Association between diabetes mellitus and periodontal status in north Indian adults

Objective: The aim of the present study was to investigate the prevalence of periodontal diseases among individuals with type I and type II diabetes in north India and evaluate the association of this condition with behavioral and clinical variables. Materials and Methods: A cross-sectional study was carried out on a calculated sample of 300 individuals with diabetes. Periodontitis was defined as clinical attachment loss (CAL) >3 mm in two or more non-adjacent teeth or those that exhibited CAL >5 mm in 30.0% of teeth. All subjects were over 30 years of age and underwent a periodontal examination. Behavioral characteristics as well as medical history and dental history were obtained with a structured interview. Discrete (categorical) groups were compared by Chi-square (χ 2 ) test. A two-tailed (α=2) P Results: A total of 6.7% exhibited a healthy periodontium; 68.0% exhibited gingivitis; and 25.3% exhibited periodontitis. The univariate analysis revealed that periodontitis was statistically more prevalent among men ( P =0.001); among participants with type II diabetes ( P =0.009); those with more than five years of diabetes ( P =0.065); those with tobacco smoking habits ( P P Conclusion: Multiple determinants are associated with the prevalence of periodontitis among patients with diabetes.

An Invitro Evaluation of Antimicrobial Efficacy and Flow Characteristics for AH Plus, MTA Fillapex, CRCS and Gutta Flow 2 Root Canal Sealer.

INTRODUCTION Cleaning and shaping of root canal does not guarantee complete disinfection of the canal, regardless of the systems and techniques used for this purpose. Therefore, it becomes mandatory for the endodontic filling materials to have a good antimicrobial potential especially against E. faecalis. This research was aimed therefore to evaluate the antibacterial efficacy and flow properties of different root canal sealers. AIM To study invitro antimicrobial activity and flow characteristics for Resin based (AH Plus), Mineral Trioxide Aggregate based (MTA Fillapex), Calcium hydroxide based (CRCS) and Flowable Gutta-Percha (Gutta Flow 2) endodontic sealers on Enterococcus faecalis. MATERIALS AND METHODS Enterococcus faecalis ATCC 29212 was used to test antibacterial potential of sealers by Agar diffusion test (ADT) and Direct Contact Test (DCT). ADT was performed by punching the sealers on a well of 4×6mm diameter on Muller Hinton agar plates. These plates were inoculated with standard suspension of E. faecalis and the zone of inhibition was measured at 24 hours and after 7 days. All the sealers were prepared in accordance with the manufacturers recommendations. Flow of sealers was measured according to ADA specification no. 57. RESULTS All sealers showed antibacterial activity against E. faecalis except Gutta Flow 2. At 24 hours, zone of inhibition was highest in Calcibiotic Root Canal Sealer (CRCS) and lowest in AH Plus. After 7 days the zone of inhibition decreased in AH plus, CRCS and MTA Fillapex. DCT showed a significant lower number of organisms in AH Plus, CRCS and MTA than controls at both the time intervals. Gutta Flow 2 did not show any significant antimicrobial action. Maximum and minimum flow was shown by AH Plus and CRCS respectively. CONCLUSION Highest microbial inhibition was shown by (CRCS), followed by MTA Fillapex and AH Plus. Gutta Flow 2 did not show any inhibition of E. faecalis by ADT. Maximum reduction in antibacterial property with time against E. faecalis was seen with AH Plus. Maximum flow was shown by AH Plus and minimum by CRCS.

Dentascan an excellent tool for assessment of variations in the management of periodontal defects

Background: The purpose of the present study was to envisage the effectiveness of demineralized freeze-dried bone allograft (DFDBA) and bovine bone graft (BBG) for promoting defect fill in periodontal intrabony defects using dentascan. Materials and Methods: A total of 13 subjects (15 intrabony defects) aged between 24 and 56 years affected by moderate to severe periodontitis were randomly divided into Control (CG) and Test groups (TG1 and TG2). In CG only debridement, TG1 debridement plus DFDBA, and TG2 debridement plus BBG were performed. The clinical parameters probing pocket depth (PPD), clinical attachment level (CAL) was used. The radiological analysis was done by dentascan, which is a single-slice spiral computed tomographic scanner. Six months after, regenerative treatment clinical measurements were recorded. The bone fill was assessed using Dentascan as previously mentioned. Results: PPD reduction and CAL gain were significant in all the groups after 6 months whereas, on intergroup comparisons, insignificant finding was observed both at baseline and after 6 months. Coronoapical bone status decreased significantly in all groups, buccolingual measurements decreased significantly in TG1 and TG2, but no such trend was seen in CG. Significant reduction in mesiodistal bone status was noticed only in TG1 whereas insignificant on intergroup comparisons. Conclusion: Dentascan-based analysis attested that DFDBA was superior to BBG.

Periodontal parameters around implants and natural teeth

Introduction: Nowadays, dental implants permit consideration of as one of the most reliable therapeutic modalities during the establishment of any prosthetic treatment plan. In numerous clinical situations, implants can clearly contribute to a notable simplification of therapy, frequently enabling removable prostheses to be avoided, keeping it less invasive with respect to remaining tooth structure. The aim of the present study was to clinically assess the peri-implant and periodontal conditions after the placement of crowns in partially edentulous patients. Materials and Methods: Twenty-five participants with 28 implant supported crowns were recruited in the study. After the insertion of suprastructure, meticulous scaling and root planing were performed on adjacent teeth which served as control. The clinical examination was carried out by a single examiner after placement of crowns at an interval of 1, 3, 6, 9, and 12 months and included the assessment of modified plaque index (mPlI), bleeding score, calculus score, probing pocket depth (PPD), and recession on the four aspects of each implant and adjacent teeth. Results: The mPlI, modified bleeding index (mBlI), calculus score, PPD, and recession decreased from 1 month to 12 months in both implants and in control teeth. The mean mPlI, mBlI, and calculus score were comparatively high in control teeth than implants. PPD was found to be more on implants than in control teeth. Recession was slightly higher in control teeth than implants throughout the study period, but it was not statistically significant. Conclusion: An implant patient must always be enrolled in a supportive therapy program that involves recall visits at regular intervals.

Nasal Sinus Tract of Odontogenic Origin: Report of a Case

Extraoral sinus tract often poses a diagnostic challenge to the clinician owing to its rare occurrence and absence of symptoms. The accurate diagnosis and comprehensive management are inevitable as the aetiology of such lesions is often masked and requires holistic approach. The present case report encompasses the management of an extraoral discharging sinus tract at the base of the right nostril in a chronic smoker. The lesion which was earlier diagnosed to be of nonodontogenic origin persisted even after erratic treatment modalities. Our investigations showed the aetiology of sinus tract to be odontogenic. Initially, a five-step program as recommended by the Agency for Health Care Research and Quality was used for smoking cessation followed by root canal therapy (RCT) and surgical management of the sinus tract. The patient has been under stringent follow-up and no reoccurrence has been noted.

Coverage of denuded labial bone resulting from post space preparation with a free gingival autograft: lessons learnt.

Rehabilitation of endodontically treated teeth by post and core preparation is a common procedure in day to day dental practice. However, in some instances, post space preparation can produce excessive frictional heat leading to significant damage to the attachment apparatus of the tooth as well as to the overlying soft tissue. This report describes a case of mucosal dehiscence arising due to trauma induced by inadvertent post space preparation. The denuded mucosa was restored to its physiological position with the help of free gingival autograft obtained from the palatal donor site. The aesthetic results obtained were excellent and have been stable for a period of 2 years.
