Self-reported oral hygiene habits among dental patients in Italy.

OBJECTIVE: The objective of this survey was to assess oral hygiene habits and compliance with guidelines for good oral health set forth by the Italian Ministry of Health (IMH). SUBJECTS AND METHODS: A sample of 2,200 self-administered questionnaires was sent to four dental clinics across Italy to assess sociodemographic information, oral hygiene habits, frequency of dental visits and services received at previous visits among a population of adult patients. RESULTS: Of the 2,200 questionnaires, 1,201 (54.6%) were returned. Findings showed that full compliance with the IMH recommendations was low (12%): a small number of patients (n = 223, 18.6%) visited a dentist every 6 months and only 256 (23.5%) brushed their teeth at least twice a day. CONCLUSION: Our data showed that regular attendance (at least 1 visit/year) at dental clinics for routine check-up and brushing teeth at least twice a day were poor. Therefore, we recommend that clinicians educate and motivate their patients about the benefits of healthy oral hygiene practices.

Correlation between Bruxism and Gastroesophageal Reflux Disorder and Their Effects on Tooth Wear. A Systematic Review.

Bruxism and gastroesophageal reflux (GERD) can lead to wear of the dental tissues. Wear has a mechanical or chemical origin, and it is of extrinsic or intrinsic type. Bruxism and GERD are two etiological factors of dental wear. The intrinsic mechanical wear (abfraction) of Bruxism and intrinsic chemical wear (erosion) of GERD are both involved in sleep disorders; indeed, they could have associations and act in synergy in dental wear. The purpose of this review was to find out the possible associations between bruxism and GERD and their effects on tooth wear. The research was conducted on PubMed and the Cochrane Library using the following Keywords/Mesh Terms: Tooth wear, Bruxism, Sleep Bruxism, Sleep Disorders, or GERD. Only systematic reviews and clinical studies performed exclusively on human subjects were included in the review. Initially, the research gave more than 630 results on dental wear, bruxism and GERD and after application of the inclusion criteria irrelevant studies were excluded, and 5 studies were finally included in this review. It was possible to observe the presence of some associations between the two problems (reflux and GERD) and hypothesize negative effects on tooth wear. This research revealed the presence of an interconnection between these three problems (reflux, GERD and tooth wear) that can further act in synergy by attacking the hard dental tissues both from a chemical (reflux) and mechanical (bruxism) point of view. The dentist could play a role of "sentinel" in a multidisciplinary team, intercepting these problems early in order to treat them in the most appropriate way.

Epigenetic Profiling in the Saliva of Obese Pregnant Women.

Maternal obesity is associated with inflammation and oxidative stress, strongly impacting the intrauterine environment with detrimental consequences for both mother and offspring. The saliva is a non-invasive biofluid reflecting both local and systemic health status. This observational study aimed to profile the epigenetic signature in the saliva of Obese (OB) and Normal-Weight (NW) pregnant women. Sixteen NW and sixteen OB Caucasian women with singleton spontaneous pregnancies were enrolled. microRNAs were quantified by the OpenArray Platform. The promoter region methylation of Suppressor of Cytokine Signaling 3 (SOCS3) and Transforming Growth Factor Beta 1 (TGF-Beta1) was assessed by pyrosequencing. There were 754 microRNAs evaluated: 20 microRNAs resulted in being differentially expressed between OB and NW. microRNA pathway enrichment analysis showed a significant association with the TGF-Beta signaling pathway (miTALOS) and with fatty acids biosynthesis/metabolism, lysine degradation, and ECM-receptor interaction pathways (DIANA-miRPath). Both SOCS3 and TGF-Beta1 were significantly down-methylated in OB vs. NW. These results help to clarify impaired mechanisms involved in obesity and pave the way for the understanding of specific damaged pathways. The characterization of the epigenetic profile in saliva of pregnant women can represent a promising tool for the identification of obesity-related altered mechanisms and of possible biomarkers for early diagnosis and treatment of pregnancy-adverse conditions.

