Clinical and radiographic assessment of post-treatment endodontic disease by primary healthcare professionals: A hospital-based 1-year follow-up. J Family Med Prim Care 2022; 11:1114-1118. [PMID: 35495841 PMCID: PMC9051704 DOI: 10.4103/jfmpc.jfmpc_2033_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2020] [Revised: 12/02/2020] [Accepted: 09/17/2021] [Indexed: 11/29/2022] Open
Abstract
Background: The comprehensive healthcare approach including prophylactic guidance and motivation by the primary healthcare professionals towards oral and maxillofacial diseases such as post-treatment endodontic disease (PTED) plays a significant role in diagnosing and managing the condition. Especially in the developing countries like India where the hygiene practices are severely compromised, the primary healthcare professional plays an upfront role. Objectives: The present study was conducted to assess the clinical and radiographic characteristics of PTED by primary healthcare professional. Materials and Methods: The cross-sectional study was conducted in a dental hospital in Kutch, Gujarat, India. In the present study, out of a total of 755, 96 patients were diagnosed with PTED, met the inclusion criteria, and were enrolled for the study. After performing intraoral and extraoral examination, intraoral periapical radiographs were taken of the concerned teeth. Under dark room conditions, radiographs were examined using dentsply light box and magnifying glass by healthcare professionals. Results: Out of 755 patients, 96 (12.71%) patients were enrolled in the study with 98 concerned teeth. The most common teeth diagnosed with PTED were maxillary molars with 25.51% (21) individuals. Well-defined radiolucent lesions were seen in 62.24% (61) individuals. Voids in both coronal and apical region were seen in majority (38.77%) of patients. The length of root-end fillings with respect to the radiographic apex was satisfactory in 44.89% (44) individuals. The present study showed strong correlation between sinus formation and presence of periapical lesion with P value of 0.0219*. Conclusion: The proper guidance and preventive care by primary healthcare professionals leads to the relatively less prevalence of post-treatment endodontic disease in Indian population. The present study further suggests the higher substandard quality of root-end fillings of endodontically treated teeth.

Abstract
Objective: Apical periodontitis develops when bacteria, or their by products, migrate from the infected root canal system space to the surrounding apical tissues. The objective of the present multi-center cross-sectional study was to analyze the prevalence of lateral radiolucency, apical root resorption and periapical lesions in 7 districts of Portugal using cone-beam computed tomographic (CBCT) assessment. Methods: A total of 1,249 CBCT scans, from 11 dental clinics, were screened. Data regarding 22,899 teeth was included. For each tooth the recorded data was the presence of lateral radiolucency, apical root resorption, periapical lesions, previous root canal treatment, missed root canals, length of root canal filling (short, good or overfilling) and type of coronal restoration (intact tooth, non-restored, filling or crown). Differences between districts were tested using chi-squared. A P<0.05 was considered significant. Results: The proportion of lateral radiolucency ranged between 0.0% (Aveiro, Braga and Coimbra) and 0.9% (Lisbon), while the prevalence of apical root resorption ranged from 0.0% (Braga and Coimbra) to 3.0% in Setubal. The nationwide proportion of lateral radiolucency was 0.4%, while for apical root resorption was 1.1%. The prevalence of periapical lesions varied from 4.1% (Braga) and 13.0% (Lisbon) with a nationwide proportion of 10.0%. Significant differences were noted between districts (P<0.05). Conclusion: The prevalence of lateral radiolucency and apical root resorption were low in all districts. Root canal filled teeth were associated with higher periapical lesions proportions than non-treated teeth. Independently of the assessed district, the periapical status may be influenced by both quality of the endodontic treatment and coronal restoration.

