Abstract
INTRODUCTION Gingival recession typically develops over a long period of time. Development or progression of gingival recession in a short time and in the absence of acute trauma is exceedingly rare. The aim of this case report is to present a case of severe gingival recession developing in a systemically healthy patient during the last trimester of a routine pregnancy. CASE PRESENTATION A 34-year-old woman, successfully treated 3 years earlier for a localized gingival recession on tooth #24, compliant with home care and maintenance visits, discontinued maintenance during pregnancy. A localized 2-mm deep Miller Class I recession defect on tooth #26 was under follow-up and had been stable during maintenance. The patient presented at 2-months postpartum. She reported that she had noticed localized inflammation and progression of the recession on tooth #26 during the last gestational trimester; she denied any history of trauma. During examination, the recession on tooth #26 had progressed into a 6-mm deep Miller Class II defect. The defect was treated with a connective tissue graft procedure. At 14 months after surgery, the clinical outcome remained satisfactory and stable. CONCLUSIONS Rapid and severe localized gingival recession can occur during routine pregnancy. In light of the evidence indicating safety of routine periodontal care during pregnancy, pregnant females should be encouraged to continue their maintenance periodontal care to minimize the potential of irreversible sequelae from pregnancy-associated gingival inflammation.

Abstract
UNLABELLED Marijuana, prepared from the plant Cannabis sativa, is the most widely used illicit drug in the United States. Marijuana use has been associated with adverse psychosocial and health effects, including effects on oral tissues. Periodontal literature has limited references to the periodontal effects of cannabis use. In this report, we present two cases of marijuana-associated gingival enlargement and review the literature on oral complications of marijuana use. METHODS Two asymptomatic males, aged 23 and 42 years, presented independently for oral prophylaxis. Both had an unremarkable medical history and related a history of significant marijuana use of 2-16 years duration. Common findings following oral and periodontal examination were nicotinic stomatitis-like lesions, uvulitis and gingival enlargement. Marginal and papillary gingiva of the anterior dentition were the areas primarily affected by gingival enlargement, while some of these areas exhibited a nodular or "pebbly" appearance. RESULTS Marijuana-associated gingival enlargement was diagnosed in the reported cases. A review of the literature revealed two other reports of marijuana-associated gingival enlargement, all in young adult males with chronic (2 or more years) cannabis use. These authors reported a resemblance to phenytoin-induced enlargement. Biochemical similarities between phenytoin and cannabis active compounds suggest possible common pathogenetic mechanisms. Uvulitis and nicotinic stomatitis appear to be the two most common of the several oral manifestations of marijuana use. CONCLUSIONS Chronic marijuana use may result in gingival enlargement with clinical characteristics similar to phenytoin-induced enlargement.

Abstract
AIM Periodontitis and caries are two of the most prevalent diseases to affect humans, however; the individual susceptibility to these diseases varies significantly in the population. The aim of this investigation, therefore, was to examine the influence of host genotype on the composition of health-associated supragingival and subgingival microbiomes. MATERIALS AND METHODS Subgingival and supragingival plaque was collected from orally and systemically healthy adult monozygotic and dizygotic twin pairs. Zygosity was determined by multiplexed PCR amplification of 13 short tandem repeats. Terminal restriction fragment length polymorphism was used for bacterial community profiling. The number of species shared by the twin pairs as well as the similarity of the microbial communities between the twins was computed and compared using two-sample t-test RESULTS There was no difference in the number of species shared by the twin pairs as well as the similarity of the microbial communities between the twin dyads. Age was not a modifier of genetic influence on these microbial parameters. There was no difference between monozygotic and dizygotic twin pairs in the correlation between supragingival and subgingival community similarity. CONCLUSION The contributory role of host genotype, if any, is not apparent on an established, health-associated oral microbial community.

