RESUMO
BACKGROUND: Oral lichen planus (OLP) is an immune-mediated inflammatory chronic disease of the oral mucosa, with different patterns of clinical manifestations which range from keratotic manifestations (K-OLP) to predominantly non-keratotic lesions (nK-OLP). The aim of the study was to analyze the differences in the clinical, psychological profile and symptoms between Italian patients of the North and Central-South with K-OLP and nK-OLP. METHODS: 270 K-OLP and 270 nK-OLP patients were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS) were administered. RESULTS: The Central-South K-OLP (CS-K-OLP) patients reported a higher frequency of pain/burning compared with the K-OLP patients of the North (N-K-OLP) with higher scores in the NRS and T-PRI (p value < 0.001**). The CS-K-OLP and the CS-nK-OLP patients showed higher scores in the HAM-D, HAM-A, PSQI and ESS compared with the Northern patients (p value < 0.001**). Multivariate logistic regression revealed that the NRS and T-PRI showed the greatest increase in the R2 value for the CS-K-OLP (DR2 = 9.6%; p value < 0.001**; DR2 = 9.7% p value < 0.001**; respectively) and that the oral symptoms (globus, itching and intraoral foreign body sensation) and PSQI showed the greatest increase in the R2 value for the CS-nK-OLP (DR2 = 5.6%; p value < 0.001**; DR2 = 4.5% p value < 0.001** respectively). CONCLUSIONS: Pain and mood disorders are predominant in patients with OLP in the Central-South of Italy. Clinicians should consider that the geographical living area may explain the differences in oral symptoms and psychological profile in OLP.

OBJECTIVE: To evaluate the use of a Cannabis sativa oil in the management of patients diagnosed with primary burning mouth syndrome (BMS). DESIGN: Prospective, open-label, single-arm pilot study. SETTING: University hospital. SUBJECTS: Seventeen patients with diagnosed BMS were included. METHODS: Subjects were treated for 4 weeks with a full cannabis plant extract, which was prepared from standardized plant material (cannabis flos) in specialized pharmacies by means of Romano-Hazekamp extraction and was diluted in oil (1 g of cannabis in 10 g of olive oil). The primary outcome was the change in pain intensity (assessed by the visual analog scale, Present Pain Intensity scale, McGill Pain Questionnaire, and Oral Health Impact Profiles) at the end of the protocol and during the succeeding 24 weeks; the neuropathic pain was also investigated with a specific interview questionnaire (DN4-interview [Douleur Neuropathique en 4 Questions]). Levels of anxiety and depression were considered as secondary outcomes, together with reported adverse events due to the specified treatment. RESULTS: Subjects showed a statistically significant improvement over time in terms of a clinical remission of the oral symptoms. Levels of anxiety and depression also changed statistically, displaying a favorable improvement. No serious reactions were detailed. None of the patients had to stop the treatment due to adverse events. CONCLUSIONS: In this pilot evaluation, the C. sativa oil provided was effective and well tolerated in patients with primary BMS. Further bigger and properly defined randomized controlled trials, with different therapeutic approaches or placebo control, are needed, however.

BACKGROUND: In oral medicine, colchicine is a therapeutic alternative for idiopathic recurrent aphthous stomatitis (RAS), Behçet disease (BD), periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) syndrome, and mouth and genitals ulcers with inflamed cartilage (MAGIC) syndrome. The present review aims to evaluate reliability of colchicine against recurrent oral ulcers. METHODS: A systematic review was conducted, with the following PICO (Patient, Intervention, Control, Outcome) question: "In populations with idiopathic or secondary recurrent oral ulcers, is colchicine more effective in improving pain and accelerating healing, compared to other intervention or placebo?" RESULTS: Seven RCTs and 3 OCTs were considered eligible. Four RCTs focused on BD, two RCTs and three OCTs on RAS, and one RCT on PFAPA syndrome. Heterogeneity between RCTs prevented from meta-analysis. Regarding BD, no significant difference between colchicine and placebo was found in two of three placebo-controlled RCTs, whereas the third RCT showed benefit. A comparative RCT found ciclosporin more effective than colchicine for oral lesions of BD. One open-label RCT showed promising but partial results on colchicine in reducing PFAPA attacks, when compared to corticosteroids. Concerning RAS, colchicine appeared less effective than clofazimine, thalidomide and dapsone, and with outcomes similar to low-dosage corticosteroids but higher gastric discomfort than prednisolone. One OCT reported positive results compared with no treatment but a RCT found no difference with placebo. CONCLUSION: Role of colchicine as treatment for idiopathic or secondary recurrent oral ulcers is still controversial. Further standardized RCTs and crossover trials are needed.

