The functional recovery of affected teeth by inducing root apiex formation using ultra-short wave

Background:The development of root of tooth lasted for 3～5 years after eruption.Pulpitis and apical periodontitis may contribute to the development stasis of root of tooth,and impair the masticatory function.In order to improve the development of root of tooth and root apiex formation ,the induced formation of cement in root of tooth by drugs was very important in clinic.Objective:To investigate the effect of ultra－short wave combined with antibiotics in the induction of root apiex and func…     

Endodontic management of the maxillary first molars with two root canals: A case report and review of the literature

BACKGROUND The complex anatomy of the maxillary first molars has always been a major challenge for complete root canal treatment in endodontic therapy. Here, we present two cases of maxillary first molars, each with only two root canals, which have been rarely reported. We also perform a literature review of maxillary first molar anatomy.CASE SUMMARY The two patients were referred to the hospital after 1) finding a cavity in their tooth with a color change and, 2) a toothache during mastication, respectively.Both of these cases were diagnosed as apical periodontitis by X-ray imaging and cone beam computed tomography(CBCT). Non-surgical endodontic therapy was performed with the assistance of a dental operating microscope(DOM). CBCT showed rare but accurate images of both patients, each with two root canals and two roots in their maxillary first molars. Both roots were located in the buccal in the palatal direction, and each root had only one clear root canal. In addition,each maxillary first molar in both patients was symmetrical to that on the opposing side with only two separate root canals. Non-surgical endodontic therapy was performed with the assistance of a DOM. Finally, the teeth were restored using composite resin and the patients were satisfied with the results.CONCLUSION Making full use of CBCT and DOM would contribute to helping dentists make correct diagnoses and successfully treat teeth with rare root canal morphologies.     

Microscopic removal of type Ⅲ dens invaginatus and preparation of apical barrier with mineral trioxide aggregate in a maxillary lateral incisor:A case report and review of literature

BACKGROUND Invaginated teeth pose greater challenges in clinical management because of their complex configuration.With advancements in equipment and materials,such as the dental operation microscope,cone-beam computed tomography and mineral trioxide aggregate,the preservation rate of type Ⅲ dens invaginatus could be greatly increased.CASE SUMMARY This case report presented a 31-year-old woman with complaints of spontaneous swelling and pain in the right maxillary lateral tooth.With the aid of cone-beam computed tomography,type Ⅲ dens invaginatus with apical periodontitis was diagnosed and confirmed.Three-visit endodontic treatment was performed.In the first visit,the invagination was carefully removed under the dental operation microscope,and chemomechanical preparation was done.In the second visit,mineral trioxide aggregate apical barrier surgery was performed in this tooth.In the third visit,the canal was finally obturated with thermoplastic gutta-percha to recover the crown morphology.A 26-mo follow-up revealed a satisfied outcome both in the radiographic and oral examinations.CONCLUSION In this case,removal of the entire abnormal structure provided great convenience for the follow-up treatment.When confronted with the same clinical case in the future,we can take a similar approach to address it.     

Effect evaluation of artemisia desertorum spreng on ability of daily life after extraction of impacted tooth

AIM：To investigate the effect of locally used Shahaosan on preventing the complication of extraction of impacted tooth.METHODS:274 cases patients with extraction of impacted teeth were randomly devided into 3 groups named A,B and C.Shahaosan and Yunnan white drug were grocessed into drug A and B by department of pharmacy with the same color,shape and quality which are blind to doctors and patients.When the impacted teeth were extracted,administed group A (92 cases) with drug A,group b(86 cases) with drug B and group c(96 cases) was a blank control.After the operation,incidence and severe intensity of dry socket in each group were observed and evaluated by scores.RESULTS:The incidence of dry socket in group a,B and C were 0.09%(1/92),2.32%(2/86),8.33%(8/96).There was no significant difference between group A and B,group b and C,while a significant difference showed between group A and C.The PoSSe score in group A,B and C was 19.36,27.80 and 22.83 respectively.Afer the experiment the department of pharmacy informed that drug A is Shahaosan and drug b is Yunnan white drug.CONCLUSTON:Compiments of dry socket induced by extracting of lower jaw impacted teeth can be prevented by locally administered with Shahaosan,but no significant effect of alleviating the symptom of dental extraction.     

Effectiveness of a microabrasion technique using 16% HCL with manual application on fluorotic teeth: A series of studies

BACKGROUND Dental fluorosis is caused by excessive fluoride ingestion during tooth formation.As a consequence,there is a higher porosity on the enamel surface,which causes an opaque look.AIM The aim of this study was to identify a dental intervention to improve the smile in patients with tooth fluorosis.Additional aims were to relate the stain size on fluorotic teeth with the effectiveness of stain removal,enamel loss and procedure time using a manual microabrasion technique with 16%hydrochloric acid(HCL).METHODS An experimental study was carried out on 84 fluorotic teeth in 57 adolescent patients,33 females and 24 males,with moderate to severe fluorosis.The means,standard deviations and percentages were analyzed using nonparametric statistics and ArchiCAD 15 software was used for the variables including stain size and effectiveness of stain removal.RESULTS The average enamel loss was 234μm and was significantly related to the procedure time categorized as 1-4 min and 4.01-6 min,resulting in a P>0.000.The microabrasion technique using 16%HCL was effective in 90.6%of patients and was applied manually on superficial stains in moderate and severe fluorosis.Procedure time was less than 6 min and enamel loss was within the acceptable range.CONCLUSION Microabrasion is a first-line treatment;however,the clinician should measure the average enamel loss to ensure that it is within the approximate range of 250μm in order to avoid restorative treatment.

烧伤后肠黏膜免疫组织细胞增殖分化的特征性研究

BACKGROUND: The descent of intestinal mucous membranous immune barrier will cause the translocation of opportunistic pathogen, which will lead to enterogenous infection that will affect the rehabilitation of patients‘ organisms and relevant functions, but the mechanism is still not well established.OBJECTIVE: To observe the transition of mIgA in peyer patch lymphocytes (PPL) and the conditions of proliferations in vitro of lamina properia lymphocytes(LPL) in intestinal mucous membranous immune tissues after burn,in order to increase mucous membranous immune barriers, to prevent enterogenous infections and to provide a clinical gist in speeding up rehabilitations in burn patients.DESIGN: A random control vertical study.SETTING and PARTICIPANTS; This study was completed in the Central Laboratory and Department of Burn Surgery, General Hospital of Chinese People‘s Armed Police Forces. Subjects were 20 SPF mice.INTERVENTION: The mice were randondy grouped into control group (n= 10) and burn group/n = 10). Mice in burn group were burnt with 20% of total body surface area(TBSA) in III degree burn and executed after 3-day of injury together with the mice in control group.MAIN OUTCOME MEASURE; IgA plasmoeytes in intestinal lamina propria(LP) were observed by in vivo imnmnohistochemical staining; IgA on the surface of lymphocytes in PP were counted by flow cytometry; in vitro proliferations of LP lymphocytes were assayed after burn; IL-6 in intestinal tissue was assayed b) ELISA.RESULTS: The positive rate of IgA in PP after 3-day of burn was lower than that of control group: the numbers of IgA ptasmocytes in LP after burn were significantly less than the level before burn, in vitro proliferation of the lymphocytes in LP was distinctly decreased after burn; the level of IL-6 in intestinal tissue had no significant difference compared with that of control group.CONCLUSION: Burn irffdbits the proliferation and differentiation of lymphocytes in intestinal mucous membranous immune tissues, which will lead to the depression of mucous membranous immune barrier.
