Talon cusp affecting primary dentition in two siblings: a case report

The term talon cusp refers to a rare developmental dental anomaly characterized by a cusp-like structure projecting from the cingulum area or cement-enamel junction. This condition can occur in the maxillary and mandibular arches of the primary and permanent dentitions. The purpose of this paper is to report on the presence of talon cusps in the primary dentition of two southern Chinese siblings. The 4 years and 2 months old girl had a talon cusp on her maxillary right primary central incisor, while her 2 years and 9 months old brother had bilateral talon cusps on the maxillary primary central incisors. The presence of this rare dental anomaly in two siblings has scarcely been reported in the literature and this may provide further evidence of a hereditary etiology.Article Link: http://www.rjme.ro/RJME/resources/files/540113211213.pd

Morphometric analysis of the apical foramina in extracted human teeth

Background: The aim of the study was to analyse the morphology of the apical foramen in permanent maxillary and mandibular human teeth.Materials and methods: The anatomic parameters include shapes (rounded, oval, uneven, flat and semilunar) and location (centre, buccal/labial, lingual/palatal, mesial, and distal) of the apical foramina was evaluated. The shapes and locations of apical foramen were analysed based on tooth type (central incisor, lateral incisor, canine, premolars, and molars) arch type (maxillary and mandibular), and position (anterior and posterior). All the teeth were investigated for the apical foramina shape and location using a stereomicroscope at a magnification of 10×. Descriptive statistics performed using SPSS (Version 21.0, IBM, NY, USA) at p value less than 0.05.Results: The common shape of apical foramina was round (65%) and location was centre (32%). The frequency of deviation of apical was 68% in overall teeth. Apical foramina in maxillary anterior teeth showed more deviation while posterior teeth in mandibular teeth. The most common shape of apical foramina was round (65.1%) followed by (31%) and flat and semilunar shapes are very rare in studied subjects.Conclusions: The most frequent direction of deviation is the distal surface, followed by the mesial surface. The variation is more common in mandibular posterior teeth, while maxillary posteriors showed the least difference. The commonest shape of the apical foramen is of a round shape, followed by the oval. The oval shape of the apical foramen is most frequent with central incisors

Radiographic localization of supernumerary teeth in maxilla

This journal supplement is Special Issue: Abstracts of the 23rd Congress of the International Association of Paediatric Dentistry, 2011Poster Session P29 - Dental Trauma 4/TMJ/Xrays/Education: abstract no. P29-526BACKGROUND: Localization of supernumerary teeth is essential for diagnosis and treatment planning, and several techniques have been reported in the literature. Nevertheless, vertical tube shift (VTS) and horizontal tube shift (HTS) techniques are commonly used for localization of supernumerary teeth. AIM: This study sought to evaluate the reliability of two different localization techniques (VTS and HTS) for supernumerary teeth. DESIGN: Seventy five patients were randomly selected from the records of paediatric patients at the Prince Philip Dental Hospital. Only non-syndromic patients with single supernumerary teeth, and complete clinical and radiographic (PAN, AO, PA and CBCT) records were included. Ten examiners independently rated 75 pairs of radiographs for each technique. Descriptive statistics were computed using chi-squire teat and kappa statistics was employed to assess the intra- and inter- observer reliability. RESULTS: Data from 750 pairs were available for analysis. The overall sensitivity for VTS and HTS was 73% and 72.9% respectively with slight inter- and good intra- examiner reliability. Statistically significant differences were not evident between the two techniques for localizing supernumerary teeth. CONCLUSION: Based on the findings of this study, an approximate 27% failure rate was evident for both VTS and HTS techniques.link_to_OA_fulltextThe 23rd Congress of the International Association of Paediatric Dentistry, Athens, Greece, 15-18 June 2011.

Efficacy of licorice lollipops in reducing dental caries in a paediatric population: A systematic review

PubMed: 32238980Purpose: To assess the efficacy of licorice lollipops in reducing dental caries in children. Materials and Methods: A literature search was confined to the English language using MeSH terms congruent with PICO format in 'PubMed', 'Cochrane Library' and 'Ovid', covering the period from April 1967 to December 2017. Searches in Google Scholar, grey literature and hand search of cross-references were performed to find additional data. Suitable studies were selected based on the predefined inclusion and exclusion criteria. Quality analysis and risk of bias of the selected studies were performed using the Cochrane Collaboration's tool for risk of bias. Results: Overall 519 articles were retrieved, 516 (electronic databases) and 3 (Google scholar). 516 publications were excluded due to non-availability of abstracts, or because they were unrelated studies, narrative reviews, and systematic reviews as well as letters to editors. Only three studies were included for final analysis. Quality analysis of these three studies showed that only one was of high quality, whereas the other two were rated as low. Conclusion: Licorice lollipops showed a promising effect in reducing caries by decreasing Streptococcus mutans counts in the saliva. Further research using randomised controlled clinical trial (RCT) designs with large sample size are recommended. © 2020, Quintessence Publishing Co., Ltd.Majmaah University: R-1441-44The authors would like to thank the Principal, Narayana Dental College and Hospital, Nellore, Andhra Pradesh, P, India for support, as well as the Deanship of Scientific Research at Majmaah University for supporting this work under project No. R-1441-44

The effectiveness and ease of a one-step conditioning agent with conventional acid etch and priming in the placement of sealants: A 6-month follow-up

Objectives: The objective of the study was to evaluate the caries incidence of occlusal surfaces sealed using the two different techniques after 6 months and the ease of placement of sealant following the two techniques, for children and operator. Materials and Methods: Children between the age groups of 8–11 years and only mandibular molars were involved in the study; the techniques used for enamel preparation before sealant placement on the right and left side of the mandibular arch were randomized. On one side Adper™ SE plus and on the other side phosphoric acid etches together with Adper™ Single Bond 2 were used. Clinpro™ sealants were placed on both sides. The retention with these two techniques was compared after 6-month-based Color Coverage Caries system. The opinions of the children were taken on the two techniques that were used and recorded on individual questionnaires using Facial Grimace Scale and the operator by visual analog scale. Descriptive statistics carried out using SPSS (version 17.0). Results: Fifty-seven (95%) of the sixty children were available for the follow-up after 6 months. The retention of the acid-etch group was significantly superior (P = 0.00*) as was the caries preventive effect (P = 0.04*). Children felt that the placement of sealants was easier following enamel preparation with Adper™ SE Plus (P = 0.00*) and same as the operator. Conclusions: The regular acid etch with placement of sealant showed less caries occurrence on the occlusal surface after 6 months. Both the operator and children opined that acid-etch method for the placement of sealants is more comfortable
