RESUMEN
OBJECTIVES: The loss of hard dental tissue due to recurrent acid challenges and mechanical stresses without bacterial involvement is known as erosive tooth wear (ETW). Many studies in the literature have concentrated on variables that may affect the ETW process and prevent its occurrence or reduce its advancement. However, to date, no previous systematic review has evaluated the role of calcium in preventing ETW. Therefore, the purpose of the present systematic review was to review and critically appraise the scientific evidence regarding the role of calcium formulations in the prevention of ETW. METHODS: The review protocol was registered in the PROSPERO international prospective register of systematic reviews (Ref: CRD42021229819). A literature search was conducted in electronic databases to identify in situ randomized controlled trials evaluating the prevention of ETW following the application of calcium formulations. The outcomes studied included mean enamel loss, surface microhardness, surface roughness, mean erosion/softening depth, mineral loss/precipitation and remineralization. Study characteristics and outcomes of included studies were summarized. Cochrane's risk-of-bias tool 2.0 was used to assess the quality of eligible studies, and meta-analysis using a random effects model was performed. RESULTS: The search retrieved 869 studies of which 21 were considered eligible. Regarding the results of the quality assessment for potential risk of bias in all included studies, overall, 5 studies were considered as being at low risk, another 12 at unclear risk and 4 at high risk of bias. The findings of the studies showed that the addition of calcium in juice drinks led to reduced enamel loss, with blackcurrant juice presenting 2.6 times statistically significant less enamel loss compared to orange juice (p = 0.0001, I2 = 89%). No statistically significant difference in mean surface microhardness of eroded enamel was recorded between chewing gum with or without casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) (p = 0.31, I2 = 71%). Contradictory were the results regarding the effect of milk and CPP-ACP pastes on prevention of ETW. CONCLUSIONS: Calcium formulations play an important role in ETW prevention, mainly through their addition to acidic drinks.

PURPOSE: With success rates comparable to that of root canal treatment, vital pulp therapy (VPT) has gained clinical interest and has been used in the management of young permanent teeth with inflamed pulps. The aim of the present study was to retrospectively evaluate the radiographic success of VPT in young first permanent molars 24 months post-treatment and correlate findings with tooth and treatment-related characteristics. MATERIALS AND METHODS: Dental records of all patients with first permanent molars which received VPT in the Department of Paediatric Dentistry (National and Kapodistrian University of Athens) were retrieved. Demographic characteristics and data regarding the treatment performed were recorded. Patients' radiographs were evaluated at 6, 12 and 24 months post-treatment by two qualified paediatric dentists blinded regarding the treatment performed. Radiographic success, reasons for failure and continuation of root development were evaluated. Differences were tested using the Χ2 and Student's t-test, and possible correlations were determined by calculating the odds ratio. RESULTS: Overall radiographic success rate at 24 months was 77%, ranging between 50% for direct pulp capping and 92% for full pulpotomy. Differences were not statistically significant. Continuation of root development was recorded in almost 1/3 of the teeth and completion in almost 1/5. No statistically significant association was recorded between the outcome and any tooth and treatment-related variables. CONCLUSION: VPT seems to be a reliable option in the long term for the treatment of deep carious lesions in young permanent molars.

OBJECTIVES: The aim of this overview of reviews was to retrieve and evaluate the available evidence concerning the prevalence and association between gastroesophageal reflux disease (GERD) and erosive tooth wear (ETW). DATA: A literature search was conducted in electronic databases and relative systematic reviews with or without meta-analyses were located. Updated supplemental search was also undertaken to identify additional primary studies. SOURCES: Medline (via Pubmed), Embase, Scopus, Cochrane Register of Systematic Reviews, PROSPERO and Epistemonikos.org database were searched. Additional search of the gray literature, abstracts of conferences and meetings as well as manual search of the reference lists of retrieved studies, was also performed. STUDY SELECTION: The search retrieved 116 systematic reviews of which 10 were considered eligible and eight additional primary studies. CONCLUSIONS: GERD constitutes a risk factor for ETW and there is a positive association between the two conditions. In the present overview, despite the heterogeneity between studies and the low level of evidence, it was clearly supported that individuals with GERD have an increased probability of also presenting with signs of ETW. In special groups of population, a high association was found between GERD and ETW. The geographic location may affect the association between GERD and ETW, while regarding the effect of flow rate, buffering capacity of saliva and oral microbial changes caused by GERD, the results were controversial. CLINICAL SIGNIFICANCE: Appropriate preventive dental care should be considered for individuals with GERD and a multidisciplinary medical and dental approach for the management of individuals with ETW is advised. The results of this study can be used by dentists dealing with typical and atypical GERD signs and symptoms in the oral environment, but also by the physicians and gastroenterologists who need to motivate their patients for oral examination.

Alveolar fractures treatment includes repositioning of displaced segments and splinting. In children, splinting procedures may occasionally present clinical problems resulting from fewer teeth available for splinting or presence of occlusal disturbances. An alternative clinical approach for splinting in alveolar fractures of primary dentition is described. CLINICAL CASE: A 4.5-year-old girl was referred to our clinic 8 hours after a fall accident. Clinical examination revealed mandibular alveolar process segmental fracture in the right canine area with frontal dislodgement of the labial cortical bone resulting to occluding inability. The area was anaesthetized, cleaned and the dislodged bone was manually repositioned, followed by an EVA copolymer splint for fixation as a result of patient's deep bite impeding regular wire-composite splint. The cap splint that was fabricated on a cast made after an alginate impression, was set on the mandibular dentition and immobilized in the primary molars with acid-etch adhesive and flowable resin composite. Following splint removal after 4 weeks and follow-up visits, successful healing was observed clinically and radiographically with no pathological signs and symptoms. CONCLUSION: The described alternative splinting method in alveolar fractures of primary dentition is a valuable clinical tool for peediatric dentists, easily accepted by children in cases where regular splinting methods cannot be used.

