Concurrence of water and food insecurities, 25 low- and middle-income countries.

Objective: To investigate how water and food insecurity were associated in nationally representative samples of individuals from 25 low- and middle-income countries. Methods: We used data from the 2020 World Gallup Poll in which the Individual Water Insecurity Experiences Scale and the Food Insecurity Experience Scale had been administered to 31 755 respondents. These scales measure insecurity experiences in the previous 12 months. We classified individuals as water insecure if their score was ≥ 12 and food insecure if the Rasch probability parameter was ≥ 0.5. For estimating the proportions, we used projection weights. We estimated the relationships between binary and continuous measures of water insecurity and food insecurity for individuals within each country and region using multivariable logistic and linear regression models, adjusting for key socioeconomic characteristics including income, gender, age and education. Findings: Among the 18.3% of respondents who experienced water insecurity, 66.8% also experienced food insecurity. The likelihood of experiencing moderate-to-severe food insecurity was higher among respondents also experiencing water insecurity (adjusted odds ratio, aOR: 2.69; 95% confidence interval, CI: 2.43 to 2.98). Similar odds were found in Asia (aOR: 2.95; 95% CI: 2.04 to 4.25), Latin America (aOR: 2.17; 95% CI: 1.62 to 2.89), North Africa (aOR: 2.92; 95% CI: 2.17 to 3.93) and sub-Saharan Africa (aOR: 2.71; 95% CI: 2.40 to 3.06). Conclusion: Our results suggest that water insecurity should be considered when developing food and nutrition policies and interventions. However, more research is needed to understand the paths between these insecurities.

Implant surface roughness alterations induced by different prophylactic procedures: an in vitro study.

AIM: To evaluate surface roughness alterations at the smooth neck of dental implants after the use of eight different prophylactic procedures. MATERIALS AND METHODS: 50 tissue level implants (Institut Straumann AG, Basel, Switzerland) were used for the present investigation. The smooth collar of each implant was divided into two segments, each treated with one of eight cleaning procedures: use of a rubber cup (RCZ) or a brush (BZ) combined with an abrasive paste containing zirconium or a paste derived from perlite (RCP, BP); use of 2 composite resin burs reinforced by zirconium glass fibers (F1, F2); and use of an air-polishing system with glycine powder and two power settings (AP1, AP2). The qualitative alterations were recorded by means of a laser profilometer and the mean roughness (Ra ) and mean roughness profile depth (Rz ) were reported. Twenty untreated surfaces were used as controls. RESULTS: The implant collars treated with RCZ (Ra  = 0.33 µm, Rz  = 2.43 µm) or BZ (Ra  = 0.30 µm, Rz  = 3.70 µm) yielded the highest roughness values, followed by the surfaces treated with RCP (Ra  = 0.28 µm, Rz  = 2.02 µm), with BP (Ra  = 0.25 µm, Rz  = 2.16 µm) and by the use of F1 (Ra  = 0.27 µm, Rz  = 2.22 µm) and F2 (Ra  = 0.27 µm, Rz  = 2.04 µm). The lowest roughness values were observed in the AP1 (Ra  = 0.23 µm, Rz  = 1.60 µm) and AP2 (Ra  = 0.16 µm, Rz  = 1.06 µm) group, respectively. Implant collars treated with AP2 yielded statistically significantly lower (P = 0.01) Rz values compared with untreated surfaces. CONCLUSION: All tested procedures did not increase implant surface roughness significantly. Treatment with an air-powder abrasive system at high-pressure setting resulted in a smoothening of the implant collar surface.

Periodontal care as a fundamental step for an active and healthy ageing.

In the industrialized part of the world, an increasing number of people live the old age without too many restrictions due to illness or physiological impairment. This group is known as the young elderly. On the contrary, a consistent part of seniors develops a greater number of medical conditions and become more and more dependent, these are the old elderly. The first cause of tooth lost in industrialized word is periodontitis that generally strikes people older than 40 years and determines serious detriment of the stomatognatic organ. Smoking and stress are risk factors for periodontitis that are common and shared between young, adult, and older age. Diabetes mellitus, obesity, and osteoporosis are very frequent pathological situations in older age. They have been identified as cofactors in the progression of periodontitis. Many dental associations recognize the importance of continued research on oral fluids diagnostics and welcome the development of rapid point-of-care tests providing accurate measurements of clinically validated biomarkers. At present, well-studied molecules associated with host response factors and with derived tissue destruction mediators have been proposed as diagnostic biomarkers for periodontitis detected in the oral fluids.

