Whelan J, Ghoniem M, Médoc N, Apicella M, Beck E. Applying a novel approach to scoping review incorporating artificial intelligence: mapping the natural history of gonorrhoea. BMC Med Res Methodol 2021; 21:183. [PMID: 34488645 PMCID: PMC8418964 DOI: 10.1186/s12874-021-01367-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Accepted: 08/02/2021] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Systematic and scoping literature searches are increasingly resource intensive. We present the results of a scoping review which combines the use of a novel artificial-intelligence-(AI)-assisted Medline search tool with two other 'traditional' literature search methods. We illustrate this novel approach with a case study to identify and map the range of conditions (clinical presentations, complications, coinfections and health problems) associated with gonorrhoea infection. METHODS To fully characterize the range of health outcomes associated with gonorrhoea, we combined a high yield preliminary search with a traditional systematic search, then supplemented with the output of a novel AI-assisted Medline search tool based on natural language processing methods to identify eligible literature. RESULTS We identified 189 health conditions associated with gonorrhoea infection of which: 53 were identified through the initial 'high yield' search; 99 through the systematic search; and 124 through the AI-assisted search. These were extracted from 107 unique references and 21 International Statistical Classification of Diseases and Related Health Problems Ninth and Tenth Revision (ICD 9/10) or Read codes. Health conditions were mapped to the urogenital tract (n = 86), anorectal tract (n = 6) oropharyngeal tract (n = 5) and the eye (n = 14); and other conditions such as systemic (n = 61) and neonatal conditions (n = 7), psychosocial associations (n = 3), and co-infections (n = 7). The 107 unique references attained a Scottish Intercollegiate Guidelines Network (SIGN) score of ≥2++ (n = 2), 2+ (14 [13%]), 2- (30 [28%]) and 3 (45 [42%]), respectively. The remaining papers (n = 16) were reviews. CONCLUSIONS Through AI screening of Medline, we captured - titles, abstracts, case reports and case series related to rare but serious health conditions related to gonorrhoea infection. These outcomes might otherwise have been missed during a systematic search. The AI-assisted search provided a useful addition to traditional/manual literature searches especially when rapid results are required in an exploratory setting.

Abstract
Oral health is an integral part of the general health and well-being of individuals. The presence of oral disease is potentially indicative of a number of systemic diseases and may contribute to their early diagnosis and treatment. The ubiquitin (Ub) system has been shown to play a role in cellular immune response, cellular development, and programmed cell death. Ubiquitination is a post-translational modification that occurs in eukaryotes. Its mechanism involves a number of factors, including Ub-activating enzymes, Ub-conjugating enzymes, and Ub protein ligases. Deubiquitinating enzymes, which are proteases that reversely modify proteins by removing Ub or Ub-like molecules or remodeling Ub chains on target proteins, have recently been regarded as crucial regulators of ubiquitination-mediated degradation and are known to significantly affect cellular pathways, a number of biological processes, DNA damage response, and DNA repair pathways. Research has increasingly shown evidence of the relationship between ubiquitination, deubiquitination, and oral disease. This review investigates recent progress in discoveries in diseased oral sites and discusses the roles of ubiquitination and deubiquitination in oral disease.

Abstract
Background While inflammatory diseases such as gingivitis and periodontitis induced by dental plaque biofilms constitute the majority of gingival lesions, gingiva can also be affected by a variety of diseases with aetiologies different from bacterial biofilms. The aim of this study was to retrospectively analyze the frequency and distribution of non-dental plaque-induced gingival diseases (NDPIGDs) in the Chinese population in a single institute. Methods A total of 6859 samples of biopsied gingival diseases during the period 2000–2019 were obtained from the Department of Pathology, Peking University Hospital of Stomatology. Lesions were categorized by histopathological diagnosis, pathological characteristics and the new classification of gingival health and gingival diseases/conditions. Demographic information, such as gender, location, and age, were also analyzed. Results Among 6859 biopsied NDPIGD samples, the five most frequent diagnoses included oral squamous cell carcinoma (OSCC, n = 2094), fibrous hyperplasia (n = 2026), pyogenic granuloma (n = 478), epithelial dysplasia (n = 477), and epithelial hyperplasia/hyperkeratosis (n = 436). All types could be grouped into nine categories according to their pathological characteristics. The most common biopsied NDPIGDs category was “hyperplastic lesions” (n = 2648, 38.61%), followed by “malignant neoplasms” (n = 2275, 33.17%). The most common diagnosis types in each category were fibrous hyperplasia and OSCC. Of all NDPIGDs, most lesions could be categorized into the new classification of gingival health and gingival diseases/conditions; only 7.07% did not fit the current classification system. Conclusions The present study is the first report on the frequency and distribution of biopsied NDPIGDs in a Chinese population. Unlike previous studies, the most prevalent categories were “hyperplastic lesions” and “malignant neoplasms”. The proportion of “malignant neoplasms” and “oral potentially malignant disorders” was remarkably higher than in previous researches. Nevertheless, the study provided epidemiological information on many NDPIGDs, which could be useful for future health policies as well as screening programs.

