Partial Retention

Nine client-owned dogs presented with periodontally and/or endodontically involved mandibular or maxillary carnassial teeth that were either individually affected or adjacent to a jaw fracture. A total of 10 teeth were hemisected (8 mandibular first molar teeth and 2 maxillary fourth premolar teeth), and one crown-root segment was extracted for each tooth. Gingival tissues were approximated and sutured over the extraction sites, and the retained tooth portions were treated by means of standard root canal therapy or vital pulp therapy followed by standard root canal therapy. Retained crown-root segments of 2 of the 10 hemisected teeth were extracted following short- and long-term postoperative examinations due to continued periodontal complications. It was concluded that resection of a portion of a tooth can be a useful treatment for periodontally and/or endodontically involved carnassial teeth that are affected individually or located adjacent to a jaw fracture in dogs.

Background & Objectives:The success of root canal therapy greatly depends upon the proper cleaning, shaping and three dimensional sealing. Besides these, the locations of all the canals, is mandatory to achieve the rationale of endodontic therapy. Hence, variation in root canal anatomy has clinical significance. The objective of this study was to assess the presence of four root canals in permanent mandibular first molars in patients attending Dhulikhel Hospital.Materials & Methods:The clinical and radiographic examination of one hundred and nine permanent mandibular first molars, undergoing root canal treatment was conducted. Mandibular first molar teeth of both male and female patients of all age groups were included.Results:Out of 109 samples (46.8% male and 53.2% female), three and four canals were found in 44.1% and 55.9% respectively in root treated permanent mandibular first molars.Conclusion:This study concluded that 55.9% of permanent mandibular first molars have four root canals, indicating higher incidence than that of three canals, in patients attending Dhulikhel hospital.

Irreversible Pulpitis

Background and Objectives: Symptomatic irreversible pulpitis in permanent mature teeth is a common indication for nonsurgical root canal treatment (NSRCT), but contemporary studies have reported on vital pulp therapy (VPT) applied in such teeth as a less invasive treatment. This systematic review assessed the outcomes of VPT, including partial and full pulpotomy performed with hydraulic calcium silicate cements (HCSCs) in permanent mature posterior teeth diagnosed with symptomatic irreversible pulpitis. Materials and Methods: The PRISMA guidelines were followed. The search strategy included PubMed®, EMBASE, Cochrane library and grey literature electronic databases. The quality assessment of the identified studies followed the Cochrane Collaboration Risk of Bias, ROBINS-I and Newcastle–Ottawa Scale tools. Results: The search of primary databases identified 142 articles, of which 9 randomized controlled trials and 3 prospective cohort studies were selected for review. The risk-of-bias was assessed as ‘high’ or ‘serious’, ‘fair’, and ‘low’ for three, seven and two articles, respectively. One to five years after VPT using HCSCs, the success rates mostly ranged from 78 to 90%. Based on two articles, the outcomes of the VPT and NSRCT were comparable at one and five years. Despite the necessity for the intra-operative pulp assessment in VPT procedures, the majority of the studies did not fully report on this step or on the time needed to achieve hemostasis. Small sample sizes, of under 23 teeth, were reported in three studies. Conclusions: The reviewed 12 articles reported favorable outcomes of the VPT performed with HCSCs in permanent mature posterior teeth with symptomatic irreversible pulpitis, with radiographic success in the range of 81 to 90%. Two articles suggested comparable outcomes of the VPT and root canal treatment. Universal case selection and outcome criteria needs to be established for VPT when considered as an alternative to NSRCT. This evidence supports the need for further research comparing longer-term outcomes of both of the treatment modalities.

Radicular cyst as the most common odontogenic cyst usually arises from residual epithelial cells stimulated by inflammatory factors initiating by pulpal necrosis of a non-vital tooth. Radicular cyst is commonly asymptomatic, slow grower, and rarely invade near bony structures. Many treatment approaches are presented for a radicular cyst like surgical endodontic treatment, tooth extraction, enucleation, and marsupialization. In this case treatment plan compromised with root canal therapy and surgical enucleation of cystic lesion. This case report presents a large radicular cyst in a vital maxillary first molar with only one necrotic root canal secondary to direct pulp capping with mineral trioxide aggregate with buccal and palatal cortical bone perforation.

