Objective: to compare the image quality obtained by six cameras used for dental documentation, including four DSLR cameras and two smartphones with different sensor size. Methods: the equipment determined the groups: APSCcan18-55 ­ Sensor APS-C Canon (EOS T5i) + 18-55 mm lens; APSCcan100 ­ Sensor APS-C Canon (EOS T5i) + 100 mm macro lens; APSCnik18-55 ­ Sensor APS-C Nikon (D5100) + 18-55 mm lens; APSCnik100 ­ Sensor APS-C Nikon (D5100) + 100 mm macro lens; ip1/3" ­ iPhone with 1/3-inch sensor; ga1/2.6"- Galaxy with 1/2.6-inch sensor. Two set of images -"dental documentation" and "small objects"- were obtained. The photographs were evaluated by three groups: US, undergraduate students; DS, dentists; and DP, dentists with photography experience. Scores between 0 and 10 were assigned. The results were compared by RM Anova and Tukey (α = 0.05). Results: the highest overall scores were obtained with APSCnik100 (8.5). For "dental documentation", APSCcan18-55 and APSCnik18-55 showed the lowest values, even compared to ga1/2.6" (for US, DS and DP evaluators) and ip1/3" (for US evaluators). For "small objects", DSLRs resulted in higher mean values compared to smartphones for US and DS. Conclusions: DSLR cameras with 18-55 mm lens and no circular flash should not be used for documentation photographs. DSLR cameras, regardless of lens, are superior to smartphones for small objects photographs. (AU)

Developmental dental anomalies and their potential role in establishing identity in post-mortem cases: a review.

Teeth may provide useful forensic evidence owing to features like uniqueness, stability and comparability. Moreover, the human dentition is heterodont, i.e. all the teeth have different morphology - incisors, canines, premolars and molars. There are sometimes deviations from normal morphology, such as the presence of extra teeth, variation in their shape and size eg the presence of an extra cusp, fractured crown/root, Carabelli's cusp, peg laterals, transpositions, fusion, etc. These differences can help forensic personnel identify bodies, especially where other methods of identification like facial features, fingerprints or DNA typing cannot yield satisfactory results as in cases of badly decomposed bodies, burnt remains, mass disasters, etc. Identification from dentition is based on the direct comparison of post-mortem dental profiles with ante-mortem dental records of the deceased. This article aims to review these developmental and morphological dental traits and their role in post-mortem identification.

Simple Approaches for Establishing an Evidence-Based Dental Practice.

Constructing an evidence-based dental practice requires leadership, commitment, technology support, and time, as well as skill practice in searching, appraising, and organizing evidence. In mastering the skills of evidence-based dentistry, clinicians can implement high-quality science into practice through a variety of opportunities including the development of clinical care guidelines, procedural technique protocols, and electronic dental record auto-note templates, as well as treatment planning, care prioritization, and case presentation. The benefits of building an evidence-based dental practice are many, including improvements in patient care and satisfaction, increased treatment predictability and confidence in care approaches, as well as potential cost savings.

Electronic clinical dental records: unintended consequences.

Record keeping is an essential component of delivering safe and appropriate care. In an ever increasing climate of litigation and complaints contemporaneous record keeping has assumed increasing importance, but is time consuming to do well and cover the aspects of care necessary. Practitioners have started using templates and copy and paste notes which, whilst useful, have their limitations and create problems of their own.

The Average Annual Percent Change Analyzes of Preventive Dental Care in the Slovak Republic, 2014-2016

Objective: To analyse of the average annual percent change (AAPC) of registered dental patients, patients with preventive dental care and patients requiring dental treatment in the period of 2014-2016 in the Slovak Republic. Material and Methods: Data from registered dental patients (n=14,736,888), patients with preventive dental care (n=8,212,441) and patients requiring dental treatment (n=5,262,323) in the period of 2014-2016 were obtained from the Statistical Office of the Slovak Republic; 28,211,652 dental patients were analysed. The Theil-Sen estimator of trend line based on median and its significance was tested by nonparametric Wilcoxon test using statistical software R package. Results: The significant decrease (-4.11%) of the AAPC rates of registered dental patient (p<0.05) during the entire period (2014-2016) can be observed in age subcategory 15-18 years, while in age subcategory 19+ years the nonsignificant increase (1.08%) of the AAPC rate of registered dental patients in the same period was achieved. In the period of 2014-2016, the highest AAPC rate of patients with preventive dental care with the significant decrease was found in age subcategory 6-14 years (-17.19%; p<0.001). The AAPC rate of patients requiring dental treatment proved the significant negative values in age subcategory 0-5 years (-7.26%; p<0.01), in age subcategory 6-14 years (-9.33%; p<0.001), in age subcategory 15-18 years (-8.81%; p<0.01). Conclusion: The highest decrease AAPC rate of registered dental patients was observed in age subcategory 15-18 years. The statistical significant decrease AAPC rate of patients with preventive dental care was found in children ≤ 18 years. In patients requiring dental treatment (≤ 18 y.) was observed decrease AAPC rate.

