The aim of the present prospective study was to evaluate periodontal health and subgingival microbiological alterations in adolescents treated with fixed self ligating orthodontic brackets in comparison to subject without any orthodontic appliance. A total of 40 adolescents (23 females and 17 males; mean age: 13.2 ± 3.2 years) were included: 30 subjects with self ligating brackets (test group) and 10 patients without orthodontic appliances (control group). Follow-ups were as follows: T1 (1 month), T2 (3 months), T3 (6 months) from the beginning of the orthodontic therapy. Clinical parameters (plaque index, gingival index and clinical attachment level) were measured for every patient and a microbiological analysis was performed. Mann Whitney test was performed to evaluate clinical parameters between test and control group and Friedman test and Fisher test were adopted to evaluate intra group differences at different follow-ups. Student T-test was performed to compare clinical attachment level between the two groups. Significance level was set at p0.05. No periodontal pathogens and no clinical attachment loss were found in the whole sample. A slightly higher plaque index and gingival inflammation were recorded in the test group in comparison to the controls.

It is well known that greenish pigmentation of the teeth is seen in children following remission of severe jaundice and clinical and serum bilirubin, a degradation product of haemoglobin, may be permanently trapped in forming dental hard tissues causing discolouration and enamel and dentine hypoplasia. Neonatal jaundice is the most common cause of hyperbilirubinemia and pigmentation of the deciduous teeth is the consequence of this condition. Various hepatobiliary pathologies may have a clinical finding in the oral cavity; furthermore, oral manifestations of hepatic pathologies are not just limited to the pigmentation of the deciduous teeth but also the permanent dentition and the mucous membranes can be affected.

Sjögren's Syndrome is a complex disease, due to an autoimmune physiopathology, that strongly impacts both patients' primary needs (nutrition and speaking), and patients' relationship life related factors (psychological health and quality of life). In Literature, few studies had investigated oral health status in Sjögren's syndrome and its impact on patients' quality of life, so the aim of this study was to analyse that issue. 30 patients were enrolled, within the Department of Rheumatology (University of Pisa), both first diagnosis patients' and both patients who had been diagnosed with Sjögren's syndrome in the past. For each patient, a medical record was filled out together with the compilation of the Oral Health Impact Profile questionnaire. Then, during a specialistic rheumatologic visit, Sjögren's Syndrome Disease Damage Index Score (SSDDI) was determined. Results showed a direct proportion between years from diagnosis and severity of oral health issues. It was found that these issues were related to soft tissue damage and an overall worse, reported quality of life and psychological health.

Cleft lip and/or palate patients (CLP) undergo corrective surgery that can affect facial growth. The aim of this study was to analyze facial growth and maxillary development of CLP subjects after surgery according to P.I.S.A. technique (Peri osteoplasty Improves Symmetry and Aesthetic). Cephalometric tracings of 55 patients were performed, thirty-three of which belonged to the test group, while the lasting twenty subjects were part of the control group. The test group was formed by cleft lip and/or palate patients after surgical repair according to P.I.S.A. technique. The control group included patients unaffected by this malformation, with an Angle's first class, selected from the Michigan Growth Study sample. Facial growth and upper maxilla development analysis was carried out by comparing the data obtained from the cephalometric traces of cleft patients who performed an early surgery, with the values of the same parameters measured in non-cleft subjects, providing the normal values. The results of this study showed, in the test group, a maxillary and mandibular bi-retrusion, a more negative facial convexity, the absence of a marked discrepancy in the skeletal relationships, a slight tendency towards hyper-divergence. .

Aim To evaluate the effect of audiovisual distraction on the dental chairside behaviour of children with Down syndrome (DS) during dental restorations and its influence on the operator stress and the duration of the appointment. Materials and Methods Study design: This randomised controlled trial included 48 children with DS requiring dental restorations. The study group was treated while wearing video eyeglasses, the control group with conventional behaviour management techniques. The child behaviour was evaluated using the revised Face, Leg, Activity, Cry, Consolability scale (r-FLACC) and the Frankl scale. The operator stress was evaluated using a VAS scale and the duration of the appointment was recorded. Results In the study group 64% of the children refused to wear the video eyeglasses during the whole duration of the dental treatment, the median r-FLACC score was significantly higher (p= 0.01552; Mann Whitney U test) and significantly more children showed a negative behaviour (68%vs 30%: p =0.011; Chi-square test). Conclusion Audiovisual distraction using video eyeglasses is not useful in managing the dental chairside behaviour of children with DS.

