Lesions of endodontic origin: An emerging risk factor for coronary heart diseases.

A high inflammatory state, such as atherosclerosis, is a major underlying cause of coronary heart diseases (CHDs). Inflammatory mediators are known to lead to endothelial dysfunction and play a key role in initiation, progression, and rupture of atherothrombotic plaque. Chronic inflammatory dental infections such as periodontitis and lesions of endodontic origin or chronic apical periodontitis (CAP) may provide an environment conducive for such events. Atherosclerosis has shown to share a common spectrum of inflammatory markers with apical periodontitis. The possible correlation between CHD and CAP is emerging at microbiological, clinical, inflammatory, and molecular levels. This less recognized fact should be discussed more among the dental and medical fraternity so that more awareness and positive approach toward oral health can be created among patients and health-care providers.

Analysis of socket preservation using polylactide and polyglycolide (PLA-PGA) sponge: a clinical, radiographic, and histologic study.

The aim of this study was to evaluate the extraction socket healing and dimensional changes following alveolar ridge preservation using polylactide and polyglycolide (PLA-PGA) sponge. Fifteen patients were selected for alveolar socket preservation immediately following tooth extraction. Monoradicular maxillary and mandibular teeth were evaluated. The selected sockets had intact sockets walls with a minimum of 7 mm of residual alveolar bone height. The test sites were thoroughly debrided and grafted with PLA-PGA sponge, while the control sites underwent natural healing. Computed tomography (CT) measurements were taken at baseline and 6 months. After 6 months of healing, final CT measurements were performed, and trephine core biopsy specimens were obtained for histologic analysis. Implants were placed immediately after biopsy harvesting. All subjects completed the study, and all sites healed without adverse events and allowed for implant placement. The mean difference in socket height, width, and density after 6 months was statistically significantly higher in the test sites compared with control sites. Clinical measurement at the midbuccal site of the alveolar socket showed a mean loss of 2.45 ± 0.67 mm in the control group, compared with a mean gain of 1.28 ± 0.58 mm in the test group. All test sites showed minimal ridge alterations, and statistically significant differences were observed between the test and control sites with respect to bone composition and horizontal and vertical bone loss, indicating that PLA-PGA sponge is suitable for alveolar ridge preservation.

Comparative analysis of hyaluronan gel and xanthan-based chlorhexidine gel, as adjunct to scaling and root planing with scaling and root planing alone in the treatment of chronic periodontitis: A preliminary study.

AIM: The aim of this study was to evaluate the effects of hyaluronan (HA) and chlorhexidine (CHX) gels as adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis. MATERIALS AND METHODS: Sixty patients within the age group of 30-65 years recruited to participate in the study were randomly equally divided into three groups. Complete SRP and subgingival debridement were performed within 6 h in all the patients. For control (Group I) patients, SRP was the only treatment modality given; for Group II and III patients, at least 8 teeth with 4-8 mm probing pocket depth (PPD) were selected for subgingival application of HA gel and CHX gel, respectively. Clinical periodontal parameters such as gingival index, PPD, and clinical attachment level (CAL) were recorded at baseline and 3 months, whereas plaque index was recorded at baseline, 1 month, and 3 months. For measuring systemic/hematological parameters, blood samples for laboratory tests for total leucocyte count (TLC), differential leucocyte count (DLC), and C-reactive protein (CRP) were obtained using standard 2-mL syringe from each subject in all the three groups at baseline, 24 h, and on the 1 month and 3 months post-baseline. RESULTS: In all the three groups, a significant reduction in PPD and gain in CAL were observed between baseline and 3 months follow-up (P< 0.05); however, at 3 months, change in PPD and CAL was more in Group II than Group III, but the difference was non-significant, and Group I (control) showed less changes in PPD and CAL than both experimental groups. Only one patient revealed positive value for CRP at baseline only, and hence could not be statistically analyzed. In all the three groups, the peak values for TLC count were observed at 24 h. At 1-month and 3-month intervals, a significant improvement in TLC and DLC counts was observed among the experimental (HA gel/SRP and Xan-CHX gel) groups as compared to control group (SRP alone).

