Patient- and clinician-reported outcomes for the additively manufactured sub-periosteal jaw implant (AMSJI) in the maxilla: a prospective multicentre one-year follow-up study.

The clinical outcomes of maxillary rehabilitation with the additively manufactured sub-periosteal jaw implant (AMSJI; CADskills BV) were evaluated in edentulous patients with a Cawood-Howell atrophy classification ≥5 in all regions of the maxilla. Fifteen consecutive patients were included in the study and followed up for 1 year. They were interviewed using a survey protocol and were examined clinically and radiographically preoperatively (T0) and at 1 (T1), 6 (T2), and 12 (T3) months after permanent upper prosthesis placement. The patients reported an increased oral health-related quality of life. The overall mean Oral Health Impact Profile-14 score at T0 was 17.20 (standard deviation (SD) 6.42). When results at T0 were compared to those at T1 (mean 8.93, SD 5.30), a statistically significant difference was seen (P = 0.001). At T3, the mean value was 5.80 (SD 4.18). Compared to T0, there was also a statistically significant difference at T3 (P = 0.001). General satisfaction based on the numerical rating scale was a mean 49.93 at T1, which was less than patient expectation prior to treatment at T0 (52.13). A higher overall value was seen at T3 (53.20) when compared to T0. Within the constraints of the short follow-up, the AMSJI appears to be a promising tool for patients with extreme jaw atrophy. The high patient expectations were met without complications.

Two radicular cysts associated with endodontically treated primary teeth: rationale for long-term follow-up.

Although radicular cysts are relatively rare, they do occur. In addition, it appears that these lesions present in association with endodontically treated primary teeth. As shown in this paper and previous reports, cysts can be associated with a variety of pulp therapies. These lesions can lead to bony expansion and resorption. Radicular cysts may also cause displacement and damage to the developing permanent dentition. Given the severity of these sequelae it is prudent to recommend regular radiographic examination of primary teeth that have undergone pulp therapy.

Risk factors for oropharyngeal candidiasis in patients who receive radiation therapy for malignant conditions of the head and neck.

Twenty-seven consecutive patients receiving radiation to the head and neck were followed to assess risk factors for the development of candidiasis. One-third of the patients developed oral candidiasis during radiation therapy. Xerostomia was shown to correlate with risk of oropharyngeal infection (p = 0.033). The presence and use of oral prostheses were shown to correlate with oral colonization of Candida albicans before radiation therapy (p = 0.011). Alcohol use and smoking represent risk factors for oral colonization by Candida during radiation therapy (p = 0.023 and p = 0.045 respectively). These factors must be assessed in future studies of oropharyngeal candidiasis in radiation therapy.