Molar incisor hypomineralization (MIH) is one of the most pressing issues in paediatric dentistry. It is a qualitative enamel defect of systemic origin that affects at least one first permanent molar and can also be associated with permanent incisors. However, the same defects have also been observed on primary molars and other permanent teeth. Hypomineralised enamel has less distinct prisms edges and crystals and the interprismatic space is more marked. Children with MIH undergo dental treatment nearly 10 times more than unaffected children. Preventive treatment following the diagnosis of MIH should take into account patient's age and collaboration, patient's caries risk, type and extension of demarcated lesions and hypersensitivity. Risk assessment and early diagnosis are key factors to an effective and conservative treatment.

This prospective clinical study evaluated the clinical performance of one-, two- and multi-surface composite resin inlays over a 12-year period on premolars and molars.One clinician placed 113 indirect composite resin inlays (Signum, Heraeus Kulzer) in 30 patients that were bonded using a three-step bonding system and composite resin luting cement. Evaluations were made at 3 and 12 years by another clinician who was not involved in the placement of the restorations, using the modified US Public Health Service (USPHS) criteria. Data were analyzed using a nonparametric statistical test (Mann-Whitney U test) followed by Bonferroni correction (alpha = .05).Fourteen patients could not be followed, yielding to the follow-up of 99 restorations. After 12 years, compared to the 3-year follow-up, tooth integrity, secondary caries, and sensitivity criteria showed significant change, while other parameters did not show significant difference (P.05). Parameters such as loss of marginal integrity, loss of restoration integrity, loss of surface polish, and secondary caries received more frequently delta scores. At the 3-year follow-up, the clinical performance of one- or two-surface inlays did not show significant difference from multi-surface ones (P = .6317), but at the 12-year follow-up, the results were more favorable for multi-surface inlays. Overall, the failure rate at 12 years was 12%.Adhesively bonded indirect composite resin inlays showed acceptable long-term clinical results in terms of function, but surface and margin characteristics changed over time.

Tooth development and mineralisation are processes that derive from different tissues interactions, in particular ectodermal and mesenchymal layers. These interactions are responsible for the formation of unique structures with a particular chemical composition. Despite differences, mineralised tissues are similar and they derive by highly concerted extracellular processes that involve matrix proteins, proteases, and mineral ion fluxes that collectively regulate the nucleation, growth and organisation of forming mineral crystals. This review aims at explaining mineralisation, its stages and when damage occurs and alters the hard tissues structure.

The purpose of this study was to evaluate the effects of type 1 diabetes and the possible role of metabolic control on the periodontal status of diabetic adolescents.Three groups of 40 patients each were examined: diabetic subjects with a good metabolic control (well controlled WC) (glycated haemoglobin HbA1c ≤ 7%) (20 males and 20 females; mean age: 14.1 ± 1.5 years); diabetic subjects with poor metabolic control (poorly controlled PC) (glycated haemoglobin HbA1c7%) (20 males and 20 females; mean age: 14.5 ± 1.3 years); and patients in good general health, which constituted the control group (20 males and 20 females; mean age: 14.1 ± 1.2 years). For each subject, a periodontal evaluation was performed and the following parameters were assessed: Plaque Index (PI), Gingival Index (GI), Bleeding on probing (BOP), Probing Depth (PD), Clinical Attachment Level (CAL). Chi-square was used to compare categorical variables. Kruskal-Wallis one-way ANOVA by ranks was used to compare the quantitative variables (GBI, PD) among the 3 groups. Post-hoc comparison between pairs of groups was assessed by Wilcoxon's rank sum test, with a downward adjustment of the alpha level to compensate for multiple comparisons.The levels of PI in WC subjects (1.9 ± 0.8) and in PC subjects (2.1 ± 0.6) were significantly higher compared to healthy subjects in the control group (0.8 ± 0.7) (p0.0001). Similarly, the GI in both PC (1.9 ± 0.8) and WC subjetcs (1.7 ± 0.9) was significantly higher (p0.05) compared to controls (0.9 ± 0.8). GBI in the PC (60.2 ± 23.6%) and the WC (57.4 ± 22.5%) groups was significantly higher compared to healthy subjects (35.9 ± 18.7%) (p0.05). The PD parameter was found significantly higher (p0.05) in the PC group (26.7 ± 12.6) and WC group (23.5 ± 11.3%) compared with controls (8.3 ± 6.2%). Regarding the CAL, no significant differences were found between the groups (p0.05). In addition, the comparisons between groups PC and WC were not statistically significant (p0.05).Adolescents affected with type 1 diabetes show a higher level of bacterial plaque, gingival inflammation with bleeding on probing and probing depth, compared to healthy subjects. There were no significant changes with regard to the accumulation of plaque and periodontal status among diabetic patients both with good control and with poor metabolic control.

