Child abuse and neglect: A comparative study between dental and medical students' competencies in Germany.

INTRODUCTION: Despite children's right to a non-violent upbringing, they become daily victims of violence. Physical violence concerns mostly the head-especially the orofacial area. Therefore, dentists and paediatricians should be able to suspect possible abuse and to initiate child protection. This study aimed to record and compare the training situation and competencies of dental and medical students at Jena University Hospital regarding child abuse and neglect (CAN). MATERIALS AND METHODS: Using a three-part questionnaire about CAN, 123 medical and 77 dental students were surveyed anonymously after completing all courses on the topic. The question sets included as follows: (1) educational experiences, training content and satisfaction; (2) current knowledge regarding diagnostic, management and legal concerns; (3) self-evaluation, needs of further education and wishes. Reliability of the questionnaire was tested with kappa-statistics and assessed as good. RESULTS: Dental and medical students' overall satisfaction with CAN-related training is low. Although medical students had more knowledge on CAN, all participants showed large deficits. Better diagnostic than management skills were reported in both groups. Only 1.3% dental and 16.3% medical students felt adequately prepared to deal with CAN. 7% of all study participants stated that they can report CAN without any help. 87.0% of medical and 79.2% of dental students expressed a desire for further education. To improve their knowledge, both courses prefer seminars, followed by expert talks, lectures and simulation-based training (SkillsLab). CONCLUSION: Dental and medical students are inadequately prepared to suspect possible abuse and to deal with possible signs of CAN. Mandatory interdisciplinary courses and lectures addressing CAN are recommendable for both medical and dental curricula.

Radiation Exposure and Frequency of Dental, Bitewing and Occlusal Radiographs in Children and Adolescents.

Dental radiographs are valuable diagnostic aids for oral healthcare, but exposure to ionizing radiation carries health risks, especially in children due to their high radio-sensitivity. Valid reference values for intraoral radiographs in children and adolescents are still missing. This study aimed to investigate the radiation dose values and underlying justifications of dental, bitewing and occlusal X-rays in children and adolescents. Data from routinely executed intraoral radiographs between 2002 and 2020 with conventional and digital tube-heads were extracted from the Radiology Information System. The effective exposure was calculated from technical parameters and statistical tests performed. A total number of 4455 intraoral (3128 dental, 903 bitewing and 424 occlusal) radiographs were investigated. For dental and bitewing radiographs, the dose area product (DAP) was 2.57 cGy × cm2 and the effective dose (ED) 0.77 µSv. For occlusal radiographs, the DAP was 7.43 cGy × cm2 and the ED 2.22 µSv. Overall, 70.2% of all intraoral radiographs were dental, 20.3% bitewing and 9.5% occlusal radiographs. The most frequent indication for intraoral radiographs was trauma (28.7%), followed by caries (22.7%) and apical diagnostics (22.7%). Moreover, 59.7% of all intraoral radiographs were taken in boys, especially for trauma (66.5%) and endodontics (67.2%) (p ≤ 0.00). Girls were significantly more frequently X-rayed for caries diagnostics than boys (28.1% vs. 19.1%, p ≤ 0.00). The average ED of 0.77 µSv for intraoral dental and bitewing radiographs in this study was within the range of other reported values. The technical parameters of the X-ray devices were found at the lowest recommended levels to best limit the radiation exposure and to assure acceptable diagnostic efficacy. Intraoral radiographs were performed predominantly for trauma, caries and apical diagnostics-reflecting general recommendations for the use of X-rays in children. For improved quality assurance and radiation protection, further studies are necessary to determine the meaningful dose reference level (DRL) for children.

Effectiveness of Individual Oral Health Care Training in Hospitalized Inpatients in Geriatric Wards.

