after premature loss of the lower primary molar: A longitudinal study
Padma Kumari B, Retna Kumari N
April-June 2006, 24(2):90-96
DOI:10.4103/0970-4388.26023  PMID:16823234
The purpose of the study was to evaluate the space changes, dental arch width, arch length and arch perimeter, after the unilateral extraction of lower first primary molar in the mixed dentition period. A longitudinal study was conducted among forty children in the age group of 6-9 years, who reported for extraction of lower first primary molar in the department of Pedodontics, Govt. Dental College, Trivandrum. Study models were made from alginate impression taken before extraction and after extraction at the periodical intervals of two months, four months, six months and eight months. The mesiodistal width of lower first primary molar of the non-extracted side was taken as the control. The results of the study showed statistically significant space loss in the extraction side ( P value <0.01) and no significant space loss in the control side ( P value > 0.05). The rate of loss was greatest in the first four months. The arch width, arch length and arch perimeter had no significant change from initial to eight months follow up. The present study challenges the use of a space maintenance under the circumstances of premature loss of mandibular primary molar for preventing space loss.

Surgical and orthodontic treatment of an impacted permanent central incisor: A case report
NR Thosar, P Vibhute
April-June 2006, 24(2):100-103
DOI:10.4103/0970-4388.26025  PMID:16823236
Although impaction of a permanent tooth is rarely diagnosed during the mixed dentition period, an impacted central incisor is usually diagnosed accurately when there is delay in the eruption of tooth. In this article, the impacted incisor was moved into it's proper position with surgical exposure and orthodontic traction, after which it showed good stability.

Epidemiological and etiological study of oral submucous fibrosis among gutkha chewers of Patna, Bihar, India
Mohammad Sami Ahmad, SA Ali, AS Ali, KK Chaubey
April-June 2006, 24(2):84-89
DOI:10.4103/0970-4388.26022  PMID:16823233
An etiological and epidemiological study of oral submucous fibrosis (OSMF) has been done in Patna, Bihar. Total 157 cases of OSMF and 135 control subjects were selected for study in the period of 2002-2004. It was observed that Male: Female ratio was 2.7: 1. The youngest case of OSMF was 11 year old and the oldest one was 54 years of age. Maximum number of cases were belonging to 21-40 years of age and they were belonging to low or middle socioeconomic class. Most of the OSMF cases used heavy spices and chillies, where as control mild spices and chillies. Gutkha was the most commonly used by the OSMF cases only 3 per cent did not use any gutkha or other areca nut product where as 80 per cent control did not have any chewing habit. The OSMF cases used gutkha and other products 2-10 pouches per day and kept in the mouth for 2-10 minutes and they were using since 2-4 years. Most of the OSMF cases kept gutkha in the buccal vestibule or they chewed and swallowed it, only a small number of patients chewed and spitted it out. It was also observed that OSMF developed on one side of the buccal vestibule where they kept the chew and other side was normal.

Is tongue thrust that develops during orthodontic treatment an unrecognized potential road block?
HS Chawla, Sanjay Suri, A Utreja
April-June 2006, 24(2):80-83
DOI:10.4103/0970-4388.26021  PMID:16823232
The role of tongue thrust has often been suspected, long debated and largely dispelled as a primary etiological factor of malocclusion. However, tongue thrust may contribute to poor occlusal intercuspation both during and after treatment. A tongue thrust may also develop during orthodontic mechanotherapy as a result of the transient creation of intra and interarch spaces and this little recognized phenomenon was found to occur in many randomly followed cases. In many instances, this seemingly adaptive and secondary response of the tongue posture and function may persist and thereafter impede the resolution of intra and interarch problems.

Chair side simple caries activity test: Ora test
Bhasin S, Sudha P, Anegundi R T
April-June 2006, 24(2):76-79
DOI:10.4103/0970-4388.26020  PMID:16823231
Oratest, a caries activity test was performed on 48 school going children of Mangalore city to estimate efficacy of the test. High statistical significance was found when the means of control and test group were compared [γ = 0.913]. The Oratest is found to be a simple chair side, less time consuming and inexpensive caries activity test.

