Associations of adverse childhood experiences with caries and toothbrushing in adolescents. The Young-HUNT4 Survey. BMC Oral Health 2023; 23:760. [PMID: 37838651 PMCID: PMC10576322 DOI: 10.1186/s12903-023-03492-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 10/04/2023] [Indexed: 10/16/2023] Open
Abstract
BACKGROUND Adverse childhood experiences (ACEs) are associated with poor oral health. Using a life course theoretical framework, this study explored the associations of specific and cumulative ACEs with caries and toothbrushing frequency in a Norwegian adolescent population. METHODS Participants were adolescents (n = 6351) age 13-17 years from The Young-HUNT4 Survey. Clinical data were retrieved from dental health records. Oral health outcomes were toothbrushing frequency, dentine caries experience (Decayed, Missing, and Filled Teeth - DMFT), and enamel caries. ACE exposure variables were physical abuse, sexual abuse, witness to violence, parental separation/divorce, parental alcohol problems, and bully victimization. Negative binominal regression models (incident rate ratios, IRRs; 95% confidence intervals, CIs) were used to determine the associations of the various ACEs with caries; logistic regression analyses (odds ratios, ORs; 95% CIs) were used to estimate associations with toothbrushing frequency. Potential effect modification by age was assessed using likelihood ratio test. RESULTS Adolescents exposed to physical abuse by others, sexual abuse by peers, parental separation/divorce, bullying, or who had witnessed violence, were more likely to report non-daily toothbrushing compared with those with no exposure to the given ACEs. Each cumulative increase in ACE exposure was associated with a 30% higher likelihood of non-daily toothbrushing (OR 1.30, 95% CI 1.19-1.42). Similarly, increasing number of adversities were associated with both higher dentine caries experience (IRR 1.06, 95% CI 1.02-1.09) and higher enamel caries (IRR 1.07, 95% CI 1.03-1.11). This effect was modified by age (13-15 vs. 16-17 years) for dentine caries experience. Furthermore, there was evidence of effect modification by age with bully victimization for both toothbrushing frequency (Pinteraction = 0.014) and dentine caries experience (Pinteraction < 0.001). Specifically, bully victimization was associated with a higher likelihood of non-daily toothbrushing (OR 2.59, 95% CI 1.80-3.72) and higher dentine caries experience (IRR 1.30, 95% CI 1.14-1.50) among 16-17-year-olds. CONCLUSIONS Several specific ACEs were associated with non-daily toothbrushing and a higher caries experience among Norwegian adolescents in the Young-HUNT4 Survey.

Association between self-reported dental fear and exposure to violence among adolescents-A population-based study. Int J Paediatr Dent 2022; 32:812-818. [PMID: 35348256 PMCID: PMC9790500 DOI: 10.1111/ipd.12966] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 03/07/2022] [Accepted: 03/12/2022] [Indexed: 12/30/2022]
Abstract
BACKGROUND The etiology of dental fear (DF) is multifactorial and involves other contributing factors than dental traumatic experiences. AIM To study, among adolescents, associations between DF and exposure to child physical abuse (CPA), intimate partner violence (IPV), and bullying. DESIGN We extracted data from a population-based survey of 4977 adolescents who were 15-17 years old in 2017. The questionnaire queried socioeconomic background factors, DF, self-perceived oral health, general health, and exposure to child abuse. To estimate associations between DF and exposure to child abuse, we used multivariate logistic regression analysis. RESULTS Overall, 8.2% reported DF, girls (10.5%) reported DF significantly more often than boys (5%), and adolescents not identifying themselves as girl or boy reported the highest prevalence of DF (25.5%; p < .001). 15.3% had been exposed to child physical abuse; 11.1%, to IPV; and 11.2%, to bullying. Experiences of IPV and bullying, but not physical abuse, were statistically significantly associated with DF. The odds of developing DF for adolescents exposed to any type of violence was 1.9 times the odds for adolescents with no exposure to child abuse. CONCLUSION Exposure to violence is associated with dental fear in adolescents.