Abstract
BACKGROUND The distribution of the attachment of the maxillary labial frenum in the children of different ethnic backgrounds has not been studied extensively. AIM The purpose of this cross-sectional study was to examine the prevalence of the various types of maxillary labial frenum attachment in the children of different ethnic backgrounds. DESIGN Children (aged 1-18) attending a public health clinic in Lavrion, Greece, were clinically examined for maxillary frenum attachment location. Demographic information was recorded. Parents provided written informed consent. RESULTS The examined children were 226, with mean (± standard deviation) age of 8.5 ± 3.0 years. They were of Greek (51%), Albanian (20%), Turkish (12%), and Afghan (11%) descent. The prevalence of the maxillary labial frenum attachment was mucosal (10.2%), gingival (41.6%), papillary (22.1%), and papillary penetrating (26.1%). Frenum attachment differed significantly by age (P = 0.001). The age of children with mucosal- or gingival-type frenum was significantly greater than the age of children with papillary penetrating-type frenum. Frenum attachment did not differ by gender or ethnic background (P ≥ 0.20). CONCLUSIONS The results of this study suggest that, in children, ethnic background and gender are not associated with maxillary labial frenum attachment type, whereas age is strongly associated.

Abstract
BACKGROUND Despite the reported effects of smokeless tobacco (ST) on the periodontium and high prevalence of ST use in rural populations and in men, studies on this specific topic are limited. The purpose of this cross-sectional investigation is to evaluate the periodontal health status of male ST users from a rural population. METHODS Adult male residents of two rural Appalachian Ohio counties and daily ST users, with a unilateral mandibular oral ST keratosis lesion, were recruited. Subjects completed a questionnaire and received oral examination. Teeth present, ST keratosis lesion, plaque and gingival index, probing depth (PD), recession depth (RD), and attachment level were recorded. Statistical analysis compared ST-site mandibular teeth (teeth adjacent to the subject's unilateral ST keratosis lesion) to NST-site teeth (contralateral corresponding teeth). RESULTS This study includes 73 ST users. Recession prevalence is much greater in ST-site quadrants (36%) compared to NST-site quadrants (18%; P <0.001). Twice as many teeth had recession on ST-site (approximately 20%) than NST-site (approximately 10%; P = 0.0001). Average buccal RD on ST-site teeth did not differ from that on the NST-site teeth (P = 0.0875). Although average buccal attachment loss is greater on ST-site teeth (P = 0.016), the mean difference is <0.5 mm. When stratified by years of ST use, subjects using ST for 10 to 18 years exhibit the most differences between ST and NST sites, whereas subjects using ST for <10 years show no differences. CONCLUSION The results indicate that greater gingival recession prevalence and extent are associated with ST placement site in rural male ST users.

Abstract
BACKGROUND This prospective clinical study aims to evaluate the influence of cigarette smoking on free gingival graft (FGG) healing, by assessing FGG dimensional changes and donor-site wound healing. METHODS Twelve non-smokers and 10 smokers treatment planned for FGG to augment keratinized tissue dimensions in the mandibular incisor area completed the study. All subjects received standardized FGG of same dimensions. Probing depth, gingival margin position, clinical attachment level, keratinized tissue (KT) width, gingival thickness, and FGG dimensions (width, length, and area) were assessed and recorded before surgery, and 7, 15, 30, 60, and 90 days postoperatively. The palatal donor area was evaluated for immediate bleeding and complete wound epithelialization. Differences between the two groups (smokers and non-smokers) were statistically analyzed. RESULTS FGG dimensions changed significantly postoperatively. At 90 days postoperatively, FGG width, length, and area were respectively reduced by 31%, 22%, and 44% in non-smokers and by 44%, 25%, and 58% in smokers (no significant differences between groups; P >0.05). Significant KT increases were observed in both non-smokers and smokers (5.4 and 4.8 mm, respectively). Donor-site immediate bleeding was significantly more prevalent in non-smokers (75%) compared to smokers (30%) (P = 0.04). At 15 days postoperatively, donor-site complete epithelialization was much more prevalent in non-smokers (92%) than in smokers (20%) (P <0.002). CONCLUSION Smoking alters FGG donor-site wound healing by reducing immediate bleeding incidence and by delaying epithelialization, although it does not have discernible effects on postoperative FGG dimensional changes.

