Effectiveness of internet-based nursing interventions for the treatment of patients with periodontitis.

BACKGROUND: Periodontitis, one of the most common oral diseases, is a chronic inflammatory condition occur in response to bacterial plaque biofilms. Plaque control and oral hygiene instructions are the most widely used and effective nonsurgical treatment for periodontitis, which is based on a partnership between patient and clinician and requires a life-long commitment. The objective of this study was to analyze the effectiveness of internet-based nursing interventions for the treatment of patients with periodontitis. The findings from this study may help to enhance the therapeutic outcomes for patients with periodontitis. METHODS: A total of 80 patients with periodontitis treated in Zhejiang Province Stomatology hospital from December 2021 to January 2023 were randomly selected and divided into control group and intervention group with 40 cases each. The control group was given routine oral health guidance and the intervention group received internet based nursing intervention. The periodontal pocket depth, percentage of periodontal pocket depth (PD) ≥ 4 mm, bleeding on probing (BOP)%, and self-efficacy scale for oral health care (SESS) were assessed and compared at four time points: initial visit, 6-8-weeks follow-up, 3-months follow-up, and 6-months follow-up. RESULTS: There was no significant difference between the two groups in terms of age, gender, initial visit PD, initial visit PD ≥ 4 mm (%), initial visit BOP (%), and initial visit SESS (P > 0.05). The intervention group showed a significantly decreased percentage of PD ≥ 4 mm at 6-8 weeks and 6-months follow-up compared to the control group (P < 0.05). The PD, BOP%, and SESS scores of the intervention group were significantly better than those of the control group at 6-months follow-up (P < 0.05). There was no statistically significant difference in patient satisfaction between the two groups. CONCLUSIONS: This study confirmed that the internet-based nursing intervention in conjunction with periodontal treatment was able to improve the periodontal pocket depth, gingival bleeding and the level of self-efficacy of patients, suggesting that it is necessary to carry out the extended oral hygiene instructions via internet-based platforms for the patients in clinical practice.

[Repaired ulnar nerve and effect on its innervating muscles in rat].

OBJECTIVE: To study the morphological changes of the rat claw inner skeletal muscle after ulnar nerve injury at different sections and different recovery times. METHODS: Forty-two adult male Sprague-Dawley rats were selected and placed randomly in seven groups. After establishing model of injury and repair of claw inner skeletal muscle by cutting off the ulnar nerve, the muscle wet weight, cross section area of myocytes, and collagen fibers were measured. RESULTS: Claw inner skeletal muscle atrophy was significantly less in experiment groups compared with the control groups after ulnar nerve injuries. The functional recovery was better in the early repair groups than the late repair group. Collagen fibers increased slowly in earlier stage, but more significantly in late stage. The muscle atrophy was similar in wrist and elbow after ulnar nerve injury during the same recovery period. CONCLUSION: The function can recover completely or partly in early repair groups, but not quite effective in late stage. The increase of collagen fiber is one of the reasons to undermine the recovery effect of damaged ulnar nerve. There is no obvious difference of effect on the morphological changes of the rat claw inner skeletal muscle no matter the ulnar nerve is injured at wrist or elbow.
