Hermetic Seal

Abstract Pulp therapy helps in preserving a pulpally involved primary tooth by eliminating bacteria and their products and ensures hermetic seal of the root canals so that the primary tooth can complete its function without harming the successor or affecting the health of the patient. A thorough understanding of the pulp morphology and root formation and resorption in primary teeth as well as different materials and techniques used is imperative for a successful pulp therapy. One of the major areas of continued research is in the area of finding obturating materials to suit the specific properties of these teeth. This article seeks to present a review of the major obturating materials and techniques with their modifications as well as their advantages and disadvantages.

Objective: Knowledge of the microbial composition of deciduous endodontic infections is limited. This study aimed to evaluate the presence of the 10 oral bacterial species in samples from primary tooth root canals by using microarray technology and to determine the association of these organisms with clinical conditions. Study Design: The samples were collected from 30 root canals of primary teeth with primer infection. The bacterial composition of the samples was semi-quantitatively defined using a microarray system (Parocheck®). Results: All the tested species were detected in the samples. Fusobacterium nucleatum was the most frequently isolated bacterium (96.7%), followed by Prevotella intermedia (86.7%), Parvimonas micra (83.3%), Treponema denticola (76.7%) and Tannerella forsythia (66.7%). These bacteria were also present in high levels. All pairs of bacterial species were positively associated (RR≯1), except P.intermedia and P.micra. On average, five species (range:3-8) were detected per amplified sample. Root canals of teeth with ≯5 different species were statistically associated with periapical radiolucency (P=0.049). Conclusions: Primary teeth with endodontic infections show a highly diverse variety of bacteria, in which the most prevalent specie are present in high proportions. The well-directed use of the improved microarray technology will provide additional valuable information for causative factors associated with endodontic diseases, helping to develop more successful antibacterial or anti-inflammatory treatment strategies.

Choice Of Technique

Dental caries is a global concern affecting children and adults. A pulpectomy is considered to be the treatment of choice to preserve the pulpally involved primary teeth. Among the various factors determining the clinical success of pulpectomy, proper obturation of the root canals plays an important role. Different obturation materials are being used for the obturation of the primary teeth root canal, which includes zinc oxide eugenol, calcium hydroxide, calcium hydroxide iodoform paste and combinations. These materials are available in different forms such as powder, powder and liquid, paste forms. Various techniques are available to introduce the obturation materials into the root canal systems. These techniques have been tried to create a three-dimensional fluid-tight seal of the root canals. This review article aims to highlight the different techniques that are being used for the obturation of primary teeth. Each technique has its advantages and disadvantages. Creation of voids within the obturation, underfilling or overfilling are the common problems that can be encountered during root canal obturation. These factors can compromise the clinical and radiographic success of pulpectomy treatment. With the current evidence, no definitive conclusions can be made to decide which is the best obturation technique in terms of clinical and radiographic success. The choice of technique selection depends on the clinician’s preference, cost-effectiveness, time consumption, ease of handling.

Microbes are considered as the primary etiologic agents in endodontic diseases.Disinfection of the root canal is obtained by the combined effect of biomechanicalpreparation, irrigation and intra canal medicament. The aim of the present study wasto assess the antimicrobial activity of intracanal medicaments (formocresol andEndosepton) against two micro organisms (Streptococcus mutans and staphylococcusaureus) isolated from 15 necrotic pulps of primary molars indicated for pulpectomyprocedure. The samples were cultured, and purified using microbiological evaluation.Broth dilution test was performed in our study by preparing test tubes containing10 ml of BHI broth (pH. 7) which then inoculated with strains of the tested bacteriaand incubated at 37 C° for 24 h. After over night incubaction, ten fold dilution weremade in test tubes containing 9 ml of normal saline by adding 1 ml of the inoculum tothe first tube . Then from dilution 10-1 , 0.1 ml of cell suspension was added to 9.9 mlof formocresol and endosepton, then 0.1 ml was taken and spread on duplicates ofBHI agar plates at different intervals and incubated aerobically for 24 h. at 37 C°.Colonies on the plates were counted after incubation and CFU/mL (colony formingunit) was calculated. Our results indicating that there were no significant differencesbetween the intracanal medicaments, but there were high significant differencesbetween the intervals time of the study. We concluded that both materials had greatantibacterial effect against the pathogens commonly isolated from necrotic pulpaltissue of primary teeth.

Background: the main idea behind the pulpotomy of a primary tooth is to remove the infected or inflamed coronal pulp tissues and cover the pulp with a suitable medicament or dressing which promotes healing and preserve the vitality of the teeth especially in young permanent teeth. A medicament should be biologically compatible, have healing capabilities, should be non cytotoxic, or mutagenic and with no carcinogenic potential. Aim: the main aim of the study was to compare and evaluate the efficacy of commonly used two medicaments i.e. formocresol and sodium hypochlorite in pulpotomy of mandibular primary teeth. Material and methodology: a randomized controlled single blinded clinical trial was done on 50 subjects of age ranging from 3 to 6 years with bilateral mandibular first or second molar requiring pulpotomy. The subjects were randomly divided into two groups with 25 subjects in each. Group I, consisted of subjects on which formocresol medicament was used after extirpation of coronal pulp while in Group II, 3% sodium hypochlorite was used. Clinical along with the radiographic signs and symptoms were blindly recorded at an interval of 1, 3, 6 and 12 months respectively. Results: Statistically significant results were obtained in group II, when patients treated with 3% sodium hypochlorite. There was no major difference between the two medicaments used, but to the various adverse effects of formocresol, its usage has been limited. Conclusion: within the limitation of the study, it was concluded that sodium hypochlorite medicament proved to have better prognosis and can be suggested as a pulpotomy agent for primary teeth. Although formocresol was found to have similar significant results can also be used as a medicament. Keywords: Formocresol, Pulpotomy, Primary Teeth, Sodium Hypochlorite

