Low serum progesterone on day of transfer adversely impacts ongoing pregnancy rates in hormonally prepared single blastocyst frozen embryo transfer cycles.

OBJECTIVE: To evaluate if serum progesterone (P) levels on the day of transfer influence ongoing pregnancy rate (OPR) in hormonally prepared single blastocyst frozen embryo transfer (FET) cycles? STUDY DESIGN: Single center prospective cohort study conducted between June 2021 and August 2022 analyzed 217 single good quality blastocyst FET cycles hormonally prepared with oral estradiol valerate and micronized vaginal progesterone 400 mg twice daily. RESULTS: Mean serum P on the day of embryo transfer (ET) was 9.76 ± 5.19 ng/ml. Receiver operator curve (ROC) showed a significant predictive value of serum P levels on the day of ET for OPR, with an area under curve (AUC) (95 %CI) = 0.58 (0.49-0.66). Optimal serum P threshold for OPR was 7.7 ng/ml (Sensitivity 76.8%, Specificity 43.7%). 35.9% patients had serum P below this threshold. BMI was significantly higher (26.8 ± 3.7 vs 25.6 ± 4.3; p = 0.048) in patients with serum P < 7.7 ng/ml vs ≥ 7.7 ng/ml. OPR was significantly lower (24.4% vs 45.3%; p = 0.002) and clinical miscarriage rates significantly higher (37.9% vs 19.2%; p = 0.042) if serum P < 7.72 ng/ml vs ≥ 7.7 ng/ml. CONCLUSION: This study found that serum P level on the day of transfer in hormonally prepared FET cycles was a significant predictor of OPR.

Association of Apical Periodontitis with Different Stages of Chronic Kidney Disease Measured by Glomerular Filtration Rate and Systemic Markers: An Observational Study.

INTRODUCTION: The aim of this study was to assess the prevalence and severity of apical periodontitis (AP) in subjects with different stages of chronic kidney disease (CKD) and its association with systemic markers. METHODS: In this cross-sectional study, 105 patients with CKD (n = 35 each in the early, predialysis, and hemodialysis groups) and 105 healthy controls were included. The prevalence, number of teeth with AP (endodontic burden [EB]), and the severity of AP were recorded. High- sensitivity C-reactive protein, blood urea, and serum creatinine levels were also recorded. Logistic regression was applied to determine the possible association between CKD and AP in the study population, and linear regression was performed to predict the effect of AP on systemic markers in CKD patients. RESULTS: AP in at least 1 tooth was found in 75.2% of CKD patients and 40.9% of the controls (P < .05). CKD patients were 4 times more likely to have AP than controls (P < .05; odds ratio = 3.954; 95% confidence interval, 2.09-7.45). EB and the severity of AP were also significantly higher in CKD patients than the healthy controls (P < .05). Although higher values of EB and severe AP were observed with the progression of disease, the difference was not significant. The severity of AP was significantly associated with an increase in serum creatinine, blood urea, and a decrease in estimated glomerular filtration rate (P < .05) in CKD patients. CONCLUSIONS: AP was significantly more prevalent in the CKD group. The association between the severity of AP and CKD markers suggests that AP could possibly alter the progression of CKD. However, these findings do not establish a cause-and-effect relationship.

Effect of endodontic treatment on endothelial dysfunction and subclinical atherosclerosis-a prospective intervention study.

OBJECTIVE: The objective of this study is to investigate the effect of endodontic treatment on flow-mediated dilatation (FMD) and carotid intima-media thickness (c-IMT) in patients with apical periodontitis (AP). MATERIAL AND METHOD: The study includes 32 young men having AP with a mean age of 25.78 years free from cardiovascular disease (CVD) and its risk factors, including periodontitis. All subjects underwent complete physical and dental examination, echocardiography, and ultrasound assessment of FMD on the brachial artery and c-IMT on the carotid artery at baseline and 12 months after the endodontic treatment. Data were analyzed using paired Student's t-test and Pearson's correlation coefficient (r) test using SPSS 26 version. RESULTS: Endodontic treatment leads to the improvement of FMD significantly from a pooled baseline value of 4.84 ± 1.55% to 7.68 ± 2.08% (p < 0.05). The study also depicts a statistically significant difference between c-IMT (mean = 0.62 ± 0.11 mm) before treatment as compared to 12 months after treatment (mean = 0.59 ± 0.11 mm) (p < 0.05). CONCLUSION: Endodontic treatment leads to improved FMD and decreased c-IMT suggesting that treating AP can be help revert the early stages of CVD. CLINICAL RELEVANCE: AP could be a potential etiological factor of future CVD and should be treated as soon as diagnosed.