Soft and hard tissues healing at immediate transmucosal implants placed into molar extraction sites with collagen membrane uncovered: a 12-month prospective study.

PURPOSE: To assess soft and hard tissues healing at immediate transmucosal implants placed into maxillary molar region with collagen membranes uncovered. MATERIALS AND METHODS: Twenty subjects received 20 immediate transmucosal implants placed in maxillary molar extraction sockets. Periimplant marginal defects were treated according to the principles of guided bone regeneration by means of deproteinized bovine bone mineral particles in conjunction with collagen membrane. Flaps were repositioned and sutured, allowing nonsubmerged, transmucosal soft tissues healing. The collagen membranes adapted around implant neck were uncovered. RESULTS: No implants were lost during the 1-year observation period yielding a survival rate of 100%. No postsurgical wound healing complications were observed. No degranulation of grafting material was reported. CONCLUSIONS: The results of this 12-month prospective study showed that the exposure of collagen membrane at time of the flap suturing does not represent a limitation for the soft and hard tissues healing at immediate transmucosal implants placed into maxillary molar extraction sites.

The state of food systems worldwide in the countdown to 2030.

This Analysis presents a recently developed food system indicator framework and holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience. Each theme is divided into three to five indicator domains, and indicators were selected to reflect each domain through a consultative process. In total, 50 indicators were selected, with at least one indicator available for every domain. Harmonized data of these 50 indicators provide a baseline assessment of the world's food systems. We show that every country can claim positive outcomes in some parts of food systems, but none are among the highest ranked across all domains. Furthermore, some indicators are independent of national income, and each highlights a specific aspiration for healthy, sustainable and just food systems. The Food Systems Countdown Initiative will track food systems annually to 2030, amending the framework as new indicators or better data emerge.

Feasibility analysis of an ultrasound on line diagnostic approach for oral and bone surgery.

During implant surgery procedures, surgical precision is an essential prerequisite for the functional and aesthetic success of the prosthetic crown to be placed on the dental implant. A modern implant surgical approach should be standardized as much as possible to guarantee extreme precision in the insertion of the implant into the upper and lower bone jaws. Among the most common surgical errors during implant surgery there is the over-preparation of the surgical alveolus with possible damage to the contiguous anatomical structures. To avoid this problem, in the recent years, there has been an increasing attention to the development of new control techniques. In this paper, we describe an innovative ultrasound approach, which exploits the integration of an electro-acoustic transducer with the surgical drill used for realizing the alveolus in the bone that will host the implant. Specifically, he proposed approach is based on the "time-of-flight" detection technique for measuring the thickness of the residual bone subjected to the drilling. In order to demonstrate the feasibility of the proposed approach, here we report on a detailed numerical analysis aimed at studying the propagation of ultrasonic waves through the drill-bit and through the involved tissues. The obtained results confirm the validity of our approach, and enable for a future first prototype implementation of a hi-tech surgical drill-bit, which in general is suitable not only for dental implant surgery but also for other uses in oral surgery, maxillofacial surgery and for bone surgery.

A 10-year retrospective analysis of marginal bone-level changes around implants in periodontally healthy and periodontally compromised tobacco smokers.

AIM: to compare the 10-year marginal bone loss rates around implants supporting single-unit crowns in tobacco smokers with and without a history of treated periodontitis. MATERIALS AND METHODS: in this retrospective controlled study, 40 tobacco smokers were divided into four groups of 10 patients each. Two groups of periodontally compromised (PC) patients and two groups of periodontally healthy (PH) patients were established. PC patients had been treated for their periodontal conditions before implant placement. All patients were enrolled in a regular, individually tailored maintenance care program. For the rehabilitation of PC and PH patients, two different types of implants were used (Nobel Biocare AB; Straumann Dental Implant System). The radiographic bone loss rate was calculated by subtracting the bone levels at the time of crown delivery from the bone levels at the 10-year follow-up. RESULTS: the mean age, mean full-mouth plaque score and full-mouth bleeding score and implant location were similar for the four groups. Implant survival rates ranged between 70% and 100%, without statistically significant differences between the four groups (P>0.05). Implants placed in PC patients yielded statistically significantly higher marginal bone loss rates compared with those in PH patients (P<0.05), independent of the implant system used. CONCLUSION: after 10 years, implants placed in tobacco smokers with a history of treated periodontitis and enrolled in a supportive therapy program yielded lower survival rates and higher marginal bone loss rates compared with those of implants placed in PH smokers. These outcomes were independent of the implant system installed or the healing modality applied.