Patient satisfaction with root canal treatment and outcomes in the Swedish public dental health service. A prospective cohort study. Int Endod J 2021; 54:1462-1472. [PMID: 33969501 DOI: 10.1111/iej.13548] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Accepted: 05/06/2021] [Indexed: 02/02/2023]
Abstract
AIM To document satisfaction with root canal treatment procedures and outcomes among patients treated at Swedish public dental clinics. METHOD The original material comprised 243 patients who began root canal treatment (RCT) at 20 public dental clinics in the county of Västra Götaland, Sweden. One to three years later, 236 (97.1%) were posted a questionnaire of eight items, rating patient perceptions of RCT-completion, present pain intensity and satisfaction with the RCT. To evaluate the reliability of the original responses, the first 50 respondents were mailed a follow-up questionnaire. Both descriptive and analytical statistics were used to compare respondents and non-respondents and tooth groups. RESULTS One hundred and fifty-nine patients (67.4%) responded: 86 (54.1%) women and 73 (45.9%) men. The mean age 52.5 years, was higher than for non-respondents (P<0.001). A completed root filling was registered for the majority of the teeth (n = 112, 70.9%), but significantly fewer molars had been completed (n = 46, 59.7%, P = 0.02). Fifty percent (n = 59) of the patients reported current pain, mostly mild in intensity (n = 45, 38.1%). One hundred and twenty-three patients (80.9%) recalled experiencing pain during RCT. The highest satisfaction was registered for the item 'chewing ability' (mean = 1.6, SD = 1.9). The majority of patients (n = 114, 75.0%) stated that in retrospect they would still have chosen RCT. However, these patients belonged to the group which either registered the tooth as still present, or had not experienced much discomfort during or after RCT. Forty-four patients (88.0%) responded to the second questionnaire. The reliability of the responses was good. In summary, one to 3 years after beginning RCT at a public dental clinic, patient satisfaction was high, even though every fourth molar had been extracted or treatment had not been completed and half the patients reported persistent pain. The reliability of the patients' responses was considered to be good. CONCLUSIONS The results indicate a need for further clinical observational studies of RCTs undertaken in general dental practice, with special reference to patient-centred outcomes.

Self-reported symptoms of temporomandibular pain and jaw dysfunction in adolescents are associated with exposure to violence. J Oral Rehabil 2021; 48:765-773. [PMID: 33774844 DOI: 10.1111/joor.13171] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 02/17/2021] [Accepted: 03/10/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND Temporomandibular disorders (TMDs) are multifactorial, and high levels of stress seem to increase symptoms. The association with exposure to violence has not been explored in adolescent populations. OBJECTIVE To examine the association of self-reported symptoms of temporomandibular pain and jaw dysfunction with child physical abuse, intimate partner violence, forced sexual intercourse, and bullying victimisation. METHODS An epidemiological, cross-sectional, school-based study was conducted in Olinda, northeast Brazil. The sample comprised 2,431 adolescents aged 14-19 years. TMD-related symptoms and exposure to violence were assessed with questions from the 3Q/TMD screener and queries on exposure to different forms of violence. Multilevel logistic regressions were conducted to evaluate how 3Q screen-positive responses are associated with self-reported exposure to violence. RESULTS Self-reported TMD-related symptoms had a prevalence of 40.5%. Significantly more females than males screened positive to all 3Q/TMD questions (p < .001). Adolescents experiencing intimate partner violence (p = .012) and bullying (p < .001) had significantly higher odds of 3Q positive responses than those who reported no exposure to violence. Significant associations of TMD-related symptoms with forced sexual intercourse (p = .014) and with bullying (p = .007) were observed. CONCLUSION Adolescents with self-reported symptoms of temporomandibular pain and jaw dysfunction were significantly more often exposed to some type of violence. The number of adolescents reporting TMD-related symptoms increased in a dose-response manner with the number of violence forms the individual had experienced.

Determinants of self-perceived oral health in adolescents: A cross-sectional study. Int J Paediatr Dent 2021; 31:254-261. [PMID: 32419168 DOI: 10.1111/ipd.12664] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 04/30/2020] [Accepted: 05/07/2020] [Indexed: 12/31/2022]
Abstract
BACKGROUND Self-perceived oral health (SPOH) is a summary of multiple determinants related to oral health and has been suggested for use in clinical practice as a health assessment tool. AIM To analyse determinants of SPOH among adolescents. DESIGN In 2018, we selected 1742 participants from eight high schools in Olinda/PE, Brazil, using a multistage stratified cluster sample. The main survey item of SPOH was 'How would you rate your oral health'. Determinants of were queried with a questionnaire and a clinical examination: socio-demographic variables, exposure to family violence, somatic symptoms, and orofacial and general health factors. Pearson's chi-square test and logistic regressions evaluated associations between determinants and SPOH. RESULTS Very poor SPOH had a prevalence of 8.7%. Nearly half (43.5%) rated their oral health as 'fair'. Very poor SPOH was associated with poor self-perceived general health (OR = 2.60), anterior open bite (OR = 2.24), not cohabiting with one or both parents (OR = 2.40), caries experience (OR = 1.93), dental pain (OR = 1.91), and temporomandibular disorders (OR = 1.77). CONCLUSION Very poor self-perceived oral health indicates life stress and associates with poor oral conditions. Assessments should be used to explore individual treatment needs and abilities to comply with recommendations.

