Hypophosphatasia (HPP) is a rare genetic disorder; affected patients may experience early exfoliation of primary teeth, especially anterior teeth. However, there have been few reports regarding longitudinal follow-up for primary teeth, especially posterior teeth, until their replacement with permanent teeth. Here, we describe a patient with HPP who underwent follow-up from 1 to 9 years of age. A 14-month-old boy was referred to our hospital with the chief complaint of early loss of primary anterior teeth. He was diagnosed with odonto-type HPP by his pediatrician, due to low serum alkaline phosphatase concentration and early exfoliation of primary teeth with bone hypomineralization. The patient experienced exfoliation of three additional primary anterior teeth by 4 years and 1 month of age. Partial dentures were applied for space maintenance; there were no problems regarding subsequent replacement with permanent teeth in the anterior region. However, the primary mandibular right first molar appeared to be submerged when the patient was 8 years and 3 months of age; the severity of submergence was greater when the patient was 9 years of age. The affected primary molar was considered to be ankylosed; it was extracted when the patient was 9 years and 4 months of age. Histopathological analysis of the tooth revealed disturbed cementum formation, which is a typical characteristic of teeth in patients with HPP. On the basis of these findings, we hypothesize that the disturbed cementum formation could lead to susceptibility to early exfoliation of anterior teeth, as well as occurrence of ankylosis involving posterior teeth.

Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.

Background and Objectives: Primary teeth and the integrity of the primary teeth are very important for the normal growth and progress of the occlusal relationships and the dentofacial structures. Premature loss of the primary teeth may lead to the loss of the arch length needed for the eruption of permanent teeth and thus lead to rotation, crowding, and impaction of permanent teeth. This study aimed to determine the prevalence of premature loss of primary teeth among children aged 6-10 years in Sana'a city, Yemen. Materials and methods: This observational cross-sectional study included 1091 children, aged 6-10 years. An experienced examiner the first author carried out all clinical examinations under natural light. Data were collected including age and missing teeth. Results: The results showed that 26% of the sample suffered premature loss of primary teeth with no significant difference between the sexes (P> 0.05). There was low  in prevalence of premature loss of primary teeth in 10 years (17.7%), while the rate raised to 29.7%, 31.6%, and 31.7% in 6,7 and 9 years respectively. When considering the number of teeth, the prevalence of one premature loss was 10.8%, followed by two premature losses (9.8%), while the loss rate of 3 or more was5.4%. Considering dental arch 61.8% of loss was Mandible loss, while the loss in Maxilla was 38.1% only. The most common missing tooth is the first lower right primary molar (17%). Conclusion: The prevalence of premature loss in our study is similar to that of developing countries, the rate was low at 10 years for children, while the rate increased at 6,7 and 9 years; most of the loss was in the lower jaw and the most common missing tooth was the right lower primary molar. This result determines the importance of increasing awareness of this problem and focusing on the need for more preventive efforts to maintain healthy and natural teeth that improve the chewing function and aesthetic appearance of children and the entire population.

The Moment

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

Objectives: Biopure MTAD™, a new root canal irrigant has shown promising results against the most common resistant microorganism, E. faecalis, in permanent teeth. However, there is lack of studies comparing its antimicrobial effectiveness with NaOCl in primary teeth. The purpose of this study was to compare the in vivo antimicrobial efficacy of NaOCl 2.5% and Biopure MTAD™ against E. faecalis in primary teeth. Study design: Forty non vital single rooted primary maxillary anterior teeth of children aged 4-8 years, were irrigated either with NaOCl 2.5% (n=15), Biopure MTAD™ (n=15) and 0.9% Saline (n=10, control group). Paper point samples were collected at baseline (S1) and after chemomechanical preparation (S2) during the pulpectomy procedure. The presence of E. faecalis in S1 & S2 was evaluated using Real time Polymerase Chain Reaction. Results: Statistical significant difference was found in the antimicrobial efficacy of NaOCl 2.5 % and BioPure MTAD™ when compared to saline (p&gt;0.05). However, no statistical significant difference was found between the efficacies of both the irrigants. Conclusions: NaOCl 2.5% and BioPure MTAD™, both irrigants are equally efficient against E. faecalis in necrotic primary anterior teeth. MTAD is a promising irrigant, however clinical studies are required to establish it as ideal root canal irrigant in clinical practice.

The Impact

Background: An injury to both the primary and permanent teeth and the supporting structures is one of the most common dental problems seen in children. Splinting is usually difficult or impossible to perform in the primary dentition (due to diminutive room size and lack of patient cooperation). Healing must, therefore, occur despite mobility at the fracture line, usually resulting in interposition of connective tissue. In some instances, infection will occur in the coronal pulp. The present study reported a case of trauma to the anterior primary teeth and alveolar bone in a four year old child. The trauma has caused fracture to the crowns and roots of the primary anterior teeth. The following case was managed in a procedure that may provide primary teeth subjected to trauma a better chance than extraction with a better prognosis. Case presentation: a 4 and a half year old child was subjected to trauma in anterior segment of maxilla. Suturing of the torn soft tissue was the first step followed by pulpotomy for the left primary lateral incisor. Fixation of the right primary central and lateral incisors was done by acid etch wire fixation. Both clinical and radiographic follow up was carried out for 6.4 years. Results: healing of the soft tissue was observed after one week and completed after two months. Fixation of the teeth continued for ten months. The fracture lines in the roots remained in position. Clinically there was no sign of any pulpal inflammation or necrosis. Radiographically, no signs of infection to the surrounding tissues could be seen, no resorption in the alveolar bone, external or internal resorption of the root did not happen also. After ten months fixation ended and the wire was removed. At that time there was normal resorption of the roots of the primary incisors in relation with the normal development of the permanent incisors. After 3 years both permanent central incisors erupted in their normal position. After 6.4 years all four permanent incisors erupted into occlusion in their normal position. Conclusion: primary teeth with root fractures and severely mobile coronal fragments can be treated by a conservative approach. The severity of the sequels is directly related to the degree of permanent tooth formation (child’s age), type of dental trauma and extent of the impact. Key words: trauma, primary incisors, fractured crown and root