Effect of enamel preparations on fracture resistance of composite resin buildup of fractures involving dentine in anterior bovine teeth: An in vitro study
K Gandhi, B Nandlal
April-June 2006, 24(2):69-75
DOI:10.4103/0970-4388.26019  PMID:16823230
Sixty bovine teeth with simulated mesio-incisal angle fracture were randomly and equally divided in one untreated (control) group and three experimental groups (Bevel, Chamfer and newly introduced Stair-step Chamfer preparation group) to evaluate the effect of enamel preparations on the fracture resistance of composite resin. Post restoration, fracture mechanics approach was used to quantify the failure of composite resins in testing the samples in Instron testing machine. Mean peak failure load (Newton) of composite amongst experimental groups was observed in the order; Chamfer (326.09 + 72.73), Stair-step chamfer (315.21 + 81.77) and Bevel (253.83 + 67.38). Results of the One-Way ANOVA revealed significant difference in the mean peak failure load values of the four different groups. ( P < 0.001) Scheffe's Post-Hoc comparison test (Subset for alpha = 0.05) revealed that there was no significant difference in the mean peak failure load values of the bevel, stair-step chamfer and chamfer preparation when considered together, but the mean peak values of control group (605.22 + 48.96) were observed significantly higher. Failure mode evaluation revealed, majority of failures occurred as cohesive and mixed type for all the experimental groups. Adhesive type failure was observed maximum (33%) in the bevel group. Stair-step chamfer preparation showed greatest potential for application and use as it no only demonstrated comparable values to Chamfer preparation ['t' value (0.39) ( P > 0.05)] but also involved sacrificing less amount of tooth structure adjacent to fractured edge.

Genetic sensitivity to the bitter taste of 6-n propylthiouracil: A new risk determinant for dental caries in children
S Rupesh, Ullal Anand Nayak
April-June 2006, 24(2):63-68
DOI:10.4103/0970-4388.26018  PMID:16823229
The aims of the present study were to contrast the prevalence of dental caries in children with different genetic sensitivity levels to the bitter taste of 6-n-propylthiouracil (PROP) and to determine the taste quality and taste intensity preferences of food products among the taster and nontaster groups. Overall caries experience (dmfs/DMFS) was significantly higher for nontasters than tasters. Caries experience on the available surfaces (dfs/DFS) was found to be significantly higher in nontasters than in medium tasters and in medium tasters than in supertasters (r=-0.41, P <0.001). Majority of the nontasters were sweet likers and preferred strong tasting food products, while majority of the supertasters were sweet dislikers and preferred weak tastes. There was a significant increase in the overall caries experience in the population, as the genetic ability to detect PROP taste decreased ( P <0.001). After all associated factors (age, gender, race, number of teeth and OHI-S) were controlled; multiple linear regression analyses revealed that taste was the only variable significantly related to overall caries experience.

Congenital epulis - congenital granular cell lesion: A case report
Kannan S Karthiga, Rajesh R
April-June 2006, 24(2):104-106
DOI:10.4103/0970-4388.26026  PMID:16823237
Neumann first described congenital epulis (CE) of newborn in 1871. CE occurs at birth and has a striking predilection for females. It is most frequently located on the anterior maxillary alveolar ridge. CE clinically appears as a pedunculated protuberant mass. In cases with large lesions mechanical oral and nasal obstruction can impair fetal deglutition and neonatal respiratory efforts resulting in polyhydramnios prenatally or respiratory impairment postnatally. Histologically CE shows characteristic large cells with granular cytoplasm and spindle cells resembling fibroblasts. The exact histiogenesis is still uncertain, various theories of origin are epithelial, undifferentiated mesenchymal cells, pericytes, fibroblast, smooth muscle cells and nerve related cells. A newborn female child with CE in the maxillary alveolar ridge reported to our institution is presented with investigation, management and follow-up.
