Effect of cyproterone acetate/ethinyl estradiol combination on periodontal status and high-sensitivity C-reactive protein levels in women with polycystic ovary syndrome: a cross-sectional study.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is widely reported among young females, and anti-androgens are used for treating hirsutism and acne in these patients. The protective effects of myo-inositol, oral contraceptives, and insulin sensitizers have been reported on the periodontium and high-sensitivity C-reactive protein (hsCRP) levels in PCOS females. However, cyproterone acetate/ethinyl estradiol (CPA/EE) has not yet been studied. This cross-sectional study explores the periodontal status and systemic inflammation in PCOS women on CPA/EE drug combination compared to females not on medication. METHOD AND MATERIALS: A total of 150 participants were enrolled into three groups: 50 newly diagnosed PCOS females not on medication (N-PCOS); 50 PCOS females consuming CPA/EE combination for the last 6 months (PCOS+CPA/EE); and 50 systemically healthy females (control group). Anthropometric, biochemical, periodontal parameters, and health-related quality of life questionnaires were recorded. RESULTS: N-PCOS and PCOS+CPA/EE groups showed a nonsignificant difference in hsCRP levels, Gingival Index, bleeding on probing, waist circumference, and waist-hip ratio (P > .05). Gingival thickness and keratinized tissue width were significantly greater in the PCOS+CPA/EE than the N-PCOS group (P ≤ .05); however, these were comparable with the control group (P > .05). Regression analysis showed significant association of bleeding on probing with Gingival Index, clinical attachment level, and hsCRP (P ≤ .05). CONCLUSIONS: CPA/EE combination does not influence the periodontal and systemic inflammatory status in PCOS females, as similar levels of local and systemic inflammation were observed in CPA/EE consumers compared with PCOS females not on medication. However, it might play a role in increasing gingival thickness and keratinized tissue width in these patients.

Impact of subgingival instrumentation on systemic inflammation and serum bone resorption marker in premenopausal women with periodontitis: a prospective interventional study.

OBJECTIVES: Inflammatory disorders including periodontitis have been investigated for their impact on systemic inflammation and bone health. The present study was conducted with an aim to evaluate impact of control of periodontal inflammation through subgingival instrumentation on serum interleukin 6 and serum C-terminal telopeptide of type I collagen (CTX) in premenopausal females with stage II and III periodontitis. METHOD AND MATERIALS: In this single-arm prospective study, periodontal parameters, serum interleukin 6, serum CTX, and hematologic parameters (total leukocyte count, differential leukocyte count, platelet count, mean platelet volume, and platelet distribution width) were assessed at baseline. Subgingival instrumentation was done, and oral hygiene instructions were given. At week 4, professional plaque control was performed, and oral hygiene instructions were reinforced. Serum and hematologic parameters were reassessed at 8 weeks after subgingival instrumentation, in individuals meeting the clinical endpoints (ie, bleeding on probing < 10%). RESULTS: There was significant reduction in serum interleukin 6 of 0.168 ± 0.164 pg/mL (P = .000), and serum CTX of 17.459 ± 4.363 pg/mL (P = .000) at 8 weeks after subgingival instrumentation. There was significant decrease in eosinophil count (P = .018) and mean platelet volume (P = .016) at 8 weeks after subgingival instrumentation; however, no significant change was found in other hematologic parameters. CONCLUSION: Following subgingival instrumentation, biomarkers of both systemic inflammation (interleukin 6) and bone turnover (CTX) were observed to reduce significantly. This finding hints towards a positive impact of periodontal intervention on bone health.

Impact of Polycystic Ovary Syndrome on Periodontal Status of Women of Adolescent and Adult Age Groups: A Cross-Sectional Study.