Abstract
BACKGROUND The buccal bifurcation cyst (BBC) is a paradental cyst that typically presents on the buccal aspect of mandibular permanent first molars in children 6 to 11 years of age. Histopathologic features are non-specific and closely resemble other inflammatory odontogenic cysts. The aim of this article is to report a case of a BBC and to review the management of such lesions. METHODS A 7-year-old white male, complaining of lower right tooth pain and swelling, presented to the Nationwide Children's Hospital Dental Clinic. A clinical examination revealed no caries and swelling localized to the area approximating tooth #30 with a 15-mm probing depth on the buccal aspect. Radiographs revealed a radiolucency involving the bifurcation and root area of tooth #30, accompanied by the distal displacement of unerupted tooth #31. Therapy consisted of a simple surgical enucleation of the cyst. RESULTS A microscopic evaluation revealed a chronically inflamed cyst lined by a non-keratinized stratified squamous epithelium. The immediate postoperative course was uneventful. At 14 months postoperatively, the development of teeth #30 and #31 was noted as normal. Probing depths around tooth #30 were <or=4 mm, tooth #31 was no longer displaced, and no recurrence was detected. CONCLUSION The simple surgical enucleation of the BBC provided good short- and long-term outcomes without compromising the development of associated molars.

Abstract
BACKGROUND Evidence suggests an association between periodontal disease and coronary heart disease (CHD). C-reactive protein (CRP), fibrinogen, and white blood cell (WBC) counts are markers of inflammation, and their systemic levels have been associated with CHD risk. This pilot study investigated the effect of non-surgical periodontal therapy on systemic levels of CRP, fibrinogen, and WBC counts in subjects with CHD or no CHD (NCHD). METHODS Twenty-seven angiographically defined patients with CHD and 18 subjects with NCHD aged >or=40 years were recruited for the study. Periodontal disease was measured through the clinical parameters bleeding on probing (BOP) and probing depth (PD). All subjects received non-surgical periodontal therapy that included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers (CRP, fibrinogen, and WBC counts) were measured prior to and 1 month after periodontal therapy. RESULTS Seventeen subjects with CHD and 11 subjects with NCHD completed the study. Subjects with CHD or NCHD experienced significant reductions in BOP (59% and 34%, respectively; P <0.05) and PD (41% and 35%, respectively; P <0.05), with non-significant intergroup differences (P >0.05). In all subjects, CRP, fibrinogen, and WBC counts were reduced significantly (21% to 40%) after periodontal therapy (P <0.05). CONCLUSIONS Periodontal treatment resulted in significant decreases in BOP and PD and lowered serum inflammatory markers in patients with CHD or NCHD. This may result in a decreased risk for CHD in the treated patients. These findings will allow pursuit of a large-scale randomized intervention trial in this population.

Abstract
BACKGROUND The gingival cyst of the adult (GCA) is an uncommon developmental cyst of odontogenic origin most frequently seen near mandibular canines and premolars and is routinely treated with excisional biopsy. This article presents a case of a GCA treated with a combined regenerative approach and reviews the GCA literature with an emphasis on the clinical aspects of this lesion. METHODS A 54 year-old man presented for treatment of generalized severe chronic periodontitis. Clinical examination revealed a cystic lesion in the gingiva of the mandibular canine-premolar area. Radiographs revealed a well-defined radiolucency in the coronal one-third of the tooth roots. Surgical enucleation of the lesion revealed root exposure of the second premolar. Because of the anatomy of the lesion-associated defect, regenerative treatment, using a combination of freeze-dried bone allograft and a collagen membrane, was considered the therapeutic approach of choice. RESULTS The biopsy revealed histologic features consistent with a GCA. Clinical and radiographic examinations 1 year post-surgery indicated uneventful soft tissue healing and bone fill of the initial defect. The review of the literature revealed only one other case of root exposure associated with GCA and no previous report of regenerative therapy. CONCLUSIONS In rare instances, a GCA lesion may result in tooth-root exposure. In such cases, a combined regenerative treatment approach may be used to achieve resolution.