OBJECTIVES: The aim of this randomized, parallel-design, clinical trial was to investigate the effectiveness of an intensive plaque control programme with sonic versus manual toothbrushing on clinical outcomes and gingival crevicular fluid (GCF) levels of matrix metalloproteinases (MMP) in desquamative gingivitis (DG) patients. METHODS: A total of 32 patients affected by DG secondary to oral lichen planus (OLP) were consecutively recruited and randomly assigned to a test (n = 16) and control (n = 16) group. Both groups were enrolled in an intensive control programme comprising supragingival scaling and polishing, and brush-specific instructions for a period of 8 weeks. The treatment of interest (test) was the use of a sonic-powered toothbrush, and the standard treatment (control) was the utilization of a soft-bristle manual toothbrush for twice-daily home oral hygiene procedures. Periodontal parameters, patient-centred outcomes, MMP-1 and MMP-9 GCF levels were evaluated at baseline and 8 weeks after starting the programme. RESULTS: The plaque control programme resulted in statistically significant reduction in periodontal parameters with consequent improvement in the clinical features, painful symptoms and severity of DG lesions in both groups (all P < 0.001). When a sonic toothbrush was used, there was a more significant decrease in clinical indices, mucosal disease scores and GCF levels of MMP-1 and MMP-9. CONCLUSIONS: This clinical trial reported the effectiveness of a combined protocol based on professional oral hygiene and supervised toothbrushing in OLP patients with DG. The daily use of a sonic toothbrush would seem to perform better in the short term.

Sjögren's syndrome (SS) is a multisystem autoimmune disease characterized by hypofunction of the salivary and lacrimal glands, frequently relieved with symptomatic treatments, such as saliva substitutes, eye lubricants, and cholinergic stimulators. The aim of this pilot randomized placebo-controlled study was to estimate the effects of laser acupuncture on salivary flow rates in patients with severe hyposalivation due to SS. A prospective cohort of 26 female patients affected by SS has been evaluated. The laser therapy equipment used was the Pointer Pulse, emitting light in the red visible spectrum (650 nm), with a power of 5 mW and an irradiation time of 120 s per acupoint, in an area of 3.14 mm(2) (fluence = 19.2 J/cm(2), power density = 0.16 W/cm(2), total dose = 0.6 J). The following acupuncture points were stimulated bilaterally: LI 2 Erjian, ST 5 Daying, ST 6 Jiache, ST 7 Xiaguan, SI 19 Tinggong, and BL 13 Feishu. True laser acupuncture led to a significantly higher amount of saliva production, measured after the end of the protocol (5 weeks), and during the 6-month follow-up period. The results are stable from the end of the protocol until the 3rd month of follow-up; during the last control, a slight but significant decrease in production has also been shown. This preliminary study proposes laser acupuncture as a possible treatment for improving salivary flow rates in patients with SS, but further validation on a larger sample is still necessary.

