There is a high incidence of chronic periapical periodontitis of deciduous teeth, however, there is a low incidence of the apical cyst. This paper reports a 7-year-old child with deciduous periodontitis caused by chronic periapical periodontitis of deciduous teeth. Through literature review, the etiology, imaging characteristics, diagnosis, differential diagnosis, and treatment methods were discussed to provide the basis for clinical diagnosis and treatment.

The essence of pulp and periapical disease is bacterial infection. Thus, satisfactory infection control is the premise and foundation of healing, in which root canal preparation is a critical procedure. Root canal system anatomy, infection degree, physical cutting during root canal preparation, and certain cleaning measures affect the quality of infection control. Appropriate evaluation of the grades of infected root canals before treatment is necessary because different grades of root canal infection demand various disinfection schedules to facilitate tissue healing and guarantee the long-term success rate of endodontic treatment.

To assess the treatment effectiveness of vital inflamed pulp therapy (VIPT) in immature permanent teeth with irreversible pulpitis and apical periodontitis. The faculty members in the Department of Pediatric Dentistry, the Ninth People's Hospital were invited to submit consecutive VIPT cases from June 2015 to June 2016 (follow-up periods>12 months). The cases were retrospectively reviewed, clinical symptoms and radiographic changes in periapical radiolucency were evaluated, meanwhile, the data of radiographic changes such as apical diameter and root length were calculated and analyzed with ANOVA. Totally thirteen submitted patients/cases were included (6 males and 7 females) in the present study,. The average age of patients was (9.9±1.4) years old. The average follow-up time was (26.5±6.8) months (17-37 months). At the 12-month visit, all 13 treated teeth survived, 9 out of 11 teeth with apical periodontitis showed normal radiographic manifestation. At the 3, 6 and 12 months visits, the within-case percentage changes in apical diameter were (8.0±5.1)%, (24.1±9.1)% and (70.3±10.7)%, respectively, while the within-case percentage changes in root length were (11.4±9.8)%, (14.5±9.8)% and (27.4±14.2)%, respectively. There were statistically significant differences in the changes of apical diameter (F=18.80, P<0.001) and root length (F=4.64, P=0.047) from the preoperative time to the postoperative follow-ups. VIPT might improve clinical outcomes, even achieve continued root development. VIPT can be an option in treating immature teeth with irreversible pulpitis and apical periodontitis.

OBJECTIVETo compare the therapeutic efficacy both apexification and revascularization in the immature anterior teeth of animal model with apical periodontitis, and observe the histological situation of revascularization in the root canal.
METHODSSix immature anterior teeth of one animal model (dog) aged approximately 4.5 months was selected. Afterwards, periapical periodontitis pattern were established, the samples were randomly divided into the experimental group (revascularization, 3 teeth) and the control group (apexification, 3 teeth). To compare the development of root and the healing of periapical inflammation, the involved teeth were respectively radiographed 1, 4, 8 weeks after surgery. The animals were sacrificed after 8 weeks, and the closure of apical foramen and the content of root canal were observed by hematine-eosine (HE) staining.
RESULTSThe postoperative radiography after 1 week and 4 weeks, the apical foramen size and the periapical radiolucency of the samples was shown no perceptual change. After 8 weeks, the experimental group periapical radiolucency area was obviously more narrowing, and had a apical closure tendency whereas the thickness of the root canal walls had imperceptible changed. While the control group periapical radiolucency change varied. The granulation tissue could be seen within the lumen of the experimental group, which contained a large number of irregular calcification, the calcification was obvious in the apical and adjacent the root canal wall. A small quantity of hard tissue was deposited in the apical of the control group.
CONCLUSIONRevascularization may increase the recovery of immature anterior teeth with chronic periapical inflammation, the vital regenerative tissue within root canal is the granulation tissue contained calcification.

Pulpitis and periapical periodontitis is a type of bacterial infectious disease, and bacteria frequently plant in the entire root canal system during the terminal stage. Main clinical treatment strategy of the disease requires root canal therapy, a key and core procedure for the successful treatment by thoroughly removing the root canal infection. The premise and guarantee of thoroughly removing root canal infection is by determining the accurate root canal working length. However, introduction of the complexity of the apical root anatomical structure, the confusion in determining the position of apical stop, and the method to determine the root canal working length. methods of accurately determining root canal working length, especially determining the position of apical stop, has been a hot topic among endodontic specialists, frequently causing confusion among many clinicians.
