Teeth Extraction

Purpose: The aim of this work was to analyse all the applied movements when extracting healthy upper and lower jaw premolars for orthodontic purposes. The authors wanted to demonstrate that the different bone densities of the mandible and maxilla are not a significant parameter when related to the extraction force applied. The buccal and palatal rocking movements, plus the twisting movements were also measured in this in-vivo study during premolar extraction for orthodontic purposes. Methods: The physical strains or forces transferred onto the teeth during extraction are the following three movements: gripping, twisting, and traction. A strain measurement gauge was attached onto an ordinary dentistry plier. The strain measurement gauge was constituted with an extensimetric washer with three 45º grids. The system operation was correlated to the variation of electrical resistance. Results: The variations of resistance (∆R) and all the different forces applied to the teeth (∆V) were recorded by a computerized system. Data results were processed through Microsoft Excel. The results underlined the stress distribution on the extracted teeth during gripping, twisting and flexion. Conclusions: The obtained data showed that the strength required to effect teeth extraction is not influenced by the quality of the bone but is instead influenced by the shape of the tooth’s root.

Objectives: The aim of this study was to evaluate the clinical performance of a nano filled flowable and nano hybrid bulk fill resin composite in class I restorations. Methods and Materials: Twenty patients were selected for this in vivo study. Each patient received at least one pair of restorations, restored with nano hybrid bulk fill resin composite (IPS Empress direct [IED]) and nano hybrid Tetric N Ceram flowable composite [TNC]. Each restorative resin system was used with its respective adhesive system according to manufacturers’ instructions. A total of 40 class I restorations were placed by one operator.  Restorations were blindly evaluated by two examiners at baseline and 3, 6, and 12 months respectively using modified US Public Health Service Ryge criteria. The data obtained was statistically analyzed using Chi square test to compare the two restorative materials for each category. Results: At 3, 6 and 12, months, recall rate was 100%, 95% and 85%, respectively, with a retention rate of 100%. There were statistically significant differences between the two restorative resins in terms of marginal adaptation and marginal discoloration (p<0.05). No differences were observed between the restorative resins in terms of retention (p<0.05). None of the restorations showed postoperative sensitivity, or loss of anatomic form. Conclusion: Within the limitations of this study, nano hybrid bulk fill composite resin viz. IPS EMPRESS DIRECT showed better clinical performance than nano filled flowable composite in terms of marginal discoloration and marginal adaptation.

Isolation Methods

Context: A proper isolation technique plays a key role in the success of restoration of carious tooth. Aim Of The Study: The aim of this in-vivo study was to evaluate efficacy of addition silicone dam coverage technique with conventional isolation methods in restorative procedures and endodontic treatment. Settings And Design: Forty-Five patients who fulfill the inclusion criteria were selected for the study. Materials And Methods: All the participants underwent clinical procedures using 3 different isolation techniques. Group-1: Clinical procedures were carried out using traditional cotton roll isolation. Group-2: Clinical procedures were carried out using conventional rubber dam isolation procedure. Group-3: Clinical procedures were carried out using addition silicone dam coverage technique. The efficacy of isolation in terms of clinician usage and patient comfort is evaluated by a single evaluator. The results were tabulated and statistically analyzed. Statistical Analysis: IBM SPSS (version 21.0) software was used. Chi-square test was performed, considering P < 0.05 for statistical significance. Results: All the groups demonstrated satisfactory clinical performance. Upon inter and intra-group comparison of the isolation methods, there was statistically significant difference (P > 0.05). Conclusion: It is important to achieve an aseptic environment in clinical restorative and endodontic procedures. Addition silicone dam coverage technique is a chair side modified design which is user friendly with improved treatment efficacy. However, long-term clinical studies must be needed for further evaluation.

Bulk Insertion

This in vivo study evaluated the clinical performance of class II restorations, in primary molars after 12 months. Three restorative techniques were used: filling the cavities in bulk; filling with three horizontal increments and placement in three horizontal increments using pre-polymerized composite inserts. The composite resin used was Prisma TP.H (Caulk-Dentsply) with the adhesive system ScotchbondMultipurpose (3M). Initially 90 class II restorations were placed in 27 patients from 8 to 10 years of age and followed-up for 12 months. After this period 55 restorations were evaluated for anatomic form, color alterations at the margins, presence of decay and marginal adaptation. The results showed that all groups presented similar rates of wear, the bulk insertion technique showed better results for marginal adaptation, color alterations of the margins and less presence of caries at occlusal margins, and that composite resin TP.H could be used in class II restorations in primary molars.