OBJECTIVE: Polycystic ovary syndrome (PCOS) is identified as the most common endocrine disorder in reproductive-aged women, and symptoms of PCOS appear during the early pubertal age. There is a gap in knowledge in recognizing the status of gingival inflammation/periodontal destruction and high-sensitivity C-reactive protein levels (hsCRP) in adolescents versus adults with PCOS. This study aimed to observe the impact of PCOS on periodontal status and systemic inflammation in adolescents and compared them with adults with PCOS. METHODS: A total of 100 newly diagnosed female subjects with PCOS were enrolled into two groups: adolescents (11-19 years, n = 50) and adult females (20-40 years, n = 50). Periodontal parameters, anthropometric parameters, PCOS phenotype, hirsutism score, and serum hsCRP levels were recorded. RESULTS: High levels of mean hsCRP, gingival index, and bleeding on probing % were observed in adolescent and adult PCOS groups, though nonsignificant between the groups (p > 0.05). Significantly more sites with probing pocket depth 3-4 mm, higher mean clinical attachment level (CAL) and sites with CAL 1-2 mm, and high frequency of patients (n = 11) with periodontitis (stage 1) were observed in adults with PCOS compared to adolescents (p ≤ 0.05). Similar and predominant prevalence of PCOS phenotype A (66%) and moderate hirsutism (46% adolescents vs. 58% adults) were observed in both groups. CONCLUSION: Similar levels of hsCRP and periodontal inflammation were found in adolescents and adults with PCOS. More periodontal tissue destruction was observed in adults with PCOS as compared to adolescents with PCOS.

Comparative evaluation of microneedling vs injectable platelet-rich fibrin in thin periodontal phenotype: a split-mouth clinical randomized controlled trial.

OBJECTIVES: Microneedling and injectable platelet-rich fibrin (i-PRF) have been proposed as relatively less invasive alternatives to surgical procedures for augmentation of thin periodontal phenotype. The present study was conducted to evaluate the effect of microneedling and i-PRF alone on gingival thickness in thin periodontal phenotype individuals. METHOD AND MATERIALS: Systemically healthy individuals with thin periodontal phenotype in mandibular anterior teeth (n = 21) were treated with microneedling on one side and i-PRF on the contralateral side. Assessment of gingival thickness, keratinized tissue width, and periodontal parameters was done at baseline, and at 1, 3, and 6 months. RESULTS: In intergroup comparison, a statistically significant increase in gingival thickness was observed with microneedling as compared to i-PRF at 6 months (P < .02). Intragroup comparison from baseline to 6 months showed a statistically significant increase in gingival thickness within both the groups: microneedling from 0.78 ± 0.12 mm to 1.00 ± 0.14 mm (P < .000), and i-PRF from 0.77 ± 0.10 mm to 0.93 ± 0.12 mm (P < .000). Intragroup comparison showed a statistically significant increase in keratinized tissue width in the microneedling group (P < .000). A statistically significant decrease in periodontal parameters was observed on intragroup comparison (P < .000). CONCLUSION: Considering the higher gain in gingival thickness and the added advantage of eliminating need for autologous blood withdrawal, microneedling is potentially better than i-PRF for phenotype modification in thin periodontal phenotype individuals.

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.

Impact of supragingival scaling on the outcomes of subgingival instrumentation completed after 1 week: a split-mouth randomized clinical trial.

OBJECTIVE: To investigate the impact of supragingival scaling on the clinical outcomes of subgingival instrumentation completed after 1 week. METHOD AND MATERIALS: In 27 patients with Stage II and Stage III periodontitis, pairs of contralateral quadrants were randomly assigned into test group 1 (single sitting scaling and root planing) and test group 2 (supragingival scaling followed by subgingival instrumentation after 1 week). Periodontal parameters were recorded at baseline, 2, 4, and 6 months; Gingival crevicular fluid vascular endothelial growth factor (VEGF) estimation was done at baseline in both groups and 7 days after supragingival scaling in test group 2. RESULTS: At 6 months, significantly better improvement in test group 1 at sites with periodontal probing depth (PPD) > 5 mm; (∆PPD = 2.32 mm vs 1.41 mm, P = .001; ∆clinical attachmen level [CAL] = 2.34 mm vs 1.39 mm, P = .001) was observed. Supragingival scaling resulted in significant reduction in gingival crevicular fluid VEGF (42.46 to 27.88 pg/site) after 1 week. Regression analysis explained 14% variance in VEGF to baseline PPD at sites with PPD > 4 mm; and 21% variance in CAL improvement to VEGF at sites with PPD > 5 mm. The percentage of sites with PPD = 5 to 8 mm reaching the clinical endpoint was 52% and 40% for test group 1 and test group 2, respectively. Better results were noticed in bleeding on pocket probing-positive sites in both groups. CONCLUSION: The sites with PPD > 5 mm where supragingival scaling was followed by subgingival instrumentation after 1 week resulted in less favourable treatment outcomes.