The aim of the present investigation was to analyse cephalometric skeletal structures and hormonal and enzymatic parameters in young obese subjects in comparison with those of normal weight subjects.The whole sample consisted of 50 Caucasian patients (28 males and 22 females) whose lateral radiographs, laboratory hormonal and enzymatic analyses were already available. The test group included 25 obese patients (11 females and 14 males, average age: 9.8 +/- 2.11 years old), while the control group included 25 normal weight subjects matched for age and sex (11 females and 14 males, 9.9 +/- 2.5 years old). Data were statistically analysed: Student's t-test for independent samples was adopted and the level of significance was set at: p0.05.As regards cephalometric records, the anterior cranial base length was significantly greater in the test group (S-N: 69.9 +/- 4 mm) compared to the controls (S-N: 68.1 +/-2.7 mm). Moreover, the maxillary lenght was higher in the test group (Pm-A: 48.5 +/- 2.5 mm) in comparison to the control group (Pm-A: 46.1 +/- 1.9 mm). As regards skeletal class and vertical dimension, no significant differences were found between the two groups, with the exception of the intermaxillary plane angle, which was significantly lower in the obese subjects in comparison to the controls. Laboratory analysis showed significant (p0.05) higher levels of leptin and insulin in the test group in comparison with control subjects. Furthermore, LH, FSH, IGF-1 values were significantly (p0.05) lower in the test group in comparison with the control group.Obese subjects exhibited an increase of some craniofacial parameters and alteration of some laboratory parameters that may be involved in the process of skeletal maturation, in comparison to normal weight subjects. These findings may be of interest in orthodontics, as young obese subjects may need a different orthodontic treatment plan in comparison to normal weight subjects of the same age.

Abstract: Objectives: To determine the efficacy of 4 different oral hygiene regimens involving adjunctive interdental cleaning devices in unsupervised young subjects with intact interdental papilla. Material and methods: Sixty periodontally healthy subjects were randomly allocated to 4 groups following different oral hygiene regimens (T‐7): use of manual toothbrush alone; manual toothbrush plus dental floss; manual toothbrush plus interdental brushes; and manual toothbrush plus rubber interdental picks. Oral hygiene instructions (OHI) were given. One week after (T0), professional supragingival scaling and polishing was performed, and subjects were then reseen every 2 weeks (T14 and T28). At T‐7, T0, T14 and T28, full‐mouth plaque score (FMPS), full‐mouth bleeding score (FMBS) and angulated bleeding index (AngBI) were taken. Results: During the first week (T‐7/T0 unclean phase), FMPS decreased significantly in all groups except the group using dental floss. At T28, a significant decrease in FMPS (P < .001, all groups) and FMBS (P < .05, all groups except the group using flossing P < .001) was noted. Interdental FMPS showed significantly lower values in subjects treated with interdental brushes or rubber interdental picks vs toothbrushing alone (P < .05). The use of interdental picks was associated with reduced interdental FMBS when compared to flossing (P < .05). Conclusion: In young subjects, with no interdental attachment loss, toothbrushing or toothbrushing and adjunctive interdental cleaning devices such as dental floss, interdental brushes or interdental rubber picks can significantly reduce both plaque and gingival inflammation. Use of interdental brushes or rubber picks reduces more interdental plaque in comparison with toothbrushing alone. [ABSTRACT FROM AUTHOR]