Abstract
With the advent of combined antiretroviral therapies, the face of HIV infection has changed dramatically from a disease with almost certain mortality from serious comorbidities, to a manageable chronic condition with an extended lifespan. In this paper we present the more recent investigations into the epidemiology, microbiology, and pathogenesis of periodontal diseases in patients with HIV, and the effects of combined antiretroviral therapies on the incidence and progression of these diseases both in adults and perinatally infected children. In addition, comparisons and potential interactions between the HIV-associated microbiome, host responses, and pathogenesis in the oral cavity with the gastrointestinal tract and other areas of the body are presented. Also, the effects of HIV and combined antiretroviral therapies on comorbidities such as hyposalivation, dementia, and osteoporosis on periodontal disease progression are discussed.

Abstract
Many soft-tissue grafting solutions are available for reconstruction and restoration of volume and esthetics of keratinized attached mucosa at compromised periodontal and peri-implant interfaces. Presence of healthy soft tissues is crucial for functional and esthetic implant success as well as longevity of natural dentition. The options available each provide unique characteristics with different indications. This article is intended to provide an efficient and comprehensive overview of this topic, covering the essentials of periodontal anatomy and physiology, indications for soft-tissue grafting, and keys in recipient and donor-site preparation, and exploring the available procedural arsenal in soft-tissue grafting.

Abstract
Periodontitis and gingivitis are highly prevalent inflammatory diseases of the oral cavity, and typically are characterised by the presence of dental plaque. However, other causes of oral inflammation exist, which can resemble plaque-induced gingivitis and periodontitis, and may thus first be seen by a dental practitioner. This paper aims to provide dentists with an understanding of the manifestations of systemic diseases to the periodontium and highlights anamnestic and clinical clues important for distinguishing between plaque-induced and non plaque-induced lesions. In the first part of this series immune-mediated and hereditary conditions as causes of gingival lesions were discussed; this second part highlights cancer-related gingival lesions as well as those caused by specific pathogens, medication or malnutrition. A clear clinical, epidemiological and visual overview of the different conditions is provided. Early diagnosis of non plaque-related causes of gingival lesions can be vital for affected patients. Therefore, dental practitioners should be aware of the various manifestations of systemic diseases to the periodontium.

Abstract
BACKGROUND AND OBJECTIVE The study compared clinical and patient-centered outcomes of subepithelial connective tissue graft (CTG) with and without enamel matrix derivative (EMD) in the treatment of Class I-II Miller periodontal recession defects. MATERIAL AND METHODS This prospective clinical study evaluated 80 patients over a 3 years follow-up in a private periodontal practice. A total of 144 maxillary and mandibular anterior teeth were divided into two groups: group 1 (CTG with EMD-80 teeth) and group 2 (CTG only-64 teeth). Recession (REC), keratinized tissue (KT) width, % root overage, patient-centered outcomes, and pain visual analog scale (P-VAS) were compared between the two groups. RESULTS At 3 years follow-up at a patient level, statistically significant changes in REC were achieved in both group 1 (4.65 ± 1.84 to 0.39 ± 0.19 mm) and group 2 (4.43 ± 1.11 to 0.92 ± 0.43 mm). Complete root coverage (CRC) was achieved in 66.4% of group 1 and 50.1% of group 2. At both patient and tooth level, the 3-year outcomes were superior for group 1 compared with group 2 in terms of % root coverage, REC, and KT width. Clinical attachment loss (CAL) was reduced in group 1 compared with group 2 at the tooth level analysis only (<.01). Significantly less pain was reported using the pain visual analog Scale (P < .001) at the two weeks follow-up post-surgery in group 1. CONCLUSIONS Addition of EMD results in improved root coverage outcomes and higher amounts of keratinized tissue width 36 months after treatment of multiple adjacent recessions on maxillary and mandibular anterior teeth. The adjunctive use of EMD also resulted in significantly reduced pain 14 days after the surgery.