Background. The oral health care of autistic children is elaborated; they often fail to define dental problems, and a family-centered approach can be useful to improve and intercept these disorders. Aim. To assess the oral status of autistic children, comparing it with no autistic patients. Materials and Methods. A retrospective study analyzed the oral health status of 70 children, 35 with autism and 35 without the disorder. Conditions assessed were dental trauma type, periodontal tissue injuries, soft tissue lip injuries, different treatments carried out, associated soft tissue findings and disorders, and the long-term management. All patients (≤15 years of age) were chosen consecutively. Results. Females (57%) suffered more traumatic injuries than males (43%) in the autistic group, whereas males affected by dental trauma (54%) are predominant in the control group. The enamel fracture was the main finding among the dental trauma types in both groups followed by enamel/dentin/pulp fracture (31%), root fracture (11%), and avulsions (3%) in the autistic group and by avulsions (20%), root fracture (11%), and enamel/dentin/pulp fracture (6%) in the control group. The comparison of all variables of the two groups showed a statistically significant difference ( P < 0.012 ). The lower lip was statistically more injured than the upper lip ( P < 0.005 ). Conclusions. The composite restorative technique was the most common approach carried out; the long-term evaluation, when possible, was predominantly managed through root canal therapy in the control group (81%), and root canal therapy (50%) and tooth extraction (50%) in the sample group.

Canal Morphology

ABSTRACT Aim C-shaped canal system is a seldom-found root canal anatomy which displays a challenge in all stages of endodontic treatment. According to the literature, this type of canal morphology is not a common finding in the mandibular first molar teeth. Background This case report presents endodontic management of a mandibular first molar with a C-shaped canal system. Case report Root canal system was cleaned and shaped by nickel-titanium (NiTi) rotary instruments combined with selfadjusting file (SAF). Obturation was performed using warm, vertical condensation combined with the injection of warm gutta-percha. Follow-up examination 12 months later showed that the tooth was asymptomatic. The radiological findings presented no signs of periapical pathology. Clinical significance The clinician must be aware of the occurence and complexity of C-shaped canals in mandibular first molar teeth to perform a successful root canal treatment. The supplementary use of SAF after application of rotary instruments in C-shaped root canals might be a promising approach in endodontic treatment of this type of canal morphology.

Abstract Background: Jaw cyst is the most common disease of the oral and maxillofacial region. In addition to the pathogenic tooth, the roots of some teeth are often located in the cavity of the cystic capsule. Whether these involved teeth require root canal therapy and apicoectomy is still inconclusive. In the present study, we aimed to preserve the pulp activity of involved teeth in jaw cyst by improved operation.Methods: In our improved surgical method, the root canal therapy was not performed on the involved teeth, and no apical excision was performed during the operation. 63 involved teeth in 20 cases of jaw cyst treated by our department were selected between September 2015 and October 2017. The involved teeth were diagnosed by X-ray, CBCT, and a pulp vitality test before surgery. We observed the pulps' activity in the involved teeth and the efficacy of surgery for 12-36 months.Results: Electrical activity test of 63 involved teeth pulp in 20 patients with jaw cyst was normal or insensitively before operation. The involved teeth were preserved by improved surgical method. After 12-36 months’ follow-up, the pulp activity of 53 involved teeth (84.1%) were preserved, whereas 10 teeth (15.9%) showed adverse symptoms such as redness and swelling in the apical area, fistula, and pain. These symptoms resolved after postoperative root canal therapy. Chewing function was restored well. There was no recurrence and the bone cavity gradually reduced and finally disappeared, and bone density returned to normal after long term follow-up.Conclusion: Our results showed that to preserve the activity of the involved teeth for the treatment of jaw cyst by performing an improved operation method was effective.
