Pyramidal molar roots in primary and permanent dentition along with non syndromic oligodontia in a 11 year old boy.

Primary and permanent molars are usually multi rooted. At times we can encounter cases with a single root, called pyramidal root. Oligodontia is defined as the developmental absence of six teeth or more, excluding third molars. It can be isolated (Oligodontia-I) or as a part of a syndrome (Oligodontia-S) such as in ectodermal dysplasia. The present report describes a case of single-rooted primary and permanent molars associated with oligodontia in an 11 year old boy with no apparent systemic complications.

Management of three fused primary teeth.

Fusion is a dental anomaly in which two dental germs have developed separately and then become united. It is often confused with germination, unless until carefully evaluated clinically and radiographically. This paper describes a case of a six year old boy who presented with pain and swelling in right lower back tooth region. Intra oral examination revealed three fused primary teeth, which were confirmed radiographically. Radiographs also revealed missing permanent tooth buds associated with them. Since all the fused teeth were pulpally involved they were managed by pulpectomy. The incidence, prevalence, complications and treatment modalities are also discussed in this case report.

Chocolate mouth rinse: Effect on plaque accumulation and mutans streptococci counts when used by children.

Background: Glucosyltransferases (GTF) play an important role in the adherence of bacteria to acquired pellicle. Cocoa bean husk extract (CBHE) has been shown to possess anti-glucosyltransferase and antibacterial activity. Aim: This study aimed to evaluate the effect of CBHE on plaque accumulation and mutans streptococcus count when used as a mouth rinse by children. Materials and Methods: Scaling of the teeth of the selected children was done and the children were instructed to refrain from their routine oral hygiene practices till the morning of the fourth day; they were instead given a placebo mouth rinse for use during this period. On the fourth day, saliva was collected from each subject for microbiological analysis and plaque was disclosed and scored using the modified Quigley and Hein plaque index; later, the teeth were cleaned. After 1 week, scaling of the subjects was done and they were given CBHE mouth rinse to rinse their mouth, following the above protocol. The data was statistically analyzed using Wilcoxon's signed rank test. Results: There was a 20.9% decrease in mutans streptococci counts and a 49.6% decrease in plaque scores in the CBHE group as compared to the placebo group, which was highly significant (P value Conclusion: CBHE is highly effective in reducing mutans streptococci counts and plaque deposition when used as a mouth rinse by children.
