Subgingival Microbiota

Abstract Background: Periodontal pathology in children has distinctive characteristics that can be accounted for by the peculiarities of the age, the dynamically changing oral environment, and the processes of formation and stabilization of periodontal structures during teeth eruption. Aim: The aim of this study was to investigate the composition of the subgingival microbiota during permanent dentition formation in puberty. Materials and methods: The study included 30 children aged between 10 and 15 years without gingivitis (up to 25% PBI), with good oral hygiene, with no systemic diseases or reception of antibiotics for 3 months. The clinical status of all children was assessed using a specially designed chart based on the periodontal examination chart of a child adopted by the Department of Pediatric Dentistry, FDM-Sofia. Gingival sulcus samples were taken with a paper pin from 6 teeth for a PCR – Real Time study of 9 control strains (a comprehensive sample). The samples were sent for investigation in standardized containers. Results: C. gingivalis (green complex) was found in almost all tested children and F. nucleatum (orange complex) - in more than half of them. The rest of the tested samples for microorganisms was isolated in just few of the children (6% - 17%). A. actinomycetemcomitans and P. gingivalis were not isolated in this study. Conclusion: The results of the study suggest that a significant amount of the periodontal pathogens migrate to the subgingival zone relatively early, immediately after the permanent teeth eruption, and become a risk factor for the development of periodontal disease.

Relevance. Characteristics of eruption of secondary teeth is of diagnostic and prognostic interest, is the basis for implementation of targeted therapeutic and preventive measures among children. No research has ever been carried out in Uzbekistan to study an age and gender regional features of secondary teeth eruption. The aim is to determine the timing and symmetry of secondary teeth eruption in children of the city of Tashkent of the Republic of Uzbekistan and comparative assessment with the children of different cities of Russia.Materials and methods. 3,834 children between 3 and 17 years were conducted dental examination. A comparative analysis was made of the initial, intermediate and final periods of eruption of secondary teeth for children of Uzbekistan (Tashkent city) and Russia (Saratov, Izhevsk and Sergach).Results. In Tashkent children of both gender, in most cases, lower teeth were erupted before than their antagonists. In girls, teeth were erupted earlier than their male counterparts. At the initial stage of eruption, asymmetry was more pronounced in boys than in girls, while in the middle and final stages it was more pronounced in the opposite direction. Observed asymmetry of antimere’s teeth were indicated left-handed permanent dentition in boys and right-handed in girls. Children of Tashkent city were observed permanent dentition in one group of teeth 1-16 months earlier, and in others – 1-24 months later than their peers in Russian cities. Revealed differences were more pronounced among boys than among girls. Children in Tashkent differed more from their peers in Sergach and less from those in Izhevsk. Conclusions. Regional peculiarities of permanent dentition in children of Tashkent city and revealed expressed differences with indicators of Russian children are the basis for development of separate age and  gender normative assessment permanent dentition tables for children of Uzbekistan.

The purpose of this report is to present educational material that would allow the dental student to learn to easily identify the morphologic characteristics of permanent teeth, and how they fit together (occlusion). In order to do this, macro models of permanent teeth with no attrition were carved in wax and later molded with alginate. These molds were filled with plaster, dental stone and/or cold-cured acrylic resin. The large individual dental stone tooth models were mounted on a wax base, thus obtaining maxillary and mandibular arches which were occluded. These dental arches were molded with plaster or dental stone. The authors suggest that these types of macro models allow an excellent visualization of the morphologic characteristics of permanent teeth and occlusion. Dental students are able to carve the permanent dentition in wax with great facility when they can observe macro models.