Comparative histological evaluation of two PRF formulations (PRF High and PRF Medium) on quality of life and healing outcome of apicomarginal defects: A randomized clinical trial.

The objective of this randomized clinical trial was to investigate the effects of two PRF formulations (PRF High and PRF Medium) on quality of life and healing outcome (2D and 3D) of apicomarginal defects. Patients presenting with endodontic lesions and concomitant periodontal communication were randomly allocated to PRF High and PRF Medium groups. The treatment protocol in each group included a periapical surgical procedure with placement of PRF clot and membrane in the bony defect and on the denuded root surface, respectively. Quality of life was assessed for 1 week after surgery following a modified version of the patient's perception questionnaire. Postoperative pain was assessed using a visual analog scale. Clinical and radiographic evaluations were performed using Rud and Molven 2D criteria and Modified PENN 3D criteria. Buccal bone formation was assessed using sagittal and corresponding axial sections in CBCT. Histological analysis was performed using hematoxylin and eosin (H and E) staining and attaching primary antibodies to tissue sections. In total, 40 patients were enrolled in the trial (N = 20 per group). PRF Medium group patients reported significantly less swelling on the 1st (p = 0.036), 2nd (p = 0.034), and 3rd (p = 0.023) days, and average pain on the 2nd (p = 0.031), 3rd (p = 0.03), and 4th (p = 0.04) days postoperatively. The difference in success rate for periapical healing was non-significant between the PRF Medium group (89.5%) and PRF High group (90%), in both 2D and 3D imaging (p = 0.957). The formation of buccal bone was observed in five cases (26.3%) and four cases (20%) in the PRF Medium and PRF High groups, respectively, with a non-significant difference (p = 0.575). PRF Medium clots had a loose fibrin structure with a significantly higher number of neutrophils (473.79 ± 82.89 per mm2) than PRF High clots, which had a dense structure and fewer neutrophils (253.15 ± 63.86 per mm2) (p = 0.001). Autologous platelet concentrates (APCs) promoted satisfactory periapical healing, with no significant difference between the groups. Within the limitations of the study, it seems that PRF Medium should be preferred over PRF High when the patients' quality of life is the priority.

Ipsilateral Salpingopexy in a Case of Isolated Tubal Torsion.

Isolated fallopian tube torsion (IFTT) is a rare emergency condition affecting young females. Due to the diagnostic dilemma, diagnosis of IFTT is often delayed leading to tubal necrosis and salpingectomy as the only choice of treatment. If diagnosed early, it can be managed conservatively by detorsion. Salpingopexy is an option described in the literature to prevent recurrence of this condition; however, evidence is scarce. This case report highlights the role of prompt diagnosis and management of IFTT. It describes a case of IFTT with paratubal cysts and a long tube in a young female, which was timely diagnosed and managed conservatively by laparoscopic detorsion, paratubal cystectomy, and ipsilateral salpingopexy.

Patient-centric outcome assessment of endodontic microsurgery using periapical radiography versus cone beam computed tomography: A randomized clinical trial.