Abstract
While plaque-induced gingivitis is one of the most common human inflammatory diseases, several non-plaque-induced gingival diseases are less common but often of major significance for patients. The non-plaque-induced gingival lesions are often manifestations of systemic conditions, but they may also represent pathologic changes limited to gingival tissues. A classification is proposed, based on the etiology of the lesions and includes: Genetic/Developmental disorders; Specific infections; Inflammatory and immune conditions and lesions; Reactive processes; Neoplasms; Endocrine, Nutritional and metabolic diseases; Traumatic lesions; and Gingival pigmentation.

Abstract
Oral health has substantial economic importance, with over $100 billion spent on dental care in the United States annually. The microbiome plays a critical role in oral health, yet remains poorly classified. To address the question of how microbial diversity and function in the oral cavities of children relate to caries diagnosis, we surveyed the supragingival plaque biofilm microbiome in 44 juvenile twin pairs. Using shotgun sequencing, we constructed a genome encyclopedia describing the core supragingival plaque microbiome. This unveiled several new previously uncharacterized but ubiquitous microbial lineages in the oral microbiome. Caries is a microbial community metabolic disorder that cannot be described by a single etiology, and our results provide the information needed for next-generation diagnostic tools and therapeutics for caries. To address the question of how microbial diversity and function in the oral cavities of children relates to caries diagnosis, we surveyed the supragingival plaque biofilm microbiome in 44 juvenile twin pairs. Using shotgun sequencing, we constructed a genome encyclopedia describing the core supragingival plaque microbiome. Caries phenotypes contained statistically significant enrichments in specific genome abundances and distinct community composition profiles, including strain-level changes. Metabolic pathways that are statistically associated with caries include several sugar-associated phosphotransferase systems, antimicrobial resistance, and metal transport. Numerous closely related previously uncharacterized microbes had substantial variation in central metabolism, including the loss of biosynthetic pathways resulting in auxotrophy, changing the ecological role. We also describe the first complete Gracilibacteria genomes from the human microbiome. Caries is a microbial community metabolic disorder that cannot be described by a single etiology, and our results provide the information needed for next-generation diagnostic tools and therapeutics for caries.

Abstract
Host-associated microbial communities are influenced by both host genetics and environmental factors. However, factors controlling the human oral microbiome and their impact on disease remain to be investigated. To determine the combined and relative effects of host genotype and environment on oral microbiome composition and caries phenotypes, we profiled the supragingival plaque microbiome of 485 dizygotic and monozygotic twins aged 5-11. Oral microbiome similarity always increased with shared host genotype, regardless of caries state. Additionally, although most of the variation in the oral microbiome was determined by environmental factors, highly heritable oral taxa were identified. The most heritable oral bacteria were not associated with caries state, did not tend to co-occur with other taxa, and decreased in abundance with age and sugar consumption frequency. Thus, while the human oral microbiome composition is influenced by host genetic background, potentially cariogenic taxa are likely not controlled by genetic factors.

Abstract
Background Many gingival lesions are not induced by plaque. The aim of this study was to analyze the frequency of biopsied non-plaque-induced gingival lesions (NPIGL) in a Chilean population. Methods One thousand twelve cases of biopsied gingival lesions with confirmed anatomopathologic diagnosis were included, from the records of the Oral Pathology Referral Institute (OPRI), Faculty of Dentistry, University of Chile, between years 1990 and 2009. Results The most frequent non plaque-induced gingival lesions categories from biopsied cases included hyperplastic lesions, malignancies and benign neoplasms. The most frequent diagnoses in each category were fibrous hyperplasia (35.47%), squamous cell carcinoma (3.85%) and giant cell fibroma (2.08%), respectively. From all lesions, only 8.3% fitted in the specified categories of the current classification of periodontal diseases. Conclusions The most frequent biopsied NPIGL were hyperplastic lesions and neoplasms. These categories represent relevant lesions to be included in a future periodontal classification system to improve the care needs of the patients, as well as early diagnosis and treatment.

Abstract
Iatrogenic trauma though not serious is very common in dental practice. Orthodontic treatment can inflict such injuries as they are prolonged over a long period of time. Ill-fabricated orthodontic appliances, such as wires and brackets, or the patients' habits such as application of constant pressure over the appliance can traumatize the adjacent oral soft tissues. In rare cases, these appliances can get embedded into the mucosa and gingival tissues. This case report describes one such case of iatrogenic trauma to the palatal mucosa due to entrapment of a tongue spike appliance and its surgical management.