Abstract
Abstract
Success rates for both periodontal and implant therapy are often dependent on site and tooth type. For periodontally involved mandibular molars, the decision to hemisect or to extract and place an implant is often complicated. The purpose of the present study was to evaluate the outcomes of the aforementioned treatment modalities for mandibular molars in a private practice setting. A retrospective chart review was performed. In one group of patients (n = 32), 56 mandibular first or first and second molars were treated by hemisection (Group H). A second group (n = 28) received 36 implants in the mandible to replace periodontally involved first or first and second molars (Group I). All patients had been in maintenance for at least 4 years after treatment. The occurrence and timing of posttreatment complications were evaluated. Data were analyzed by parametric and nonparametric statistics, as indicated. The majority of hemisected teeth (68% of Group H) and implants (89% of Group I) remained free of complications for the entire observation period. Group H had a greater incidence of overall complications (P = .027) and nonsalvageable complications (P = .013) than Group I. For both groups, the percent CAL loss per year was greater for the teeth/implants that experienced complications than in the those that remained complication free (p<0.015). Within the limitations of this study, the results indicated that, in periodontitis patients, hemisected mandibular molars were more prone to complications than implants.

Abstract
BACKGROUND Tissue-engineered bone grafts represent an appealing alternative for maxillary sinus augmentation because they eliminate the significant drawbacks associated with extra- and intraoral bone-harvesting procedures. In the present case series, we document the outcomes of sinus augmentation surgery using tissue-engineered bone grafts. METHODS Three patients requiring bilateral sinus augmentation received tissue-engineered bone grafts combined with xenograft prior to implant placement. Implants were placed and loaded 6 and 12 months postaugmentation, respectively. Radiographs were taken and clinical examinations were performed preoperatively and at 4, 6, 12, and 18 months postaugmentation. Biopsies were obtained at 4 and 6 months postaugmentation. Standardized orthopantomograms were used to measure the posterior maxilla bone height. RESULTS None of the patients experienced untoward complications during or following the therapeutic procedures. Ten implants were inserted into the augmented sinuses and loaded. Biopsies revealed a lack of inflammation or pathology; newly formed fibrous bone with osteoblastic activity and xenograft particles was evident. Compared to 4 months postaugmentation, augmented tissue was more mature at 6 months. The postoperative (18 months) bone height in augmented areas was significantly greater than the preoperative height (P <0.0001), representing an approximately 4.5-fold increase in bone height. CONCLUSIONS Sinus augmentation using tissue-engineered bone grafts was successful in all three cases, permitting the subsequent insertion and loading of dental implants. The present cases demonstrated the feasibility of using engineered bone for sinus augmentation. Controlled clinical trials will be required to evaluate this new and evolving treatment modality.