AIM: This study aimed to evaluate whether utilizing additional cone beam computed tomography (CBCT) imaging has any effect on quality of life and healing outcome following periapical surgery compared with periapical radiographs (PR). METHODOLOGY: The study was registered in ClinicalTrials.gov (NCT04333940). In this parallel group randomized controlled trial, 52 patients (88 teeth) with persistent apical periodontitis and periapical radiographic evidence of periapical lesion were randomly assigned to either PR or CBCT group. The primary predictor was the type of the imaging method (PR only or with additional CBCT). The primary outcome was patient's quality of life during the first week after periapical surgery and the secondary outcomes were duration of surgery and healing outcome at 12-month follow-up. Participants of both groups received periapical surgery based on the pre-surgical plan provided by the radiographic imaging methods. Quality of life (QoL) was assessed using Modified Shugars questionnaire. Radiographic analysis for healing was conducted using Molven's criteria and modified PENN 3D criteria. The categorical data between groups were analysed using the Chi-square test, whilst intragroup comparisons were analysed using the McNemar test. The average scores for each component of QoL (oral functions, general functions, pain, swelling and other symptoms), combined QoL scores (overall average of values of 13 variables) and analgesic usage on each day were calculated and analysed. RESULTS: At 12 months of follow-up, fifty patients were evaluated. Participants in PR group reported significantly more swelling on first three days compared with CBCT group. The analgesic use was higher in the PR group on 2nd and 3rd day (Mann-Whitney U test with Bonferroni correction; p < .007). A significant difference in the limitation of general functions was observed at the second day (p < .07) with the higher values in the PR group. The combined QoL score between the two groups was found to be non-significant. However, none of the patients experienced intraoperative complications or neurovascular exposure. The mean surgical time was lesser in the CBCT group (p < .05). Radiographic healing revealed a success rate of 96.2% for the PR group and 95.8% for the CBCT group with no significant difference between the groups. CONCLUSION: Participants in the CBCT group experienced substantially less early postoperative swelling and limitation in general functions, in comparison with the PR group. However, preoperative CBCT had no effect on other QoL parameters and intraoperative complications in medium-risk patients. Furthermore, CBCT did not exhibit any added advantage over periapical radiography in terms of assessing healing outcome following endodontic microsurgery. CBCT offered surgically relevant anatomic information for pre-surgical planning and ensured the treatment rendition with a significantly reduced operative time.

An Overview of Green Synthesis and Potential Pharmaceutical Applications of Nanoparticles as Targeted Drug Delivery System in Biomedicines.

Nanotechnology-based nanomedicine offers several benefits over conventional forms of therapeutic agents. Moreover, nanomedicine has become a potential candidate for targeting therapeutic agents at specific sites. However, nanomedicine prepared by synthetic methods may produce unwanted toxic effects. Due to their nanosize range, nanoparticles can easily reach the reticuloendothelial system and may produce unwanted systemic effects. The nanoparticles produced by the green chemistry approach would enhance the safety profile by avoiding synthetic agents and solvents in its preparations. This review encompasses toxicity consideration of nanoparticles, green synthesis techniques of nanoparticle preparation, biomedical application of nanoparticles, and future prospects.

Evaluation of amniotic membrane in the healing of apicomarginal defects using 2D and 3D imaging modalities: a randomized controlled trial.

OBJECTIVE: The study aimed to evaluate healing in apicomarginal defects with amniotic membrane (AM) using 2D periapical radiography and 3D cone beam computed tomography imaging. METHOD AND MATERIALS: Thirty-four patients with symptomatic apical periodontitis and apicomarginal communication were allocated to either the AM or control group. Clinical and radiographic assessment was performed at baseline and at 12 months using Molven criteria, modified Penn 3D criteria, and RAC and B indices at resected plane, apical area, cortical plate, and combined apicocortical area, respectively. RESULTS: There was no significant difference in the healing outcome in 2D imaging (93.3% control and 86.7% AM) and 3D imaging (80.0% control and 53.3% AM) between the groups. With RAC scoring, a greater percentage of unhealed cases was observed in cortical plate. Radiographic buccal bone formation in the 3D imaging was evident only in six cases. However, both the groups depicted significantly greater percentage reduction in the size of the lesion in 2D than the 3D analysis (AM group 91.69 ± 15.99 2D, 76.06 ± 47.62 3D, P = .020) and (control group 92.06 ± 14.36 2D, 85.12 ± 18.55 3D, P = .005). CONCLUSION: No significant difference in healing was observed between the AM and the control groups with the use of both periapical radiography and CBCT imaging. Despite good clinical healing and radiographic apical bone fill, buccal bone formation was not evident in 3D imaging in most of the cases.

