molecular identification and antibiotic resistant bacteria isolated from Primary Dentition infections
Australian Dental Journal, 2014Co-Authors: Juan Pablo Loyolarodriguez, Jose Obed Garciacortes, Rita Elizabeth Martinezmartinez, Nuria Patinomarin, Gabriel Alejandro Martinezcastanon, N V Zavalaalonso, Atsuo AmanoAbstract:BACKGROUND: Bacterial resistance to antibiotics is a health problem in many parts of the world. The aim of this study was to identify bacteria from dental infections and determine bacterial resistance to antibiotics used in dental care in the Primary Dentition. METHODS: This cross-sectional study comprised 60 children who presented for dental treatment for active dental infections in the Primary Dentition. Samples from dental infections were collected and bacteria were identified by polymerase chain reaction (PCR) assay. Bacterial resistance to antibiotics was determined by colony forming units on agar plates containing amoxicillin, clindamycin and amoxillicin-clavulanic acid (A-CA) tested at 8 μg/ml or 16 μg/ml. RESULTS: Clindamycin in both concentrations tested (8 μg/ml and 16 μg/ml) showed the highest bacterial resistance (85.9%), followed by amoxicillin (43.7%) and A-CA (12.0%). All comparisons among the three antibiotics used in the study exhibited statistical significance (p = <0.05) in both concentrations tested (8 μg/ml and 16 μg/ml), and under aerobic and anaerobic conditions. The most prevalent resistant species identified by PCR in Primary Dentition infections were: Streptococcus oralis and Prevotella intermedia (75.0%); Treponema denticola and Porphyromonas gingivalis (48.3%); Streptococcus mutans (45.0%); Campylobacter rectus; and Streptococcus salivarius (40%). CONCLUSIONS: This study demonstrated that A-CA exhibited the lowest bacterial resistance for clinical isolates in Primary Dentition infections.

Traumatic Dental Injuries in the Primary Dentition: a 15‐year bibliometric analysis of Dental Traumatology
Dental Traumatology, 2016Co-Authors: Paulo Floriani Kramer, Juan Eduardo Onetto, Marie Therese Flores, Tássia Silvana Borges, Carlos Alberto FeldensAbstract:AIM: To explore the profile of articles on traumatic dental injuries (TDI) in the Primary Dentition published in Dental Traumatology in the last 15 years using bibliometric analysis. METHODS: Three researchers read all titles and abstracts of articles published in Dental Traumatology between 2000 and 2014 (excluding editorials and letters) and selected all articles on TDI in the Primary Dentition. The articles were categorized according to year of publication, country in which the study was conducted, study design, and topics addressed. Divergences were resolved by consensus between the researchers. RESULTS: Among a total of 1257 articles published, 98 were initially excluded. Among the remaining 1159 articles, 152 (13.1%) focused on TDI in the Primary Dentition. The articles were conducted in 29 countries, with Brazil (38.8%) and Turkey (11.8%) accounting for the largest numbers. Cross-sectional studies (36.2%) and case report/case series (33.6%) were the most frequent study designs. Only two systematic reviews were published. The most commonly addressed topics were frequency/etiology/associated factors (36.8%), treatment (30.9%), and prognosis (19.7%). Among the articles addressing treatment, two-thirds were case reports or case series. The effects of TDI in Primary teeth on their permanent successors were addressed in 20.4% of the articles (31/152). CONCLUSIONS: The number of articles on TDI in the Primary Dentition has increased, but remains low. The evaluation of study designs and topics addressed identified gaps that could contribute to the development of new studies on TDI in the Primary Dentition, especially cohort studies that evaluate risk factors, prognosis, and treatment.

traumatic injuries in the Primary Dentition
Dental Traumatology, 2002Co-Authors: Marie Therese FloresAbstract:Abstract – As a support for the guidelines published in 2001, a review of the literature was carried out using the evidence-based approach in order to update the state of the art regarding epidemiology and treatment of traumatic dental injuries in the Primary Dentition. An online search in Medline, and a review of expert literature, lead to the conclusion that most luxation injuries heal spontaneously, and unless more conclusive evidence is available, conservative treatment of acute dental trauma for preschool children is suggested. Pain control, the dentist's ability to cope with the child's anxiety, and follow-up instructions in oral hygiene techniques will allow many Primary teeth that are currently lost at the time of injury to be saved.

Assessment of occlusal characteristics of the Primary Dentition: a cross-sectional study in Brazilian preschool children
Revista da Faculdade de Odontologia - UPF, 2016Co-Authors: Juliane Bervian, Paulo Floriani Kramer, Carlos Alberto Feldens, Larissa Corrêa Brusco PavinatoAbstract:Objective: The present study aimed to determine the occlusal characteristics and prevalence of malocclusion among Brazilianpreschool children. Subjects and method: A cross-sectional study was conducted with 1004 children aged 2-5 years enrolled in public preschools of the city of Canoas, RS, Brazil. A questionnaire was administered to guardians addressing demographic, socioeconomic, and behavioral characteristics of the children and their families. The clinical exam was performed by previously calibrated dentists and the characteristics of the Primary Dentition were verified according to set criteria. Data analysis was performed through the chi-square test. Results: Stability in the sagittal and transverse planes of the posterior region, and a variability of incisal relations in the Primary Dentition were verified. The findings show high prevalence of malocclusion (70.3%) and its association with age. Conclusion: Considering the high prevalence of malocclusion in Primary Dentition, implementing educational programs and prevention measures for preschool children is highlighted.

Risk factors for traumatic dental injuries in the Primary Dentition: concepts, interpretation, and evidence
Dental Traumatology, 2016Co-Authors: Carlos Alberto Feldens, Tássia Silvana Borges, Fabiana Vargas-ferreira, Paulo Floriani KramerAbstract:The purpose of this comprehensive review is to explore the main concepts related to quantification and interpretation of risk factors and investigate characteristics associated with traumatic dental injuries (TDI) in the Primary Dentition. Initially, the main concepts related to causality and risk factors were summarized, including how to measure, express, and compare risk as well as interpret statistical significance. Based on a structured search through PubMed, original research articles regarding TDI and associated factors in the Primary Dentition were then reviewed by two examiners. Studies with a sample size of at least 300 children aged between 0 and 6 years were summarized according to journal, country, study design, and type of statistical analysis. Variables associated with TDI in Primary teeth were identified from studies with multivariable analysis. Measures of effect size and P values were presented. Thirty-two studies were retrieved: most were cross-sectional in design and only 17 (53.1%) performed multivariable analysis. Most investigations did not find an association between gender and socioeconomic variables with TDI. Increased overjet was the only factor consistently identified as an associated factor. Behavioral characteristics have been recently investigated and suggested as potential risk factors for TDI in the Primary Dentition. In conclusion, increased overjet is undoubtedly associated with TDI in the Primary Dentition. As behavioral factors may be targeted by preventive strategies, their role on TDI occurrence should be clarified in future cohort studies. Clinicians should understand the terms and measures described in studies on risk factors to properly apply knowledge and benefit patients.