Ubiquitination in Periodontal Disease: A Review. Int J Mol Sci 2017; 18:ijms18071476. [PMID: 28698506 PMCID: PMC5535967 DOI: 10.3390/ijms18071476] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2017] [Revised: 07/04/2017] [Accepted: 07/05/2017] [Indexed: 12/30/2022] Open
Abstract
Periodontal disease (periodontitis) is a chronic inflammatory condition initiated by microbial infection that leads to gingival tissue destruction and alveolar bone resorption. The periodontal tissue's response to dental plaque is characterized by the accumulation of polymorphonuclear leukocytes, macrophages, and lymphocytes, all of which release inflammatory mediators and cytokines to orchestrate the immunopathogenesis of periodontal disease. Ubiquitination is achieved by a mechanism that involves a number of factors, including an ubiquitin-activating enzyme, ubiquitin-conjugating enzyme, and ubiquitin-protein ligase. Ubiquitination is a post-translational modification restricted to eukaryotes that are involved in essential host processes. The ubiquitin system has been implicated in the immune response, development, and programmed cell death. Increasing numbers of recent reports have provided evidence that many approaches are delivering promising reports for discovering the relationship between ubiquitination and periodontal disease. The scope of this review was to investigate recent progress in the discovery of ubiquitinated protein in diseased periodontium and to discuss the ubiquitination process in periodontal diseases.

Abstract
BACKGROUND Gingivitis is a highly prevalent periodontal disease resulting from microbial infection and subsequent inflammation. The efficacy of herbal preparations in subjects with gingivitis has been reported in some previous studies. OBJECTIVE To investigate the efficacy of a polyherbal mouthwash containing hydroalcoholic extracts of Zingiber officinale, Rosmarinus officinalis and Calendula officinalis (5% v/w) compared with chlorhexidine and placebo mouthwashes in subjects with gingivitis. METHODS Sixty patients participated in this randomized double-blind placebo-controlled trial and were randomly assigned to the polyherbal mouthwash (n = 20), chlorhexidine mouthwash (n = 20) or placebo mouthwash (n = 20). Participants were instructed to use the mouthwash twice a day (after breakfast and dinner) for 30 s for a period of two weeks. Gingival and plaque indices were assessed using MGI, GBI and MQH scales at baseline, day 7 and day 14 of the trial. RESULTS There were significant improvements in all assessed efficacy measures i.e. MGI, GBI and MQH scores from baseline to the end of trial in both polyherbal and chlorhexidine mouthwash groups; however, the scores remained statistically unchanged in the placebo group. MGI, BGI and MQH scores in the treatment groups were significantly lower compared with those of the control group at both day 7 and day 14 of the trial. However, there was no significant difference between the polyherbal and chlorhexidine groups, neither at day 7 nor day 14 of the trial. Polyherbal mouthwash was safe and there was neither report of adverse reactions, nor any drop-out during the course of study. CONCLUSION Polyherbal mouthwash containing hydroalcoholic extracts of Z. officinale, R. officinalis and C. officinalis (5%) was effective in the treatment of gingivitis and its efficacy was comparable to that of chlorhexidine mouthwash.

Abstract
This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute disease is under control, definitive treatment should be provided, including appropriate therapy for the pre-existing gingivitis or periodontitis. Among other acute conditions affecting the periodontal tissues, but not caused by the microorganisms present in oral biofilms, infectious diseases, mucocutaneous diseases and traumatic or allergic lesions can be listed. In most cases, the gingival involvement is not severe; however, these conditions are common and may prompt an emergency dental visit. These conditions may have the appearance of an erythematous lesion, which is sometimes erosive. Erosive lesions may be the direct result of trauma or a consequence of the breaking of vesicles and bullae. A proper differential diagnosis is important for adequate management of the case.

Abstract
We herein report a case of gingival candidiasis in an advanced gastric cancer patient while receiving palliative cytotoxic chemotherapy. A 46-year-old male patient admitted to our hospital for known advanced gastric cancer with newly developed multiple liver metastases. While receiving 2nd line cytotoxic chemotherapy with 5FU, leucovorin, and paclitxel, he complained of gingival swelling accompanied by pain and whitish plaque. Due to lack of response to the conservative oral care, incisional biopsy of gingiva was done and the pathology confirmed gingival candidiasis. Although the lesion healed apparently after two-week antifungal therapy, pain as well as bony destruction remains. By presenting this case report, we intend to emphasize the immunocompromising effect of cancer while being on systemic chemotherapy.