Abstract
Essentially, root fillings are performed to preserve natural teeth. Over time, however, some root-filled teeth will inevitably be extracted. The aim of this historical prospective cohort study in the adult Swedish population was to identify factors associated with extractions within 5 y of registration of a root filling. The cohort consisted of all those whose root fillings had been reported to the tax-funded Swedish Social Insurance Agency (SSIA) in 2009. Demographic data on the individuals registered with a root filling (sex, age, country of birth, disposable income, educational level, and marital status) were received from Statistics Sweden or the SSIA. Dental care setting, tooth type, and any registration of subsequent restorations within 6 mo were received from the SSIA. Multivariable regression analysis was used, and P < 0.05 was considered statistically significant. In total, 216,764 individuals had been registered with at least 1 root filling. Individuals (n = 824) without complete data were excluded from the analyses. After 5 y, 9.3% of the root-filled teeth had been registered as extracted. Logistic regression analysis found significant associations for all variables except country of birth, disposable income, and educational level. The highest odds ratios for extractions were associated with the type of restoration: teeth with no registration of any restoration and teeth with a direct restoration combined with a post were 3 times more likely to undergo extraction than teeth restored with an indirect restoration combined with a post and core. Overall, high odds ratios for extractions were associated with any type of composite restoration, including composite fillings and crowns combined with or without any post. In summary, after root filling in the Swedish adult population, several individual- and tooth-specific variables were associated with extraction. The reasons for the extractions remain to be studied further.

Child physical abuse, declining trend in prevalence over 10 years in Sweden. Acta Paediatr 2020; 109:1400-1408. [PMID: 32031703 DOI: 10.1111/apa.15215] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Revised: 01/19/2020] [Accepted: 02/05/2020] [Indexed: 11/30/2022]
Abstract
AIM To study trends in prevalence and risk factors of child physical abuse over 10 years in Sweden. METHODS This study analysed responses from school surveys in 2008, 2011, 2014 and 2017 in Södermanland County, Sweden with average 5125 respondents per year, 15 and 17 years old. There were identical questions on exposure to violence and risk factors including parental employment, separated parents, disability or disease, foreign background and lack of adult support. Intimate partner violence was included at three occasions. Data were analysed with bi- and multivariate models, and mean of accumulated risks were compared. RESULTS Child physical abuse decreased significantly between 2008 and 2017. Repeated abuse decreased to a less degree than abuse once. In bivariate analyses, the share of risk factors declined for those exposed to physical abuse. In multiple analyses, it was found significant associations with exposure. There was and a dose-relationship between numbers of accumulated risk categories and self-reported abuse. CONCLUSION Exposure to child physical abuse decreased substantially between 2008 and 2017. However, prevalence of abuse is still unacceptable, and the finding that prevalence of the more severe forms of CPA decreased less during the same time, draws attention to the need of ongoing efforts.

Abstract
AIM To test the hypothesis that in the daily routine of a specialist clinic in endodontics that irrigation during root canal preparation with 3.0% NaOCl will result in fewer postoperative samples with cultivable bacteria than irrigation with 0.5% buffered NaOCl but, at the same time, will not result in a higher frequency of postoperative pain nor swelling. METHODOLOGY Two hundred ninety-eight patients were enrolled in the study and were randomly assigned into two groups - 0.5% NaOCl and 3% NaOCl. All endodontic diagnoses were included. Root canal treatment was performed, and bacterial sampling was carried out prior to root filling. The patients were requested to complete a form regarding pain and swelling seven days postoperatively. Fisher's exact test, Mann-Whitney U-test, Mantel-Haenszel chi-squared and the chi-squared test with a significance level of P < 0.05 were used for statistical analysis. Multivariable logistic regression was used to adjust for confounders. RESULTS In the 0.5% NaOCl group, 18 (13.4%) of the root canal samples were positive; in the 3% NaOCl group, the corresponding number was 24 (18.6%). The mean difference of -5.2% (95% CI: -14.8 to 4.4) was not significant (P = 0.33). In the 0.5% NaOCl group, 57 (53.8%) patients reported some pain; in the 3% group, the corresponding number was 56 (53.3%). The mean difference of 0.4 (95% CI: -14.0 to 14.8) was not significant (P = 1.0). In the 0.5% NaOCl group, 5 (5.1%) patients reported swelling; in the 3% NaOCl group, the corresponding number was 18 (17.8%). The mean difference was 12.7 (95% CI: 3.1-22.4), which was significant (P = 0.0084). CONCLUSIONS The difference in the concentration of NaOCl (0.5% vs 3%) had no significant impact on the number of positive cultures and did not influence either the frequency or the magnitude of postoperative pain. A significantly higher incidence of postoperative swelling was recorded for patients who received a greater concentration of NaOCl (3%).

Abstract
AIM To study patient- and tooth-specific characteristics of teeth indicated for root canal treatment, in the public dental service of the county of Västra Götaland, Sweden. METHODOLOGY During a designated 8-week period, general dental practitioners working at 20 different public dental clinics consecutively registered indications for undertaking root canal treatment. The patients' subjective level of pain was also registered (visual analogue scale) at the very first appointment. The following information was retrieved from computerized dental records and radiographs: gender, age, number of remaining teeth, tooth group, previous restoration, number of restored surfaces, dental caries and tooth substance loss. Gender and age were compared using both descriptive and analytical statistics. RESULTS The material comprised 243 teeth in 243 patients: 128 (52.7%) women and 115 (47.3%) men, mean age 48.3 years. Molar teeth predominated (47.7%). Most of the teeth (83.5%) had previously been restored and exhibited significant loss of tooth substance, more than a third of the crown (71.3%). Dental caries was present in 127 teeth (62.9%). Dental trauma was implicated in only seven cases (2.9%). Initial treatment was frequently undertaken at an emergency visit, for relief of symptoms (64.9%). The most commonly registered indication was pulpal necrosis with apical periodontitis (38.1%), followed by pulpitis (37.7%). Retreatment of a root filled tooth was reported in 18 teeth (7.4%). CONCLUSIONS In the general Public Dental Service of Sweden, root canal treatment is most frequently undertaken in molars. The primary indication is relief of symptoms. Retreatment of root filled teeth is uncommon.

