Management of wide open apices in non-vital permanent teeth with Ca(OH)2 paste

A retrospective study on 15 non-vital immature incisor teeth was done using Ca(OH)2 Pulpdent® paste. A success rate of 100 percent was achieved within one year. The variables influencing the time taken for apexification were also evaluated. The teeth were followed up to a period of 24 months. It was found that older children having narrow open apex had a shorter treatment time than the younger children (NS); teeth without periapical infection showed some amount of root growth and closing of apex that was faster than those with periapical infection (p<0.001). The calcified bridge formed following apexification is a porous structure. This investigation provides information about the time taken and procedure required to achieve apical barrier formation in non-vital immature incisors.

BackgroundRectal biopsy for the diagnosis for Hirschsprung's disease (HD) can be performed in several ways. Suction rectal biopsy (SRB) is the most widely used method for neonates and younger infants while open strip biopsy (OSB) is reserved for older children. Current notions suggest that SRB should not be used in older infants due to perceived thicker fibrous tissue in their rectal walls leading to higher rates of inconclusive results. This study aims to compare the inconclusive rates of both methods in children of different age groups.MethodsA retrospective study were carried out with patients aged 13 years who underwent SRB or OSB during a 4-year period in a single center. Rectal biopsies were performed on patients with HD with previous endorectal pull-through surgeries excluded. Primary outcomes were rates of inconclusive results for SRB and OSB overall and when divided into different age groups.Results79 biopsies (57 SRB and 22 OSB) were included in the study. 12 biopsies (9 SRB and 3 OSB) were deemed inconclusive. There was no significant difference in the rate of inconclusive results between patients underwent SRB and OSB overall (15.8% vs 13.6%, p=1.000). The same results were obtained when patients were divided into under one year and over one year groups or other different age groups (30.0% vs 33.3%, p=1.000).ConclusionsDespite low biopsy numbers, our study suggests that SRB provides comparable rates of inconclusive results with OSB in children of all age groups.

Objective: To evaluate the clinical and radiological outcome of MTA in nonvital teeth with open apices. Methods: Twenty-five non-vital teeth with open apices were treated with MTA apexification procedure. Standard endodontic procedures were followed and an apical plug of at least 5 mm was created by using MTA after a calcium hydroxide intra-canal dressing for at least 1 week. Final obturation was done after 24 hours by vertical compaction technique using gutta percha. Patients were recalled at 3, 6, 9 and 12 months interval. Clinical outcome was evaluated by assessing pain, tenderness, mobility and sinus tract. Blind to the treatment record, two examiners assessed the pre-treatment and post-treatment radiographs. Each radiograph was scored with the Periapical Index (PAI) and the size of the apical lesion was measured. The presence of an apical bridge over MTA was also noted. Results: Clinically 92% success rate was found whereas radiologically absolute success rate was 84%. Before treatment the mean PAI was 3.6 and mean size of the lesion was 3.24 mm. But, after 12 months follow up, the mean PAI was 1.36 and the mean lesion size was 0.68 mm. An apical barrier over MTA was distinguishable in 5 cases. Conclusion: Apexification using MTA can be considered as a predictable treatment option than calcium hydroxide apexification. DOI: http://dx.doi.org/10.3329/updcj.v3i2.17994 Update Dent.

ABSTRACT Objective: To consider the effectiveness of early treatment using one mixed-dentition approach to the correction of moderate and severe Class II malocclusions. Materials and Methods: Three groups of Class II subjects were included in this retrospective study: an early treatment (EarlyTx) group that first presented at age 7 to 9.5 years (n = 54), a late treatment (LateTx) group whose first orthodontic visit occurred between ages 12 and 15 (n = 58), and an untreated Class II (UnTx) group to assess the pretreatment comparability of the two treated groups (n = 51). Thirteen conventional cephalometric measurements were reported for each group and Class II molar severity was measured on the study casts of the EarlyTx and LateTx groups. Results: Successful Class II correction was observed in approximately three quarters of both the EarlyTx group and the LateTx group at the end of treatment. EarlyTx patients had fewer permanent teeth extracted than did the LateTx patients (5.6% vs 37.9%, P < .001) and spent less time in full-bonded appliance therapy in the permanent dentition than did LateTx patients (1.7 ± 0.8 vs 2.6 ± 0.7years, P < .001). When supervision time is included, the EarlyTx group had longer total treatment time and averaged more visits than did the LateTx group (53.1 ± 18. 8 vs 33.7 ± 8.3, P < .0001). Fifty-five percent of the LateTx extraction cases involved removal of the maxillary first premolars only and were finished in a Class II molar relationship. Conclusion: EarlyTx comprehensive mixed-dentition treatment was an effective modality for early correction of Class II malocclusions.