Sjögren's syndrome (SS) represents a challenging illness to diagnose properly and, because of the serious complications such as lymphoma, it is important to reach a correct diagnosis in early stages. Aim of this retrospective study was to evaluate the correlation between histopathologic result of minor salivary gland biopsy and clinical and serologic parameters for the diagnosis of SS.We evaluated 360 biopsies, taken from the lower lip, of 360 patients (18 males) on suspicion that they were suffering from SS. The Chisolm and Mason classification was used to state the diagnosis of SS. For each patient, the medical history and the symptoms were evaluated, and diagnostic tests were performed. The revised rules of the American-European Consensus Group Criteria were used to diagnose primary and secondary SS. For the statistical analysis we used the Chi(2) test; a difference of P0.05 was considered significant.Considering the statistical correlation between a focal scoreor =1 and the serological data, it was noted that a positive score was significantly correlated to all serological parameters examined (P0.0001). A significant correlation was also found between a positive biopsy score and Schirmer's test and Rose Bengal test (P0.0001). However, with regard to the clinical data, a significant correlation was found only for two parameters: xerostomia (P0.0001) and parotid swelling (P0.05).Minor salivary gland biopsies are of great diagnostic value in detecting SS. However, for the diagnosis of SS both clinical and serologic parameters should be considered. The data obtained from the present survey reveal that the serologic markers are more predictive than clinical parameters for a positive biopsy score.

The aim of the study is to analyse the prevalence of anomalous function of the orofacial muscles and their aetiological factors in a small sample of paediatric patients, to evaluate the correlation between anomalous functions of the orofacial muscles and malocclusions, and finally to verify the effects of a myofunctional protocol, composed of a series of exercises aimed at correcting the anomalous function and position of the tongue.The protocol that has been used in this research is a re-elaboration of the diagnostic and therapeutic methods set by two authors, Daniel Garliner and Aurelio Levrini. A group of 57 children (aged 5 to 13, mean age 8.2) with atypical swallowing diagnosis, has been treated for almost 3 years.Physiologic swallowing was achieved in 47% of the children treated.The results show the benefits of the myofunctional therapy in the treatment of children with abnormal swallowing.

Platelet rich plasma (PRP) is utilized in oral surgery to enhance bone healing and it has been suggested to accelerate soft tissue healing. Nevertheless, there is no evidence on biological concentration of platelets needed to determine the higher biological response. Therefore, aim of this study is to evaluate the action of PRP in vitro on osteoblasts and fibroblasts and to evaluate which is the most effective concentration of PRP.PRP was obtained from volunteers donors by standard apheresis. Osteoblasts were growth for 72 hours in a medium added with platelet concentration of 230%. Fibroblasts were treated with different platelet density for 24 hours and 72 hours. Platelet density was increased of 230%, 350%, 460% and 700% the normal blood count. Cell proliferation was evaluated with MTT test. ANOVA test was used to assess cells proliferation data.Osteoblasts proliferation, at 72 hours, showed an increase of proliferation in PRP group compared to plasma (P0.001). Fibroblast proliferation after 24 hours increases when PRP is added (P0.05). However, no significant differences were detected among the various concentration of PRP. Yet, at 72 hours, MTT values increases when platelet concentrate is 230% and 350%. At 700% platelet density MTT values were lower than control group (P0.05).Our results indicated that PRP has an enhancing effect on osteoblasts and fibroblasts proliferation when it is prepared only within certain ranges of concentrations. However, further experimental studies are needed to confirm our hypothesis.

To provide diagnostic criteria for ankyloglossia in children by anatomical measurements; to investigate the correlation between severity of ankyloglossia and a series of morphofunctional findings; to evaluate the potential mismatch between a clinical suspect of ankyloglossia and the authentic anatomical diagnosis.Two different techniques of anatomical measurements and a clinical evaluation of a series of morphofunctional findings were performed.In 200 children referred for evaluation and treatment of tongue-tie, the length of the frenulum and the interincisal distance were measured in maximum opening of the mouth and with the tip of the tongue touching the palatal papilla. Occlusion, type of bite, tongue resting position, swallowing mechanism, oral floor mobility, frenulum insertion modality and speech were investigated. Any correlation between these morphofunctional findings and anatomical measures was investigated.Children with a frenulum length more than 2 cm and an interincisal distance of more than 2.3 cm were normal. In both measurements, significant correlations among mean values and other variables were observed. Moreover, three levels -- mild, moderate and severe -- of ankyloglossia were assessed.Length of frenulum and interincisal distance allow an assessment of severity of ankyloglossia in children. Ankyloglossia was not associated with infantile swallowing.