Self-reported oral hygiene habits and periodontal symptoms among postpartum women.

PURPOSE: The purpose of this study is to describe oral hygiene practices and periodontal symptoms among postpartum women and to assess whether self-reported periodontal symptoms are correlated with a clinical diagnosis of periodontal disease. METHODS: A self-administered questionnaire was developed to assess socio-demographic information, oral hygiene habits and frequency of dental visits among a group of 409 postpartum women. Additional questions included information on self-reported periodontal symptoms. Pregnancy information was obtained from medical charts. RESULTS: 99.3% of the participants brushed their teeth every day; 46.2 and 53.8% reported teeth brushing once a day or more, respectively. Periodontal disease was present in 61.4% of women. Patients with gum swelling and tooth mobility were almost twice as likely to have a periodontal disease (OR 1.7, CI 95% 0.9-2.8 and OR 1.7, CI 95%: 0.8-3.5, respectively). No associations were found between periodontal disease, gum swelling PTB and/or LBW. CONCLUSIONS: Maternal clinical periodontal disease at delivery was related with self-perceived gum swelling and tooth mobility. Dentists and prenatal medical care providers may have the opportunity to target pregnant women that might be at higher risk for periodontal disease by asking whether they have tooth mobility and/or swollen gums.

Oral cancer knowledge: a survey administered to patients in dental departments at large Italian hospitals.

We assessed the oral cancer (OC) knowledge, including risk factors and clinical symptoms, among patients attending dental departments within Italian university hospitals. Two thousand and two hundred questionnaires were sent to four hospitals in order to assess patients' knowledge regarding clinical and epidemiological aspects of OC; OC knowledge was evaluated overall and stratified by oral cancer family history. Participants frequently identified cigarette smoking (87.8%) and heavy alcohol consumption (58.6%) as a risk factor for oral cancer, knew the clinical signs of OC (65-79% depending on the specific symptom) and reported that early detection was related to better prognosis of oral cancer (94%). Individuals with a positive family history for oral cancer were significantly more likely to identify risk factors for oral cancer correctly yet family history of OC did not affect smoking status. Less than 15% of patients reported having received OC counseling by a dentist or physician.

Mucosal Melanoma of the Hard Palate: Surgical Treatment and Reconstruction.

Mucosal melanomas of the head and neck region are uncommon pathologies that can affect the oral cavity, and are characterized by a high rate of mortality. Considering the lack of knowledge regarding risk and prognostic factors, current best clinical practice is represented by a large surgical excision with disease-free margins, eventually associated with a reconstructive flap. Indeed, given the frequent necessity of postoperative radiotherapy and fast healing process, a reconstruction of the surgical gap is advisable. Even if several flaps have been most commonly used, the submental island flap represents a valid alternative thanks to local advantages and similar oncologic outcomes compared to free flaps.

Solitary Extramedullary Plasmacytoma Presenting as Asymptomatic Palatal Erythroplakia: Report of a Case.

Solitary plasmacytoma (SP) is a rare malignant tumor of plasma cells with no systemic spread; however, when it disseminates and affects multiple skeletal sites, it is called multiple myeloma (MM). The etiology of solitary plasmacytoma is unknown, with two possible subtypes: solitary extramedullary plasmacytoma (EMP) and solitary bone plasmacytoma (SBP). We present a case of EMP arising as asymptomatic erythroplakia of the palate, which is rarely described in the literature. The definitive diagnosis was obtained with immunohistochemical studies, after which the lesion was subjected to excisional biopsy. At present, after two years of close follow-up, the patient has shown no signs of relapse or conversion to MM. The uniqueness of the case highlights the possibility of an atypical EMP lesion in the head and neck, thus posing a diagnostic and therapeutic challenge for physicians.

General Health, Systemic Diseases and Oral Status in Adult Patients with Coeliac Disease.