Frictional keratoses on the facial attached gingiva are rare clinical findings and do not belong to the category of leukoplakia.

PURPOSE: To investigate the clinical and histologic features of frictional keratoses located exclusively on the facial attached gingiva and establish whether these belong to the category of leukoplakia. MATERIALS AND METHODS: Over a period of 15 years, 159 patients presenting with oral keratotic plaques, located exclusively on the facial attached gingival mucosa, excluding the edentulous alveolar ridge and retromolar pad area, were retrospectively selected. Clinical and histologic features and the symptoms and progression of these lesions were carefully assessed. RESULTS: The presence of oral frictional keratosis located exclusively on the facial attached gingival mucosa was clinically and immunohistologically diagnosed in 14 of 159 patients (8.8%). Eleven patients (78.5%) showed unilateral involvement, whereas 3 patients (21.5%) had bilateral involvement. The disappearance of the lesions was accomplished in only 9 of 14 patients, resulting from discontinuation of bad habits. Clinically, these lesions appeared as distinct, sharply demarcated, isolated, asymptomatic, homogeneous whitish-plaques that were neither removable nor painful. The plaques did not create discomfort, change shape, or develop into malignancy. Histologically, these plaques showed features superimposable to those present in benign alveolar ridge keratoses. CONCLUSION: The results highlighted that frictional keratoses on the facial attached gingival mucosa 1) are rare findings, 2) clinically appear as "true leukoplakia" but histologically have the same features as benign alveolar ridge keratoses, 3) have no propensity for malignant transformation, 4) have a good prognosis, and 5) have a specific cause, and resolution is accomplished if the frictional element is eliminated. Thus, these must be removed from the category of leukoplakia.

Predictive Periodontitis: The Most Promising Salivary Biomarkers for Early Diagnosis of Periodontitis.

The primary cause of tooth loss in the industrialized world is periodontitis, a bacterial anaerobic infection whose pathogenesis is characterized by composite immune response. At present, the diagnose of periodontitis is made by a complete status check of the patient's periodontal health; full-mouth plaque score, full-mouth bleeding score, probing depth, clinical attachment level, bleeding on probing, recessions, mobility, and migration are evaluated in order to provides a clear picture of the periodontal conditions of a single patient. Chair-side diagnostic tests based on whole saliva could be routinely used by periodontists for a very early diagnosis of periodontitis, monitoring, prognosis, and management of periodontal patients by biomarker detection, whose diagnostic validity is related to sensitivity and specificity. Recent paper reviews and meta-analyses have focused on five promising host derived biomarkers as candidate for early diagnosis of periodontitis: MMP-8 (Metalloproteinase-8), MIP-1α (Macrophage inflammatory protein-1 alpha), IL-1 ß (Interleukin-1 beta), IL-6 (Interleukin-6), and HB (Hemoglobin), and their combinations. Chair-side Lab-on-a-chip (LOC) technology may soon become an important part of efforts to detect such biomarkers in saliva medium to improve worldwide periodontal health in developed nations as well as in underserved communities and poor countries. Their applications in preventive and predictive medicine is now fundamental, and is aimed at the early detection of risk factors or the presence or evolution of the disease, and in personalized medicine, which aims to identify tailor-made treatments for individual patients. The aim of the present paper is to be informative about host derived periodontal biomarkers and, in particular, we intend to report information about the most important immune response derived biomarkers and Hemoglobin as candidates to be routinely utilized in order to obtain a chair-side early diagnosis of periodontal disease.

Subgingival dysbiosis in smoker and non­smoker patients with chronic periodontitis.