Abstract
BACKGROUND Apical periodontitis (AP) frequently presents as a chronic asymptomatic disease. To arrive at a true diagnosis, in addition to the clinical examination, it is mandatory to undertake radiographic examinations such as periapical or panoramic radiographs, or cone-beam computed tomography (CBCT). Thus, the worldwide burden of AP is probably underestimated or unknown. Previous systematic reviews attempted to estimate the prevalence of AP, but none have investigated which factors may influence its prevalence worldwide. OBJECTIVES To assess: (i) the prevalence of AP in the population worldwide, as well as the frequency of AP in all teeth, nontreated teeth and root filled teeth; (ii) which factors can modify the prevalence of AP. METHODS A search was conducted in the PubMed-MEDLINE, EMBASE, Cochrane-CENTRAL, LILACS, Google scholar and OpenGrey databases, followed by hand searches, until September 2019. Cross-sectional, case-control and cohort studies reporting the prevalence of AP in humans, using panoramic or periapical radiograph or CBCT as image methods were included. No language restriction was applied. An adaptation of the Newcastle-Ottawa Scale was used to evaluate the quality of the studies. A meta-analysis was performed to determine the pooled prevalence of AP at the individual level. Secondary outcomes were the frequency of AP in all teeth, nontreated teeth and rootfilled teeth. Subgroup analyses using random-effect models were carried out to analyse the influence of explanatory covariables on the outcome. RESULTS The search strategy identified 6670 articles, and 114 studies were included in the meta-analysis, providing data from 34 668 individuals and 639 357 teeth. The prevalence of AP was 52% at the individual level (95% CI 42%-56%, I2 = 97.8%) and 5% at the tooth level (95% CI 4%-6%; I2 = 99.5%). The frequency of AP in root-filled teeth and nontreated teeth was 39% (95% CI 36%-43%; I2 = 98.5%) and 3% (95% CI 2%-3%; I2 = 99.3%), respectively. The prevalence of AP was greater in samples from dental care services (DCS; 57%; 95% CI 52%-62%; I2 = 97.8%) and hospitals (51%; 95% CI 40%-63%; I2 = 95.9%) than in those from the general population (GP; 40%; 95% CI 33%-46%; I2 = 96.5%); it was also greater in people with a systemic condition (63%; 95% CI 56%-69%, I2 = 89.7%) compared to healthy individuals (48%; 95% CI 43%-53%; I2 = 98.3%). DISCUSSION The subgroup analyses identified explanatory factors related to the variability in the prevalence of AP. However, the high clinical heterogeneity and high risk of bias across the primary studies indicate that the findings must be interpreted with caution. CONCLUSIONS Half of the adult population worldwide have at least one tooth with apical periodontitis. The prevalence of AP is greater in samples from the dental care services, but it is also high amongst community representative samples from the general population. The present findings should bring the attention of health policymakers, medical and dental communities to the hidden burden of endodontic disease in the population worldwide.

Clin Oral Investig 2021; 25:3937-3944. [PMID: 33404762 DOI: 10.1007/s00784-020-03723-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 12/01/2020] [Indexed: 12/01/2022]
Abstract
OBJECTIVES To investigate the root canal morphology of mesiobuccal (MB) roots in maxillary first molars, and to assess the presence of a second mesiobuccal canal (MB2) according to the location of the main MB canal. MATERIALS AND METHODS A total of 72 extracted permanent maxillary first molars were collected from dental clinics and were scanned with micro-CT and reconstructed three-dimensionally. The root canal systems were recorded according to Vertucci's classification, and the occurrence of accessory canals was also recorded. The root canal dimensions were measured at the coronal (furcation plane), middle, and apical root levels. The long (D) and short (d) diameters as well as the palatal (P) and buccal (B) distances from the center of the first mesiobuccal canal (MB1) to the root surface were measured, and the ratios of D/d and P/B were calculated. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic accuracy of using the ratio of P/B for predicting the presence of an MB2 canal. The best cut-off point was determined according to the sensitivity and specificity. RESULTS The MB roots most frequently had a type 2-2 root canal with an incidence of 37.5% (27/72), followed by the type 1-1 (23.6%, 17/72) and type 2-1 (16.7%, 12/72) canal forms. Type 1-2 canals were detected only in 5 molars (6.9%), and type 2-1-2 canals were detected in 6 molars (8.3%). The other 5 cases included 1 case of type 1-2-1 canal and 4 cases of triple canals. MB2 canals were detected in 76.4% (55/72) of the total sample teeth. The incidence of accessory canals was 56.9% (41/72). The mean ratio of D/d was generally "greatest to least": coronal level > middle level > apical level for different root levels and MB single > MB1 > MB2 for different canals, which reflected a trend from a flat to a circular cross-sectional shape. ROC curve analysis showed that at the coronal and middle root levels, areas under the ROC curve (AUC) were greater than 0.99 (P < 0.01), and the best cut-off point was 1.58 and 1.55, respectively; at the apical level, the AUC was 0.94 (P < 0.01), and the best cut-off point was 1.77. CONCLUSIONS The MB2 canals may be present in the MB roots of maxillary first molars with a high occurrence rate at various levels, and the P/B ratio of the MB1 is a good index for predicting the presence of an MB2. However, since all the sample teeth were collected from a Chinese population, clinicians have to be cautious while trying to apply the conclusions on teeth of other ethnic populations. CLINICAL RELEVANCE By calculating the P/B ratio, an index reflecting the buccal deviation of the MB1, clinicians can predict the presence of an invisible MB2 in cone-beam computed tomography images with inadequate resolution.