Abstract
Background. Since 2000, studies, experiments, and clinical observations revealed high prevalence of periodontal diseases among children and adolescents. Therefore, this paper was designed to provide an update for dental practitioners on epidemiology, microbiology, pathology, prevention, diagnosis, and treatment of periodontal diseases in children and adolescents. Methods. This paper reviews the current literature concerning periodontal diseases in pediatric dentistry. It includes MEDLINE database search using key terms: “periodontal diseases in children,” “Periodontal diseasesin adolescents,” “periodontal diseases risk factors,”
“microbiology of periodontal diseases,” “classification of periodontal diseases,” “epidemiology of periodontal diseases,” and “treatment of periodontal diseases.” Articles were evaluated by title and/or abstract and relevance to pediatric dentistry. Sixty-five citations were selected by this method and by the references within the chosen articles. A review of the comprehensive textbooks on pediatric dentistry and periodontology was done. Some recommendations were based on the opinions of experienced researchers and clinicians, when data were inconclusive.

Abstract
In the past 50 years, conceptual changes in the field of periodontal diagnostics have paralleled those associated with a better scientific understanding of the full spectrum of processes that affect periodontal health and disease. Fifty years ago, concepts regarding the diagnosis of periodontal diseases followed the classical pathology paradigm. It was believed that the two basic forms of destructive periodontal disease were chronic inflammatory periodontitis and 'periodontosis'- a degenerative condition. In the subsequent 25 years it was shown that periodontosis was an infection. By 1987, major new concepts regarding the diagnosis and pathogenesis of periodontitis included: (i) all cases of untreated gingivitis do not inevitably progress to periodontitis; (ii) progression of untreated periodontitis is often episodic; (iii) some sites with untreated periodontitis do not progress; (iv) a rather small population of specific bacteria ('periodontal pathogens') appear to be the main etiologic agents of chronic inflammatory periodontitis; and (v) tissue damage in periodontitis is primarily caused by inflammatory and immunologic host responses to infecting agents. The concepts that were in place by 1987 are still largely intact in 2012. However, in the decades to come, it is likely that new information on the human microbiome will change our current concepts concerning the prevention, diagnosis and treatment of periodontal diseases.

Abstract
The introduction of highly active antiretroviral therapy (HAART) has decreased the incidence and prevalence of several oral manifestations such as oral candidiasis, hairy leukoplakia, and Kaposi's sarcoma in HIV-infected patients. Regarding periodontal disease the findings are not clear. This disease represents a group of chronic oral diseases characterized by infection and inflammation of the periodontal tissues. These tissues surround the teeth and provide periodontal protection (the gingival tissue) and periodontal support (periodontal ligament, root cementum, alveolar bone). Clinical, immunological, and microbiological aspects of these diseases, such as linear gingival erythema (LGE), necrotizing periodontal diseases (NPD) (necrotizing ulcerative gingivitis [NUG], necrotizing ulcerative periodontitis [NUP] and necrotizing stomatitis), and chronic periodontitis, have been widely studied in HIV-infected individuals, but without providing conclusive results. The purpose of this review was to contribute to a better overall understanding of the probable impact of HIV-infection on the characteristics of periodontal infections.

Abstract
Since the early 1990's, the death rate from AIDS among adults has declined in most developed countries, largely because of newer antiretroviral therapies and improved access to these therapies. In addition, from 2006 to 2011, the total number of new cases of HIV infection worldwide has declined somewhat and has remained relatively constant. Nevertheless, because of the large numbers of existing and new cases of HIV infection, the dental practitioner and other healthcare practitioners will still be required to treat oral and periodontal conditions unique to HIV/AIDS as well as conventional periodontal diseases in HIV-infected adults and children. The oral and periodontal conditions most closely associated with HIV infection include oral candidiasis, oral hairy leukoplakia, Kaposi's sarcoma, salivary gland diseases, oral warts, other oral viral infections, linear gingival erythema and necrotizing gingival and periodontal diseases. While the incidence and prevalence of these oral lesions and conditions appear to be declining, in part because of antiretroviral therapy, dental and healthcare practitioners will need to continue to diagnose and treat the more conventional periodontal diseases in these HIV-infected populations. Finding low-cost and easily accessible and acceptable diagnostic and treatment approaches for both the microbiological and the inflammatory aspects of periodontal diseases in these populations are of particular importance, as the systemic spread of the local microbiota and inflammatory products of periodontal diseases may have adverse effects on both the progression of HIV infection and the effectiveness of antiretroviral therapy approaches. Developing and assessing low-cost and accessible diagnostic and treatment approaches to periodontal diseases, particularly in developing countries, will require an internationally coordinated effort to design and conduct standardized clinical trials.