Abstract
BACKGROUND Despite the potential significance of early soft tissue healing to long-term outcomes, this aspect of one-stage dental implants has not been investigated. The purpose of this prospective study was to characterize clinical and microbiologic parameters of early soft tissue healing around dental implants placed following a one-stage protocol. METHODS Twenty-one patients (11 females and 10 males, aged 18 to 78 years; two smokers) needing a single implant were included. Clinical parameters included probing depth, buccal flap thickness, papilla height, and bleeding on probing. Subgingival plaque samples were obtained pre- and postoperatively and analyzed using molecular techniques. RESULTS The newly formed peri-implant sulcus probing depth remained fairly stable from 4 to 12 weeks (P > 0.05). There was no statistically significant association between flap thickness or papillary height and number of implant bleeding sites at 12 weeks (P > 0.05). Detection of known periodontal pathogens was rare. Fusobacterium nucleatum was present in 17 patients prior to surgery, and 71% of them became carriers of this bacterium at the implant site by the second postoperative week. The number of F. nucleatum-positive subjects around the implant was significantly lower than the number of F. nucleatum-positive subjects around teeth (P < 0.05). CONCLUSIONS Peri-implant soft tissue clinical maturity may be established as early as 4 weeks following implant placement by a one-stage surgical protocol; neither preexisting flap thickness nor papillary height seemed to influence newly forming peri-implant sulcus depth or bleeding on probing prevalence. For the most part, the newly created peri-implant crevices were colonized by specific bacteria within 2 weeks.

Abstract
BACKGROUND Smoking adversely affects the short-term outcomes of coronally positioned flap (CPF) root coverage procedures, but the long-term stability of this procedure in smokers has not been studied. The objective of this study was to evaluate the effect of smoking on the long-term outcomes of CPF in recession treatment. METHODS CPF was used to treat a Miller Class I defect in a maxillary canine or premolar in 10 current smokers (> or =10 cigarettes daily for > or =5 years) and 10 non-smokers (never smokers). At baseline and 6, 12, and 24 months, clinical parameters, including probing depth (PD), clinical attachment level (CAL), recession depth (RD), and width of keratinized tissue (KT), were determined. RESULTS Intragroup analysis showed that CPF failed to maintain the gingival margin at the initially achieved position. RD significantly increased in smokers (from 0.84 +/- 0.49 to 1.28 +/- 0.58 mm) and in non-smokers (from 0.22 +/- 0.29 to 0.50 +/- 0.41 mm) between 6 and 24 months. Further analysis showed that 50% of smokers and 10% of non-smokers lost between 0.5 and 1.0 mm of root coverage in the same period. Intergroup analysis showed that smokers had significantly greater residual recession (P = 0.001) at 24 months. Both smokers and non-smokers lost CAL and experienced decreases in KT. CONCLUSIONS The long-term stability of CPF outcomes is less than desirable, particularly in smokers. Two years after a CPF procedure, smokers have significantly greater residual recession compared to non-smokers both statistically and clinically.

Abstract
BACKGROUND Despite the common occurrence of localized gingival enlargements, which often represent reactive lesions, the temporal and spatial association of such a lesion with a central jaw lesion has not been reported. The purpose of this case report is to present the exceptional combination of a peripheral ossifying fibroma and a central odontogenic fibroma. The differential diagnosis and management of each lesion is reviewed. METHODS A 45-year-old black female presented with a chief complaint of a painless protuberance in the left mandible of 1-year duration. Clinical and radiographic examination revealed a gingival enlargement localized between teeth #21 and #23 and a multilocular radiolucent lesion with radiopaque foci in the same area. Excisional biopsy of the gingival lesion and incisional biopsy of the central lesion were performed, and specimens were submitted for histopathological analysis. RESULTS Biopsy of the gingival lesion revealed stratified squamous epithelium and highly cellular fibroblastic component presenting central areas of calcification, features consistent with a diagnosis of peripheral ossifying fibroma. The central lesion was characterized by cellular fibrous tissue admixed with rests of odontogenic epithelium and few calcification areas, features consistent with a diagnosis of central odontogenic fibroma/World Health Organization type. Subsequently, the central lesion was enucleated. After 1-year follow-up, no recurrence has been observed. CONCLUSIONS The combination of a rare central lesion with a common gingival lesion may present unique diagnostic and therapeutic challenges. Clinician awareness regarding the possibility of such a combined presentation and its implications will help to ensure optimal treatment outcomes.

