Influence of Lateral Pressure on Sectional Matrix
Condition: Class II Dental Caries
MeSH terms: Dental Caries
Study type: Interventional

Summary: 
      The aim of this study was evaluating the clinical effectiveness of the hand instrument in
      conjunction with sectional matrix when applying lateral forces at the contact area during
      curing to achieve large and tight proximal contacts in posterior teeth.
    

Detailed description: 
      Dental caries is considered as one of the most prevalent oral infections. Initiation of
      dental caries is a mufti-factorial process, its risk factors includes high loads of
      cariogenic bacteria, increased frequency of sugar intake, insufficient exposure to fluoride
      and reduced salivary flow. Other factors that may influence the occurrence of caries include
      poor oral hygiene and socio-economic status.

      Inter-proximal caries lesions develop between the contacting proximal surfaces of two
      adjacent teeth. Massive evolution took place in restorative techniques, composite resin
      materials, cavity designs and armamentarium in the past few decades. As well as drastic
      solutions for earlier problems of composite resins such as bonding to dentin, wear
      resistance, postoperative sensitivity and polymerization shrinkage. Despite all the progress
      noted in that area, still achieving proximal contact tightness in Class II resin composite
      restorations is considered one of the biggest challenges facing clinicians Proximal contact
      tightness is a physiological dynamic entity of multifactorial origin that is largely affected
      by tooth type, location, time of day, patient position, mastication and restorative
      procedures Failure to obtain proper proximal contact area will influence stability of dental
      arch and transmission of forces along long axis of teeth during mastication. Traumatic
      masticatory forces can lead to various problems like; rotation and displacement of the teeth,
      lifting forces on the teeth, deflective occlusal contacts and food impactions that would
      result in trauma, pain, inflammation and bleeding of the periodontium. The contact must be
      neither open nor too tight.

      Aim of this study was evaluating the clinical effectiveness of the Optra Contact in
      conjunction with sectional matrix when applying lateral forces at the contact area during
      curing to achieve large and tight proximal contacts in posterior teeth.
