Hemisection is the sectioning of teeth with multiple roots, the removal of the damaged root and its associated crown piece, and the preservation of the healthy root (with crown). When periodontal, resorption, perforation, or caries damage is limited to one root and the other root is still largely healthy, this treatment option may be taken into account. The right case selection is the most important component in determining the long-term success in such cases. This case report details the hemisection of a mandibular molar with root caries, followed by appropriate restoration.

To evaluate and compare the microleakage In class II restorations using open-and closed-sandwich techniques with zirconomer as an intermediate material. Material and methodTwenty-six non-carious mandibular first molars were selected and randomly divided into two groups (groups 1 and 2 where n=13). A standardized Class II preparation was made with the cervical margin 1 mm below the cementum-enamel junction. Samples of group 1 were restored using the open-sandwich technique and samples of group 2 with the close-sandwich technique, and zirconomer was used as an intermediate restorative material. Following that, the restorations underwent 200 heat cycles with dwell times of 20 seconds at 5°C and 55°C. Dye penetration and scanning electron microscope (SEM) analysis using the replica approach were used to assess adaptation at the cervical margin. The data were statistically analyzed using the Paired T-test (p<0.05). ResultsLower dye penetration was seen in the open-sandwich technique compared to the closed-sandwich technique (p<0.001). ConclusionWhen comparing the open-sandwich technique with the closed one, it was observed that less microleakage was seen in the open-sandwich technique as it has better marginal adaptation and fewer voids.

Pandemic can be described as the widespread occurrence of disease, which is more than what is usually expected in a geographical area. Presently the whole world is in a critical state for COVID -19 pandemic. On 11th March 2020, World Health Organization took out the census of the total cases of COVID-19 and it as a pandemic. On 14th April 2020, there were in total 1,925,571 affected cases worldwide, with a death count of 119,718 and a total of 452,188 recovered cases with India having total of 10, 453 cases with a death toll of 358. People of all ages have shown susceptibility. Mode of transmission is via big droplets expelled out by symptomatic patients while they cough or sneeze. So far there is no particular drug or vaccine present in the market which is specific to the treatment of this infection. Thus, there is over-burdening of the health care systems in all places. This novel virus outbreak has challenged the infrastructure of economy, medicine and public health of almost all the countries. Also, future outbreaks of viruses and pathogens are probable. So, besides counteracting this outbreak, we must also put our efforts in planning out comprehensive strategies to avoid any potential outbreaks of origin.

Traumatic dental injuries often occur to the teeth and their supporting tissues and they are the main reasons for an emergency visit to a dental clinic. Horizontal root fractures usually are characterized by a fracture line that is perpendicular to the long axis of the root. Root fractures are diagnosed through clinical and radiographic examination. Treatment depends on the position of the fracture, the extent of root involvement, correct diagnosis, clinical management, and radiographic follow-up. This article presents endodontic management of horizontal root fracture using a fibre post. A 28-year-old male patient presented with a horizontal fracture of the maxillary left central incisor at the junction of the apical and middle third of the root. Root canal treatment followed by MTA apexification of the coronal fragment and fibre post gave satisfactory results.

The current study aims to evaluate and compare the efficacy of light-cured calcium hydroxide and a fourthgeneration calcium silicate cement (TheraCal LC®) as indirect pulp capping (IPC) materials in patients with deep carious lesions. Materials and methodsA total of 28 patients were randomly divided into two groups (n=14). Group A was managed by light-cured calcium hydroxide, while group B was treated with TheraCal LC (a fourth-generation calcium silicate cement). Clinical examination was conducted to check for postoperative pain, tenderness, and neural sensibility, and radiographical examination was conducted to check for periodontal ligament space widening, presence of calcific barrier, and periapical radiolucency at patient recall of 21 days, three months, and six months. Primary and secondary outcome variables were based on clinical and radiographical success rates noted at six months' follow-up. ResultsSuccess rate for light-cured calcium hydroxide group at follow-up came out to be 0% at 21 days, 85.71% at three months, and 92.85% at six months. The success rate for TheraCal LC group came out to be 0% at 21 days, 92.85% at three months, and 100% at six months. The overall success rate for IPC procedure was 89.28% at three months' follow-up and 96.42% at six months' follow-up for both groups. The difference was statistically non-significant at the end of three and six months' follow-up. ConclusionWithin the limitations of our study, it was concluded that TheraCal LC can be used alternatively with lightcured calcium hydroxide in IPC, with a predictability of similar success outcome in patients with deep carious lesions.