OBJECTIVE: To investigate the effectiveness of individual oral health care training (IndOHCT) on dental plaque removal and denture cleaning in hospitalized geriatric inpatients. BACKGROUND: The literature reveals neglect of hygiene and oral care in people aged over 65 years, especially in persons in need of care. Hospitalized geriatric inpatients have poorer dental health than those non-hospitalized. Furthermore, the existing literature reporting on oral healthcare training interventions for hospitalized geriatric inpatients is scarce. MATERIALS AND METHODS: This pre-post-controlled intervention study dichotomized 90 hospitalized geriatric inpatients into an intervention group (IG) and a control group (CG). Inpatients in the IG received IndOHCT. Oral hygiene was assessed using the Turesky modified Quigley-Hein index (TmQHI) and the denture hygiene index (DHI), at baseline (T0), at a second examination (T1a), and after supervised autonomous tooth brushing and denture cleaning (T1b). The influence of the Mini Mental State Examination (MMSE), Geriatric Depression Scale (GDS), and Barthel Index (BI) scores on oral hygiene was examined. RESULTS: There was no significant plaque reduction on teeth or dentures between T0 and T1a in either group. Between T1a and T1b, plaque reduction on the teeth was more effective in the IG than in the CG (p < 0.001). Inpatients with 1-9 remaining teeth removed significantly more dental plaque than inpatients with 10 or more remaining teeth. Inpatients with lower MMSE scores (p = 0.021) and higher age (p = 0.044) reached higher plaque reduction on dentures. CONCLUSIONS: IndOHCT improved oral and denture hygiene in geriatric inpatients by enabling them to clean their teeth and dentures more effectively.

Frequency of Dental X-ray Diagnostics in Children and Adolescents: What Is the Radiation Exposure?

Children are exposed to ionizing radiation through radiographs during their development for various reasons. At present, there are no officially valid reference values for dental X-rays in children and adolescents for dental X-ray diagnostics. This study retrospectively examined 9680 extraoral dental radiographs in pediatric patients between 2002 and 2020. The aim was to analyze the radiation doses in pediatric patients, which indications were used, and whether there were specific age and gender differences. The evaluation showed that radiation doses were considered low, with dose area products of 2.2 cGy × cm2 for a lateral cephalogram, 14 cGy × cm2 for an orthopantomogram (OPG), and 45 cGy × cm2 for cone beam computer tomography (CBCT). This corresponds to an effective dose of 1.5 µSv for a lateral cephalogram, 7 µSv for an OPG, and 33.8 µSv for CBCT. Of the 9680 images, 78% were orthopantomograms, and only 0.4% were CBCT images. OPG has become more important over the years, as reflected in the indication. Approximately one-third of all extraoral exposures are orthodontic indications. Overall, the indications were similar for both genders. According to the dental indications, boys were X-rayed slightly more frequently than girls (54.5-45.5%). A future publication of dose guide values and corresponding guidelines is of high priority.

Effect of Individualized Oral Health Care Training Provided to 6-16-Year-Old Psychiatric In-Patients-Randomized Controlled Study.

BACKGROUND: To assess the effect of individualized oral health care training (IndOHCT) administered to 6-16-year-old psychiatric in-patients on dental plaque removal. METHODS: 74 in-patients with mental health disorders (49 males) aged 6-16 years with a mean age of 10.4 ± 2.3 years, were randomly divided into two equal groups. At the start of hospitalization, one calibrated dentist assessed the oral health status in the hospital setting. In-patients of the intervention group (IG) received IndOHCT, while those of the control group (CG) got an information flyer. Dental plaque was assessed by the Turesky modified Quigley-Hein-Index (TI) at the start (t0) and at the end of hospitalization before (t1a) and after (t1b) autonomous tooth brushing. RESULTS: During hospitalisation, the TI was reduced in both groups (t0→t1a: IG = -0.1; CG = -0.2, p = 0.71). However, in-patients receiving IndOHCT achieved significantly higher plaque reduction rates than the controls when plaque values before and after autonomous tooth brushing were compared (t1a→t1b: IG = -1.0; CG = -0.8; p = 0.02). The effect size (ES) demonstrates the efficacy of IndOHCT (ES = 0.53), especially in children with mixed dentition (ES = 0.89). CONCLUSIONS: IndOHCT enabled hospitalized children and adolescents with mental health disorders to achieve a better plaque reduction by tooth brushing but failed to improve self-controlled routine oral hygiene.

Oral health and oral health-related quality of life in patients with chronic peripheral facial nerve palsy with synkineses-A case-control-study.

