Abstract
Periodontal diseases comprise a wide range of inflammatory conditions that affect the supporting structures of the teeth (the gingiva, bone and periodontal ligament), which could lead to tooth loss and contribute to systemic inflammation. Chronic periodontitis predominantly affects adults, but aggressive periodontitis may occasionally occur in children. Periodontal disease initiation and propagation is through a dysbiosis of the commensal oral microbiota (dental plaque), which then interacts with the immune defences of the host, leading to inflammation and disease. This pathophysiological situation persists through bouts of activity and quiescence, until the affected tooth is extracted or the microbial biofilm is therapeutically removed and the inflammation subsides. The severity of the periodontal disease depends on environmental and host risk factors, both modifiable (for example, smoking) and non-modifiable (for example, genetic susceptibility). Prevention is achieved with daily self-performed oral hygiene and professional removal of the microbial biofilm on a quarterly or bi-annual basis. New treatment modalities that are actively explored include antimicrobial therapy, host modulation therapy, laser therapy and tissue engineering for tissue repair and regeneration.

Abstract
ABSTRACT
Objective
To determine whether dental implants impress oral lesions, and to evaluate the nature of their effect on the lesions.
Materials and methods
A comprehensive search was done via Google and PubMed for articles (including case reports and literature reviews) containing the keywords ‘oral squamous cell carcinoma’ (OSCC), ‘oral lichen planus’ (OLP), ‘lichenoid contact reaction’ (LCR), ‘osseointegrated implants’, and ‘dental implants’, in the last 10 years (2002-2012).
Results
The study included 24 articles involving patients with dental implants, and some oral lesions (e.g. oral lichen planus and oral squamous cell carcinoma) or with a history of lesions. In these publications, there is evidence suggesting the possibility of emergence, exacerbation, recurrence, or even malignant transformation of the oral lesions after implant placement in some cases.
Conclusion
Based on our review of the literature, implant treatment does not seem to be completely safe under any circumstances, but may have some complications in subjects with certain diseases (e.g. oral lesions, autoimmune diseases, malignancies, allergic reactions, etc.). Therefore prior to treatment, patients should be fully informed of the risks.
Clinical significance
Implant treatment is best done with caution in patients with cancer or mucocutaneous disorders.

Abstract
AIMS To better quantify oral pre-trigeminal neuralgia (PTN) symptoms, attempt to identify PTN symptoms that could reliably differentiate between PTN and odontogenic tooth pain, and determine whether an anesthetic test would reliably differentiate these disorders. METHODOLOGY This was accomplished through a survey of symptom recall for 49 trigeminal neuralgia patients who had PTN tooth and/or gum pain. RESULTS The variability of oral PTN symptoms, factors that worsened or improved them, and how dental anesthesia affected them, explain the reason for variations found in the literature. A throbbing pain quality is not in the literature, but present for 63% of respondents. CONCLUSIONS No specific PTN symptom would reliably differentiate PTN from odontogenic tooth pain. The results also suggest that an anesthetic test would not be totally reliable for differentiating these disorders. A protocol is provided that should help practitioners identify the tooth pain source when there is no dental pathology.

Abstract
OBJECTIVES The molecular mechanism for the regression of pregnancy pyogenic granuloma after parturition remains unclear. It has been proposed that, in the absence of vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) causes blood vessels to regress. Therefore, we investigated the roles of Ang-2 and VEGF in the regression of pregnancy pyogenic granuloma. MATERIALS AND METHODS The effects of tumor necrosis factor-alpha (TNF-alpha) on the transcription of Ang-2 were tested in endothelial cells by reverse transcriptase-polymerase chain reaction. A total of 15 specimens, including granulomas taken from five gravidas during pregnancy, five after parturition, and five from normal gingiva were compared by immunoblot assays for their relative expressions of Ang-1, Ang-2, Tie-2, VEGF, and beta-actin. Double staining, immunohistochemistry for Ang-2, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling for apoptotic cells, were used to evaluate their regression. Finally, a fibrin gel culture system was used to investigate whether the withdrawal of VEGF and addition of Ang-2 could cause newly grown microvessels to regress. RESULTS TNF-alpha upregulated the expression of Ang-2 in all endothelial cell types tested. The protein levels of Ang-2 and Tie-2 were highest in the granulomas in pregnancy, followed by those after parturition and normal gingiva, while Ang-1 and beta-actin exhibited no significant differences. The amount of VEGF was high in the granulomas in pregnancy and almost undetectable after parturition. Double staining on granulomas after parturition revealed more apoptotic cells and less Ang-2 than did those in pregnancy. In the fibrin gel assay, VEGF alone or in combination with Ang-2 could protect microvessels from apoptosis, while Ang-2 alone had no effect. CONCLUSIONS Our findings suggest that a lack of VEGF is associated with apoptosis of endothelial cells and regression of granuloma. The roles of Ang-2 require additional study.

