The use of plasma-rich growth factors (PRGF) in oral surgery.

The therapeutic objective of utilizing growth factors in oral surgery is to improve upon the body's regenerative capacity. In many situations, the unaided regeneration process is insufficient to allow complete repair of both bone and soft tissues. This article presents two clinical cases that describe different applications of growth-factor preparation applied at the surgical site in order to stimulate regeneration of osseous and epithelial tissues. Both clinical cases demonstrate the therapeutic effectiveness of utilizing the described technique for the incorporation of plasma-rich growth factors as an adjuvant in regenerative procedure.

Retrospective survey of dental anomalies and pathology detected on maxillary occlusal radiographs in children between 3 and 5 years of age.

PURPOSE: Radiographs play an important role in the diagnosis of anomalies and pathology of the oral structures of young children as well as in the interception and management of developmental problems in the dentition. The occlusal film, commonly indicated in the young child, is a helpful tool in establishing a baseline and in revealing certain region-specific dental concerns in a timely fashion. The purpose of this retrospective study was to perform a comprehensive examination of maxillary occlusal radiographs in a clinical pediatric population and to determine the prevalence of dental anomalies and pathology in the premaxilla in children between 3 and 5 years of age. METHODS: Radiographs of healthy preschool children (236 males and 264 females), who received their initial examination at the University of Texas-Houston Pediatric Dentistry Graduate Clinic during 1997 and 1998, were reviewed independently by two pediatric dentists, using a 2X magnifying lens and a standard dental light box. Interexaminer discrepancies were resolved by consultation and mutual agreement. RESULTS: Ninety-two (18%) showed no evidence of dental caries, restorations, current pathological conditions, or other anomalies. Frequencies of anomalies such as congenitally missing and supernumerary teeth were consistent with other reports. CONCLUSIONS: These observations emphasize the importance of obtaining intraoral radiographs on preschool children who are in apparent good dental health.

Preformed posterior stainless steel crowns: an update.

For almost 50 years, dentists have used stainless steel crowns for primary and permanent posterior teeth. No other type of restoration offers the convenience, low cost, durability, and reliability of such crowns when interim full-coronal coverage is required. Preformed stainless steel crowns have improved over the years. Better luting cements have been developed and different methods of crown manipulation have evolved. This article reviews stainless steel crown procedures for primary and permanent posterior teeth. Step-by-step placement of a primary molar stainless steel crown is documented and permanent molar stainless steel crown restoration is described. A method for repairing a worn-through crown also is reviewed.

[Occlusal contact force and stress analysis of molars with vertical root split].

OBJECTIVE: To study the induction of vertical root split by occlusal force. METHODS: 1. The occlusal contact force was studied in 34 cases (39 teeth) by photocclusion. 2. The stress analysis for the first mandicular molar was studied by three-dimensional definite element. RESULTS: 1. The occlusal contact force didn't distribute balancedly in 26 cases (31 teeth) and the suffering teeth bore greater force. 2. The bucco-lingual central line of the mesial root canal wall underwent greater tensile stress when tooth bore load with 30 degrees angle to axis, or buccal-lingual lateral load or logitudinal occlusive load on the masial or distal cusp. CONCLUSION: The vertical root split of molar is associated with greater occlusal force and the stress that concentrated on the buccolingual central line of the mesial root wall for a long time.

Pulp-dentin biology in restorative dentistry. Part 7: The exposed pulp.

Exposure of the dental pulp, through a caries lesion, accidentally during routine cavity preparation, or as a result of tooth fracture, is a clinical reality that requires optimal treatment. The potential for healing by formation of a dentinal bridge is good, provided that the pulp is not inflamed. Calcium hydroxide has a long history of inducing dentinal bridge formation to promote successful healing. Resin composites are emerging as alternative materials for pulp capping, but healing is slower, and relatively little clinical experience is available for analysis. The prognosis for healing is poor after exposure of an inflamed pulp. Pulpotomy should be considered to create a wound in an uninflamed location. If an exposure is expected through a caries lesion, stepwise excavation of the carious dentin should be considered to allow healing of the dentin and pulp prior to the final excavation of the carious dentin.

Achieving ultimate anterior esthetics with a new microhybrid composite.

Direct bonding is one of the most commonly used forms of restoration for the conservative esthetic improvement of anterior teeth. The major challenges involve selecting composites that have adequate strength as well as provide lifelike optical properties that render the restoration functionally sound and esthetically pleasing. Properties such as high sculptability, wide shade range, varying opacities and translucency, as well as high polishability are essential for gaining absolute control over the restorative process and the attainment of natural-looking results. This article discusses a new composite restorative system and its application in the direct esthetic and functional rehabilitation of the anterior dentition.

Restoration and reinforcement of endodontically treated teeth with a polyethylene ribbon and prefabricated fiberglass post.

In the past it was considered appropriate to place a cast post and core in every pulpless tooth without regard to the remaining supportive tooth structure present. Recent research and the advent of adhesive bonding techniques have caused clinicians to reevaluate their restorative protocol. This article reviews the current literature with regard to restoration of the endodontically treated tooth and presents a method for restoration and reinforcement utilizing a combination of polyethylene ribbon and a prefabricated fiberglass post.

Changes in prevalence and treatment need for traumatic dental injuries among 14-year-old children in Newham, London: a deprived area.

OBJECTIVE: The study was carried out to assess the prevalence of traumatic injuries to the permanent incisors of 14-year-old schoolchildren in Newham in 1998-99, the treatment needed and to compare the results with data from 1995-96. Also, to test whether different levels of deprivation within an area would increase the risk of dental injury. BASIC RESEARCH DESIGN: A cross-sectional study was carried out. One dentist (SM) carried out all dental examinations. Upper and lower permanent incisors were examined for dental injuries. The examiner recorded the type of damage sustained, any treatment carried out and the treatment need. PARTICIPANTS: 411 14-year-old schoolchildren in Newham in 1998-99. Results The prevalence of traumatic injuries was 43.8% (95% CI 39.0, 48.7) in 1998-99, compared to 23.7% (95% CI 22.0, 25.5) in 1995-96. Boys sustained statistically significantly more dental injuries than girls, 50.2% and 37.1% respectively (P<0.01). In 1998-99 92.7 per thousand incisors were damaged, 6.7 per thousand incisors were treated and 28.9 per thousand incisors needed treatment. Two components of the Jarman Index were associated with dental injuries. Overcrowded household was statistically significantly related to dental injuries in both studies. Ethnicity was associated with dental injury in 1998-99, but not tested in 1995-96. CONCLUSIONS The prevalence of traumatic dental injury in Newham increased from 23.7% to 43.8% between 1995-96 and 1998-99, it was higher than the overall prevalence in the United Kingdom (17%) and its treatment had been neglected. Area-based measures of deprivation such as an overcrowded household and ethnicity were predictors of traumatic dental injuries.
