Introduction: Non carious cervical lesion, (NCCL) is the loss of tooth structure at the cemento enamel junction, or CEJ level that is unrelated to dental caries. These lesions can affect plaque retention, tooth sensitivity, structural integrity, caries incidence, and pulpal vitality. Objectives: To compare clinical effectiveness of Cention–N and Nanohybrid composite resin as a restoration of non-carious cervical lesion for gross fracture, marginal integrity & surface texture. Materials and Methods: Total 24 patients having two class V non-carious cervical lesion in the same arch, approximately of same size and shape were selected. Entire study was carried out by two operators. Both teeth were restored, finished and polished by one operator with Cention–N and Tetric N Ceram (Ivoclar – Vivadent) respectively. Evaluation for marginal integrity & surface texture was done by second operator on the same day of restoration. (USPHS, Ryge criteria for direct clinical evaluation). Follow up was done for gross fracture, marginal integrity & surface texture after 1 week, 1 month, 3 month & 6 month. All the data were collected according to USPHS, Ryge Criteria. Statistical analysis was done by chi square test. Results: Cention–N is as effective as Tetric-N-Ceram for gross fracture and marginal integrity till 6 months. But Cention–N showed inferior surface characteristics than Tetric-N-Ceram after 1 week. Conclusion: Cention – N is as effective as Tetric N Ceram for gross fracture and marginal integrity but Cention – N has an inferior surface characteristics than Tetric N Ceram.

Aim: The present in-vitro study evaluated the influence of different organic and inorganic root canal irrigants used during chemomechanical preparation on the push-out bond strength of an Epoxy-resin based AH Plus sealer and a Bioceramic Endosequence BC sealer. Materials and Methods: Eighty extracted permanent human mandibular single rooted premolar teeth were used and randomly assigned to four major groups [according to irrigation protocol using sodium hypochlorite (NaOCl) with MTAD (mixture of tetracycline, acid and detergent) or ethylenediaminetetraacetic acid (EDTA) or phosphoric acid or normal saline (NS) as control group]. The root canals were instrumented using rotary nickel-titanium Hyflex® CM file system to size 30/0.06 taper, at the working length, as final shaping and finishing file, following different irrigation protocols, as per group allocation. The samples were further subdivided into two groups, with ten samples each (n=10), based on endodontic sealer; roots were obturated with gutta-percha and test sealers (AH-Plus or Endosequence Bioceramic sealer). The teeth were decoronated and obtained samples of eighty obturated roots of eight groups were cut to obtain 2mm thick coronal root slices (10 root section in each group), using hard tissue microtome. Bond strength of sealers was then measured by subjecting each root section to a compressive load via Instron Universal testing machine. The data were tabulated and statistically analyzed using analysis of variance (ANOVA) and Tukey’s HSD along with Bonferroni’s post-hoc test and level of significance set at a p value<0> Results: The highest mean push-out bond strength of 5.38 MPa for AH Plus sealer was obtained in Group 2A followed by 3.94 MPa for Endosequence BC sealer (Group 2B), when phosphoric acid was used as chelating agent. However, mean bond strength of AH Plus sealer was significantly decreased (p<0> Conclusion: The Bioceramic based Endosequence BC sealer and gutta-percha core combination was not superior in push-out bond strength to AH Plus and gutta-percha core combination. Moreover, use of different organic and inorganic endodontic irrigants influenced the push-out bond strength of both the sealers. Clinical Significance: In dynamic clinical situation, for longer functional viability of an endodontically treated tooth, adhesion of a sealer to root dentin is necessary to avoid its dislocation during tooth flexure and also even during operative procedures like post space preparation. Adequate measures should be undertaken while using different irrigation protocols bearing in mind that the canal irrigants used during chemomechanical preparation can affect root dentin surface, thereby influencing sealer adhesion.

Background: To study the prevalence of oral mucosal lesions/conditions in the 35-44 age group of adults of Patnacity, Bihar, India. Aims and Objectives: This study aims to assess the prevalence and describe the epidemiology. Materials and Methods: A Hospital based survey was carried out among patients attending the outpatient Department of Oral Medicine & Radiology in Buddha Institute of Dental Sciences & Hospital, patients aged 35-44 year age group as per the index age group as per the World Health Organization’s Basic Oral Health Survey’s Criteria. Result: The present study was designed on 1200 subjects to assess the prevalence of oral mucosal lesion who visited our department seeking dental treatment. The result showed that leukoplakia was the most prevalent in our population. More subjects with leukoplakia of 40-44 years in our population were males. Lesion was more prevalent in buccal mucosa and lichen planus had female predeliction in the age group of 35-40 years of age. The lesion was more prevalent in buccal mucosa.

Mandibular molars are the first teeth to erupt in the oral cavity having high caries susceptibility index, which actually necessitates cautious oral hygiene measures. Any deprivation in the upkeep may prompt significant issue like furcation involvement.Advances in dentistry, and the expanded wants of patients to keep up their dentition, have led to treatment of teeth that once would have been removed. Bicuspidization is a surgical procedure performed on the mandibular molars for the partition of the mesial and distal roots with their individual crown divides; this detachment takes out the existence of a furcation and encourages viable oral hygiene practice. A 30-year-old female patient reported with the chief complaint of pain and food lodgement in right mandibular first molar. On examination, the tooth was sensitive to percussion and revealed Grade I mobility. On radiographic examination, bone loss was evident in the intra- radicular area. Root canal treatment was done followed by bicuspidization of tooth.

The progressing inflammatory periodontal disease, if left untreated, results in attachment loss. This can also affect the bifurcation or trifurcation of a multirooted teeth. Thus, the treatment and long-term retention of mandibular molar teeth exhibiting furcation involvement has always been a key challenge, especially when there is furcation involvement progressed to a class II furcation. Hemisection denotes the removal of compromised root and its associated crown portion with the loss of periodontal attachment and to maintain the original tooth structure to attain the fixed prosthesis. This case report demonstrates the successful management of hemisection of 36 with occlusal rehabilitation and it was aimed to follow a conservative treatment approach to retain as much as original tooth structure possible against the conventional option of extracting the natural tooth.

Over denture is a one of the recommended treatment modality for aged patients with few remaining teeth with severely resorbed ridges. Root stumps under the denture base preserve further resorption of alveolar ridge which provides sensory feedback and improves the stability of the dentures. Moreover, the use of copings (short/long) and attachments on the remaining teeth after enododontic therapy enhances the retention of the denture. Success for the treatment depends on strategic selection of teeth. The present case report demonstrates the successful preservation of few remaining teeth to support tooth-retained overdenture. This treatment modality was selected considering the favorable inter ridge distance and economical status of the patient rather than complete extractions followed by complete denture or implant supported overdenture.

Intrusive luxation of permanent mature teeth is one of the most serious injuries to the periodontal ligament in dental traumatology. Intrusive luxation of permanent mature teeth is one of the most serious injuries to the periodontal ligament in dental traumatology. Intrusive luxation of mature permanent teeth is one of the most serious injuries as it involves soft tissue as well as periodontium. Various treatment modalities are practiced depending on amount of intrusion and tooth response to treatment. The damage caused by trauma to the surrounding soft and hard tissue results in a multitude of complications during the treatment planning. This case report presents careful repositioning of the intruded tooth by removable orthodontic means, periodontal treatment including crown lengthening and prosthodontic rehabilitation including fixed prosthesis to provide the most acceptable aesthetic outcome. The present report emphasizes the importance of a multidisciplinary approach to provide complete rehabilitation of a traumatically intruded permanent tooth.
