Dental caries and associated factors in 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India.

OBJECTIVES: The aims of the present study were to describe the dental health status of 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India, and to identify sociodemographic factors, oral health behaviours, attitudes and knowledge related to dental caries experience. METHODS: The study took the form of a cross-sectional survey of 838 children in upper primary schools. A two-stage cluster sampling technique was used. Dental caries was measured using World Health Organization criteria. Sociodemographic factors, oral health behaviours, attitudes and knowledge were assessed by a self-administered questionnaire. RESULTS: The prevalence of dental caries in the permanent dentition was 27%. The mean number of decayed, missing and filled teeth was 0.5 (SD=0.9). The decayed component (D) constituted 91% of the total number of decayed, missing and filled teeth (DMFT). Multiple logistic regression analysis showed that children had a higher risk of having dental caries if they lived in urban area [OR=1.5, 95% confidence interval (CI)=1.1-2.1], had visited a dentist (OR=1.6, 95% CI=1.2-2.2), did not use a toothbrush (OR=1.9, 95% CI=1.2-2.9), consumed sweets (OR=1.4, 95% CI=1.0-1.9) or performed poorly in school (OR=1.7, 95% CI=1.0-2.3). CONCLUSIONS: The prevalence of caries in this sample of 12-year-old schoolchildren was low compared to that in other developing countries. The present study indicated that urban living conditions were associated with more dental caries. Since urbanization is rapid in India, oral health promotion at the present time would be valuable to prevent increased caries prevalence.

Incontinentia pigmentii acromians with seizure disorder: a case report.

Incontinentia pigmentii acromians (IPA) is a bizarre, irregularly shaped leukoderma of the trunk and extremities, characterized by marble cake-like whorls or streaks of hypopigmentation whose distribution can be unilateral or bilateral. Mode of inheritance is most consistent with an autosomal dominant type and in majority of the cases, one or more anomalies are present involving dermatological, dental and ocular disorders. A case of a female child, aged 2 1/2 yrs, referred from Pediatric neurology department, Medical College, Trivandrum with Incontinentia pigmentii acromians and seizure disorder is reported. Hamartomatous dental cusps and single maxillary central incisors have been associated with Incontinentia pigmentii acromians. A case of Incontinentia pigmentii acromians with hypoplastic teeth and tongue abnormalities is presented.

Caries prevalence and its relation to socio-economic status and oral hygiene practices in 600 pre-school children of Kerala-India.

This Study was undertaken to determine the caries status of pre-school children in Ulloor Panchayat of Trivandrum, Kerala and to determine the relation if any, between their caries and socio-economic status and oral practices. 200 children each from the low, middle arid higher socio-economic group were visually examined for caries by the same examiner in natural daylight. Caries was recorded according to the WHO criteria. Information regarding the childrens' oral hygiene practices were obtained through structured questionnaires to the care takers of the children. Computer analysis of the data collected showed that 43% of the study sample were caries free. Socio-economic level was found to have a negative association with caries status. The mode of tooth brushing was found to be significantly related to caries severity while the frequency of tooth brushing was found to have no association with caries prevalence and severity.

Comparison of sealing ability of three different root canal sealers--an in vitro study.

The 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.

Doomed angels--a case report.

A three year old female child was brought to the Department of Pedodontics, Dental College, Thiruvananthapuram with a greyish white papillomatous lesion involving a large area on the buccal mucosa. VDRL was positive for the little girl as well as her father and was positive in low concentrations for her one-month-old sister as well as her mother.

Effect of 4-META adhesive on bond strength and marginal seal of amalgam restorations and repairs--an in vitro study.

Amalgam remains unchallenged as a posterior restorative material. But its inability to bond to the teeth leads to some amount of microleakage at the restoration-tooth interface with associated problems such as post operative sensitivity, pulpal complications etc. Also a broken amalgam restoration requires replacement which will further weaken the tooth structure. Recently, 4-META has been introduced which can graft amalgam and composite to enamel, dentin and old amalgam restorations. In this study, the bonding and marginal sealing abilities of 4-META was assessed both at the tooth-amalgam interface and old amalgam fresh amalgam interface.

Surface treatment of enamel with laser--a potential alternative for acid etching--an in vitro study.

An in-vitro study was carried out on 80 human premolars to study the use of Nd:YAG laser as a potential alternative for acid etching in the surface treatment of enamel prior to sealant application. The determination of bond strength using Universal Testing Machine, Model 1011 and marginal leakage using the spectrophotometric dye recovery method showed no statistically significant difference between the groups with laser and acid surface treatments. But, there was a significantly lower bond strength and increased dye penetration in the group with no surface treatment. Scanning electron microscopic study of the interface between sealant and enamel surface of the acid and laser treated specimens was also carried out.