Effect of antibiotics as an adjuvant to subgingival instrumentation on systemic inflammation in patients with periodontitis: a randomized clinical trial.

OBJECTIVES: The aim of the present study was to evaluate the effect on systemic inflammation of subgingival instrumentation (SI) with or without antibiotics. Moreover, systemic parameters were compared between periodontally healthy (PH) individuals and periodontitis patients. METHOD AND MATERIALS: Patients with generalized periodontitis: stage III and PH individuals were recruited. Forty eight periodontitis patients were randomly allocated to each treatment group; systemic antibiotics for seven days after completion of SI (AB group), or SI alone (SI group). Periodontal parameters, serum high-sensitivity C-reactive protein (hsCRP), and hematological parameters were assessed at baseline and at week 8. Multivariate analysis was applied to analyze predictive effect of treatment allocated and improvement in periodontal parameters on change in systemic parameters. RESULTS: At baseline, hsCRP, total leukocyte count (TLC), neutrophil, and monocyte count were significantly higher in periodontitis patients. There was comparable reduction in neutrophil count in both treatment groups. At week 8, change in periodontal parameters was similar in treatment groups, except for probing pocket depth (PPD). Improvement in both PPD and clinical attachment level (CAL) and CAL alone was predictive of change in TLC and lymphocyte count, respectively. CONCLUSION: This study failed to demonstrate the significant benefit of systemic antibiotics as an adjuvant to SI on improvement in periodontal inflammation and systemic inflammatory parameters, despite significantly higher reduction in PPDs.

Assessment of Periodontal Status in Patients with Depression: A Cross-Sectional Study.

OBJECTIVE: Depression leads to behavioral and systemic changes making individuals more susceptible to inflammatory diseases. This study was conducted to assess the periodontal status of patients with clinically diagnosed mild and moderate depression. SUBJECTS AND METHODS: This cross-sectional study included 135 participants. Test group 1 (n = 45) consisted of patients clinically diagnosed with mild depression, test group 2 (n = 45) included patients with moderate depression and the control group (n = 45) included non-depressive participants. Sociodemographic characteristics and periodontal parameters were recorded. RESULTS: Plaque levels and gingival inflammation were significantly (p < 0.05) higher in mild and moderate depression patients than in controls. Significant greater number of sites with bleeding on probing, increasing probing pocket depth (PPD), sites with PPD 4-5 mm, ≥6 mm, attachment loss 3-4 mm, and high prevalence with grade C periodontitis were observed in moderate depression patients, compared to patients with mild depression and healthy controls. On applying partial correlation, periodontal parameters were positively correlated with depression, while a negative correlation was found with income status. On regression analysis, bleeding on probing as a dependent variable was also associated with depression. CONCLUSIONS: Patients with moderate depression showed high periodontal destruction and inflammation as compared to those with mild depression. Further, deep pockets were associated with depressive patients. Periodontal care is required in such patients so that the progression of periodontal diseases can be prevented at the earliest.

Personality traits, oral health beliefs, and periodontal parameters in patients with periodontitis.