Abstract
AIM To study the demographics of Swedish adults who had received a root filling, followed by extraction during the following 5-6 years in comparison with subjects who had undergone a corresponding root filling with an uneventful outcome. METHODOLOGY The root filled maxillary first molar was chosen as the comparison model. The Swedish Social Insurance Agency provided data on all teeth reported as root filled in Sweden during 2009. A comparison group, equally large as the study group, was constructed by randomly selecting subjects with root filled maxillary first molars, which had not subsequently been extracted, that is, an uneventful outcome. Demographic data on the subjects were obtained from Statistics Sweden: country of birth, disposable income, educational level, age, civil status and gender. Chi-square, t-tests and logistic regression were used for statistical analyses. RESULTS In the year 2009, 36 139 maxillary first molar teeth were reported to have been root filled, 4362 (12.1%) of which were then recorded as extracted during the following 5-6 year period. Only minor intergroup differences were noted: 86.5% of the study group were Swedish-born, compared with 84.4% of the comparison group (P = 0.007). Women comprised 53.2% of the study group and 50.5% (P = 0.01) of the comparison group. There was an association between extractions and gender as well as age; men had a lower odds ratio (OR) for extraction OR, 0.87; confidence interval (CI), 0.80-0.95. For every additional year, the chance for extraction was higher OR, 1.01; CI, 1.01-1.01. No other significant differences were detected. CONCLUSIONS There was only little or no demographic differences between the study group, comprising Swedish adults who had undergone root filling of one of their maxillary first molars in 2009 and subsequent extraction during the following 5-6 years, and the comparison group, with uneventful outcomes after a corresponding root filling.

Abstract
Child abuse and neglect (CAN) are likely to have negative consequences on health; however, for oral health, studies on associated outcomes are sparse. The purpose of this study was to assess oral health and oral health behaviors in relation to suspected CAN among children being investigated by the Swedish Social Services. The material comprised data from the Social Services and dental records; the sample, 86 children and 172 matched controls. The children in the study group had a higher prevalence of dental caries than the control group; in addition, levels of non-attendance and dental avoidance were high, as was parental failure to promote good oral health. We found four factors that, taken together, indicated a high probability of being investigated because of suspected CAN: prevalence of dental caries in primary teeth, fillings in permanent teeth, dental health service avoidance, and referral to specialist pediatric dentistry clinics. If all four factors were present, the cumulative probability of being investigated was 0.918. In conclusion, there is a high prevalence of dental caries, irregular attendance, and a need for referral a pediatric dental clinic among Swedish children under investigation due to suspected CAN. Social context is an important factor in assessing the risk of developing dental caries, the inclination to follow treatment plans, and the prerequisites for cooperation during treatment. Routinely requesting dental records during an investigation would provide important information for social workers on parental skills and abilities to fulfill the basic needs of children.

Comparative analysis of general dental practitioners' fees and scheduled fees for root canal treatment and coronal restorations in the adult population of Sweden: a 5-year follow-up of data from the Swedish Dental Register. Int Endod J 2017; 51:141-147. [PMID: 28708240 DOI: 10.1111/iej.12817] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2017] [Accepted: 07/10/2017] [Indexed: 12/17/2022]
Abstract
AIM To investigate the fees charged by Swedish dentists for root fillings, coronal restorations and further dental interventions during a follow-up period of 5-6 years. METHODOLOGY A total of 248 299 root fillings were linked with the tooth, the patient and the provider and entered into the Swedish Social Insurance Agency register in 2009. The data register also recorded the subsidy-based (scheduled) fee and the fee actually charged for the root fillings. Fees charged for direct or indirect coronal restorations and additional interventions during the follow-up period were also recorded. One-way anova and t-test were used for statistical analysis. RESULTS The mean overall fee charged for a root filling was approximately 332 Euro and differed only marginally (13 Euro) from the scheduled fee. The total mean fee for preservation of a root filled tooth was 717 Euro, which included the root canal treatment, the coronal restoration and any additional interventions during the follow-up period. The fees for indirectly restored root filled teeth were significantly higher (1105 Euro) than for directly restored teeth (610 Euro), despite further additional treatment (P < 0.001). The mean fee for teeth which were subsequently extracted was higher (769 Euro) than for the retained teeth (711 Euro) (P < 0.001). CONCLUSIONS Fees charged by Swedish dentists for root canal treatment were in accordance with the scheduled fees. The overall mean fee was significantly higher for root filled teeth with indirect restorations than for teeth with direct coronal restorations. However, prospective clinical cost-effectiveness studies are needed to analyse the total costs.