Periodontitis is one of the most common oral inflammatory diseases, and results in connective tissue degradation and gradual tooth loss. It manifests with formation of periodontal pockets, in which anaerobic and Gram­negative bacteria proliferate rapidly. Consequently, alteration of the subgingival microbiota is considered the primary etiologic agent of periodontitis. Previous studies have reported that smokers are at increased risk of periodontal disease, in both prevalence and severity, indicating that smoking is a risk factor for the onset and progression of the pathology. In the present study, 16S rRNA sequencing was employed to assess the subgingival microbiota in 6 smoker patients with chronic periodontitis, 6 non­smoker patients with chronic periodontitis and 8 healthy controls. The results demonstrated significant alterations in the microbial structure of periodontitis patients. High relative abundance of Parvimonans, Desulfubulbus, Paludibacter, Haemophilus, and Sphaerochaeta genera characterized subgingival microbiota of periodontitis patients, both smokers and non­smokers. Due to the high precision and sensitivity of the 16S rRNA sequencing method, analysis for low­abundant genera (including Pedobacter, Granulicatella, Paracoccus, Atopobium, Bifidobacterium, Coprococcus, Oridobacteriu, Peptococcus, Oscillospira and Akkermansia) was feasible, and revealed novel phylotypes associated with periodontitis. Of note, a major microbial community alteration was evident in smoker patients, suggesting an association between smoking and severity of subgingival dysbiosis. The present study confirmed that chronic periodontitis is a polymicrobial disease where changes in the equilibrium of subgingival microbiota contribute to severity of pathology.

Influence of Platform-Switched, Laser-Microtextured Implant on Marginal Bone Level: A 24-Month Case Series Study.

PURPOSE: The aim of this case series study was to evaluate clinical and radiographic changes of soft and hard tissues around tapered, platform-switched, laser-microtextured implants 24 months after crown placement. MATERIALS AND METHODS: Twenty tapered, platform-switched, laser-microtextured collar implants were placed in 20 patients. Full-mouth plaque score, full-mouth bleeding score, probing depth, and mucosal recession were recorded at the time of crown cementation and after 24 months follow-up. The marginal bone-level changes at the mesial and distal aspects of the implants were calculated by subtracting from baseline and 24-month implant marginal bone level. RESULTS: In terms of the full-mouth plaque score and full-mouth bleeding score, tapered, platform-switched, laser-microtextured implants showed statistically significant improvements at 6 months when compared to baseline (P < .001). Statistically significantly deeper probing depths (P < .001) were found when comparing baseline and at 24 months at mesial, lingual, and distal sites. However, no statistically significant difference was found at the buccal aspects (P = .064). Radiographic marginal bone loss at 2-year follow-up for tapered, platform-switched, laser-microtextured implants was 0.72 ± 0.16 mm and 0.67 ± 0.15 mm at the mesial and distal sites, respectively. CONCLUSION: Within the limits of this study, tapered, platform-switched, laser-microtextured implants maintained marginal bone level (less than 1 mm radiographic bone loss) as well as limited mucosa recession over a 2-year period.

Evaluation of efficacy of enamel matrix derivative in the treatment of intrabony defects: a 24-month multicenter study.

The aim of this prospective multicenter controlled clinical study was to evaluate the efficacy of Emdogain (Biora), an enamel matrix derivative (EMD), when combined with surgical treatment of periodontal angular defects, as compared to surgery alone, for up to 24 months of follow-up. The study was performed at six Italian universities and 11 private practices. Patients with one-, two-, or three-wall angular defects were enrolled if intrabony defect depth (IBD) was 4 mm or more and probing pocket depth (PPD) was at least 6 mm. They were randomly allocated to either test or control groups. The test group was treated by the simplified papilla preservation (SPP) flap plus Emdogain after root conditioning with ethylenediaminetetraacetic acid. The control group was treated by SPP alone. Plaque Index, Gingival Index, PPD, and periodontal attachment level (PAL) at surgical sites were assessed at the presurgical examination (baseline). IBD was measured intraoperatively after debridement. IBD was also evaluated with a computer-aided technique, from periapical radiographs. Plaque Index, Gingival Index, PPD, PAL, and IBD were assessed at 12 and 24 months postsurgery. Data were further divided in two subgroups according to baseline IBD (6 mm or less and more than 6 mm). The differences between each follow-up and baseline, and between groups at each follow-up, for the above parameters were evaluated by standard statistical methods. One hundred fifty-three patients were recruited, accounting for 195 intrabony defects: 83 patients (108 defects) and 70 patients (87 defects) were allocated to the test and control groups, respectively. All parameters were improved at both 12 and 24 months, compared to baseline in both groups. In the test group, IBD, PPD, and PAL at 12 months were significantly better than these parameters in the control group. The test subgroup with IBD of more than 6 mm at baseline displayed a better outcome when compared to the 6 mm or less IBD subgroup. No significant adverse events related to the use of Emdogain were reported. The use of EMD as an adjunct to periodontal surgery in the treatment of angular defects significantly enhanced the rate and degree of periodontal regeneration. The control group also displayed significant tissue regeneration, but at a slower rate compared to the Emdogain group. The surgical procedure itself, with its goal of maximum preservation of the regenerative potential of periodontal tissues, proved to be effective in the treatment of periodontal angular defects. Pockets with IBD greater than 6 mm showed major improvement when treated with Emdogain.

