The most prevalent tooth form in both men and women was ovoid, and the least prevalent was square. The association between face shape and tooth form was not significant and did not abide by William's "Law of Harmony." However, there was an association between face shape and gender.

Background:Latex protective barriers such as gloves and rubber dam material have been used widely in restorative procedures for crown and bridge. However, the chemical used during latex glove fabrication is thought to inhibit the polymerization of elastomeric impression materials used for impression making which has a detrimental effect on the dimensional accuracy and surface definition of resultant casts used for restorative procedures. The objectives of the study were to examine the surface of different elastomeric impressions on contact with various gloves.Materials and Methods:This clinical study included a total of eighty specimens of two types of the putty elastomeric impression material were hand manipulated by wearing three different gloves materials and is placed on a marked area of a clean and alcohol-treated glass slab at room temperature. The specimens examined for any signs of polymerization inhibition. The specimen will be rated as being “inhibited” if any residue remains on the glass slab and absence of the above will result as “no inhibition.”Results:The results showed no interference with the polymerization inhibition of the selected elastomers followed by the nitrile glove. The latex gloves showed inhibited set of the elastomeric impression material but set after sometime confirming time-dependent inhibition of the impression material.Conclusion:This study shows that the use of latex and sometime nitrile gloves during crown and bridge procedures should be contraindicated and the use of vinyl gloves should be stressed when working with elastomeric impression materials.

Among the numerous techniques of oral rehabilitation, precision attachments are considered as a good treatment option in removable (RPD) as well as fixed partial dentures (FPD). Precision attachments enhance patient’s self-confidence and selfimage as they help in facilitating aesthetic, functional and retentive replacement of teeth that are missing in the oral cavity. They can improve the aesthetics by eliminating the clasp assembly in cast partial dentures (CPD). This particular case report explains the treatment sequence and approach for the utilisation of attachments in a Kennedy Class 2 situation. A successful removable partial denture includes a precise diagnosis with meticulous treatment planning. However, re-establishment of partially edentulous arch is particularly challenging in distal extension situations classified as Kennedy’s class 1 or 2 conditions.1 In such clinical cases, where a fixed prosthesis cannot be fabricated, a prosthodontist often suggests an implant retained prosthesis that is not routinely possible because of the insufficient available bone width and height.2 Thus to ensure functional and aesthetic substitution of lost teeth, an attachment secured RPD can be considered as a good treatment option in such cases. Attachments are constructed in a ready to place form (pre-fabricated) known as precision attachments. Another one is semi precision attachment where the segments have to be constructed by dentists or dental technicians because it requires casting for incorporating into fixed unit of restoration.3 Hence precision attachments are considered as possible alternatives when patients demand for a fixed restoration in distal extension cases. Various extra coronal attachments are available and used in distal extension cases. Preci-Sagix is considered as an ideal extra coronal attachment for removable partial dentures and also in over denture cases. It is accessible in two sizes, 1.7 mm mini or 2.2 mm standard and is selected according to the permitted space. The male component is available in three varieties, a plastic castable pattern (any hard alloy), cast to no prax (only non-precious alloy) and a threaded male and base ring (2.2 mm size only).4 These attachments produce vertical, horizontal and rotational movements during its function which supports the prosthesis by transferring harmful forces from the abutments to the supporting structures by its passive movement, which helps in the rehabilitation of distal extension cases.5 This case report explains restoration of partially edentulous arch by incorporating a Preci Sagix attachment in mandibular cast partial denture retained by a six-unit FPD and a maxillary conventional cast partial denture.