Abstract
BACKGROUND Dental professionals are required to report suspicions of child maltreatment to the social services. As yet, no studies assess the prevalence of these mandated reports from dental care services or their content. AIM This study investigates the prevalence and characteristics of mandated reports from dental professionals to the social services. Furthermore, it analyses associations between dental professionals reporting suspicions of maltreatment with such reports from other sources. DESIGN The study collected dental mandatory reports from within one municipality of Sweden during 2008-2014. The material consisted of a total of 147 reports by dental professionals regarding 111 children. RESULTS The total prevalence of reports from dental care services to the social services was 1.5 per 1000 children with a significant increase between 2008 and 2011 (P < 0.001). The primary cause for a report concerned parental deficiencies in care (n = 93) and secondly, a concern for dental neglect (n = 52) (P < 0.001). Among all reports, 86% involved children with prior contacts with the social services. CONCLUSION Reports to the social services from dental care services on suspicions of child maltreatment concern parental deficiencies (failure to attend appointments) and neglect (dental neglect). Mandated reports from dental care services often co-occur with other mandated reports.

Abstract
AIM To study if treatment under general anaesthesia (GA) is associated with dental neglect or dental disability. STUDY DESIGN This was a retrospective study. METHODS Dental records of all children in the age 0-6 years who underwent GA at a specialist paediatric dentistry clinic during 2006-2011 were studied with regard to decayed-missed-filled teeth, traumatic injuries, emergency visits, behaviour management problems and the history of attendance. The final sample consisted of 134 children. Matched controls were selected among recall patients who had not received treatment under GA. STATISTICS Fishers exact test or Pearson Chi-square test analysed response distribution and comparisons between groups, and for multivariate analyses, logistic regression was used. RESULTS The results show that children treated under GA had significantly higher caries prevalence, apical periodontitis and infections due to pulpal necrosis. Dental neglect as well as dental disability was significantly more prevalent in the GA group compared to the control group. In a multivariate analysis with dental neglect as independent factor, dental disability was the only significant factor (p = 0.006). CONCLUSIONS Children treated under general anaesthesia were significantly more often diagnosed with both dental neglect and dental disability. Dental disability was the only factor significantly related to dental neglect. There is a need for improved documentation in the dental records to better identify dental neglect and dental disability, and also a continued training of dentists regarding child protection.

Abstract
UNLABELLED One barrier to cross during genetic engineering is the restriction-modification system found in many bacteria. In this study, we developed a fast and reliable method for mapping the recognition and cleavage site of the restriction endonucleases. Clostridium pasteurianum, a model organism for the study of nitrogen fixation, has been found to harbour at least two restriction-modification systems including the restriction endonucleases CpaPI, which is an isoschizomer of MboI and CpaAI. Dam-methylated DNA was used to isolate the activity of CpaAI. Exposing freshly prepared cell lysate to known nucleotide fragments and directly sequencing the pool of digested nucleotide fragments enabled identification of the cleavage sites in the fragments. By aligning the sequences adjacent to the cleavage site, it was possible to identify the recognition sequence. Using this method, we successfully located all CpaAI recognition and cleavage sites within the template sequence. By modifying DNA with both Dam and CpG methylases (M.SssI) and thereby preventing digestion by CpaPI and CpaAI, no further endonuclease activity was detected. SIGNIFICANCE AND IMPACT OF THE STUDY Restriction-modification systems are important barriers to successful genetic modification in many bacterial species. In this study, we demonstrate an efficient and general applicable method for identifying endonuclease recognition and cleavage sites. For the study and the trails, the model organism for nitrogen fixation Clostridium pasteurianum was used. The method was proven to be reliable, and by modifying DNA at the identified sites, it is possible to prevent digestion.

Abstract
This systematic review evaluates the diagnostic accuracy of radiographic methods employed to indicate presence/absence and changes over time of periapical bone lesions. Also investigated were the leads radiographic images may give about the nature of the process and the condition of the pulp in nonendodontically treated teeth. Electronic literature search included the databases PubMed, Embase and CENTRAL from January 1950 to June 2011. All languages were accepted provided there was an abstract in English. The MeSH terms were 'Cone beam computed tomography (CBCT)', 'Radiography, panoramic', 'Periapical diseases', 'Dental pulp diseases', 'Sensitivity and specificity', 'receiver operating characteristics (ROC) curve', 'Cadaver', 'Endodontics' and 'Radiography dental'. Two reviewers independently assessed abstracts and full text articles. An article was read in full text if at least one of the two reviewers considered an abstract to be potentially relevant. Altogether, 181 articles were read in full text. The GRADE approach was used to assess the quality of evidence of each radiographic method based on studies of high or moderate quality. Twenty-six studies fulfilled criteria set for inclusion. None was of high quality; 11 were of moderate quality. There is insufficient evidence that the digital intraoral radiographic technique is diagnostically as accurate as the conventional film technique. The same applies to CBCT. No conclusions can be drawn regarding the accuracy of radiological examination in identifying various forms of periapical bone tissue changes or about the pulpal condition.

