Comparative Evaluation of Pain Scores during Periodontal Probing with or without Anesthetic Gels

Context. The initial periodontal examination which includes full-mouth periodontal probing is one of the discomforting procedures for a patient. Aim. To evaluate the efficacy of two local anesthetic gels in the reduction of pain during periodontal probing using Florida probe in CGP patients in comparison with manual probing. Materials and Methods. Ninety systemically healthy patients with moderate to severe CGP patients were recruited. In each patient, the quadrants were randomly assigned to manual probing with UNC-15 probe, probing with Florida probe, and Florida probing with lidocaine 10% gel and with benzocaine 20% gel. In the quadrants undergoing probing with anesthetic gels, the sites were isolated and the gel was injected using syringe and a blunt-end cannula. Pain was measured using 10 mm horizontal VAS. Statistical Analysis. The analysis was carried out using SPSS version 18. The comparison of mean VAS scores was done using repeated measures ANOVA with post hoc Bonferroni test. Results. Mean VAS for manual probing was significantly more than Florida probing. Further, the mean VAS score for Florida probing was higher than the two gels. Conclusion. It is suggested that the gels might be useful in reducing pain experienced during full-mouth periodontal probing in patients with CGP

Maxillary Incisive Canal Characteristics: A Radiographic Study Using Cone Beam Computerized Tomography

Background. The incisive canal located at the midline, posterior to the central incisor, is an important anatomic structure of this area to be considered while planning for immediate implant placement in maxillary central incisor region. The purpose of the present study is to assess incisive canal characteristics using CBCT sections. Materials and Methods. CBCT scans of 79 systemically healthy patients, with intact maxillary incisors, were evaluated by two calibrated and independent examiners. Assessments included (1) mesiodistal diameter, (2) labiopalatal diameter, (3) length of the incisive canal, (4) shape of incisive canal, and (5) width of the bone anterior to the incisive foramen. Results. The mean width of the foramen labiopalatally and mesiodistally was 3.12 ± 0.94 mm and 3.23 ± 0.98 mm, respectively. Mean canal length was 18.63 ± 2.35 mm and males have significantly longer incisive canal than females. The mean width of bone anterior to the incisive canal was 6.32 ± 1.43 mm. As age of the subjects increased, incisive foramen diameter and incisive canal length were found to be increased. Cylindrical shaped incisive canals were seen in most of the individuals followed by funnel shaped and hour-glass shaped canals, and banana-like canal is least prevalent type. Conclusion. The findings from the present study suggest that the diameter and length of incisive canal vary among different individuals and presence of very thin bone anterior to the canal would suggest that a pretreatment CBCT scan is a valuable tool to evaluate anatomic variations, morphology, and dimensions of incisive foramen before immediate implant placement in maxillary central incisor region

Comparative evaluation of hemodynamic, vasoconstrictive, and SpO2variability during different stages of periodontal surgery performed using 0.5% ropivacaine or 2% lignocaine HCl (1:80,000 adrenaline) local anesthesia: A randomized, double-blind, split-mouth pilot study

Aim: The aim of this study is to compare anesthetic, hemodynamic, vasoconstrictive, and SpO2variability of 0.5% ropivacaine to the “gold standard” lignocaine (2%) with epinephrine (1:80,000) during periodontal surgery. Materials and Methods: A total of 20 systemically healthy controls meeting the inclusion criteria were selected from the Outpatient Department of Sri Sai College of Dental Surgery. Preoperatively, all participants were infiltrated with 0.5 ml of 0.5% ropivacaine intradermally as test solution to record any allergic reaction. Open flap debridement was performed using local anesthesia containing 2% lignocaine hydrochloride with 1:80,000 epinephrine or 0.5% ropivacaine. Recordings were made of the time of onset, duration of action, the intensity, and depth of anesthesia and various hemodynamic changes throughout the surgical procedure. In addition, blood loss volume and postoperative pain were also assessed. Results: Ropivacaine showed statistically longer duration of action (mean±SD =5.3±0.71 hrs) than lignocaine with epinephrine (mean=2.14±0.98 hrs). Blood loss during flap surgery was comparatively less when performed under ropivacaine. No statistical differences were observed in systolic BP, diastolic BP, SpO2 and heart rate during different stages of periodontal surgery between either of the local anesthetic agents Conclusion: Ropivacaine demonstrates comparable efficacy as lignocaine with added advantage of longer duration of action and superior postoperative pain control. No adverse events from this newer anesthetic were noted, and hence, it can be used safely as a viable local anesthetic for periodontal surgical procedures

Prevalence of aggressive periodontitis in rural population around Vikarabad ( India) - An epidemiological study