Comparative evaluation of complete and partial pulpotomy in mature permanent teeth with symptomatic irreversible pulpitis: A randomized clinical trial.

AIM: The study aimed to compare the outcome of complete pulpotomy (CP) and partial pulpotomy (PP) techniques when utilised for the management of mature permanent teeth with carious pulpal exposure and symptomatic irreversible pulpitis (SIP). METHODOLOGY: The study protocol was registered with ClinicalTrials.gov (NCT04397315). One hundred and six permanent mandibular molars with carious pulpal exposure and clinical diagnosis of SIP with periapical index ≤2, from patients aged between 18 and 40 years were randomly allocated in equal proportion to either CP or PP group. Allocated procedures were performed using standardised protocols. The allocated procedure was abandoned in cases where pulpal bleeding could not be controlled within 6 min using cotton pellets soaked in 3% sodium hypochlorite. MTA was used as a pulpotomy agent and teeth were restored using a base of glass ionomer followed by composite restoration. The pain was recorded by the patient preoperatively before administration of local anaesthesia and postoperatively every 24 h for 1 week using visual analogue scale. Success was analysed at 12 months based on clinical and radiographic examination. Mann-Whitney U test was used to compare age, pain scores and mean analgesic consumption between the groups. Categorical data were analysed using chi-square test. Fisher's exact test was used to assess the clinical and radiographic success and incidence of pain. Kaplan-Meier analysis was used to assess the survival of teeth. A p-value <.05 was considered as statistically significant. RESULTS: One hundred and one patients were analysed at follow up. Higher success was observed in CP (89.8%) in comparison to PP group (80.8%), but the difference was non-significant statistically (p = .202). Although no significant difference was observed in pain incidence between the groups at 24 h (p = .496), a significant difference in pain intensities was observed between groups at all the tested time intervals, with lower values reported in CP group (p < .05). CONCLUSIONS: Both CP and PP resulted in favourable outcomes in the management of cariously exposed permanent teeth with signs indicative of SIP. Given the more conservative nature of PP, it may be attempted first before proceeding to CP in such cases.

Service user experiences of care recommendations from the 2014 NICE guideline for bipolar disorder: a survey.

Clinical guidelines for mental health disorders produced by the National Institute of Care Excellence (NICE) emphasise a recovery-based approach clinical care with collaborative decision-making. The aim of the study was to explore service user experience of collaborative decision-making and recovery focussed care in relation to a NICE clinical guideline for bipolar disorder four years after publication. Participants with a clinical diagnosis of bipolar disorder were recruited from adult mental health services in four specialist mental health NHS Trusts through health professional or self-referral following advertisement. An online or written survey was designed with service user input to cover 40 NICE recommendations on recovery based or collaborative care. Participants completed the survey anonymously and independent of any health professional involvement. Of 222 participants, 72 (33.5%) reported to a great extent care was delivered in line with a positive recovery message; 55 (25.5%) reported that not much or no care was recovery based. Only four items (10%) on medication or the offer of crisis services were endorsed as collaborative decision-making with a health professional by >70% service users. Most decision-making in relation to the NICE clinical guideline for bipolar disorder was not delivered collaboratively and only some care was recovery focussed.

Large Interstitial Ectopic Pregnancy: Management by Laparoscopic Cornuostomy Following Initial Misdiagnosis.

The purpose of the present report is to highlight the challenges in diagnosing interstitial ectopic pregnancy and to describe its management by laparoscopic cornuostomy. A 28-year-old gravida 3, para 1 woman was referred to us at 12 weeks period of gestation after failed medical termination following a diagnosis of missed abortion. On presenting to us, a large interstitial ectopic pregnancy was diagnosed by ultrasonography and managed by laparoscopic cornuostomy. Intra myometrial vasopressin and purse string sutures at the base of ectopic pregnancy bulge were used to reduce intra-operative bleeding. Intra-operative blood loss was 50 ml. Patient was discharged after two days of surgery. Interstitial pregnancy may be misdiagnosed as an intrauterine pregnancy, due to lack of suspicion and expertise. Large interstitial ectopic pregnancies can be successfully managed by a conservative surgical approach such as laparoscopic cornuostomy instead of cornual resection or hysterectomy.