Abstract BackgroundSurface roughness is one of the main factors affecting bacterial adhesion, biofilm growth, plaque formation and coloration on the tooth surface. Improper polishing may increase roughness or not contribute to a reduction in roughness while removing biofilms on tooth surfaces. The aim of this study is to examine the effects of different polishing pastes applied to the enamel of primary teeth on the surface roughness through AFM, which enables a more detailed examination of the measurements, and to evaluate the roughness changes created by the paste on the surface. MethodsIn the present study, in order to compare polishing made using Septodent Détartrine, Kerr Cleanic, Shofu Mersaage Regular under the recommendations of the companies in addition to the application of pumice with a rubber brush, a total of 88 samples with 22 samples in each group were created using 88 primary molar teeth. Before and after polishing, roughness measurements and visualizations were performed with atomic force microscopy (AFM). After polishing, Ra (average roughness) values, which express the surface roughness of the re-scanned samples, were calculated so that the samples were the same as the first scanning. For statistical analysis, Shapiro-Wilk normality test and generalized linear models tests were applied and p <0.05 was considered as statistically significantResultsIn the groups; while there was no significant difference in terms of roughness values ​​(Ra) within the group (p> 0.05), a statistically significant reduction in roughness (Ra) was observed on the sample surfaces after polishing in all groups compared to the baseline (p <0.05). According to the data obtained; all polishing methods used in the treatment of primary tooth discoloration can reduce the plaque formation and thus the amount of recoloring by reducing the surface roughness at a similar level.ConclusionAccordingly, it has been observed that the current polishing pastes do not provide a significant advantage over the traditional polishing method (polishing brush with pumice) in terms of surface roughness in removing discoloration in primary teeth.

Cementoblastoma is a rare benign neoplasm of odontogenic ectomesenchyme origin, involving the roots of any tooth, which occurs predominantly in second and third decade of life. Very few cases of cementoblastoma associated with a primary tooth or having a maxillary presentation have been reported in the past. Here, a rare case of a ten year old boy who presented to the department with a swelling in maxillary posterior region since one month is being discussed. The radiographic presentation was mimicking an odontoma. The final diagnosis was cementoblastoma. We have advocated the use of polarized microscopy to support the histopathological diagnosis with respect to its cemental origin. Cementoblastoma should be considered in the differential diagnosis of radio-opaque lesions in the transitional dentition.

AbstractThis study evaluated the structural and morphological differences between human and bovine primary root canals. Primary human maxillary central incisors (H) (n=9) and primary bovine incisors (B) (n=9) were selected. The roots were sectioned in the vestibular-lingual direction, planed and delimited in cervical, middle, and apical thirds. Tubule density (number of tubules per mm2) and diameter were analyzed by scanning electron microscopy (1,000 and 5,000×) using Image J 1.47 software. Data were submitted to two-way repeated measures ANOVA and Tukey tests (α=0.05). The highest tubule density was observed for B (28.527±1.717 mm2) compared with H (15.931±0.170 mm2) (p<0.01). Regarding root thirds, the cervical third presented a greater tubule density (26.417±11.654 mm2) than the apical third (17.999±5.873 mm2). The diameter of the dentin tubules was not different for cervical (3.50±0.08 µm), middle (3.45±0.30 µm) and apical thirds (3.42±0.33 µm) and substrate (H—3.29±0.14 µm; B—3.63±0.06 µm). It could be concluded that: (1) the radicular dentin structure of human and bovine primary teeth and root thirds differ in terms of the tubule density; (2) the radicular dentin morphology of human and bovine primary teeth and root thirds are similar in terms of the diameter of the dentin tubules.

Objectives: The aim of the present study was to assess the effect of calcium hydroxide as a root canal dressing material on dentin microtensile fracture strength in human primary teeth in vitro. Study design: Thirty primary anterior teeth with root canals packed with calcium hydroxide were divided into groups of ten and immersed in saline at room temperature for 7, 30 and 90 days. Ten teeth with root canals filled with sterile saline were the control group. Microtensile fracture strength was measured in Mechanical tester Lloyd testing machine. Results: There was a significant difference (P &lt; 0.05) between the fracture strength of the calcium hydroxide-filled teeth after 90 days (19.1 MPa) compared with the control (35.8 MPa). Dentin microtensile fracture strength of the calcium hydroxide-filled teeth decreased at an average of 0.142 MPa per day. Conclusion: Calcium hydroxide placed in root canals for an extended time had a significantly negative effect on root strength. Long-term success of root canal treatment in primary anterior teeth is estimated as 65% with most of the failures result from trauma recurrence. Clinical Relevance: Our results stress the need to evaluate the pros and cons of root canal treatment compared to extractions of non-vital primary incisors.