Validity and reliability of food security measures.

This paper reviews some of the existing food security indicators, discussing the validity of the underlying concept and the expected reliability of measures under reasonably feasible conditions. The main objective of the paper is to raise awareness on existing trade-offs between different qualities of possible food security measurement tools that must be taken into account when such tools are proposed for practical application, especially for use within an international monitoring framework. The hope is to provide a timely, useful contribution to the process leading to the definition of a food security goal and the associated monitoring framework within the post-2015 Development Agenda.

Crestal bone changes at teeth and implants in periodontally healthy and periodontally compromised patients. A 10-year comparative case-series study.

BACKGROUND: Limited data exist on the longitudinal crestal bone changes around teeth compared with implants in partially edentulous patients. This study sought to compare the 10-year radiographic crestal bone changes (bone level [BL]) around teeth and implants in periodontally compromised (PCPs) and periodontally healthy (PHPs) patients. METHODS: A total of 120 patients were evaluated for the radiographic crestal BL around dental implants and adjacent teeth at time of implant crown insertion and at the 10-year follow-up. Sixty patients had a previous history of periodontitis (PCPs), and the remaining 60 were PHPs. In each category (PCP and PHP), two different implant systems were used. The mean BL change at the implant and at the adjacent tooth at the interproximal area was calculated by subtracting the radiographic crestal BL at the time of crown cementation from the radiographic crestal BL at the 10-year follow-up. RESULTS: At 10 years after therapy, the survival rate ranged from 80% to 95% for subgroups for implants, whereas it was 100% for the adjacent teeth. In all eight different patient categories evaluated, teeth demonstrated a significantly more stable radiographic BL compared with adjacent dental implants (teeth BL, 0.44 ± 0.23 mm; implant BL, 2.28 ± 0.72 mm; P <0.05). Radiographic BL changes around teeth seemed not to be influenced by the presence or absence of advanced bone loss (≥3 mm) at the adjacent implants. CONCLUSIONS: Natural teeth yielded better long-term results with respect to survival rate and marginal BL changes compared with dental implants. Moreover, these findings also extend to teeth with an initial reduced periodontal attachment level, provided adequate periodontal treatment and maintenance are performed. As a consequence, the decision of tooth extraction attributable to periodontal reasons in favor of a dental implant should be carefully considered in partially edentulous patients.

Soft and hard tissue modifications at immediate transmucosal implants (with Laser-Lok microtextured collar) placed into fresh extraction sites: a 6-month prospective study with surgical reentry.

Histologic and clinical studies confirm that laser-microtextured implant collars favor the attachment of connective fibers and reduce probing depth and peri-implant bone loss when compared with machined collars. This prospective study aimed at assessing the alveolar dimensional changes after immediate placement of a transmucosal implant with a Laser-Lok microtextured collar associated with bone regenerative procedures. Thirteen implants were placed immediately into single-rooted extraction sockets. Peri-implant defects were treated with bovine-derived xenografts and resorbable collagen membranes. At 6-month surgical reentry, the Laser-Lok microtextured collar provided more favorable conditions for the attachment of hard and soft tissues and reduced the alveolar bone loss.

Predictive, preventive, personalised and participatory periodontology: 'the 5Ps age' has already started.