The Relationship

Objective: Molar incisor hypomineralization (MIH), a quite common condition in pediatric dentistry, whose treatment might seem complicated, manifests itself with severe dental anxiety and fear that can cause behavioral problems. Although dental fear is seen in almost all cases, it is believed that dental fear will increase as the severity of MIH increases. This study evaluates the relationship between MIH severity and dental fear. Material and Methods: Children Fear Survey Schedule-Dental Subscale (CFSS-DS) was used to measure dental fear in 58 (51.79%) children whose teeth suffered from mild, moderate or severe MIH and 54 (48.21%) children with healthy teeth. Scores between 1 (not afraid at all) and 5 (very afraid) were given according to the responses. Each question was evaluated separately in order to obtain the total score. Results: Children with severe MIH who participated in the study were proved to be more afraid of the dentists, drill sounds, injections, placement of instruments in the mouth, choking and going to the hospital; and there was a statistically significant difference (p<0.05). Conclusion: Although it was observed that the severity of MIH and dental fear are correlated and dental fear increases with the increase in the MIH severity, further studies in this subject are necessary.

Abstract Background: Studies have reported a high prevalence of periodontal disease in individuals with intellectual disability (ID). The aim of this study was to compare the relative abundance of periodontal pathogens (red, orange, yellow, purple, and green complexes) between individuals with ID and healthy controls.Methods: Of the 31 subjects enrolled in this study, 16 with severe ID were selected from the outpatient clinic of the Special Care Dentistry of Hiroshima University Hospital, and 14 healthy subjects were selected from the outpatient clinic of another department at the same hospital. Dental plaque was sampled after oral examination. Decayed, missing, and filled permanent teeth (DMFT) counts were obtained and periodontal measurements were taken using the papillary-marginal-attached (PMA) index, plaque index (PI), gingival index (GI), and probing depth (PD). Gene sequencing (16S rRNA) was performed for each sample using next-generation high-throughput sequencing methods. The relative abundance of the periodontal pathogens and the clinical parameters were compared. An unpaired t-test was used to compare the oral health status in both groups and analysis of covariance was performed to compare the relative abundance of each pathogen.Results: No statistically significant difference in DMFT was observed between the two groups. However, significant differences in the median PMA index, PI, and GI were noted between the groups (P < 0.0001). In addition, the mean PD in the ID group was significantly higher than that in the control group (P < 0.0001). The relative abundances of Tannerella spp. and Treponema spp. were significantly higher in the ID group when compared to the control group at the genus level (P = 0.0383 and 0.0432, respectively); alternatively, the relative abundance of Porphyromonas spp. was significantly lower in the ID group (P < 0.0001).Conclusions: The PMA index, PI, GI, and PD were significantly lower in the ID group than in the control group. On the other hand, no significant difference in DMFT was observed between the two groups. Furthermore, our findings indicate that Tannerella forsythia might be more closely associated with periodontal disease than Porphyromonas gingivalis in individuals with ID.

The aim: To determine the structure of acute injuries of temporary and permanent frontal teeth in children, to analyze the applied diagnostic and treatment measures for acute tooth trauma and to investigate their effectiveness. Materials and methods: The subject of the study were 31 children aged 2-12 years with acute temporary and permanent tooth trauma. Methods: clinical (radiological, thermodiagnosis), medical and statistical. Results: The number of injured permanent teeth was greater than the number of injured temporary teeth. The pattern of temporary and permanent tooth injuries differed, so in temporary teeth dislocations were observed, and in permanent teeth fractures prevailed over dislocations. In our opinion, this is due to the peculiarities of the anatomy of the temporary teeth. Usually, the therapeutic tactics of acute temporary teeth injuries is to remove them, despite their important role in the growth and development of jaws, physiological formation and eruption of permanent teeth. The therapeutic tactics of dynamic observation in the case of intrusive dislocation of the temporary tooth were selected in the clinic of the Department of Pediatric Dentistry. In some cases, with a slight change in the position of the temporary tooth, self-regulation of its position was observed, in other cases the tooth remained dystopic, but its viability remained in 50% of cases. Therapeutic tactics of acute injuries of permanent teeth were selected according to the type of trauma. In the case of permanent tooth dislocation, with a slight change in its position, tooth immobilization was carried out by splinting with fiberglass tape and photopolymer composite material. Conclusions: Our observations have shown that the complex of modern specialized medical care for the affected children with acute traumatic injuries of the teeth should be guided by their preservation, which ensures the subsequent normal formation of the dental-jaw apparatus. To ensure these conditions, a long, reliable immobilization of the damaged tooth is required as soon as possible after injury.

