Objective To explore the effect of follow-up nursing intervention on preventing dental plaque during oral fixed orthodontic appliance.Methods One hundred and twenty orthodontic patients receiving oral fixed orthodontic treatment were randomly divided into control and experiment groups equally according to visit time.The control group received conventional nursing during the process and follow-up nursing intervention during the process.The two groups were compared in terms of dental plaques before orthodontic, 3 and 6 months after the orthodontic treatment.Results Before the treatment, there was no significant differences in the dental plaques between them(P>0.05), but the indices of dental plagues in the experimental group were significantly lower than those of the control group 3 and 6 months after the orthodontic appliance(P<0.001).Conclusion Follow-up nursing care during orthodontic appliance are more effective for keeping oral hygiene.

Objective To study the diagnosis and prevention of gonococcus stomatitis. Methods 20 cases with gonococcus stomatitis were retrospectively investigated. Results There were mouth junction experience in 17 cases,sexual abuse experience in 10 cases,experience in association with patients with gonorrhea in 3 cases and the a-cute gonorrhea in 18 cases. The oral discharge smare and bacilliculture were carried out in 20 cases and the gonococ-cus stomatitis positive rate was 100 %. After sensitive antibiotic treatment, curing rate was 100 %. Conclusion The key to diagnose gonococcus depends on the integrity history and laboratory examinatoin,sensitive antibiotic treatment ensure clinical curing rate.

Implant restoration ; Provisional restoration ; Healing abutment ; Esthetic zone ; Esthetic outcomes: To compare the esthetic outcomes of peri-implant soft tissue conditioning with provisional restorations and healing abutments. Methods : A total of 48 patients missing a single tooth in the esthetic zone were chosen for the present study and divided into two groups. Twenty-six patients in Group A used provisional restorations to condition the peri-implant soft tissue before final restorations, while 22 patients in Group B used healing abutments to condition the soft tissue. All patients were evaluated by pink esthetic scores (PESs) at the time of the final restoration and at a 1-year follow-up. Results: A total of 26 implants in Group A and 22 implants in Group B showed good peri-implant soft tissue condition. PESs at the time of the final restoration and at the 1-year follow-up in Group A were 8.18 and 8.35, respectively, and 6.73 and 8.18 in Group B, respectively. PESs at the time of final restoration and at the 1-year follow-up were not significantly different in Group A but were significantly different in Group B. The PESs of the two groups were significantly different at the final restoration but were not significantly different at the 1-year follow-up. Conclusions Provisional restoration in the esthetic zone can improve the pink esthetic effect when permanent restoration.