BACKGROUND Paracoccidioidomycosis, a deep mycosis endemic in parts of Latin America, often presents with oral lesions involving the gingiva. Nevertheless, the periodontal literature is devoid of references to oral paracoccidioidomycosis. The purpose of this study was to characterize the gingival involvement in oral paracoccidioidomycosis and to contrast clinical and histopathologic diagnosis of the disease. Differential diagnosis and management of oral paracoccidioidomycosis were reviewed. METHODS From January 1995 to October 2006, the files of the Oral Pathology Laboratory, School of Dentistry, Alfenas Federal University, were reviewed to identify cases referred because of a clinical diagnosis of oral paracoccidioidomycosis. Data collected included patient demographics (age, gender, race, and occupation), clinical information (oral lesion location), and histopathologic diagnosis. RESULTS Forty-six cases were identified, and 34 were histopathologically confirmed as paracoccidioidomycosis. Of the remaining 12 cases, one-half were diagnosed as either carcinoma or dysplastic leukoplakia. Of the 34 confirmed paracoccidioidomycosis cases, 45% presented with multiple site involvement, whereas the gingiva/alveolar process was the most prevalent site overall (52%). The gingiva/alveolar process was the most prevalent site in both multiple and single site cases. The majority of patients were men (88%), white (75%), and in their fourth decade of life (47%). Statistical analysis revealed that patients with gingival/alveolar process involvement were demographically indistinguishable from those without. CONCLUSIONS Oral paracoccidioidomycosis has a strong predilection for the gingiva, whereas patients with gingival lesions do not differ from patients lacking such involvement. Early diagnosis of gingival/oral lesions may prevent life-threatening complications of this mycosis.

Abstract
The use of dental implants to support mandibular or maxillary overdentures is a widely used treatment modality. Advantages are an increase in retention, an increase in chewing ability, and easy access for oral hygiene procedures. While telescopic and conical crowns have been used for decades to connect natural teeth to overdentures, not many cases have been reported in the literature of telescopic crowns placed on implants to support overdentures. This article describes 7 patients with overdentures supported by telescopic crowns who received 65 implants (ITI Straumann). The cases presented in this report have been in function for up to 4.5 years. During that time no adverse events were reported. The use of telescopic crowns as attachments for implant-supported overdentures may be a viable treatment option.

Abstract
BACKGROUND Verruciform xanthoma (VX) is a benign lesion that primarily affects the oral cavity, most frequently the gingiva. VX lesions are characterized by xanthoma cells (lipid-laden macrophages or foam cells) found in the superficial connective tissue. To characterize these foam cells further, immunohistochemical techniques were used to investigate the presence of macrophage subpopulations in oral lesions of VX. METHODS Sixteen biopsy samples of VX lesions from the oral cavity (six from gingiva, three from palate, and seven from other mucosa) were studied. Immunohistochemical analysis was performed using antibody probes to macrophage subpopulations, including RM3/1 (reparative), 25F9 (resident), and 27E10 (inflammatory). The percentage of antibody-labeled foam cells was determined by visual counts of selected fields within lesional connective tissue. RESULTS The proportion of VX lesions that demonstrated positive xanthoma cell reactivity with antibodies RM3/1, 25F9, and 27E10 was 100%, 88%, and 50%, respectively. Foam cells that stained positively with RM3/1, 25F9, and 27E10 represented 61.5% +/- 19.6%, 51.8% +/- 29.4%, and 10.9% +/- 14.7% of the counted cells, respectively. When results were analyzed based on anatomic location (gingiva, palate, and other mucosa), there was no difference in the percentage of positively stained cells by anatomic site for any of the three antibodies (P >0.05). Similarly, there were no differences between masticatory (gingiva and palate) and other mucosa (P >0.05). CONCLUSIONS VX lesions contain primarily reparative and resident foam cells, with limited numbers of inflammatory macrophages, consistent with a chronic reactive process. These findings were independent of the anatomic site.