Introduction: The prevalence of aggressive periodontitis (AP) has been extensively studied globally. Limited information is available on the AP prevalence in the Indian population. Hence a survey of the susceptible students of educational institutions in villages around Vikarabad, Andhra Pradesh, India, was undertaken to give a more accurate prevalence of aggressive periodontitis in the population and relevant preventive and remedial measures could be taken. Materials & Method: A total o f9600 subjects were screened to estimate the prevalence of AP. Subjects with loss of attachment > 4mm were recalled to Department of Periodontics, Sri Sai College of Dental Surgery, Vikarabad for clinical and radiological confirmation. Results: From 9,600 students screened, 15 cases (LAP- 9, GAP-6) were found to be confirming to the diagnosis of AP, giving aprevalence of 0.16%. Conclusions: The prevalence rate of AP in the screened population is 0.16% and is similar to other prevalence studies in Andhra Pradesh and in consonance with several other global studies. The prevalence of aggressive periodontits is highly variable and controversial globally and needs concerted and systemic approach if this is to be settled

Efficacy of local use of probiotics as an adjunct to scaling and root planing in chronic periodontitis and halitosis: A randomized controlled trial

Objective: Periodontitis is known to have multifactorial etiology, involving interplay between environmental, host and microbial factors. The current treatment approaches are aimed at reducing the pathogenic microorganisms. Administration of beneficial bacteria (probiotics) has emerged as a promising concept in the prevention and treatment of periodontitis. Thus, the aim of the present study is to evaluate the efficacy of the local use of probiotics as an adjunct to scaling and root planing (SRP) in the treatment of patients with chronic periodontitis and halitosis. Methods: This is a randomized, placebo-controlled, double-blinded trial involving 32 systemically healthy chronic periodontitis patients. After SRP, the subjects were randomly assigned into the test and control groups. Test group (SRP + probiotics) received subgingival delivery of probiotics and probiotic mouthwash, and control group (SRP + placebo) received subgingival delivery of placebo and placebo mouthwash for 15 days. Plaque index (PI), modified gingival index (MGI), and bleeding index (BI) were assessed at baseline, 1 and 3 months thereafter, whereas probing depth (PD) and clinical attachment level were assessed at baseline and after 3 months. Microbial assessment using N-benzoyl-DL-arginine-naphthylamide (BANA) and halitosis assessment using organoleptic scores (ORG) was done at baseline, 1 and 3 months. Findings: All the clinical and microbiological parameters were significantly reduced in both groups at the end of the study. Inter-group comparison of PD reduction (PDR) and clinical attachment gain (CAG) revealed no statistical significance except for PDR in moderate pockets for the test group. Test group has shown statistically significant improvement in PI, MGI, and BI at 3 months compared to control group. Inter-group comparison revealed a significant reduction in BANA in test group at 1 month. ORG were significantly reduced in test group when compared to control group. Conclusion: Within the limitations of the study, the present investigation showed that the adjunctive use of probiotics offers clinical benefit in terms of pocket depth reduction in moderate pockets and reduced oral malodor parameters

Correlation of Blood and Salivary pH Levels in Healthy, Gingivitis, and Periodontitis Patients before and after Non-Surgical Periodontal Therapy

Periodontitis is an infectious illness which leads to the inflammation of protective tissues around the teeth and the continuous loss of alveolar bone and conjunctive tissue. Biomarker analysis in serum and saliva helps in the evaluation of disease progression and activity. It is also established that every inflammatory change along with resultant damage of tissues ends up in altered pH values in the fluids and tissues. Aim: To correlate the connection of pH levels in both blood as well as saliva in healthy, periodontitis, and gingivitis patients. Materials and Methods: The current research involved 145 subjects amidst the age of 20 and 55 years. The subjects were split into three different groups: healthy (Group A), gingivitis (Group B), and finally chronic periodontitis (Group C). The recording of clinical parameters was done by gingival index (GI), probing depth (PD), and plaque index (PI). pH of saliva and blood was analyzed with the help of digital single electrode pH meter. Subjects have gone through scaling and root planning (SRP) coupled with the instructions of oral hygiene. They were recalled post 4 weeks, and saliva and blood samples were gathered for analyzing pH. Results: Clinical parameters GI and PI were statistically important in both group C as well as group B post SRP. A crucial change has been observed in attachment levels (AL) and PD in the case of periodontitis group post SRP. The difference in the salivary pH values were significant between group B vs. C and A vs. C before the treatment because the values for group C were acidic, whereas in groups B and A the pH was alkaline. After the treatment, the values were still significant because the pH has become more alkaline compared to preoperative value in both group B and C. Saliva’s pH levels have demonstrated a statistically significant reduction in group C post SRP. Conclusion: Salivary pH levels and blood evidently became alkaline in the group C patients post SRP and there is a positive correlation between them and the clinical parameters