Abstract
Aim It is the aim of this paper to consider whether overall patient treatment history per se and what length of patient history, matters in predicting future treatment need.Methods This study used a data set (SN7024, available from UKDataService), consisting of treatment records for General Dental Services' (GDS) patients, this being obtained from all items of service payment records for patients treated in the GDS of England and Wales between 1990 and 2006. For the purpose of this study, the GDS dataset for patients attending in 2003 was restricted to adult patients (aged 18 or over on 31 December 1990; that is, year of birth earlier than 1973) who attended in both two-year periods 1991/2 and 2004/5. Each course of treatment was classified as 'active' (eg restoration, extraction, prosthesis) or 'not active' (eg prevention, diagnosis). Treatment costs for 2001-2005 (outcome), 2000 (one-year history), 1999-2000 (two-year history) and so on until 1991-2000 (ten-year history) were determined, and history and outcome correlated.Results A total of 455,844 patients met the inclusion criteria, namely adults with a full history. They received 9,341,583 courses of treatment, of which 49% were classified as 'active' and 51% as 'not active'. The analysis indicated that both total costs and active treatment costs are positively correlated with their historical values, with the correlation coefficients increasing from 0.24 and 0.25 with one year of history to 0.42 and 0.44 with ten years of history. Overall, therefore, future treatment cost is correlated with past treatment costs.Conclusions Treatment history may provide an important correlate of future dental treatment needs and the more history the better, at least up to five years. However, active treatment is the important component and should be distinguished from preventive and diagnostic treatments.

Abstract
The aim of this study was to investigate the post-treatment apical periodontitis in endodontically treated teeth related to the technical quality of root fillings and restorations in Thai population. Full-mouth periapical radiographs from Thai patients attending the Faculty of Dentistry, Mahidol University, Thailand were examined. The periapical status, quality of root fillings and coronal restorations, existence of intraradicular post and its relationship to the root fillings were evaluated. Among 1586 patients, 37.4% presented endodontically treated teeth. The total number of endodontically treated teeth was 1511, and 35% presented apical periodontitis. Combined data for root filling and coronal restoration qualities revealed significantly better outcome in teeth with adequate qualities of both parameters than the other combinations (P < 0.001). The prevalence of post-treatment apical periodontitis among Thai population was relatively high and significantly associated with substandard technical quality of root fillings and restorations.

Abstract
Detonation nanodiamonds (NDs) are promising drug delivery and imaging agents due to their uniquely faceted surfaces with diverse chemical groups, electrostatic properties, and biocompatibility. Based on the potential to harness ND properties to clinically address a broad range of disease indications, this work reports the in-human administration of NDs through the development of ND-embedded gutta percha (NDGP), a thermoplastic biomaterial that addresses reinfection and bone loss following root canal therapy (RCT). RCT served as the first clinical indication for NDs since the procedure sites involved nearby circulation, localized administration, and image-guided treatment progress monitoring, which are analogous to many clinical indications. This randomized, single-blind interventional treatment study evaluated NDGP equivalence with unmodified GP. This progress report assessed one control-arm and three treatment-arm patients. At 3-mo and 6-mo follow-up appointments, no adverse events were observed, and lesion healing was confirmed in the NDGP-treated patients. Therefore, this study is a foundation for the continued clinical translation of NDs and other nanomaterials for a broad spectrum of applications.