Trends in referrals to liaison psychiatry teams from UK emergency departments for patients over 65.

INTRODUCTION: The number of people over the age of 65 attending Emergency Departments (ED) in the United Kingdom (UK) is increasing. Those who attend with a mental health related problem may be referred to liaison psychiatry for assessment. Improving responsiveness and integration of liaison psychiatry in general hospital settings is a national priority. To do this psychiatry teams must be adequately resourced and organised. However, it is unknown how trends in the number and type referrals of older people to liaison psychiatry teams by EDs are changing, making this difficult. METHODS: We performed a national multi-centre retrospective service evaluation, analysing existing psychiatry referral data from EDs of people over 65. We described trends in the number, rate, age, mental health presentation, and time taken to assessment over a 7 years period. RESULTS: Referral data from 28 EDs across England and Scotland were analysed (n = 18,828 referrals). There was a general trend towards increasing numbers of people referred to liaison psychiatry year on year. Variability in referral numbers between different departments, ranged from 0.1 to 24.3 per 1000 ED attendances. The most common reasons for referral were mood disorders, self-harm and suicidal ideas. The majority of referrals were assessed within 60 min, however there is variability between departments, some recording waits over 11 h. DISCUSSION: The data suggests great inter-departmental variability in referral numbers. Is not possible to establish the cause of variability. However, the data highlights the importance of asking further questions about why the differences exist, and the impact that has on patient care.

Comparative analysis of the accuracy of periapical radiography and cone-beam computed tomography for diagnosing complex endodontic pathoses using a gold standard reference - A prospective clinical study.

AIM: To compare the diagnostic accuracy of periapical radiography (PR) and cone-beam computed tomography (CBCT) for detecting pathoses of endodontic origin using the gold standard of direct surgical visualization. METHODOLOGY: Seventy-four patients (112 teeth) underwent radiographic examination by periapical radiography and CBCT. The presence of periapical lesions, root perforations and their locations, root fractures, different types of external root resorptive defects, apicomarginal bone defects, through and through bone defects, buccal bone status and proximity of root apices and lesions to vital anatomical structures were assessed. These same parameters were assessed intraoperatively by direct surgical visualization which served as the gold standard reference for the radiographic assessments. Sensitivity, specificity, positive predictive values, negative predictive values were determined for comparison of diagnostic accuracy between two modalities. RESULTS: There were no significant differences between the two imaging modalities for root resorptive defects and root fractures. However, CBCT accurately detected periapical lesions, root perforations, apicomarginal bone defects and through and through bone defects. The overall accuracy of CBCT varied from 91% to 96% in detecting dehiscence and fenestration of buccal cortical plates. CONCLUSION: Overall, CBCT had a higher diagnostic accuracy in complex endodontic pathoses compared to PR. Nevertheless, CBCT failed to diagnose apicomarginal bone defects in 33% teeth. In evaluating the status of buccal cortical plate from CBCT images, observers could detect absence of bone better than its presence. Thus, limited FOV CBCT should be considered for selective cases where periapical radiography has diagnostic ambiguity.

Effect of the Piezoelectric Device on Intraoperative Hemorrhage Control and Quality of Life after Endodontic Microsurgery: A Randomized Clinical Study.