Abstract
BACKGROUND Space-maintaining capacity, cell disclusive potential, and stability over time are crucial factors to achieving sufficient bone augmentation with membrane barriers. The case series presented here assessed a new collagen barrier used in bone augmentation. Clinically, the healing pattern, especially in cases of secondary healing, was studied. METHODS Soft tissue healing was documented by photographs, and the size of the dehiscences calculated by image analysis. The measurements were performed on digitized photographs. During reentry, barrier remnants were dissected and histologically evaluated. RESULTS The mean value for dehiscences was 35.5 mm2; all dehiscences healed within 4 weeks after the exposure became evident. The difference was statistically significant between the week 2 and week 6 visits (P = 0.008) for each previously exposed site. The histologic observation of barrier remnants revealed direct apposition of fibrous and bone tissues on the membrane surface. CONCLUSION In cases of membrane exposure, gingival dehiscences always disappeared in the following weeks without affecting the healing process. Histologic results showed barrier stability over a 6-month period, promoting bone regeneration.

Abstract
BACKGROUND This is the first known case report that used a polymerase chain reaction (PCR)-based method to help identify the oral microflora in patients with chronic neutropenia. In this study, we report clinical periodontal findings and microflora profiles of 2 children, 1 with severe congenital neutropenia (SCN, Kostmann type) and 1 with cyclic neutropenia (CN). METHODS The SCN patient had severe gingivitis, whereas the patient with CN had mild gingivitis in the gingival margins. Monthly oral cleaning instruction and review were performed without subsequent periodontal therapy. Oral hygiene conditions remained satisfactory and visible plaque was scarce, despite the persistence of mild gingivitis. Under supervised oral hygiene, we examined the presence of periodontal pathogens from patient plaque samples. RESULTS By a PCR-based method, Prevotella nigrescens, Bacteroides forsythus, Campylobacter rectus, and Capnocytophaga gingivalis were detected in the SCN patient and P. intermedia, C. rectus, C. gingivalis, and C. sputigena in the CN patient, suggesting the existence of periodontal pathogens. Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, and C. ochracea were not found in either patient. CONCLUSIONS Use of 1% povidone iodine solution and local antibiotic application under supervised oral hygiene were helpful to improve gingival conditions in patients with chronic neutropenia.

Abstract
The condition of delayed or altered passive eruption exists in adults when the gingival unit remains positioned on the convex prominence of the enamel rather than at or in proximity to the cementoenamel junction. Treatment protocol is based on periodontal, esthetic, and prosthetic considerations. In addition, the gingival/osseous relationship becomes important for proper diagnosis and treatment. The purpose of this article is to increase awareness of the pathognomonic signs and symptoms of delayed passive eruption so that appropriate treatment can be rendered.

Abstract
The nature of the relationship between smoking and periodontal disease is not clear. However, from the information available today, the evidence, when carefully weighted, strongly suggests that smoking exerts a substantial and detrimental effect on periodontal health and disease. It is associated with an increased disease rate in terms of periodontal bone loss, attachment loss as well as periodontal pocket formation and it seems to worsen the host's defense by means of its major metabolite, nicotine. Nevertheless, new, sensitive and adequate investigations should be developed and performed in order to better explain the pathogenic mechanisms.

Abstract
Basic fibroblast growth factor (bFGF) is thought to play an important role in wound healing. However, its histological localization, both in normal and pathological conditions in the oral mucosa, has not been well documented. We have studied the immunolocalization of bFGF in normal gingiva and gingival epulis specimens corresponding to different organizing stages. In normal gingiva, bFGF was detected in subpopulations of macrophages, mast cells and most endothelial cells in the lamina propria. Granulation tissue in epulides was histopathologically classified into six organizing stages. In stages 1 and 2, a small number of bFGF-positive macrophages was seen at the periphery of ulcer bases. In stages 3 and 4, histologically characterized by prominent capillary proliferation, large numbers of bFGF-positive macrophages and mast cells were located within granulation tissue. A positive reaction for bFGF was also found in some endothelial cells and in myxoedematous stroma that was rich in heparan sulfate proteoglycan. In stages 5 and 6, when fibrosis was accelerated, bFGF-positive macrophages and mast cells decreased in number and were localized only at the periphery of the fibrous tissue. These findings suggest that maximum amounts of bFGF are synthesized and released from some macrophages and mast cells into the extracellular matrix during neovascularization of granulation tissue.