Hypo-estrogenism during menopause is the cause of numerous disturbances affecting various structures such as the oral cavity which can present with the following symptoms: changes in salivary secretion, gingivitis, bleeding and altered taste sensation. The object is to study whether hormone replacement therapy prescribed for female patients in menopause have any beneficial effect on the oral discomfort which affects the quality of life of these patients.The study enrolled 95 female patients; 14 were the control group and received no hormone replacement therapy while 81 patients underwent two types of therapy: 38 were prescribed estrogen therapy and 43 phytotherapy. The main outcome measures were alterations of the oral cavity: salivary change, gingivitis, bleeding and taste changes.It was observed that the patients receiving treatment had an improvement or disappearance of symptoms in the oral cavity and that estrogen was more effective than phytotherapy regarding the salivary change while the gingivitis, bleeding and taste changes was the same for both therapies.Estrogen and phytotherapy have beneficial effect on oral discomfort in women in menopause. The proposed treatment can have a beneficial effect on osteopenia and osteoporosis and therefore also on possible increase of future tooth loss during menopause.

The aim of this study was to evaluate the shape and the average size of the maxillary and mandibular arch in an Italian adolescents' sample with correct occlusion, using the digital technology. The study sample was composed, after the use of an extra-oral scanner and after the application of inclusion and exclusion criteria, by the digitized dental casts of 79 Italian adolescents (39 females and 40 males), aged 14±1 years, with correct occlusion. On each model, both upper and lower, the reference points of the dental arches (FA), of the alveolar bone (WALA ridges) and of the incisal edge of the central incisors were identified. With these points, using a software, fourteen parameters were evaluated for each cast: basal and dental intermolar and inter-canine width, basal and dental molar and canine depth, basal and dental molar and canine ratio, overjet, overbite. Finally, the shape of the arches was assessed, dividing it into ovoid, triangular or square. Chi-square test and Student's T-test for each parameter were adopted with a p0,05 significance level. The results showed that the ovoid form was the most frequent, followed by the triangular one for the upper arch and by the rectangular one for the lower arch. On the canine level, both upper and lower, both for dental and for basal references, the triangular shape showed the lowest width and ratio values and the highest depth values in comparison with the other two groups. The square one showed the opposite situation, and the ovoid one presented in the intermediate value. On the molar level the trend is quite similar to the canine one. The results obtained maybe suggest that on a significant percentage of the patients of the sample is expected to use a preformed ovoid arch wire, and the data found could be useful to study the adequacy of the arch wires currently on the market or to design new ones. .

Assess prevalence, familial predisposition and susceptibility to caries of Black Stains (BS). Evaluate the microbiological composition of BS, saliva and subgingival plaque.Sixty nine subjects with BS (test group) and 120 subjects without BS (control group) were analysed for oral status. For each BS-patient, a BS-deposit, 1 ml of saliva and subgingival plaque were collected and microbiologically analysed. Five deciduous teeth with BS were observed under SEM.This study showed a BS prevalence similar to that of the Mediterranean area and a familiality. The microbiological origin of BS was confirmed by SEM and culture method and the BS flora differ from that of supragingival plaque.Predominance in BS and saliva of Actinomycetes and the low salivary prevalence of S. mutans and L. acidophilus may be related with low caries incidence in BS patients. The high presence of Actinomyces spp can be a causative factor for BS.