The prevalence of coeliac disease in the general population is 0.5%-1%; however, most patients remain undiagnosed until adult age. In some cases, the onset is represented by sub-clinical signs, some of which can be found in the mouth. The aim of this research was to identify any associations between the clinical characteristics of coeliac disease and oral manifestations. A structured questionnaire was administered to a group of 237 individuals with coeliac disease. 100% of the subjects fully completed the questionnaire. Among them, 182 (76.7%) were female, 64 patients (27%) were aged 15 to 24 years, 159 (67%) were aged 25 to 55 and 14 (6%) were aged 56 and over. Significant associations were observed in caries prevalence and dentin sensitivity; in addition, an inappropriate diet was related to oral manifestations; following a gluten-free diet could be important to control the gingival bleeding levels and to manage oral symptoms associated to coeliac disease. In general, the presence of inflammatory symptoms in the mouth seems to be associated with general symptoms of inflammation related to coeliac disease.

Time sequence of bone healing around two implant systems in minipigs: preliminary histologic results.

The aim of this study was to evaluate the early phases of bone healing around two different implant surfaces. For this purpose, four minipigs were used. Implants with rough titanium surfaces (ITI sandblasted/acid-etched and Branemark TiUnite) were placed in the maxillae of the animals and sacrifice was scheduled in such a way that healing times of 3 days, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, and 7 weeks were obtained. Histologic analysis revealed that a similar pattern was observed in the phases of bone healing around both types of implants between 3 days and 7 weeks. This pattern consisted of the replacement of blood clot and bone debris with a provisional connective tissue in the first few weeks and with mineralized tissue and marrow spaces later on. Both rough surfaces allowed for "contact osteogenesis" to take place. (Int J Periodontics Restorative Dent 2009;29:549-555.).

Oral mucosal complications in orthodontic treatment.

BACKGROUND: Orthodontic therapy is used to solve numerous oral problems, but the use of fixed oral devices can also impact negatively the oral cavity, if the treatment is not steadily under control. The aim of this study is to evaluate tooth, bone and soft tissues lesions due to the presence of fixed orthodontic appliances. METHODS: One hundred patients with fixed orthodontic appliances were included in the study. In particular, 20 patients with rapid palatal expander (RPE), 20 patients with Forsus appliance, 20 patients with a fixed multibracket appliance treatment, 20 patients with just the lower vestibular multibracket treatment and 20 patients with both upper and lower vestibular multibracket treatment. An accurate oral examination of the oral cavity, comprehending teeth, bone and soft tissues, was carried out thoroughly, in order to find possible lesions caused by the fixed orthodontic treatment. RESULTS: Concerning RPE, 35% patients had reversible palatal lesions, while 45% patients had the impression of the appliance on the tongue. Periodontal damages were observed in 5% of the patients, as well as tooth lesions (i.e. dental caries). 20% of the patients with Forsus appliance experienced the lesion on the cheek mucosa, while 10% individuals reported periodontal problems, and 15% of the subject suffered for WSL (white spot lesion) and dental caries. Upper vestibular multibracket appliance caused superior labial lesions (15%), cheek mucosal lesions (20%), gingivitis (55%), white spot lesions (WSL) of superior teeth (15%), while dental recessions and periodontitis due to the appliance were rarely observed (5%). Lower vestibular multibracket appliance was frequently the cause of inferior labial lesions (15%), cheek mucosal lesions (15%), gingivitis (50%), WSL of inferior teeth (20%) and also in lower arch dental recessions and periodontitis due to the appliance were rarely observed (5%). Patients with both superior and inferior multibracket appliance experienced upper and/or lower lip lesions (25%), lesions of cheek mucosa (25%), gingivitis (65%) and WSL (30%), and just in few cases periodontitis (10%). Data shows a more critical oral situation in patients with both superior and inferior appliances than people with one-arch therapy. CONCLUSIONS: Orthodontic therapy offers a considerable number of advantages, but it is important to underline what may be the adverse consequences also. This allows the orthodontist to inform the patient of all the possible effects of their therapeutic choice. In most cases, RPE can cause an impression of the device on the tongue and reversible lesions of the palate. On the other hand, the orthodontic fixed therapy can cause gingivitis, followed by mucosal lesions, labial lesions and WSL. For these reasons, an accurate assessment of the patients before the application of fixed orthodontic treatment is necessary. Oral hygiene instructions and motivation are very important, as well as periodic controls of the fixed oral device.