Abstract
This communication reviews the effects of short-chain carboxylic acids on human cells of importance to the periodontium. The central hypothesis is that these acids can alter both cell function and gene expression, and thus contribute to the initiation and prolongation of gingival inflammation. Short-chain carboxylic acids [CH3-(CH2)x-COOH, x < 3] are metabolic intermediates with a broad range of apparently paradoxical biological effects. For example, lactic acid (CH3-CHOH-COOH), a 3-carbon alpha-hydroxy-substituted acid, is widely recognized for its cariogenicity. Lactic acid, however, also occurs in tropical fruits, and is the active ingredient in a variety of anti-wrinkle creams developed by dermatologists. In marked contrast, the unsubstituted 3-carbon propionic acid (CH3-CH2-COOH) is used as a food preservative and is the active principle for one class of non-steroidal anti-inflammatory agents. Interestingly, the addition of one carbon to propionic acid dramatically changes the biological effects. The unsubstituted 4-carbon butyric acid (CH3-CH2-CH2-COOH) is used by hematologists as a de-differentiating agent for the treatment of sickle cell anemia, but by oncologists as a differentiating agent for cancer chemotherapy. Finally, acting either individually or in concert, these acids can increase vascular dilation. Clearly, these acids, while metabolically derived, have a number of very divergent activities which are cell-type-specific (Fig. 1). It may be telling that periodontal bacteria produce these acids in millimolar concentrations, and that these bacteria can be characterized by their acid production profiles. It is no less interesting that these acids occur in the gingival crevices of human subjects with severe periodontal disease at millimolar levels which are > 10-fold higher than those found in mildly diseased subjects, and are undetectable in healthy subjects. Further, when applied directly to healthy human gingiva, short-chain carboxylic acids stimulate a gingival inflammatory response and inflammatory cytokine release. At the cellular level, these acids inhibit proliferation of gingival epithelial and endothelial cells, and inhibit leukocyte apoptosis and function, but can stimulate leukocyte cytokine release. At the molecular level, these acids can stimulate neutrophil gene transcription, translation, and protein expression. Thus, the likelihood is high that these acids, in addition to their cariogenic activity, can promote and prolong gingival inflammation. Our challenge will be to identify the cell or cells of the periodontium which respond to short-chain carboxylic acids, to delineate their responses and the molecular mechanism(s) of these effects, and to categorize the aspects of the inflammatory components which damage and those which protect the host. With this information, it may be possible to begin to rationally identify and test pharmaceutical agents which diminish the harmful aspects, while enhancing the beneficial components, of the inflammatory response.

Abstract
Over a 10-year period a uniform management plan for patients receiving long term oral anticoagulation therapy for prosthetic heart valves and needing dental procedures was instituted. Those undergoing dental extraction or gum hygiene in the presence of gross gum pathology (Group A) had their oral anticoagulation discontinued two days prior to the procedure which was carried out only if the INR was 1.5 or less on the day of the procedure. Patients who needed dental fillings or gum hygiene in the absence of gross gum pathology (Group B) continued their anticoagulation therapy and had these procedures completed provided the INR was 3.0 or less. The main outcome measured were valve thrombosis, thromboembolism and excessive bleeding requiring hospitalization and/or blood transfusion. In Group A, 240 procedures were carried out; 212 dental extractions and 28 dental hygiene in the presence of gross gum pathology. They had a brief period of under-anticoagulation (3-7 days) to an INR of 1.5 or less. In Group B, 156 procedures were performed. No patient developed valve thrombosis or thromboembolism. Two patients, both in Group A needed hospitalization for observation but no blood transfusion. This management plan was easy to implement. Patients needed one extra visit to the anticoagulation clinic within one week of the procedure. It was both safe and effective.

Abstract
Inflammatory and immune responses involve close contact between different populations of cells. These adhesive interactions mediate migration of cells to sites of inflammation and the effector functions of cells within the lesions. Recently, there has been significant progress in understanding the molecular basis of these intercellular contacts. Blocking interactions between cell adhesion molecules and their ligands has successfully suppressed inflammatory reactions in a variety of animal models in vivo. The role of the host response in periodontal disease is receiving renewed attention, but little is known of the function of cell adhesion molecules in these diseases. In this review we summarize the structure, distribution, and function of cell adhesion molecules involved in inflammatory/immune responses. The current knowledge of the distribution of cell adhesion molecules is described and the potential for modulation of cell adhesion molecule function is discussed.

