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.

Assessment of periodontal status in patients with oral lichen planus.

OBJECTIVE: Inflammatory pathogenesis is common to periodontitis and oral lichen planus. This study was conducted to assess and compare the periodontal status of patients with and without oral lichen planus. METHOD AND MATERIALS: 108 patients comprising 54 with oral lichen planus and 54 age-matched systemically healthy participants without oral lichen planus were selected. Periodontal parameters, ie Plaque Index, Gingival Index, bleeding on probing, probing pocket depth, clinical attachment level, and periodontal phenotype were measured. RESULTS: On comparing the test and control groups, statistically significant differences were observed in respect to Plaque Index (P = .00), Gingival Index (P = .00), and bleeding on probing (P = .00). A higher proportion of sites with deeper pockets was observed in the test group (P = .00). On comparison of various oral lichen planus subtypes, significant difference was observed in respect to Gingival Index (P = .00) and bleeding on probing (P = .00). A higher proportion of sites with deeper pockets (P = .01) and greater CAL (P = .00) was observed in the erosive/atrophic subgroup compared to the reticular group. However, the differences between the reticular (a less severe form of oral lichen planus) and control group in terms of Gingival Index (P = .94), Plaque Index (P = .05), bleeding on probing (P = .17), probing pocket depth (P = .56), and clinical attachment level (P = .23) were not statistically significant. Statistically significant differences were observed in terms of Gingival Index (P = .01) and bleeding on probing (P = .00) between thin and thick periodontal phenotypes in the oral lichen planus group. Statistically significant positive correlations in periodontal parameters with increased gingival involvement and severity were observed using Spearman rank correlation coefficient. CONCLUSION: Significantly greater periodontal inflammation in the test group means there is a risk of greater attachment loss in future. Thus, increased attention towards periodontal health in these patients might reduce the rate of disease progression.

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.

Impact of periodontal phenotype on the outcome of subgingival instrumentation in Stage II and III, Grade A and B periodontitis.

Background: The influence of periodontal phenotype (PP) has been documented in the outcomes of various surgical periodontal interventions such as crown lengthening, mucogingival surgery, implant restoration, and open flap debridement. Previous studies with smaller sample sizes have assessed the role of PP on the outcome of nonsurgical periodontal therapy with inconsistent results. Aim: The aim of the current interventional study is to estimate the influence of PP on the outcome of subgingival instrumentation in Stage II and III, Grade A and B periodontitis. Materials and Methods: Fifty-two patients (n = 27 thick PP and n = 25 thin PP) underwent subgingival instrumentation using ultrasonic scalers and curettes under local anesthesia in a single sitting, and periodontal parameters were recorded at baseline, 2, 4, and 6 months. The McNemar and Chi-square tests were applied for categorical data, whereas the Wilcoxon signed-rank test and Mann-Whitney U-test were applied for continuous data in intra- and intergroup comparisons, respectively. Results: Significantly better improvements in deeper pockets (>5 mm) with thick PP were observed. Loss of attachment was found in thin, bleeding on probing (BOP)-negative sites with an initial probing depth of ≤3 mm. However, BOP-positive sites belonging to both groups exhibited higher improvements in terms of clinical parameters. Conclusion: Probing depth, PP, and periodontal inflammation recorded in terms of BOP influence the gain in clinical attachment following subgingival instrumentation.

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.

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.

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.

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.

A rare case report of pleomorphic adenoma of the upper lip: An unusual clinical presentation.

Pleomorphic adenoma is the most common salivary gland tumor which accounts for about 60% of all salivary neoplasms. It is also known as "mixed tumor because of its wide cytomorphologic diversity". Pleomorphic adenoma salivary glands mostly occurs on the palate, but the involvement of the upper lip is rare. The present report describes a case of a 62-year-old male with asymptomatic firm nodular swelling attached with upper lip which was later diagnosed as pleomorphic adenoma in the excisional biopsy.

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.

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.

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.

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.

Trigeminal neuralgia secondary to cerebellopontine angle tumor: A case report and brief overview.