Oral implants placed in bone defects treated with Bio-Oss, Ostim-Paste or PerioGlas: an experimental study in the rabbit tibiae.

OBJECTIVES: To compare the histological features of bone filled with Bio-Oss, Ostim-Paste or PerioGlas placed in defects in the rabbit tibiae by evaluating bone tissue composition and the integration of titanium implants placed in the grafted bone. MATERIAL AND METHODS: Two cylindrical bone defects, about 4 mm in diameter and 6 mm in depth, were created in the tibiae of 10 rabbits. The defects were filled with either Bio-Oss, PerioGlas, Ostim-Paste or left untreated, and covered with a collagen membrane. Six weeks later, one titanium sandblasted and acid-etched (SLA) implant was inserted at the centre of each previously created defect. The animals were sacrificed after 6 weeks of healing. RESULTS: Implants placed in bone previously grafted with Bio-Oss, PerioGlas or Ostim-Paste obtained a larger extent of osseointegration, although not statistically significant, than implants placed in non-grafted bone. The three grafting materials seemed to perform in a similar way concerning their contribution towards implant osseointegration. All grafting materials appeared to be osteoconductive, thus leading to the formation of bridges of mineralized bone extending from the cortical plate towards the implants surface through the graft scaffold. CONCLUSIONS: Grafting with the above-mentioned biomaterials did not add any advantage to the osseointegration of titanium SLA implants in a self-contained defect.

Inflammatory and Oxidative Responses in Pregnancies With Obesity and Periodontal Disease.

BACKGROUND: Maternal obesity is related to immunologic and inflammatory systemic modifications that may worsen the pregnancy inflammatory status. Hormonal changes during pregnancy can adversely affect oral biofilms and oral health initiating or worsening periodontal diseases, with enhanced local and systemic oxidative stress and inflammation. OBJECTIVE: The aim of this study was to examine the relationship between local salivary and systemic parameters of oxidative stress and inflammation in relation to obesity and periodontal diseases. STUDY DESIGN: Sixty-two women with singleton pregnancies were enrolled. Twenty-seven women were normal weight (NW; 18.5< body mass index [BMI] <25 kg/m2) and 35 obese (BMI ≥30 kg/m2). Seventeen of the obese had gestational diabetes mellitus (GDM). During third trimester, periodontal status was evaluated, saliva (s) was collected to assess total antioxidant capacity (s-TAC) and C-reactive protein (s-CRP) levels, and venous plasma (p) was used to measure CRP levels (p-CRP). Maternal, fetal, and placental data were registered at delivery. RESULTS: Levels of s-TAC, s-CRP, and p-CRP were significantly higher in obese, particularly in the presence of GDM, compared to NW and related to each other ( P = .000; r > 0.59), to maternal BMI ( P = .000; r > 0.52), and fasting glycemia ( P < .002; r > 0.47). Periodontal disease was more frequent in obese groups (80%) versus NW (52%; P = .04), particularly when GDM was diagnosed ( P = .009). A significant interaction effect between maternal BMI and oral condition was found for s-TAC levels. Obese with periodontitis showed significant increase in local and systemic parameters versus NW. CONCLUSION: Obesity and periodontal disease could synergistically amplify the inflammatory and oxidative status, resulting in increased local and systemic biomarkers particularly when GDM is diagnosed.

Changing trend of caries from 1989 to 2004 among 12-year old Sardinian children.