BACKGROUND: Only few studies on tongue lesions considered sizable populations, and contemporary literature does not provide a valid report regarding the epidemiology of tongue lesions within the Italian population. In this report, the histopathological and clinical appearance of 1.106 tongue lesions from northern Italians are described and discussed. MATERIAL AND METHODS: The case records of patients referred for the diagnosis and management of tongue lesions, from October 1993 to October 2013, were reviewed. Histological data were also obtained and blindly re-examined. RESULTS: For instance, a biopsy performed on a lingual ulcer has a strong predicting association with a carcinoma, whereas a biopsy on a white lesion predicts for a leukoplakia or oral lichen planus. Moreover, a biopsy of erosion is representative of bullous diseases, whereas a biopsy on a verrucous-papillary lesion is significant for fibroma. Furthermore, carcinomas occur in the majority of cases on the lingual edge or pelvis, oral lichen planus is mainly seen on the edge, and fibromas mostly on the lingual tip. CONCLUSIONS: The high frequency of tongue involvement of such different diseases emphasizes the importance of histological characterization and that some diseases occur more frequently than others, with a peculiar clinical aspect and a more common area. In fact our survey can help the clinician in advancing diagnostic hypothesis, on the basis of the elementary lesion and its site of involvement.

PURPOSE: The surgical removal of mandibular third molars is frequently accompanied by significant postsurgical sequelae, and different protocols have been described to decrease such adverse events. The aim of this study was to investigate the performance of piezosurgery compared with traditional rotating instruments during mandibular third molar removal. PATIENTS AND METHODS: A single-center, randomized, split-mouth study was performed using a consecutive series of unrelated healthy patients attending the Oral Surgery Unit of the University of Turin for surgical removal of bilateral mandibular third molar teeth. Each patient was treated, at the same appointment, using bur removal on 1 side of the mandible and a piezoelectric device on the contralateral side. The primary outcomes reported were postoperative pain, objective orofacial swelling, and surgical duration; secondary outcomes were gender, age, and possible adverse events. Analysis of variance or paired t test was used as appropriate to test any significant differences at baseline according to each treatment subgroup, and categorical variables were analyzed by χ(2) test. RESULTS: The study sample consisted of 100 otherwise healthy patients. The mean pain evaluation reported by patients who underwent surgery with piezosurgery was significantly lower than that reported after bur (conventional) removal, reaching statistical difference after 4 days (P = .043). The clinical value of orofacial swelling at day 7, normalized to baseline, was lower in the piezosurgery group (P < .005). The average surgical duration was significantly shorter in the bur group than in the piezosurgery group (P < .05). Three patients having bur removal developed short-term complications (2 dry sockets and 1 temporary paraesthesia), which totally resolved by 4 weeks. CONCLUSIONS: To date, this prospective investigation is the largest reported split-mouth study on piezosurgery for lower third molar tooth removal. This study also compared surgeons with different degrees of experience. It is evident that using a piezoelectric device can enhance the patient experience and decrease postoperative pain and swelling.

Oral lichen planus (OLP) is an inflammatory disease that can be painful, mainly in the atrophic and erosive forms. Numerous drugs have been used with dissimilar results, but most treatments are empirical. However, to date, the most commonly employed and useful agents for the treatment of OLP are topical corticosteroids. The study objective was to detail the clinical effectiveness of low-level laser therapy (LLLT) for the management of OLP unresponsive to standard topical therapy. The authors studied a prospective cohort of 30 patients affected by OLP, who received biostimulation with a 980-nm gallium-aluminum-arsenide (GaAIAs) diode laser (DM980, distributed by DMT S.r.l., Via Nobel 33, 20035, Lissone, Italy). Outcome variables, statistically evaluated, were: the size of lesions; visual analogue score of pain and stability of the therapeutic results in the follow-up period. Eighty-two lesions were treated. We reported significant reduction in clinical scores of the treated lesions and in reported pain. No detailed complications or therapy side effects were observed during the study. As previously reported by our group with a preliminary report, this study suggests that LLLT could be a possible treatment choice for patients with unresponsive symptomatic OLP, also reducing the possible invasiveness correlated with other therapies.

