As the number of aged people in the world is growing, the need to provide patients with tooth alternate through removable partial dentures is equally growing. There are adversarial effects that should be kept in mind which might disturb the remaining teeth; specially, the abutments and the supporting tissues. These effects might spread to the muscles of mastication and also to the supporting periodontal tissues. Thus, we should plan removable partial dentures (RPDs) without mutilation to the adjacent teeth or the underlying tissues.

Dentists encounter a wide range of hard-tissue injuries in practice. Dental extractions are one of the most common procedures in dentistry and may lead to several complications, including oral sinus complications, osteitis, infection, dysesthesia, pain, and bleeding.

The aim of the study was to determine and compare the shear bond strength of brackets bonded with Adper Promt self-etching adhesive (3M ESPE), Xeno III self-etching adhesive (DENSPLY), Transbond plus self-etching adhesive (3M) with that of conversional bonding procedure, and to calculate the adhesive remnant index (ARI).Totally, 60 maxillary premolar teeth were collected, and divided into Group I (Blue): Transbond XT primer, Group II (Purple): Adper Prompt self-etching adhesive, Group III (Orange): Xeno III self-etching adhesive, Group IV (Pink): Tranbond Plus self-etching adhesive.The results of the study showed there was no statistical significance in the shear bond strength according to an analysis of variance (P = 0.207) of the four groups. The mean shear bond strength of Groups I, II, III, IV were 14.56 2.97 Megapascals (MPa), 12.62 2.48 MPa, 13.27 3.16, and 12.64 2.56, respectively. Chi-square comparison for the ARI indicated that there was a significant difference (P = 0.003) between the groups.All the four self-etching adhesives showed clinically acceptable mean shear bond strength. The ARI score showed a self-etching adhesive the debonding occurred more within the adhesive interface leaving less composite adhesive on the tooth surface making it easy to clean up.

For proper intercuspation, the teeth must be proportional in size. If teeth are mismatched, with unusually large teeth in one arch compared to the other, then an ideal occlusion cannot be attained. This study has been done to determine the prevalence of tooth size discrepancies among orthodontic patients in general and also between different malocclusion groups, sex, and to analyze the change in the degree of severity in Bolton discrepancy before and after the hypothetical premolar extraction.The study was carried out on randomly collected 100 pre-treatment dental casts. Tooth size analyses were performed on these pre-treatment models and Mesio distal tooth size ratios were measured as described by Bolton before and after various patterns of hypothetical extraction.The results were statistically evaluated using ANOVA and paired samples t-test. 5 out of 100 patients are seen with severe Bolton discrepancy with Bolton values (BV) ranging above and below 2 standard deviation. Statistically insignificant difference is seen between males and females and also between various groups of malocclusion. The difference between the pre-treatment and post extraction BV was found statistically significant for the first premolar extraction and insignificant for others.The results of this study indicate a new point of view to the question of which teeth to extract when evaluated for tooth size aspect only.

The radio-sensitivity of a tissue or organ is measured by its response to irradiation. Loss of moderate numbers of cells does not affect the function of most organs. However, with loss of large numbers of cells, all affected organisms display a clinical result. The severity of this change depends on the dosage and thus the extent of cell loss. Moderate doses to a localized area may lead to repairable damage. Comparable doses to a whole organism may result in death from damage to the most sensitive systems in the body.

Periodontitis is an inflammatory disease affecting the periodontium i.e. the tissues that surround and support the teeth. Periodontitis manifests as progressive loss of the alveolar bone around the teeth, and if left untreated, can cause loosening and subsequent loss of teeth. Periodontitis is initiated by microorganisms that adhere to and grow on the tooths surfaces, besides an over -aggressive immune response against these microorganisms. The primary goal of periodontal therapy is to preserve the natural dentition by accomplishing and preserving a healthy functional periodontium. Many treatment modalities have been introduced to improve the therapeutic result of periodontal treatment which may also damage the periodontiumiatrogenically.

The principal reason of gingival inflammation is bacterial plaque, along with other predisposing factors. These predisposing factors are calculus, malocclusion, faulty restorations, complications associated with orthodontic therapy, self- inflicted injuries, use of tobacco & radiation therapy. The contributing factors to gingival inflammation & periodontal destruction are deficient dental restorations and prosthesis. Inadequate dental procedures that add to the weakening of the periodontal tissues are referred to as iatrogenic factors.

A dental implant (also known as an endosseous implant or fixture) is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor.Well planned, comprehensive treatment plans lead to successful implant treatment and patient satisfaction, which are the eventual long-term objectives. Probability of implant success can be put at jeopardy by absolute and relative risk factors.

Lasers have been used in dentistry since 1994 to treat a number of dental problems. A variety of lasers are now available for use in dentistry. Once stated as an intricate technology with restricted usage in clinical dentistry, there is a growing awareness of the usefulness of lasers in the armamentarium of the modern dental practice, where they can be used as an adjunct or alternative to various long-standing approaches.

In the present case of a 35-year old patient, platelet-rich fibrin, which is an autologous platelet concentrate, was used to fill the osseous defect following surgery. The case was assessed both clinically and radiographically for a period of 9 months.