Abstract
PURPOSE Ethanol, human papilloma virus (HPV), and poor oral hygiene are risk factors that have been attributed to oral carcinogenesis. Streptococci sp and HPV infections are common in the head and neck, often associated with sexual activity. Although HPV is linked to head and neck squamous cell carcinoma, it is unclear whether there is a similar role for Streptococci sp. This cell study examines whether Streptococci sp and HPV-16 with exposure to ethyl alcohol (ETOH) can act as cofactors in the malignant transformation of oral keratinocytes. MATERIALS AND METHODS ETOH (0.1%-20% vol/vol) was used to investigate Streptococci sp attachment with immortalized E6-expressing HPV/HOK-16B cells, human oral buccal keratinocytes, and foreskin keratinocytes. Streptococci sp (Streptococci mutans [LT11]) and various strains of acetaldehyde (AA) producer and nonproducer Streptococcus salivarius (110-1, 109-2, 101-7, and 107-1) and a lactic acid producer bacterium, Lactobacillus rhamnosus (24-1 and 25-2), were examined for interactions with keratinocytes by use of a green dye (percent of cells with colonies after 24 hours). Carcinogens, AA, malondialdehyde, DNA damage, and proliferation (5'-bromo-2-deoxyuridine) among keratinocytes were also quantified. RESULTS AA and malondialdehyde production from permissible Streptococci sp significantly increased with attachment to keratinocytes, whereas L rhamnosus did not significantly attach to keratinocytes. This attachment was associated with enhanced levels of AA adduct formation, proliferation (5'-bromo-2-deoxyuridine incorporation), and enhanced migration through integrin-coated basement membrane by HPV oral keratinocytes, which are characteristics of a malignant phenotype. CONCLUSIONS These cell studies suggest that oral Streptococci sp and HPV (HPV-16) cooperate to transform oral keratinocytes after low-level ETOH (1%) exposure. These results appear to suggest a significant clinical interaction, but further validation is warranted.

Abstract
OBJECTIVE The aim of this study was to evaluate the effectiveness of Er:YAG laser and conventional periodontal therapy in the treatment of acute streptococcal gingivitis both clinically and microbiologically. BACKGROUND DATA This case report describes a 2-year follow-up of a 30-year-old, female, chronic periodontitis patient, presenting severe gingival inflammation, sensitivity, pain, and acute gingival lesions that were treated with Er:YAG laser and conventional hand and ultrasonic instruments. MATERIALS AND METHODS Before the initial periodontal treatment, microbiological samples were taken from the lesion sites with sterile paper points from the sulcuses bilaterally, and excisional biopsies were obtained from the lesions. Following diagnostic tests, the lesions were identified as acute streptococcal gingivitis. Following the measurement of clinical indices, initial periodontal therapy was performed with Er:YAG laser on the right side and conventional hand and ultrasonic instruments on the left side, which were performed as two sessions at weekly intervals. As an adjunct to mechanical periodontal therapy, 500 mg amoxicillin was prescribed t.i.d. for a week. RESULTS Microbiological samples grew mostly Streptococcus sp. and black pigmented obligate anaerobic bacteria. The histopathological examination revealed acanthosis, papillomatosis, and spongiotic lesions in the keratinized stratified squamous epithelium; infiltration of polymorphonuclear neutrophils, lymphocytes, and macrophages and plasma cells in the connective tissue; infiltration and accumulation of polymorphonuclear neutrophils in the epithelium, especially in the spongiotic lesions; and formation of microabscess-like clusters. After the initial periodontal treatment, clinical and microbiological measurements were repeated and reductions in clinical indices and the number of microorganisms were observed. both treatment modalities gave similar results, and no recurrences were observed during the 2-year follow-up. CONCLUSION Er:YAG laser seems to be promising and as effective as conventional periodontal therapy in the treatment of acute streptococcal gingivitis.

Abstract
Lichen planus is a common mucocutaneous disease. However, lichen planus with concomitant oral and genital involvement is a rare condition that requires multidisciplinary intervention for appropriate diagnosis. In this study, we reported two cases of oro-genital lichen planus in a man and a woman. Analyses of oral and genital lesions were clinically and histopathologically compatible with lichen planus. This description highlights the importance of patients presenting oral lichen planus be routinely required to undergo further medical examination in order to investigate putative genital mucosal involvement. These lesions have the potential to progress to neoplasia. Therefore, medical and dentistry professionals should be aware of this condition.