Abstract
OBJECTIVE To assess the influence of type II diabetes and impaired glucose tolerance on dental, periodontal, and oral mucosal tissues. RESEARCH DESIGN AND METHODS We examined 11 subjects with type II diabetes, 32 with impaired glucose tolerance, and 43 control subjects from the oral physiology component of the Baltimore Longitudinal Study of Aging. At the time of the study, none of the participants was taking medication nor being treated for any medical problems other than diabetes. RESULTS Only a few statistically significant dental and periodontal changes were apparent in the group with type II diabetes, and no oral mucosal differences existed between the diabetes and control groups. Dental, periodontal, and oral mucosal parameters in patients with impaired glucose tolerance were essentially indistinguishable from the other two groups. CONCLUSIONS These findings suggest that among well-controlled individuals with type II diabetes and impaired glucose tolerance, few appreciable differences are evident in oral health.

Abstract
Some of the oral health problems of older adults arise from loss of function, which is catalyzed by changes in oral health induced by systemic disease and its treatment. The successful maintenance of a healthy gingival to root surface interface depends on the development of appropriate dental and gingival contours to facilitate self-cleansing and proper hygiene procedures by the patient. This article, with the use of case histories, discusses only one of the complications to restorative care in older adults, that is, loss of function and its relationship to marginal placement. Prevention of oral disease in the older adult may require modification of the long-held periodontal/restorative philosophy of placing margins above the tissue wherever possible. In addition, the professional prophylaxis of restorations adjacent to the gingival margin must address the problems of the creation of a roughened surface by abrasion to composites from pastes and polishing.

Abstract
The long-term effect of increased local venous pressure (Pv) on interstitial fluid pressure (Pi), colloid osmotic pressure (COPi), and fractional removal rate of 125I-labeled human serum albumin (kAlb) was studied in rat gingiva. Measurements were performed on experimental animals and sham-operated controls up to 4 days after ligation of jugular veins. On the day of ligation Pv in the facial veins rose from 2.5 +/- 0.3 (SD) to 15.8 +/- 2.8 mm Hg and stayed at about this level for 2 days before a decrease to 7.4 +/- 0.9 mm Hg on day 4. In free gingiva Pi rose from an average of 3.5 +/- 0.4 to a maximum of 6.3 +/- 0.7 mm Hg, whereas in attached gingiva the corresponding increase in Pi was from 6.0 +/- 0.7 to 11.1 +/- 2.1 mm Hg. One day after the ligation COPi in wick fluid from gingiva was reduced from the control level of 10.6 +/- 1.4 to 4.5 +/- 0.9 mm Hg. COP in plasma and COPi in subcutaneous tissue on the back were unaffected. The removal rate of 125I-labeled albumin (kAlb) from the gingiva showed a nearly threefold increase after venous ligation, from 0.073 +/- 0.01 to 0.211 +/- 0.06 h-1. It is concluded that in free and attached gingiva, both a rise in Pi and a decrease in COPi will counteract the increased filtration pressure and thus prevent edema formation during venous stasis. The fall in COPi is most likely due to increased lymph flow and not dilution, as venous stasis significantly increased kAlb without any visible increase in gingival volume.

Abstract
This paper describes levels and progression of supra- and subgingival calculus undisturbed by active professional intervention or home care between 1970 and 1985 in Sri Lanka, or when removed at regular intervals between 1969 and 1988 in Norway. In the Sri Lankan tea laborers, both supra- and subgingival calculus formation started before age 14 years. At 40 years of age, all participants and almost all teeth and tooth surfaces had calculus. Tea laborers who both smoked tobacco and chewed betel had significantly higher calculus scores than those who only had one of these habits, and those who neither chewed nor smoked had the lowest calculus scores. Teeth with calculus showed a significantly higher rate of loss of attachment than teeth that remained calculus free. For the Norwegians who had enjoyed regular dental care throughout their lives, supragingival calculus did not increase in frequency from adolescence to the forties. Approximately 70% of the interproximal surfaces were calculus free after 40-50 years of age. Subgingival calculus scores, although low, showed some increase with longer times of exposure. On average, each person had 0.4 interproximal surfaces with subgingival calculus as they approached 50 years of age. In this Norwegian population, subgingival calculus had no impact on loss of attachment.

