Dental notation for primary teeth: a review and suggestion of a novel system.

BACKGROUND: Tooth designation systems are routinely used in dental practice, for identification of teeth, recording dental data and communication among dental professionals. There are various dental notations systems for the primary and permanent dentition. The most popular are the Zsigmondy-Palmer system, the Universal Numbering System, and the FDI system. Others includes the Victor Haderup system, the Woelfel system, and the MICAP system. The majority of dental notations are focused on permanent teeth and are modified for primary teeth, even though the latter erupt before the permanent dentition. CONCLUSION: Advantages and disadvantages of notations for primary dentition are discussed and compared to a new alphanumeric system for primary teeth which is considered simple and convenient.

An in vitro assessment of fluoride uptake by tooth enamel from four different fluoride dentifrices.

AIM: The aim of this study was to evaluate fluoride uptake by tooth enamel with four different fluoride dentifrices. STUDY DESIGN: Sixty human premolars extracted for orthodontic purpose were selected for the study. The teeth were covered with nail varnish leaving a window of 4 × 4 mm on the enamel surface of the buccal and lingual sides. The teeth were demineralised and were divided into four groups with 15 teeth in each group. The buccal window served as experimental and the lingual as control. The teeth were immersed in toothpaste slurry containing: sodium fluoride (Group A); sodium monofluorophosphate (Group B); stannous fluoride (Group C) and amine fluoride (Group D). The fluoride content in the etched superficial enamel layer in the windows was analysed using a fluoride ion-specific electrode. RESULTS: Within the parameters of this study, the uptake of fluoride was statistically significant in Group D (p < 0.05). The uptake of fluoride by tooth enamel in an increasing order was Group A < Group B < Group C < Group D. CONCLUSION: The study showed that enamel treated with amine fluoride had the highest fluoride uptake.

Efficacy of a probiotic and chlorhexidine mouth rinses: a short-term clinical study.

INTRODUCTION: Probiotic technology represents a breakthrough approach to maintaining oral health by utilizing natural beneficial bacteria commonly found in healthy mouths to provide a natural defense against those bacteria thought to be harmful to teeth and gums. However, data are still sparse on the probiotic action in the oral cavity. The review article on probiotics in children published by Twetman and Stecksen- Blicks in 2008 showed only one study of dental interest on probiotics in children. AIM AND OBJECTIVES: The present study evaluated clinically the efficacy of a probiotic and chlorhexidine mouth rinses on plaque and gingival accumulation in children. The trial design is a double-blind parallel group, 14 days comparative study between a probiotic mouth rinse and a chlorhexidine mouth rinse, which included 45 healthy children in the age group of 6-8 years. RESULTS: The Probiotic and Chlorhexidine groups had less plaque accumulations compared with the Control group at the end of 14 years (P < 0.001 and P < 0.001, respectively). But, unlike the plaque score, there was a significant difference in the Gingival Index between the Probiotic and the Chlorhexidine groups (P = 0.009), Probiotic group being better than the Chlorhexidine group (mean = 0.2300 and 0.6805, respectively). CONCLUSION: The Probiotic mouth rinse was found effective in reducing plaque accumulation and gingival inflammation. Therefore, probiotic mouth rinse obviously has a potential therapeutic value and further long-term study is recommended to determine its efficacy.

Double dens invaginatus in an impacted molariform supernumerary tooth: a unique case.

Dens invaginatus is a relatively rare developmental anomaly affecting usually the permanent maxillary lateral incisor. Various factors have been put forward regarding its pathogenesis. Involvement of crown/root has been reported as the coronal and radicular variety of dens invaginatus. One of the rarest variant is the Double dens invaginatus and only a few cases have been reported in the literature.This article focuses on a case of double dens invaginatus in an impacted maxillary anterior supernumerary tooth, the associated complications and its management.

Chair side simple caries activity test: Ora test.

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 [gamma = 0.913]. The Oratest is found to be a simple chair side, less time consuming and inexpensive caries activity test.

Dental caries prevalence among preschool children of Hubli: Dharwad city.

The prevalence of dental caries and treatment needs in the age group of 3-5 years was estimated among 1500 children of Hubli-Dharwad city. The attitude of mothers towards their children's oral health and its relation with caries prevalence was noted among 200 subjects. The prevalence of dental caries was 54.1%. The attitude of mothers towards children's oral health made a statistical difference in the mean dmft levels.

Prevalence of dental caries among 5-13-year-old children of Mangalore city.

A study of prevalence of dental caries was undertaken in 5-13-year-old children from Mangalore city. A total of 524 children were examined. The sample consisted of 193, 160, and 171 children in the 5-7, 8-10 and 11-13 years of age group, respectively. Dental caries was examined visually and observations were recorded. Silness and L phie plaque index, L phie and Silness gingival index were used to record the periodontal status. The prevalence of dental caries was highest in 5-7-year-age group compared to 8-10 years and 11-13 years age groups. The increasing prevalence of dental caries needs dental health programmes, which target the specific segments of the population.

Peripheral fibroma with calcification--a case report.

A female patient aged 10 years reported with an intra oral swelling on the labial aspect of 32 & 33, appearing to originate from the marginal gingiva & interdental papilla. The swelling was pedunculated, mobile, non-tender, firm in consistency with an irregular surface. The colour of the gingiva was normal with slight ulceration. The swelling was excised & diagnosed histopathologically as peripheral cementifying/ossifying fibroma.

Synthesis and antihyperlipaemic activity of some 2-aminomethyl-3-aryl-5,6,7,8-tetrahydrobenzo(b)/5,6-dimethylthieno++ +(2,3- d) -pyrimidin-4-ones.

A series of 2-aminomethyl-3-aryl-5,6,7,8-tetrahydrobenzo(b)/5,6-dimethylthieno (2,3-d) pyrimidin-4-ones (IX) were prepared by the displacement reaction between various amines and 2-chloromethyl-3-aryl-5,6, 7,8-tetrahydrobenzo(b)/5, 6-dimethylthieno(2, 3-d) pyrimidin-4-ones (VIII), which are obtained by the cyclization of corresponding chloroacetylamino derivatives (VII) under acidic condition. Compounds VII were obtained by the interaction of VI and chloroacetylchloride in glacial acetic acid. Compounds VIII were converted to corresponding 2-acetoxymethyl derivatives (X) with potassium acetate in glacial acetic acid. Selected compounds were screened for antihyperlipaemic activity in albino rats, whereby most of these compounds were found to be active. The serum cholesterol and triglyceride lowering activities exhibited by compounds 1 and 3 were found to be comparable to that of gemfibrozil. Compounds 1 and 3 were also found to be safe as indicated by their acute toxicity study.