BACKGROUND: During the past decades, the prevalence of caries disease in the population of Western industrialized countries has decreased markedly. In children also, a reduction of dental caries experience has been reported by many authors. The aim of this paper was to evaluate the trend of dental caries prevalence in 12-year-old children living in the city of Sassari, (Italy), by five cross-sectional studies conducted in 1989, 1992, 1995, 1998 and 2004. METHODS: In all cohorts, dental caries (DMFT and SiC Index according to WHO indications), was measured. For each variable measured (DMFT and sub-indices, SiC Index), differences in proportions among the five cohorts during the fifteen years were tested using chi2-square test. RESULTS: The mean DMFT index decreased from 4.3 +/- 3.1 in 1989 to 0.8 +/- 1.5 in 2004. The prevalence of untreated caries (DT) had a notable decrease between 1992 and 1995, increased slightly between 1995 and 1998 and had the greatest decrease in 2004. The number of filled teeth remains low. The percentage of caries-free children increased from 10% to 64%, whereas the percentage of untreated caries changed from 44% in 1989 to 62% in 2004. SiC Index decreased from 7.8 in 1989 to 3.9 in 2004. CONCLUSION: On the basis of the results of DMFT and SiC Index, caries experience has been reduced. The vigilance and the promotion of a higher standard of personal oral hygiene and dental check-ups are necessary to obtain an improvement of oral status in the future adult population and to reach the new WHO global goals.

Diagnosis and management of xerostomia and hyposalivation.

Xerostomia, the subjective complaint of dry mouth, and hyposalivation remain a significant burden for many individuals. Diagnosis of xerostomia and salivary gland hypofunction is dependent upon a careful and detailed history and thorough oral examination. There exist many options for treatment and symptom management: salivary stimulants, topical agents, saliva substitutes, and systemic sialogogues. The aim of this review is to investigate the current state of knowledge on management and treatment of patients affected by xerostomia and/or hyposalivation.

Effect of a toothpaste containing triclosan, cetylpyridinium chloride, and essential oils on gingival status in schoolchildren: a randomized clinical pilot study.

OBJECTIVE: This randomized double-blind in vivo pilot study has evaluated the effects of a toothpaste containing fluoride (control) versus toothpaste containing fluoride, triclosan, cetylpyridinium chloride and essential oils (experimental) in controlling supragingival dental plaque and bleeding on probing in a sample of healthy schoolchildren. METHOD AND MATERIALS: In total, 48 children (8 to 10 years) were selected and randomly divided into two groups (experimental and control), using the two different toothpastes twice a day for 2 minutes each for a 4-week period. The investigation included an evaluation of plaque quantity, using the Turesky modified Quigley-Hein method, and bleeding on probing that was recorded dichotomously. The unit of analysis was set at the gingival site level. Plaque Index and bleeding on probing were analyzed using distribution tables and chi-square test. A generalized estimating equation was used to estimate the parameters of a generalized linear model with a possible unknown correlation between outcomes. RESULTS: In total, 40 schoolchildren completed the trial. Considering each group separately, a statistically significant difference in plaque scores was recorded for both treatments (z-test = 9.23, P < .01 for the experimental toothpaste; and z-test = 7.47, P < .01 for the control toothpaste). Nevertheless, the effect over time was higher for the experimental toothpaste than for the control one (3.38 vs 1.96). No statistically significant results were observed regarding bleeding on probing. CONCLUSION: The 4-week use of the experimental toothpaste seems to produce higher plaque reduction compared to fluoridated toothpaste without other antibacterial ingredients. This finding has to be confirmed in a larger study.

Lack of association between maternal periodontal status and adverse pregnancy outcomes: a multicentric epidemiologic study.