Cigarette smoke contains oxidants such as oxygen-free radicals and volatile aldehydes, which are probably the major causes of damage to biomolecules exposed to cigarette smoke. However, saliva has an antioxidant defense system able to counter toxic activities of radical species that is formed by antioxidant enzymes, including superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). The purpose of this study is to verify the possible effects of cigarette smoke on SOD and GSH-Px. Forty-four patients (25 males and 19 females) were enrolled in this study. The participants were 20 smokers (12 males and 8 females) and 24 non-smokers (13 males and 11 females). Furthermore, 10 subjects of the control group were ex-smokers (9 males and 1 female). Their mean age plus or minus standard deviation (SD) was 58.8 plus or minus 15.9 years for the case group and 73.8 plus or minus 10.6 years for the control group. All patients were underwent a careful anamnestic investigation and examination of the oral cavity. After rinsing the mouth with water, each subject put 3 cc of non-stimulated saliva inside a test tube. The saliva was centrifuged and oral peroxidase and superoxide dismutase activity was measured according to a specific assay. Statistical analysis was performed to evaluate differences between the groups and significant differences were observed for p less than 0.05. A significant decrease of GSH-Px activity was detected in the smoking group (p less than 0.05), while the SOD activity was similar in the control and case groups. According to the sex, a significant decrease of GSH-Px activity was noted in males of the smoker group (p less than 0.05), while in the sample of females no significant difference of the enzymatic activity was found. Moreover, among ex-smokers, there was a significant difference in the values of GSH-Px between those who had not smoked for less than ten years and those who had not smoked for more than ten years. Cigarette smoke may alter the detoxification of hydrogen peroxide through a decrease of GSH-Px activity. The overproduction of H2O2 may lead to an oxidative stress that is involved in a large number of diseases, including precancerous and neoplastic lesions of the oral cavity. The effects of cigarette smoke on salivary antioxidant enzymes decrease after withdrawal from smoking and the benefits become more evident with the passage of time.

- Abstract
Aim: X-linked hypophosphatemic rickets (XLH) is characterised by severe skeletal deformities and dental abnormalities. The aim of this work is to examine the prevalence of abscesses, the features of pulp chambers, and the biochemical and histological signs of the disease., Methods: Pulp chambers size, shape, and morphology were assessed by orthopantomography in XLH patients (n = 24, age 5.8 ± 1.6 years) and in sex and age-matched healthy controls (n = 23, age 6.2 ± 1.4 years). Histological analysis of the dentin of the primary teeth by Hematoxylin-eosin and Massontrichromic Goldner-blue aniline staining was then performed, comparing the results with those obtained in healthy controls., Conclusion: Enlarged pulpal chambers with altered shape and morphology affect most XLH patients, setting them up for periapical abscesses with fistulas occurred without any history of trauma or dental decay. Patients with XLH should be considered high-risk patients. It is important to treat and manage them early by a multidisciplinary approach.