INTRODUCTION: The purpose of this study was to evaluate the effect of the piezoelectric device on intraoperative hemorrhage control during surgery and the quality of life of patients after endodontic microsurgery. METHODS: A total of 40 patients were randomly divided into the piezo group (n = 20) and the control group (n = 20). In the piezo group, after flap reflection, bone cutting, granulation tissue removal, and root-end resection were performed using the piezoelectric surgical device and surgical carbide burs, and curettes were used in the control group. The quality of life of patients was evaluated daily for 1 week postsurgery for limitations of oral and general functions, pain, and other symptoms. Limitation of functions and other symptoms were recorded by a modified version of the patient's perception questionnaire using a 5-point Likert scale for mouth opening, chewing, speaking, sleeping, daily routine, missed work, swelling, nausea, and bad taste/breath, and the visual analog scale was adopted for pain. Hemorrhage control during surgery was independently assessed by the surgeon and 2 blinded observers and recorded as 0 (no hemorrhage control), 1 (intermittent control), and 2 (complete control). The chi-square test was used to assess hemorrhage control. For variables related to function and symptoms other than pain and analgesics taken, the Fisher exact test was used. For the assessment of pain between the 2 groups, the Mann-Whitney U test was used. RESULTS: For parameters of quality of life, the piezo group showed significantly less swelling on the first, second, and third days and pain on the first and second days compared with the control group (P < .05). Analgesics taken were also significantly less in the piezo group (P < .05). In the piezo group, complete hemorrhage control was achieved in 10 patients, and in the control group, it was achieved only in 1 patient (P < .05). CONCLUSIONS: Piezoelectric surgery resulted in improved quality of life of patients in the first week postsurgery with lower levels of pain and swelling as well as the number of analgesics taken and better hemorrhage control during surgery.

Expression of Ki-67 in early glottic carcinoma and its relation to oncological outcomes following CO2 laser microsurgery.

INTRODUCTION: The behavior of the laryngeal squamous cell carcinoma (LSCC) is marked by the degree of cell proliferation and differentiation. Ki-67 is regarded as a promising proliferation marker and has been correlated as a prognostic indicator. AIM: The aim of the present study is to determine the Ki-67 expression and its prognostic value in LSCC. MATERIALS AND METHODS: A total of eighty patients with early glottic carcinoma stage (Tis, T1, T2) N0 M0 were included. After preoperative workup, surgery was performed using LUMINES 40C CO2 laser and tumor resection was done which was sent for histopathological diagnosis and immunohistochemistry (IHC). IHC for Ki-67 expression could be done only on 65 specimens. RESULTS: All patients had microscopically confirmed squamous cell carcinoma. Forty-eight out of 65 specimens (75%) stained positive for Ki-67 and 17 (25%) stained negative. Out of total 48, 29 stained 2+, 11 stained 3+ and 8 stained 4+. No difference was found in Ki-67 expression in relation to age, sex, T stage, and histological grading. The association of Ki-67 with recurrence was found to be statistically significant. The association of Ki-67 with survival was also studied and Ki-67 positivity is associated with increased mortality rate, although it was not statistically significant. CONCLUSION: The proliferative index as measured by immunohistochemical staining of Ki-67 correlates with the tumor aggressiveness. High Ki-67 index is associated with early relapse and poor survival outcomes.

Impact of Platelet-rich Plasma in the Healing of Through-and-through Periapical Lesions Using 2-dimensional and 3-dimensional Evaluation: A Randomized Controlled Trial.

INTRODUCTION: The purpose of this randomized controlled trial was to evaluate the role of platelet-rich plasma (PRP) in the healing of through-and-through periapical lesions using both 2-dimensional periapical radiographs and 3-dimensional (3D) cone-beam computed tomographic imaging. METHODS: Thirty-four patients after confirmation of a through-and-through periapical lesion were enrolled and randomly assigned to either the control or PRP group. Periapical surgery was performed, and grafting of the bone defect with PRP was done in the PRP group before suturing. Follow-up was scheduled at 12 months for clinical and radiographic analysis based on Molven's criteria; modified Penn 3D criteria; and resected plane, apical area, and cortical plate indexes. The absolute area and volume of the lesions were measured preoperatively and at follow-up using CorelDRAW X7 (64-bit) (Corel Corporation, Ottawa, Canada) and ITK Snap software (free software under the GNU General Public License developed by the National Institutes of Health, the US National Institute of Biomedical Imaging and BioEngineering, the US National Library of Medicine, the Universities of Pennsylvania and North Carolina, and an independent developer group), respectively. RESULTS: Thirty-two patients were available at follow-up. A success rate of 93.7% was observed for both the control and PRP groups on 2-dimensional evaluation, whereas the PRP group exhibited a significantly higher success rate (87.5%) than the control (50%) on 3D assessment. A significantly higher percentage reduction in the lesion volume was documented in the PRP group (92.30 ± 4.72) than the control group (83.04 ± 12.82). Resected plane, apical area, and cortical plate indexes revealed a significantly higher scoring at the resected plane and cortical plate parameter in the PRP group. Overall analysis documented the faster re-establishment of the palatal cortical plate than the buccal cortical plate in through-and-through lesions. CONCLUSIONS: These results suggest that PRP improves the healing outcome in through-and-through lesions. CBCT imaging provides better healing assessment after periapical surgery over periapical radiographs in such lesions.