OBJECTIVES: Recognizing the construct of the Big Five personality factors with health beliefs could help in better evaluation of distinctive factors that may impact a patient's behavioral responses with reference to compliance to primary and secondary preventive measures in periodontitis. The aim of the present study was to explore association among the personality traits, oral health beliefs, and periodontal parameters in patients with periodontitis. METHOD AND MATERIALS: The present single-centered, cross-sectional study consisted of 118 systemically healthy participants with generalized periodontitis stage II and III with grade B. The neuroticism-extraversion-openness five-factor inventory 3 (NEO-FFI-3) instrument was applied to assess personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness). The oral health belief questionnaire was administered to determine five oral health beliefs, namely perceived seriousness (PS), benefit of preventative practices (BPP), benefit of plaque control (BPC), efficacy of clinicians (EC), and perceived importance (I). RESULTS: Spearman correlation analysis revealed that BPP and BPC were inversely correlated with neuroticism. Extraversion was positively correlated with the personality traits openness to experience, agreeableness, and conscientiousness, whereas it was inversely correlated with neuroticism. Binomial logistic regression showed that the predictor "very low" and "low" levels of conscientiousness were positive and significant for clinical attachment loss ≥ 4.89 mm (b = 1.90 and 1.55; standard error = 0.70 and 0.72, P = .007 and .033), with odds ratios of 6.73 (95% CI 1.68 to 26.95) and 4.75 (95% CI 1.13 to 19.83). CONCLUSION: The intensity of an individual's perception of the benefits of clinicians achieving dental health is directly correlated with levels of conscientiousness. Trends of higher odds ratios for clinical attachment loss were observed with decreasing levels of conscientiousness. (Quintessence Int 2023;54:200-208; doi: 10.3290/j.qi.b3648947).

Clinical evaluation of root coverage in Miller class III/RT2 labial gingival recession treated with interdisciplinary periodontal-orthodontic therapy: a randomized controlled clinical trial.

PURPOSE: The aim of current study was to evaluate percentage root coverage (RC%) in isolated Miller class III/RT2 labial gingival recession (GR) associated with malaligned mandibular anteriors, using interdisciplinary periodontal-orthodontic treatment as compared to mucogingival surgery alone. METHODS: Thirty-six systemically healthy patients having isolated Miller class III/RT2 GR with respect to malaligned mandibular anteriors, were randomly divided into test group: mucogingival surgery using subepithelial connective tissue graft followed by orthodontic treatment and control group: mucogingival surgery alone. Primary clinical parameters included (RC%), recession depth, keratinized tissue width, mid-labial clinical attachment level, interdental clinical attachment level (iCAL), periodontal phenotype (PP), gingival thickness (GT), root coverage esthetics score (RES) and hypersensitivity. Total duration of follow up was 12 months. RESULTS: Mean RC% was significantly more achieved in test group (66.67%±40.82%) in comparison to control group (39.93%±31.41%) at the end of study (P=0.049). Further, complete root coverage was attained in 5/8 cases of test group versus 1/2 cases of control group after 3/12 months respectively. RES and hypersensitivity, showed statistically significant improvement after complete follow up period in both the groups. An ideal RES score of 10 was achieved in 4/7 cases of test group while in 1/2 cases of control group after 3/12 months respectively. Correlation analysis revealed significant negative correlation between RC% and iCAL. Correlation of RC% with GT and PP was non-significant. CONCLUSIONS: Interdisciplinary periodontal-orthodontic approach may be more beneficial in terms of achieving improved RC%, esthetic and resolution of hypersensitivity in the management of Miller class III/RT2 GR in malaligned mandibular anteriors.

Detection of Epstein Barr Nuclear Antigen-1 (EBNA-1), Early Antigen 1F, 2R (EA-1F, EA- 2R) along with Epstein-Barr virus Latent Membrane Protein 1 (LMP1) in Breast Cancer of Northern India: An Interim Analysis.