Necrotizing gingivitis (NG) is an acute inflammatory process with an estimated prevalence of less than 1%. The treatment of choice is usually antibiotics in addition to periodontal treatment. This scoping review aims to detail extent and type of proof related to NG in paediatric patient; moreover, a decision tree protocol was developed to define NG management in paediatric patients based on the presence or absence of systemic compromission. In addition, we also propose the use of ozone treatment as an adjuvant therapy. Seven papers (3 case reports, 2 guidelines, and 2 reviews) were selected for evaluation by reading the full texts. This review outlines the lack of research on the treatment of NG in paediatric patients; we, however, demonstrate the efficacy of the decision tree protocol by describing two case reports in which patients were treated with antibiotics according to the presence or absence of systemic involvement through the implementation of an individualized therapeutic approach, with periodontal ozone therapy. Moreover, the supportive use of this molecule in the management of NG can be a valuable tool in the healing of gingival tissues.
RESUMO
BACKGROUND: Oral potentially malignant disorders (OPMD) are associated with the risk of malignant transformation (MT) into oral cavity carcinoma (OCC). Oral lichen planus (OLP) is one of the most common OPMDs in western countries. Although there is a substantial amount of research on progression to cancer, a specific analysis of the clinical characteristics and prognosis of cancer developed in patients with a history of OLP versus patients without a history of OLP has not been investigated so far. METHODS: Retrospective evaluation of 82 patients treated for OCC with a known history of OLP compared to a representative sample of 82 patients treated for OCC without a known history of LP. Comparative analyses were performed on age at presentation, sex, TNM staging, clinical characteristics, pathology characteristics, 2- and 5-year overall survival (OS), and disease-free survival (DFS). RESULTS: It was shown that patients with a history of LP were significantly younger at first presentation than patients without a history of LP (mean age difference 6.7 years, 95% CI 3.1-10.3, p < 0.05). Also, patients with a history of OLP were in higher proportion females. The main pathological stage at presentation was significantly lower in the OLP group (p < 0.05). The 2-year survival analysis showed that DFS and OS were significantly lower in patients without a known history of OLP, with a hazard ratio (HR) of 3.1 (95% CI 1.4-6.8) and HR of 2.6 (95% CI 1.3-5.3), respectively. The 5-year survival analysis showed that DFS and OS were significantly lower in patients without a known history of OLP, with a hazard ratio of 3.1 (95% CI 1.6-6.2) and of 2.9 (95% CI 1.5-5.6), respectively. CONCLUSIONS: Cancer arising from OLP has peculiar characteristics compared to cancer in naïve patients. It most commonly affects younger patients, women, and nonsmokers. It is usually diagnosed at earlier stages and appears to have less aggressive behavior at presentation. Moreover, when 2- and 5-year survival is analyzed, it appears that patients in OLP group have an overall and a disease-free survival advantage. These results suggest that cancer from OLP is less aggressive and thus has a potential biological difference with cancer arising in non-OLP patients. Further clinical and basic investigations are needed to confirm the results of this study.

OBJECTIVES: Only few studies on gingival lesions considered large enough populations and contemporary literature does not provide a valid report regarding the epidemiology of gingival lesions within the Italian population. The histopathological and clinical appearance of 538 gingival lesions from northern Italians are described and discussed here. STUDY DESIGN: The case records of patients referred for the diagnosis and management of gingival lesions, from October 1993 to October 2009, were reviewed. Data regarding the histological type of lesion were also obtained from the biopsy register for each case, and blindly re-examined. RESULTS: We reported a greater frequency of benign lesions (reactive and/or inflammatory) in non-plaque/non-calculus induced gingival disorders. We confirmed an unambiguous prevalence of oral squamous cell carcinoma above all other malignant neoplasia, and a prevalence of neoplastic malignant lesions in the maxilla, with a slight increase in females and a drift of the incidence peak from the seventh to the eighth decade. There was a prevalence of precancerous gingival lesions in the maxilla, with a higher incidence in females and with a drift from the sixth to the seventh decade. We also reported a prevalence of oral lichen planus and lichenoid lesions as major manifestations of desquamative gingivitis. CONCLUSIONS: The high frequency of gingival involvement of such different diseases emphasizes the importance of histological characterization and differential diagnosis for periodontists, but more prospective studies are needed to better describe the true incidence of the non-plaque related gingival diseases.