The use of tools to support oral lesion description in oral medicine referrals.

Poor description of oral lesions jeopardize the prioritization of appointments in Oral Medicine. The present study investigated whether the use of support tools changes the quality of descriptions focusing on health care prioritization. Two oral lesions (A and B) were described by 64 dental students and 48 dentists using three methods: (a) without support tools (free); (b) using the oral examination form from the Specialties Manual in Oral Health/Brazilian Ministry of Health (SMOH form); and (c) using the OralDESC guideline. The descriptions were compared with a gold standard and percentage of agreement was analyzed by the Kruskal-Wallis and Dunn's tests (p<0.05). Descriptions with the OralDESC presented higher information quality. Considering items essential for prioritization, the OralDESC demonstrated better performance for lesion A; for lesion B, free descriptions and descriptions using the OralDESC were of higher quality than those using SMOH form. Therefore, the OralDESC offered greater support for the description of oral lesions for health care prioritization in Oral Medicine.

Inaccurate Dental Charting in an Audit of 1128 General Dental Practice Records.

Fourteen dentists at different practices in the UK assessed the dental charts of 1128 patients who were new to the dentist but not new to the practice; 44% of the dental charts were found to be inaccurate. Inaccuracy of the individual practice-based charts ranged between 16% for the best performing practices to 83% for the worst: 5% of dental charts had too many teeth charted and 5% had too few teeth charted; 13% of charts had missed amalgam restorations and 18% had missed tooth-coloured restorations; 5% of charts had amalgam restorations recorded but with the surfaces incorrect (eg an MO restoration charted but a DO restoration actually present); 9% of charts had tooth-coloured restoration surfaces incorrectly recorded. For 7.5% of charts, amalgams were charted but not actually present. Other inaccuracies were also noted. The authors reinforce the requirements of the GDC, the advice of defence organizations, and the forensic importance of accurate dental charts. Clinical relevance: Dental charting forms part of the patient's dental records, and the GDC requires dentists to maintain complete and accurate dental records.

Attributes of the complete dental record: a Delphi approach to standards.

BACKGROUND: Adherence to the Dental Board of Australia Guidelines on dental records is not universal and remediation of deficient practise requires clarity in the practical application of standards. The aim of this research is to clarify practical requirements of dental record keeping in New South Wales. METHODS: Seventeen experts were invited to participate in an electronically administered series of Delphi questionnaires. Concepts were refined until consensus was reached. RESULTS: Two rounds were required to achieve a satisfactory level of consensus (>80%). A high level of consensus was obtained across the two rounds, with 72% and 86% agreement on propositions in the first and second rounds, respectively. Consensus criteria were established in 14 domains to establish attributes of the complete dental record (ACDR). CONCLUSIONS: The ACDR may supplement existing national guidelines and are likely to be useful in a remediation context in which clear, unambiguous expectations for conduct are paramount.

Improving the quality of endodontic record keeping through clinical audit.

Introduction Record keeping is an essential part of day-to-day practice and plays an important role in treatment, audit and dento-legal procedures. Creating effective endodontic records is challenging due to the scope of information required for comprehensive notes. Two audits were performed to assess the standards of endodontic record keeping by dentists in a restorative dentistry department and students on an endodontic MSc course.Methods Fifty sets of departmental records and 10 sets of student records were retrospectively evaluated against the European Society of Endodontology 2006 guidelines. Results of the first cycle of both audits were presented to departmental staff and MSc students, alongside an educational session. Additionally, departmental guidelines, consent leaflets and endodontic record keeping forms were developed. Both audits were repeated using the same number of records, thus completing both audit cycles.Results The most commonly absent records included consent, anaesthetic details, rubber dam method, working length reference point, irrigation details and obturation technique. Almost all areas of record keeping improved following the second audit cycle, with some areas reaching 100% compliance when record keeping forms were used. Statistically significant improvements were seen in 24 of the 29 areas in the departmental audit and 14 of the 29 areas in the MSc audit (P = 0.05).Conclusions Significant improvements in endodontic record keeping can be achieved through the provision of education, departmental guidelines, consent leaflets and endodontic record keeping forms.

Simplifying optimal tooth-size calculations and communications between practitioners.