Abstract
Clonidine has recently been used as a pre-operative medication and sedative/anxiolytic drug. Its extended duration of action makes it suitable for longer procedures. In this randomized, crossover, placebo-controlled clinical trial, we characterized the effects of oral clonidine pre-treatment on intravenous diazepam/meperidine sedation using the bi-spectral index (BIS) in 13 participants. Clonidine significantly increased the numbers of BIS-depressed readings and percent memory loss during sedation, while reducing total diazepam and post-operative analgesic dosages by 44% and 55%, respectively. Systolic, diastolic, and mean arterial blood pressures, as well as pulse rates, were reduced. Respiratory rate, oxygen saturation, end-tidal CO(2), and recovery from sedation were unchanged. Participants, surgeons, and sedationists preferred clonidine over the placebo. Clonidine pre-treatment increased and prolonged sedation and amnesia and stabilized vital signs while significantly decreasing diazepam and post-operative analgesic usage. These results suggest that pre-operative clonidine administration could be a useful supplement to intravenous sedation for dental procedures of long duration.

Abstract
BACKGROUND Gingival pigmentation is a common finding, may be of endogenous or exogenous origin, and can have diagnostic significance. Diffuse gingival pigmentation may be physiologic in nature or can be due to environmental factors, drugs, endocrine disorders, or genetic conditions. We present four cases of diffuse gingival pigmentation due to traditional gingival tattooing and review the literature on this practice. METHODS Four black females (aged 19 to 56 years) of West African origin (Mauritania and Senegal), representing three different ethnic groups (Fulani, Mandinka, and Soninke) presented with various chief complaints. All exhibited diffuse pigmentation of the maxillary vestibular gingiva extending to the second premolar areas, without any associated radiographic abnormalities. The color ranged from intense blue gray to light gray or grayish pink. One case was biopsied for histopathologic evaluation. RESULTS Questioning revealed that the women had had one or more sessions of traditional gingival tattooing. In one case, the procedure was performed in a dental office. The color range appeared to depend on the time that elapsed since the last procedure. The biopsy exhibited dense fibrous connective tissue containing aggregates of foreign material consistent with a foreign body tattoo. CONCLUSIONS Gingival tattooing, a cultural practice prevalent in certain African ethnic groups, results in diffuse pigmentation. Outside of Africa, it may be misinterpreted as racial pigmentation or pose a diagnostic puzzle. The color and distribution pattern of diffuse gingival pigmentation often are quite suggestive, and the clinical diagnosis should be confirmed by patient history. In selected cases, biopsy may be necessary to exclude other diagnostic considerations.

Abstract
OBJECTIVES The purpose of this study was to assess whether identification of subjects with different susceptibility to plaque-induced gingival inflammation is dependent on the length of time of de novo plaque accumulation. METHODS Retrospective analysis of data obtained from a recently reported randomized split-mouth localized experimental gingivitis trial involving 96 healthy non-smokers. Gingival and plaque index, gingival crevicular fluid volume (GCF), angulated bleeding score, and the derived parameter cumulative plaque exposure (CPE) were recorded at days 0, 7, 14, and 21. The primary outcome variable to express severity of inflammation was GCF and each subject was a statistical unit. Based on subject distribution of GCF-day 21 residuals after standardization for CPE-day 21, two sub-populations (upper and lower distribution quartiles) were selected. They were, respectively, defined as "high responders" (HR) (n=24) and "low responders" (LR) (n=24) and characterized by significantly different severity of gingivitis to similar amounts of plaque deposits. The same analysis was repeated at days 7 and 14. Prevalence of HR and LR was compared between days using the chi(2) [ML] test. RESULTS For both day 7 and day 14, the quartile distribution of LR and HR was statistically significant (p=0.02). Fifty percent of LR and 71% of HR presented a consistent level of susceptibility to plaque-induced gingival inflammation even after only 7 and/or 14 days of plaque accumulation. CONCLUSIONS These findings support the concept that the subject-based susceptibility to plaque-induced gingival inflammation is an individual trait, only partly related to the length of time of exposure to plaque.