Abstract
AIM To assess the prevalence of apical periodontitis (AP) and the technical quality of root canal treatment in an adult sub-population in London. METHODOLOGY Panoramic radiographs of 136 patients who attended a dental hospital were collected. The periapical health of teeth present was assessed radiographically and the presence or absence of AP noted. The technical quality of the root canal treatment was scored as adequate or inadequate, based on the European Society of Endodontology (2006) guidelines. RESULTS A total of 3,396 teeth were assessed; AP was detected in 4.1% of the teeth. Forty-nine percent of patients had at least one tooth with radiographic evidence of AP. The percentage of root filled teeth with AP was 38.3%. AP was significantly more frequently found in root treated, compared with non-root treated, teeth (p <0.001). In 44.3% of the cases, the technical quality of the root canal filling was inadequate. AP was detected in 14% of adequately, compared with 68.6% of inadequately, root filled teeth. There is a significant negative correlation between the technical quality of root canal treatment and the presence of AP (p <0.001). CONCLUSIONS There was a high prevalence of AP and poor technical quality root canal treatment; a strong association between AP and root filled teeth, and between the periapical health and the technical quality of the root canal treatment. The results are consistent with previous studies using similar methodology and re-confirmed that high technical quality root canal treatment is crucial to ensure a favourable treatment outcome.

Abstract
INTRODUCTION The objective of this study was to investigate the association between chronic apical periodontitis (CAP) and low-birth-weight preterm births (LBWPB). METHODS Sixty-three women in postpartum period were included in this case-control study. The case group consisted of mothers of LBWPB infants (n = 33), and the control group was represented by mothers of newborns at term (n = 30). The CAP diagnosis was performed by using periapical radiographs through the periapical index in postpartum period. The χ(2) test, Fisher exact test, and linear and logistic regression were used for statistical analysis. RESULTS It was observed that CAP was present in 54.5% of mothers in the case group and 20.0% in the control group (P = .004); postpartum women with CAP had about 3.5 times greater odds of LBWPB newborns than women without CAP (adjusted odds ratio, 3.52; 95% confidence interval, 1.01-12.32). Postpartum women who reported 6 or more prenatal consultations reduced odds of LBWPB newborns in 80% (adjusted odds ratio, 0.20; 95% CI, 0.06-0.69). It can be estimated that the increase of 1 unit of periapical index had a significant association with the reduction of 1½ gestational weeks in the crude analysis (β = -1.5, P = .010) and the reduction of 211 g in birth weight after the adjusted analysis (β = -211, P = .058). CONCLUSIONS Prematurity and low birth weight were associated with radiographically detected CAP. Women with CAP in postpartum period had greater odds of LBWPB.

Abstract
Apical periodontitis (AP) develops as a result of the host’s immune inflammatory response to pulpal infection of the dental root canals that leads to the generation of an apical lesion of endodontic origin (ALEO) and potentially to systemic metabolic alterations. Misdiagnosed ALEO is not infrequent due to the lack of diagnostic tools to differentiate apical lesions of different natures. Despite the conservative endodontic treatment shows a high success rate, there are refractory cases that can not be identified early enough during follow up. This evidences the need to develop complementary diagnostic tools, such as oral fluid biomarker analysis. Gingival crevicular fluid (GCF) is a serum transudate that becomes an exudate under inflammatory conditions, carrying molecules from local periodontal tissues and general circulation than can be harvested non-invasively. We aimed to review the available literature analyzing GCF composition in AP patients to evaluate whether GCF has any potential for complementary diagnosis. To the date, only few studies addressing changes of GCF components in AP are available. Most studies support GCF modifications in specific components in AP-affected teeth, suggesting that it might reflect periapical inflammation. GCF has potential for diagnostic tool, treatment follow-up and eventually to assess systemic comprise.

Abstract
OBJECTIVE This article discusses the relationship between apical limit of root canal filling and success on endodontic treatment of a mandibular molar. STUDY DESIGN A mandibular right first molar with vital pulp was endodontically treated, and 3 years later periapical lesions on mesial and distal roots were detected. The canals were retreated and obturated to the same levels as in the previous treatment. RESULTS An 8-year radiographic follow-up showed repair of the periapical lesions on both roots. CONCLUSIONS Results suggest that the apical limit of obturation seems to have no influence in the repair of periapical tissues in mandibular molars.