Facial nerve palsy (FP) is the most common cranial nerve lesion, leading to partial or complete immobility of the affected half of face. If food residues on tooth surfaces cannot be removed by natural self-cleaning mechanisms that this is likely to lead to an increase dental plaque formation and the risk of dental, periodontal and general diseases. It was the aim of this study to assess oral health, oral hygiene with the influence of handedness and oral health related quality of life in patients with chronic peripheral FP. This study included 86 people. Patients with FP (n = 43) in an FP-group (FPG) were matched with 43 participants without ever diagnosed FP in a control group (CG). Oral health and oral hygiene were assessed in a clinical examination performed in hospital. Decayed-missing-filled-teeth-index, periodontal-screening-index, approximal plaque index and sulcus bleeding index were used to evaluate dental caries and periodontal health status. Oral health-related quality of life data (OHQoL) was collected with the Oral health impact profile (Germany-14) by interview. Oral health parameters in the FPG were significantly worse than in the CG. The median revealed 14.3% more proximal plaque (p = 0.014), 20.8% more sulcus bleeding (p = 0.002) and more than twice as much caries (p = 0.024). The paretic side compared to the non-paretic side of patients was significantly more affected by inflammatory periodontal diseases (p = 0.032) and had a higher prevalence of caries (p = 0.163). Right-handed patients with right-sided FP performed worse than right-handed patients with left-sided FP (p = 0.004). Patients with FP described a greater limitation of OHQoL than patients without this disease (p < 0.001). In conclusion, facial nerve palsy affects oral health, oral hygiene and OHQoL of patients while handedness influences oral hygiene and oral health.

STAndard Reporting of CAries Detection and Diagnostic Studies (STARCARDDS).

AIM: The aim of this paper is to present recommendations from an international workshop which evaluated the methodology and reporting of caries diagnostic studies. As a unique feature, this type of studies is focused on caries lesion detection and assessment, and many of them are carried out in vitro, because of the possibility of histological validation of the whole caries spectrum. This feature is not well covered in the existing reporting STARD guideline within the EQUATOR Network. PARTICIPANTS AND METHODS: An international working group of 13 cariology researchers was formed. The STARD checklist was reviewed and modified for caries detection and diagnosis purposes, in a three-step process of evaluation, consensual modification, and delivery during three 2-day workshops over 18 months. Special attention was paid to reporting requirements of caries studies that solely focus on reliability. RESULTS: The STARD checklist was modified in 14/30 items, with an emphasis on issues of sample selection (tooth selection in in vitro studies), blinding, and detailed reporting of results. CONCLUSION: Following STARCARDDS (STAndard Reporting of CAries Detection and Diagnostic Studies) is expected to result in complete reporting of study design and methodology in future caries diagnosis and detection experiments both in vivo and in vitro, thus allowing for better comparability of studies and higher quality of systematic reviews. CLINICAL RELEVANCE: Standardization of caries diagnostic studies leads to a better comparability among future studies, both in vivo and in vitro.

Systematic review and meta-analysis of diagnostic studies of proximal surface caries.

AIM: This systematic review and meta-analysis aimed to assess the diagnostic accuracy and reliability of commonly used caries detection methods for proximal caries diagnostics. Visual examination (VE), bitewing radiography (BWR), laser fluorescence (LF), and fibre-optic transillumination (FOTI) were considered in detail. MATERIAL AND METHODS: PRISMA guidelines for the reporting of systematic reviews and meta-analyses were applied. The mnemonic PIRDS (problem, index test, reference test, diagnostic and study type) concept was used to guide the literature search. Next, studies that met the inclusion criteria were stepwise selected and evaluated for their quality with a risk of bias (RoB) assessment tool. Studies with low/moderate bias and sufficient reporting were considered for meta-analysis. The pooled sensitivity (SE), specificity (SP), diagnostic odds ratio (DOR), and area under the ROC curve (AUC) were calculated. RESULTS: From 129 studies meeting the selection criteria, 31 in vitro studies and five clinical studies were finally included in the meta-analysis. The AUC values for in vitro VE amounted to 0.84 (caries detection) and 0.85 (dentin caries detection). BWR ranged in vitro from 0.55 to 0.82 (caries detection) and 0.81-0.92 (dentin caries detection). LF showed higher AUC values for overall caries detection (0.91) and dentin caries detection (0.83) than did other methods. Clinical data are limited. CONCLUSION: The number of diagnostic studies with low/moderate RoB was found to be low and indicates a need for high-quality, well-designed caries diagnostic studies. CLINICAL RELEVANCE: BWR and LF showed good diagnostic performance on proximal surfaces. However, because of the low number of includable clinical studies, these data should be interpreted with caution.

