Management of a case with bilateral talon cusp in primary dentition

PubMed ID: 17367038The talon cusp is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case and should be as conservative as possible. The purpose of this report was to present the case of bilateral talon cusp in primary maxillary central incisors that was successfully managed with conservative therapy

Clinical Performance of Fiber-Reinforced Nanofilled Resin Composite in Extensively Carious Posterior Teeth of Children: 30-Month Evaluation

WOS: 000335092900001PubMed ID: 24579274Objective: To evaluate the 30-month clinical performance of a nanofilled-resin composite with or without glass-fiber layering in restorations of large cavities in posterior teeth of children. Study Design: A total of 71 restorations were placed in permanent molar teeth of 47 children (mean age 10.9 years) with (FRC; n=35) or without (RC; n=36) fiber layering. One operator placed all restorations. Restorations were evaluated according to the USPHS modified-Ryge criteria at baseline, 6, 12, 18, 24, and 30 months. The data were analyzed using Fisher's exact and chi-square tests and outcomes were compared using the Cochran-Q test (p<0.05). Results: The 30-month survival rates of the restorations were 97% and 97.1% in the RC and FRC groups, respectively. Nanofilled-resin restorations with or without glass fiber-layering showed similarly high clinical performance. No differences were detected between the evaluated criteria when comparing baseline with any of the evaluation periods (p<0.05). After 30 months there were no secondary caries, change in anatomical form or postoperative sensitivity. Only minor changes for marginal adaptation, marginal discoloration, color match and surface texture were observed. Conclusion: It was concluded that nanofilled-resin composite applied with or without glass-fiber layering showed similar and good results in large cavities of posterior permanent teeth in children over a 30-month period

Microbiological evaluation and antibiotic susceptibility of dental unit water systems in general dental practice.

PubMed ID: 18205653OBJECTIVE: The microbial quality of water in a dental unit water systems (DUWS) is of considerable importance because patients and dental staff are regularly exposed to water and aerosol generated from the dental units. The objective of this study was to evaluate the 20 DUWS in general dental practices and to determine the antibiotic susceptibility of the colonizing bacteria. METHODS: Three water and one biofilm samples from each DUWS were investigated for total viable count (TVC), oral streptococci, Pseudomonas spp., Enterobacteria, Candida albicans and Legionella pneumophila. RESULTS: A total of 44 morphologically different colonies were obtained from water samples and 20 types of colonies (45.5%) could be identified using API test strips. The mean TVC values were 4.36 log CFU ml(-1) for source waters, 4.95 log CFU ml(-1) for 3-in-1 syringe samples, 4.91 log CFU ml(-1) for air rotor samples and 3.66 log CFU cm(-2) for biofilm samples. Susceptibilities of the isolates were tested against piperacillin, ampicillin, ceftazidime, meropenem, gentamicin, tetracycline, ofloxacin and chloramphenicol by using microdilution method according to NCCLS. The meropenem and ofloxacin have shown the broadest spectrum against to the tested isolates. CONCLUSION: The study emphasizes the need for effective mechanisms to reduce the microbial contamination in DUWS, and highlights the risk for cross-infection in general dental practice

Dysosteosclerosis: A case with unique dental findings and SEM evaluation of a hypoplastic tooth

PubMed ID: 10551137A ten-year-old boy, who had the typical dental findings of dysosteosclerosis such as yellowish, hypoplastic teeth, retarded eruption, which upon eruption, decayed rapidly, is presented. To date this is the first known case reported with a congenital absence of the first permanent molars. Furthermore, SEM evaluation of the enamel and dentin was performed on a tooth from a patient with dysosteosclerosis for the first time. These studies showed weak ultrastructural compositions due to irregular calcification

Efficacy of propolis as an intracanal medicament against Enterococcus faecalis

PubMed ID: 17004565This study sought to compare the antibacterial efficacy of three commonly used intracanal medicaments with propolis against Enterococcus faecalis. This study utilized 180 freshly extracted single-rooted intact human permanent teeth with a single root canal. After root canal preparations and sterilization, canals were contaminated with E faecalis and incubated at 37°C (±1.0°C) for seven days. The teeth were divided randomly into six groups. To determine bacterial growth on blood agar, microbiological samples were carried out with sterile paper points to evaluate results at 48 hours and at ten days. All data were analyzed statistically with t-test, Mann Whitney, Kruskal Wallis, and one-way ANOVA tests. This study revealed that propolis had good in vitro antibacterial activity against E faecalis in the root canals, suggesting that it could be used as an alternative intracanal medicament

Kabuki syndrome with additional dental findings: A case report

PubMed ID: 18647516Kabuki Syndrome (KS) is a multiple congenital anomalies/mental retardation syndrome of unknown etiology. It is characterized by a dysmorphic face, postnatal growth retardation, skeletal abnormalities, mental retardation, and unusual dermatoglyphic patterns. The characteristic dental findings include hypodontia, microdontia, absence of upper lateral and lower central incisors and upper molars, abnormal tooth shape, widely spaced teeth, ectopic upper molars and malocclusion. The purpose of this report is to describe common and additional dental findings and dental treatment of an 11-year old female patient with KS. This case report emphasises the importance of oral and dental manifestations for diagnosis