- Abstract
Rare diseases are an often an overlooked public health problem. Although they are infrequent, occurring on average in 100-500 people per million, these diseases represent a significant challenge in paediatric dentistry due to their complex manifestations and the need for specialised care. Conditions such as X-linked hypophosphatemic rickets (XLH), hypophosphatasia (HPP), and osteogenesis imperfecta (OI) exemplify the intersection of systemic health issues and oral health, requiring a multidisciplinary approach for their effective management. Dentists frequently play a crucial role in identifying genetic alterations through their dental manifestations and then referring patients to the geneticist for a definitive diagnosis. X-linked hypophosphatemia is the most common genetic form of rickets, with a prevalence of 1/20,000 - 1/60,000. XLH is characterised by stunted growth with disproportionate short stature, bowing of the lower limbs associated with reduced motor skills, osteoarticular pain, hypotonia, and dental and periodontal anomalies. XLH is due to inactivating mutations in the PHEX gene which cause excessive production of fibroblast growth factor 23 (FGF23). Increased concentration of FGF23 represents the main pathogenetic mechanism of XLH, stimulating urinary phosphate loss and renal 24-hydroxylase activity, and reducing renal 1α-hydroxylase activity with insufficient production of 1,25 -dihydroxy-vitamin D (1,25(OH)2D). PHEX protein is also expressed in osteoblasts, osteocytes, and odontoblasts. Regardless of FGF23's systemic effects on phosphate homeostasis, odontoblast differentiation, and dentin formation, its overexpression directly reduces osteoblast differentiation and matrix mineralisation. In patients with XLH, the deficit of 1,25(OH)2D induced by FGF23 causes poor enamel mineralisation with presence of cracks on teeth surface. XLH patients have recurrent dental abscesses with fistulas. Radiographic investigations highlight a generalised enlargement of the pulp chambers, molars with short roots, and a taurodontic appearance. Hypophosphatasia (HPP) is another condition in which dental manifestations precede systemic symptoms; it is a rare genetic disease (1/300,000 for severe forms, 1/100,000 for moderate forms. The incidence is perhaps underestimated due to missed diagnosis of moderate forms of the disease). It mainly affects bone and dental mineralisation. It is caused by pathogenic variant mutations in the ALPL gene which is located on the short arm of chromosome 1 and encodes the non-tissue-specific alkaline phosphatase (TNSALP) enzyme. TNSALP deficiency results in vitamin B6 (pyridoxine) deficiency and pathological accumulation of alkaline phosphatase substrates which may be responsible for extra-osseous manifestations, such as neurologic ones (pyridoxine sensitive seizures) as well as involvement of muscles and joints (arthropathies, muscle fatigue/hypotonia). Early non-traumatic loss of primary teeth between the ages of 2 and 4 years (and sometimes earlier) with an intact, non-resorbed root is a sign of disease. Tooth mobility precedes exfoliation of the tooth/teeth, most often without associated gum inflammation or pain. The primary incisors are the most affected teeth, and the number and type of primary teeth lost are proportional to the severity of the disease. From a radiologic perspective, characteristic signs include localised or generalised horizontal alveolar bone loss, large pulp chambers, intrapulpal calcifications, and reduced enamel thickness. Osteogenesis imperfecta, or brittle bone disease, is a rare condition characterised by bone fragility and osteopenia. It combines skeletal signs of varying severity (mainly fractures, hyperlaxity, and ligament deformities) and extra skeletal signs (bluish sclera, deafness, vascular fragility). It may also involve dentinogenesis imperfecta. The severity of clinical manifestations is highly variable, ranging from moderate forms that can go unnoticed to major forms that are lethal in the perinatal period. The birth prevalence of osteogenesis imperfecta is approximately 1 in 10,000 people. In approximately 90% of cases, it is an autosomal dominant disease due to monoallelic mutations in the COL1A1, COL1A2 or IFITM5 genes. Ten percent of cases are recessive forms characterised by dentinogenesis imperfecta, where the dental manifestations include teeth discoloration and weakness. The timely recognition of dental manifestations of these rare genetic diseases can allow providers to make an early diagnosis even prior to the development of systemic complications, and for this reason paediatric dentists have a key role in the recognition and management of these patients. Once the diagnosis is suspected, the dentist should refer patients for a genetic evaluation so as to ensure multidisciplinary management and initiation of medical therapies with the collaboration of paediatricians, endocrinologists and other health specialists. The role of dental professionals is not limited to the diagnosis of these rare diseases, but it also encompasses delivering specific, patient-tailored treatments, encouraging preventive care with regular dental visits and educating patients with the ultimate goal to promote not only oral health but the patient's overall wellbeing.

- Abstract
Aim: Periapical cysts of primary teeth are pathologic entities which are seldom encountered in the clinical practice. Most frequently, these lesions arise in correspondence with primary teeth presenting previous pulp therapy, severe carious lesions, or a history of previous trauma. The aim of the present study is to systematically review the treatment modalities of periapical cysts of the deciduous, along with the reporting of a clinical case., Materials: A case of periapical cyst treated with marsupialization occurring in an 11-year-old patient is described. A literature search was devised to retrieve studies reporting the treatment of periapical cysts, and involved papers published in the Cochrane Oral Health Group specialist trials, MEDLINE via PubMed, and EMBASE up to March 2023. A total of 39 articles were retrieved. Following title and abstract analysis, 27 articles were selected for full-text analysis, with the final inclusion of 24 articles., Conclusion: Periapical cysts of primary teeth present an overall good prognosis irrespective of the treatment option adopted. The performance of a prompt diagnosis appears of utmost importance, as the extraction of the primary teeth involved implies the management of the residual space for the correct positioning of the corresponding permanent teeth.

- Abstract
It is well known that greenish pigmentation of the teeth is seen in children following remission of severe jaundice and clinical and serum bilirubin, a degradation product of haemoglobin, may be permanently trapped in forming dental hard tissues causing discolouration and enamel and dentine hypoplasia. Neonatal jaundice is the most common cause of hyperbilirubinemia and pigmentation of the deciduous teeth is the consequence of this condition. Various hepatobiliary pathologies may have a clinical finding in the oral cavity; furthermore, oral manifestations of hepatic pathologies are not just limited to the pigmentation of the deciduous teeth but also the permanent dentition and the mucous membranes can be affected., (Copyright 2020 Biolife Sas. www.biolifesas.org.)