Autologous Platelet

The use of autologous platelet concentrates (APCs) in regenerative endodontic procedures is inconsistent and unclear. The aim of this meta-analysis was to evaluate the effectiveness of autologous platelet concentrates compared to traditional blood-clot regeneration for the management of young, immature, necrotic, permanent teeth. The digital databases MEDLINE, SCOPUS, CENTRAL, Web of Science, and EMBASE were searched to identify ten randomized clinical trials. The outcomes at postoperative follow-up, such as dentinal wall thickness (DWT), increase in root length (RL), calcific barrier formation (CB), apical closure (AC), vitality response (VR), and success rate (SR), were subjected to both qualitative synthesis and quantitative meta-analysis. The meta-analysis showed that APCs significantly improved apical closure (risk ratio (RR) = 1.17; 95% CI: 1.01, 1.37; p = 0.04) and response to vitality pulp tests (RR = 1.61; 95% CI: 1.03, 2.52; p = 0.04), whereas no significant effect was observed on root lengthening, dentin wall thickness, or success rate of immature, necrotic teeth treated with regenerative endodontics. APCs could be beneficial when treating young, immature, necrotic, permanent teeth regarding better apical closure and improved response to vitality tests.

Favorable Conditions

The treatment of immature necrotic permanent teeth with wide open apices often poses a significant challenge for the clinician. The lack of an apical stop complicates the obturation and achievement of good apical seal in such teeth. The treatment of choice for necrotic teeth with immature root is apexification, which is induction of apical closure to produce more favorable conditions for conventional root canal filling. The most commonly advocated medicament is calcium hydroxide. But the disadvantages of long treatment time, tooth fracture risk and incomplete calcification of apical bridge have led to the development of newer biocompatible materials which can complete apexification in a single visit. Although different materials are available, Mineral Trioxide Aggregate (MTA) remains the material of choice for forming an immediate apical barrier because of its superior clinical properties and high success rate. This case series highlights the use of MTA for formation of hard tissue barrier in nonvital permanent teeth with open apices with demonstrated clinical and radiographic success.

Present Case Study

Trauma pada gigi permanen imatur non vital dengan apikal terbuka sering terjadi dan melibatkan kurang lebih 30% populasi anak. Mineral trioxide aggregate (MTA) adalah bahan pilihan terbaik yang dipakai sebagai bahan apeksifikasi untuk pembentukan apikal barrier dan penyembuhan pada gigi imatur. Tujuan laporan kasus adalah untuk melaporkan keberhasilan penutupan apikal dengan menggunakan MTA pada gigi permanen insisivus non vital dengan apikal terbuka yang diakibatkan trauma. Pasien perempuan 18 tahun dengan keluhan gigi depan atas kanan patah dan berubah warna. Kejadian trauma sejak 6 tahun yang lalu karena jatuh dari sepeda. Pemeriksaan klinis, gigi non vital dengan fraktur Ellis klas IV disertai apikal terbuka dan diskolorasi oleh karena trauma. Periapikal radiografis menunjukkan apikal masih terbuka dengan saluran akar yang besar serta terdapat radiolusensi periapikal. Apeksifikasi dilakukan dengan MTA dilanjutkandengan pemasangan pasak pita fiber, pembuatan inti dan restorasi mahkota jaket porselin fusi metal. Simpulan hasil perawatan menunjukkan bahwa apeksifikasi dengan MTA dapat mempersingkat waktu kunjungan dengan pembentukan barier apikal yang merangsang penyembuhan dan dapat langsung dilanjutkan dengan restorasi akhir.Apexification With Mineral Trioxide Aggregate In Right Maxillary Incisor. Traumatic injury in non-vital immature permanent teeth with open apex is common, and it comprises approximately 30% of the pediatric population. Mineral trioxide aggregate (MTA) is the best material to be used as an ingredient for apexification procedure for apical calcific barrier formation and healing. The aim of the present case study is to overview the successful closure of root apex in pulpless permanent incisors with wide open apices as a consequence of trauma using MTA. The examination was conducted to an 18 year-old female patient who complained about her broken and discolored right upper front teeth. The traumatic injury of her teeth had happened since 6 years ago after she fell from bike. On clinical examination, she suffered from non-vital teeth with fracture Ellis class IV, apex open and discoloration accompanied by trauma. Periapical radiographic evaluation showed that root formation with wide open apices with root canal was large and indicated a periapical radiolucency. Therefore, apexification with MTA was performed followed by ribbon fiber-reinforced, core making and restoration of full crown porcelain fusion metal. From the treatment, it can be concluded that the time visit for apexification treatment using MTA is shortened, and MTA can heal and stimulate apical barrier formation immediately after final restoration.