INTRODUCTION: Worldwide, breast cancer (BC)  is a prominent cause of death, with a disproportionately high incidence in developed countries. Epstein-Barr virus (EBV) infection has been reported in up to 90% of the world's population.  Although the exact link of EBV infection and breast carcinoma is not yet determined. The present study was carried out to assess the pathological correlation of EBV infection and BC in women from Northern India. METHODOLOGY: In this prospective observational study, 130 patients with histologically proven breast carcinoma were included. After detailed histology, the paraffin block with infiltrative tumor was selected for molecular analysis and further immunohistochemistry (IHC)- EBV PCR and Epstein-Barr virus latent membrane protein 1 (LMP1) IHC. RESULTS: Most of the patients were diagnosed with Infiltrating Ductal Carcinoma not otherwise specified (IDC-NOS), followed by Infiltrating Ductal Carcinoma + Ductal Carcinoma in situ (IDC + DCIS). The total of 25 tissues of breast carcinoma had positive EBV PCR results (19.23%). The co-relation between the molecular and immunohistochemical results was significant in 11/25 cases that showed immunoexpression for LMP1 by IHC. Sensitivity of 44% and specificity of 100% were observed for LMP1 IHC, having a PPV value of 100% and an NPV of 88%. No significant correlation was observed between age, tumor subtype, grade, stage with respect to EBV infection; however, there was a significant association with nodal metastasis with extra nodal extension in tumors that had EBV infection. CONCLUSION: The present study establishes an association between LMP1 and patients with EBV positive breast cancer. The authors suggest that additional multicentric studies be conducted to strengthen the reliability and generalizability of the observations of the current study.

Impact of scaling and root planing on association of site- and tooth-specific factors with bleeding on pocket probing.

OBJECTIVES: This study was conducted to elucidate the link of site-specific, tooth-related, and patient-associated factors with bleeding on pocket probing (BOPP) and the impact of scaling and root planing over these factors. METHOD AND MATERIALS: This cross-sectional study comprised of 50 untreated periodontitis patients and 50 periodontitis patients who had received scaling and root planing in the last 6 to 12 months and were on supportive periodontal therapy. Multilevel modeling was applied to data, with BOPP being the dichotomous outcome variable. Variables that revealed a significant association with BOPP in multilevel modeling were analyzed further to find the influence of the treatment group (untreated periodontitis and treated periodontitis) on the association between predictor variables and BOPP. RESULTS: Odds ratio (OR) for BOPP in untreated periodontitis versus treated periodontitis was 1.493, and in molars versus anterior teeth this was 1.439. Untreated periodontitis had an OR of 3.500 compared to treated periodontitis, in anterior teeth with Plaque Index 0. This was 2.795 and 7.734 in treated periodontitis and 5.106 and 12.762 in untreated periodontitis at Plaque Index 1 and 2, respectively. Bleeding on marginal probing had an OR of 6.984 for BOPP. Bleeding on marginal probing negative sites had higher OR in untreated periodontitis irrespective of the probing pocket depth. CONCLUSION: Plaque control is more effective in controlling periodontal inflammation after scaling and root planing. The probability of BOPP in the absence of bleeding on marginal probing is higher in untreated patients. The scope of influence of marginal inflammation on periodontal inflammation in shallow pockets is more in untreated periodontitis as compared to treated periodontitis; however, the trend reverses in deep pockets.

Management of Isolated Labial Mucosal Fenestration by Endodontic Microsurgery Along With Platelet-Rich Fibrin and Connective Tissue Graft: A Series of Four Cases.

INTRODUCTION: The purpose of this case report is to present endodontic and periodontal management of mucosal fenestrations with exposed root apices. The treatment protocol in present cases includes a combination of regenerative therapy using platelet-rich fibrin (PRF) with connective tissue graft (CTG) and endodontic microsurgery. Pre-existing condition of these teeth exhibits apical lesion with prominent root position and complete buccal bone dehiscence/fenestration presents a true challenge to successful outcome. CASE PRESENTATION: Four patients having concomitant mucosal fenestrations with an apical lesion and complete denudation/fenestration of the buccal plate were treated with root canal treatment and then by endodontic microsurgery. After the root-end resection and retrograde filling, PRF was placed in the bone defect maintaining intimate contact with the bone surface. CTG was harvested from the palate, placed over the PRF, and beneath the flap corresponding to the mucosal fenestration defect, and sutured with the flap to ensure a secured position. The flap was then repositioned and sutured. All patients showed the complete coverage of the mucosal fenestration with no post-operative complications and were followed up to 2-5 years. CONCLUSION: Peri-radicular endodontic microsurgery and CTG along with PRF may be used as a predictable treatment option to manage the mucosal fenestrations in such challenging cases.