OBJECTIVE: Localized juvenile spongiotic gingival hyperplasia (LJSGH) is a painless gingival swelling that histologically exhibits hyperplasia of the non-keratinized stratified squamous epithelium, intercellular edema and spongiosis of the spinus layer, and exocytosis of inflammatory cells. LJSGH pathogenesis remains to be elucidated, while a possible origin from the gingival sulcus epithelium is nowadays proposed. STUDY DESIGN: We report two cases of LJSGH with immunohistochemical evaluation of cytokeratins (CKs) 18 and 19. RESULTS: Both cases concerned 12-year-old boys, who presented with a well-circumscribed bright red pedunculated papillary swelling on the marginal gingiva of the left maxillary lateral incisor. With the provisional diagnosis of LJSGH, the lesions were excised under local anesthesia and histological examination supported the final diagnosis of LJSGH. In both cases, the lesional epithelium showed intense and mild positivity for CK19 and CK18, respectively, while the adjacent normal gingival epithelium expressed CK19, but not CK18, only in the basal cell layer. The postoperative course was uneventful in both patients and no recurrence has been reported. CONCLUSION: LJSGH is a recently introduced entity that is worth attention in the clinical pediatric dentistry. Clinical and histological examination is required for the final diagnosis, while immunohistochemistry has shed light to LJSGH pathogenesis.

PURPOSE: To present the 15 years of experience after closed treatment of condylar fractures in children, by evaluating the short- and long-term results and propose treatment modalities. MATERIAL AND METHODS: Data were retrieved for all young patients with condylar fractures who were treated from 2000 to 2014. Gender, age of patient, date of injury, type of fracture, treatment provided, and follow-up were registered. RESULTS: A total of 84 patients (mean age: 8.9 years) with 106 condylar fracture sites were included in the study. In 80 cases (95.2%), treatment was nonsurgical, with or without intermaxillary fixation, followed by kinesiotherapy. An intraocclusal block was additionally placed in 19 cases. Open reduction was selected in 4 cases. All condylar fractures healed without functional or esthetic complications, with the exception of 2 patients (2/80, 2.5%). Therefore, in late follow-up, no subjective symptoms were recorded, and a functional well-contoured condylar process was observed in all X-rays. Slight asymptomatic mandibular deviation was recorded in wide mouth opening in 29.1% of the patients. CONCLUSIONS: Conservative treatment of condylar fractures is the treatment of choice in children. However, the child's age, adequacy of function of the mandible, degree of displacement or dislocation of the condylar fragment, and need for active kinesiotherapy should be considered in all cases.

INTRODUCTION: Hand-Schüller-Christian disease (HSC) is the unisystem multifocal form of Langerhans Cell Histiocytosis (LCH) and is primarily seen in infants and children. CASE REPORT: An 8-year-old boy was referred for acute mandibular pain. His medical history included otic LCH and diabetes insipidus at age of 11 months. Intraorally, a pressure sensitive swelling, and radiographically, extensive bone loss were revealed on the area of lower second primary molars. The primary molars were extracted and histological examination confirmed the final diagnosis of HSC. The patient was treated with chemotherapy and the lesions decreased considerably. Two years later, a new swelling was recorded in the same area bilaterally. Biopsy confirmed recurrent HSC disease and the patient entered an alternative chemotherapy protocol. Six months later, improvement of the lesions was revealed. CONCLUSIONS: Dentists can contribute to a timely and valid identification of HSC disease by correctly differentially diagnosing lesions of head and neck.

PURPOSE: To evaluate the results of secondary osteoplasty in cleft patients, over a 12 years period, and to propose certain modifications and improvements of the cleft repair technique. MATERIALS AND METHODS: Data were retrieved for all young patients treated from 2000 to 2011. Patients were divided in 3 groups, of 4 years duration each; parameters registered among others included peri-operative orthodontics, type of graft used, techniques applied and revisions required until final repair. RESULTS: 65 patients (mean age 11.6 years) were included in the study. 80 cleft sites were treated. All clefts were finally repaired and bone continuity was achieved. Peri-operative orthodontics was applied in 84.6% of the cases. Bone grafts were harvested 60 times (84.5%) from the left anterior iliac crest and 11 times (15.5%) from the genial region of the mandible. During the 12 years period ameliorations and changes were made at the recipient site, regarding the technique applied and the type of the graft. Revision operations for additional bone grafting were required in 6 cases in all (6/80 or 7.5% of the cleft sites). A gradual reduction of the number of revision osteoplasties was recorded in the 3 time periods, attributed to the improvements afore mentioned. CONCLUSIONS: Cleft bone repair, even in difficult bilateral cases, may be achieved with standardised preparation of the recipient site, adequate graft from the iliac crest, used in the form of both particulate bone and cortical plate on top, as well as full coverage of the graft.