Abstract
This study monitored the development and repair of interdental soft tissue defects following surgical treatment of periodontitis in 21 patients. Open flap curettage was performed at 100 interdental areas with follow-up examinations 1, 3, and 6 months later. Interdental gingival contours were assessed both clinically and indirectly with silicone elastomer impressions from which stone models were obtained; defect depths were then calculated using the Reflex Microscope. Two types of defect were identified at the 1-month follow-up: 13 interdental clefts (mean depth, 1.8 mm); and 30 craters, (mean depth, 1.6 mm). Although clefts tended to persist, craters showed a strong tendency to repair. Thus, at the 6-month follow-up, the depths of clefts and craters were 1.3 mm and 0.7 mm respectively. The development of soft tissue defects did not appear to be related to the use of a periodontal dressing nor did the existence of an underlying bone defect appear to be of etiological importance. Pre-operative probing depths, however, were positively associated with the occurrence of soft tissue craters (P = 0.02). Pre-operatively, the overall mean probing depth and frequency of bleeding on probing were 5.3 mm and 100% respectively. At 6 months, these values were reduced to 2.0 mm and 22%. When clefts, craters, and interdental areas with no soft tissue defect were compared, no significant differences in probing depth reduction or frequency of bleeding were observed at any time point.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Understanding of wound healing mechanisms is important in designing preventive and therapeutic approaches to inflammatory periodontal diseases, which are a major cause of dental morbidity. In this study, cell proliferation was assessed after an experimental gingival wound; this was preceded by either resection of 3 mm of the inferior alveolar nerve, total extirpation of the superior cervical ganglion, trauma to those structures or sham operations. At different times, animals were pulsed with 0.5 microCi/g body weight of tritiated thymidine; histological sections were processed for quantitative autoradiography of different compartments of the periodontium. Wounding led to a significant increase in cell proliferation in the epithelial layer, the fibroblast compartment and the periodontal ligament, but not in the alveolar crest compartment. Sympathetic denervation significantly enhanced this response in the epithelial layer, the fibroblast compartment and the alveolar crest, whereas sensory denervation only modified the response in the fibroblast layer. Thus it appears that sympathetic innervation plays an important role in the regulation of cell proliferation in the periodontium and that pharmacological modulation of sympathetic activity should be further studied as a therapeutic approach in periodontal disease.

Abstract
Numerous papers on epithelial jaw cysts have appeared in the decade since the publication in 1971 of the WHO histological classification of odontogenic tumours, jaw cysts, and allied lesions. Despite clarification of certain cyst varieties no major revisions are necessary. The following minor modifications are proposed. In the developmental odontogenic group, the terms keratocyst and follicular are preferred to primordial and dentigerous. The alveolar cyst of infants is categorised separately from the gingival cyst of adults. The developmental lateral periodontal cyst is included as a distinctive new type. In the non-odontogenic group the globulomaxillary is deleted as a unique entity, whereas the midpalatal cyst of infants is a new inclusion. To the inflammatory category are added the inflammatory follicular and inflammatory lateral periodontal varieties.

Abstract
In order for successful coverage of denuded roots to be accomplished, correctly applied fundamental biological principles must be considered in the choice and utilization of the surgical modality. In this report some representative clinical cases are presented to indicate favorable results that may be achieved with stimulated osteoperiosteal pedicle flaps. These cases are part of an ongoing clinical and statistical evaluation.

Abstract
A 48-year-old female patient presented with advanced periodontitis but was unable to proceed with periodontal therapy. After ten years of absence, her periodontal status appeared unchanged, if not slightly improved, despite the total lack of any dental or periodontal care. Studies on the biologic behavior of periodontitis are severely lacking and would appear to be a logical area for future epidemiologic surveys.

Abstract
The effect of some agents on the antimicrobial activity of ammoniacal silver nitrate, an endodontic medicament, was tested with Streptococcus faecalis by the serial tube dilution method. Its results indicated that sodium hypochlorite, hydrogen peroxide, and blood had a marked inhibitory effect. However, the presence of dentin, necrotic tissue, saliva, and hydrogen sulfide gas liberated from protein decomposition showed no or little effect on the antibacterial properties of the chemical. Since antiseptics or antibiotics generally may be decomposed by necrotic tissues, these findings suggested that the use of ammoniacal silver nitrate not only may resolve the problem of recalcitrant cases in endodontic treatment but also may simplify the disinfecting procedure for root canals.

Abstract
Three cases have been presented illustrating the complications which may arise from the use of electrosurgery. These cases provide clinical evidence of the potential for severe periodontal destruction, a potential that must be weighed carefully by any practitioner who uses an electrosurgical instrument. It is suggested that new scientific studies be initiated to establish basic principles that will eliminate the hazards that now exist in the routine use of electrosurgery.