Abstract
Mandatory reporting to the social services is required by dental professionals when suspicion of child abuse or neglect occurs. The objective of this study was to analyze the recommendations previously made by the Ombudsman for Children in Sweden. The aim was to study the association between having guidelines and the inclination to report to the social services and also the association between management of multiple missed appointmens and reports to the social service. A web-based questionnaire was sent to the clinical department heads (CDH) of all PDS in Sweden, distributed and authorized by The Ombudsman for Children in Sweden. The response frequency was 95% and all county councils of Sweden were represented. The results showed regional differences regarding management of suspected child abuse, neglect and dental neglect. Clinical department heads that had reported to the social services more often had guidelines on child abuse and neglect (p < 0.000). Management of repeated missed appointments varied between clinics. Those who never had made a report to the social services more often stated that the reason for missed appointments was parental negligence (p = 0.004) and less often thought it was an actual maltreatment (p = 0.003), and they more often rescheduled when a child repeatedly missed an appointment (p = 0.013). Sixty-four percent of the clinical department heads requested additional support in this matter. In conclusion, public dental service clinics in Sweden are significantly more likely to report to the social services if guidelines regarding child abuse and neglect are available.

Abstract
AIM To compare the diagnostic information and radiation dose between intraoral radiography and computed tomography (CT) in re-treatment decision making concerning root fillings in maxillary molars. METHODOLOGY Thirty-nine root-filled maxillary molars with suspected apical periodontitis were examined with two intraoral periapical radiographs and CT. Presence of periapical lesion/s per tooth and root were analysed for both techniques. In addition, in the CT images, the number of root canals, erosion, or perforation of cortical bone plates, and the distance between palatal root and cortical bone plates were evaluated. Radiation dose for CT was registered and calculated; and that of periapical radiographs used as reported previously (Ekestubbe et al. 2004). RESULTS Periapical radiographs revealed periapical lesions in 33 teeth compared with 38 on CT images. A lesion of any root was detected more often with CT. The mesiobuccal root had two root canals in 30 teeth of which 27 of the MB2 canals were not filled, and 22 roots with an unfilled canal were associated a periapical lesion. Distances to palatal root, from the buccal and palatal cortex were measured in CT and varied between 5.0-12.0 mm and 0-4.0 mm, respectively. Based on the radiographic information, a variety of treatment alternatives were suggested. Mean effective dose of periapical radiographs was 0.02 mSv and that of CT 0.055 mSv. CONCLUSIONS Computed tomography may give important information in re-treatment decision when considering root fillings in maxillary molars. The radiation dose should be considered individually.

Abstract
Application of thermal treatment at 100-140 degrees C as a pretreatment method prior to anaerobic digestion of a mixture of cattle and swine manure was investigated. In a batch test, biogasification of manure with thermally pretreated solid fraction proceeded faster and resulted in the increase of methane yield. The performances of two thermophilic continuously stirred tank reactors (CSTR) treating manure with solid fraction pretreated for 40 minutes at 140 degrees C and non-treated manure were compared. The digester fed with the thermally pretreated manure had a higher methane productivity and an improved removal of the volatile solids (VS). The properties of microbial communities of both reactors were analysed. The specific methanogenic activity (SMA) test showed that both biomasses had significant activity towards hydrogen and formate, while the activity with the VFA - acetate, propionate and butyrate - was low. The kinetic parameters of the VFA conversion revealed a reduced affinity of the microbial community from the CSTR fed with thermally pre-treated manure for acetate, propionate and butyrate. The bacterial and archaeal populations identified by t-RLFP analysis of 16S rRNA genes were found to be identical in both systems. However, a change in the abundance of the species present was detected.

Abstract
The antimicrobial efficacy of endodontic procedures performed in one-visit (including a 10-min intraappointment dressing with 5% iodine-potassium-iodide) was compared with a two-visit procedure (including an interappointment dressing with calcium-hydroxide paste). Teeth with apical periodontitis (n = 96) were randomly assigned to either group. Root canal sampling and culturing were performed before and immediately after instrumentation, and after medication. Initial sampling demonstrated the presence of microorganisms in 98% of the teeth. Postinstrumentation sampling showed reduction of cultivable microbiota. Antibacterial dressing further reduced the number of teeth with surviving microbes. In the postmedication samples, residual microorganisms were recovered in 29% of the one-visit teeth and in 36% of the two-visit treated teeth. No statistically significant differences between the groups were discerned. It was concluded that from a microbiological point of view, treatment of teeth with apical periodontitis performed in two appointments was not more effective than the investigated one-visit procedure.