An impressive progress in dentistry has been recorded in the last decades. In order to reconsider guidelines in dentistry, it is required to introduce new concepts of personalised patient treatments: the wave of predictive, preventive and personalised medicine is rapidly incoming in dentistry. Worldwide dentists have to make a big cultural effort in changing the actual 'reactive' therapeutic point of view, belonging to the last century, into a futuristic 'predictive' one. The first cause of tooth loss in industrialised world is periodontitis, a Gram-negative anaerobic infection whose pathogenesis is genetically determined and characterised by complex immune reactions. Chairside diagnostic tests based on saliva, gingival crevicular fluid and cell sampling are going to be routinely used by periodontists for a new approach to the diagnosis, monitoring, prognosis and management of periodontal patients. The futuristic '5Ps' (predictive, preventive, personalised and participatory periodontology) focuses on early integrated diagnosis (genetic, microbiology, host-derived biomarker detection) and on the active role of the patient in which networked patients will shift from being mere passengers to responsible drivers of their health. In this paper, we intend to propose five diagnostic levels (high-tech diagnostic tools, genetic susceptibility, bacterial infection, host response factors and tissue breakdown-derived products) to be evaluated with the intention to obtain a clear picture of the vulnerability of a single individual to periodontitis in order to organise patient stratification in different categories of risk. Lab-on-a-chip (LOC) technology may soon become an important part of efforts to improve worldwide periodontal health in developed nations as well as in the underserved communities, resource-poor areas and poor countries. The use of LOC devices for periodontal inspection will allow patients to be screened for periodontal diseases in settings other than the periodontist practice, such as at general practitioners, general dentists or dental hygienists. Personalised therapy tailored with respect to the particular medical reality of the specific stratified patient will be the ultimate target to be realised by the 5Ps approach. A long distance has to be covered to reach the above targets, but the pathway has already been clearly outlined.

Treatment of infrabony periodontal defects using a resorbable biopolymer of hyaluronic acid: a randomized clinical trial.

OBJECTIVE: This randomized clinical study examined the use of hyaluronic acid to treat infrabony periodontal defects over a period of 24 months. METHOD AND MATERIALS: Forty subjects with a two-wall infrabony defect (probing depth [PD] >= 7 mm; clinical attachment level [CAL] >= 7 mm) were selected. The defects were randomly divided into two groups: sites treated with hyaluronic acid (test group) and those treated with open flap debridement (control group). RESULTS: The 12- and 24-month evaluations were based on clinical and radiographic parameters. The primary outcome variable was CAL. Test defects shows a mean CAL gain of 1.9 ± 1.8 mm, while the control defects yielded a significantly lower gain of 1.1 ± 0.7 mm. PD reduction was also significantly higher in the test group (1.6 ± 1.2 mm) than in the control group (0.8 ± 0.5 mm). Frequency distribution analysis of the study outcomes indicated that hyaluronic acid increased the predictability of clinically significant results (CAL gains >= 2 mm and PD reduction >= 2 mm) in the test group compared with the controls. CONCLUSIONS: The treatment of infrabony defects with hyaluronic acid offered an additional benefit in terms of CAL gain, PD reduction, and predictability compared to treatment with open flap debridement.

The effect of recombinant granulocyte colony-stimulating factor on oral and periodontal manifestations in a patient with cyclic neutropenia: a case report.

Cyclic Neutropenia (CN) is characterized by recurrent infections, fever, oral ulcerations, and severe periodontitis as result of the reduced host defences. The previous studies have established the effectiveness of recombinant granulocyte colony-stimulating factor (GCSF) to increase the number and the function of neutrophils in the peripheral blood in this disease. In a 20-year-old Caucasian female with a diagnosis of cyclic neutropenia, oral clinical examination revealed multiple painful ulcerations of the oral mucosa, poor oral hygiene conditions, marginal gingivitis, and moderate periodontitis. The patient received a treatment with G-CSF (Pegfilgrastim, 6 mg/month) in order to improve her immunological status. Once a month nonsurgical periodontal treatment was carefully performed when absolute neutrophil count (ANC) was >/=500/muL. The treatment with G-CSF resulted in a rapid increase of circulating neutrophils that, despite its short duration, leaded to a reduction in infection related events and the resolution of the multiple oral ulcerations. The disappearance of oral pain allowed an efficacy nonsurgical treatment and a normal tooth brushing that determined a reduction of probing depth (PD

Sublingual ranula: a closer look to its surgical management.

Ranulas have been managed by various surgical methods, and the optimal treatment is still controversial. The aim of this study was to analyze a group of 124 surgically treated patients with intraoral ranula to assess 3 different methods: sublingual gland removal combined with the ranula excision, conventional marsupialization, and a variant of the marsupialization technique usually performed in our departments. Recurrence rate was 0% after radical treatment, 25.8% after marsupialization, and 12% after modified marsupialization. We suggest that conservative methods should always be considered as treatment of superficial oral ranulas. The modification of the conventional marsupialization by suturing the edges of the pseudocyst before unroofing of the lesion was demonstrated to be a useful technical strategy that simplifies and accelerates the surgical procedures and probably contributed to preventing recurrences.