Full Mouth Rehabilitation

Dentinogenesis imperfecta (DI) is a genetic disorder affecting the structural integrity of the dentin that can result in weakened dentin. The affected teeth, especially posterior teeth, often need to be extracted due to severe wear or fracture. This frequently yields a loss of posterior occlusion and occlusal vertical dimension. Besides wear and fracture, anterior teeth often have an unesthetic appearance because of discoloration. Current treatments of choice, including composite bonding restorations and, more recently, all-ceramic restorations, are typically suggested to preserve the remaining teeth and tooth structure. However, there are a limited number of studies on dental implants in patients with DI. The effectiveness of dentin bonding and dental implants in patients with DI is not known. This clinical report describes a 32-year-old Asian woman with DI who underwent full-mouth rehabilitation. The posterior occlusion, mostly in the molar areas, was restored with dental implants and ceramometal restorations. The anterior teeth and premolars were restored with bonded lithium disilicate glass-ceramic pressed veneers and crowns made with computer-aided design/computer-aided manufacturing. This case demonstrates that restoring functional occlusion and esthetics for a patient with DI can be completed successfully using contemporary implant therapy and adhesive dentistry.

SUMMARY Tooth wear is a multifactorial condition of growing concern. In clinical practice, it is often a challenge for prevention and treatment since many etiological factors may be involved. This case report describes an esthetic rehabilitation of a young patient presenting tooth wear due to erosion. The etiological factor of this case was the patient sucking on lemons, an acidic fruit. The main complaint of the patient was the appearance of short maxillary incisors. The treatment involved orthodontic and restorative dentistry techniques. First of all, an orthodontic device was used to increase the vertical dimension of occlusion and create an adequate space for the direct restorations. The posterior teeth were restored with two direct composite resin techniques; the anterior teeth were then restored using a balanced occlusion. The seven-year follow-up of the case is presented. Replicas of the restorations were made and visualized under scanning electron microscopy up to the 12-month evaluation. In the clinical follow-up at seven years, maintenance of the results and restorations can be clearly seen.

Developmental Defects Of Enamel

The risk of dental caries seems to be greater in the presence of developmental defects of enamel (DDE). The aim was to determine whether the presence of DDE in the primary teeth of preschool children increases the risk of dental caries in the primary dentition after a period of approximately 2 years. This study was conducted in two stages: baseline (T0) and follow-up (T1). At T0, examinations were conducted for the diagnosis of enamel defects using the DDE index (FDI, 1992), dental caries, and oral hygiene. The participants were allocated to two groups according to the presence (affected) or absence (unaffected) of DDE. At the second evaluation (T1), examinations were performed for the diagnosis of dental caries. Poisson regression analysis with a multilevel approach was used to determine the association between DDE and dental caries. The two levels of the analysis were tooth and child. Among the 339 children (113 affected and 226 unaffected) examined at baseline (T0), 325 were re-examined at follow-up (T1). According to the multilevel analysis, teeth with enamel hypoplasia had a greater risk of having dental caries (RR: 1.99; 95% CI: 1.19–3.33). The risk of caries was greater on posterior teeth (RR: 2.59; 95% CI: 2.18–3.07) and maxillary teeth (RR: 1.48; 95% CI: 1.26–1.75) that had DDE at T0. On the child level, dental caries at T1 was associated with having dental caries at T0 (RR: 1.38; 95% CI: 1.32–1.46). In conclusion, enamel hypoplasia and previous dental caries are risk factors for carious lesions in the primary dentition.

Destructive forms of periodontal disease in children are uncommon. Severe periodontal destruction can be a manifestation of a systemic disease; however, in some patients, the underlying cause of increased susceptibility and early onset is still unknown. Objective: To describe an effective therapeutic approach to Generalized Aggressive Periodontitis (GAgP) in children, based on a 3-1/2 year-old male patient referred to the Hospital due to early loss of incisors, gingivitis,and tooth mobility in his primary dentition. Intraoral examination revealed severe gingival inflammation,dental abscesses, pathological tooth mobility, bleeding upon probing and attachment loss around several primary teeth. Dental radiographs revealed horizontal and vertical bone loss. Treatment consisted on the extraction of severely affected primary teeth, systemic antibiotics, deep scaling of remaining teeth and strict oral hygiene measures. Once the patient's periodontal condition was stabilized, function and esthetics were restored with "pedi-partials." After a follow-up period of nearly 4 years, the patient's periodontal status remains healthy, facilitating the eruption of permanent teeth. Conclusion: Prompt diagnosis and good treatment regimen may provide an effective therapeutic management of Generalized Aggressive Periodontitis.