Trigeminal neuralgia (TN) is a paroxysmal shock-like pain restricted to innervations of the areas of one or more branches of the trigeminal nerve, often set off by light stimuli in a trigger zone. Pain attacks occur spontaneously and can also be triggered by a nonpainful sensory stimulus to the skin, intraoral mucosa surrounding the teeth, or tongue. The pathogenesis of TN is uncertain and typically is idiopathic, but it may be due to a structural lesion. Some pathologies include traumatic compression of the trigeminal nerve by neoplastic or vascular anomalies and intracranial tumors or demyelinating conditions such as multiple sclerosis. This case report describes an epidermoid cyst at the cerebellopontine angle in a 25-year-old young man with otherwise classical unilateral TN. The case highlights the difficulties of diagnosis and the importance of a multidisciplinary approach in making the correct diagnosis in symptomatic as well as classical TN.

Platelet-rich fibrin along with a modified minimally invasive surgical technique for the treatment of intrabony defects: a randomized clinical trial.

PURPOSE: The modified minimally invasive surgical technique (M-MIST) has been successfully employed to achieve periodontal regeneration. Platelet-rich fibrin (PRF) is known to enhance wound healing through the release of growth factors. This study aimed to observe the outcomes of periodontal surgery when M-MIST was used with or without PRF for the treatment of isolated intrabony defects. METHODS: This randomized clinical trial was conducted on 36 systemically healthy patients, who had chronic periodontitis associated with a single-site buccal probing pocket depth (PPD) and clinical attachment level of ≥5 mm. Patients were randomly divided into 2 groups: the test group treated with M-MIST and PRF, and the control group treated with M-MIST alone. The primary periodontal parameters analyzed were PPD, relative attachment level (RAL), and relative gingival margin level. The radiographic parameters analyzed were change in alveolar crest position (C-ACP), linear bone growth (LBG), and percentage bone fill (%BF). Patients were followed up to 6 months post-surgery. RESULTS: Intragroup comparisons at 3 and 6 months showed consistently significant improvements in PPD and RAL in both the groups. In intergroup comparisons, the improvement in PPD reduction, gain in RAL, and the level of the gingival margin was similar in both groups at 3 and 6 months of follow-up. Furthermore, an intergroup comparison of radiographic parameters also demonstrated similar improvements in C-ACP, LBG, and %BF at 6 months of follow-up. CONCLUSIONS: M-MIST with or without PRF yielded comparable periodontal tissue healing in terms of improvements in periodontal and radiographic parameters. Further investigation is required to confirm the beneficial effects of PRF with M-MIST. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03169920.

Papillary Height and its Relation with Interproximal Distances and Cementoenamel Junction in Subjects with Chronic Periodontitis. A Cross-Sectional Study.

INTRODUCTION: Presence of intact interdental papilla is considered as an essential component of aesthetic dentistry. Loss or absence of interdental papilla creates black triangles which are unpleasing. AIM: The purpose of the present study was to determine relation of interproximal distances and cementoenamel junction with the classification of interdental papilla recession after surgical exposure in chronic periodontitis patients. MATERIALS AND METHODS: This cross-sectional, single masked study group involved 198 interdental papillae in 50 chronic periodontitis patients subjected to open flap debridement. The subjects were divided into three groups according to loss of height of interdental papillae: Class I papilla, Class II papilla, Class III papilla. The interproximal distances included vertical and horizontal distance. The vertical distance was measured from apical point of the contact area to alveolar crest; horizontal distance was measured between roots at the alveolar crest. Distance from mid buccal cementoenamel junction to apical point of the contact area was also measured. RESULTS: The vertical distance was found to be significantly affecting all the classes of loss of papillary height (p<0.05). Significantly positive correlation was found between vertical distance and buccal cementoenamel junction (p<0.05). On applying multiple linear regressions vertical distance was found to be strongest determinant of loss of papillary height. CONCLUSION: Although interproximal distances and cementoenamel junction affect the height of interdental papilla, other factors influencing the existence of interdental papilla should also be taken into consideration for treatment planning to achieve better aesthetics.