OBJECTIVES: This article aimed to evaluate the clinical efficacy of a nonantibiotic biofilm-removal formulation based on NitrAdine (PerioTabs), combined with a regular home oral hygiene regimen, in Caucasian patients with gingivitis. MATERIALS AND METHODS: A sample of 60 patients were included in this clinical prospective study. All selected subjects underwent regular prophylaxis and professional oral hygiene at baseline; 30 days later, they were recalled for the measurements of the reference parameters about bleeding on probing (full-mouth bleeding upon probing score [FMBS]) and plaque index (full-mouth plaque score [FMPS]); no other clinical procedure was performed. Consequently, half of the patients (n = 30) were instructed to use PerioTabs for 10 days. The remaining patients (n = 30) were used as the negative control, only instructed to continue with their usual oral hygiene regimen. Fifteen days after, the clinical parameters of FMBS and FMPS were re-evaluated in both groups. RESULTS: Changes in the scores of clinical indices FMBS and FMPS were calculated and compared. A significant difference between pre- and post-values, for both FMBS and FMPS, was noticed in the test group; in particular, the bleeding index value demonstrated the more significant changes: 22 participants showed a clinically meaningful improvement, and 5 had a small improvement. Only three patients had no evidence of change. In addition, 50% of patients had a reduction in plaque levels. No side effects were reported. CONCLUSIONS: The adjunctive use of 10-day PerioTabs treatment in the daily oral hygiene routine seemed to be efficient in reducing gingival bleeding and plaque accumulation, with absence of adverse effects. These results should be confirmed in studies with a larger number of participants following a controlled-blinded design.
RESUMO
PURPOSE: To test the hypothesis that cigarette smokers develop oral potentially malignant disorders or carcinomas in preferential anatomical subsites. METHODS: The association of smoking habit with the presence of oral lesions in specific anatomical subsites was assessed in 123 patients using the odds ratio analysis. RESULTS: When compared to all the other subsites, the relative frequency of smokers with lesions was higher in the buccal mucosa and in the floor of the mouth (FOM) (P=0.002 and P=0.005), while it was lower in the tongue (P<0.0005). Smokers were about 7 years younger than non-smokers (P=0.008). CONCLUSIONS: The association of smoking and age suggests that smoking may contribute to generate a field of injury that leads to lesions in shorter periods than other causes. The stronger relationship of smoking with lesions in the buccal mucosa and FOM than in the tongue suggests that tissue characteristics mediate the effects of tobacco.

OBJECTIVES: To revise the clinical features of the recurrent intraoral herpetic infection (RIOH) with respect to precipitating factors, demographic, clinical features and outcome. STUDY DESIGN: Fifty-eight, unrelated Caucasian, immunocompetent patients with positive laboratory test for intraoral Herpes simplex virus infection were studied. RESULTS: The mean age in the women's group (n=42) was 41.23 years (± 21.73) and in the men's group was 32.25 years (±15.68). Possible trigger factors were identified in 9 cases (15.5%). General symptoms were noted in 20 cases (34.48%). Most of patients in this study presented multiple lesions. 14 patients had vermillion lesions associated with intraoral lesions. In most of the cases both fixed and mobile mucosa was concomitantly involved. Treatment was prescribed in order to control the symptoms and to shorten the evolution with minimal side effects. CONCLUSIONS: Intraoral secondary herpetic infection could be polymorphous and sometimes associated with general symptoms. The recognition of its atypical features may prevent unnecessary and costly investigations and treatments for unrelated though clinically similar-appearing disorders.