Abstract
BACKGROUND Chronic desquamative gingivitis (DG) is a condition characterized by erythema, ulceration, and desquamation of the free and attached gingiva, usually expression of a district-systemic disease, such as oral lichen planus (OLP). METHODS A combined protocol of oral hygiene and topic corticosteroid therapy was applied in 30 patients with DG associated with OLP. Plaque index (PI) and bleeding on probing (BoP) were evaluated at baseline and after 3 months. RESULTS PI scoring was significantly lower after treatment in anterior, posterior, and all sites (P < 0.0001) as well as in vestibular and lingual ones (P < 0.0001 and P = 0.0001, respectively). BoP measures were found to be reduced significantly to 22.94% in a full-mouth evaluation (P < 0.0001; OR = 2.633; 95% CI: 2.2685-3.0561) as well as in each specific site (P < 0.0001). CONCLUSION This clinical trial validated the efficacy, in patients with DG associated with OLP, of a protocol based on professional oral hygiene and self-performed plaque control measures in improving of gingival health status.

Abstract
BACKGROUND In classic albinism, all parts of the body are normal except for the absence of melanin. It is believed that lack of this pigment in periodontal tissues might influence periodontal disease progression. This study was designed to determine the relationship between periodontal diseases and albinism by comparing the clinical periodontal status of a group of native Panamanian Kuna albinos (from San Blas, Panama) to Kuna non-albinos of the same communities. METHODS An experimental group of 30 subjects (Kuna albinos aged > or =12 years) was selected and divided into three subgroups according to age. Likewise, a control group of 30 subjects (Kuna non-albinos) was selected and divided in subgroups. RESULTS Assessment of oral hygiene and gingival inflammation in albinos by the Silness and Löe plaque index and Löe and Silness gingival index, respectively, was unremarkable compared to control groups. No statistically significant differences were found for number of teeth present, gingival index, plaque index, clinical attachment loss (CAL), probing depth, or gingival recession. As expected, age was a factor in the severity of the periodontal disease; 58% of individuals aged > or =36 years had at least one site with CAL > or =7 mm. CONCLUSION Based on the overwhelming similarity of results found between experimental and control groups, albinism does not represent a clinical risk factor in the pathogenesis or exacerbation of periodontal diseases for these individuals.

Abstract
Food intolerance is the term used to describe a hypersensitivity reaction to a food component. These reactions refer to the drug-like side effects caused by a range of chemicals that may be present in food as natural or added components. The range of symptoms which can be induced by food intolerance are very similar to those caused by food allergy, oral allergy syndrome, acute infectious diseases and vesiculobullous disorders; so that on initial presentation, it can be difficult to differentiate between these conditions. A 48-year-old woman with complaints of allergic symptoms was examined with skin prick test (SPT), specific IgE analysis, and oral challenge test for definitive allergen determination. The patient was negative in both specific IgE detection and SPT with commercial extracts of apple, whereas the oral challenge test revealed positive objective symptoms with blister and ulcer formation. Apple has been reported to be the cause of food allergy. To our knowledge, there is no report of apple intolerance in which the lesions are only confined to gingival tissues.

Abstract
BACKGROUND Iatrogenic trauma can be defined as any trauma that has been induced by the dentist's activity, manner, or therapy. The aim of this article is to present traumatic oral tissue lesions of iatrogenic origin. METHODS Thirteen cases of chemical (due to ferric sulfate and formocresol), physical (due to orthodontic wires and appliances), and thermal (due to electrosurgery) injuries to the oral tissues are reported. RESULTS Chemical, physical, and thermal injuries in the oral, gingival, or palatinal mucosa of iatrogenic origin can exhibit various clinical features. The management of traumatic injuries is dependent on the severity of the involvement in the periodontal tissues. While, in most cases, the elimination of the offending agent and symptomatic therapy were sufficient, in severe cases, or when the injury resulted in permanent defects, periodontal surgery and regenerative therapy may be necessary. CONCLUSIONS The skill, experience, and up-to-date knowledge of dentists are the main factors to prevent possible iatrogenic traumas. Although "To err is human," careful practice is very important for the principle "Primum non nocere" ("First do no harm").

Abstract
BACKGROUND Ehlers-Danlos syndrome (EDS) is a group of collagen disorders primarily affecting the skin and joints. This case report describes the periodontal management of a case of hypermobile EDS (type III) associated with atypical gingivitis. METHODS A 17-year-old Caucasian female with a history of EDS type III presented with erythematous mucogingival lesions. An incisional biopsy was taken. The treatment objective was to control the mucogingival inflammatory lesions. Plaque control measures were followed with anti-inflammatory medications. Prednisone was administered systemically for 3 weeks (first week: 30 mg/day, second week: 15 mg/day, and third week: 5 mg/day), and was followed with topical applications of clobetasol (0.05%) twice daily for 2 weeks. Persistent marginal gingival inflammation was managed with a 3-month course of doxycycline (20 mg) twice/day. The patient was placed on a 3-month maintenance program and monitored for over a year RESULTS Histopathology showed multiple granulomas enclosing fragments of crystalline foreign material. Steriodal anti-inflammatory medications partially reduced the size and intensity of the mucogingival lesions. Doxycycline controlled the residual marginal inflammation. A 3-month maintenance interval helped in maintaining the results obtained. CONCLUSIONS The collagen disorder may have facilitated the introduction and lodging of foreign material within the gingival tissues, initiating a foreign body reaction. Poor healing associated with EDS excluded surgical excision and necessitated the use of anti-inflammatory medications. A combined approach of plaque control measures along with anti-inflammatory medications was helpful in controlling the mucogingival inflammatory lesions associated with this condition.

