Abstract

:The current American Association of Endodontists clinical considerations for a regenerative endodontic procedure state that a regenerative procedure is suitable for immature permanent teeth with necrotic pulp when the pulp space is not needed for a post/core in the final restoration. Therefore, many immature permanent teeth with necrotic pulp that have sustained a substantial loss of coronal tooth structure either from caries or trauma are treated by apexification or mineral trioxide aggregate/Biodentine (Septodent, Lancaster, PA) apical barrier techniques in which no further root maturation would occur. This case series presents 10 immature permanent teeth with necrotic pulp in which a post/core was likely required in the future for adequate coronal restoration because of loss of substantial coronal tooth structure and a modified apexification procedure was used. All 10 cases after the modified apexification procedure showed no clinical symptoms/signs and showed radiographic evidence of healed/healing of periapical lesion after a 2-year review. Eight cases showed increased thickness of the apical root canal walls, increased apical root length, and apical closure. The overall percentage change in root length was 7.52%, in root width at the apical one third it was 18.89%, and in radiographic root area it was 15.04% at the 24- to 72-month follow-up period. This modified apexification procedure allows for the tooth to be restored with a post/core if required for the final restoration in the future as well as continued root development.

摘要

: 目前美国牙髓病医师协会对再生牙髓手术的临床考虑指出,当牙髓间隙不需要后/核时,再生手术适用于牙髓坏死的未成熟恒牙。最后的恢复。因此,许多坏死牙髓的未成熟恒牙由于龋齿或外伤而持续大量丧失冠状牙结构,可通过根尖成形术或三氧化矿物聚集体/生物牙本质 (Septodent,Lancaster,PA) 根尖屏障技术,其中不会发生进一步的根成熟。本病例系列介绍了 10 颗伴有坏死牙髓的未成熟恒牙,其中由于大量冠状牙结构的丧失和改良的根尖成形术,将来可能需要一个桩/核进行适当的冠状面修复被使用了。改良根尖成形术后 10 例均未见临床症状/体征,2 年后复查显示根尖周病变愈合/愈合。8 例表现为根尖根管壁厚度增加,根尖长度增加,根尖闭合。根长的总体百分比变化为 7.52%,根尖 3分之1 处的根宽为 18.89%,在 24-72 个月的随访期,影像学根区为 15.04%。如果将来最终修复需要,这种改良的根尖成形术程序允许用桩/芯修复牙齿,并使牙根继续发育。

METHODS:BACKGROUND:The anterior oronasal fistulae neighboring the alveolar cleft could persist or reappear after the alveolar reconstruction with cancellous bone grafting. The persistent symptomatic anterior oronasal fistulae need to be repaired, but surgery remains a challenge in cleft care. Surprisingly, this issue has rarely been reported in the literature. The purpose of this long-term study was to report a single surgeon experience with a therapeutic protocol for persistent symptomatic anterior oronasal fistula repair. METHODS:This is a retrospective study of consecutive patients with Veau type III and IV clefts and persistent symptomatic anterior oronasal fistulae managed according to a therapeutic protocol from 1997 to 2018. Depending on fistula size, patients were treated with local flaps associated with an interpositional graft or two-stage tongue flaps (small/medium or large fistulae, respectively). The surgical outcomes were classified as "good" (complete fistula closure with no symptoms), "fair" (asymptomatic narrow fistula remained), or "poor" (failure with persistent symptoms). RESULTS:Forty-four patients with persistent symptomatic anterior oronasal fistulae were reconstructed with local flaps associated with interpositional fascia or dermal fat grafting (52.3%) or two-stage tongue flaps (47.7%). Most of patients (93.2%) presented "good" outcomes, ranging from 87% to 100% (local and tongue flaps, respectively). Three (6.8%) patients presented symptomatic residual fistula ("poor" outcomes). CONCLUSIONS:For the repair of persistent symptomatic anterior oronasal fistulae, this therapeutic protocol provided satisfactory outcome with low fistula recurrence rate.

METHODS:OBJECTIVE:Methadone is a vital treatment for women with opioid use disorder in pregnancy. Previous reports suggested an association between methadone exposure and Pierre Robin sequence (PRS), a rare craniofacial anomaly. We assessed the association between gestational methadone exposure and PRS. DESIGN/SETTING:This case-malformed control study used European Surveillance of Congenital Anomalies population-based registries in Ireland, the Netherlands, Italy, Switzerland, Croatia, Malta, Portugal, Germany, Wales, Norway and Spain, 1995-2011. PATIENTS:Cases included PRS based on International Classification of Disease (ICD), Ninth Edition-British Paediatric Association (BPA) code 75 603 or ICD, Tenth Edition-BPA code Q8708. Malformed controls were all non-PRS anomalies, excluding genetic conditions, among live births, fetal deaths from 20 weeks' gestation and terminations of pregnancy for fetal anomalies. An exploratory analysis assessed the association between methadone exposure and other congenital anomalies (CAs) excluding PRS. Methadone exposure was ascertained from medical records and maternal interview. RESULTS:Among 87 979 CA registrations, there were 127 methadone-exposed pregnancies and 336 PRS cases. There was an association between methadone exposure and PRS (OR adjusted for registry 12.3, 95% CI 5.7 to 26.8). In absolute terms, this association reflects a risk increase from approximately 1-12 cases per 10 000 births. A raised OR was found for cleft palate (adjusted OR 5.0, 95% CI 2.7 to 9.2). CONCLUSIONS:These findings suggest that gestational methadone exposure is associated with PRS. The association may be explained by unmeasured confounding factors. The small increased risk of PRS in itself does not alter the risk-benefit balance for gestational methadone use. The association with cleft palate, a more common CA, should be assessed with independent data.

METHODS::Orthopedic treatment to improve deficient maxillary growth of cleft lip and palate patients is an important part of treatment. The success of this treatment is strongly dependent on the time of initiation of therapy. There has been a large controversy in the available literature regarding the skeletal age of these patients. The aim of the present study was to compare the skeletal age of cleft lip and palate patients with normal individuals.37 unilateral and 14 bilateral cleft lip and palate patients and 47 healthy individuals participated in this cross-sectional study. The patients were classified into 8 to 10 and 11 to 14-year-old individuals. Cervical vertebral maturational stage of participants was evaluated in the lateral cephalometry. The skeletal age of cleft lip and palate patients was compared with normal controls. Chi-square was used for statistical analysis. There was not a significant difference in the skeletal developmental stage of unilateral and bilateral cleft compared to their normal peers according to their age and sex. Also, significant difference in skeletal maturational stage of cleft lip and palate patients was not found between boys and girls (P = 0.8). Similarly, no significant difference was found in the skeletal age of the 3 studied groups without considering the age and sex of participants (P = 0.5). Regarding the similar skeletal maturational stage of cleft lip and palate patients with normal controls in our study, their maxillofacial orthopedic treatment can be initiated at similar time to normal peers.