Effect of Different Liners on Pulpal Outcome after Partial Caries Removal: A Preliminary 12 Months Randomised Controlled Trial.

AIM: The aim of this double-blinded parallel randomised controlled trial was to compare the effect of different liners on 12-month pulp health outcomes after partial caries removal (PCR) with composite restorations in permanent molars. METHODS: The study was registered at clinicaltrials.gov with registration No. NCT0328695 and conducted in the Department of Conservative dentistry and Endodontics, Post Graduate Institute of Dental Sciences Rohtak with no external financial support. One hundred and ninety-eight participants (116 males, 82 females and age 14-54 years) with vital permanent mature mandibular molars having deep caries involving two-thirds or more of dentin were randomised to calcium hydroxide (CH), resin-modified GIC (RMGIC) and no liner (DC) groups after PCR. After a follow-up time of 12 months, success was defined as positive response to pulp sensibility and absence of periapical alterations. RESULTS: Categorical variables were compared using chi-square test. Two analytical approaches were used, such as intention-to-treat and per-protocol approach. Success rates in per-protocol approach were 96.8, 96.5, and 94.6% for CH, RMGIC and DC groups, respectively with no significant difference between 3 groups (p = 0.811). None of the baseline variables had any significant influence on the treatment success. CONCLUSION: Partial caries excavation has a high success rate to treat deep carious lesions in permanent teeth after 12 months of follow-up, indicating that the retention of carious dentin does not interfere with pulp vitality or restoration survival. Also, the success of the treatment is independent of the lining material used over the demineralized dentin.

Association of Apical Periodontitis with Cardiovascular Disease via Noninvasive Assessment of Endothelial Function and Subclinical Atherosclerosis.

INTRODUCTION: Chronic infections of endodontic origin might predispose to the onset of cardiovascular disease (CVD). The studies depicting the link between apical periodontitis (AP) and CVD are few, and the association is very controversial; also, the markers used are expensive, which makes them difficult to use in general practice. The purpose of this study was to investigate whether an association exists between AP and CVD using noninvasive methods (ie, flow-mediated dilatation [FMD] and carotid intima-media thickness [c-IMT]). METHODS: This cross-sectional study included 120 men between 20 and 40 years old free from periodontal disease, CVD, and traditional cardiovascular risk factors; 60 subjects had AP, and 60 acted as controls. All subjects underwent complete physical and dental examination, echocardiography, ultrasound assessment of FMD of the right brachial artery, and c-IMT. Data were analyzed using the Mann-Whitney U test and the Spearman rank correlation (rs) test. RESULTS: FMD was found to be significantly impaired in patients with AP (mean = 4.9% ± 2.05%) compared with healthy controls (mean = 9.74% ± 2.59%, P = .000). The study also depicts statistically significant differences between c-IMT of the AP (mean = 0.64 ± 0.12 mm) and control (mean = 0.54 ± 0.08 mm) groups (P = .000). A significant inverse correlation between c-IMT and FMD was observed (rs = -0.381, P = .000). CONCLUSIONS: Impaired FMD and greater c-IMT in subjects with AP suggests a potential association between endodontic infection and CVD.