Identifying and Avoiding Risk of Bias in Caries Diagnostic Studies.

Caries diagnostic studies differ with respect to their design, included patients/tooth samples, use of diagnostic and reference methods, calibration, blinding and data reporting. Such heterogeneity makes comparisons between studies difficult and could represent a substantial risk of bias (RoB) when it is not identified. Therefore, the present report aims to describe the development and background of a RoB assessment tool for caries diagnostic studies. The expert group developed and agreed to use a RoB assessment tool during three workshops. Here, existing instruments (e.g., QUADAS 2 and the Joanna Briggs Institute Reviewers' Manual) influenced the hierarchy and phrasing of the signalling questions that were adapted to the specific dental purpose. The tailored RoB assessment tool that was created consists of 16 signalling questions that are organized in four domains. This tool considers the selection/spectrum bias (1), the bias of the index (2) and reference tests (3), and the bias of the study flow and data analysis (4) and can be downloaded from the journal website. This paper explores possible sources of heterogeneity and bias in caries diagnostic studies and summarizes the relevant methodological aspects.

Systematic review and meta-analysis of diagnostic methods for occlusal surface caries.

AIM: This systematic review and meta-analysis aimed to assess the diagnostic performance of commonly used methods for occlusal caries diagnostics, such as visual examination (VE), bitewing radiography (BW) and laser fluorescence (LF), in relation to their ability to detect (dentin) caries under clinical and laboratory conditions. MATERIALS AND METHODS: A systematic search of the literature was performed to identify studies meeting the inclusion criteria using the PIRDS concept (N = 1090). A risk of bias (RoB) assessment tool was used for quality evaluation. Reports with low/moderate RoB, well-matching thresholds for index and reference tests and appropriate reporting were included in the meta-analysis (N = 37; 29 in vivo/8 in vitro). The pooled sensitivity (SE), specificity (SP), diagnostic odds ratio (DOR) and areas under ROC curves (AUCs) were computed. RESULTS: SP ranged from 0.50 (fibre-optic transillumination/caries detection level) to 0.97 (conventional BW/dentine detection level) in vitro. AUCs were typically higher for BW or LF than for VE. The highest AUC of 0.89 was observed for VE at the 1/3 dentin caries detection level; SE (0.70) was registered to be higher than SP (0.47) for VE at the caries detection level in vivo. CONCLUSION: The number of included studies was found to be low. This underlines the need for high-quality caries diagnostic studies that further provide data in relation to multiple caries thresholds. CLINICAL RELEVANCE: VE, BW and LF provide acceptable measures for their diagnostic performance on occlusal surfaces, but the results should be interpreted with caution due to the limited data in many categories.

Testing the ability for autonomous oral hygiene in hospitalized geriatric patients-clinical validation study.

OBJECTIVES: This study aimed to evaluate if the Timed Test for Money Counting (TTMC) complemented with testing the range of shoulder motion by griping the backside of the neck (NG) predicts the ability of geriatric inpatients to perform effective plaque reduction by autonomously conducted oral hygiene. MATERIAL AND METHODS: This clinical validation study involved 74 hospitalized geriatric inpatients, 48 (64.9%) females, aged between 66 and 98 years (mean age 84.1 years). Oral health status was examined. Dental plaque was assessed with the Turesky modified Quigley-Hein Index (TI) on teeth and the Denture Hygiene Index (DHI) on removable dentures. The performance and duration of TTMC and NG were recorded. After autonomous tooth brushing and denture cleaning by the patient, dental plaque was scored again with the TI and DHI. Geriatric assessment data were collected from medical records. RESULTS: Forty-nine (66.2%) geriatric inpatients completed the TTMC&NG successfully. Passing the TTMC&NG was significantly associated with better plaque removal on teeth and dentures by autonomously conducted oral hygiene. The sensitivity of the TTMC&NG for above average plaque reduction was 86.4% on teeth and 77.8% on dentures. The test revealed a negative predictive value of 75.0% to detect below average plaque reduction on teeth and 72.7% on dentures. CONCLUSIONS: The TTMC&NG served as a suitable predictor for the ability of geriatric inpatients to perform autonomously effective tooth brushing and denture cleaning. CLINICAL RELEVANCE: This simple and short test might help the medical staff to identify geriatric inpatients unable to perform effective oral hygiene by themselves.