Management of pulpal floor perforation and grade II Furcation involvement using mineral trioxide aggregate and platelet rich fibrin: A clinical report.

To report the management of an iatrogenic perforation of pulpal floor in the furcation of mandibular first molar, using Mineral Trioxide Aggregate (MTA) and platelet rich fibrin (PRF). Unpredictable endodontic root/pulp chamber floor perforations resulting in unacceptable high rate of clinical failure has now been a lesser threat with the advent of new technologies and biocompatible materials that utilize the applications of basic research along with tissue engineering concept in clinical practice. Present case report illustrates the use of MTA and platelet rich fibrin (PRF) for the repair of the perforation defect and regeneration of the lost periodontium in furcation area. Although, histologic events and reaction of MTA with PRF is not studied so far, however, the autologous and biocompatible nature of the components used for present treatment modalities seems to be beneficial for the long term clinical results obtained in our case.

Management of a dentigerous cyst in a medically compromised geriatric patient: a case report.

BACKGROUND: Because of the increasing number of older persons seeking dental care, the growing trend towards a longer dental appointment and increased administration of drugs in dentistry, the possibility of occurrence of medical emergencies in dental offices has shown an upward trend. OBJECTIVE: This case report discusses enucleation of a central dentigerous cyst in a 72-year old male on long-term low dose aspirin therapy. MATERIAL AND METHODS: Surgical removal of impacted tooth with total enucleation of cystic lesion was performed in the dental chair under 2% lidocaine with 1:200,000 adrenaline, 3 days after aspirin cessation. After complete debridement of the surgical site, the wound was sutured and a gauge saturated with 10% tranexamic acid was placed on surgical site for 30 minutes. RESULT: No post-operative complications or bleeding was seen on subsequent appointment and healing was normal. CONCLUSION: A geriatric and medically compromised patient demands special care and attention; and the decision to cease aspirin before surgery or not is of critical importance.

Dens invaginatus: review, relevance, and report of 3 cases.

Dens invaginatus is a rare developmental morphoanatomical variation resulting from the infolding of the dental papilla before biological mineralization that allows the invagination of inner dental epithelium. Permanent maxillary lateral incisors are most commonly affected, and the condition is frequently bilateral, but it may also prevail in permanent maxillary central incisors. The purpose of this paper was to provide an overview of the etiopathogenesis, frequency of occurrence, and clinical and radiographic features and to discuss 3 dens invaginatus cases.

Influence of smokeless tobacco on periodontal health status in local population of north India: A cross-sectional study.

BACKGROUND: Limited studies have been published so far, which revealed the association of different types of smokeless tobacco on various periodontal health indicators, including mobility and furcation, on North Indian population. The present study has been undertaken to evaluate the effects of commonly used smokeless tobacco forms on periodontal health in Lucknow, North India. METHODS: This cross-sectional study investigated the effect of commonly used smokeless tobacco on periodontal health in local population of Lucknow, for which 2045 individuals were evaluated. Amongst them, 1069 individuals were found to be using some kind of tobacco; amongst the tobacco users, n=122 were smokers, n=657 were only using only smokeless tobacco and n=290 were using both smokeless tobacco as well as tobacco in smoking form. After completing the questionnaire, all the participants underwent clinical examination for the various clinical parameters. RESULTS: The impact of smokeless form of tobacco use was significantly higher on all the periodontal health indicators, viz., plaque index, gingival index, calculus, clinical attachment loss, gingival recession, mobility, furcation, lesion, and probing pocket depth. Both duration and frequency of smokeless tobacco use significantly affected the periodontal health. CONCLUSION: The periodontal health of the general population in the region required immediate attention as majority of subjects irrespective of their habit status had onset of clinical attachment loss and gingival recession, more so amongst the smokeless tobacco users than smoking form of tobacco as well as than from non-tobacco users.

Mucogingival surgery: where we stand today.

Mucogingival problems are developmental and acquired aberrations in the morphology, position, and/or the amount of gingiva surrounding teeth. According to an academic report by American Academy of Periodontology, mucogingival therapy should be advocated for gingival augmentation and to create adequate vestibular depth in areas with insufficient attached gingiva. This paper provides an overview on mucogingival surgical procedures from its inception to the current time.