Abstract
BACKGROUND The most recent classification of periodontal diseases includes a new section on traumatic gingival lesions. Traumatic lesions of the gingiva are thought to be highly prevalent, yet the periodontal literature contains few references on the topic. The purpose of this article is to present a broad spectrum of traumatic gingival lesions of iatrogenic, accidental, and factitious origin. METHODS Twelve clinical cases were selected to document chemical (due to aspirin, snuff, and peroxide), physical (due to malocclusion, flossing, removable partial denture, oral piercing, and self-inflicted trauma), and thermal (due to overheated ultrasonic scaler, hot food, and ice) injury to the gingiva. RESULTS Chemical, physical, and thermal gingival injuries of iatrogenic, accidental, or factitious origin can have a variety of presentations with overlapping clinical features. Although the appearance and associated symptoms of a gingival lesion may be suggestive of a particular traumatic etiology, useful or confirmatory diagnostic information is often discovered through careful history-taking. The management of gingival injuries typically requires elimination of the insult and symptomatic therapy. If permanent gingival defects resulted from the injury, periodontal plastic surgery may be necessary. CONCLUSIONS A variety of chemical, physical, and thermal injuries may involve the gingiva. Accidental and iatrogenic injuries are often acute and self-limiting, while factitious injuries tend to be more chronic in nature.

Abstract
Part of periodontology involves the diagnosis and treatment of a variety of non-plaque-related diseases of the periodontium. The International Workshop for a Classification of Periodontal Diseases and Conditions noted that the periodontist may be called upon to manage non-plaque-related mucocutaneous disorders either alone, or as part of a treatment team consisting of physicians, dentists or other allied health care professionals. This informational paper will review the etiology, clinical manifestations, diagnosis, and treatment of the most common chronic mucocutaneous diseases, including those that may present as desquamative gingivitis or intraoral vesiculobullous lesions. This paper is intended for the use of periodontists and other members of the dental profession.

Abstract
With the advent of newer pharmacological approaches to the treatment of human immunodeficiency virus (HIV) infection, the incidence and progression of both atypical and conventional periodontal diseases are changing. The incidence of necrotizing periodontitis and gingival diseases of fungal origin appears to be on the decline as a result of these therapies that have led to increased life spans for HIV patients. However, in cases where these therapies lose their effectiveness and HIV patients relapse into an immunosuppressed state, these conditions may recur. Recent evidence has shown that HIV patients with more conventional periodontal diseases such as chronic periodontitis may have increased attachment loss and gingival recession when compared to their HIV-negative counterparts. This pattern of loss of periodontal support may be due in part to a diffuse invasion of opportunistic bacterial infections, viruses, and fungi into the gingival tissue, leading to a more elevated and more diffuse destructive inflammatory response in the periodontal soft and hard tissues. While the accepted approaches to treating the spectrum of periodontal diseases in HIV patients remain essentially unchanged over the past 15 years, the impact of newer systemic therapies on patient immunocompetence may influence treatment decisions.

Abstract
The workshop considered six related questions about periodontal changes seen in HIV infection. 1) To what extent are specific periodontal changes associated with HIV? 2) Are conventional periodontal diseases modified by HIV infection? The changes associated with HIV appear to be modified presentations of conventional diseases. Research should identify initiation and progression factors for necrotizing diseases. 3) What is the role of geography and transmission groups? These questions cannot be answered without greater standardisation of research methods. 4) Has the epidemiology of these changes changed with the advent of new therapies? The data required to answer this question should be available soon but this question is irrelevant to the vast majority of people with HIV. 5) What pathogens are involved in periodontal changes seen in HIV infection? The role of Candida spp. and other potential pathogens requires further investigation. 6) What management protocols are suitable for the periodontal diseases? The significance of periodontal diseases among people with HIV in developing countries is not known. Further research is needed of the effectiveness of interventions especially necrotizing disease in developing countries. The quality of research of these diseases would be enhanced by standardized approaches. A list of relevant variables might prevent their omission from studies.