[Oral Health in Children and Adolescents with Mental Disability and Psycho-Emotional Disorders from Lower Saxony and Thuringia]. / Mundgesundheit von Kindern und Jugendlichen mit geistiger Behinderung und psychoemotionalen Störungen aus Niedersachsen und Thüringen.

AIM: This study aimed to compare the oral health status of 6-16 year old pupils with mental disability (MD) and psycho-emotional disorders (PED) from Lower Saxony (LS) and Thuringia (TH). METHODS: Oral examination was provided for 571 pupils with MD from TH, 118 students with MD and 80 students with PED from LS. Caries experience, odontogenic infections, fissure sealants and periodontal health were recorded. Data were statistically analysed by linear and binary logistic regression after adjusting for age. RESULTS: Students with PED revealed highest caries prevalence and experience in both dentitions with highest prevalence of odontogenic infections in the primary dentition. In 6-11 year old pupils with MD, there were only minor differences in odontogenic infections between TH and LS. Pupils with PED aged 6-11 years had a more that two-fold higher risk to develop dental caries and odontogenic infections than peers with MD. Care index was higher in pupils with PED compared to those with MD in both dentitions. Pupils with MD from TH were less affected with dental caries and received better care than those from LS. Compared to peers without mental disabilities or disorders, pupils with MD or PED were more affected with dental caries in both dentitions. They revealed a lower care index and less fissure sealants. CONCLUSION: Pupils with MD or PED reveal unsatisfactory oral health status constituting a group with particular high caries risk, while those with PED are most affected by caries and odontogenic infections. The care index is insufficient especially in pupils with MD compared to those with PED or peers without disabilities and indicates disparity in oral health for this vulnerable group.

Dental Caries and Developmental Defects of Enamel in the Primary Dentition of Preterm Infants: Case-Control Observational Study.

AIM: Assessment of dental health in the primary dentition of preterm infants (PTI) including investigation of mother- and infant-related risk factors in a case-control study design. MATERIAL AND METHODS: One hundred twenty-eight infants aged 3-4 years were included. Sixty-four PTI (27 males) were randomly selected from the preterm registry of the Jena University Hospital. As a control group served 64 full-term infants (FTI) recruited from the Department of Paediatric Dentistry, matched for age and sex. Dental examinations were provided by one dentist under standard clinical conditions. Caries was scored using the International Caries Detection and Assessment System (ICDAS II) and the DMFT, gingival health using the Periodontal Screening Index, and developmental defects of enamel using the DDE index. Mother- and infant-related factors were collected via a questionnaire and from medical records. RESULTS: The caries prevalence was 50.0% (ICDAS II >0) in PTI and 12.5% (ICDAS II >0) in FTI. The caries experience was higher in PTI (DMFT 1.0 ± 3.1) than in FTI (DMFT 0.3 ± 1.0). PTI had a higher risk of caries (OR 7.0), initial lesions (OR 6.2), DDE (OR 7.5), and gingivitis (OR 6.5) than FTI. The highest risk occurred in PTI with an extremely low birth weight (<1,000 g). A higher risk of DDE was present when mothers suffered from illness during pregnancy (OR 3.9). A higher risk of caries was revealed in infants with respiratory syndrome (OR 6.2) or when their mothers had a lower socioeconomic status (OR 6.3). CONCLUSIONS: PTI had less healthy teeth than FTI and are at a higher risk for DDE, caries, and gingivitis. The poorer dental health in PTI is associated with a low birth weight, a low socioeconomic status, and mothers' illness during pregnancy.

Dental health and odontogenic infections among 6- to 16-year-old German students with special health care needs (SHCN).