Dentinogenesis Imperfecta type II (DI2), also known as hereditary opalescent dentin, is one of the most common genetic disorders affecting the structure of dentin, not related with osteogenesis imperfecta, which involves both primary and permanent dentitions. The purpose of this article is to perform a scoping review of the published peer-reviewed literature (1986–2017) on DI2 management in children and to outline the most relevant clinical findings extracted from this review. Forty four articles were included in the present scoping review. According to the extracted data, the following are the most important tasks to be performed in clinical pediatric dentistry: to re-establish the oral mastication, esthetics, and speech, and the development of vertical growth of alveolar bone and facial muscles; to reduce the tendency to develop caries, periapical lesions and pain; to preserve vitality, form, and size of the dentition; to avoid interfering with the eruption process of permanent teeth; to decrease the risk of tooth fractures and occlusion disturbances; to return the facial profile to a more normal appearance; and to prevent or treat possible temporomandibular joint problems. Therefore, Pediatric Dentists should bear in mind that early diagnosis and treatment, together a long-term follow-up of DI2 in children, continue to be the best approaches for achieving enhanced patient psychological well-being and, in consequence, their quality of life.

Background: The purpose of this study was to gather normative data on the mesio-distal crown dimensions amongst adolescent population of Province II, Nepal, to make an accurate diagnosis and treatment planning in orthodontics. It will also be useful in various clinical disciplines of dentistry including basic dental and anthropological research. Materials and Methods: Samples were selected Full form OPD of M B Kedia Dental College, Birgunj, Nepal. Total numbers of participants were 120, out of which 60 males and 60 females were selected after initial examination aged between 11 to 23 years. Subjects with all permanent teeth erupted (except second and third molar) without any history of previous orthodontic treatment and with no dental anomalies were included in this study. The alginate impressions were made by the well trained dental surgeon. Digital vernier calliper providing measurements to ± 0.01millimeter(mm) was used to measure the mesio-distal dimension of all teeth. Results: The mean, range and standard deviation were calculated for the size of the teeth. Independent t-test was used to compare between male and female population. The significance level was set at p value <= 0.05. The population of Province II, Nepal shows greater sexual dimorphism in mesio-distal crown dimension which was exhibited by the maxillary molars (0.88 mm) followed by mandibular molars (0.38 mm). Similarly in anterior tooth segment the maxillary canines (0.29 mm) followed by the mandibular canines (0.27 mm). Conclusion: The mean mesio-distal crown dimensions of the permanent dentition of males were larger than that of females for each type of tooth except maxillary central and lateral incisor.

ABSTRACTObjective: The aim of this study was to examine parental knowledge and attitudes about avulsed permanent teeth and their emergency treatment in children.Methods: A total of 289 parents of children aged 6-12 years receiving care at the Ondokuz Mayis University Pediatric Dentistry Clinic were included in the study. Questionnaires were used to collect data on parents’ demographic characteristics, previous training in traumatic dental injury and treatment and knowledge of avulsed permanent teeth and their emergency management. Chi-square tests were used to identify differences in responses for different variables.Results: More than half of the participating parents were female (69.6%) and between the age of 30-39 years (64.4%). Most (90.7%) reported that they would not replant the avulsed tooth in its socket, and most (68.2%) gave correct answers regarding the optimum time for which an avulsed tooth should be left out of the mouth prior to replantation. However, most parents were not sufficiently informed about the appropriate method for cleaning a dirty avulsed tooth or transporting it to a dentist or doctor. None of the demographic characteristics or training status was found to have a statistically significant effect on the number of correct responses regarding appropriate management of avulsion injuries (P>.05)Conclusion: This study revealed that the parental level of knowledge about the emergency treatment of avulsion in children is inadequate and that educational campaigns are necessary to improve proper emergency management of dental avulsion.