Assessment of the effect of orthodontic treatment on the stability of pre-orthodontic recession coverage by connective tissue graft: a randomized controlled clinical trial.

OBJECTIVE: To compare the changes in periodontal parameters after orthodontic treatment in patients having isolated gingival recession treated with and without pre-orthodontic gingival recession coverage. METHOD AND MATERIALS: Thirty-six patients requiring orthodontic treatment with a facially positioned mandibular anterior tooth with labial recession were randomly allocated to either test group: root coverage by subepithelial connective tissue graft (SCTG) followed by orthodontic treatment, or control group (orthodontic treatment only). Primary clinical parameters included recession depth, keratinized tissue width, root coverage, root esthetic score, and gingival phenotype. The patients were followed up for at least 1 year. RESULTS: Level of gingival margin attained in test group teeth after SCTG were maintained at end of orthodontic treatment (P = .727). Root coverage achieved was 69.33 ± 30.74% versus 22.36 ± 27.70% in test and control group, respectively (P = .000), and gain in keratinized tissue width was 1.59 ± 0.73 mm in test versus 0.41 ± 0.49 mm in control group (P = .000). The number of teeth with improved gingival phenotype and decreased hypersensitivity was also observed to be statistically significant in the test group (P = .049, P = .002). CONCLUSION: Root coverage procedure may be performed before the planned orthodontic treatment as graft stability is preserved throughout the course of orthodontic treatment.

Effect of orthodontic treatment on periodontal health of periodontally compromised patients.

OBJECTIVES: To evaluate the effect of fixed orthodontic treatment on periodontal parameters in periodontally compromised adult orthodontic patients. MATERIALS AND METHODS: This was a prospective, randomized, controlled clinical trial. Thirty-six periodontally compromised adult patients (mean age: 29.67 ± 4.8 years) were randomly allocated to either test (perio-ortho) or control group (perio). After periodontal stabilization in both groups, orthodontic treatment was started in the test group, whereas the control group remained on periodontal maintenance only. Evaluation and comparison of clinical parameters (plaque index [PI]; gingival index [GI]; bleeding on probing [BOP]; probing depth [PD]; clinical attachment level [CAL]) of both groups was assessed at three time intervals: T0 (base line), T1 (at start of orthodontic treatment), and T2 (1 year after start of orthodontic treatment). Radiological parameters (alveolar bone levels [ABL]) were recorded using CBCT at T1 and T2. RESULTS: Intragroup analysis showed statistically significant improvement in all clinical and radiological periodontal parameters in both groups (P ≤ .05). Intergroup comparison revealed improvement in the periodontal parameters was not statistically significant between the groups (P ≥ .05). Subgroup analysis showed reduction in the number of moderate and severe periodontitis sites in both groups with significant more gains in ABL in the test group compared to the control group. CONCLUSIONS: Orthodontic treatment after periodontal stabilization does not have any detrimental effect on periodontal health in adult periodontally compromised orthodontic patients and may add to the benefits achieved by periodontal treatment alone.

Titanium Allergy in Dentistry: A New Allergen in Rapidly Evolving Implant Dentistry.

Although titanium is considered as the biocompatible material and widely used in medical and dental fields, the clinical application of this material is still a critical issue due to the possible adverse host response. Very few case reports related with titanium-based hypersensitivity reactions with dental implants proved the existence of titanium allergy. The present case report describes 56-year-old male showing allergic symptoms after 1 week of dental implant placement with no perioral or facial signs, but eczema was shown on the distant body parts, and the complete remission was attained after removing the dental implant.

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.