Bridge flap technique as a single-step solution to mucogingival problems: A case series.

Shallow vestibule, gingival recession, inadequate width of attached gingiva (AG) and aberrant frenum pull are an array of mucogingival problems for which several independent and effective surgical solutions are reported in the literature. This case series reports the effectiveness of the bridge flap technique as a single-step surgical entity for increasing the depth of the vestibule, root coverage, increasing the width of the AG and solving the problem of abnormal frenum pull. Eight patients with 18 teeth altogether having Millers class I, II or III recession along with problems of shallow vestibule, inadequate width of AG and with or without frenum pull underwent this surgical procedure and were followed-up till 9 months post-operatively. The mean root coverage obtained was 55% and the mean average gain in width of the AG was 3.5 mm. The mean percentage gain in clinical attachment level was 41%. The bridge flap technique can be an effective single-step solution for the aforementioned mucogingival problems if present simultaneously in any case, and offers considerable advantages over other mucogingival surgical techniques in terms of simplicity, limited chair-time for the patient and the operator, single surgical intervention for manifold mucogingival problems and low morbidity because of the absence of palatal donor tissue.

A proposal for classification of tooth fractures based on treatment need.

Accuracy in defining a disease makes it easier to study and understand. Similarly, with injuries to the teeth, a comprehensive classification is an aid to correct diagnosis and treatment planning. A thorough review of various classifications of tooth fractures shows that, despite an emphasis on traumatic dental injuries, a consensus needs to be arrived at, especially among clinicians and general/family dentists. The ideal classification would be applicable to both primary and permanent dentition, based on tooth fractures in both the horizontal and vertical planes, encompassing all possible sites, easy to comprehend, communicable amongst health professionals and clinically relevant. With recent improvements in conservative techniques, it is now clinically possible to preserve natural teeth even if they have been horizontally or vertically fractured, and thus an in-depth understanding and knowledge of tooth fractures, together with a simplified classification, is now more than ever essential.

Endosseous dental implant vis-à-vis conservative management: Is it a dilemma?

To overview the current prospective of endosseous dental implant and conservative management. Although emphasis has been made in reinstating the oral functions, less consideration has been given to formulate the best treatment tactics in a particular situation. Properly restored, root canal treated natural teeth surrounded by healthy periodontium tissues yield a very high longevity, and periodontally compromised teeth that are treated and maintained regularly may have longer survival rate. Current trends in implantology have weakened the conservative paradigm, and practitioner's objectivity has been inclined more toward providing the tooth substitutes often flaunted as equal or even superior to conservation of natural tooth.

Tooth polishing: Relevance in present day periodontal practice.

Time has seen the emergence of more efficient and effective devices like jet abrasives. However, the role of rubber cups with prophy angles cannot be overlooked as they are still being widely used and provide an economical alternative. Owing to several shortcomings associated with the air polishing device using sodium bicarbonate (NaHCO(3)), trends are shifting towards the usage of low abrasive powders. Recent demonstration of Glycine Powder Air Polishing (GPAP) in removing subgingival biofilm results in less gingival erosion than hand instrumentation or NaHCO(3) air-polishing. Despite the emergence of latest advances in polishing, data suggesting selective polishing of teeth is compelling.

Application of ultrasound in periodontics: Part II.

Ultrasound offers great potential in development of a noninvasive periodontal assessment tool that would offer great yield real time information, regarding clinical features such as pocket depth, attachment level, tissue thickness, histological change, calculus, bone morphology, as well as evaluation of tooth structure for fracture cracks. In therapeutics, ultrasonic instrumentation is proven effective and efficient in treating periodontal disease. When used properly, ultrasound-based instrument is kind to the soft tissues, require less healing time, and are less tiring for the operator. Microultrasonic instruments have been developed with the aim of improving root-surface debridement. The dye/paper method of mapping ultrasound fields demonstrated cavitational activity in an ultrasonic cleaning bath. Piezosurgery resulted in more favorable osseous repair and remodeling in comparison with carbide and diamond burs. The effect of ultrasound is not limited to fracture healing, but that bone healing after osteotomy or osteodistraction could be stimulated as well.
