Objective: The aim of this cross-sectional study was to assess the bias in estimating the prevalence of periodontitis due to partial-mouth periodontal examination protocols (PMPE) and to relate the ...severity and extent of periodontal damage to periodontitis misclassification when applying case definitions by Centres of Disease Control and Prevention and American Academy of Periodontology (CDC/AAP).
Materials and methods: A full-mouth periodontal examination (FMPE) was performed in 721 adults living in North Italy to identify moderate and severe periodontitis. These results were compared with those obtained with two PMPE protocols analyzing two interproximal sites on all teeth (fMB-DL) or four interproximal sites in two random diagonal quadrants (pMDB-MDL).
Results: Both PMPE systems estimated the prevalence of moderate periodontitis with limited bias (−2.79% for pMDB-MDL and −3.49% for fMB-DL), whereas produced larger relative biases for severe periodontitis (−28.74% versus − 14.55%). The percentage of under-recognition of existing periodontal disease was 8.9% under fMB-DL and 15.5% under pMDB-MDL. The diagnosis of moderate and severe periodontal disease was correctly assigned to individuals with on average 8% and 30% of pathological sites, respectively.
Conclusion: These findings suggest that PMPE systems provide high level of bias when using CDC/AAP case definitions.
The aim of this cross-sectional study was to explore sociodemographic, behavioral, and clinical factors associated with self-awareness of periodontal health. Data were collected from a representative ...sample of 736 adults (25-75 years old) in a city of Northern Italy who self-assessed gingival bleeding, oral malodor, and tooth mobility in a questionnaire and who underwent clinical periodontal examination and organoleptic evaluation. Approximately 50% of the subjects were aware of their actual gingival health status and oral odor. The logistic regression analysis revealed that females presented higher odds of correctly perceiving their gingival conditions and mouth odor, while those who were older and smokers had a greater probability of being less objective in reporting them. Tooth type and position in the dental arches were positively associated with self-perception of tooth mobility. These findings reflected a low level of self-awareness that may influence oral care-seeking behavior. Subjects may be unconcerned about their periodontal health condition or lack enough knowledge to be aware of it. This points to the need for planning strategies to improve education and knowledge about periodontal health, which, by enhancing self-perception of periodontal symptoms, could help everyone to seek treatment in the initial stage of the disease.
This study assessed the periodontal conditions of type 2 diabetes (T2DM) patients attending an Outpatient Center in North Italy and explored the associations between metabolic control and ...periodontitis. Periodontal health of 104 T2DM patients (61 men and 43 women, mean age of 65.3 ± 10.1 years) was assessed according to CDC/AAP periodontitis case definitions and Periodontal Inflamed Surface Area (PISA) Index. Data on sociodemographic factors, lifestyle behaviors, laboratory tests, and glycated hemoglobin (HbA1c) levels were collected by interview and medical records. Poor glycemic control (HbA1c ≥ 7%), family history of T2DM, and C-reactive protein levels were predictors of severe periodontitis. An increase in HbA1c of 1% was associated with a rise in PISA of 89.6 mm
. On the other hand, predictors of poor glycemic control were severe periodontitis, waist circumference, unbalanced diet, and sedentary lifestyle. A rise in PISA of 10 mm
increased the odds of having HbA1c ≥ 7% by 2%. There is a strong bidirectional connection between periodontitis and poor glycemic control. The inflammatory burden posed by periodontitis represents the strongest predictor of poor glycemic control.
Although increasing evidence is emerging on the contribution of chemical elements in periodontal health, no studies have concomitantly evaluated the ionic profile in gingival crevicular fluid (GCF) ...and saliva in relation to the underlying periodontal status. Our hypothesis is that these biofluids have distinctive ionic content. Therefore, the aim of this cross-sectional study was to analyze the elemental composition of GCF and saliva in order to explore which biological matrix and which combination of elements could discriminate between periodontitis and periodontal health. Twelve ions were analyzed in GCF and unstimulated saliva from 54 subjects (18 periodontally healthy, 18 untreated severe periodontitis and 18 treated severe periodontitis) using inductively coupled plasma-mass spectrometry (ICP-MS) and inductively coupled plasma-optical emission spectroscopy (ICP-OES). These analytical techniques were able to determine levels of sodium (Na), potassium (K), calcium (Ca) and magnesium (Mg), while the other elements were below the detection threshold. Na and K ions were detected at elevated concentration in untreated periodontitis compared with treated periodontitis and healthy periodontium. Ca was increased in untreated periodontitis, but the difference was not significant. In saliva, only Na was significantly associated with periodontitis. The combination of Na and K in GCF enabled the correct assignment of a subject to the periodontitis or healthy group. Based on these preliminary results, GCF demonstrated higher clustering potential than saliva.
Aim
There is a paucity of up‐to‐date data regarding prevalence and risk indicators of periodontitis in Italy. Therefore, the aim of this study was to evaluate the prevalence of periodontitis and its ...risk indicators among adults from an urban area in North Italy.
Material and Methods
This cross‐sectional survey used a stratified two‐stage probability sampling method to draw a representative sample of the adult population of the city of Turin. About 1600 individuals, 20–75 years old, were randomly selected and 736 subjects agreed to participate (47% of the sampled subjects). Clinical parameters were assessed using a full‐mouth protocol. Logistic models were applied to assess associations between periodontitis and its putative risk indicators. Age was included as restricted cubic spline.
Results
Based on CDC/AAP case definition, the prevalence estimates of severe and moderate periodontitis were 34.94% (95% CI: 31.23–38.74) and 40.78% (95% CI: 36.89–44.79). The probability of periodontitis increased in smokers (adjusted OR 2.06, 95% IC: 1.26–3.37, p = 0.004) and with age but leveled off in the 50+ year‐old group (p < 0.001).
Conclusion
Periodontitis was highly prevalent in the Turin population. The present data will enable development of appropriate public health programs and allocation of resources.

