For instance, if an unidentified decomposed body is found, testing the lead in the teeth could immediately help focus the investigation on a certain geographic area. That way, law enforcement can avoid wasting resources checking for missing persons in the wrong places.Read more

Evaluation of a parent-designed programme to support tooth brushing of infants and young children

Abstract ObjectivesThis study developed and tested an intervention to help parents establish a routine of brushing their young children's teeth twice a day. MethodsCommunity-based participatory research methods were used to engage parents in the design of the intervention to maximize its relevance and acceptability to others. Input was obtained by interviews and focus groups. The resulting intervention was four 90-min small-group sessions that provided educational information, direct instruction, practice and peer-to-peer problem-solving. A pre- to post-non-randomized design was used to evaluate the intervention's effect to increase or maintain parents' twice daily brushing. ResultsIntervention…Read more

The effect of chlorhexidine dentifrice or gel versus chlorhexidine mouthwash on plaque, gingivitis, bleeding and tooth discoloration: a systematic review

Abstract ObjectiveTo systematically review and evaluate the available scientific evidence on the effectiveness of chlorhexidine dentifrice or gel (CHX DF/gel) compared to chlorhexidine mouthwash (CHX MW) on plaque, bleeding, gingival inflammation and tooth discoloration scores. Material and methodsPubMed-MEDLINE, Cochrane-CENTRAL and EMBASE databases were searched to identify appropriate studies. ResultsIndependent screening of the 2256 unique titles and abstracts resulted in five publications that met the eligibility criteria. Considerable heterogeneity was found between the studies. Three of the five studies showed a positive effect on plaque scores in favour of the CHX MW. With respect…Read more

Comparison of effectiveness of abrasive and enzymatic action of whitening toothpastes in removal of extrinsic stains – a clinical trial

Abstract ObjectiveTo compare the effectiveness of abrasive component (perlite/calcium carbonate) and enzymatic component (papain and bromelain) of whitening toothpaste in removal of extrinsic stains. MethodsThis study is a randomized, triple blind and parallel group study in which 90 subjects aged 18–40 years were included. At baseline, stains scores were assessed by Macpherson's modification of Lobene Stain Index and subjects were randomly assigned to two groups with 45 subjects in each. Group 1 used whitening toothpaste with enzymatic action and group 2 with abrasive action. After 1 month, stain scores were assessed for the effectiveness of…Read more

The influence of educational level and oral hygiene behaviours on DMFT index and CPITN index in an adult Italian population: an epidemiological study

Abstract ObjectivesTo estimate the influence of educational level and oral hygiene behaviours on the prevalence and severity of dental caries and periodontal disease in an adult Italian population attending the Oral Hygiene department of a public Dental Clinic. MethodsDental caries was diagnosed according to the World Health Organization criteria. The DMFT index (decayed, missing, filled tooth) was used to record the dental caries' experience. The periodontal status was assessed using the community periodontal index of treatment needs (CPITN). Questionnaires on educational level and oral hygiene behaviours were also collected.