This case report described a modified bilaminar technique for treating a single gingival recession. Patient presented a gingival recession in a maxillary canine. Tooth was in a buccally prominent position and soft keratinized tissue apical to the recession was reduced but still present. A split-full-split thickness trapezoidal flap was designed. Root's surface was prepared with curettes. Epithelial-connective tissue graft was harvested from the palate with reduced dimension. After deepithelialization, the graft was placed with a fibrin-fibronectin system at the maximum root coverage level, and the flap coronally advanced and sutured. At 3-year follow-up control, the free gingival margin was still stable at the postsurgery position, with a thicker biotype corresponding to the grafted area, with no probing and a suitable aesthetic result.
RESUMO
This article describes a nonsurgical approach for treating gingival recessions and increasing gingival thickness around the natural teeth. Two female patients, presenting gingival recessions at the maxillary frontal teeth, were treated. Patient #1 had a discrepancy among the central maxillary incisors' gingival margin, and tooth UL1 needed to be restored. Patient #2 presented a buccal gingival recession at tooth UL3. In both cases, the sulcular gingival margin was gently disephitelized with a diamond bur leaving the soft tissue healing by itself. After 4 weeks, the procedure was reperformed. After 6 months, the gingival margins appeared thicker and a creeping attachment was achieved in both cases, obtaining gingival symmetry, related to the adjacent or contralateral teeth, and root coverage. Gingival asymmetry, gingival recessions, and gingival thickness may be improved by means of a guided gentle nonsurgical stimulation, providing creeping attachment in the natural and also restored teeth, with a healthy and stable tissue after 24 months of follow-up.
RESUMO
Objective: The purpose of this prospective analysis was to evaluate the efficacy of erbium-substituted yttrium aluminum garnet (Er:YAG) laser compared with that of conventional surgery, regarding the long-term outcome of nondysplastic oral leukoplakias (OL). Background: To date, this comparison has never been performed. Methods: Patients were randomly allocated to two different groups: some underwent surgical excision with traditional scalpel (Group TrSc) and others underwent an ablative session with Er:YAG laser (Group Las), with these modalities: 1.5-W power, 150-mJ pulse energy, 10-Hz frequency, 500-µs pulse duration, and 0.9-mm spot size. During the follow-up period, the evolution of the OL was listed as (1) healing: if novel lesions did not appear in the same place of the surgery and (2) recurrence: if a new mucosal change has been detailed in the equivalent place of the primary disease. Results: One hundred seventeen lesions were treated. Fifty-eight lesions underwent surgery with traditional scalpel, whereas 59 underwent laser surgery. Follow-up ranged from 24 to 108 months (median of 58). Healing was detailed for 52.99% (n = 62) of the 117 OL, with no statistical differences between the two randomized groups. Conclusions: It seems reasonable to consider the Er:YAG laser as effective as traditional scalpel in terms of healing for OL, with the same rate of recurrences in a period of almost 5 years.

OBJECTIVE: The aim of this prospective study was to estimate the effects of Erbium substituted: Yttrium Aluminium Garnet (Er:YAG) laser, compared with traditional scalpel, on the early postoperative sequelae of nondysplastic oral lesion removal. BACKGROUND DATA: There is limited evidence that laser surgery could exhibit advantages over scalpel in oral mucosal surgery. METHODS: The investigators studied a cohort of 344 patients; 394 lesions were randomized and treated. Outcome statistically evaluated variables were: age, gender, the site and size of investigated lesions, visual analogue score (VAS) of pain, the Oral Health Impact Profile questionnaire (OHIP-14) and the Quality of Life test (QOL), and number of analgesics taken in the 1st week after surgery. RESULTS: Significant differences were found if considering the surgical time, VAS, and QOL and OHIP-14 questionnaires; regarding those data, the Er:YAG laser appeared to be faster and less painful than traditional scalpel (p < 0.05). For bigger lesions, patients statistically took more painkillers if they had undergone traditional surgery. Considering the site of the treated lesions, Er:YAG laser was less painful, especially in the gingiva and palate (p < 0.05). CONCLUSIONS: This is the first randomized controlled surgical trial reported for the management of nondysplastic oral lesions with the use of an Er:YAG laser. With many limitations, the present report identifies significant difference in the immediate postoperative surgical period between the two treatments, meaning that the Er:YAG laser seemed to be less painful, and better accepted by patients, than traditional scalpel.