Aim
No epidemiological data on halitosis are available from Italy. Thus, the aim of this population‐based cross‐sectional study was to estimate the prevalence of halitosis in an urban adult ...population from North Italy and to explore related oral risk indicators.
Materials and Methods
The survey used a two‐stage probability sampling method to collect a representative sample of inhabitants, aged between 20 and 75 years, in the city of Turin. Seven hundred and forty‐four adults were clinically examined (47% of sampled subjects) for oral malodor and periodontal conditions. Using a standardized questionnaire social, health and halitosis‐related parameters were collected. Logistic models with interaction terms between tongue coating scores (TCS) and periodontal status were used to explore halitosis risk indicators.
Results
The prevalence estimate of halitosis according to the organoleptic assessment was 53.51% (95% CI: 48.55–58.50). A statistically significant correlation was found between organoleptic and gas chromatography measurements (p < 0.0001). Stronger associations between halitosis and periodontitis were observed in people having higher TCS: adjusted odds ratio considering low and high TCS in individuals with severe periodontitis were 2.95 and 20.77 (p ≤ 0.003).
Conclusions
Due to the high prevalence of halitosis in the Turin population, its diagnosis and management should be incorporated in comprehensive dental care.

Surface contaminants on customized implant abutments could trigger an inflammatory response in the peri-implant tissues. The aim of this randomized controlled study was to assess the radiographic ...bone changes around implants restored with customized, platform-switched abutments, with and without autoclave treatment, 12 months after definitive restoration. Dental implants were placed 1 mm subcrestally in 64 systemically healthy patients (mean age: 63.3 ± 10.0 years; 31 patients had a history of periodontitis) to replace single or multiple missing teeth. According to a randomization list, abutments were subjected to steam and autoclave sterilization (43 implants, test group) or steam cleaning alone (44 implants, control group). Periapical standardized radiographs were taken at implant placement, prosthetic abutment connection, and 12 months after definitive cement-retained restoration. All implants were clinically stable without any sign of infection at the 12-month follow-up. An average marginal bone loss of 0.25 ± 0.19 mm was found in the test group compared to 0.35 ± 0.23 mm in the control group (no statistically significant difference), while the percentage of bleeding sites was significantly higher in the control group (8.7% ± 13.1% vs 19.1% ± 19.8%; P = .035). Autoclave treatment of customized abutments seems to reduce the inflammatory response around subcrestally placed implants.Surface contaminants on customized implant abutments could trigger an inflammatory response in the peri-implant tissues.

Background
Recent evidence is supporting the notion of a microbiological and immunological continuum on the gum–gut axis in health and disease. Therefore, the purpose of this study was to assess the ...prevalence and risk indicators of periodontitis in patients with Crohn's disease (CD) or ulcerative colitis (UC) compared to age‐ and sex‐matched controls without inflammatory bowel disease (IBD).
Methods
A total of 180 IBD (117 CD, 60 UC, 3 IBD‐unclassified) and 180 healthy controls were compared for their periodontitis diagnosis (Centers for Disease Control and Prevention/American Academy of Periodontology CDC/AAP case definition) and full‐mouth periodontal parameters. In addition, explorative logistic regression models were performed.
Results
Significantly more patients with IBD had moderate/severe periodontitis (85.6% vs. 65.6%, p < 0.001) and severe periodontitis (36.7% vs. 25.6%, p < 0.001) than controls. Differences were higher in the 35–50 and 51–65 age groups, without significant changes between CD and UC. IBD subjects presented chances ∼3.5 higher of having moderate/severe periodontitis (p < 0.001). Significant variables associated with periodontitis in the whole sample were older age, presence of IBD, and higher full‐mouth plaque scores, whereas in the IBD group they were male sex, IBD‐associated surgery, and IBD duration and localization (pancolitis). Positive risk indicators for IBD were periodontitis severity and higher bleeding scores, while smoking was negatively associated with UC.
Conclusions
Relevant associations between IBD and periodontitis were found, being modified by CD and UC clinical characteristics. Preventive and therapeutic strategies involving the gum–gut axis should be enforced in IBD patients.

The aim of this study was to histologically examine any epithelial cell inclusions in submerged subepithelial connective tissue graft (SCTG) after clinical healing was achieved. A total of 16 ...patients with Miller Class I or II gingival recessions were consecutively treated with a bilaminar procedure. At 2 months after surgery, a gingival tissue specimen was harvested from all SCTG-treated sites and stained with hematoxylin-eosin. The histologic evaluation revealed connective tissue in active reorganization without epithelial inclusions in 14 of the 16 tissue specimens. In the remaining 2 specimens, epithelial islands were observed deep in the connective tissue. In one case they developed in a solid cystic space, while in the second case they were strictly integrated in the lamina propria. Complete recession coverage was obtained in 14 of the 16 treated defects, with a mean root coverage of 95.1% ± 14.2% at 12 months.