Abstract
AIM There is substantial variation amongst dentists in the management of symptom-free periapical lesions in root-filled teeth. It has been suggested that this variation can be understood as clinicians' choice of different cut-off points on a continuous periapical health scale (the 'Praxis Concept (PC) theory'). Based on this suggestion, an individual's inclination to propose retreatment can be expressed in the Retreatment Preference Score (RPS). In the present study it was hypothesized that: (i) the PC theory is valid amongst experienced endodontists; and that (ii) interindividual variation in RPS can be explained by a corresponding variation in the perceived benefit of endodontic retreatment. METHODOLOGY The RPS was determined for 16 experienced Swedish endodontists. The retreatment benefit (RTB) was defined as the gain in utility when a root-filled tooth with a persistent periapical lesion ('health state B') moved to a state where the lesion had healed ('health state A'). For each individual the utility values of the two health states were measured by means of the standard gamble technique. RESULTS The RPS and RTB were found to be subjected to substantial inter- and intrarater variation. The decision makers acted in accordance with the PC theory. No significant correlation between RPS and RTB was detected. CONCLUSIONS Findings suggest that the PC theory is valid amongst endodontic experts. The study did not support the notion that the more potential utility that could be produced, the more the individual dentist should tend to perform retreatment. However, alternative consequentialist strategies focusing low risk taking may be involved.

Abstract
Epidemiological surveys have reported that 25%-35% of root filled teeth are associated with periapical radiolucencies. Descriptive studies have demonstrated that clinicians' decision making regarding such teeth are subject to substantial variation. A coherent model to explain the observed variation has not been produced. In the present thesis a "Praxis Concept theory" was proposed. The theory suggests that dentists perceive periapical lesions of varying sizes as different stages on a continuous health scale. Interindividual variations can then be regarded as the result of the choice of different cut-off points on the continuum for prescribing retreatment. In the present study experiments among novice and expert decision makers gave evidence in favour of the theory. Data also suggested that the choice of retreatment criterion is affected by values, costs of retreatment and technical quality of original treatment. From a prescriptive point of view, the presence of a persistent periapical radiolucency has often been used as a criterion of endodontic "failure" and as an indication for endodontic retreatment. As an alternative decision strategy, the use of decision analysis has been proposed. Logical display of decision alternatives, values of probabilities, utility values (U-values) of the different outcomes and calculation of optimal decision strategy are features of this theory. The implementation of this approach is impeded by the uncertainty of outcome probabilities and lack of investigations concerning U-values. U-values of two periapical health states in root filled teeth (with and without a periapical lesion respectively) were investigated in a group of 82 dental students and among 16 Swedish endodontists. Two methods were used to elicit U-values: Standard gamble and Visual Analogue Scale. Large interindividual variation for both health states were recorded. The difference in U-values between the two health states was found to be statistically significant regardless of assessment method. Compared with Standard gamble Visual Analogue Scale systematically produced lower ratings. U-values were found to change considerably in both the short and long-term. Any significant correlation between endodontists' U-values and retreatment prescriptions could not be demonstrated. Surgical and nonsurgical retreatment were randomly assigned to 95 "failed" root filled teeth in 92 patients. Cases were followed clinically and radiographically for four years postoperatively. At the 12-month recall a statistically significant higher healing rate was observed for teeth retreated surgically. At the final 48-month recall no systematic difference was detected. Patients were found to be more subject to postoperative discomfort when teeth were retreated surgically compared with nonsurgically. Consequently, surgical retreatment tended to be associated with higher indirect costs than a nonsurgically approach. In the final part of the thesis it is argued that retreatment decision making in everyday clinical practice normally should be based on simple principles. It is suggested that in order to achieve the best overall consequence a periapical lesion in a root filled tooth that is not expected to heal should be retreated. Arguments to withhold retreatment should be based on (i) respect for patient autonomy, (ii) retreatment risks or (iii) retreatment costs.

Abstract
Endodontic retreatment decision-making must include an appraisal of the costs of the different strategies proposed. In addition to direct costs, postoperative discomfort may have other consequences in terms of time off work, unscheduled visits and suffering. To establish a foundation for the appraisal of such indirect and intangible costs the present study was set up in which patients' assessments of pain and swelling after surgical and nonsurgical retreatment procedures were recorded. Ninety-two patients with 95 root-filled incisors and canine teeth exhibiting apical periodontitis were included in the study. The mode of retreatment was randomly assigned. Each day during the first post-treatment week patients assessed their degree of swelling and pain on horizontal 100-mm visual analog scales (VAS). The scales ranged from "no swelling" to "very severe swelling" and "no pain" to "intolerable pain", respectively. Consumption of self-prescribed analgesics and time off work were also recorded. Significantly more patients reported discomfort after surgical retreatment than after nonsurgical procedures. High pain scores were most frequent on the operative day while swelling reached its maximum on the first postoperative day followed by progressive decrease both in frequency and magnitude. Postoperative symptoms associated with nonsurgical retreatment were less frequent but reached high VAS values in single cases. Analgesics were significantly more often consumed after periapical surgery. Patients reported absence from work mainly due to swelling and discoloration of the skin. This was found to occur only after surgical retreatment. Conclusively, surgical retreatment resulted in more discomfort and tended to bring about greater indirect costs than nonsurgical retreatment.