Clinical evaluation of impact of periodontal phenotype on the outcome of open flap debridement in patients with chronic periodontitis: A comparative interventional study.

BACKGROUND: Several studies have implicated the role of periodontal phenotype (PP) in the outcome of various periodontal interventions. However investigations have not been performed to estimate such impact on the outcome of open flap debridement (OFD) for the management of chronic periodontitis. METHODS: A total of 73 individuals with chronic periodontitis underwent scaling and root planing (SRP). Eight weeks following SRP, modified Widman flap (MWF) surgery was performed in 40 patients (20 of either PP) presenting with probing depth (PD) ≥4 mm and gingival index (GI) ≥1 at ≥4 sites distributed over ≥2 anterior teeth with radiographic evidence of horizontal bone loss. PD, clinical attachment level (CAL), gingival recession, plaque index, GI, and bleeding on probing (BOP) were recorded at baseline, 3 and 6 months. PP was assessed using transparency of periodontal probe through the gingival margin at midfacial level. RESULTS: A total of 34 patients were re-evaluated after intervention. All periodontal parameters improved in both groups after periodontal surgery. PD & PP were found to have positive correlation with CAL gain in ≥7 mm probing sites. Attachment gain of >2 mm was observed in more percentage of sites in thick PP than in thin PP. CONCLUSION: PP can be an important factor influencing CAL gain in OFD.

Comparative clinical and radiographic evaluation of demineralized freeze-dried bone allograft with and without decortication in the treatment of periodontal intrabony defects: a randomized controlled clinical study.

OBJECTIVES: Regeneration of intrabony defects is a challenging target of periodontal therapy. The biologic rationale for regeneration not only is based on incorporating the regenerative material, but also takes into consideration the defect's inherent healing capacity. The present study was carried out to evaluate the efficacy of decortication or intramarrow penetration performed with demineralized freeze-dried bone allograft (DFDBA) in the management of intrabony defects. METHOD AND MATERIALS: Forty chronic periodontitis (stage II and III periodontitis) patients having 40 intrabony defects were randomly assigned into test group (intrabony defect filled with DFDBA after intramarrow penetration along with open flap debridement [OFD+IMP+ DFDBA]) and control group (DFDBA along with open flap debridement [OFD+DFDBA]). Primary outcome measures included probing pocket depth, clinical attachment level, and percentage bone fill (%BF). All parameters were recorded at baseline, 6 months, and 9 months postsurgical follow-up. RESULTS: Mean reduction in probing depth and gain in clinical attachment level was statistically significantly higher at the interdental defect site in the test group compared to the control group at 9 months follow-up (P = .02 and .04, respectively). In radiographic parameters, statistically significant improvements in defect depth and gain in defect area were found in the test group (P = .00 and .03, respectively). Statistically significant improvements in %BF and linear bone growth (P = .02 and .00, respectively) were also observed in the experimental group (39.47 ± 13.92% and 1.41 ± 0.54 mm) in comparison with the control group (19.29 ± 14.24%, 0.62 ± 0.49 mm). CONCLUSION: Addition of intramarrow penetration with DFDBA in surgical periodontal therapy may enhance the healing potential of periodontal intrabony defects, as observed by greater improvement in clinical and radiographic outcomes.

A case of Philadelphia chromosome-positive acute myeloid leukaemia with missense mutation R132c (c.394 c>t) and single nucleotide polymorphism rs11554137(G105G) in isocitrate dehydrogenase 1 gene.

Acute myeloid leukaemia (AML) is a heterogeneous disease due to its variable clinical, morphological and genetic features. New chromosomal and molecular abnormalities are being studied to evaluate novel treatment options and prognostic implications. We report a patient with AML who was Philadelphia chromosome-positive along with IDH1R132 mutation and SNP rs11554137(IDH1105GGT). Due to limited reports regarding these aberrations in patients with AML, there is no consensus regarding their prognostic implications. To the best of our knowledge, the presence of Philadelphia chromosome, IDH1R132 and SNP rs11554137 in a single AML patient with good prognosis is a novel finding.