OBJECTIVES: This cross-sectional study aimed to assess dental health and odontogenic infections in students with special health care needs (SHCN) in the Free State of Thuringia, Germany. METHODS: From 1283 students with SHCN aged 6-16 years, 66.0 % (n = 848 of whom are 35.7 % females and 64.3 % males) with intellectual/learning disabilities (ID/LD), physical disabilities (PD), and sensory disorders (SD) participated after informed consent in oral examinations according to WHO standards. Dental caries was assessed by dmft/DMFT, odontogenic infections by pufa/PUFA. Fissure sealants (FS) were scored in permanent molars. Data were compared to regional and national reference data and analysed by t test and age-adjusted logistic regression models. RESULTS: Students with SHCN revealed 41.2 % caries prevalence in permanent and 31.7 % in primary teeth. Highest prevalence/experience of caries and odontogenic infections in primary teeth was recorded in 6-11-year-olds with PD (65.1 %/2.3 dmft; 14.0 %/0.3 pufa). Most affected permanent teeth were observed in students with ID/LD (12-16-year-olds 59.6 %/2.4 DMFT; 6-11-year-olds 2.8 %/0.03 PUFA). All odontogenic infections in 12-16-year-olds occurred in males; n = 9 students revealed n = 9 teeth with pufa/PUFA. Students with ID/LD aged 6-11 years exhibited lowest prevalence of FS (29.0 %) and mean of 0.8 FS. Students with SHCN suffered more than twice as frequent from untreated dental caries and benefited up to 29.0 % less from FS than peers without disabilities. CONCLUSION: This first study investigating odontogenic infections of German students with SHCN revealed highest prevalence in primary teeth and in males. Oral health among students with SHCN is reduced, and FS are underutilized compared to German students without disabilities. CLINICAL RELEVANCE: Reinforcing the application of FS in students with SHCN might contribute to reducing disparities in oral health.

Clinical consequences of untreated dental caries in German 5- and 8-year-olds.

BACKGROUND: About half of all carious lesions in primary teeth of German 6- to 7-year-old children remain untreated, but no data regarding the clinical consequences of untreated dental caries are available. Therefore, this cross-sectional observational study aimed to assess the prevalence and experience of caries and odontogenic infections in the primary dentition of 5- and 8-year-old German children. METHODS: Dental examinations were performed in 5-year-old pre-school children (n = 496) and in 8-year-old primary school children (n = 608) living in the Westphalian Ennepe-Ruhr district. Schools and preschools were selected by sociodemographic criteria including size, area, ownership, socio-economic status. Caries was recorded according to WHO criteria (1997). The Lorenz curves were used to display the polarisation of dental caries. Caries pattern in 5-year-olds was categorized by Wyne's (1997) definition of early childhood caries (ECC). Odontogenic infections as clinical consequence of untreated dental caries were assessed by the pufa index. The 'untreated caries-pufa ratio' was calculated, and the Spearman's rank correlation coefficient (ρ) was used for evaluating the correlation between dmft and pufa scores. Categorical data were compared between groups using the chi-square test and continuous data were analysed by t-test. RESULTS: Caries prevalence and experience in the primary dentition was 26.2 %/0.9 ± 2.0 dmft in 5-year-olds and 48.8 %/2.1 ± 2.8 dmft in 8-year-olds. ECC type I (22 %) was the prevalent caries pattern in 5-year-olds. About 30 % of the tooth decay was treated (5y: 29.7 %/8y: 39.3 %). The Lorenz curves showed a strong caries polarisation on 20 % of the children. Pufa prevalence and experience was 4.4 %/0.1 ± 0.5 pufa in 5-year-olds and 16.6 %/0.3 ± 0.9 pufa in 8-year-olds. In 5-year-olds 14.2 % and in 8-year-olds 34.2 % of the d-component had progressed mainly to the pulp. A significant correlation between dmft and pufa scores exists in both age groups (5y: ρ = 0.399; 8y: ρ = 0.499). First deciduous molars were most frequently affected by odontogenic infections, presenting virtually all pufa scores (>95 %). CONCLUSIONS: Prevalence and experience of odontogenic infections and the untreated caries-pufa ratio were increasing from the younger to the elder children. Dmft and pufa scores in primary teeth predict a higher caries risk in permanent teeth. The pufa index highlights relevant information for decision makers to develop effective oral health care programs for children at high risk for caries.