Abstract
Information of "success" rates after surgical or nonsurgical endodontic retreatment is abundant but inconclusive. Reported healing frequencies vary between 45% and 90%. The present study was designed to find any systematic difference between the methods. Nonsurgical and surgical retreatment was randomly assigned to 95 endodontically "failed" cases. The outcome of the procedures was clinically and radiographically recorded, and followed for 4 years. At the 12-month recall, a statistically significant (p < 0.05) higher healing rate was observed for cases surgically retreated. At the final 48-month examination, no such difference was found. These findings may be explained by (a) slower healing dynamics in the nonsurgical group and (b) the event of late "failures" in the surgical group. Within the latter category, four cases classified as healed after 1 yr failed at the final follow-up. Conclusively, this study failed to show any systematic difference in the outcome of surgical and nonsurgical endodontic retreatment. Surgical retreatment seems to result in more rapid periapical bone fill, but also may imply a higher risk of "late failures." From a scientific point of view, the length of the follow-up period is very important and may strongly influence the conclusions made.

Abstract
To explain dentists' variation in endodontic retreatment decision making a praxis concept (PC) has been generated. PC assumes that practitioners operate along a health continuum. Various periapical conditions are then perceived as different stages on a continuous health scale, based on their radiographic appearance. PC suggests that an individual's placement of a cut-off point for retreatment on the health continuum to a large extent is dependent on the agent's personal values. In the present study value judgements (utilities) concerning two periapical health states in endodontically treated teeth were investigated among 82 dental students. The two methods used to elicit utilities, a Visual Analogue Scale (VAS) and the Standard Gamble (SG), produced large inter- and intra-individual variations. VAS frequently generated lower utility values. The results obtained in the study satisfy a necessary criterion for the validity of PC and strengthen the position of the theory.

Microbiological status of root-filled teeth with apical periodontitis. Int Endod J 1998; 31:1-7. [PMID: 9823122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/09/2023]
Abstract
The present study examined the microbiological status of 100 root-filled teeth with radiographically verified apical periodontitis--the pathology (P) group--and of 20 teeth without signs of periapical pathosis--the technical (T) group. In the P group 117 strains of bacteria were recovered in 68 teeth. In most of the cases examined one or two strains were found. Facultative anaerobic species predominated among these isolates (69% of identified strains). Growth was classified as 'sparse' or 'very sparse' in 53%, and as 'heavy' or 'very heavy' in 42%. Enterococci were the most frequently isolated genera, showing 'heavy' or 'very heavy' growth in 25 out of 32 cases (78%). In 11 teeth of the T group no bacteria were recovered, whilst the remaining nine yielded 13 microbial strains. Eight of these grew 'very sparsely'. It is concluded that the microflora of the obturated canal differs from that found normally in the untreated necrotic dental pulp, quantitatively as well as qualitatively. Nonsurgical retreatment strategies should be reconsidered.

Abstract
The large variations observed in dentists' management of periapical lesions in endodontically treated teeth suggest that disease concepts used in clinical practice should be investigated. In the present study it was hypothesized that dentists regard various periapical conditions as different stages on a health continuum. Variations could then be regarded as the result of the individuals selection of differing cut-off points for prescribing retreatment. The hypothesized decision-making model was tested using dental students in Amsterdam (Holland), Gothenburg (Sweden) and Pavia (Italy). The students were shown six simulated cases among which the quality of root filling seal and presence of post and crown were systematically varied. For each case, management of five periapical conditions was assessed. Five options were offered: no therapy, wait-and-see, nonsurgical retreatment, surgical retreatment, and extraction. For each examiner and case a 'retreatment preference score (RPS)' was established. The investigation showed large interindividual variations in RPS. A statistically significant higher mean RPS was seen among students in Pavia compared with students in Amsterdam and Gothenburg. Among all observers and cases it was found that if retreatment was proposed for a certain size of lesion, retreatment was subsequently selected for all larger lesions. The experiment gave evidence in support of the proposed hypothesis. The data also suggest that the choice of retreatment criterion is affected by values, costs of retreatment and technical quality of the original treatment.

Abstract
This study was concerned with the relation between technical quality of root filling seal in teeth with posts and radiographic status of the periapical tissues. Full-mouth series from 298 randomly chosen patients were examined by two observers. Endodontic treatment had been performed in 852 roots and posts were observed in 424 of these. Periapical radiolucencies were judged to be present in 16% of roots with posts and in 13% of roots without posts. Roots with posts in which the remaining root filling was shorter than 3 mm showed a statistically significant higher frequency of periapical radiolucencies (p less than 0.01). It was found that an improper seal was more unfavorable in roots with posts (p less than 0.05). The findings in this study indicate that the placement of a post will not per se decrease the probability of periapical healing. It also suggests that the remaining root filling must not be shorter than 3 mm.