OBJECTIVE(S): The aim of this study was to explore the relationship between periodontal health and pregnancy outcomes in a large cohort of Italian postpartum women. METHODS: 750 postpartum women were enrolled in a case-control study within 5 days from delivery at three Italian obstetric clinics. Cases were defined as those mothers who delivered an infant weighing under 2500 g (LBW) and/or had premature delivery and/or delivered small for gestational age newborns (SGA) and/or experienced preeclampsia/pregnancy induced hypertension (PE/PIH) or preterm premature rupture of membranes (pPROM) during pregnancy. All women received comprehensive oral and dental examination. Associations between adverse pregnancy outcome and exposures of interest were evaluated by the use of multivariate logistic regression models to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: There was no significant difference between cases and controls with respect to country of birth, age, place of residence, educational achievement, smoking, and periodontal status. By definition, infant birth weight [2,750 g (IQR = 2,300-3,200 g) and 3,275, (IQR = 3,010-3,538 g) p < 0.001, respectively] and gestational age at delivery [259 days (IQR = 245-273) and 273 days (IQR = 266-280), p < 0.01, respectively] were significantly lower in cases than in controls. In multivariate analyses, a borderline association was found between poor obstetric outcomes and current smokers (OR: 1.5; 95% CI: 0.1-2.5). Finally, after adjusting for smoking status neither country of birth, nor age or place of residence or education or periodontitis were associated with a significantly increased risk of adverse pregnancy outcome. CONCLUSION(S): Our data failed to demonstrate the association between periodontitis and an adverse pregnancy outcome such as preterm birth, low birth weight, preeclampsia, intrauterine growth restriction, and premature rupture of membranes.

Dental patients' self-reports of xerostomia and associated risk factors.

BACKGROUND: Most studies regarding xerostomia focus on elderly people. Therefore, the authors conducted a study of dental patients 18 years or older to determine the prevalence of self-reported xerostomia and associated risk factors. METHODS: The authors sent a total of 2,200 questionnaires to four dental clinics to assess patients' self-reported xerostomia. They also collected sociodemographic data and information regarding personal behavior. They used logistic regression models to estimate odds ratios (OR) and 95 percent confidence intervals (CI) to explore the relationship between self-reported xerostomia and risk factors that reasonably might be expected to be associated with self-reported xerostomia. RESULTS: The overall prevalence of xerostomia in participants was 7 percent. Participants with burning-mouth sensations were associated with having higher odds of experiencing dry mouth (OR, 2.1; 95 percent CI, 0.9-5.2). Participants 51 years or older were significantly more likely to report having dry mouth than were younger participants (P < .04). The prevalence of self-reported xerostomia increased with increasing numbers of medications patients reported using. CONCLUSION: The authors found that medication use and age were highly significant risk factors for dental patients reporting xerostomia. CLINICAL IMPLICATIONS: Clinicians should interview their patients carefully regarding their use of medications and provide proper oral health care to improve xerostomia resulting from medication use.

Osteoporosis and bisphosphonate-related osteonecrosis of the jaw bone.

The aim of this longitudinal study is to present data from 76 female patients treated with bisphosphonates (BPs) for postmenopausal osteoporosis and referred to the Unit of Oral Diagnosis and Day Surgery of the University of Milano for diagnosis and treatment. All patients received a thorough oral examination. The diagnosis of osteonecrosis of the jaw bone (ONJ) was made from radiographic and clinical findings. 9% of individuals had BRONJ at first visit. Patients with dental or periodontal abscess were significantly more likely to develop BRONJ (OR: 2.9, 95% CI 0.5-15.9). Patients with osteoporosis receiving BPs may develop BRONJ, especially in the presence of an active infectious process in the mouth. Clinicians should carefully follow up on individuals receiving bisphosphonates therapy to avoid the occurrence of osteonecrotic lesions.

Dental and periodontal history of oncologic patients on parenteral bisphosphonates with or without osteonecrosis of the jaws: a pilot study.

OBJECTIVES: We tested the hypothesis that patients on bisphosphonates with ONJ might have a poorer dental and periodontal history than non-ONJ patients. Our aim was to retrospectively compare medical and oral history of patients on bisphosphonates with and without ONJ. STUDY DESIGN: A total of 39 oncologic patients on bisphosphonates were interviewed, examined, and had a panoramic radiograph taken. DMFT values and residual bone levels were calculated and compared for ONJ and non-ONJ patients. RESULTS: Twenty of 39 patients had ONJ. No statistical differences in caries or residual bone level as well as dental extractions were detected, although twice as many patients with ONJ underwent dental extractions. ONJ patients had received statistically more administrations of bisphosphonates compared to non-ONJ patients. CONCLUSION: A long history of bisphosphonate administration might represent a risk for ONJ onset.