The purpose of this article is to present a simple method for determining the optimal sizes of anterior teeth. This is needed because of the frequency of anomalous and missing maxillary lateral incisors. In addition to anomalous and missing incisors, other factors that create challenges for the dentist and orthodontist when designing an esthetic and occlusally sound dentition are attrition, trauma, transposition, erosion, and caries. Optimal esthetics and occlusion require correctly sized teeth in proportion to themselves and the other teeth. Orthodontics, in partnership with restorative dentistry, allows doctors to accomplish the objectives of ideal occlusion and enhanced esthetics. Data compiled from previously published research enabled us to create simple formulae to determine optimal tooth sizes, an esthetic guide worksheet to use with collaborating dentists, and a sample written communication to accompany the completed esthetic guide worksheet. The method for establishing optimal tooth sizes is presented in a manner that allows easy memorization of the formulae and determination of the best dimensions for teeth without the use of a calculator.

Roles y responsabilidades del odontólogo como auxiliar de la justicia / Dentists´ roles and responsibilities as auxiliaries to justice

La ciencia odontológica cuenta con diversas metodologías a la hora de brindar auxilio a la Justicia, tanto en la resolución de casos criminales como en procedimientos de índole civil y laboral. La odontología legal requiere de un trabajo interdisciplinario con las otrasespecialidades odontológicas. En ese contexto, el rol capital del perito odontólogo es contribuir al esclarecimiento de la identidad de unapersona. El diente es susceptible de variantes fisiológicas y patológicas en sus estructuras, como así también estigmas inherentes a los tratamientos restauradores, hechos que confiere información dental que individualiza a una persona. Las piezas dentarias pueden ser utilizadas como un arma en determinadas circunstancias, brindando información relevante sobre los caracteres odontológicos de la víctimay/o del agresor, pudiendo entonces desempeñar la odontología legal un importante rol en la investigación de situaciones de agresión sexual yabuso en todas las edades. El odontólogo en su tarea asistencial tiene la responsabilidad de labrar y documentar de manera fiel y completasu devenir profesional, pudiendo ser requerido por las autoridades encargadas de administrar Justicia en casos de responsabilidad profesional, negligencia, fraude, abuso, e identificación de restos humanos.

Dental science has various methodologies when providing aid to justice, both in solving criminal cases and civil procedures and labor issues.Legal Dentistry requires interdisciplinary work with other dental specialties. In this context, the principal role of the dentist expert is helpclarify the identity of a person. The tooth is subject to physiological and pathological variations in their structures, as well as inherentstigmas restorative treatments, facts which confers dental individualized information to a person. The teeth can be used as a weapon incertain circumstances, providing relevant information about dental characteristics of the victim and/or perpetrator can then LegalDentistry play an important role in investigating cases of sexual assault and abuse in all the ages. The dentist in their care task isresponsible for faithfully document and complete their professional procedure that may be required by the authorities responsible foradministering justice in cases of professional liability, negligence, fraud, abuse, and identification of human remains.

Australian oral health case notes: assessment of forensic relevance and adherence to recording guidelines.

BACKGROUND: Dental case notes record clinical diagnoses and treatments, as well as providing continuity of patient care. They are also used for dento-legal litigation and forensic purposes. Maintaining accurate and comprehensive dental patient records is a dental worker's ethical and legal obligation. METHODS: Australian registered specialist forensic odontologists were surveyed to determine the relevance of recorded case note items for dental identification. A dental case notes sample was assessed for adherence with odontologist nominated forensic value and compiled professional record keeping guidelines of forensic relevance. Frequency of item recording, confidence interval, examiner agreement and statistical significance were determined. RESULTS: Broad agreement existed between forensic odontologists as to which recorded dental items have most forensic relevance. Inclusion frequency of these items in sampled case notes varied widely (e.g. single area radiographic view present in 75%, CI = 65.65-82.50; completed odontogram in 56%, CI = 46.23-65.33). Recording of information specified by professional record keeping guidelines also varied, although overall inclusion was higher than for forensically desired items (e.g. patient's full name in 99%, CI = 94.01 - >99.99; named treating practitioner in 23%, CI = 15.78-32.31). CONCLUSIONS: Many sampled dental case notes lacked details identified as being valuable by forensic specialists and as specified by professional record keeping guidelines.

Dental notation for primary teeth: a review and suggestion of a novel system.

BACKGROUND: Tooth designation systems are routinely used in dental practice, for identification of teeth, recording dental data and communication among dental professionals. There are various dental notations systems for the primary and permanent dentition. The most popular are the Zsigmondy-Palmer system, the Universal Numbering System, and the FDI system. Others includes the Victor Haderup system, the Woelfel system, and the MICAP system. The majority of dental notations are focused on permanent teeth and are modified for primary teeth, even though the latter erupt before the permanent dentition. CONCLUSION: Advantages and disadvantages of notations for primary dentition are discussed and compared to a new alphanumeric system for primary teeth which is considered simple and convenient.
